Facile preparation of a Ni-imidazole compound with high activity for ethylene dimerization

, 2023
A compound consisting of Ni and imidazole (Ni-imidazole) was synthesized in large quantities by a one-step co-precipitation method. The structure and stability of this Ni-imidazole were well studied by a series of characterization methods.

Self‐Assembled Crystalline Peptoid Nanomaterials as Metal‐Free Enzyme Mimics for Enhanced Carbon Dioxide Hydration and Precipitation

Advanced Functional Materials, EarlyView.
Inspired by metal‐free carbonic anhydrases (CAs) that achieve efficient catalysis without metal cofactors, we herein report a sequence‐defined supramolecular peptoid platform that mimics metal‐free CAs and exhibits hydrolytic activity via a supramolecular assembly‐mediated proton‐transfer mechanism.

Genetically Programmed Shape‐Morphing of Engineered Living Materials

Advanced Functional Materials, EarlyView.
Here, bacterial and mammalian engineered living materials (ELMs) are presented, in which living cells direct genetically programmed and enzymatically mediated shape‐morphing. The resulting deformation and shape‐recovery can be actuated in a genetically controlled manner by an ELM incorporating out‐of‐equilibrium counteracting biochemical reactions with

Utilizing the Metastability of Spidroins as a Strategy for Improving Mechanical Properties of Biomimetic Spider Silk Fibers

Advanced Functional Materials, EarlyView.
Phase transitions are central for the assembly of recombinant silk proteins into fibers. Soluble protein can transition into condensed states such as condensates and gels. These states are metastable and evolve in a time‐dependent way. Metastability depends on the protein sequence, and this relationship can be used to enhance the mechanical properties ...
