Anisotropic constitutive relationships in energetic materials: PETN and HMX [PDF]

open access: yes, 2007
This paper presents results of first-principles density functional calculations of the equation of state (EOS) of PETN-I and beta-HMX. The isotropic EOS for hydrostatic compression has been extended to include uniaxial compressions in the [100], [010 ...

Extraction and identification of spectrum characteristics of coal and rock hydraulic fracturing and uniaxial compression signals

open access: yesInternational Journal of Coal Science & Technology, 2023
Microseismic (MS) events generated during coal and rock hydraulic fracturing (HF) include wet events caused by fracturing fluid injection, in addition to dry events caused by stress perturbations.

A Smart Bio‐Battery Facilitates Diabetic Bone Defect Repair Via Inducing Macrophage Reprogramming and Synergistically Modulating Bone Remodeling Coupling

open access: yesAdvanced Functional Materials, EarlyView.
This research presents a novel implantable bio‐battery, GF‐OsG, tailored for diabetic bone repair. GF‐OsG generates microcurrents in high‐glucose conditions to enhance vascularization, shift macrophages to the M2 phenotype, and regulate immune responses.

Crack‐Growing Interlayer Design for Deep Crack Propagation and Ultrahigh Sensitivity Strain Sensing

open access: yesAdvanced Functional Materials, EarlyView.
A crack‐growing semi‐cured polyimide interlayer enabling deep cracks for ultrahigh sensitivity in low‐strain regimes is presented. The sensor achieves a gauge factor of 100 000 at 2% strain and detects subtle deformations such as nasal breathing, highlighting potential for minimally obstructive biomedical and micromechanical sensing applications ...

Atomistic simulation of the uniaxial compression of black phosphorene nanotubes

open access: yesVietnam Journal of Mechanics, 2018
We study through molecular dynamics finite element method with Stillinger-Weber potential the uniaxial compression of (0, 24) armchair and (31, 0) zigzag black phosphorene nanotubes with approximately equal diameters.

Hydrostatic compression on polypropylene foam [PDF]

open access: yes, 2014
Models currently used to simulate the impact behaviour of polymeric foam at high strain rates use data from mechanical tests. Uniaxial compression is the most common mechanical test used, but the results from this test alone are insufficient to ...

Grain Boundary Space Charge Engineering of Solid Oxide Electrolytes: Model Thin Film Study

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates unprecedented control of grain boundary electrical properties in solid electrolytes. Selective diffusion of cations through grain boundaries in thin films enables 12 orders of magnitude variation in ionic resistance, proving that systematic chemical modification of grain boundary electrical properties is feasible.

Optical birefringence in uniaxially compressed aerogels

open access: yesNew Journal of Physics, 2010
The uniaxial strain dependence of refractive index anisotropy has been measured for a series of high-porosity aerogel samples. Uniaxial compression of compliant aerogels introduces an optical activity into the material. We report on the compression-dependent optical birefringence of samples with porosities from 95 to 99% under a uniaxial compression of
