The physical and chemical properties vapour pressure, boiling point and solubilities of all substances have their origin in the Coulomb interaction between the molecules. The various interactions itself derive from the drive to minimize the Coulomb energy of the valence electrons. A classification of the electrostatic interaction allows an exemplification and estimation of the interaction stren...

Morphological changes in Polyvinyl Butyral (PVB) electrospun nanofibres can be acquired by preparation of PVB spinning solution in different solvents.  Accordingly, three solvents, including ethyl alcohol, n-butanol and isopropanol, with diverse physical properties (e.g. boiling point, density, dipole moment and dielectric constant) were used to prepare PolyVinyl Butyral (PVB) spin...

A two-step acid/base-catalyzed silica gel has been aged in alcohol and water baths followed by various aprotic solvents with a wide range of surface tensions. Low temperature (CO 2) and high temperature (ethanol) aerogels were also prepared. The physical and chemical structures of gels dried from aprotic solvents were studied by a series of techniques (29Si MAS-NMR, nitrogen adsorption, SAXS, e...

We report that alkanethiol-capped Au nanoparticles can be linearly placed by toluene with its physical properties as well as its wettability in the presence of the nanoparticles. It is visually confirmed that toluene can be pinned with the aid of the nanoparticles to transport the nanoparticles to pinned contacts and to form linear placements. Whether the nanoparticles in various solvents can b...

Treatment of hydrogen sulfide (H2S) is important in many industrial processes including oil refineries, natural and biogas processing, coal gasification. The most mature technology for the selective capture H2S based on its absorption by chemical or physical solvents. However, only several compounds are currently used as (co)solvents industry, search new ones an task. experimental screening req...

Melamine-functionalized tri(p-phenyleneethynylene) self-assembles to form opaque and weak gels in aliphatic solvents which turned transparent and stable upon addition of a cyanurate, affording supramolecular nanostructures with distinct physical properties.
