A quantitative procedure of determination of kinetic and transport parameters for individual alloy constituents during anodic film growth on stainless steels in light reactor water is developed.It is based on in-depth compositional data for oxides obtained from ex situ analyses using Auger electron spectroscopy and X-…
Porous composite electrodes consisting of (BRO7) and (ESB20) were synthesized and characterized using impedance spectroscopy on symmetrical cells. Electrode performance was manipulated compositionally by varying the weight percent of each phase in the composite. Microstructural influences on electrode resistance were…
The SnS films were grown on glass substrates using the thermal evaporation technique at different substrate temperatures varied from , and their physical properties were studied with appropriate techniques. While increasing , the sulfur content in the films decreased and the Sn to S atomic percent ratio increased from…
This paper investigates the use of thermogravimetric analysis to study the kinetics of thermal degradation of ground tire rubber (GTR) obtained from reclaimed tires. We analyzed the composition of GTR and determined the content percentage of its components (volatile compounds, rubber, and ash) using thermogravimetric…
Ion Beam Science: Solved and Unsolved Problems (Part I, II) Sigmund P. Special‐Trykkeriet Viborg a‐s, Denmark, 2006. Price: 350 DKK (Danish Krone). ISSN: 0023‐3323. ISBN: 10 87‐7304‐330‐3; ISBN: 13 978‐7304‐330‐1, 376 pp. (Part I), 384 pp. (Part II).
Electrodeposition of SbTe thin films was investigated at room temperature, where amorphous deposits were obtained. The electrodeposition of Sb was found to be induced by Te, while the latter was not affected by the Sb. Detailed studies on this induced deposition were carried out by varying the Sb(III) and Te(IV) conce…
We discovered that phosphor emits green light under the application of a mechanical stress, a phenomenon known as mechanoluminescence (ML), and this green ML emission can be seen by the naked eye when pressing the sample. The ML showed a similar spectrum as photoluminescence (PL), which indicated that ML is emitted fr…
Multiwall carbon nanotubes (MWCNTs) and Co–Al layered double hydroxides (Co–Al LDH), as two electroactive materials, were integrated in one electrode to form a self-hybrid composite electrode on the basis that different materials should match correctly according to their respective charge-storage mechanisms. Our empha…
Abstract To improve the heat resistance of polyester‐based thermoplastic polyurethane (TPU), in the present work, polyamide 1212 (PA1212) was chosen as a modifier and a series of TPU/PA1212 blends with different compositions were prepared using a twin screw extruder. The solubility parameters, characteristic of chemic…
The effect of reduced size on the mechanical and elastic properties measured on $35\phantom{\rule{0.3em}{0ex}}\mathrm{nm}$ diameter Ni and Co nanowires is presented and discussed. The stresses induced in the nanowires due to the different thermal expansion constants of the metal and alumina change the magnetic propert…
Several elements were studied as potential A-site substituents in the perovskite system. The considered elements included , , , , , , , , and . The multicomponent oxides were prepared following a complexation-polymerization-pyrolysis method. The materials were characterized by X-ray diffraction, thermal dilatometry, a…
$X$-band electron magnetic resonance together with dc and ac magnetic measurements were employed for comparative study of magnetic ordering in bulk and nanometer-sized ${\mathrm{La}}_{0.9}{\mathrm{Ca}}_{0.1}\mathrm{Mn}{\mathrm{O}}_{3}$ single crystals. A dramatic difference between bulk crystal showing mixed magnetic…
It is demonstrated in electro-optic experiments that an external electric field of the order of 10;{5} V/m induces persisting texture transitions in a nematic phase formed by bent-core mesogens. The field-induced metastable state is identified by its optical and electric properties. After the field is switched off, th…
Morphological differences in semicrystalline polymers due to different crystallization conditions have implications for the chain motion. The local dynamics in the noncrystalline regions of solution-crystallized linear polyethylene is lower than in a melt-crystallized sample, but the opposite is observed for chain dif…
Effective atomic numbers for photon energy absorption, Z(PEA,eff), and for photon interaction, Z(PI,eff), have been calculated by a direct method in the photon-energy region from 1 keV to 20 MeV for biological molecules, such as fatty acids (lauric, myristic, palmitic, stearic, oleic, linoleic, linolenic, arachidonic,…
We used infrared spectroscopic ellipsometry to investigate the electronic properties of ${\mathrm{LaTiO}}_{3}/{\mathrm{SrTiO}}_{3}$ superlattices (SLs). Our results indicated that, independent of the SL periodicity and individual layer thickness, the SLs exhibited a Drude metallic response with sheet carrier density p…
Conventional amputation prostheses rely on the attachment of the socket to the stump, which may lead to soft-tissue complications. Intraosseous transcutaneous amputation prostheses (ITAPs) allow direct loading of the skeleton, but their success is limited by infection resulting from breaching of the skin at the interf…
Abstract Recently, there is an increasing interest in electromagnetic interference shielding due to the rapid increase in electromagnetic pollution and the wide use of commercial and military products. Conducting polymer composites were prepared in the presence of epoxy resin and plasticized carbon black (CB). The str…
We present a comprehensive study of surface composition and nanotribology for ultrananocrystalline diamond (UNCD) surfaces, including the influence of film nucleation on these properties. We describe a methodology to characterize the underside of the films as revealed by sacrificial etching of the underlying substrate…
We present a first-principles study of potassium atom adsorption on graphene and carbon nanotubes. Our calculations are carried out using density functional theory combined with the pseudopotential approximation. This study is, in part, inspired by inconsistent results reported for this system in literature. The adsor…
