0079496KatiyarThis grant supports the acquisition of a UV microRaman spectrometer at the University of Puerto Rico, San Juan. The instrument provides means for both fundamental and applied studies in materials where the conventional Raman signal is too weak. Then, it becomes necessary to use specialized techniques such as near resonance excitation and the possibility of interference enhancement, available in the current instrument along with higher scattering efficiency, higher sensitivity, selectivity and spatial resolution. The technique will be used to study ferroelectrics, solid state ionics and other wide bandgap materials. Such a non-destructive technique is also useful for the studies of biological systems. Thus there will be a direct impact on the studies of biological molecules at the Medical Campus of UPR. There will be further strengthening of research collaboration with Government laboratories and other universities facilitated by the exchange of data in the range of submicron to nanometer lengthscales in various materials.This grant supports the acquisition by the University of Puerto Rico, a specialized instrument, ultra-violet Raman spectrometer, used to study materials over varying resolutions and with tremendous sensitivity. The materials will be examined using ultraviolet lasers and will be studied for a broad range of their properties. The technique can and will also be used to study biological materials.

0079496 KatiyarThis grant supports the acquisition of a UV microRaman spectrometer at the University of波多黎各，圣胡安. 该仪器为传统拉曼信号太弱的材料的基础和应用研究提供了手段。 然后，有必要使用专门的技术，例如近共振激发和干扰增强的可能性，这些技术在当前仪器中可用，沿着具有更高的散射效率、更高的灵敏度、选择性和空间分辨率。 该技术将用于研究铁电体、固态离子学和其他宽带隙材料。 这种非破坏性的技术对于生物系统的研究也是有用的。 因此，将对UPR医学院的生物分子研究产生直接影响。 将进一步加强与政府实验室和其他大学的研究合作，通过交流各种材料的亚微米至纳米尺度的数据，这项赠款支持波多黎各大学购置一台专门仪器，即紫外线拉曼光谱仪，用于研究各种分辨率和极高灵敏度的材料。 这些材料将使用紫外激光进行检查，并将研究其广泛的特性。 该技术也可以并将用于研究生物材料。
