Mar 10 2011 · Thermal boundary resistance (TBR) at a liquid-solid interface that consists of simple Lennard-Jones atoms is studied by molecular dynamics simulation. A liquid layer is confined narrowly between flat solid surfaces in the simulation and the mean density of the confined liquid is varied. A thermal gradient is imposed in the system by applying constant heat flux and TBR is calculated using

Effect of liquid media on the ultimate strength
Experiments conducted in low-molecular alcohols at 10°C show that the ultimate strength durability (time-to-fracture) and development of irrecoverable deformation of viscous flow depend very strongly on the nature of the liquid medium whereas the development of the elastic component of deformation is independent of the nature of the alcohols.
