Prediction of the Reduced Explosion Pressure During Vented Gas Explosions Using a One-Dimensional Combustion Model in Combination with the Efflux Function

Chemical Engineering Transactions, 2019
Pressure venting is a common method in process industry to limit the overpressure during a gas phase explosion to the design pressure of a vessel. The ability to predict the reduced explosion pressure for a given vent area is crucial in the design of ...

Thermally Pre‐Formed Reconfigurable Resistive Random‐Access Memory Crossbar Arrays: A Dual‐Mode Platform for Robust Physically Unclonable Functions and In‐Memory Computing

Advanced Functional Materials, EarlyView.
A reconfigurable RRAM platform utilizing thermally pre‐formed filaments (TPFs) is developed to realize robust hardware security. By exploiting the thermodynamic stochasticity of TPFs, exceptionally reliable physically unclonable functions (PUFs) are achieved.

Experimental Study of Explosion Limits of Refrigerants and Lubricants’ Mixture

, 2012
The explosion limits of refrigerants and lubricants’ mixture were studied. The refrigerants like R161, R1234yf and R152a are combustible. Lubricants, to a certain extent, are combustion-supporting.

Experimental investigation of p-section concrete beams under contact explosion and close-in explosion conditions

Defence Technology, 2018
This paper presents the results of an experimental investigation on explosive breaching of p-section concrete beams. Twenty three p-section concrete beams with a 100 cm length were tested. TNT charges were placed at three positions: contact detonation in

Shape Memory Microneedle to Prevent Risks of Reproductive Hormone Therapy by Switching Sustained to Burst Release Under a Single Transdermal Insertion

Advanced Functional Materials, EarlyView.
A shape‐memory microneedle system enables reproductive hormone therapy through a single transdermal insertion. The X‐shaped device sustains follicle‐stimulating hormone release for three days, and mild heating restores the O shape to trigger burst human chorionic gonadotropin release.

Design of a LED-based sensor for monitoring the lower explosion limit of methane

, 2022
S.930-939Here we present the development of a gas sensor system for the monitoring of the lower explosion limit (LEL) of methane. A mid-infrared light emitting diode (LED) with central emission wavelength of 3.4mm is used as light source to probe the n3 ...

Shaping Matter with Acoustic Waves: From Particles to Functional Structures

Advanced Functional Materials, EarlyView.
Acoustic‐directed assembly is reviewed as a materials‐oriented strategy for organizing particles, polymers, metals, and biological systems into functional structures. The review distinguishes reversible manipulation from permanent structure formation through medium fixation, particle fixation, and in situ material generation, highlighting routes toward
