MRI: Acquisition of an Automatic High Pressure Physisorption Analyzer for the Creation of a Physical Adsorption Laboratory

凭借化学专业研究仪器计划的这一奖项，来自Universidad Del Turabo的Rolando Roque-Malherbe教授及其同事Agustin Rios，Anastacio Emiliano和塞萨尔Lozano将获得自动高压物理吸附分析仪。该提案旨在加强各级的研究和教育，特别是在以下领域：（a）甲烷储存的金属有机框架;（B）从气流中分离小分子的普鲁士蓝类似物;和（c）用于二氧化碳储存的孔径增大的硝普钠高压物理吸附分析仪利用分子之间非常弱的吸引相互作用，这是由所谓的货车范德华相互作用引起的。通常，高压被施加到与固体基底接触的气体。随着压力的增加，气体分子在不同程度上被基板吸引。在适当的条件下，这些弱相互作用允许气体分离。如果另外操纵基底的孔，则相互作用可以增加，并且这样的固体可以用于储存气体。有用的例子是二氧化碳，它可能会导致全球变暖，并可能在浓缩条件下作为化学反应的原料。

With this award from the Chemistry Major Research Instrumentation Program, Professor Rolando Roque-Malherbe from Universidad Del Turabo and colleagues Agustin Rios, Anastacio Emiliano and Cesar Lozano will acquire an automatic high pressure physisorption analyzer. The proposal is aimed at enhancing research and education at all levels, especially in areas such as (a) metal organic frameworks for methane storage; (b) Prussian blue analogues for small molecules separation from gas flows; and (c) pore size augmented nitroprussides for carbon dioxide storage.A high pressure physisorption analyzer takes advantage of the very weak attractive interactions between molecules, which arise from so-called van der Waals interactions. In general, high pressure is applied to a gas in contact with a solid substrate. As the pressure increases, the gas molecules are attracted to various degrees by the substrate. Under appropriate conditions, these weak interactions allow separation of gases. If additionally the pores of the substrate are manipulated, the interactions may increase and such solids may be used to store gases. Useful examples are those of carbon dioxide, which may contribute to global warming and may serve as feedstock for chemical reactions under concentrated conditions.
