US-India Cooperative Research: Phase Selection in Ceramic Oxides under Non-Equilibrium Conditions, Award in Indian Currency

描述：该提案是由圣巴巴拉加利福尼亚大学的材料科学家Carlos Levi和班加罗尔印度科学研究所的Vikram Jayaram进行的美印研究合作。该项目名为“非平衡条件下陶瓷氧化物的相选择”。研究人员将研究在热力学平衡受到高度限制的条件下合成的陶瓷氧化物中氧化物微观结构的演变。该计划将侧重于相对简单的二元和更高组分系统，使用已被证明有潜力带来实质性亚稳态的技术。以这种方式产生的组合物将被热处理，以研究由非平衡结构向更稳定结构演变的状态层次。主要目的是加强对相选择过程的理解，它们与亚稳态基本形式的关系，以及它们通过随后的转变对微观结构演变的影响。范围：pi在这个领域有丰富的经验，并且在过去有过富有成效的合作。大部分实验工作将在印度科学研究所进行。美国合作者将在实验设计和结果分析方面提供指导，以及访问加州大学圣巴巴拉分校的雾化和表征设施。该研究有望与加州大学NSF材料研究实验室正在进行的结构陶瓷和功能无机氧化物合成研究产生互利的相互作用。该项目将为一名美国研究生提供一个独特的国际机会，参与班加罗尔印度科学院的实验研究。

Description: This proposal is for a US-Indo research collaboration between materials scientists Carlos Levi of the University of California, Santa Barbara and Vikram Jayaram of the Indian Institute of Science, Bangalore. The project is entitled `Phase Selection in Ceramic Oxides Under Non-Equilibrium Conditions.` The investigators will study the evolution of oxide microstructures in ceramic oxides synthesized under conditions wherein thermodynamic equilibrium is highly constrained. The program will focus on relatively simple binary and higher component systems using techniques with proven potential to bring about substantial metastability. Compositions produced in this manner will be heat treated to study the hierarchy of states by which the non-equilibrium structure evolves towards a more stable one. The primary objective is to enhance the understanding of phase selection processes, their relationship to fundamental forms of metastability, as well as their impact on microstructure evolution through subsequent transformations. Scope: The PIs have extensive experience in this area and have collaborated productively in the past. The bulk of the experimental work will be carried out at the Indian Institute of Science. The US collaborator will provide guidance in the design of experiments and analysis of results, as well as access to atomization and characterization facilities at the UC, Santa Barbara. The research is expected to generate a mutually beneficial interaction with the ongoing research on the synthesis of structural ceramics and functional inorganic oxides at the NSF Materials Research Laboratory at UC. This project will provide a unique international opportunity for a US graduate student to participate in the experimental research at the IISc, Bangalore.
