Strain-induced formation of carbon and boron clusters in boron carbide during dynamic indentation

Shear induced formation of carbon and boron nitride nano-scrolls.

A 'top down' synthesis of carbon and hexagonal boron nitride (h-BN) nano-scrolls has been developed using the shear forces within dynamic thin films of N-methyl-2-pyrrolidone (NMP) generated on a rapidly rotating spinning disc processor (SDP), along with a theoretical understanding of the formation of the scrolls.

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Mesoscale Modeling of Dynamic Compression of Boron Carbide Polycrystals

An anisotropic nonlinear elastic model is advanced for crystals belonging to either of two polytypes of boron carbide ceramic. Crystals undergo transformation to an isotropic, amorphous phase upon attainment of a local state-based criterion associated with a loss of intrinsic stability. The model is implemented using the dynamic finite element method, and is demonstrated on a representative vol...
