A B S T R A C T Cellulose acetate (CA) was modified using Diallylamine (DAA). The structure of the modified polymer was characterized by 13 C-NMR. The chemical modification is based on the reaction between the active hydrogen of the amino group of Diallylamine molecule and acetyl group of the glucopyranose ring in cel…
Graphene/CdSe nanoparticle monolayer/graphene sandwich structures were fabricated to explore the interactions between these layered materials. Electrical transport across these heterostructures suggests that transport is limited by tunneling through the nanoparticle (NP) ligands but not the NP core itself. Photoconduc…
Research interest in ZnO nanostructure derives from their excellent luminescent properties and availability of low cost fabricating and processing, which hold promise for the development of electronic and optoelectronic devices. In this work, the synthesis routes for zinc oxide (ZnO) nanoparticles and nanorods, their…
Nanotubes with variable hydrophobic interiors were prepared by disassembling anionic micelles in the inner walls of positive charge bearing conjugated polymer nanotubes.
The possibility of enhancing the frequency performance of electrochemical capacitors by tailoring the nanostructure of the carbon electrode to increase electrolyte permeability is demonstrated. Highly porous, vertically oriented carbon electrodes which are in direct electrical contact with the metallic current collect…
The paper presents electrospinning technology used for the production of polymer nanofi brous mats. Surface properties of polymer nanofibrous mats electrospun from poly (vi nylidene fluoride) (PVDF) and poly (vinyl chloride) (PVC), and modified in dielectric bar rier discharge (DBD) are presented. The contact angle of…
Stimuli-responsiveness is an important characteristic of nanocarriers that can deliver therapeutic molecules in a controlled and on-demand manner.
We revealed the inherent instability of α''-Fe16N2 in hydrogenous atmospheres due to the denitrification toward α-Fe by forming NH3 at the particle surface. Coating the particle surface with SiO2 to suppress the formation of NH3 has proven to be a simple yet powerful method to enhance the stability of α''-Fe16N2 in hy…
A novel NPAM-silica was synthesized by an economic and environmentally friendly method. It was chemically cooperated into polyurethane with enhanced mechanical properties. Compared with N -phenylaminomethyl POSS/PU composites, the crosslinking junction states and the mechanical properties are different. NPAM-silica pr…
The optical properties of single colloidal semiconductor nanoparticles (NPs) are considerably influenced by the direct environment of the NPs. Here, the influence of different liquid and solid glycol matrices on CdSe-based NPs is investigated. Since the fluorescence of individual NPs varies from one NP to another, it…
We report herein for the first time, a novel crosslinking approach for the synthesis of grid-like zein nanofibres with SbQ (styrylpyridinequaternary) realized by a simple electrospinning process followed by thermal treatment and/or UV illumination.
Americanae nace como un proyecto conjunto que surge dentro de la Red Europea de Información y Documentación sobre América Latina (REDIAL), y que ha afrontado la Biblioteca de la Agencia Española de Cooperación Internacional para el Desarrollo (AECID). Esta nueva biblioteca virtual hace más accesibles los libros digita…
A comparative evaluation of the protective properties of chromate-free passivating formulations offered as an alternative to the widely used method for passivation of aluminum surfaces by Cr(VI) compounds has been carried out.It has been shown that the protective properties of the compounds tested in the system with t…
Ceria nanoparticles (CeNPs) have attracted considerable interest in the treatment of a number of conditions associated with increased production of reactive oxygen species (ROS), due to their unique antioxidant properties. We have previously demonstrated the attenuation in vasodilation after uptake of silica nanoparti…
A bispidine-like ligand involving four pyridine-N and three aliphatic-N donor atoms forms a bimetallic species with CuCl2 in which all seven N-donors are bound and which aggregates in the crystal through double chloride-bridging to give a tetranuclear unit. The magnetism of this solid can be interpreted in terms of a…
In this review, we introduce two powerful strategies for well-controlled interface. Interface chemistry engineering in electrode systems for electrochemical energy storage needs to integrate individual materials components to interface design and optimization.
We report the improvement of a CdSe quantum-dot-sensitized solar cell (QDSSCs) based on surface modification of Cu 2 S nanoparticle counter-electrodes (CEs).
The short-range interaction between Cr atoms was directly examined by scanning tunneling microscopy measurements on a Zn(0.95)Cr(0.05)Te film. Our measurements revealed that a Cr atom formed a localized state within the bandgap of ZnTe and this state was broadened for a pair of Cr atoms within a distance of ∼ 1 nm.
Variation in composition provides an additional degree of freedom in nanocrystals design.
A novel inorganic–organic core–shell nanocomposite, poly(N-isopropyl acrylamide) coated silica nanoparticles (PNIPA-g-FSNP), has been synthesized sonochemically for the first time following the principles of green methods. The sonochemical method eliminates the requirement for organic solvents, cross-linkers and hydro…
