Encapsulated Water Imparts Unprecedented Flame Retardancy to Cross-Linked Polystyrene Foams.
ACS Appl Mater Interfaces
February 2025
Water is an optimal flame retardant owing to high vaporization and specific heat, greenness and low-cost. The challenge, however, lies in how to integrate water into the matrix materials, and how to ensure its retention. To address the challenge, we developed cross-linked polystyrene foams (cPSs) that contain water within closed pores.

- This study uses a first-principles approach to explore how strain and electrostatic doping impact the electronic and magnetic characteristics of the GaN/VTe van der Waals heterostructure.
- It finds that doping with 0.1/0.2 electrostatic charge causes the magnetization to switch from out-of-plane to in-plane orientation, and examines the role of electron orbitals on magnetic properties.
- Additionally, as strain varies between -1% and 1%, the area of 100% spin polarization decreases, while a doping level of 0.1 results in a Curie temperature of 30 K above room temperature, offering insights into low-dimensional materials.
An ultraviolet-infrared (UV-IR) dual-wavelength photodetector (PD) based on a monolayer (ML) graphene/GaN heterostructure has been successfully fabricated in this work. The ML graphene was synthesized by chemical vapor deposition (CVD) and subsequently transferred onto GaN substrate using polymethylmethacrylate (PMMA). The morphological and optical properties of the as-prepared graphene and GaN were presented.
