A Potential Function Derivation of a Constitutive Equation for Inelastic Material Response [PDF]

open access: yes, 1983
Physical and thermodynamic concepts are used to develop a potential function for application to high temperature polycrystalline material response. Inherent in the formulation is a differential relationship between the potential function and constitutive

A material model for aluminium sheet forming at elevated temperatures [PDF]

open access: yes, 2001
In order to accurately simulate the deep drawing or stretching of aluminum sheet at elevated\ud temperatures, a model is required that incorporates the temperature and strain-rate dependency of the material.\ud In this paper two models are compared: a ...

Loss of strength in Ni3Al at elevated temperatures [PDF]

open access: yes, 2006
Stress decrease above the stress peak temperature (750 K) is studied in h123i single crystals of Ni3(Al, 3 at.% Hf ). Two thermally activated deformation mechanisms are evidenced on the basis of stress relaxation and strain rate change experiments.

Slow strain rate testing of welded copper

open access: yes, 2013
In Sweden spent nuclear fuel is planned to be placed 500 m down in the bedrock. The spent nuclear fuel will be contained in copper canisters. The reason behind the selection of copper is its thermodynamic stability against corrosion in the depository. The copper will be exposed to mechanical loading and will be plastically deformed due to creep.

Analysis of Treacher Collins syndrome 4‐associated mutations in Schizosaccharomyces pombe

open access: yesFEBS Open Bio, EarlyView.
Fission yeast models carrying Treacher Collins syndrome type 4‐associated mutations reveal that impaired processivity of RNA polymerase I leads to defective rRNA transcription. This study highlights the essential role of a conserved arginine residue in Pol I elongation and provides mechanistic insight into the pathogenesis of ribosomopathies.

A New Phenomenon: Sub-Tg, Solid-State, Plasticity-Induced Bonding in Polymers

open access: yes, 2015
Polymer self-adhesion due to the interdiffusion of macromolecules has been an active area of research for several decades [70, 43, 62, 42, 72, 73, 41]. Here, we report a new phenomenon of sub-Tg, solid-state, plasticity-induced bonding; where amorphous ...

Antibiofilm activity of a chionodracine‐derived peptide by NMR‐based metabolomics of cell‐free supernatant of Acinetobacter baumannii clinical strains

open access: yesFEBS Open Bio, EarlyView.
KHS‐Cnd peptide is able to impair biofilm formation and disaggregate mature biofilms in Acinetobacter baumannii clinical isolates. Differences in extracellular metabolites reflect changes in biofilm metabolism due to KHS‐Cnd treatment. Among the differentially represented extracellular metabolites upon KHS‐Cnd treatment, the significantly altered ...

Deposition of Nickel-tungsten-phosphorus Coatings on Pure Copper in a Saline Water Environment

open access: yesInternational Journal of Electrochemical Science, 2021
Corrosion of copper caused by chloride species restricts advances in the maritime industry. In the present study, ternary Ni-W-P alloys were electrodeposited on copper in DC current mode to improve the corrosion resistance of the matrix.

Mycobacterial cell division arrest and smooth‐to‐rough envelope transition using CRISPRi‐mediated genetic repression systems

open access: yesFEBS Open Bio, EarlyView.
CRISPRI‐mediated gene silencing and phenotypic exploration in nontuberculous mycobacteria. In this Research Protocol, we describe approaches to control, monitor, and quantitatively assess CRISPRI‐mediated gene silencing in M. smegmatis and M. abscessus model organisms.

Experimental investigation on the hydrogen embrittlement characteristics and mechanism of natural gas-hydrogen transportation pipeline steels

open access: yesMaterials Research Express, 2022
Hydrogen blended with natural gas is one of the best ways for large-scale hydrogen transportation; however, pipeline steels exploited for transferring natural gas have the risk of hydrogen embrittlement.
