Effect of roughness on sequent depth in hydraulic jumps over rough bed
Građevinar, 2019 Hydraulic jump is an important phenomenon in open channel flows such as rivers and spillways. Hydraulic jump is mainly used for kinetic energy dissipation at the downstream side of a spillway with the assist of baffle blocks.

Advanced Materials, EarlyView.A 3D‐printed BSA–PEGDA bilayer actuator performs biochemical logic, bending autonomously in acid and releasing its drug payload only when both acid and pepsin are present. This dual‐stage, enzyme‐gated mechanism enables autonomous catch‐and‐release motion and controlled gastric drug delivery, representing a programmable soft material powered by ...

Impact of Anode to Cathode Crossover in Lithium‐metal Batteries With High‐Nickel Cathodes
Advanced Materials, EarlyView.Anode‐to‐cathode chemical crossover is identified as a critical degradation mechanism in lithium‐metal batteries. Full‐cell experiments with high‐Ni layered oxide cathodes and localized high‐concentration electrolytes reveal accelerated cathode impedance growth and CEI thickening driven by lithium‐metal anodes. The findings underscore the importance of

Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.This article demonstrates that encasing a hyperelastic balloon in an inextensible sleeve greatly increases its burst pressure. This simple mechanical behavior can be used to produce an asymmetric inflation‐deflation sequence for coupled balloons with different thicknesses so they could serve as a soft robot's rear and front anchors when driven from a ...

An Experimental Study of Air-water Flows in Hydraulic Jumps with Channel Bed Roughness [PDF]
, 2016 Hydraulic jumps occur naturally when supercritical flow transitions into subcritical flows in a sudden, extremely turbulent three-dimensional process. Research of hydraulic jumps is a challenge and to date turbulence and air-water flow measurements are ...
