Strain hardenability of a gradient metallic alloy under high-strain-rate compressive loading

Materials & Design, 2019
Subjected to an impact loading, metallic alloys usually display strain softening due to the highly localized shear deformation accompanied by temperature rise, which causes the decrease of resistance to an applied loading and even catastrophic failure ...

Some aspects on geometric and matrix work-hardening characteristics of sintered cold forged copper alloy preforms [PDF]

Materials Research, 2013
Powder metallurgy (P/M) material subjected to plastic deformation results into densification, however the extended deformation would not only enhance the densification also supplements the strain hardening.

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

FEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Beyond necking - Novel characterisation method to investigate the tensile response of sheet metals at elevated temperatures and constant true strain rates

Advances in Industrial and Manufacturing Engineering
Characterisation of the strain hardening behaviour for metal forming simulations at elevated temperatures still poses a challenge for state of the art characterisation strategies, where often microstructural changes shall be investigated simultaneously ...

Study of the tensile behavior of AISI type 316 stainless steel using acoustic emission and infrared thermography techniques

Journal of Materials Research and Technology, 2015
Acoustic emission (AE) and infrared thermography technique (IRT) have been used to study the tensile behavior of AISI type 316 stainless steel. Strain rates of tensile testing were varied from 1.4 × 10−3 s−1 to 1.4 × 10−2 s−1. AE root mean square voltage

Modelling of behaviour of metals at high strain rates [PDF]

, 2006
The aim of the work presented in this thesis was to produce the improvement of the existing simulation tools used for the analysis of materials and structures, which are dynamically loaded and subjected to the different levels of temperatures and strain ...

Screening and epitope characterization of Nidogen‐2‐specific nanobodies

FEBS Open Bio, EarlyView.
Camel immunization and phage display were employed to generate high‐affinity VHH nanobodies against Nidogen‐2. After library construction, biopanning, ELISA screening, sequencing, and recombinant expression, selected nanobodies were purified and characterized, leading to the preliminary exploration of a nanobody‐based sandwich ELISA for specific ...

Long‐term hippocampal alterations and cognitive impairment in a murine model of surgical sepsis

FEBS Open Bio, EarlyView.
Using a mouse model of surgical sepsis, we tested long‐term memory and analyzed the transcriptome of single cells isolated from the hippocampus. Survivor mice showed worse memory, loss of certain brain cell subpopulations, and abnormal immune cell activity—suggesting that post‐sepsis brain alterations may be linked to cognitive deficits.

Cyclic azapeptide CD36 ligand attenuates cardiac injury and reduces long‐chain fatty acid accumulation after myocardial ischemia–reperfusion in mice

FEBS Open Bio, EarlyView.
In a murine model of myocardial ischemia and reperfusion (MI/R), the CD36 azapeptide ligand MPE‐298 reduces cardiac injury and transiently lowers left ventricular long‐chain fatty acids (LCFAs) accumulation 3 h after reperfusion, accompanied by a decrease of oxidative stress and inflammation‐associated genes' expression in the heart and adipose tissue.
