A lipophilic linear Fe(II) complex is dispersed as nanofibers in nematic liquid crystals and displays spin-crossover at temperatures higher than those observed for the bulk crystalline state; thermal bistability is also induced in the liquid crystal environment, reflecting increased ligand field splitting energy and enhanced cooperativity by liquid crystals.

For bulk liquid helium the bottom of the conduction band (V0) is above the vacuum level. In this case the surface of the liquid represents an electronic surface barrier for an electron to be injected into the liquid. Here we study the electronic conduction band for doped helium droplets of different sizes. Utilizing an electron monochromator, the onset of the (H2O)2- ion yield corresponding to ...

Acetic acid was separated from a dilute mixture using a commercial polyvinyl alcohol (PVA) membrane.  Intrinsic separation characteristics of the membrane were studied as a function of temperature.  The degree of membrane swelling decreased marginally with increase in feed temperature. At 25oC the maximum degree of swelling was found out to be 46.3%, which reduced to 39.5%...

When the high power ultrasound irradiates the liquid, small liquid droplets are generated from the liquid surface. This phenomenon is called as ultrasonic atomization [1]. Recently, it has been reported that ethanol is concentrated from the aqueous solution by ultrasonic atomization [2-4]. Since ultrasonic atomization scarcely accompanies the phase change, this is a great advantage comparing wi...

Membrane-targeting domains play crucial roles in the recruitment of signalling molecules to the plasma membrane. For most peripheral proteins, the protein-to-membrane interaction is transient. After proteins dissociate from the membrane they have been observed to rebind following brief excursions in the bulk solution. Such membrane hops can have broad implications for the efficiency of reaction...

We have investigated the adsorption and desorption of helium near its liquid-vapor critical point in silica aerogels with porosities between 95% and 98%. We used a capacitive measurement technique which allowed us to probe the helium density inside the aerogel directly, even though the samples were surrounded by bulk helium. The aerogel’s very low thermal conductivity resulted in long equilibra...

Quantitative polarity scales have been of great value in advancing our understanding of chemical and physical processes in bulk solvents. However, an understanding of the polarity at liquid interfaces has been more elusive and no scale of interface polarity currently exists. Following our demonstration that second harmonic spectroscopy can be used to measure interface polarity, we have determin...
