4-(4'-Butoxyphenyl)phenyl-beta-O-D-glucoside was synthesized as a low-molecular-mass gelator. It was able to immobilize a variety of aqueous and organic solvents in large amounts through the formation of three-dimensional self-assembled fibrillar networks. The morphologies of the aggregates depended on the nature of solvent where they were formed. Planar ribbons were observed in water, while he...

This article analyses experiments on the kinetics of internal electrochromism thin (micron) films hydrated vanadium pentoxide xerogel with point contacts. It describes a cylindrical model electrochromic colouration, which was used to evaluate concentration colour centres in initial film and after additional hydrogenation this by plasmaimmersion ion implantation.When we compared calculated value...

A new silver(I) complex with 1-phenyl-3-(quinolin-5-yl)urea has been prepared, acting as a supramolecular supergelator in the presence of polar solvents. In open vials temperature dependent, reversible gel-to-xerogel transition is observed, while in sealed vials direct crystallization of four polymorphs of the same gelling compound is achieved, depending on the gelling solvent.

A method of fabricating sol-gel quantum dot (QD) films is demonstrated, and their optical, structural and electrical properties are evaluated. The CdSe(ZnS) xerogel films remain quantum confined, yet are highly conductive (10(-3) S cm(-1)). This approach provides a pathway for the exploitation of QD gels in optoelectronic applications.

A novel route has been developed to fabricate different carbon nanostructures having individual morphology of carbon nanoparticles: nanofullerene, nanocube, nanoleaf and porous nanorods, through the combustion of carbon xerogel with nitric acid. These fabricated nanostructures exhibited bright green fluorescence under the exposure of UV light.

The electromagnetic properties of Carbon-Graphene Xerogel (CGX), Flaky graphite (GR) and Nickel-Zinc ferrite (FeNiZn) composites in polystyrene (PS) matrix were studied the X-Band range (8.2 – 12.4 GHz). In this work Expanded Polystyrene (EPS) waste material was processed into through recycling EPS. obtained utilized as dielectric matrix, mainly because PS is a well-known organic polymer that p...

A eficiência fotocatalítica dos materiais avaliada pela decomposição azul metileno. Os foram produzidos dispersão em gel carbono, durante policondensa...

A number of researchers are attempting to develop a biosensor based on terahertz sensing. Key to the realization of any biosensor system is the access of the target molecules to the sensor. In the case of using terahertz spectroscopy, there are limitations due to high attenuation by water and sensitivity levels. In order to have a significant response at THz frequencies generally requires a min...
