Electrospun fibrinogen-PLA nanofibres for vascular tissue engineering [PDF]

, 2016
Here we report on the development of a new type of hybrid fibrinogen–polylactic acid (FBG–PLA) nanofibres (NFs) with improved stiffness, combining the good mechanical properties of PLA with the excellent cell recognition properties of native FBG. We were

Dynamic nanoindentation by instrumented nanoindentation and force microscopy: a comparative review [PDF]

Beilstein Journal of Nanotechnology, 2013
Viscoelasticity is a complex yet important phenomenon that drives material response at different scales of time and space. Burgeoning interest in nanoscale dynamic material mechanics has driven, and been driven by two key techniques: instrumented nanoindentation and atomic force microscopy.

Production and characterization of the Cr35Fe35V16.5Mo6Ti7.5 high entropy alloy

Nuclear Materials and Energy, 2022
The microstructure, thermal stability, and mechanical properties of a novel Cr35Fe35V16.5Mo6Ti7.5 high-entropy alloy were studied. The mechanical properties were mapped by nanoindentation, and the results correlated with the microstructure and the ...

High temperature nanoindentation behavior of Al/SiC multilayers [PDF]

, 2012
Nanoscale Al/SiC composite laminates have unique properties, such as high strength, high toughness, and damage tolerance. In this article, the high-temperature nanoindentation response of Al/SiC nanolaminates is explored from room temperature up to ...

Dislocation Reaction Mechanism for Enhanced Strain Hardening in Crystal Nano-Indentations

Crystals, 2019
Stress−strain calculations are presented for nano-indentations made in: (1) an ammonium perchlorate (AP), NH4ClO4, {210} crystal surface; (2) an α-iron (111) crystal surface; (3) a simulated test on an α-iron (100) crystal surface.

Deep Learning Regressors of Surface Properties from Atomic Force Microscopy Nanoindentations

Applied Sciences
Atomic force microscopy (AFM) is a powerful technique to study the nanomechanical properties of a wide range of materials at the piconewton level. AFM force–indentation curves can be fitted with appropriate contact models, enabling the determination of ...
