Synergistic Enhancement of Modified‐PVDF Humidity Sensitivity via Chemical Adsorption‐Ionic Conductivity and its Application in Intelligent Powered Air‐Purifying Respirator

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 3, May 2026.
The study developed a PVDF/SiO2 humidity sensor with superhydrophobic properties and integrated the humidity sensor into the intelligent powered air‐purifying respirator (IPAPR) for breath monitoring. Coupled with the Gated Recurrent Unit (GRU) machine learning prediction algorithm, it enables feedforward control of the fan to achieve respiratory ...

Why Is MS a More Frequent Complication of EBV Infection in Females?

Immunological Reviews, Volume 339, Issue 1, May 2026.
ABSTRACT Multiple sclerosis (MS) is a T helper (Th) cell‐mediated disease that targets central nervous system (CNS) white matter. This disease affects three times more females than males. For many years, the etiology of MS was not well understood and the exact nature of the autoimmune reaction was speculative.
