Blast tube design: How shape and size influence the resultant shock wave
AIP AdvancesShock tubes and tunnels are often used in research settings as a way of producing high pressure shock waves in a smaller footprint or without the use of explosives. However, there is no standard geometric design across laboratories.

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.

Effect of the Spudcan’s Footprints on Nearby Jacket’s Mudmat in Clayey Soil-Case Study
International Journal of Maritime Technology, 2016 When a jack-up installed at a clay location and then leaves; it can create several meter deep footprints. In case of soft clay, the spudcan may have actually penetrated much deeper than the observed footprints.

Advanced Materials Technologies, EarlyView.Parallel wiring of bioelectrochemical devices with conventional generators unexpectedly boosts output. A biophotovoltaic paired with a solar cell delivers up to 50% more power at low loads than their separate contributions; a plant microbial fuel cell shows similar current gains.
