Recently, microfluidic system has been utilized for the supercritical extraction because of controllable mass and heat transfer. The flow patterns in the microfluidic system for supercritical CO2 + solvent mixture are also studied at various operation factors, such as temperature, pressure, flow rate and solvent species. This article gives the extraction of phenolic acids into supercritical CO2 from the aqueous solution using microfluid system. The effect of the flow patterns in the microfluid system on the extraction efficiency is also discussed.

Deep-sea organisms have estab-lished intracellular mechanisms to cope with such extreme environments. A living cell is composed of myriad molecules including nucleic acids, proteins, lipids, ions, and various low molecular compounds. These molecules interact with each other transiently or statically, eventually eliciting innumerable intermolecular interactions even in a small microbial cell. The complexity hampers the understandings of adaptive mechanisms to high pressure employed by deep-sea organisms. Studies with model organisms such as a bacterium Escherichia coli and a yeast Saccharomyces cerevisiae offer breakthroughs to unravel the effects of high pressure on the complex intermolecular networks in living cells.

In considering weak interaction systems such as biological and supramolecular reactions on the basis of thermodynamics, enthalpy and entropy changes exquisitely keep the balance each other according to the enthalpy-entropy compensation law, meaning that it seems to be difficult to control reactions/rates by only either of these parameters. On the other hand, reaction/activation volume change (DV)-based hydorstatic pressure (P) control turns out to be an alternative to the conventional control method. In this review, we wish to report our recent hydrostatic pressure-spectroscopic results on DV as solvation, conformational change, molecular recognition, and biological reaction.
