The valence-shell excitations of nitrous oxide are studied by fast electron energy loss spectroscopy. From the spectra measured at 2.5 keV and scattering angles of 3.5°–8.5°, it is found that the asymmetric peak of the transition B 1 Δ can be well fitted by Haarhoff-Van der Linde function, while the symmetric peaks of…
ZnO-98% and Ga2O3-2% powder were consolidated by shock compaction technique, which uses a high performance explosive. The microstructural and electrical characteristics of ZnOGa2O3 compact with density of 97% and hardness of 220~250 Hv were investigated using SEM (Scanning Electron Microscope) and X-ray diffraction an…
Improvement in the quality of Liquid Crystal Displays (LCD) triggers a significant surge in the 3DTV market. A large segment of the 3DTV market has adopted active shutter glasses (active 3DTV). In this system, crosstalk is an important factor that affects the viewing quality of active 3DTV. This paper proposes a mathe…
Inter-residue pair contacts have been analyzed in detail for the four pairs of protein structures determined both by X-ray analysis (X-ray) and nuclear magnetic resonance (NMR). At contact distances < or = 4.0 angstroms in the four NMR structures the overall number of pair contacts are less by 4-9% and pair contacts a…
Struchium sparganophora (L.) Ktze (Asteraceae) is one of the vegetables equally consumed for medicinal purposes in the South Western part of Nigeria where it is used to treat a range of infections. The ethnomedical claimed use of the plant as an abortifacient crude drug was investigated on diethylstilboestrol treated…
Joint micellization of two amphiphilic diblock copolymers is studied by velocity sedimentation, transmission electron microscopy, electrophoretic mobility measurements, and static light scattering. One of the diblock copolymers is a strong polyelectrolyte (polystyrene- block -poly( N -ethyl-4-vinylpyridinium bromide))…
Recrystallization nucleates at heterogeneities. The impact of this on local texture and stress-strain response in hot worked magnesium is considered in the present paper. Two aspects of bulge nucleation during dynamic recrystallization are considered.
It is demonstrated that an efficient method can be created and used to determine the shape of grains in nanomaterials. This method relies on the discovered correlations between the amplitudes of different Bragg peaks for wideband X rays scattered in the sample on the grain shape.
We demonstrate uniformly and unidirectionally distributed pretilt characteristics of a liquid crystal cell fabricated via a substrate with a scan-directional slant nanosized surface groove pattern driven through an atomic force microscopic (AFM) tip that is continuously modulating the contact force in the scanning lin…
S-doped TiO2 nanomaterials (S-TiO2) synthesized by solid state and liquid state reaction route were used for the visible light degradation of Rhodamine B. The results show that at 20°C，pH=5, the rule of pseudo-first-order reaction and high catalytic activity were found in the visible light degradation of RhB on the S-…
We report enhancement in doping concentration of p- type SiGe by small addition of CrSi2into the matrix. P-type SiGe thermoelectric alloy was synthesized by melting the elemental powders with and without addition of CrSi2. The transport properties of both ingots were measured in temperature range of 25- 850 ̊C. The re…
In this paper, we employ the concept of probability for creating a cavity with diameter d in fluid along with the perturbation and variation approach, and develop an equation of state (EOS) for a hard sphere (HS) and Lennard—Jones (LJ) fluids. A suitable axiomatic form for surface tension S(r) is assumed for the pure…
In this paper, the resistance values of five different fineness cotton were tested under different moisture conditions, and the relationship among fiber fineness, moisture regain and its resistance were studied. With the increase of the moisture regain, the mass specific resistance and volume resistance decrease in an…
It was established experimentally that a critical value of the diamagnetic current, excited by an external magnetic field in a superconducting ring (with an inductance of about ∼10−6 H) with a Nb-Nb clamping point contact having the Josephson contact properties is a strictly periodic function of field strength, despit…
AlCl3was used as catalyst in the reaction. The reaction kinetics of aluminum and isopropanol was investigated in this paper. Metallograph showed that the surface of the aluminum bar had corrosive pitting. The reaction was zero order reaction when aluminum was overdosed. Reaction order was 0.75 when isopropanol was ove…
In this work, the heterocoaggulation of natural rubber latex (NRL) with polymer nanoparticles having positive charge on their surfaces was studied to prepare polymer nanocomposite. Firstly, poly [styrene-co-2-(methacryloyloxy) ethyl trimethylammonium chrorid (P(S-QDM)) nanoparticles were prepared by emulsifier-free em…
Through orthogonal analysis test analyzed three main process parameters(Acupuncture frequency, acupuncture number and acupuncture depth) on the influence of the preparation of Natural Bamboo Fiber/ Polypropylene fiber non-woven materials. The results show that when Acupuncture frequency, acupuncture number and acupunc…
Two methods are explained to exactly solve Maxwell’s equations where permittivity, permeability, and conductivity may vary in space. In the constitutive relations, retardation is regarded. If the material properties depend but on one coordinate, general solutions are derived. If the properties depend on two coordinate…
CoMoO 4 nanoscale materials were synthesized by a facile coprecipitation method and annealed at different temperatures with significant alteration of morphologies. The obtained CoMoO 4 materials were characterized by X-ray diffraction (XRD), FTIR spectroscopy, thermogravimetry and differential scanning calorimetry (TG…
The effect of the acceleration of carbon nanotube (CNT) growth from methane via modification of the gas composition with plasma discharge is studied by means of kinetic modeling. A model of CNT growth describing the detailed gas-phase and surface kinetics of hydrocarbons in catalytic chemical vapor deposition is used.…
