0115000 Prasad描述:该奖项是为了支持纽约州立大学水牛城分校化学系兼光子学研究实验室主任Paras N.Prasad博士和埃及Shebin El-Kom梅诺菲亚大学物理系Raouf El-Mallawany博士之间的合作项目。这项研究的目标是开发和研究基于碲酸盐玻璃的新材料,以探索其在非线性应用中的潜力。研究内容包括:利用新的不同稀土和过渡金属氧化物制备高光学质量的碲酸盐玻璃(块状和光纤状),以获得高折射率、低色散的玻璃;光学测量,包括不同波长的折射率测量和红外透过率、热放大波长的测量;弹性表征测量,包括:玻璃转变、析晶温度、稳定性、纵向、剪切、体积、杨氏模数、泊松比和德拜温度,以及结构测定,如X射线衍射(XRD)、透射电子显微镜。范围:该项目支持两位具有这项研究专业知识和资源的知名科学家之间的合作。本课题对非晶态材料领域具有重要意义,在不断扩大的光子学领域具有广泛的应用前景。对碲酸盐玻璃的了解将对压力传感器和光学材料的发展产生影响。国际团队非常适合这个项目,因为这位埃及科学家在合成不同成分的碲酸盐玻璃方面拥有丰富的专业知识,而这位美国科学家在材料表征方面拥有丰富的专业知识。该项目通过开发可广泛应用的新材料,有可能极大地惠及双方。该项目将促进埃及和美国研究生的培训,他们将参与这一合作工作。该项目符合支持共同感兴趣领域的合作研究的INT目标。
英文摘要
0115000PrasadDescription: This award is to support a collaborative project between Dr. Paras N. Prasad, Department of Chemistry and Director of Photonics Research Laboratory, State University of New York at Buffalo, Buffalo, New York and Dr. Raouf El-Mallawany, Department of Physics, Menofia University, Shebin El-Kom, Egypt. The objectives of the research are to develop and study new material based on tellurite glasses for their potential for non-linear applications. The study will include: Preparation of high optical quality of tellurite glasses (in the bulk & fiber form) by using new different rare earth and transition metal oxides in order to get a glass with high refractive index and low dispersion, optical measurements which include the measurements of the refractive index at different wavelengths and the wavelength of IR transmission, thermal & Elastic characterization measurements which include: glass transformation, crystallization temperatures, stability, longitudinal, shear, bulk, Young's moduli, Poisson's ratio and Debye temperature of the produced glasses, and structural determinations like x-ray Diffraction (XRD), transmission electron microscope.Scope: The project supports collaboration between two well-recognized scientists who have the expertise and resources for this research. The topic is important to the field of amorphous materials, and has applications in the expanding arena of photonics. Understanding of tellurite glasses will have an impact in the development of pressure sensors and optical materials. The international team is quite suited for the project, as the Egyptian scientist has significant expertise in the synthesis of tellurite glasses of different compositions, and the US scientist has vast expertise in material characterization. This project has the potential to greatly benefit both sides by developing new materials that can have wide applications. The project will promote training of Egyptian and US graduate students who will participate in this collaborative work. This project meets the INT objective of supporting collaborative research in areas of mutual interest.
