A Mini‐Spidroin Forms High‐Performance Artificial Spider Silk via Edge‐Cysteine–Locked β‐Sheet Assembly

Advanced Science, EarlyView.
Cysteine‐engineered mini‐spidroins (∼33 kDa) undergo phosphate‐induced liquid–liquid phase separation (LLPS), where disulfide bonds lock partially aligned polyA segments. Subsequent microfluidic spinning promotes directional β‐sheet crystallization, producing fibers with 531 MPa strength and 182 MJ/m3 toughness.

AI‐Based D‐Amino Acid Substitution for Optimizing Antimicrobial Peptides to Treat Multidrug‐Resistant Bacterial Infection

Advanced Science, EarlyView.
This study constructed the first D‐amino acid antimicrobial peptide dataset and developed an AI model for efficient screening of substitution sites, with 80% of candidate peptides showing enhanced activity. The lead peptide dR2‐1 demonstrated potent antimicrobial activity in vitro and in vivo, high stability, and low toxicity.

Luminescent Chiral Molecular Glasses by Melt‐Quenching Enantiopure BINAP

Advanced Science, EarlyView.
Melt‐quenching of enantiopure BINAP yields transparent chiral molecular glasses that retain axial chirality and display blue‐shifted luminescence together with strongly enhanced circularly polarized emission with dissymmetry factors |glum| of ≈10−2.

Vibrational circular dichroism of adenosine crystals

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy
Adenosine is one of the building blocks of nucleic acids and other biologically important molecules. Spectroscopic methods have been among the most utilized techniques to study adenosine and its derivatives. However, most of them deal with adenosine in solution.

From Solution to Surface: How the Catalytic Environment Modulates Peptide Bond Cleavage by Metal‐Oxo Cluster Nanozymes

Advanced Science, EarlyView.
Comparison of homogeneous Hf12(sol) and heterogeneous Hf12(precip) metal‐oxo clusters enables investigation of how solubility influences nanozymatic reactivity and selectivity toward proteolysis, without introducing confounding factors from differences in cluster identity.

Simultaneously Achieving Efficient Narrow‐Band Emission and Large Emission Dissymmetry Factor in an Achiral Hybrid Indium Chloride

Advanced Science, EarlyView.
This work demonstrates that efficient CPL, characterized by high PLQY, large glum, and narrow‐band emission, can be achieved simultaneously in a ligand‐modified hybrid indium chloride crystallizing in an achiral space group. ABSTRACT To achieve high contrast in three‐dimensional display, circularly polarized luminescence (CPL) materials should ...
