Steric‐Guided Coordination Engineering Enables Significantly Optimized Optical Anisotropy via Sulfur‐Driven [C5H5NS] Birefringence‐Active Groups

Small, EarlyView.
Four mercaptopyridine (MP)‐based anisotropic crystals, (4‐MP)2HgCl2 (I), (4‐MP)HgCl2 (II), (2‐MP)HgCl2 (III), and [(2‐MP)HgCl]2·HgCl2·2Cl (IV), were rationally designed to elucidate coordination‐regulated optical anisotropy. Through a steric‐guided coordination engineering strategy, stoichiometric modulation of n2‐/4−MP:nHg [2:1 (I) → 2:2 (II) → 2:2 ...

Electrochemical and Biological Evaluation of Patterned TiO2@TiC‐Nanowires for Bio‐Interface Electrode

Small, EarlyView.
This study introduces a room‐temperature process to fabricate patterned TiO2@TiC core–shell nanowires, merging the biocompatibility of TiO2‐NWs with the high conductivity of TiC. Through sputtering pressure and time modulation, the nanowires morphology and electrochemical properties are tuned, enabling enhanced capacitance, stability, and guided ...
