Efficacy and Safety of Small‐Spot 755 nm Picosecond Laser‐Induced Optical Breakdown for Novel Photomechanical Skin Ablation in Asian Patients

Lasers in Surgery and Medicine, EarlyView.
ABSTRACT Objectives Conventional ablative and photothermal lasers are commonly used to treat superficial pigmentary lesions but often induce thermal injury and post‐inflammatory hyperpigmentation (PIH), particularly in Asian skin. Picosecond 755‐nm alexandrite lasers with diffractive lens arrays (DLA) create laser‐induced optical breakdown (LIOB ...

High‐Temperature Corrosion of Unpassivated Carbon Steel in Simulated Boiler Water: Electrochemical Thresholds and Mechanisms for Chloride and Sulphate Contamination

Materials and Corrosion, EarlyView.
Through a combination of in situ electrochemical corrosion rate measurements and FactSage thermochemistry modeling, chloride and sulphate ions were found to influence the corrosion of carbon steel in high‐temperature boiler water through distinct mechanisms: chloride acidifies the solution, raising iron solubility, while sulphate leaves solubility ...

Exploring biofiber properties and their influence on biocomposite tensile properties

Polymer International, EarlyView.
The study measured the physical, flow and chemical properties of 10 biofibers. It characterized the tensile properties of derived biocomposites and linked them using regression models, showing robust predictive performance. Abstract Biofibers serve as effective reinforcements for neat polylactic acid (PLA) in biocomposites, offering an attractive ...
