Sulfur‐Rich Sustainable Copolymers for Enhancing Redox Kinetics and Alleviating Cathode Passivation in Lithium‐Sulfur Batteries

open access: yesExploration, EarlyView.
A molecularly engineered, sustainable sulfur‐rich redox copolymer cathode delivers accelerated sulfur conversion and suppressed passivation, enabling high sulfur utilization and durable, high‐performance LiS batteries. ABSTRACT Lithium‐sulfur (Li‐S) batteries are promising candidates for advanced energy storage systems.

Strengthened inter‐chain π–π contacts in amorphous diketopyrrolopyrrole polymers for robust flexible organic thin‐film transistors

open access: yesFlexMat, EarlyView.
Vinylene‐linked DPP polymers with expanded thiophene donors achieve strengthened interchain π‐π stacking in near‐amorphous films, enabling high charge mobility and outstanding mechanical stability for flexible organic thin‐film transistors. Abstract Flexible organic thin‐film transistors (OTFTs) based on multi‐vinylene‐linked diketopyrrolopyrrole (DPP)

Reverse evolution of fluorine and side chains in bisisoindigo‐based copolymers enabling electron mobility exceeding 7 cm2·V−1·s−1

open access: yesFlexMat, EarlyView.
Abstract We report the design and synthesis of a series of bisisoindigo‐based donor–acceptor (D–A) copolymers, P4F18, P4F10, P2F18, and P2F10. By reverse evolution of fluorine substitution and side‐chain structure, we effectively tuned the frontier molecular orbital energy levels, intermolecular interactions, molecular self‐assembly, and thus charge ...

Polymer informatics: Integrating data‐driven strategies, advanced machine learning, and automated synthesis for next‐generation polymer design

open access: yesInfoScience, EarlyView.
Designing new polymers for applications such as sustainable plastics, biomaterials, and 3D printing has traditionally been slow and expensive, relying heavily on trial‐and‐error experiments. This review shows how polymer informatics—the integration of large polymer databases, machine‐learning models, and automated robotic synthesis—enables fast ...

Bayesian optimization enables balanced ambipolar transport in self‐doped random conjugated polymers

open access: yesInfoMat, EarlyView.
The integration of side‐chain self‐doping with Bayesian optimization enables balanced ambipolar transport in random conjugated polymers with only six experiments, establishing a general and efficient paradigm for the rational design of flexible electronic materials.

The Molecular Weight Characterisation of Pinus radiata Bark Condensed Tannins

open access: yes, 2007
Crude condensed tannins extracted from Pinus radiata bark (sourced from Tokoroa) with various solvents (Hot water (HW), methanol/water/acetic acid (MWA), acetone/water (AW) and hot aqueous 2% sulphite/urea solution (SFU)) were subjected to Sephadex LH-20

Half a Century of Per‐ and Polyfluoroalkyl Substances in Northern Gannet Eggs: Impact of Regulations

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Per‐ and polyfluoroalkyl substances (PFAS), known as “forever chemicals”, are persistent organic pollutants that have been widely used in the industry across the globe for many decades. Their chemical stability, bioaccumulation, and toxicity pose major environmental and health risks. This study examines temporal trends in the concentrations of
