Abstract

Easy come, easy go? Transport resistances on particle surfaces are important for mass transfer in nanoporous materials and bulk diffusion in crystals. Interference microscopy and IR micro-imaging are shown to be excellent tools for determining such transport resistances. By studying short-chain-length alkane guest molecules in crystals of the metal-organic framework compound Zn(tbip) a data collection of surface permeabilities is established.

摘要

来得容易，去得也快？颗粒表面的传输阻力对于纳米多孔材料中的传质和晶体中的体扩散很重要。干涉显微镜和红外显微成像被证明是确定此类传输阻力的优秀工具。通过研究金属有机骨架化合物Zn(tbip)晶体中的短链烷烃客体分子，建立了表面渗透率的数据集。
