发展了微通道层流多相流界面现象的准弹性激光散射光谱分析技术。测量了金属螯合物通过水/甲苯界面的传输现象，并测量了螯合物在传输初始步骤中的瞬时吸附。测量了水/甲醇互溶界面，首次确定了互溶界面的界面自由能。预计muQELS不仅对于传输和混合的物理化学研究非常有效，而且对于非均相反应的元素过程分析也非常有效。
Microscopic quasi-elastic laser scattering (muQELS) spectroscopy has been developed for analysis of interfacial phenomena at laminar multiphase microflow in a microchannel. Transport phenomena of a metal chelate through a water/toluene interface were measured, and transient adsorption of the chelate in the initial step of the transport was measured. A water/methanol miscible interface was also measured, and the interfacial free energy of a miscible interface was determined for the first time. The muQELS is expected to be very effective not only for physicochemical investigations of transport and mixing, but also for elemental process analysis of heterogeneous reactions.
