Defect engineering for highly efficient and stable perovskite top cells for Si tandems

Bulletin of the Korean Chemical Society, EarlyView.
Defect passivation in wide‐bandgap perovskites is essential for enabling high‐efficiency and stable perovskite/Si tandem solar cells. Bulk, surface, and buried‐interface passivation strategies focus on suppressing nonradiative recombination, ion migration, and halide segregation, thereby clarifying critical design principles for next‐generation tandem ...

Mechanistic elucidation of HFIP‐enabled C–Cl bond activation in the synthesis of tetrahydroquinoline derivatives

Bulletin of the Korean Chemical Society, EarlyView.
Mechanistic studies reveal that hexafluoroisopropanol (HFIP) enables C–Cl activation of propargylic halides by stabilizing ion pairs and enhancing effective Brønsted acidity. This cooperative solvent effect allows access to cationic intermediates and promotes cascade formation of tetrahydroquinolines through cyclization and disproportionation ...

Ecology and evolution of pyrazines in insects

Biological Reviews, EarlyView.
ABSTRACT Chemical communication is the oldest and most widespread form of signalling among and within organisms. Among the many compounds involved in such communication, pyrazines – nitrogen‐containing heterocyclic molecules – are especially intriguing due to their widespread occurrence across the tree of life, from bacteria and fungi to insects and ...

Protein hydrolysates in cell culture: Toward multi‐omics characterization

Biotechnology Progress, EarlyView.
While protein hydrolysates are widely used in cell culture applications, they remain undefined and variable products. Multi‐omic characterization evaluating composition and function can transition hydrolysates toward semi‐defined media components.

Multifunctional Design of Solid Polymer Electrolytes: Paving the Way for High‐Performance All‐Solid‐State Batteries

Carbon Energy, EarlyView.
This review provides a comprehensive and systematic overview of the multifunctional design strategies for solid polymer electrolytes (SPEs), a pivotal component for enabling high‐performance all‐solid‐state batteries (ASSBs). It begins with a detailed classification of SPE systems and elaborates on their respective molecular design principles. The work
