Single‐ and Dual‐Atom Configurations in Atomically Dispersed Catalysts for Lithium–Sulfur Batteries
Advanced Functional Materials, EarlyView.Single‐atom and dual‐atom‐based atomically dispersed catalysts (ADCs) effectively address the shuttle effect and sluggish redox kinetics in Li–S batteries. With nearly 100% atomic utilization and tunable coordination environments, ADCs enhance LiPSs adsorption, lower conversion barriers, and accelerate sulfur redox reactions.

Low loss and dispersion engineered ZnSe waveguides at telecom wavelengths
AIP Advances, 2021 We have successfully fabricated a dispersion engineered ZnSe waveguide. The ZnSe film was deposited on a CaF2 substrate by radio frequency magnetron sputtering, and the waveguide was patterned directly on the ZnSe films by UV lithography and inductively ...

A Colloidal Quantum Dot Thermistor and Bolometer
Advanced Materials, EarlyView.This work introduces colloidal quantum dot thermistors employing a potential barrier structure to tune the activation energy of transport and hence the temperature coefficient of resistance (TCR). Upon integration with plasmonic absorbers, the CQD‐based bolometer device enables room‐temperature wavelength‐selective photodetection across the mid‐ to ...

Effect of Indium nano-sandwiching on the structural and optical performance of ZnSe films
Results in Physics, 2017 In the current study, we attempted to explore the effects of the Indium nanosandwiching on the mechanical and optical properties of the physically evaporated ZnSe thin films by means of X-ray diffractions and ultraviolet spectrophotometry techniques ...

Advanced Materials, EarlyView.A highly‐emissive organic photovoltaic employs donor–acceptor pairs with alternately localized frontier molecular orbitals, preserving high triplet energies and small reorganization energies to suppress non‐radiative recombination. As a result, it exhibits a high open‐circuit voltage approaching the Shockley–Queisser limit and a high ...
