Thermoresponsive polymer gels can be applied as culture beds for cell sheets, drug release agents for drug delivery, and sensing materials. In general, the shrinkage behaviors of thermoresponsive polymer gels...

The exoelectron emission phenomena from metals in peripheral-cutting and dry-friction processes were examined using a modified GM counter with a lathe-like device. Aluminum (Al), brass (Bs) and carbon steel (S45C) specimens were cut with a cemented carbide tool. The emission intensity (El) during the cutting process fluctuated considerably with the cutting time. The EE for the same cutting speed decreased in the order Al≫Bs≫S45C. In the friction process, a rotating metal bar (Bs and S45C) was pressed with a rectangular metal tool (Al, Bs and S45C) at various loads. The El varied very irregularly with the friction time and was almost the same magnitude for all the metal bar-metal tool couples, except for a S45C–Bs couple. The El increased along with an increase in the cutting and friction speeds, depth of a cut and the applied friction load.
