Comparative Evaluation of R134a and HFO‐1234ze Cryogen Spray Cooling Using a Mouse Model With Controllable Epidermal Pigmentation

Lasers in Surgery and Medicine, EarlyView.
ABSTRACT Objectives Cryogen spray cooling (CSC) is critical for protecting the epidermis during laser dermatologic procedures. The widely used cryogen, R134a, has a high global warming potential (GWP), motivating interest in environmentally favorable alternatives such as HFO‐1234ze.

Disulfide‐Induced Inhibition of Epoxy Cationic Photopolymerization: A Route to Maskless Patterning

Macromolecular Rapid Communications, EarlyView.
This study investigates the role of disulfide‐containing molecules on the photopolymerization of epoxy monomers through cationic ring‐opening reaction, with the demonstration of the selective inhibition of the polymerization when disulfides are added to the photocurable formulation. This quenching is then exploited as a novel maskless photolithographic

Automated Photothermal Control of Block Copolymer Self‑Assembly and Metal Oxide Nanostructures Sintering

Macromolecular Rapid Communications, EarlyView.
This study presents a microscope‐based photothermal platform that integrates structured laser light projection with machine‐learning‐optimized illumination. By employing neural‐network models to predict and generate thermal profiles, the platform achieves precise thermal processing of block copolymer films.

Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

Polymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...
