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

获得化学专业研究仪器项目的这一奖项后，图拉博大学的Rolando Roque-Malherbe教授及其同事Agustin Rios、Anastacio Emily iano和Cesar Lozano将获得一台自动高压物理吸附分析仪。该提议旨在加强所有层面的研究和教育，特别是在以下领域：(A)用于储存甲烷的金属有机骨架；(B)用于从气流中分离小分子的普鲁士蓝类似物；以及(C)用于储存二氧化碳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人的相互作用，这种相互作用源于所谓的范德华相互作用。一般情况下，高压作用于与固体衬底接触的气体。随着压力的增加，气体分子会不同程度地被衬底吸引。在适当的条件下，这些弱相互作用可以使气体分离。如果另外操纵衬底的孔，则相互作用可能增加，并且这种固体可用于存储气体。有用的例子是二氧化碳，它可能导致全球变暖，并可能在集中条件下用作化学反应的原料。

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.
