This award will support collaborative research between Dr. Ron Neuman, Auburn University, and two Swedish researchers: Professor Per Stenius, Institute for Surface Chemistry, and Professor Per Martin Claesson, Department of Physical Chemistry, The Royal Institute of Technology, Stockholm. The objective of the project is to investigate the feasibility of employing a surface force apparatus for studies of model papermaking systems. In particular, the forces between model cellulose surfaces will be directly measured to identify and quantify the fundamental interactions between cellulose surfaces and other surfaces of intrinsic interest and technological importance to pulping and papermaking. Technique development will include the preparation of model cellulose and lignin surfaces on molecularly smooth mica substrates by the method of Langmuir.Blodgett monolayer deposition. Preliminary monolayer experiments will be initiated prior to the visit to ensure productive surface force measur>ements. The facilities and experience in surface force measurements of the Institute Surface Chemistry in Stockholm complement the expertise of the principal investigator in surface and colloid chemistry of papermaking, monomolecular films, and Langmuir.Blodgett monolayer deposition. The results of this research are expected to have important applications in the pulp and paper industries.

该奖项将支持奥本大学的Ron Neuman博士和两名瑞典研究人员的合作研究：表面化学研究所的Per Stenius教授和斯德哥尔摩皇家理工学院物理化学系的Per Martin Claesson教授。该项目的目的是调查使用表面力装置研究模型造纸系统的可行性。特别是，将直接测量模型纤维素表面之间的力，以识别和量化纤维素表面与其他对制浆和造纸具有内在意义和技术重要性的表面之间的基本相互作用。技术开发将包括通过朗缪尔·布洛杰特单层沉积的方法在分子光滑的云母衬底上制备纤维素和木质素模型表面。在访问之前，将启动初步的单层实验，以确保有效的表面力测量和GT；斯德哥尔摩表面化学研究所在表面力测量方面的设施和经验补充了造纸、单分子薄膜和朗缪尔·布洛杰特单层沉积的表面和胶体化学首席研究员的专业知识。本研究成果有望在制浆造纸工业中具有重要的应用价值。
