Structure/property relationships of active sites in crystals, amorphous materials and liquids

在生物学，医学和工业中具有重要意义的材料的磁性将通过以下方式进行研究： 电子磁共振技术（也称为EMR/EPR/ESR），使用顺磁中心作为这些材料中活性位点的探针。[This该技术基于与医院中使用的MRI（磁共振成像）技术相同的原理。待研究的样品是（i）单晶，可用作磷光体，并可替代二氧化硅栅极晶体管;（ii）纳米结构状态的非晶材料：用于开发自旋电子器件的稀磁半导体（DMS），其中可以操纵电荷和自旋配置。掺杂钴和铁离子的氧化物半导体DMS是最有前途的主体系统之一。 脉冲EMR技术[双量子相干（DQC），双电子-电子共振（DEER）和电子-电子双共振（ELDOR）]将在计算上被利用，以发展测量生物系统中距离的理论，例如膜，这是一项前沿研究，不可能用X射线技术。 目标是：（1）开发适合作为激光器、磷光体的材料和用作二氧化硅栅极氧化物的替代物的材料。(2)将DMS样品开发为自旋电子器件。(3)涉及2D-ELDOR和DQC/DEER技术的双标记蛋白质项目将导致生物系统中的距离测量，例如膜，这一主题为人类基因组项目中的生命蓝图提供了线索。 另一个拟研究的相关项目是用作MRI和EPRI（EPR成像）造影剂、磁性标尺和量子肘的多氮氧化物的磁性表征，从而导致量子计算。

Magnetic properties of materials of significant interest in biology, medicine, and industry will be studied by electron magnetic resonance techniques (also referrred to as EMR/EPR/ESR) , using paramagnetic centres as probes at active sites in these materials. [This technique is based on the same principle as that of MRI (Magetic Resonance Imaging) technique used in the hospitals.] The samples to be investigated are (i) single crystals, useful as phosphors, and replacement for silicon dioxide gate dielectrics;(ii) amorphous materials in nano-structure state: Dilute magnetic semiconductors (DMS) to be used to develop spintronic devices where the charge and spin configuration can be manipulated. The oxide semiconductor DMS doped by cobalt and iron ions are among the most promising host systems. Pulsed EMR techniques [double quantum coherence (DQC), double electron-electron resonance (DEER), and electron-electron double resonance (ELDOR)] will be exploited computationally to develop the theory to measure distances in biological systems, e.g. membranes, a cutting-edge research, not possible with the X-ray technique. The objectives will be: (1) to develop materials suitable as lasers, phosphors, and materials to be used as replacement for silicon dioxide gate dielectrics. (2) to develop DMS samples as spintronic devices. (3) The bilabelled proteins project involving 2D-ELDOR and DQC/DEER techniques would lead to distance measurements in biological systems, such as membranes, a topic providing clues into blueprints of life in the human genome project. Another related project proposed to be investigated is magnetic characterization of poly-nitroxides for use as MRI and EPRI (EPR Imaging) contrast agents, magnetic rulers and quantum cubits, leading to quantum computing.
