Vented hydrogen deflagrations in weak enclosures: experimental results and implications for industrial practice

Chemical Engineering Transactions, 2019
It is common practice in industry to install equipment for hydrogen energy applications in containers and smaller enclosures. Fires and explosions represent a significant hazard for such installations (Skjold et al., 2018), and specific measures are ...

Explosion Venting Design for a Special Vehicle

Journal of Physics: Conference Series, 2023
Abstract Explosion vents are designed for a special vehicle, via which the energy released by ammunition explosion inside the vehicle can be quickly discharged to achieve the goal of explosion venting. These vents aim to reduce the damage of shock waves generated by ammunition explosion to the special vehicle and alleviate the secondary ...

Femtosecond‐Laser Mould Texturing Enables Tunable Biointerfaces in COC Microfluidics

Advanced Materials Interfaces, EarlyView.
Femtosecond‐laser texturing of injection‐mould inserts enables scalable engineering of biointerfaces in cyclic olefin copolymer microfluidics. Replicated micro‐ and nano‐topographies modulate surface roughness and wettability, leading to texture‐dependent protein adsorption and cell adhesion without chemical post‐processing.
