Defect spectroscopy of single ZnO microwires [PDF]

open access: yes, 2014
The point defects of single ZnO microwires grown by carbothermal reduction were studied by microphotoluminescence, photoresistance excitation spectra, and resistance as a function of the temperature.

Polyethylene Terephthalate Monomerization via Glycolysis and Methanolysis Using Metal‐Free Basic Carbocatalyst

open access: yesChemCatChem, Volume 18, Issue 3, 12 February 2026.
The image represents a sustainable solution via chemical recycling of waste PET bottle‐to‐rPET bottle via monomerization process (glycolysis and methanolysis) in the presence of metal‐free basic carbocatalyst. Abstract The giant amount of disposed Polyethylene Terephthalate (PET) has become a big environmental challenge.

Exploring the Parameter Space of Colloidal High‐Entropy Alloy Synthesis Methods

open access: yesChemistryEurope, Volume 4, Issue 2, February 2026.
We present a systematic study of the parameter space of a simple colloidal synthesis method in which high‐entropy alloy (HEA) nanoparticles (NPs) are formed in triethylene glycol. Ultra‐small (1‐3 nm), single‐phase HEA nanoparticles are obtained via a hot‐injection approach.

Development of Suppressed Ion Chromatography for the Online Quantification of Cations in Electrochemical Ammonia Synthesis Research

open access: yesChemSusChem, Volume 19, Issue 3, February 2026.
We developed a suppressed ion chromatography method with automated matrix neutralization and matrix elimination for the quantitative determination of ammonium in electrochemical ammonia synthesis research. Online determination of ammonium in 0.2 M sulfuric acid electrolyte revealed Nafion ionomer as a non‐negligible secondary source of ammonium ...

Extraction of magnesium from garnierite by carbothermal reduction in vacuum

open access: yesMaterials Research Express, 2020
The aim of the traditional pyrometallurgical processes is to extract nickel and iron in garnierite, but it is difficult to extract magnesium of higher value in minerals.

Kinetics of carbothermic reduction of synthetic chromite

open access: yesJournal of Mining and Metallurgy, Section B: Metallurgy, 2014
In order to optimize the current reduction process of chromite, a good knowledge of reduction mechanism involved is required. The basic component in chromite ore is FeCr2O4, thus, kinetic investigation of synthetic FeCr2O4 with different amount of carbon were carried out in the temperature range of 1473K to 1673K under both isothermal and ...

Designing with Li2S in Lithium–Sulfur Batteries: From Fundamental Chemistry to Practical Architectures

open access: yesSmall, Volume 22, Issue 9, 12 February 2026.
This perspective highlights the design evolution of Li2S‐based lithium‐batteries, illustrating sulfur redox chemistry and Li2S activation. Emphasis is placed on catalytic interfaces, hierarchical carbon frameworks, and electrolyte‐solvation co‐design, enabling lithium‐free, anode‐free, and solid‐state Li‐S architectures for high‐energy, manufacturable ...
