ON EROSION PROCESS OF COHESIVE SEDIMENT AND EROSION RATE FORMULA

PROCEEDINGS OF HYDRAULIC ENGINEERING, 2003
Erosion process of soft cohesive material which deposited naturally on a river bed is the objective of the present paper. Extensive series of experiments, the condition of which were set systematically, were conducted to evaluate the erosion rate by running water in a closed conduit. The test sample was the mixture of silica sand. clay and water.

Functionalizing Micro‐to‐Mesoscopic Electrode Architectures for Regulating Electron Transfer Behaviors in Electrocatalysis

Advanced Functional Materials, EarlyView.
A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

Meniscus‐Guided Soft‐Lithographic Assembly of Grid‐Type Molecular Martensite Films for Single‐Crystal‐Like Actuation

Advanced Functional Materials, EarlyView.
A meniscus‐guided microtransfer molding strategy enables scalable fabrication of grid‐type molecular martensite films with b‐axis‐correlated preferential texture. Sequential growth across microchannel intersections creates structurally continuous grids and robust thermoelastic actuation (∼11% strain, > 50 cycles, maximum force density: 7.1 × 109 N m−3).
