The filtration performance of fabrics against particles of viral size: a systematic review

Wearing a mask is part of the comprehensive strategy to suppress transmission of the SARS-CoV-2 virus and respiratory tract infections. Despite available COVID-19 vaccines, wearing a mask has remained one of the simplest and most effective ways. There was, however, little data av...

Relative Effects of Fabry‐Perot, Mie, and Guided‐Mode Resonance in Periodic Photonic Lattice Physics

ABSTRACT We investigate the physical origins of resonance effects in one‐dimensional periodic photonic lattices (PhL), focusing on the relative roles of Fabry–Perot (FP), Mie, and guided‐mode resonance (GMR) mechanisms. Using rigorous numerical simulations and modal analysis, we...

Preparation and characterisation of dope‐dyed regenerated cellulose films using 1‐butyl‐3‐methylimidazolium chloride: A comparison of indigo and direct dyes

Abstract This study investigates the dissolution behaviour and dyeing performance of indigo and CI Direct Blue 1 in water, 1‐butyl‐3‐methylimidazolium chloride ([BMIM]Cl) and cellulose solutions and evaluates their effects on the properties of regenerated cellulose films (RCFs)....

Immediate changes in trunk extension and pain following a structured exercise program in high school baseball players with extension-type low back pain: a retrospective observational study

Abstract Background Extension-type low back pain (LBP) is common among baseball players, but immediate exercise responses may differ among athletes. Evidence on exercise-specific acute responses in adolescent athletes remains limited. This retrospective observational study examin...
