Evaluation and Development of a Novel Fire Barrier for Upholstered Furniture Enhancing Passive Fire Protection and the Mitigation of Chemical Exposure

Fire and Materials, Volume 50, Issue 1, Page 108-122, January/February 2026.
ABSTRACT This study evaluates the effectiveness of fire barrier solutions for upholstered furniture to enhance passive fire protection and reduce chemical exposure risks during regular use. Upholstered furniture ignition accounts for 22% of fatalities in reported home fires, often due to rapid flame spread and high heat conditions.

Techniques and Advances in Ultrafast Photography

Advanced Photonics Research, Volume 6, Issue 12, December 2025.
This review maps the fast‐growing field of ultrafast photography from early mechanical cameras to modern optical‐computational methods. It organizes techniques into four families (multishot passive/active; single‐shot passive/active), explains how they reach trillion‐frame‐per‐second speeds, compares capabilities and tradeoffs, and highlights ...
