The fused cages of dodecahedral and irregular-dodecahedral water cages with the maximum number of t1d hydrogen bonds were studied using the dispersion corrected density functional method.
The presence of OH groups on the surfaces of hydrophilic YbF 3 :Er 3+ mesocrystals not only rendered excellent dispersion in water, but also prohibited upconversion visible luminescence.
We report herein the synthesis of a dinucleotide bearing pendant porphyrins dedicated to adopt a pre-organized coformation with face-to-face porphyrins, and capable to self-organize in a stable sandwich type complexe with bidentate base such as DABCO. Earlier studies demonstrated that a peptidic linker does not provid…
We report the effect of growth temperature on the characteristics of Zinc oxide (ZnO) nanorods (NRs) synthesized by using a hydrothermal process. As the temperature was increased in the range of 70 − 200 °C, the diameter of the ZnO NRs varied from 20 to 45 nm, which might be associated with the fusing process. The sam…
A highly active AgMn/HZSM-5 catalyst was prepared for NH 3 removal by ozone catalytic oxidation and the reaction pathways were proposed.
Aqueous film forming foam (AFFF) is a very effective agent for firefighting hydrocarbon fuel fires. A study was conducted to develop a small-scale test for quantifying the drainage behavior of a synthesized AFFF formulation in accordance with the requirements of MIL-24385-F. The rate of drainage was measured to increa…
A group of titanium aminophosphate catalysts are synthesized and characterized in detail, and their catalytic application towards orange G dye degradation is studied.
:The genus Amphora is a large and widely distributed group of raphid diatoms, frequently found in fresh, brackish, and salt water environments from around the world. Presented here is the description and phylogenetic position of Amphora aliformis, a new species collected from the Banzu Flats, Tokyo Bay, Japan. This sp…
An investigation into the influence of ultraviolet-irradiation (UV) on wool fibers was performed using EPR Spectroscopy, FTIR-ATR and SEM-EDS.
MgFe 2 O 4 nanoparticles were prepared at different annealing temperature of 400, 450 and 500 °C. Transmission electron microscope image show that powders consist of ∼ 8 nm particles. Scanning electron microscope image show aggregation of particles and formation of large particles with size of 20-100 nm. Obtained nano…
Orientation-controlled 2D and 3D microarrays of Mn3O4 nanocuboids that were mediated by a conductive polymer were fabricated by evaporation-induced self-assembly of the oxide nanoblocks and subsequent polymerization of pyrrole in the interparticle spaces. Free-standing mesoporous polypyrroles (PPy) having chain- and s…
A unit allowing one to bend single-crystal samples for studying distortions of crystal lattices on X-ray topograms is described. The crystals are bent in accordance with the four-bearing geometry scheme. The bending radii can vary from hundreds to dozens of meters. The unit is intended for operation in A-3 X-ray spect…
SmCo/FeCo/SmCo trilayer was deposited with two different thickness configurations for soft phase (FeCo); 50 nm/10 nm/50 nm and 50 nm/25 nm/50 nm were deposited on Si (111) substrate and Ta (50 nm) seed layer by RF magnetron sputtering in a pressure, p, of 30 - 35 m Torr. After deposition the films were annealed under…
With dimension confinement, highly ordered core–shell CoFe 2 O 4 –BiFeO 3 nanocomposite arrays were obtained from the self-assembly phase separation.
To prepare silver nanoparticles (AgNPs) on infrared-transmitting crystal for surface-enhanced infrared absorption (SEIRA) measurements, a new strategy is proposed and demonstrated using electroless reduction of preformed silver chloride (AgCl) particles. Silver chloride precipitates were formed using an additive of po…
Encapsulation of [Fe(bipy)Cl 4 ][bipy.H] ( 1 ) (where bipy is 2,2′-bipyridine) in the Al-MCM-41 molecular sieve by using a “ship in a bottle synthesis” approach was achieved and the product was used as a nano-reactor in selective oxidation reactions.
Multi-core clusters have emerged as an important contribution in computing technology for provisioning additional processing power in high performance computing and communications. Multi-core architectures are proposed for their capability to provide higher performance without increasing heat and power usage, which is…
Cork-based composites are one of the well-known insulators. In order to improve the properties of these composites, especially thermal conductivity, aerogel nanostructures that have low thermal conductivity, thermal diffusivity, density and high compressive strength can be used as fillers. Because of the low thermal c…
Carbon-based materials containing heteroatoms, such as boron and nitrogen, are called heteroatom-substituted carbon alloys. Preparation and applications of heteroatom-substituted carbon alloys, particularly materials composed of boron, carbon and nitrogen (B/C/N materials), and carbon and nitrogen (C/N materials) are…
A practical and useful method was proposed and demonstrated through in situ observation utilizing a Raman spectroscope to systematically investigate the energy thresholds in the laser-induced carbonization of the compounds including sumanene derivatives.
