Erosion by water-hammer [PDF]

open access: yesProceedings of the Royal Society of London. Series A, Containing Papers of a Mathematical and Physical Character, 1928
Abstract Corrosion or erosion of the surfaces of metals under water is in many cases found to be actively promoted by their motion through the water, or by the motion of the water over them. In such cases the relative parts played in the action by corrosion and erosion respectively are not readily distinguished.

Elastic Properties and Thermal Expansion Behavior of a Polycrystalline VMnFeCoNi High‐Entropy Alloy

open access: yesAdvanced Engineering Materials, EarlyView.
The high‐entropy alloy (HEA) V20Mn20Fe20Co20Ni20 (composition in at.%) can be made single‐phase face‐centered cubic (FCC) when annealed above 1338 K followed by water quenching. In this state, the alloy exhibits the greatest strength‐ductility combination of any quinary single‐phase FCC HEA.

Vectorized dataset of silted land formed by check dams on the Chinese Loess Plateau

open access: yesScientific Data
Check dams on the Chinese Loess Plateau (CLP) have captured billions of tons of eroded sediment, substantially reducing sediment load in the Yellow River. However, uncertainties persist regarding the precise sediment capture and the role of these dams in

Effects of Biocrusts on Hydrodynamic Characteristics of Slope Flow in Hilly Regions of Loess Plateau

open access: yesShuitu baochi tongbao, 2022
[Objective] The effects of biological soil crusts (biocrusts) on the hydrodynamic characteristics of slope flow were investigated in order to provide theoretical guidance for the study of biocrusts anti-erosive mechanism in hilly regions of the Loess ...

Superlubricity and Corrosion Inhibition Properties of Solvate Ionic Liquids in Hybrid Carbon Fiber Reinforced Plastic–Steel Interfaces

open access: yesAdvanced Engineering Materials, EarlyView.
Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...

Substantial role of check dams in sediment trapping and carbon sequestration on the Chinese Loess Plateau

open access: yesCommunications Earth & Environment, 2023
Check dams on the Chinese Loess Plateau are estimated to trap and bury approximately 10.2 ± 0.6 Pg of eroded sediment and 21.6 ± 9.9 Tg of organic carbon over the past 50 years, according to large-scale field surveys and remote sensing.

Stretching the Printability Metric in Direct‐Ink Writing with Highly Extensible Yield‐Stress Fluids

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces “drawability” as a new metric for assessing printability in direct‐ink writing, focusing on gap‐spanning performance and speed robustness. By designing yield‐stress fluids with high extensibility, we demonstrate that extensional strain‐to‐break significantly enhances printability.

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

open access: yesAdvanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

open access: yesAdvanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

Nitrogen Addition Changes the Stoichiometry and Growth Rate of Different Organs in Pinus tabuliformis Seedlings

open access: yesFrontiers in Plant Science, 2017
Background: Nitrogen (N) deposition could influence plant stoichiometry and growth rate and thus alter the structure and function of the ecosystem. However, the mechanism by which N deposition changes the stoichiometry and relative growth rate (RGR) of ...
