Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions
Advanced Functional Materials, EarlyView.This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

Damping ratio evolution of saturated Ningbo clays under cyclic confining pressure
Soil Dynamics and Earthquake Engineering, 2021Abstract The mechanical behaviours of soft clays under cyclic loading are not only related to loading parameters, but also the physical indices of soft clay. One-way cyclic triaxial tests with constant confining pressure were adopted, however, the stress field induced by traffic loads includes cyclic confining pressure and cyclic deviator stress.

Effects of cyclic confining pressure on the deformation characteristics of natural soft clay
Soil Dynamics and Earthquake Engineering, 2015Abstract To investigate the coupling effects of cyclic deviator stress and cyclic confining pressure on the deformation behavior of natural soft clay under partially-drained conditions, a series of one-way cyclic triaxial tests with and without cyclic confining pressure were carried out.

Abstract The post-cyclic mechanical behaviors of subgrade soil are usually assessed by conventional cyclic triaxial tests, however, the stress field induced by traffic loads consist of not only a cyclic deviator stress, but cyclic confining pressure and shear stress.

Measurement of Cartilage Fluid Pressurization in Confined Compression Cyclical Loading
Advances in Bioengineering, 1998Abstract In recent studies (Oloyede and Broom, 1991; Soltz and Ateshian, 1997, 1998) it has been demonstrated from experiment and theory that compressive stresses applied across the surface of articular cartilage are supported primarily by the hydrostatic pressurization of the interstitial fluid, under configurations of confined ...

Stress relaxation behaviour of marble under cyclic weak disturbance and confining pressures
Measurement, 2021Abstract Cyclic weak disturbance caused by blasting, drilling, earthquake and transport is an important factor to deep rock projects failure. In order to study the influence of cyclic weak disturbance on the stress relaxation of rock under different confining pressures, a step loading stress cyclic weak disturbance relaxation test was carried out on ...

The objective of this study was to experimentally verify the well-accepted but untested hypothesis that cartilage interstitial fluid pressurizes variously under the action of an applied cyclical stress in confined compression over a range of loading frequencies, contributing significantly to the cartilage dynamic stiffness.

Permanent deformation in terms of rutting is a major deterioration mode of bituminous bound pavements. The triaxial cyclic compression test (TCCT) is a scientifically accepted and standardised test method to assess the resistance to permanent deformation. Presently, the standard TCCT according to EN 12697-25 is carried out with cyclic axial loading and
