The optical characteristics of reduced glutathione molecules between 0.2.THz and 2.4 THz have been investigated by THz time-domain spectroscopy (THz-TDS). The absorption characteristics and optical parameters of the reduced glutathione purged with Nitrogen at room temperature were obtained experimentally. The measured results were fitted well with the theoretical results computed by using Density Functional Theory (DFT) in far-infrared range. Also the conformation of the reduced glutathione molecule was simulated by Gaussian 03. This work has demonstrated significantly that THz-TDS spectroscopy can further be used to study other biological molecules in biological and biomedical engineering.

When a highly charged ion with many inner shell holes is approaching to a metallic surface, the conducting -band electrons in the metal can resonantly transfer into the high orbits of the projectile at a large distance. In this way, the ion could be temporarily neutralized to form a hollow atom with outer shell occupied and inner shells empty. The hollow atoms may de-excite by auto ionization, Auger electron emission and cascade radioactive X-rays. At the very moment when the projectile reaching the surface, its outer shell electrons will be partly peeled off, however the holes in the inner-most shell could still survive for a

We study target-searching processes on a percolation, on which a hunter tracks a target by smelling odorsit emits. The odor intensity is supposed to be inversely proportional to the distance it propagates. The Monte Carlosimulation is performed on a 2.dimensional bond-percolation above the threshold. Having no idea of the location of thetarget, the hunter determines its moves only by random attempts in each direction. For lager percolation connectivityP0.90, it reveals a scaling law for the searching time versus the distance to the position of the target. The scalingexponent is dependent on the sensitivity of the hunter. For smaller P, the scaling law is broken and the prohability offinding out the target significantly reduces. The hunter seems trapped in the cluster of the percolation and can hardlyreach the goal.
