We previously reported the development of combinations of silica aerogels and various polymer foams including polyurethane, melamine, and polypropylene (PP). These compounds show thermal conductivity ...

Airborne microplastics and nanoplastics are increasingly detected in urban environments, with evidence linking inhalation ...

Abstract: Step-index (SI) fiber designs are commonly used in achieving large mode area (LMA) and single-mode (SM) operation in fiber lasers. These fibers can either be intrinsically single-moded ...
