Sulfur defect and Fe(III) (hydr)oxides on pyrite surface mediate tylosin adsorption in lake water: effect of solution ch...

Published in Environmental science and pollution research international

Pyrite affects the adsorption of tylosin (TYL) due to their coexistence in the lake system. As well as the reactivity groups of S-S-H, S-OH, and Fe-OH, defects also have the possibilities to influence the adsorption of organic contaminants. However, the role of these active sites in antibiotic adsorption on pyrite has not been deeply studied. Besid...

Electronic and thermal signatures of phosphorene grain boundaries under uniaxial strain

Two-dimensional materials have great potential for applications as high-performance electronic devices and efficient thermal rectificators. Among them, pristine phosphorene, a single layer of black phosphorus, has shown promising properties such as ultrahigh charge mobility, a tunable band gap, and mechanical flexibility. However, the introduction ...

Predictive model to design for high cycle fatigue of stainless steels produced by metal additive manufacturing.

Published in Heliyon

This work develops a predictive model of S-N curves capable of proving the lower and upper bounds for fatigue behaviour of parts fabricated using different metal laser-based additive manufacturing (AM) and post-processing technologies. Alongside the ultimate strength of the material and its endurance limit, a surface factor and a defect factor are ...

Recent Progress in Surface and Interface Engineering for Electrocatalytic CO2 Reduction.

Published in Chemistry, an Asian journal

The conversion of CO2 through CO2 reduction reaction(CO2 RR) into valuable products has potential to lessen the greenhouse effect caused by uncontrolled CO2 emissions. Challengesof CO2 RR reaction lie in the stabilization of the reaction intermediate and theactivation of the inert chemical bond of CO2 ,but the application of CO2 RR at large scale i...

Electron-spin spectral diffusion in an erbium doped crystal at millikelvin temperatures

Erbium doped crystals offer a versatile platform for hybrid quantum devices because they combine magnetically sensitive electron-spin transitions with telecom-wavelength optical transitions. At the high doping concentrations necessary for many quantum applications, however, strong magnetic interactions of the electron-spin bath lead to excess spect...

Multidentate Chelation Heals Structural Imperfections for Minimized Recombination Loss in Lead-Free Perovskite Solar Cel...

Published in Angewandte Chemie (International ed. in English)

Tin-based perovskite solar cells (Sn-PSCs) have emerged as promising environmentally viable photovoltaic technologies, but still suffer from severe non-radiative recombination loss due to the presence of abundant deep-level defects in the perovskite film and under-optimized carrier dynamics throughout the device. Herein, we healed the structural im...

Plasma-enabled synthesis of Pd/GO rich in oxygen-containing groups and defects for highly efficient 4-nitrophenol reduct...

Effective catalytic removal of 4-nitrophenol (4-NP) in industrial wastewater remains a significant challenge due to the lack of highly efficient and stable catalysts. Herein, we demonstrated a promising plasma method for the facile, ultra-fast and low-temperature synthesis of graphite oxide (GO)-supported palladium catalyst (Pd/GO-P) rich in oxygen...

Etude de la relaxation de contraintes dans la dégradation spontanée des couches d'InAIN par les calculs atomistiques des...

Parmi les alliages de nitrures III-V, l'InAlN a suscité un grand intérêt technologique ces dernières années en raison de sa large bande interdite et de sa concordance de réseau avec le GaN à une composition d'indium de 18%, avec comme application une meilleure barrière pour la prochaine génération de transistors à haute mobilité électronique (HEMT)...
