Benjamin Widom of Cornell University is supported by an award from the Theoretical and Computational chemistry program for the theoretical study, by the methods of statistical mechanics and thermodynamics, of the energetics and structures of liquids and liquid mixtures, of the phase transitions such fluids undergo and of the structures and structural transformations of the interfaces between fluid phases. One study focuses on the borderline between two types of wetting transition, where a range of first-order wetting transitions and one of second-order transitions join at a point of "tri-critical" wetting; and to study the behavior of the line tension as that tricritical point is approached. Another study focuses on hydrophobic effects.The studies have broad impact in many important and very different areas of science, technology and society. For example, wetting is a central concern in soil science; it is crucial in industrial flotation and separation systems; it is also crucial for the proper action for the lungs in respiration. Hydrophobic effects have numerous manifestations throughout chemistry and biology.

康奈尔大学的Benjamin Widom获得了理论和计算化学计划的奖项，用于理论研究，通过统计力学和热力学的方法，液体和液体混合物的能量学和结构，这些流体经历的相变以及流体相之间界面的结构和结构转换。一项研究集中在两种类型的润湿过渡之间的边界线，其中一系列的一阶润湿过渡和一个二阶过渡在“三临界”润湿点处加入;并研究接近三临界点时的线张力的行为。另一项研究关注疏水效应，这些研究在科学、技术和社会的许多重要和非常不同的领域产生了广泛的影响。例如，润湿是土壤科学中的核心问题;它在工业浮选和分离系统中至关重要;它对肺在呼吸中的适当作用也至关重要。疏水效应在化学和生物学中有许多表现。
