Co‐Cu Materials Library Screening for Discovering Electrocatalysts for the Co‐Reduction of CO2 and Nitrate to Urea

ChemistryEurope, EarlyView.
Scanning electrochemical cell microscopy on multimetal materials libraries is used for the high‐throughput investigation of element composition‐dependent electrocatalytic activity for the coreduction of CO2 and NO3−. Combined with selectivity analysis from electrolyzer experiments of promising catalyst compositions introduces a catalyst design strategy

Chemical Methods for Peptide and Protein Backbone Cleavage

ChemistryEurope, EarlyView.
Protein cleavage plays essential roles in biology and is powerful for protein manipulation and functionalization as well as in recombinant expression and purification. Here, the historical background and most recent examples of chemical methods for protein and peptide backbone cleavage are discussed (part of the figure was generated in BioRender).

Defect Suppression via Tailoring Functionalized Additives for Efficient and Stable CsPbI3 Perovskite Solar Cells

Carbon Energy, EarlyView.
This study proposed a structure‐designed benzohydrazide derivative, namely 4‐methoxybenzohydrazide (MeOBH), as an additive to regulate crystallization, passivate defects, optimize energy‐level structure, and enhance phase stability of β‐CsPbI3 perovskite films.

Expanding the Toolbox for Inducible Protein Expression With Automation‐enabled Generation of Glycomimetics

Chemistry – A European Journal, EarlyView.
Inducible protein expression is a cornerstone of many aspects of industrial and molecular biotechnological processes. 2′‐fucosyl isopropyl‐β‐D‐thiogalactopyranose (2′F‐IPTG) and 2′‐fucosyl isobutyl‐C‐galactoside (2′F‐IBCG) mimics were explored for protein expression studies.

Shedding Light on Synthetic Autocatalysis: From Conventional Closed‐Shell Chemistries to Overlooked Open‐Shell Occurrences

Chemistry – A European Journal, EarlyView.
Why add another catalyst when the product itself holds the power to catalyze its own formation? Autocatalysis in synthetic chemistry enhances reaction efficiency and uncovers novel catalytic behavior across both closed‐shell and open‐shell systems, expanding reactivity and enabling innovative design strategies.
