Tracking Climate and Environmental Attention: A News‐Based Composite Index

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study introduces the Climate and Environmental Attention Index, a composite indicator that tracks media attention to climate and environmental issues. Based on the Semantic Brand Score, the proposed index extracts significant signals from unstructured text, going beyond traditional measures of word frequency and sentiment.

Effect of Reaction Time and Temperature on the Impurity Profile of Amphetamine in the Leuckart Method

open access: yesDrug Testing and Analysis, EarlyView.
This study investigates the effect of the reaction temperature (step 1) and reaction time (step 1 and 2) on the conversion efficiency and impurity profile of amphetamine synthesized via the Leuckart method. Conversion efficiency and impurity profile were assessed using gas chromatography–flame ionization detection (GC–FID) and GC–mass spectrometry (GC ...

Electronic Synergy in NiCo‐Embedded Nitrogen‐Doped Hollow Mesoporous Carbon Spheres for Bifunctional Oxygen Catalysis and Zinc–Air Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study employs a hard‐templating etching strategy to synthesize N‐doped hollow mesoporous carbon spheres embedded with NiCo nanoparticles (denoted as NiCo@N‐HMCS). The optimized catalyst exhibits exceptional bifunctional catalytic activity for the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER) in alkaline media, achieving a ...
