Scattering activity

A frequency job begins by computing the energy of the input structure. It then goes on to compute the frequencies at that structure. Gaussian predicts the frequencies, intensities, and Raman depolarization ratios and scattering activities for each spectral line ...

In order to link these scattered activities and to create an international network of historians of chemistry, some time ago the European Science Foundation in Strasbourg initiated a five year research program on The Evolution of Chemistry, 1789-1939 , which has yielded a series of conferences and a fair number of books. When this program came to an end in 1997, it was felt that this network should be used - in a sort of follow-up project - to focus interest in, and to stimulate research on, the history of twentieth-century chemistry.

Colony scattering is probably the easiest assay for detecting factors able to induce cell movement. It was originally described by Stoker and Perryman (1985), to detect a scattering activity for MDCK cells present in fibroblast conditioned medium. 

Silver films are formed on meso- and macroporous silicon (mejo-PS and macro-PS) by the immersion plating. Scanning electron microscopy reveals the formation of Ag islands along the dendritic structure at the surface of mejo-PS and Ag nanoparticles over the pore walls in the case of macro-PS. The surface-enhanced Raman scattering activity of Ag-macro-PS substrates appears to be greater in comparison with that for Ag-mcio-PS. 

The classic Ziegler-Natta heterogeneous catalysts initiate polymerization at diverse, somewhat randomly scattered active sites on modified TiCls crystals, with the result that polymer chain length is variable even though essentially complete isotacticity can be achieved. Furthermore, these catalysts offer little opportunity to manipulate the degree of stereoregularity and hence the mechanical properties of the product—the Ziegler-Natta polypropylenes are exclusively isotactic. 

Recently, the production of nanofibres using nanocomposites has attracted attention. This is due to the fact that this type of nanofibre combines the unique properties of nanocomposites with the outstanding characteristics of nanofibres. Metal/polymer nanocomposites have not only the potential to meet the requirements of applications such as photonic and electric sensors, filters, and artificial tissue, but also can act as catalysts. Silver nanoparticles are the most common embedded metal nanoparticles used in conjunction with polymers. This is because silver nanoparticles exhibit remarkable properties including catalytic activity, surface-enhanced Raman scattering activity, high electrical conductivity and antimicrobial activity. 

Serrano et have used similar methods to calculate the dipole moment, polarizability and first hyperpolarizability of CaC and have used the results to predict the Rayleigh and Raman scattering activity.
