"This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)."Professor David Statman of Allegheny College is supported by the Analytical and Surface Chemistry Program in the Division of Chemistry to study the interactions between azo dyes, nematic liquid crystals, and polymer surfaces that lead to surface director gliding, and affect bulk reorientation. Photoinduced reorientation and surface gliding will be measured using various pump-probe techniques. The goal is to enhance our understanding of how photoexcitation of the dye facilitates reorientation of the easy axis at polymer surfaces. It is anticipated that this research may lead to new technologies based on liquid crystal materials. The educational activities include training of undergraduate students at Allegheny College, and exposing them to an international research experience at the Research Institute for Solid State Physics and Optics of the Hungarian Academy of Sciences.

“该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。“阿勒格尼学院的大卫·斯塔曼教授得到化学系分析和表面化学项目的支持，研究偶氮染料、液晶和聚合物表面之间的相互作用，这些相互作用导致表面指向矢滑动，并影响本体重取向。光致重定向和表面滑动将使用各种泵浦探测技术进行测量。 我们的目标是提高我们的理解，如何光激发的染料有利于在聚合物表面的易轴重定向。预计这项研究可能会导致基于液晶材料的新技术。教育活动包括在阿勒格尼学院培训本科生，并使他们在匈牙利科学院固态物理和光学研究所获得国际研究经验。
