Ternary borate glasses from the system Na2O?CaO?B2O3 together with soda-lime-borate samples containing 5 wt.% of MgO, Al2O3, SiO2 or P2O5 were prepared. The obtained glasses were converted to their glass-ceramic derivatives by controlled heat treatment. X-ray diffraction was employed to investigate the separated crys?…
A facile in situ nanoparticle seeding method is reported to prepare MIL-101(Cr) films on alumina supports. The in situ seeding of MIL-101(Cr) nanoparticles was promoted by use of dimethylacetamide (DMA). The generality of this approach is further demonstrated for Cu(3)(btc)(2) films by using a (poly)acrylate promoter.
Dark matter has been introduced to explain substantial mass deficits noted at different astronomical scales, in galaxies, groups of galaxies, clusters, superclusters and even across the full horizon. Dark matter does not interact with baryonic matter except gravitationally, and therefore its effects are sensed only on…
A series of seven structurally-similar compounds with different pairs of RF groups were prepared, characterized spectroscopically, and studied by electrochemical methods (cyclic and square-wave voltammetry), low-temperature anion photoelectron spectroscopy, and DFT calculations (five of the compounds are reported here…
BACKGROUND: Gene therapeutic drug delivery approaches have been introduced to improve the efficiency of growth factors at the site of interest. This study investigated the efficacy and safety of a new nonviral copolymer-protected gene vector (COPROG) for the stimulation of bone healing. METHODS: In vitro, rat osteobla…
Conductive polyaniline nanofibers (PANInf) have been synthesized by interfacial polymerization and used to prepare composite electrodes with carbon black. Thus prepared PANInf/carbon black composite (PANInf/C) has been employed as an oxygen reduction catalyst in a microbial fuel cell. Higher electrocatalytic activity…

Natural radioactivity is a source of continuous exposure to human beings. The natural radioactivity due to the presence of 226 Ra, 232 Th and 40 K in sand samples collected from Ad-Dahna was measured by means of HPGe. The measured activity concentrations of radionuclides were compared with the worldwide reported data.…
Long aromatic polyamide chains are prepared from the corresponding monomers. The resultant polymer adopts a hollow helical conformation that is stabilized by intramolecular H-bonding interaction between side chains.
Color temperature (CT) is crucial to human physiology. A simple organic light-emitting diode with CT tunable between 1700 and 5200 K and a high current efficiency of 23.7 cd A−1 at 1000 cd m−2 is demonstrated. The wide CT span may be attributed to the use of a hole-modulation material with high triplet energy and high…
We have developed a drug-loaded poly(lactic-co-glycolic acid) (PLGA) microsphere-containing thermoreversible gelation polymer (TGP) (drug/PLGA/TGP) formulation as a novel device for implantation after surgical glioma resection. TGP is a thermosensitive polymer that is a gel at body temperature and a sol at room temper…
Highly porous carbon-doped TiO2(C-TiO2) has been prepared, for the first time, through a light-driven approach using crystalline titanium glycolate (TG) as the single-source precursor. Although the nonthermally prepared porous C-TiO2is amorphous, it shows a remarkable visible-light photocatalytic activity higher than…
We report herein lightweight, and economical dye-sensitized solar cells fabrication facilitated by an all plastic, metal free cathode consisting of poly(3,4-ethylenedioxythiophene).
We report herein an aqueous-phase catalytic process with palladium(0) nanoparticles (PdNPs) stabilized by semi-natural water soluble cellulose as catalyst. PdNPs stabilized by sodium carboxymethyl cellulose (CMC) in water were a very efficient and stable catalyst in the aqueous-phase catalytic process for the selectiv…
The thermal kinetics properties of pyrotechnic compositions consist of Ba(NO3)2+MgAl, Ba(NO3)2+MgAl+S, Ba(NO3)2+MgAl+KClO4 mixtures were investigated in this paper. Differential scanning calorimeter (DSC) had been employed to illustrate the reaction process of these pyrotechnic compositions. The apparent activation en…
A facile and straightforward approach for the preparation of graphene oxide-triggered self-assembly of natural tripeptide glutathione gels with different structures is reported. The morphologies of glutathione/graphene oxide gels could be controlled by adjusting the content of graphene oxide. The growth mechanism of t…
The ZrO2 thin films deposited on Si (100) were successfully synthesized by solgel process and deposited by using spin-coating technique.The structural properties of ZrO2 thin films were investigated by X-Ray Diffraction (XRD), Scanning Electron Microscope (SEM), Fourier Transform Infrared Spectroscopy (FT-IR), and ele…
Self-compacting concrete has to fulfil contradictory requirements of high flowing ability when it is being cast and high viscosity when it is at rest, in order to prevent segregation and bleeding. These requirements make the use of mineral and chemical admixtures essential for self-compacting concrete. High flowing ab…
Photofrin-mediated photodynamic therapy (PF-PDT) can induce cell apoptosis via the mitochondria/caspase-3 pathway. Here, we further investigate the mechanism involved in the mitochondrial apoptotic process induced by PF-PDT. A high-level intracellular reactive oxygen species (ROS) generation in mitochondria, mitochond…
The application of nanotechnology to medicine has enabled the development of functionalised nanoparticles that, acting as carriers, can be loaded with drugs or genetic material to be released with a controlled mechanism in specific districts of the organism. Even though nanomedicine is a relative new branch of science…
