Julia Fulghum and Javed Khan of Kent State University are supported by the Division of Chemistry under the Information Technology Research (ITR) program to create new methods for the non-destructive, three-dimensional characterization of heterogeneous, solid polymeric materials. Data will be acquired from polymer samples of increasing complexity using a variety of analytical techniques, including x-ray photoelectron spectroscopy, time-of-flight secondary ion mass spectrometry, and Fourier transform infrared spectroscopy. All of these methods can be used to obtain chemical information from different sample volumes, and to generate multidimensional data sets. Multivariate statistical analysis and classification methods will be used to enhance interpretation of the acquired data sets, ultimately enabling creation of a unified polymer framework, called an active knowledge mesh. The combined system will create synergy between the computer and the user in large and complex information space exploration, posing interesting challenges for multi-modal data analysis and its multi-perspective visualization.Polymers are widely used in a variety of high technology applications. For example, many current and proposed biomaterials are polymers, and polymers are contained as well in composites used for a light aircraft and automobiles. Commercially important materials often involve molecularly complex polymer blends whose surface chemistry and structure are particularly challenging to analyze. Outcomes from this project are expected to improve the understanding and evaluation of complex polymer blend characteristics, and ultimately enable enhanced control of technologically important materials properties.

肯特州立大学的Julia Fulghum和Javed Khan得到了信息技术研究（ITR）计划的化学部门的支持，以创建新方法，以实现异质，固体聚合材料的非破坏性，三维表征。 使用各种分析技术，包括X射线光电学光谱，飞行时间二级离子质谱法和傅立叶变换红外光谱，将从增加复杂性的聚合物样品中获取数据。 所有这些方法可用于从不同的样品体积中获取化学信息，并生成多维数据集。 多元统计分析和分类方法将用于增强对获得的数据集的解释，最终使创建统一的聚合物框架（称为活动知识网格）。 合并后的系统将在大型和复杂的信息空间探索中产生计算机与用户之间的协同作用，对多模式数据分析及其多镜头可视化提出了有趣的挑战。项目广泛用于各种高科技应用中。 例如，许多当前和拟议的生物材料是聚合物，并且聚合物也包含在用于轻型飞机和汽车的复合材料中。 商业上重要的材料通常涉及分子复杂的聚合物混合物，其表面化学和结构在分析方面特别具有挑战性。 预计该项目的结果将提高对复杂聚合物混合特性的理解和评估，并最终能够增强对技术重要材料特性的控制。
