Domino Polymerization for the Synthesis of Reductively Degradable Poly(disulfide)s With Arbitrary Side‐Chain Structures

Angewandte Chemie, EarlyView.
We developed a novel domino polymerization to synthesize reductively degradable poly(disulfide)s with tunable side chains. A novel monomer bearing thiolactone and pyridyl disulfide groups reacts with various amines, enabling continuous ring‐opening and disulfide exchange.

Cell Cycle‐Specific Regulation of Centrosome Clustering Dynamics in Cancer Cells by the Multifunctional Kinesin HSET

Advanced Science, EarlyView.
CDK5RAP2 associates with the kinesin HSET and forms co‐condensates. HSET motors drive the directional transport of CDK5RAP2 condensates toward microtubule minus ends. During mitosis, HSET self‐assembly further stabilizes clustered centrosomes, thereby enabling pseudo‐bipolar spindle formation in cancer cells with supernumerary centrosomes. Upon mitotic

Directed Evolution of an Efficient Polycarbonate Depolymerase With Exceptional Operational Stability

Angewandte Chemie, EarlyView.
Here, we show that well studied PET hydrolases can be re‐engineered via directed evolution to deconstruct alternative aromatic‐containing commodity polymers. Introduction of only three mutations into LCCICCG was sufficient to generate an efficient polycarbonate hydrolase with high operational stability that can fully depolymerize a polycarbonate sample

Wood‐Based Bioelectronics: Lignosulfonate‐Based Conductive Biocomposites for Paper Organic Electrochemical Transistors

Advanced Electronic Materials, EarlyView.
Biodegradable wood‐based bioelectronics are realized by integrating poly (2,3‐ethylenedioxythiopene:lignosulfonate (PEDOT:LigS) as a mixed ionicelectronic channel in organic electrochemical transistors fabricated on paper substrates. The biocomposite exhibits high conductivity, biocompatibility, and strong transistor performance, while devices built on

Toward a Rational Design of Conjugated Copolymers with Oxygenated Side Chains for Boosting Thermoelectric Properties

Advanced Energy Materials, EarlyView.
The molecular design strategy that integrates both side chain and backbone engineering in diketopyrrolopyrrole‐based conjugated polymers to identify the optimal balance between doping efficiency and microstructural order is demonstrated. Comprehensive spectroscopic, electrochemical, morphological, and structural characterizations reveal that the ...
