This work focused on the interactions which occur between ester solvents and alcohol solutes. The alcohols selected ranged from the simplest alcohol (methanol) to C10-alcohols, and solubility predictions in the form of infinite dilution activity coefficients were made using the Modified UNIFAC Dortmund group contribut…

At sufficiently high energies, the wavelengths of electrons and photons are short enough to only interact with one atom at time, leading to the popular %E2%80%9Cindependent-atom approximation%E2%80%9D. We attempted to incorporate atomic structure in the generation of cross sections (which embody the modeled physics) t…

To gain accuracy and, hence, physical reality of the data acquired by XRD measurements of fibre textures, a technique is elaborated to achieve experimental values, which are free of extinction effects. Its elaboration is based on combining basic definitions of the extinction theory and texture analysis. This technique…
Great attention has been paid to the palladium metal nanowires due to their wide potential application, in particular, as gas sensors and chemical reaction catalyst. In this work, the insulin fibrils were initially obtained by incubating the insulin peptides at 70℃ for 25 h. Then, the palladium oxide nanowires were sy…
The effects of ammonia on alignment of carbon nanotubes in an atmospheric pressure thermal chemical vapor deposition assisted by Ni were investigated. It was confirmed that ammonia is critical to the alignment of nanotubes at temperatures of 800–950°C. Both synthesis by C2H2 after ammonia pretreatment and synthesis by…
The recently developed Magnetically Applied Pressure-Shear (MAPS) experimental technique to measure material shear strength at high pressures on magneto-hydrodynamic (MHD) drive pulsed power platforms was fielded on August 16, 2013 on shot Z2544 utilizing hardware set A0283A. Several technical and engineering challeng…

Zusammenfassung Zur Überwachung von Faserverbundlösungen aus kohle- oder glasfaserverstärktem Kunststoff sind neue Ansätze notwendig. Der Artikel beschreibt ein elektronisches Messsystem zur integrierten Strukturzustandsüberwachung. Neben dem universalen Einsatz werden im ersten Teil der Aufbau des Systems sowie die m…
Zusammenfassung Magnetfeldmessung für wenig Geld findet heute in jedem Smartphone statt. Dieser Artikel widmet sich dem wissenschaftlicheren Einsatz handelsüblicher Kompass-ICs. So können diese Bausteine z. B. in der zerstörungsfreien Werkstoffprüfung oder bei Strommessungen verlässliche Messdaten liefern, auch wenn d…
Theoretical and numerical analysis is presented for kinetics of impurity segregation at the boundaries of a thin layer of substance dividing two different materials. Time dependences of boundary impurity concentrations and concentration profiles within the film have been obtained. Depending on the energy of impurity i…
Plasticity-induced fatigue crack closure associated with occasional mode II loading was simulated for two-dimensional middle-crack tension geometry by using the finite element method. When a single mode II cycle was superposed onto the steady-state mode I crack growth, the range of crack tip opening displacement, ΔCTO…
Elaborations in the field of chemical and abrasion resistant coatings and composite polymer materials by company Polymate LTD.-INRC (Israel) and its employees are reviewed. The main fields of advanced corrosion resistance materials are liquid and water based rubber compositions, hybrid nonisocyanate polyurethane coati…
Ethyl 1,2,4-triazine-5-carboxylates 6 were prepared by heating N,N-dimethylaminomethylene- or ethoxymethylenehydrazones 5 with ammonium acetate in acetic acid at 100°C. NMR studies confirmed the absence of their regio isomers (6-carboxylates), showing the high regioselectivity of this procedure.
The present review of the most recent patents outlines the progress made over the last several years in the search for evaporators of reactive metals. The miniaturization of modern devices using multilayer films brought about a new formulation of the requirements of evaporators of reactive metals (i.e., alkali and alk…
