An Ultrapotent, Ultraeconomical, Antifreeze Polypeptide
Advanced Materials, Volume 38, Issue 4, 16 January 2026.Simple and inexpensive polypeptides composed of random copolymers of alanine and glutamic acid are effective antifreezes for applications in foods and biomedicine. The polypeptides, inspired by natural extremophile proteins, inhibit the growth of large ice crystals and prevent damage to sensitive biologics.

The first total synthesis of (+)-mucosin
, 2012 The first total synthesis of (+)-mucosin has been completed allowing assignment of the absolute stereochemistry of the natural product. A zirconium induced co-cyclisation was utilised to install the correct stereochemistry of the four contiguous ...

Botrylactone: new interest in an old moleculedreview of its absolute configuration and related compounds [PDF]
, 2010 The absolute configuration of botrylactone, a unique compound with an interesting polyketide lactone skeleton with two oxirane bridges previously isolated from Botrytis cinerea and described as a powerful antibiotic, has been reviewed on the basis of ...

Advanced Materials, Volume 37, Issue 13, April 2, 2025.Metal‐covalent organic frameworks (MCOFs) are novel porous materials that exhibit the advantages of covalent and metal‐organic frameworks. However, it is extremely difficult to resolve their atomic structure and better understand their structure‐properties relation. This work utilizes a synergistic combination of advanced microscopy, spectroscopic, and

Angewandte Chemie, EarlyView.We report herein the development of catalytic asymmetric synthesis of secondary alkyl boronates. Under the optimal conditions, Cu‐catalyzed semi‐reduction of 1‐alkyl‐ or 1,3‐dialkyl‐substituted 1‐boryl‐1,3‐butadienes forms secondary alkyl boronates with excellent regioselectivities and enantioselectivities.

Angewandte Chemie, EarlyView.We develop new bifacial chiral non‐fullerene acceptors (NFAs) for organic solar cells (OSCs). Through comparative investigations of four NFAs including meso, racemic, and chiral entries, we demonstrate the superiority of homochiral NFAs for the first time.

Hierarchical Twist: Chirality Across Scales in Cellulose Cholesterics
Advanced Optical Materials, EarlyView.Hierarchical left‐ and right‐handed chiral nematic structures are observed in a solvent‐free thermotropic cellulose derivative. Free‐standing films show hierarchical twisted structures whose pitches respond differently to uniaxial strain: left‐handed pitches increase, ones decrease.
