The mathematical modeling of a bolted joint with a Shape Memory Alloy (SMA) actuator ring is presented. In this way, phase transformation, constitutive and displacement compatibility equations are used. The obtained model is utilized to show how the application of the SMA actuator ring in the bolted joint can help the…
Abstract The study of polymer morphology continues to be the principal means of acquiring knowledge and understanding of macromolecular self‐organization. Longstanding problems of the nature of melt‐crystallized lamellae and spherulitic growth have been resolved, bringing understanding of how characteristic properties…
During conflict, Royal Navy personnel wear a two‐ply flame‐retardant (FR) “action coverall” (AC) and “anti‐flash” (AF) hood and gloves, made from Proban (Albright & Wilson's registered trademark) treated cotton. It is a widely held belief that extended wear, and repeated washing damages the Proban ® FR finish maki…
We have proposed a technique for fabricating carbon nanotube single-electron transistors using a focused ion beam (FIB). Wiring to a multiwalled carbon nanotube was formed by the ion-beam-assisted deposition of tungsten. Tunneling barriers were formed in the nanotube by ion beam etching. A drain current oscillation or…
Abstract Sub‐nanometre thick tin dioxide (SnO 2 ) films were grown on both amorphous Pyrex glass and crystalline CZ sapphire substrates using pulsed atomic layer metal‐inorganic chemical vapour deposition. The source materials, SnCl 4 and H 2 O, were introduced by pulsed doses as reactants into the cold reactor, and d…
Abstract Pale pink crystals of Nd 2 (SeO 3 ) 2 (SeO 4 ) · 2H 2 O were synthesized under hydrothermal conditions from H 2 SeO 3 and Nd 2 O 3 at about 200 °C. X‐ray diffraction on powder and single‐crystals revealed that the compound crystallizes with the monoclinic space group C 2/ c ( a = 12.276(1) Å, b = 7.0783(5) Å,…
Polyethylene terephthalate (PET) films were irradiated with 3 MeV proton beams at different fluences. The microhardness, electrical, thermal and structural studies were carried out using microhardness tester, LCR meter, thermogravimetric analysis (TGA) and FTIR spectroscopy. Vickers' hardness has been observed to incr…
The preparation, X-ray crystal structure and electrochemistry of a new poly-substituted air-stable tetrabenzoporphyrin iron(II) bis-pyridine complex (1) is reported.
Abstract The relation between the domains and domain boundaries of multiple twins of diamond were investigated by the electron back scatter diffraction (EBSD) method and high resolution transmission electron microscopy (HRTEM). Multiple twinned diamonds have two types of icosahedral morphologies. One is an almost perf…
Preliminary XRD, IR, Raman and SEM data indicate that porous glass-ceramic monoliths (pgc-LVCP) with skeleton of V(PO3)3 and Ca3(VO4)2 with three-dimensional network structure using an original Li2O-V2O3-CaO-P 2O5 glass as precursor was obtained. The pgc-LVCP is a promising porous host for integrated chemical systems…
The Brillouin light scattering was used to investigate elastic properties of the zinc blende, MBE-grown MnTe layer that was deposited on a (001) GaAs substrate covered by CdTe buffer layer. The three elastic constants of the zinc blende MnTe, namely c 11 , c 12 , and c 44 , were directly determined for the first time…
Uno de los componentes principales de las comunidades biológicas de los sistemas acuáticos es el zooplancton. Representa el eslabón entre el fitoplancton y los consumidores secundarios (peces y algunas aves). El conocimiento de su estructura permite caracterizar los sistemas acuáticos y conocer algunas de las interacc…
We report an easy procedure for isolating chromosome-clustered genes. By following this methodology, the entire set of genes belonging to the phenylacetic acid (PhAc; 18-kb) pathway as well as those required for the synthesis and mobilization of different polyhydroxyalkanoates (PHAs; 6.4 kb) in Pseudomonas putida U we…
Abstract Polymer blends comprising a polystyrene‐ block ‐polybutadiene‐ block ‐polystyrene (SBS) block copolymer and atactic homopolystyrene (hPS) were investigated using injection molded and solution cast samples. The morphology of the materials was studied by means of transmission electron microscopy (TEM) and scann…
Abstract Glasses from (GeSe 5 ) 1− x Ga x and (GeSe 4 ) 1− x Ga x ( x = 5, 10, 15, 20 at.%) systems have been investigated. X‐ray diffraction and IR scattering measurements have been carried out in order to elucidate the structure of the glasses. From the x‐ray diffraction data radial distribution functions (RDF) have…
We have measured structural, magnetic and, magneto transport properties of heterostructures consisting of La1–xCaxMnO3 ferromagnetic (FM) layers (x = 0.33) and antiferromagnetic (AF) layers (x = 0.67). FM/AF superlattices were grown by a high-pressure sputtering technique on (001) oriented SrTiO3 substrates. We have s…
Case-based reasoning (CBR) is an advanced reasoning technique simulating how hu mans routinely solve problems. There are several steps in CBR: presentation of a new problem, retrieval of the most similar cases from the database of cases, adaptation of the most similar old solutions, validation of the current solution,…
The overall goal of this research was to develop a single treatment process that will economically treat wastewater generated during chemical-mechanical planarization (CMP) processing of integrated circuits. Present treatment technologies require multiple steps, are expensive, and generate secondary waste streams requ…
Two commercially available amine-cured epoxy resin formulations were studied under different environmental conditions with regard to the surface tension evolution using axisymmetric drop shape analysis (ADSA). By employing a new strategy, ADSA was used to monitor simultaneously the surface tension and the density of t…
Summary The hydration number of lanthanides, Ln(III) (Ln = Sm, Eu, Tb, Dy), and Cm(III) in the extracted complexes with purified Cyanex301, Cyanex302 and Cyanex272 was investigated using time-resolved laser-induced fluorescence spectroscopy (TRLFS) and FT-IR spectroscopy. The results, in conjunction with the previous…
