ATRP with ppb Concentrations of Photocatalysts
Journal of the American Chemical SocietyIn atom transfer radical polymerization (ATRP), dormant alkyl halides are intermittently activated to form growing radicals in the presence of a CuI/L/X-CuII/L (activator/deactivator) catalytic system. Recently developed very active copper complexes could decrease the catalyst concentration to ppm level. However, unavoidable radical termination results

Abstracting Asynchronous Multi-Valued Networks: An Initial Investigation [PDF]
, 2011 Multi-valued networks provide a simple yet expressive qualitative state based modelling approach for biological systems. In this paper we develop an abstraction theory for asynchronous multi-valued network models that allows the state space of a model to

3D Polymeric Nanonetworks: From Self‐Assembly to Advanced Fabrication
Macromolecular Materials and Engineering, EarlyView.This review provides the first systematic cross‐method comparison of fabrication techniques for 3D polymeric nanonetworks. It evaluates five key strategies—block copolymer self‐assembly, hyper‐crosslinking, template‐assisted methods, 3D printing, and nanolithography—across critical metrics including resolution, throughput, scalability, and material ...

Mechanophoric 3‐Arm Star Functional Block Copolymer Based on Rhodamine Derivative
Macromolecular Materials and Engineering, EarlyView.Mechanoresponsive rhodamine containing linear and star block and random copolymers were synthesized and characterized. All materials transitioned into a “switch‐on” state in the film form, but only the star block copolymer architecture exhibited a complete and precise peak shift upon stretching, providing new insights into the mechanochemical ...

Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.Diazirines are three‐membered, nitrogen‐containing heterocycles that decompose under light or heat to generate carbenes. For the past two decades, they have served mainly as minimally invasive tags in photoaffinity labeling (PAL). More recently, their value as versatile carbene precursors has been recognized.
