Phosphazene Base Mediated (sp3)C–H Functionalization with CO2 and CS2

European Journal of Inorganic Chemistry, Accepted Article.
The activation of weakly acidic (sp³)C–H bonds in substrates such as fluoroform (HCF3), perfluoroethane (HC2F5), and acetonitrile (H3CCN) remains a fundamental challenge in synthetic chemistry. We report that the phosphazene base {(Et2N)3P=N}3P=NtBu (EtP4) enables the selective deprotonation of these molecules when combined with electrophilic small ...

Cross‐Coupling Reactions in Aqueous Micellar Media

European Journal of Organic Chemistry, Accepted Article.
Thanks to their ability to efficiently and reliably construct carbon‐carbon and carbon‐heteroatom bonds, cross‐coupling reactions remain at the forefront of chemical research in both academic and industrial settings. However, the growing emphasis on sustainability has exposed the shortcomings of cross‐coupling chemistry in several areas, including the ...

Impact of Deposition Temperature on the Performance of Sputtered SnO2 Electron Transport Layer in Perovskite Solar Cells

Energy Technology, EarlyView.
Sputtering, an industrial technique, is demonstrated to be viable for fabricating SnO2 electron transport layer for the emerging perovskite solar cell (PSC) technology. This study finds that a deposition temperature of 100 °C during sputtering of SnO2 results in the best film, leading to high‐performance PSCs.

Effects of temperature on biofilm formation and resource recovery during anoxyphototrophic treatment of fuel‐synthesis wastewater

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND Fuel‐synthesis wastewater (FSW), a byproduct of the Fischer‐Tropsch process, requiring efficient treatment and resource recovery strategies. This study aimed to optimize temperature conditions for purple non‐sulfur bacteria (PNSB) biofilm formation and bioproduct recovery while simultaneously treating FSW. Experiments were conducted

Raman Study of the Slobodka Ordinary Chondrite

Journal of Raman Spectroscopy, EarlyView.
The texture and mineral chemistry of Slobodka are most consistent with L4 chondrites, exhibiting strong shock metamorphism characteristic of shock stage S4, including irregular and planar fractures, undulatory extinction, and mosaicism in olivine, pyroxene, and plagioclase.

Adsorbable and Antimicrobial Amphiphilic Block Copolymers with Enhanced Biocompatibility

Macromolecular Materials and Engineering, EarlyView.
Permanently implanted biomaterials are prone to attract microorganisms and thus represent niches for infections in vivo. Absorbable, antimicrobial polymers have emerged as a promising option. To improve the compatibility of adsorbable antimicrobial polymers with human cells, the block composition of the polycationic segment is modified regarding the ...
