9802775RajeshwarThis Americas Program award will fund a three-year cooperative research project between Drs Krishnan Rajeshwar and Norma de Tacconi, University of Texas, Arlington (UTA), and Dr. R. O. Lenza, and a group of researchers from the Instituto de Investigaciones Fisicoquimicas Teoricas y Aplicadas (INIFTA), Universidad Nacional de La Plata, Argentina, to develop and characterize new families of electrochromic (EC) and photoelectrochromic (PEC) thin films. These are thin films that change their optical absorbance or reflectance in response to an electrical or electrochemical impulse. Particular attention will be paid to the optimization of experimental variables to bring about good reversibility, fast time response and long-term stability to these new generation devices. The mechanistics aspects associated with the color changes will be monitored in situ by electronic and vibrational spectroscopies as well as by conventional electrochemical and photoelectrochemical techniques. The coatings have many potential applications including smart windows, displays, and mirrors.The research profits from the complementary expertise of the collaborators, as well as by the facilities at both institutions. The electrochemical-photoelectrochemical quartz crystal microgavimetry methods will be done at UTA, while the spectroscopic methods will take place at INIFTA.***

9802775 Rajeshwar这个美洲项目奖将资助一个为期三年的合作研究项目，该项目由德克萨斯大学阿灵顿分校的Krishnan Rajeshwar博士和Norma de Tacconi博士以及R. O. Lenza和来自阿根廷拉普拉塔国立大学的Instituto de Investigaciones Fisicoquimicas Teoricas y Aplicadas（INIFTA）的一组研究人员开发和表征了新的电致变色（EC）和光电致变色（PEC）薄膜家族。这些是响应于电或电化学脉冲而改变其光学吸收或反射的薄膜。将特别注意实验变量的优化，使这些新一代器件具有良好的可逆性，快速的时间响应和长期稳定性。 与颜色变化相关的机械学方面将通过电子和振动光谱以及传统的电化学和光电化学技术进行原位监测。 该涂层具有许多潜在的应用，包括智能窗户，显示器和镜子。该研究受益于合作者的互补专业知识，以及两个机构的设施。 电化学-光电化学石英晶体微重力法将在UTA进行，而光谱法将在INIFTA进行。
