Resume : The n-type semiconductor gas sensor is widely used for the detection of reducing gas such as CO, H2, and volatile organic compounds VOCs gases. In particular, SnO2 is known as a representative semiconductor gas sensing material because it is chemically stable and having high electron mobility. Due to increased environmental concern, there is an increasing demand for semiconductor gas sensors that are selective and responsive towards H2S gas, which is harmful for living being.
The H2S is a toxic and malodorous gas produced from coal mine, coal oil gasoline and natural gas manufacturing processes, and wastewater treatment plants. In order to increase the gas sensing response of SnO2 based gas sensor, the addition of noble metals Pt, Au, Pd or the structural modification of SnO2 nanoparticles NPs is suggested. Out of these noble metals, Au NPs is reported to be a good catalyst for the adsorption and decomposition of H2S gas.
Among various nano-structures, core-shell NPs having Au as core material could be a better sensing material for H2S gas. The core-shell structure can prevent the agglomeration and undesired growth of Au NPs. In this study, Au SnO2 core-shell NPs has been synthesized by microwave-assisted hydrothermal method.
We also observed the electrical resistance change of Au SnO2 core-shell NPs according to the content of H2S gas from 2 ppm to ppm for investigating sensing response and selectivity behavior. Resume : Recently, smart sensors and portable electronics have been developed due to the need of customers. The development of conductive fibers has also increased with this new trend of wearable devices.
The conductive fibers can be combined with textiles and consequentially they will offer people more intelligent life. Among them, smart color changing fibers become a noticeable research topic for their various potential applications, such as portable electronic facilities, sensors, smart display, camouflage applications and soft robots.
For years, there were diverse researches about smart color changing fiber using thermochromic, electrochromic and mechanochromic method. However, there are still things to do to simplify the process and get more controllable smart color changing conductive fiber. This study is a combination of conductive fiber type device and thermal discoloration.
Therefore, only the voltage or the current caused the temperature change and the material composition change to realize the heat discoloration. On the contrary, this study has caused the temperature change by using the change of the resistance of the fiber depending on the strain by using the fiber having the conductive and elasticity. Under the same voltage, it was confirmed that as the fiber was stretched, the resistance increased and the amount of current flowing decreased. A fiber-based, switchable interconnector in which the resistance change causes a temperature change can serve as a motion sensor.
You can also visually identify temperature changes by coating the conductive fiber with a material made with Zion powder. In addition to acting as a motion sensor, we have created a sensor and a display-integrated fiber-based thermochromic device that allows instant visual confirmation of measurement accuracy.
This study is expected to be able to be used as a wearable display for motion detection that changes color according to movement by combining with sportswear. However, their operational and environmental stability is highly dependent on organic semiconductor OS degradation. Environmental incubation in water and operational stability bias stress of the as-prepared EGOFETs was evaluated and a possible model for P3HT degradation was proposed. A strategy to preserve device performance and shelf life was also investigated.

Cioffi, Sens. Actuators: B. Chemical , Some like WO3 show excellent sensing response to nitrogen dioxide as well. However, most SMOs response poorly to carbon dioxide. The results indicate that it is possible to tune the operating temperature of the carbon dioxide sensor by changing the configurations of the n type ZnO and p type LFCO thin films without changing the behavior of the sensor with respect to the same concentration of carbon dioxide.

Resume : The development of freestanding fiber-type chemiresistor, having high integration ability with various portable electronics including smart clothing system, is highly demanding for the next-generation wearable sensing platform. In this work, we present potential suitability of the freestanding reduced graphene oxide RGO fiber functionalized with platinum as a sensitive humidity sensor.
As a result, nRGO fiber can effectively detect wide humidity levels in the range of 6. A sensitivity of 4. Real-time and portable humidity sensing characteristics are successfully demonstrated toward exhaled breath using Pt-nRGO fiber integrated on a portable sensing module. Resume : Organic-inorganic perovskites such as CH3NH3PbI3 emerged as attractive materials with outstanding potential in applications such as low cost high efficiency solar cells or photodetectors. However, the complex structure of these materials and the difficulty of manipulation hinder their integration into devices.
This procedure enables the use of laser-induced forward transfer LIFT as a powerful technique for direct writing of organic-inorganic perovskite patterns as a proof of concept for the fabrication of solar cells. A promising open voltage of 0. They crystallize in the orthorhombic space group Pnma and their electrochemical properties were systematically investigated at different concentrations of the KOH electrolyte 1M, 3M and 7 M using chronopotentiometry, potentio-dynamicpolarization and chronoamperomertry techniques at K  , , .
Like the relationship between the discharge capacity and concentration of electrolyte, the electrochemical kinetic analysis indicates that the exchange current density and the hydrogen diffusion coefficient of the oxide LaGaO3 increase with the rise of the concentration of electrolyte at high temperature . Thereafter, it decreases to 12mAh g-1 and remains stable at the other 17 cycles .
The measurements showed that the electrochemical performance of the LaGaO3 oxide has been greatly influenced by the variation of KOH concentration. Faster activation and highest discharge capacity are achieved at KOH 7M. The kinetic properties of the working electrode have been significantly improved by the elevating the electrolyte concentration.
Resume : Three kinds of AVIMMR intermediates were synthesized by using 1-vinylimidazole with bromoethane, bromopropane and bromobutane respectively by controlling the experimental temperature and reaction time. The VIM was added to the ionic liquid to prepare the blend system. The two ionic liquids were obtained by cyclic voltammetry, chronoamperometry and AC impedance. Resume : Scavenging energy from various types of mechanical forces through piezoelectric nanogenerator PNG has been a considered great alternative for powering up low-power portable devices and self-powered electronic systems.
Under finger imparting, the 2. In addition, the fabricated PNG is successfully exploited to generate electrical power by converting mechanical energy from a wide variety of human activities such as human body movement, walking, and machine vibration and also exhibits outstanding durability for about four weeks without any deterioration in the output performance. Resume : A new transparent electrode has widely been researched with numerous applications.
Herein, we report potential application as multifunctional heater of two-dimensional transition metal carbide, called as MXene, first time. Also, the existence of majority terminal group -OH form the hydrophilic surface, enabled to solution process within water. We prepared large-area MXene thin-film heater with transparency on the rigid glass substrate by controlling the chemical interaction between MXene and glass.
Moreover, the MXene-based heater prepared on the non-rigid substrate PET exhibited both physical stability and great heater performance under mechanical deformation. For the practical applications, we simply coated the thin MXene flakes on the surface of PET fibers treated with amino silanization.
We prepared MXene threads-based adaptable heaters with diverse shapes through sewing or weaving processes, in which the MXene flakes were strongly adhered on the PET fibers. The flexible, and mechanically adaptable MXene threads heater enabled to the control of body temperature by attaching the heater on the body. Resume : We present nanomaterials-based force sensors which can be mounted on hand-held surgical tools.
Providing information about the force applied on surgical tools enables surgeons to perform surgeries efficiently. Additionally, it can minimize the damage from operations. With the suggested concept of two facing electrodes application, it is easy to control the sensitivity of the sensor by changing the types of applied nanomaterials or controlling the conductivity of each electrode.
For instance, the sensitivity can be efficiently enhanced by widening a conductivity gap between applied nanomaterials. Novel approach with crumpled electrodes facing each other offers not only wider working range for applied force measurement but also better sensitivity by taking advantage of gradually changing number of contact points. In contrast with flat electrodes applications, fabricated sensor returns to the original state because the wrinkles provides a restoring force.
By integrating four pairs of facing electrodes on hand-held surgical tools, information about the direction of applied force is also available.
Nanomaterials for energy applications via scalable fabrication routes
Suggested system shows the possibility of efficient force measurement and direction awareness for smart surgical tools using nanomaterials-based force sensor. Resume : Titania nanoparticle-loaded mesoporous silica has been studied as a promising photocatalytic material for the removal of organic pollutants. In this study, we synthesized titania nanoshells deposited on mesoporous silica SBA by using layer-by-layer LbL assembly method.
For comparative studies, various amounts of titania were post-impregnated into SBA by sol-gel reactions. The morphologies and photodegradation properties were systematically investigated. Samples prepared by LbL assembly methods show shell-like depositions of titania around mesoporous silicas, while samples prepared by sol-gel reactions present homogeneous dispersions onto mesoporous silicas. Photocatalytic performances on the decomposition of sodium dodecylbenzenesulfonate SDBS were examined. The LbL-samples exhibit enhanced photocatalytic performance compared to that of the sol—gel samples.
This work could help in design of titania loaded nanomaterials for various applications such as biosensors, solar cells, and photocatalytic applications. Resume : In present study ZnO based sensors have been studied in details adopting two different methodologies, doping and nano composite. On the other hand, Ag nano particles were decorated onto ZnO nanoparticles. Functionalization of ZnO nanoparticles with surface decoration of Ag nanoparticles nm has been achieved by continuous gas phase deposition system.
XRD-spectra reveal the phase formation and crystallinity of the samples. This current approach enables us to fabricate cost-effective and low-temperature environmental gas sensor with high selectivity for the detection of CO gas. Different mechanisms were found to dominant in case of doping and composite and were studied in detail to explain the change in sensing behavior for both type of sensors.
This study provides a way of choosing methodologies used for selecting different kind of gases. Resume : A flagship application of optical chemical sensors is the real-time monitoring of cell cultures for the biomedical application. The sensors work by the quantification of physical-chemical parameters, e.
The principle of most optical chemical sensors studied in the literature is based on variations in the fluorescence signal intensity or lifetime when a fluorescent pigment fluorophore , incorporated in a matrix permeable to gaseous or ionic species and excited to an adequate wavelength laser, LED , is brought into contact with an analyte, e. DO in an aqueous medium. Their integration in the form of miniaturized devices is based on the deposition of a thin layer matrix doped with the fluorophore.
While this configuration is perfectly suited to miniaturize devices, it suffers from limitations in terms of detection limit due to the small amount of fluorophores incorporated in the thin-film matrix and to the small fraction of emitted light redirected toward the photodetector.
This work aims at proposing a new sensor configuration based on the sol-gel fabrication of fluorophore-doped channel waveguides equipped with diffracting couplers at both ends of the waveguide. In this presentation, we will first describe the operating principle of this sensor and the sol-gel procedure implemented for the fabrication of the selected architecture.
We will then present opto-geometric characterizations and modeling as well as fluorescence measurements performed on full-plate thin films, showing the compatibility of the chosen architecture with the objectives. A first proof of concept of light coupling between the waveguide and the diffracting couplers will finally be presented. Typically, optimal working temperature of ZnO based gas sensors is above oC. However, ZnO has a problem in that it has no selectivity for target gases. Recently, as the hydrogen age comes, there is a growing interest in hydrogen gas sensors having selectivity to hydrogen gas.
Meanwhile, noble metal nanoparticles NPs have been used to improve the sensing properties of gas sensor. Among the various noble metal catalysts, palladium has excellent ability to adsorb hydrogen, so that it can increase the selectivity of the gas sensor to hydrogen gas when used as a catalyst. However, since palladium can be easily oxidized at a high temperature, when it is used as a catalyst of a gas sensor at a high operating temperature, it is oxidized so as to lose its function as a metallic catalyst.
Therefore, palladium alloy needs to be considered as a catalyst. In the core-shell structure, the shell helps maintain the catalytic properties of the metal core. In this study, Pd-Au alloy nanoparticles were synthesized to prevent oxidation of palladium. Resume : Electrochemical, non-enzymatic glucose sensors attract huge attention in the field of health monitoring portable devices. The highly selective and sensitive electrode material playing the most important role in construction of such devices can ensure reliable determination of sugar level. Therefore, in this work, we present the glucose sensing platform based on Ti nanodimples filled with Au nanoparticles NPs.
Ti foil was anodized and then chemically etched to produce structured material. Electrochemical performance for different glucose concentrations was investigated in both neutral and alkaline solutions. Selectivity of obtained material was tested in presence of various interfering species, e.
Energy autonomous electronic skin
The presence of Nafion membrane on the surface of sensor allowed the complete reduction of electrochemical response of above mentioned compounds. Moreover, high sensitivity as well as resistance to multiple measurements and mechanical stress indicate that obtained material exhibits promising properties towards glucose detection and could be regarded as key component of non-invasive glucose sensor. Resume : Waste heat at high temperature ranges has high potentiality, but most of it is currently dumped into the environment without being used in any reasonable way.
For stable thermal contact between the thermoelectric generator and the heat source at high temperature ranges, thermal interface material having both of high thermal conductivity and high-temperature stability is necessary. We are going to show excellent physical properties printability, high temperature stability, and thermal conductivity of the thermal interface material and demonstrate their impact on the interface thermal resistance and the thermoelectric power generation characteristics.
Resume : Among two dimensional materials beyond graphene, Molybdenum Disulphide molybdenite being in the single layer phase a direct band gap semiconductor, is the prototypical system for optoelectronic applications. Its electronic and optical properties are tuneable as a function of layer number and also by doping. We present here a systematic resonant Raman and photoluminescence PL study of few and single layer mechanically exfoliated MOS2.
The mechanical exfoliation method is optimised and quantitatively rationalised. We demonstrate that the electronic properties of the single and few layer MoS2 can be tuned by creating sulphur vacancies via thermal induced sulphur desorption. This leads to a controllable engineering of the photoluminescence response and tunes the relative intensity ratio of charged trions and neutral excitons.
By comparing the PL response of single layer MoS2 with thermally tuned sulphur vacancy concentration with resonant micro-Raman spectra we derive a self consistent picture of the optical and electronic properties of defect engineered MoS2 and propose evidences for the spatial symmetry of the exciton wave function.
The effects of thermal annealing are also discussed in relation to post exfoliation layer engineering and of the gas sensing response of the material. Resume : In recent times, graphene oxide GO and reduced graphene oxide rGO have attracted much attention in the development of nano-composites for sensor and energy related applications. However, inhomogeneities in the structure of GO and rGO have limited the use of these materials in above applications.
GO was synthesized under different oxidizing times using Improved Hummers method from high crystalline vein- type graphite. Further, the results of UV-Visible spectroscopic technique indicate that there are no significant differences in the amount of MB adsorbed on all GOs. However, prominent variations are observed in the amount of MB adsorbed on rGOs, indicating structural differences among the rGOs.
These results reveal differences in spatial distribution of oxygen functionalities among the GOs synthesized under different oxidation times. Further the information presented is important in the analysis of surface area using MB on graphene-based nano-composites. Resume : In this work, we describe an approach that suppresses recombination, in turn, enhancing the photoresponse via engineering of photon induced electron transfer PET , reporting one of the highest enhancement till date. Zinc oxide ZnO has been widely explored for UV detection despite its large exciton binding energy 60 meV that can inhibit its photoresponse.
ZnO film when coated with carbon nanotubes CNTs and nitrogen-doped CNTs NCNTs facilitates electron transfer and inhibits recombination, increasing its photocurrent across wavelengths between to nm. This is one of the interesting approaches to enhance the photoresponse of a material. The same approach was used to enhance photoresponse from a CsBi3I10 film as well, an inorganic lead free halide perovskite.
Resume : Mesoporous oxide films filled with metallic nanoparticles has been widely used to enhance photocatalytic properties by reducing charge recombination, due to a controlled porosity and the presence of light absorbing metallic catalyzers.

To study and distinguish these mechanisms, we chose to study nanostructured electrodes made of Ag nanoparticles inside a semi-conductor oxide TiO2 or Fe2O3 with a control of porosity and particle dispersion as an improved photocatalytic system. We performed electrochemical experiments in a three electrode configuration under various ranges of light irradiation, from UV to visible, to determine the variations of redox potentials and photocurrent and thus getting insights on the photochemical mechanism and material structure influence.
A positive shift of 0. Silver nanoparticles are also modified due to diffusion through the electrolyte and electrochemical Ostwald ripening during photoelectrochemical experiments and have been characterized by electron tomography. Resume : Our laboratory has developed a new synthetic procedure for generating periodic arrays of metallic nanostructures shaped as hexagonal or triangular nanoplates using a room temperature light-activated growth mode.
Such structures have the potential to act as the active components for the detection of biological and chemical analytes using various sensing modalities e. The synthesis is reliant on the formation of Au seeds exhibiting planar defects — without such defects the growth mode is deactivated. Through the engineering of defects, which have been extensively studied using Titan TEM imaging and electron diffraction, such structures have now been produced in high yield.
Here, we will describe the techniques used to generate periodic array of seeds, demonstrate their utility in forming substrate-based metallic nanoplates and provide an understanding of the opportunities and challenges that lie ahead. Specifically targeted is the fabrication of such arrays on Si substrates since it can result in technologically relevant substrate-nanostructure electronic interactions such as the injection of the hot electrons generated by plasmonic excitation into the substrate. Resume : The growing interest in carbon-based materials which represent a wide family due to the manifold allotropic forms carbon nanotubes CNTs , graphene, nanodiamond, etc.
As member of carbon materials family, CNTs and graphene are distinguished material that can be used as matrix able to host functional materials such as metal oxides MOX or conducting polymers CPs etc. Such an association allows to build functional hybrids materials with excellent properties derived from the combination of the host matrix properties CNTs or graphene and the functional materials properties MOX or CPs. For sensors application, such hybrid materials fabrication is of commensurable importance since it allows to finely tune the functional nanomaterials composition to reach unique sensing performances.
The role of surface modification to access to sensitive sensors as well as the synthesis and characterization of such functional materials will be presented. Apart from the sensing performances of the hybrids functional materials, the association of the two entities has also enable the elucidation of the interaction mechanisms through understanding the surface reactivity of the nanomaterials.
Resume : With the flourishing development of electronic interactive devices, the perception of smell has shown the potential to combine with multimedia. The controlled release of aroma plays an important role for the integration of olfactory senses into various functional devices. Ti3C2 MXene is a promising material for the controlled release of aroma molecules due to the abundant surface termination groups and metallic nature. The aforementioned properties allow aroma molecules to be adsorbed on the Ti3C2 MXene surface and in situ release by resistive thermal desorption.
With the in situ thermal desorption of aroma molecules, it prevents interface issues between the molecule encapsulation materials and the electric heating source. The Ti3C2 MXene heater shows the temperature ramping to oC within 1 second and the stable heating for more than 20 minutes. Pyocyanin PYO is currently considered as a biomarker for Pseudomonas infections that is one of the most common pathogens causing respiratory tract infections in immunocompromised patients.
To decrease the influence of the matrix, the substrates were incubated in 5 times with water diluted solutions. The characteristic peak of PYO at cm -1 could be still distinguished at a concentration of 6. The results illustrate the potential of the developed SERS-active substrates to reduce the detection time of bacteria by detecting a metabolite directly from complex matrixes without the need for lengthy extraction protocols and laborious detection schemes.
Resume : Wearable electronics is attracting much attention that can make our lives more enriching. The most important thing in wearable electronics is conductive fibers. Previous studies have shown that metal fibers have high electrical conductivity but not suitable for use in garments due to poor performance due to corrosion. Therefore, in this study, conductive fibers that can be used for clothing were manufactured using carbon nanotubes CNTs instead of conventional metals.
We introduced insulative fiber layer on the CNT fibers using a braiding process. In addition to excellent electrical conductivity, the conductive fibers developed in this study were flexible enough to be sewn to clothing. For example, we fabricated a 2D capacitive type of textile touch sensor using the developed conductive fibers. Textile touch sensors can be fully integrated into clothings, contributing to wearable electronics that can be applied to many types of smart apparel. Resume : Sensors and biosensors play a leading role in devices and systems destined for human health and safety.
However, most of the existing sensor based systems require complicated electronic structures and high manufacturing costs. Therefore, cheap devices on light, flexible substrates are required. This work deals with the design, fabrication, and characterization of a flexible, wearable, and low cost sensor suited for on-body physiological monitoring based on nanocomposite materials polymers and graphene and fabricated by laser-induced forward transfer LIFT.
Conventional LIFT consists of the irradiation, using a pulsed laser, of a thin layer of an absorbing material the donor that has been deposited onto a transparent substrate. The layer is irradiated through the substrate and the light-matter interaction which takes place at the interface generates a strong increase of the local pressure. As a result, a small piece of the thin film located above the irradiated area is ejected as a pixel from the substrate surface and deposited onto a target substrate the receiver arranged in close proximity to the donor substrate.
The size of the ejected material is controlled by the size of the incident laser spot. In this work, we printed different polymer:graphene nanocomposites onto flexible substrates coated with an insulating layer, for ex. Parylene C, which prevents electrical contact with the body fluids. The biosensors fabricated by LIFT are used for the detection of heavy metals in human body fluids.
Promising results i. Resume : Nowadays the development of natural biomaterials as promising building polymers for biodegradable, biocompatible and environmentally friendly electronic devices is of great interest. As the common natural polymers, cellulose and its derivative have the potential to be applied in the devices owing to the easy processing, nontoxicity and biodegradability.
Here, write-once-read-many-times resistive switching devices based on biodegradable carboxymethyl cellulose-graphene oxide CMC-GO nanocomposite are demonstrated for the first time. The hybridization sites formed by the gelation of CMC and GO molecules contribute to the excellent memory behaviors.
This newly designed cellulose-graphene-based polymer nanocomposites are quite cheap and easy processed for large scale manufacturing of memory devices and can further contribute to future biodegradable data storage applications such as portable stretchable displays, wearable electronics and electronic skins in the coming age of artificial intelligence. Once implemented into tunnel junctions, our 2D-0D heterostructures demonstrate robust and sharp conductance oscillations resulting from efficient Coulomb blockade mechanisms.
Finally, the spintronics properties of 2D—0D heterostructures are unveiled .

Nano-bioengineering of enzymes is aiming to enable conversion of cellulose from wood chips, corn stalks, unfertilized perennial grasses, etc. Cellulosic nanomaterials are projected to be less expensive than many other nanomaterials and, among other characteristics, tout an impressive strength-to-weight ratio. Nanostructured ceramic coatings exhibit much greater toughness than conventional wear-resistant coatings for machine parts. Nanotechnology-enabled lubricants and engine oils also significantly reduce wear and tear, which can significantly extend the lifetimes of moving parts in everything from power tools to industrial machinery.
Nanoparticles are used increasingly in catalysis to boost chemical reactions. This reduces the quantity of catalytic materials necessary to produce desired results, saving money and reducing pollutants. Two big applications are in petroleum refining and in automotive catalytic converters. Nano-engineered materials make superior household products such as degreasers and stain removers; environmental sensors, air purifiers, and filters; antibacterial cleansers; and specialized paints and sealing products, such a self-cleaning house paints that resist dirt and marks.
Nanoscale materials are also being incorporated into a variety of personal care products to improve performance. Nanoscale titanium dioxide and zinc oxide have been used for years in sunscreen to provide protection from the sun while appearing invisible on the skin. Electronics and IT Applications Nanotechnology has greatly contributed to major advances in computing and electronics, leading to faster, smaller, and more portable systems that can manage and store larger and larger amounts of information.
These continuously evolving applications include: Transistors, the basic switches that enable all modern computing, have gotten smaller and smaller through nanotechnology. At the turn of the century, a typical transistor was to nanometers in size. In , Intel created a 14 nanometer transistor, then IBM created the first seven nanometer transistor in , and then Lawrence Berkeley National Lab demonstrated a one nanometer transistor in ! Ultra-high definition displays and televisions are now being sold that use quantum dots to produce more vibrant colors while being more energy efficient.

Making flat, flexible, lightweight, non-brittle, highly efficient electronics opens the door to countless smart products. Nanoparticle copper suspensions have been developed as a safer, cheaper, and more reliable alternative to lead-based solder and other hazardous materials commonly used to fuse electronics in the assembly process. Nanomedicine, the application of nanotechnology in medicine, draws on the natural scale of biological phenomena to produce precise solutions for disease prevention, diagnosis, and treatment.
