ÐAn overview on methodology and leading-edge applications of atomistic computational materials science based on quantum mechanical concepts is presented.

in this study, the nonlinear optical properties and optical limiting performance of the silver nanoparticles (agnps) in distilled water are investigated. the nonlinear absorption coefficient of the colloid is measured by the z-scan technique. the optical limiting behavior of the agnp suspension is investigated under exposure to nanosecond laser pulses at 532 nm. the results show that nonlinear ...

THE Wechsler Intelligence Scale for Children has grown logically out of the Wechsler-Bellevue Intelligence Scales used with adolescents and adults [4]. In fact, most of the items in the WISC are from Form II of the earlier scales, the main additions being new items at the easier end of each test to permit examination of children as young as five years of age. Even though the materials overlap, ...

On a microscopic scale, a pyrotechnic material is made of a polymer matrix containing grains with different sizes and shapes. Its physical behaviour can be predicted by homogenization. Information about the morphology of the grains can be obtained by different ways. One of these ways is 3D image processing. This has been made easier by the use of a new imaging technique, the microtomography, al...
