We report on the realization of ZnO homojunction light-emitting diodes (LEDs) fabricated by metalorganic chemical vapor deposition (0001) bulk substrate. The p-type epilayer was formed nitrogen incorporation using N2O gas as oxidizing and doping sources. Distinct electroluminescence (EL) emissions in blue yellow regions were observed at room temperature naked eye under forward bias. EL peak energy coincided with photoluminescence epilayer, suggesting that emerge from epilayer. In addition,...
The use of solid acid catalysts for sorbent regeneration is an emerging approach to improve the energy efficiency CO2 capture processes.

Asymmetric contacts were used to assemble extremely photosensitive and self-powered photodetectors (SPDs) on rigid polyimide (PI) substrates based one-dimensional (1D)-CdS nanobelts.
The nature of the quantum-to-classical crossover remains one most challenging open question Science to date. In this respect, moving objects play a specific role. Pioneering experiments over last few years have begun exploring quantum behaviour micron-sized mechanical systems, either by passively cooling single GHz modes, or adapting laser techniques developed in atomic physics cool low-frequency modes far below temperature their surroundings. Here instead we describe very different...
Low-cost multicomponent alloyed one-dimensional (1D) semiconductors exhibit broadband absorption from the ultraviolet to near-infrared regime, which has attracted a great deal of interest in high-performance flexible optoelectronic devices. Here, we report facile one-step fabrication rigid and photodevices based on 1D cadmium-sulfur-selenide (CdSxSe1-x) micro-nanostructures obtained via vapor transport route. Photoresponse measurements have demonstrated their superior spectral...
Nitrogen oxides (NOx) and chlorinated volatile organic compounds (CVOCs) are major environmental pollutants, posing severe risks to human health ecosystems. Traditional single-component catalysts often fail remove both pollutants efficiently, making synergistic catalytic technologies a critical research focus. In this study, mesoporous HPW-CS-Ce-Ti oxide catalyst, modified with H3PW12O40 (HPW) chitosan (CS), was synthesized via self-assembly. The optimized 10HPW-CS-Ce0.3-Ti catalyst achieved...
Abstract Perovskite light‐emitting diodes (PeLEDs) have reached near‐unity photoluminescent quantum yields (PLQYs), but further improvements in electroluminescent efficiency are constrained by interfacial energy losses between the emissive layer and charge transport layers. In this study, multifunctional carbon dot organic frameworks (CDOFs) introduced as a dual‐interface modification material for perovskite layer. This approach effectively passivates both upper buried interfaces, boosting...

We report on experiments addressing the non-linear interaction between a nano-mechanical mode and position fluctuations. The Duffing non-linearity transduces Brownian motion of mode, other non-linearly coupled ones, into frequency noise. This mechanism, ubiquitous to all weakly-nonlinear resonators thermalized bath, results in phase diffusion process altering motion: two limit behaviors appear, analogous motional narrowing inhomogeneous broadening NMR. Their crossover is found depend...
