Experimental analysis of the height–diameter ratio effect of rock energy under uniaxial cyclic loading–unloading conditions
The deformation-to-failure process of rock is accompanied by the dissipation and release of energy and is the result of the mutual conversion of energy. The uniaxial compression and uniaxial cyclic loading–unl...

Effects of Confining Pressure and Temperature on the Energy Evolution of Rocks Under Triaxial Cyclic Loading and Unloading Conditions
The deformation and failure of rocks result from the dissipation and release of their internal energy. The energy evolution throughout the processes of deformation and failure in rock is a critical research to...

Experimental mechanical strength and deformation characteristics of deep damaged–fractured rock
Mechanical and structural properties of rocks after failure are different from those of intact rock. The stability of surrounding rock in deep underground engineering is closely related to the post-peak state....

Physical and micro-structural characteristics of limestone after high temperature exposure
Temperature is a major factor affecting physical and mechanical rock properties. With increasing temperature, a series of variations enlarge the internal defects within rocks, resulting in physical and mechani...

Interaction of antigen and antibody on core-shell polymeric microspheres
Monodispersed microspheres with polystyrene as the core and poly(acrylamide-co-N-acryloxysuccinimide) as the shell were synthesized by a two-step surfactant-free emulsion copolymerization. The core-shell morpholo...
