Low Power Resistive Photon- and Gas- Sensors
Sensors, be it for temperature, pressure, acoustic, light or gas to name a few have become an indispensable part of human life. Light sensors or photodetectors have widespread usage in modern portable electronics as camera ...
Engineered Catalytic Metal—Metal-Oxide Nano-heterostructures for CO Oxidation
Owing to its interesting chemistry and toxic nature, catalytic oxidation of CO is of both fundamental and practical interest. Two applications, viz. CO conversion in the catalytic converters and pre-treatment of CO-rich ...
Oxidation of CO Catalysed by Nanometric Mono and Bi-Noble Metals on Various Oxide Supports
Air pollution results mainly from the injurious smoke emitted by cars, buses, trucks, factories etc. This smoke contains carbon monoxide, unburned hydrocarbons and oxides of nitrogen and sulphur. In case of cars, catalytic ...
Exploring Topological Phases of Matter using Density Functional Theory and Machine Learning Approaches
Topological phases of matter such as topological insulator (TI), quantum anomalous Hall insulator (QAHI), nodal line semimetal (NLSM), and triple point metal (TPM) can be realized by manipulating the spin-orbit coupling ...

alluaudites as a niche class of compounds forming the
rich treasure house of sodium insertion hosts. The
potential of this open frame-worked alluaudites is
immense and ...
Structural and Electrochemical Investigation of Fluoro(hydroxy)phosphate Based Cathode Materials for Secondary Batteries
Structural and electrochemical investigation of LiFePO4OH hydroxyphosphate material. The synthesis and structure of this material is explained. The hydrothermally synthesized material crystallizes in triclinic structure ...
Accelerated search for thermoelectric and topological materials using first-principles and machine learning
In summary, we have performed first-principles calculations to study the topological phase transitions
in chalcopyrite compounds as a function of hydrostatic pressure. These compounds are
topological insulators in the ...
Electrical and Opto-Electronic Devices Based on SnSe2 Thin Films
SnSe2 is a semiconductor with unique and interesting properties such as band gap with layer thickness dependence. Theoretically, it has been predicted that the band gap can be varied between 1.2 and 2.04 eV. This range of ...
Transition metal phosphide nanostructures encapsulated in N,P co doped nanotubes for water splitting in wide pH range
In order to make clean and sustainable energy conversion, systems primarily requires the development of highly efficient and robust catalysts. One of the main challenges for designing the catalysts is to minimize the cost ...
Exploration of exfoliation, functionalization and properties of MXenes via first-principles and machine learning
The monolayers of early transition metal carbides and carbonitrides named MXenes are exfoliated from the corresponding bulk MAX phases (Mn+1AXn, M = early transition metal, A = group IIIA or IVA element and X = carbon ...
