Kwon. 1. 1. , KIST, Seoul, Korea (the Republic of). Show Abstract. Gas sensors based on semiconductor nanostructure are widely used from healthcare to environmental monitoring. Advantages of the nanostructure- based gas sensors such as higher sensitivity and faster responsibility with shorter recovery time originate from single crystallinity as well as high- surface area to volume ratio.
When the semiconductor nanostructure is incorporated with noble metal nanoparticles which work as surface- decorating nanoparticle, even enhanced sensing performances are expected due to more efficient and faster electron exchange between gas species and the nanostructures. In this presentation, we report experimental study on the preparation of hybrid nanostructures composed of single crystalline Ge nanowires (NWs) which are coated with Ag nanoparticles (NPs) for the application for highly sensitive and fast gas sensors detecting gaseous NOx, NH3, and CO2. The Ge NWs were synthesized via vapor- phase reaction in conjunction with thermal evaporation. The synthesized Ge NWs are surrounded by amorphous Ge. O2 thin sheath due to natural oxidation in ambient condition. The Ge NWs- Ge. O2 sheath core- shell structure suffers galvanic reaction with aqueous solution of Ag precursors, in which Ag precursors are precipitated onto the surface of Ge NWs, whereas Ge NWs suffers oxidation with dissolution of the amorphous Ge. O2 sheath. We fabricated solid devices for the gas sensing, in which the sensing materials are Ag NPs on Ge NWs and Ge NWs- Ge.
O2 sheath without surface Ag NPs. We compared gas sensing performances of the two nanostructures, and found that the hybrid nanostructures exhibit better gas sensing performances (i. In particular, we observed notably highly enhanced sensitivity for NOx gas of concentration as low as of 0. We provided a mathematical model to elucidate the enhanced gas sensing performances based on parameter- dependent differential equations for adsorption and desorption dynamics of gas species on the surface of the nanostructure, and the model could successfully explain the origin of the enhanced gas sensing performances in quantitative manner. Based on a similar enhancing mechanism, the present study can work as a basis to prepare other kinds of sensors for dilute biomolecules detection with highly enhanced sensitivity.

Indira Gandhi Center for Atomic Research, Kalpkham, India. Show Abstract. In the present investigation, we report the cost- effective, surfactant- free and scalable synthesis technique for Lead Telluride (Pb. Te) nanocubes by chemical precipitation method followed by spark plasma sintering (SPS). The synthesized nanocubes were characterized by X- Ray Diffractometer (XRD), High Resolution Transmission Electron Microscope (HRTEM) and X- Ray Photoelectron Spectroscopy (XPS).
The HRTEM studies clearly indicate that the nucleation centers (spherical) evolve into nanocubes by addition of the Pb and Te atoms. The thermopower measurement performed on as sintered Pb. Te nanocubes exhibited an enhancement of 4. V at 4. 00 K, which is higher than the reported values at this temperature. This enhancement could be attributed to the potential barrier scattering at the grain boundaries.
Further, significant reduction in thermal conductivity was observed due to its higher surface area with many facets effectively scattered various length scales of phonons for Pb. Te nanocubes and thus leading to an increase in ZT. The dimensionless figure of merit (ZT) was found to be ~ 0. K, which is three time higher than the reported bulk values at this temperature. Moreover, thermoelectric compatibility factor with respect to the temperature has been calculated and it is quite comparable with similar material synthesized employing different processing routes. Enhanced thermoelectric properties coupled with moderate compatibility factor makes Pb. Te nanocubes as a potential candidate for green energy generation.

Physics, Indian Institute of Technology Delhi, New Delhi, Delhi, India. Show Abstract. Transition metal oxides have displayed a wealth of unique optical, chemical, physical, and electronic properties, which have attracted the attention of researchers and engineers alike. Vanadium pentoxide (V2.
O5) offers Multi- valency, wide optical band gap and good thermal and chemical stabilities, especially in the form nanostructured thin film (NSTs). These properties lead to fascinating applications like in electrochromic devices, power storage devices, gas sensing, and catalysis. Here we report the synthesis of long order vanadium pentoxide (V2. O5) nanoribbons over a wide area of 2. PASP). The nanoribbon growth has been achieved on glass substrates with Nickel acting as catalyst layer. Thickness of catalyst layer is kept constant at 5. Vanadium precursor is kept in vacuum chamber at optimised partial pressure of oxygen gas.
Oxygen plasma accelerates the formation of vanadium oxide which is then sublimated and deposited on substrate. The gas environment acts as transport medium for sublimated oxide from precursor to substrate. The growth parameters such as partial pressure, plasma voltage and boat voltage (for heating precursor) have been optimised. In this report, we present the effect of source temperature (temperature at which precursor is heated) on the synthesis of long order nanoribbons. Vanadium precursor when heated in plasma environment lead to formation of vanadium oxide, which is sublimated at optimum temperature to deposit on substrate. Samples were deposited at three different source temperatures, 3.
C. SEM micrographs taken at 5. Kx, 1. 0Kx and 2. Kx magnifications show ribbon like morphology of nanostructures grown. The samples have been studied using XRD and Raman spectroscopy, which confirms the presence of long order in V2. O5 nanoribbons. It is also revealed that no other phase besides α- V2.
O5 is present in samples under study. HRTEM and SAED studies reveals orthorhombic structure of nanoribbons along with fringe pattern which again confirms the composition of nanoribbon to be V2. O5. It is revealed from studies that at low temperatures, there is short range order leading to deposition of amorphous V2.
O5. When temperature is increased, short order gives way for long range order and highly crystalline α- V2. O5 is obtained. The surface morphology also changes with respect to temperature, as substrate is kept close to precursor at a distance of about 5 mm.

Show Abstract. Hybrid materials can be broadly defined as a class of composites with organic or biological and inorganic components intimately mixed with one another where atleast one of the components has dimensions ranging from a few angstroms to several nanometers. In contrast to mixtures whose properties can often accurately be described as an arithmetic average of the properties of their components, the distinctive feature of a truly hybrid material is that material synergies lead to performance that is greater than the sum of its parts, which can happen when there are strong, non- linear interactions between the constituent components and the role of their interfaces become predominant.
