Size and Polarizability as Design Principles for Stereoselective Catalysis

open access: yesChemistry – A European Journal, Volume 31, Issue 68, December 4, 2025.
In recent years, noncovalent interactions (NCIs) have been recognized as a key component in substrate activation and control in stereoselective catalysis. We demonstrate that size and polarizability serve as powerful, yet simple descriptors for catalyst and substrate design on a quantitative level.

Application of Crosslinked Epoxy‐Based Gel Polymer Electrolytes for Li‐Ion Battery

open access: yesMacromolecular Materials and Engineering, Volume 310, Issue 12, December 2025.
Crosslinked gel polymer electrolytes are prepared using epoxidized soybean oil (ESO) and bisphenol A diglycidyl ether (DGBEA). The resulting polymer electrolytes exhibited a wide electrochemical stability window (up to 4.2 V), ionic conductivity in the range of 10−4 S cm−1, and a cation transference number between 0.47 and 0.76.
