Simulating Confined Fluids in Nanoporous Materials
If people could shrink themselves down and enter the world of nanoporous materials—solid materials like activated carbon or porous glasses that have pores of nanometer size—they would encounter exotic phenomena that were quite unexpected on the basis of everyday experience. Even thermodynamic properties thought of as constant such as the freezing point of water can be markedly depressed when fl...
متن کاملNMR Studies on the Properties of Polymers in Supercritical CO2
Using NMR spectroscopy and NMR imaging, the behaviour of polymers in supercritical CO2 (sc-CO2) using a custom-made cell designed from poly(ether ether ketone) (PEEK) has been observed. The mechanism of swelling of polymers in sc-CO2 and the overall effects of sc-CO2 on the transport properties of both small and large molecules has been studied. We report on the swelling characteristics of radi...
متن کاملElectrochemistry in supercritical fluids
A wide range of supercritical fluids (SCFs) have been studied as solvents for electrochemistry with carbon dioxide and hydrofluorocarbons (HFCs) being the most extensively studied. Recent advances have shown that it is possible to get well-resolved voltammetry in SCFs by suitable choice of the conditions and the electrolyte. In this review, we discuss the voltammetry obtained in these systems, ...
متن کاملNanoporous materials.
The current review article attempts to cover the field of nanoporous materials, thereby materials with voids of the order of 1 nm to 100 nm or even larger. Concepts, that have an effect on a more general basis, are introduced and the common features among the different classes of nanoporous materials are demonstrated enabling understanding their formation and stability. It is seen that the most...
متن کاملElectrodeposition from supercritical fluids.
Recent studies have shown that it is possible to electrodeposit a range of materials, such as Cu, Ag and Ge, from various supercritical fluids, including hydrofluorocarbons and mixtures of CO2 with suitable co-solvents. In this perspective we discuss the relatively new field of electrodeposition from supercritical fluids. The perspective focuses on some of the underlying physical chemistry and ...
