γ-Cyclodextrin/alkylthiol inclusion compounds crystals as substrates for the formation and immobilization of gold nanoparticles produced by magnetron sputtering
(Kluwer Academic Publishers, 2015)
© Springer Science+Business Media Dordrecht 2014. In this work, we report the nanodecoration of microcrystals of inclusion compound (IC) of γ-cyclodextrin (γ-CD) that contain octanethiol, decanethiol and dodecanethiol. ...
The implications of laboratory Rn-222 flux measurements to the radioactivity in groundwaters: the case of a karstic limestone aquifer
(Elsevier B.V., 1997-11-01)
Laboratory time-scale experiments were conducted on Carboniferous Limestone gravels from the Mendip Hills area, England, with the purpose of evaluating the release of Rn-222 to the water phase. The specific surface areas ...
Thin films prepared from tungstate glass matrix
(Elsevier B.V., 2008-01-30)
Vitreous samples containing high concentrations of WO3 (above 40% M) have been used as a target to prepare thin films. Such films were deposited using the electron beam evaporation method onto soda-lime glass substrates. ...
Blue or red photoluminescence emission in α-Bi2O3 needles: Effect of synthesis method
(2018-01-01)
Monoclinic bismuth oxide (α-Bi2O3) has attractive optical properties and, therefore, its photoluminescence (PL) behavior has been increasingly explored. Besides this fact, the influence of synthesis methods on PL properties ...
Effects of chemical substitution on the structural and optical properties of α-Ag2-2xNixWO4 (0 ≤ x ≤ 0.08) solid solutions
(2016-01-01)
In this work, we investigated the effects of chemical substitution on the structural, electronic, and optical properties of α-Ag2-2xNixWO4 (0 ≤ x ≤ 0.08) solid solutions prepared by a facile microwave-assisted hydrothermal ...
Surface-dependent properties of α-Ag2WO4: a joint experimental and theoretical investigation
(2020-07-01)
Alpha-silver tungstate (α-Ag2WO4) has attracted much attention in recent years due to its unique crystal and electronic structures, which are suitable for a wide range of applications. This work presents a more realistic ...
Synthesis and evaluation of alpha-Ag2WO4 as novel antifungal agent
(Elsevier B.V., 2017-04-16)
Because of the need for new antifungal materials with greater potency, microcrystals of alpha-Ag2WO4, a complex metal oxide, have been synthetized by a simple co-precipitation method, and their antifungal activity against ...
Blue and red light photoluminescence emission at room temperature from CaTiO3 decorated with α-Ag2WO4
(2017-05-01)
CaTiO3 (CT) and α-Ag2WO4 (AW) semiconductors are widely known for their interesting electrical and photoluminescence (PL) properties. In this study, we decorated CT with AW for obtaining CaTiO3:α-Ag2WO4 (CT:AW), and ...
Stability of antibacterial silver carboxylate complexes against staphylococcus epidermidis and their cytotoxic effects
(MDPI AG, 2018)
© 2018 by the authors. The antibacterial effects against Staphylococcus epidermidis of five silver carboxylate complexes with anti-inflammatory ligands were studied in order to analyze and compare them in terms of stability ...
Development of films based on blends of gelatin and poly(vinyl alcohol) cross linked with glutaraldehyde
(ELSEVIER SCI LTD, 2011)
Both gelatin and poly(vinyl alcohol) (PVA) can be cross linked with glutaraldehyde (GLU). In the case of gelatin, the GLU reacts with each e-NH2 functional group of adjacent lysine residues, while for PVA, the GLU reacts ...
