Standard ZnO nanorods with a diameter of ∼150 nm show poor field emission performance. In an attempt to dramatically improve the field emission properties, we developed two alternative methods: Th...
Porous single crystals of cubic Co3O4, NiO, In2O3 and CeO2 were fabricated using cage-containing SBA-16 and FDU-12 as hard templates, and characterized by X-ray powder diffraction, high-resolution transmission electron microscopy and N2 adsorption/desorption. Unsuccessful synthesis of non-cubic metal oxides implies th…
The optical constants and optical band gaps of the non-crystalline and crystalline zinc oxide (ZnO) thin films deposited by the spray pyrolysis method onto glass substrates at the different deposition times have been investigated by optical characterization method. The structure of the films was analyzed by X-ray diff…
A diverse variety of thiazyl radicals is known. Intense study of these heterocycles continues in the pursuit of molecule-based materials with novel, academically interesting, and technologically relevant properties. Coordination of these species to metal atoms and ions has focused primarily on the 1,2,3,5-dithiadiazol…
As a function of the ability of the solvent to behave as acceptor of halogen bonding, the NLO-phores under study give rise to microbeta(lambda) values ranging from +192 x 10(-48) esu to -465 x 10(-48) esu.
A proposal that high solid oxide fuel cell (SOFC) anode performance can be achieved by using a very thin, catalytically active functional layer, with a noncatalytic conduction layer, has been tested. An anode impedance of was obtained at in humidified using a Ag-paste conduction layer and a thick functional layer made…
In this mini-review recent applications of quantum dots in bioanalytics and biolabeling are discussed. The state-of-the-art of the field is summarized, some selected applications are highlighted, and future directions are suggested.
In order to find a correlation between cell adhesion, growth and biological response with different wettability, NIH/3T3 fibroblast cells were cultured on plasma-treated low-density polyethylene (LDPE) film generated with radio frequency. Different surface wettabilities (water contact angle 90-40 degrees ) were create…
Using molecular shape for the functional control of multicomponent systems is one of the challenges in the field of supramolecular chemistry. The well-known emission in the visible region of certain lanthanide (III) salts has found a new dimension by the controlled assembly of supramolecular architectures to enshroud…
TiO2 is a widely used manufactured nanomaterial and the opportunity for human exposure makes it necessary to study its health implications. Using murine models for inflammation, size effects of inflammatory response in instillation and acute inhalation exposures of TiO2 nanoparticles with manufacturers’ average partic…
During the last decade, the application of nanotechnologies for anticancer drug delivery has been extensively explored, hoping to improve the efficacy and to reduce side effects of chemotherapy. The present review is dedicated to a certain kind of anticancer drug nanovectors developed to target tumors with the help of…
A nanoscale FeIII-substituted polyoxotungstate [KFe12(OH)18-(alpha-1,2,3-P2W15O56)4]29- is synthesized starting from the trilacunary {P2W15} Dawson cluster and [Fe3(mu3-O)-(CH2=CHCOO)6(H2O)3]1+ to give a 2.6 nm tetrahedral cluster species and the 16 kDa cluster can be directly observed in solution as revealed by mass…
Yb–Er, Yb–Ho and Yb–Tm co-doped LaF3 IR-to-visible upconversion fluorescent nanocrystals with well-crystallized hexagonal phases were synthesized by a solvothermal technique, which was based on the decomposition of rare-earth trifluoroacetates. During this reaction the generation of fluoride ions and the nucleation of…
Herein, we describe a simple and inexpensive method for forming superhydrophobic cloths with the highest water contact angle of close to 180 degrees , in which normal commercial cloths serving as pristine materials are modified with suitable gold micro/nanostructures.
The sidewall functionalisation of carbon nanotubes using the standard nitric acid treatment can be greatly enhanced by first removing the amorphous carbon present in the sample.
Gold nanoparticles fully covered with triphenylene-based discotic liquid crystals (DLCs) were synthesized and dispersed in a columnar matrix. The thermophysical properties of these nanocomposites, studied using polarizing optical microscopy, differential scanning calorimetry and small angle X-ray diffraction studies (…
The combination of in situ X-ray absorption spectroscopy, X-ray diffraction and on-line catalytic data provided insight into the structure-performance relationship of a flame-made Pd/ZrO(2) catalyst during the total oxidation of methane: upon heating, a sudden reduction accompanied by sintering of the Pd-particles, le…

This article surveys and highlights the integration of nanometer scale carbon structures--in combination with chromophores that exhibit (i) significant absorption cross section throughout the visible part of the solar spectrum and (ii) good electron donating power--into novel electron donor-acceptor conjugates (i.e.,…
The electrochemical impedance Z and complex capacitance C for typical equivalent circuits were summarized systematically in order to support the frequency domain analysis of electric double layer capacitance (EDLC). In the present paper, the impedance and the complex capacitance were calculated in the case that the el…
