Texas Red dyes were used to partially label proteins for crystallization in both detergent and lipidic mesophases.Fluorescence detection of Texas Red can then be used to differentiate the protein crystals from salt crystals and other phase separations in the crystallization drop.Whereas ultraviolet light absorption an…
(LaNiO3)n/(SrMnO3)2 superlattices were grown using ozone-assisted molecular beam epitaxy. In situ reflection high energy electron diffraction and x-ray scattering has been used to characterize the structural properties of the superlattices, which are strained to the SrTiO3 substrates. The superlattices exhibit excelle…
With four-probe and laser light scattering techniques, we have studied the dependencies of the conductivity and the particle sizes of p-toluene sulfonic acid doped polypyrrole on the mechanical grinding time. As the chemically synthesized polypyrrole was mechanically grounded in a mortar from 0 to 8 hours, its conduct…
We present a comprehensive study of chiral fluctuations in the reference helimagnet MnSi by polarized neutron scattering and Neutron Spin Echo spectroscopy, which reveals the existence of a completely left-handed and dynamically disordered phase. This phase may be identified as a spontaneous skyrmion phase: it appears…
Using extraordinary Hall resistance ( R H ) measurements, the material dependence of thermally assisted magnetization reversal (TAMR) was investigated for microstructured multilayers of [Co (0.17 nm)/Pd (0.80 nm)] N with N = 7 and 20, which exhibit markedly different magnetic properties. The threshold values of the ex…
Einfluss der 475℃-Versprödung auf die Ermüdungseigenschaften eines Duplexstahls\n\nDie Kurzzeitfestigkeit von Duplexstahl wurde im lösungsgeglühten Wärmebehandlungszustand und unter Versprödungsbedingungen (100 Stunden Glühen bei 475℃) durch mechanische Untersuchungen, Raster- und Transmissionselektronenmikroskopie un…
In this article, we review the principles of macroscopic quantum electrodynamics and discuss a variety of applications of this theory to medium-assisted atom-field coupling and dispersion forces. The theory generalises the standard mode expansion of the electromagnetic fields in free space to allow for the presence of…
A testing program evaluating actual tank waste was developed in response to Task 4 from the M-12 External Flowsheet Review Team (EFRT) issue response plan.( ) The test program was subdivided into logical increments. The bulk water-insoluble solid wastes that are anticipated to be delivered to the Waste Treatment and I…
We set new regularities between the effective compressibility factor at the critical point (Z*) and unit compressibility line (Zeno-line) parameters. For classical liquids, Z* is the ordinary compressibility factor Z(c), but for quantum liquids Z* depends on the de Boer parameters. As a result, we show that a wide gro…
Divalent metal (barium, cadmium, calcium and zinc) soaps of rubber seed oil and their binary mixtures (Ba/Cd and Ca/Zn) and epoxidized rubber seed oil (4.5% epoxide content) and its admixtures with the single divalent metal soaps were evaluated as thermal stabilizer for dioctylphthalate plasticized PVC using changes i…
This work comprises a selection of 109, peer-reviewed papers on Engineering Research and Development: Innovations. It addresses a number of the scientific issues underlying innovations in Materials and Systems research at the global level, while paying particular attention to possible processes that may permit the rea…
The thermo-physical properties of some varieties of sawdust and some additives are presented. They are thermal conductivity, heat capacity and specific gravity. The methods of investigation used are Lee’s Disc Apparatus, heat balance and gravimetric method respectively. The sawdust specimens were obtained from six var…
Tools coated with TiBON films of varying boron concentrations were made, and the influence of boron concentration on tool wear was investigated. The TiBON coating film acts as a lubricant at high temperature. Tools coated with such films were applied to the machining of difficult-to-cut materials (Ti-6Al-4V and Incone…
Abstract AgGaSe2 thin films, changing the Ag/Ga ratio from 0.4 to 1.5, on glass substrates were successfully grown by vacuum evaporation method. Fundamental absorption bandedges were clearly observed except for Ag/Ga ratios of 0.4 and 1.5 in the optical transmittance spectra at RT. The optical bandgap increased with i…
Warpage deformation is an inevitable phenomenon as a cantilever sheet part is machined by combined saw milling tool. This problem affects machining quality obviously. In order to find the formation mechanism and a suitable solution, the paper carried out a qualitative analysis of the warpage causations, clarified the…
In this paper, the effect of porosity on reverse bias current–voltage characteristics of PtSi/por - Si (p-type) IR detector as a function of temperature is investigated. Our experimental data for two samples with different porosities (50% and 10%) at 300 K and 77 K are reported by Raissi et al.1 These data indicates a…
Micro carbide endmills suffer severe abrasive friction and impact wear in high speed milling of graphite. This paper focused on the study of the effect of Co content and WC grain size on the tool wear resistance of micro carbide endmills in high speed milling of graphite. The tool wear morphologies of cutting tools we…
To reduce the management cost and environmental load of water-soluble coolant, authors have been studying on a metabolic system for water-soluble coolant. More than 90% of waste water-soluble coolant is composed of water phase. If the oily additives and contaminants can be isolated from the waste coolant, the amount o…
Rubber seed oil monoglyceride was prepared by glycerolysis and characterized by chemical and spectroscopic methods. The monoglyceride was reacted with excess diisocyanates (hexamethylene -diisocyanate and toluene diisocyanate), and the network structures and molecular mass of the polyurethane were determined from swel…
