In this study, the aqueous solution method was employed to synthesize one-dimensional well-aligned ZnO nano-array on ITO glass substrate. We can find that the dimension of ZnO nanorod will changes with different growth temperature. X-ray diffraction patterns show that the nanorods are high-quality crystals growing alo…
The Einstein model to consider thermal effect in universal equations of state is modified, and an approach to solve parameters at absolute zero temperature from experimental data at a reference temperature is proposed and applied to the Baonza equation. The thermal Baonza equation is applied to study thermo-physical p…
The presence of foreign particles in the undercooled melt can influence the evolution of solidification structure and change the dendritic morphology. In this work, according to the KKS model, a hybrid phase field model for binary alloys, which takes into account the random crystallographic orientation, is developed t…
Modified stainless steel surfaces were fouled with whey protein solutions to study the deposition mechanisms and the effects of surface modification. Stainless steel samples were coated with diamond-like carbon (DLC) and titanium nitride (TiN). These surfaces are expected to present different surface chemistries to st…
Antimicrobial fibres were produced by the implementation of nanoscaled silver particles into a solution of cellulose and N-methylmorpholine-N-oxide (NMMO). Usage of particles with 80 – 140 nm and 5 - 20 nm grain size, which have a large surface, resulted in a much greater release of silver ions. Moreover, Lyocell fibr…
The vapor composition in the Bi-Sb-O system has been determined by Knudsen cell mass spectrometry. We have calculated the individual mass spectra of the Bi 3 SbO 6 , Bi 2 Sb 2 O 6 , and BiSb 3 O 6 molecules and determined the partial pressures of all the vapor species identified. Bi 3 SbO 7 and BiSbO 4 have been shown…
In the aim to define a structure NLO properties relationship, theoretical calculations have been used to investigate the role of different parts (substituents and π-system) of disubstituted conjugated systems based on naphthalene, cinnoline and quinazoline moieties.Using metallation and cross-coupling reactions we rep…
It is known that most enzyme‐facilitated reactions are highly temperature dependent processes. In general, the temperature coefficient, Q 10 , of a simple reaction reaches 2.0–3.0. Nevertheless, some enzyme‐controlled processes have much lower Q 10 (about 1.0), which implies that the process is almost temperature inde…
The deuterium atoms in both Ce2Ni7Dâ¼4 and CeNi3D2.8 occupy interstices in the CeNi2 structural slabs only, while the interstices in the bulk of the CeNi5 slabs remain empty. A considerable fraction of these deuterium atoms surround nickel in deformed tetrahedral configurations reminiscent of the [NiH4]4- complexes f…
Influence of short-time duplex heat treatment on the fatigue strength of α + β titanium alloy Ti-6Al-4V was investigated. When the alloy was solution-treated for 60s at 1203K and water-quenched, prior β phase was hardened since a part of this phase was transformed to acicular α' martensite phase. With subsequent aging…
The temperature dependence of the growth of cadmium selenide (CdSe) films prepared by galvanostatic electrodeposition in an aqueous acidic bath was examined. We observed a growth mode change at around , below which the growth rate is reaction rate limited and above which it is transport limited. Growth below deviates…
The fundamental propositions of the theory of local electrification of cavitation bubbles, which explains the phenomena of sonoluminescence (SL) and sonochemical reactions, are outlined. Key debatable questions are answered. It is shown that, unlike thermal theories, the local electrification theory agrees with a vast…
Electrochemical response of glass carbon (GC) and edge plane pyrolytic graphite (EPPG) electrodes was investigated using electrochemical impedance spectroscopy (EIS) method in three kinds of electrolytes, i.e., 0.1 M Na 2 SO 4 (aqueous solution), 0.1 M tetraethylammonium perchlorate (TEAP) (acetonitrile solution) and…
Using first principles calculations within the generalized gradient approximation, the structural stability of compound Mo-S clusters at subnanometer level is discussed based on results obtained for various Mo5Sn isomers with n=5–15. The symmetrical Mo-S bonds generally lead to higher stability, while the formation of…
Data on the synthesis of bifunctional octasubstituted phthalocyanines are reported. Some specificities of their electronic absorption spectra, thermal stability, and other properties, depending on the substituent nature and central metal ion, are revealed.
Surirella bifrons var. intermedia O.Mull. and Surirella fuellebornii O.Mull., including its infraspecific taxa, were re-evaluated using historical East African material collected in the early 20 th century from which Otto Muller described more than 100 new diatom taxa. In addition, mate- rial from the Hustedt Diatom C…
The surfaces of medical materials are coated with polymer molecules or drugs in order to functionalize the surfaces in ways such as imparting biocompatibility. However, in the case where the medical materials are inorganic, there is the problem that they will have poor adhesiveness to polymers and be liable to peel. F…
Ellipsometric characterization on the basis of multi-layered modeling is proposed to describe the optical and electrical property transients of hydrogenated films. In particular, two-step modeling is developed to make ellipsometric characterization on the yttrium film and the palladium capped yttrium film deposited on…
We report here the first electrochemically prepared surface-enhanced Raman scattering (SERS)-active silver substrates containing visible light-responsible TiO2 nanoparticles. The SERS-active Ag substrates with TiO2 nanoparticles were prepared by roughening the substrates using electrochemical oxidation–reduction cycle…
This report assesses various elements of the Washington State Department of Transportation (WSDOT) hot-mix quality assurance (QA) specification. Current WSDOT QA specifications contain measures of in-place density, asphalt content, and aggregate gradation for contractor pay and special provisions allow for additional…
