Synthesis and Isolation of Bismuth Scorpionate Complexes: Toward Bond Activation via Bismuth‐Ligand Cooperation

open access: yesChemistry – A European Journal, EarlyView.
ABSTRACT Over the past twenty years, main group chemistry has significantly expanded its scope to include reactivities once considered the exclusive domain of transition metals. Among the emerging concepts, element‐ligand cooperation has proven to be a powerful strategy for enabling bond activation reactions but remains relatively unexplored for ...

One‐Pot Transition‐Metal‐Free Methods for the Synthesis of All Three Bonds of the Alkyne's Triple Bond

open access: yesChemistry – A European Journal, EarlyView.
One‐pot transition‐metal‐free methods for the synthesis of all three bonds of the alkyne's triple bond are reviewed. After analysis of several named reactions and discussion of improvements, recent advances in the synthesis of alkynes are discussed. Each section contains a proposed reaction mechanism and analysis of the strengths and weaknesses of the ...

Single GAF Domain Phytochrome Exhibits a pH‐Dependent Shunt on the Millisecond Timescale

open access: yesChemPhysChem, Volume 26, Issue 6, March 15, 2025.
During their light‐induced photocycle, phytochromes can engage in a thermal reversion back to the initially excited state, denoted as a shunt. This study investigates a pH‐dependent shunt transition in the Pfr state of the All2699g1 phytochrome from Nostoc punctiforme using UV/Vis laser flash photolysis and kinetic modeling. The findings suggest a keto‐

The Role of Social Media in Exposing Greenwashing: Consumer Sentiments and Discussions

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study examines consumer responses to greenwashing on social media, with a focus on X (formerly Twitter), where exaggerated or deceptive environmental claims are subject to heightened public scrutiny. As sustainability becomes a pressing concern, consumers are increasingly holding companies accountable for their environmental messaging ...

Bridging Theory and Prediction: A Hybrid SEM and Machine Learning Approach to Optimize Lean Construction for Megaproject Sustainability in China

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Construction megaprojects, large‐scale, complex, and capital‐intensive, are particularly prone to inefficiencies, cost overruns, delays, and environmental degradation due to fragmented workflows, stakeholder misalignment, and resource intensity.
