Synthesis of Zwitterionic Tris(pyrazolyl) Ligands and Their Mn(II) Bis‐Chelates Exhibiting Charge–Transfer‐Induced Spin Crossover

European Journal of Inorganic Chemistry, EarlyView.
In this article, a series of zwitterionic scorpionate ligands based on the anionic tris‐(pyrazolyl)borate ligand scaffold is presented. These ligands are used to prepare bis‐chelates with divalent manganese ions. The resulting complexes are studied via magnetic, crystallographic, and electrochemical means to characterize the charge–transfer‐induced ...

Wide‐range and high‐resolution Young's modulus sensing enabled by a complementary indentation‐protrusion architecture

FlexMat, EarlyView.
A tactile sensor integrating indentation and protrusion sensing within a single platform enables accurate perception of object Young's modulus. This complementary architecture expands the detectable Young's modulus range to 25.8–2639.2 kPa and achieves an object recognition accuracy of 94.27%, outperforming indentation‐only (84.59%) and protrusion‐only

A Personal Perspective on Metalloprotein Structure and the Future of Macromolecular X‐Ray Crystallography

Journal of the Chinese Chemical Society, EarlyView.
While X‐ray crystallography has been the primary method for determining the structures of metalloproteins, cryoEM has taken over this role, illustrated by [4Fe4S]‐cluster containing proteins deposited in the Protein Data Bank. What will be the role for X‐ray crystallography as cryoEM and machine learning methods dominate the initial structural analysis?

Bioinorganic Site‐Specific Conjugation of Multi‐Arm Linkers to Create Pharmaceuticals With Targeting and Effector Functions

Journal of the Chinese Chemical Society, EarlyView.
This Account showcases a modular, multi‐arm linker platform that decouples payload loading from antibody conjugation. By leveraging a computationally designed ACPGHA zinc‐binding motif, we demonstrate the construction of homogeneous antibody‐drug conjugates and theranostic antibody‐radionuclide conjugates with high payload loading. The multi‐arm linker

Binuclear Copper‐Dependent Oxidative Enzymes Involved in Fungal Natural Product Modifications

Journal of the Chinese Chemical Society, EarlyView.
This article summarizes recent biochemical characterizations of a new enzyme family named by the authors as binuclear copper‐dependent oxidative enzymes (BiNCOs). Found in fungal natural product biosynthesis, BiNCOs catalyze diverse CH functionalization reactions, including C(sp3)H halogenation, C(sp3)H hydroxylation, C(sp3)O macrocyclization, and ...

Printing to Fight Antimicrobial Resistance Through Nano/Microstructured Platforms

The Chemical Record, EarlyView.
Additive manufacturing enables the rational design of structured antimicrobial platforms across multiple length scales, from nanofibrous scaffolds and droplet microreactors to 3D and 4D printed constructs. By engineering confinement, interfacial chemistry, and stimuli‐responsive release, these systems exert localized action through complementary ...
