Improved Nishihara model considering the effect of moisture content on the whole shear creep process of shale

, 2022
Abstract The moisture content is closely related to the shear creep deformation behavior of soft rock, and the linear creep deformation behavior of soft rock can be described by the classical Nishihara model. However, the classical Nishihara model cannot describe the deformation characteristics of the whole process of shear creep including ...

Experimental investigation of the creep damage evolution of coal rock around gas extraction boreholes at different water contents.

PLoS ONE, 2023
The creep process of the coal rock around the extraction boreholes under stress-water coupling is an important factor affecting the stability of the boreholes. To study the influence of the water content of perimeter of the coal rock around the boreholes

Mechanism of the Photodecomposition of Stable Triarylmethyl Radicals

Angewandte Chemie, Volume 138, Issue 11, 9 March 2026.
Photolysis of luminescent chlorinated trityl radicals was studied with density functional theory and the decomposition products were isolated and characterized. It proceeds by a 5‐electron electrocyclization then a 1,8‐sigmatropic chloride shift, forming non‐emissive, less stable fluorenyl radicals.

Magnetic Field Amplification Associated with the Richtmyer-Meshkov Instability

, 2012
The amplification of a magnetic field due to the Richtmyer-Meshkov instability (RMI) is investigated by two-dimensional MHD simulations. Single-mode analysis is adopted to reveal definite relation between the nonlinear evolution of RMI and the field ...
