Here we report direct observations of spatial movements of nanodroplets of Pb metal trapped inside sealed carbon nanocontainers. We find drastic changes in the mobility of the liquid droplets as the particle size increases from a few to a few ten nanometers. In open containers the droplet becomes immobile and readily…
In this paper, nine different samples of YAIO3:Ce have been collected and analyzed. The light yield non-proportionality of each sample was measured and used to classify each sample as proportional or non-proportional. A variety of scintillation and optical measurements were conducted on each sample, and the proportion…
ZnO nanocrystals were successfully prepared under mild conditions by solochemical method from sodium hydroxide and zinc nitrate hexahydrate in 3 h refluxing. In this process the dependence of the morphologies, sizes and formation mechanisms of the ZnO nanocrystals on the reaction temperature was investigated. The samp…
We show that the experimental data for the action of ultrasonic waves on homeotropically aligned nematic-liquid-crystal cells reported by Kapustina, in Akust. Zh. 54, 900 (2008) [Acoust. Phys. 54, 778 (2008)] can be explained in the framework of the director-density coupling theory in the regime of low acoustic intens…
Magnesia-zirconia (MgO-ZrO2) support was prepared by a sol-gel method, and magnesium vanadate nano-catalysts supported on magnesia-zirconia (X-Mg3(VO4)2/MgO-ZrO2) were then prepared by a wet impregnation method with a variation of vanadium content (X = 6.6, 9.9, 12.8, 15.2, and 19.1 wt%). X-Mg3(VO4)2/MgO-ZrO2 nano-cat…
The present work is focused on the measurement of the rate and amount of gases evolved from various cores for aluminium casting. Specimens were selected from normal production at Carmagnola Plant of Teksid Aluminium, including furanic hot-box cores, phenolic shell-molding cores and phenolic isocyanate-urethane cold-bo…
In the present study, adsorption of Bismarck Brown (BB) dye onto iron oxide nanospheres (IONs) and modified IONs by HCl from aqueous solution was investigated. The IONs was synthesized by solvothermal method and then modified by HCl. The high magnetic properties of both adsorbents lead to facial separation from aqueou…
The Transition Rapidly exploring Random Eigenvector Assisted Tree (TRREAT) algorithm is introduced to perform searches along low curvature pathways on a potential energy surface (PES). The method combines local curvature information about the PES with an iterative Rapidly exploring Random Tree algorithm (LaValle, Comp…
Two coordination polymers, [Mn(dpts)(5-Br-ip)]n (1) and [Co2(dps)2(5-Br-Hip)4]n (2) (dpts = 4,4′-dipyridyltrisulfide, dps = 4,4′-dipyridylsulfide, 5-Br-H2ip = 5-Bromoisophthalate), have been hydrothermally synthesized by in situ generation of dps and dpts ligands from a 4,4′-dipyridyldisulfide (dpds) precursor in the…
The set of 42 diastereomeric structures resulting from various degrees of substitution of secondary –CH2– groups by amines –NH– within the adamantane skeleton are investigated. They are placed into a substitution‐reaction network viewed as a partial ordering, and the resultant reaction network (or Hasse diagram) displ…
We report the enhancement of the photoluminescence (PL) intensity of GaN-based light-emitting diode (LED) structures by using of a surface coating of polystyrene (PS)/silica (SiO2) core-shell nanospheres. PS/SiO2 core-shell nanosphere-coated LEDs show the highest PL intensity among various type LEDs. The relative PL i…
We report an observation of extremely long-lived spin states in systems of dipolar-coupled nuclear spins in solids. The "suspended echo" experiment uses a simple stimulated echo pulse sequence and creates non-equilibrium states which live many orders of magnitude longer than the characteristic time of spin-spin dynami…
The photo-catalytic degradation of chlorendic acid in the presence of TiO2 was conducted to investigate the reaction pathways and possible degradation products as a means of assessing the environmental legacies of polyesters that are designed with both chlorendic acid and TiO2 chemicals. Comparison of liquid chromatog…
Gallium nitride nanorods (GaN NRs) were grown by employing a low melting point Ni/In/Ga alloy via metalorganic chemical vapour deposition. A small growth temperature window was observed in the range of 720?765??C, which is lower than typical temperatures used for the growth of GaN NRs assisted by metal catalyst. Taper…
High temperature regime, 300-450?C for Mg-Al-Zn alloys, is currently used in primary processing, such as rolling and extrusion, as well as for secondary operation like forging. The knowledge of temperature and strain rate proper combination (processing window) as well as the microstructure evolution occurring during h…
12CaO x 7Al2O3, insulator (C12A7) doped indium tin oxide (ITO) (ITO:C12A7) films were fabricated using a radio frequency magnetron co-sputtering system with ITO and C12A7 targets. The qualitative and quantitative properties of ITO:C12A7 films, as a function of C12A7 concentration, were examined via X-ray photoemission…
A solvent extraction flowsheet for Pu partitioning, based on the acid split method without reductant, originally proposed by the Oak Ridge National Laboratory (ORNL), was tested for sodium-cooled fast reactor fuel reprocessing. To enhance resistance to nuclear proliferation, a flowsheet for co-processing was developed…
We investigate nano-sized double layer anti-reflection coatings (ARCs) using a TiO2 and SiO2 sol-gel solution process for mono-crystalline silicon solar cells. The process can be easily adapted for spraying sol-gel coatings to reduce manufacturing cost. The spray-coated SiO2/TiO2 nano-sized double layer ARCs were depo…
Graphenes have been considered suitable candidate materials for electrodes of energy storage devices such as lithium-ion batteries (LIBs) because of their outstanding mechanical, thermal and electrical properties. However, there are problems when using these carbon materials for electrodes because of their low electro…
We fabricated InSnZnO (ITZO) thin-film transistors (TFTs) with a high-permittivity (K) ZrO2 gate insulator using a solution process and explored the microstructure and electrical properties. ZrO2 and ITZO (In:Sn:Zn = 2:1:1) precursor solutions were deposited using consecutive spin-coating and drying steps on highly do…
