The Maier-Saupe theory is employed in order to calculate order parameters (P 2 ) , (P4) f rom the nematic potential q. The relation between <r=q/(RT) and S = (P2) corresponds well with a recently established formula by Kalmykov. The relation between the order parameters is in accordance with the analytic expression (P4)=5/l (P2) proposed by Zanonni, but deviates significantly f rom the Faber mo...
Typical morphology substrates can improve the efficiency of surface-enhanced Raman scattering; the need for SERS substrates of controlled morphology requires an extensive study. In this paper, one-dimensional ZnS:Al nanostructures with the width of approximately 300 nm and the length of tens um, and micro-scale structures with the width of several um and the length of tens um were synthesized v...
Emphasizing the contribution of Professor Roger A Cowley, FRS to the Theory of Raman Scattering from crystals, the development of the Theory of Raman Scattering since 1928 has been briefly discussed. Some experimental studies of Strontium Titanate using Inelastic Neutron Scattering, Raman Scattering, Electro-paramagnetic resonance measurement and X-ray & Gamma Ray techniques has been briefly di...
A scanning water Raman-lidar has been designed and constructed to study surface-atmosphere processes with high spatial and temporal resolution. Analytical methods are also being developed to analyze the information this lidar can take. The lidar is able to measure the absolute water content and then calculate evaporative fluxes and other atmospheric parameters quickly over relatively large area...
