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 ...

Assessing Deposit‐Derived Pyroclastic Flow Hazard at Stromboli (Italy): 1. Reconstruction of the Dynamics of the 11 September 1930 Event

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract Stromboli volcano (Italy) is known for its persistent explosive activity punctuated by more energetic explosions called paroxysms. During paroxysms, pyroclastic density currents, triggered by the gravitational instability of hot pyroclastic deposits, can occur.

Propagation law of gas-coal dust explosion shock waves under different explosion conditions

Gong-kuang zidonghua
To address the limitations of current experimental and numerical studies on the propagation of gas-coal dust explosion shock waves, which are mostly confined to small-scale laboratory pipelines or local roadways, this study adopted a segmented relay ...

Investigation of the suppression effect of inert dust on the pressure characteristics of gas coal dust explosion

Thermal Science
The suppression effect of inert powder on gas-induced suspension coal dust explosions was investigated using a semi-closed pipeline experimental platform. The shock wave overpressure propagation characteristics of gas explosions with different concentrations of mixed dust (calcium carbonate and coal dust) were measured and analyzed.

Mountain‐top spherules: Criteria to identify natural and synthetic particles

Meteoritics &Planetary Science, Volume 61, Issue 5, Page 898-913, May 2026.
Abstract Natural microspherules are important tracers of geologic and environmental processes in modern and ancient deposits. However, anthropogenic contamination can dilute natural collections by releasing synthetic microspherules into the environment.

Turbulent Flames Speeds and Laminar Burning Velocities of Dusts using the ISO 1 m³ Dust Explosion Method

Chemical Engineering Transactions, 2014
The ISO 1 m3 dust explosion vessel was instrumented with thermocouples acting as flame detectors. These were used with methane/air gas explosions to show that the explosion flame was spherical in the constant pressure phase of the explosion and that a ...
