We studied the structural and luminescence properties of nanocrystalline RE <sub>3</sub> Ga <sub>5</sub> O <sub>12</sub> (RE = Gd, Y and Lu) garnets co-doped with 1 mol% of Nd <sup>3+</sup> and 10 mol% of Yb <sup>3+</sup> ions. The Nd <sup>3+</sup> sensitized Yb <sup>3+</sup> emission at 1025 nm is observed due to eff…
Uniform ZnO nanorod-Cu <sub>2</sub> O core–shell structures are fabricated and studied.
, but is partly restored by the tetragonal distortion. A direct band gap, close to 0.5-0.8 eV, is calculated for 0.25 ≤ x ≤ 2.25, justified by inter-metal transitions from Mn ions on octahedral sites.
Targeting a specific pathway aberrantly upregulated in cancer cells has shown immense potential in cancer therapy.
COSG was likely to be effective by increasing the phosphorylation level of Akt and promoting the membrane translocation of GLUT4, thereby increasing the glucose uptake of skeletal cells.
New gas-generating agents for air bags have been investigated. Ammonium nitrate does not give off harmful gases nor leave solid residues but goes through contraction and expansion during a series of phase transitions that cause structural damage within the material. In this study, potassium-nitratephase-stabilized amm…
Micro-structured thin-film electrodes were employed to investigate the capacitive behavior of nickel on yttria-stabilized zirconia (YSZ) electrolytes by means of electrochemical impedance spectroscopy. Electrodes with different shapes and electrode areas clearly showed a linear relationship between capacitance and the…
Burning perfluoro trichlorosilanes (R <sup>F</sup> ) treated paper leads to depolymerization of the crosslinked polysilane, distilling off liquid R <sup>F</sup> and emitting CO <sub>2</sub> and H <sub>2</sub> O as the only gaseous products.
Crystal growth by oriented attachment involves the spontaneous self-assembly of adjoining crystals with common crystallographic orientations. Herein, we report the oriented attachment of gypsum crystals on agitation to form stereoselective mesoscale aggregates.
The effect of Co complexes with a Schiff base ligand on the electrochemical corrosion behavior of 316 L SS in 0.1 M H2SO4 at 25℃ has been investigated at various inhibitor concentration using electrochemical techniques (impedance spectroscopy (EIS), polarization curves). Corrosion measurements indicate that Co complex…
White light with CIE coordinate (0.3553, 0.3338) was generated in the sample.
Three modes of emission, with different intensities and wavelengths were observed in tetraphenylethylenetetraamide 1 depending on the solvent, concentration and continuous irradiation with light, where intermolecular hydrogen bonds between amide units played a significant role. Limitation of the motility of molecule 1…
Shape-Memory Polymers (SMPs) have the ability to be deformed and memorize this deformation until an external activation stimulus (e.g., heat) is applied. Therefore, they have attracted great interest in many areas, especially for applications where reconfigurable structures are required (e.g., Shape-Memory (SM) stents…
The electrical conductivities of Sr2CoRO6 (R=Mo, Nb) under different oxygen partial pressures and their crystal structures were investigated. Their conducting mechanisms were proposed. X-ray photoelectron spectra revealed that the dominated oxidation state of Co2+ was in Sr2CoMoO6 but Co3+ in Sr2CoNbO6. The crystal la…
Pluronic based nano-particulate systems are innovative platforms for delivery of anti-cancer agents. These systems due to their pharmacological properties and suitable physicochemical characteristics are great opportunity for development cancer therapeutics. This mini-review tries to provide a more detailed overview o…

A bis(tetracene radical cation) connected by a dithiin-ring is obtained by two-electron oxidation of bisanthra-thianthrene, instead of the dithianonacene dication.
Представлены различные способы получения конструкционных материалов, обладающих функциональными свойствами, путем введения в матрицу полимерного композиционного материала (ПКМ) углеродных нанотрубок (УНТ). Показано, что на величину проводимости нанокомпозитов с углеродными нанотрубками оказывают влияние не только тип…
In present work we use NaI(Tl) detector in narrow-beam good geometry set-up for the gamma ray attenuation studies of some low-Z materials. The parameters such as mass attenuation coefficients, effective atomic numbers and effective electron densities, atomic cross-sections, electronic cross-sections of materials for g…
A series of novel red-emitting phosphors Mg <sub>3−x</sub> N <sub>2</sub> : <italic>x</italic> Eu <sup>2+</sup> (0 ≤ <italic>x</italic> ≤ 0.08) were successfully synthesized by solid-state reactions at low temperature.
