Factors influencing the working temperature of quantum dot light-emitting diodes.

Quantum dot light-emitting diodes (QLEDs) possess huge potential in display due to their outstanding optoelectronic performance; however, serve degradation during operation blocks their practical applications. High temperature is regarded as one of major factors causing degradation. Therefore, a systematical study on the working temperature of QLEDs is very essential and urgent for the development of high stable QLEDs.

SnO-Modified Two-Dimensional CuO for Enhanced Electrochemical Reduction of CO to CH.

Electrochemical reduction of CO was a widespread method for CO conversion into valuable chemical fuel. CH is an important product from CO reduction. However, conversion of CO into the hydrocarbon CH faced large energy barriers.

Construction of 1D/2D -FeO/SnO Hybrid Nanoarrays for Sub-ppm Acetone Detection.

Exhaled acetone is one of the representative biomarkers for the noninvasive diagnosis of type-1 diabetes. In this work, we have applied a facile two-step chemical bath deposition method for acetone sensors based on -FeO/SnO hybrid nanoarrays (HNAs), where one-dimensional (1D) FeOOH nanorods are in situ grown on the prefabricated 2D SnO nanosheets for on-chip construction of 1D/2D HNAs. After annealing in air, ultrafine -FeO nanorods are homogenously distributed on the surface of SnO nanosheet arrays (NSAs).

Porous GaN Submicron Rods for Gas Sensor with High Sensitivity and Excellent Stability at High Temperature.

Highly porous GaN submicron rods have been synthesized successfully by a facile hydrothermal method and heat treatment under controlled atmosphere. The morphology and size of the hydrothermal products are tailorable by adjusting the concentration of precursor solutions. Upon calcination in air, the nanorod-assembled GaOOH submicron rods are converted into bundlelike GaO and into porous GaN submicron rods under an ammonia flow.

NiO nanoparticle-decorated SnO nanosheets for ethanol sensing with enhanced moisture resistance.

In a high relative humidity (RH) environment, it is challenging for ethanol sensors to maintain a high response and excellent selectivity. Herein, tetragonal rutile SnO nanosheets decorated with NiO nanoparticles were synthesized by a two-step hydrothermal process. The NiO-decorated SnO nanosheet-based sensors displayed a significantly improved sensitivity and excellent selectivity to ethanol gas.
