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 ...

Self‐Assembly of Hierarchically Structured Materials From Liquid Crystalline Mesophases of Tobacco Mosaic Virus‐Like Particles

Small, EarlyView.
Recombinantly produced Tobacco Mosaic Virus coat protein (TMVcp) helical rods were demonstrated to reproducibly self‐assemble into hierarchically structured macroscopic filaments, driven by a lyotropic liquid crystal (LC) intermediate phase. The results indicate anisotropic molecular alignment of the fluid phase, retention of the native secondary ...

Colloidal Behavior of Carbonate Particles Microbially Precipitated in Microfluidic Droplets

Small, EarlyView.
In Microbially Induced Calcium Carbonate Precipitation (MICP), ureolytic bacteria trigger calcium carbonate precipitation via pH‐increasing urea hydrolysis. This enzymatically driven reaction induces the colloidal assembly of bacteria and carbonate particles into fractal networks.

Enhancing Chiroptical Selectivity and Device Stability of Chiral Perovskite Photodetectors Via Interfacial AlF3 Passivation

Small Methods, EarlyView.
An ALD‐grown AlF3 underlayer promotes grain growth, defect passivation, and improved crystalline ordering in chiral perovskite films. The resulting films exhibit enhanced chiroptical properties, superior circularly polarized light photodetector performance, and improved stability, establishing an inorganic interface‐engineering strategy broadly ...
