The ability to entrap drugs within vehicles and subsequently release them has led to new treatments for a number of diseases. Based on an associative phase separation and interfacial diffusion approach, we developed a way to prepare DNA gel particles without adding any kind of cross-linker or organic solvent. Among the various agents studied, cationic surfactants offered particularly efficient ...

Room-temperature ionic liquids exert vanishingly small vapor pressures under ambient conditions. Under reduced pressure, certain ionic liquids have demonstrated volatility, and they are thought to vaporize as intact cation-anion ion pairs. However, ion pair vapors are difficult to detect because their concentration is extremely low under these conditions. In this Letter, we report the products ...

Pair plasmas consisting of only positiveand negative-charge particles of equal mass have attracted special attention because they maintain space-time symmetry. A fullerene pair-ion plasma, consisting of positive and negative ions of equal mass (C60 and C60), has been generated and its collective phenomena have been investigated experimentally [1]. In order to investigate more extensive physical...
