Bio‐Based Polyurethanes: Mechanical Performance, Structure–Property Relationships, and Future Directions

Journal of Polymer Science, EarlyView.
This review examines bio‐based polyurethanes from renewable feedstocks, focusing on structure‐property relationships governing mechanical performance. It analyzes reinforcement strategies, benchmarks against petrochemical counterparts, and explores future directions, including non‐isocyanate routes and circular economy integration for sustainable high ...

Mechanically Triggered Chemical Recyclable Polyethylene‐Like Materials

Angewandte Chemie, Volume 138, Issue 11, 9 March 2026.
Polyethylene‐like copolymers with benchmark properties are prepared by embedding latent cyclobutene mechanophores to overcome PE's end‐of‐life limits. The mechanophores are inert in service but are selectively opened by solvent‐free ball milling to yield well‐defined telechelic oligomers.

Living Coordination (Co)Polymerization of Norbornene Derivatives by Using Nickel Catalysts Derived From Bis(1,5‐Cyclooctadiene)nickel(0) and 2,6‐Dihydroxybenzoic Acid

Journal of Polymer Science, EarlyView.
The living coordination polymerization of norbornene is achieved using a nickel catalyst derived from Ni(cod)2 and 2,6‐dihydroxybenzoic acid with trityl borate as cocatalyst to produce poly(norbornene) with controllable molecular weights and narrow polydispersity.

University teaching of mass spectrometry as a key practical technique within the context of a fully integrated, spiral curriculum

Rapid Communications in Mass Spectrometry, EarlyView.
Rationale Mass spectrometry (MS) is introduced to high school students in the UK in many pre‐university course syllabi. As such, we have identified the use of MS as a key technique that should be taught practically to undergraduates from the outset of their studies.

C-Glycosidic Genistein Conjugates and Their Antiproliferative Activity

Journal of Chemistry, 2013
This paper presents our attempt to investigate scopes and the limitations of olefin cross-metathesis (CM) reaction in the synthesis of complex C-glycosides of genistein and evaluation of their antiproliferative activities. Novel genistein glycoconjugates

A Liquid Ge(IV) Precursor for Low Temperature Plasma Enhanced Atomic Layer Deposition of Germanium Oxide Thin Films

Small, EarlyView.
Utilizing the 3‐(N,N‐dimethylamino)propyl (DMP) ligand, the new liquid Ge(IV) precursor [Ge(DMP)4] has been developed, which possesses adequate volatility, reactivity, and exceptional thermal stability. This precursor is capable of low‐temperature processing of GeO2 and GeOx with tunable film composition and sub‐nm thickness control in a range from 40 ...
