The use of field portable X-ray fluorescence (XRF) spectrometry as a quantification tool for gypsum content in soils of West Texas and southern New Mexico, USA, was evaluated. Six sites were evaluated with gypsum contents ranging from less than 10% to greater than 90%. Samples collected from each site were scanned in…
Abstract The objective of this study was to design new, functional, nanostructured materials from the abundant clay mineral kaolinite, in spite of development problems with the interlayer chemistry of kaolinite because of its non-swelling properties. A particular goal of this work was to graft, in a controlled way, al…
The atomic-scale interactions of H atoms with hydrogenated amorphous carbon (a-C:H) films were identified using molecular dynamics (MD) simulations and experiments based on surface characterization tools. Realistic a-C:H films developed using MD simulations were impinged with H atoms with a kinetic energy correspondin…
We have investigated how the exchange bias and coercive field of NiFe/BiFeO3 bilayers on (001)SrTiO3 is affected by changes in substrate temperature, oxygen pressure, and film thickness for BiFeO3 deposition. Our results suggest that the exchange bias and the coercive field are mainly dependent on the roughness at the…
The thermal stability of p-type Ba8Ga16Ge30 clathrates grown from gallium flux has been tested by heat treatment in low pressure Ar atmosphere at 400, 600, and 800 °C. Significant gallium loss was observed for all samples during heat treatment. The treatment at 400 °C does not significantly change the sample propertie…
This paper presents the design, fabrication, and measurements of very high frequency kerfless linear arrays prepared from PZT film and PZT bulk material. A 12-microm PZT thick film fabricated from PZT-5H powder/solution composite and a piece of 15-microm PZT-5H sheet were used to fabricate 32-element kerfless high-fre…
Vielseitige Mikrogele: Emulsionen mit einem Volumenanteil bis 0.9 an innerer Phase sind mit weichen Mikrogelpartikeln als Stabilisatoren erhältlich. Die Adsorption der Mikrogele an der Grenzfläche hindert die Tröpfchen effizient am Zusammenlaufen, während im Überschuss vorliegende Partikel in der kontinuierlichen Phas…
The representative volume element (RVE) plays a central role in efforts to predict the effective thermo-physical and transport properties of heterogeneous materials. A quantitative definition of its size is proposed in this work. It is shown that RVE depends on the morphological or physical property being investigated…
The present work described the disorder induced magnetic properties of Sr2FeMoO6 (SFMO) samples. The crystal structure and magnetic order of SFMO samples with nanosized grains were studied using x-ray diffraction spectrum, scanning electron microscope morphology, and magnetic measurements. Thermal annealing of as prep…
Diel periodicity and effects of inorganic carbon (Ci ) and NO3 (-) on the expression of 11 key genes for primary carbon and nitrogen metabolism, including potential C4 photosynthesis, in the marine diatom Thalassiosira pseudonana Hasle et Heimdal were investigated. Target gene transcripts were measured by quantitative…
Abstract Mg‐Fe layered double hydroxide (LDH) with a Mg/Fe molar ratio of 3:1 was synthesized by using a coprecipitation method and the sorption removal of Pb(II) by the LDH sample from Pb(NO 3 ) 2 solution was investigated. It was found that Mg‐Fe LDH showed a good sorption ability for Pb(II) from Pb(NO 3 ) 2 solutio…
The use of drug cocktails has become a widely adopted strategy in clinical cancer therapy. Cytotoxic drug cocktails are often administered based on maximum tolerated dose (MTD) of each agent, with the belief of achieving maximum cell kill through tolerable toxicity level. Yet, MTD administration may not have fully cap…
In this paper the axisymmetric instabilities observed during the electrospinning of highly electrically conducting, viscoelastic poly(ethylene oxide) (PEO)/water solutions are investigated. In our theoretical study, a linear stability analysis is coupled with a model for the stable electrospun jet. The combined model…
The physical and microstructural properties of NiO‐ and Ni‐YSZ composite thin films deposited by pulsed‐laser deposition have been investigated for nanoporous anode electrodes of SOFC applications. An NiO‐YSZ thin film which was deposited at room temperature and postannealed at 700°C exhibited a fine porous structure,…
Abstract In spite of frequent observations, and of some important consequences for industrial applications, the glide motion of dislocations in non-octahedral planes of fcc metals and alloys remains rather poorly known, and not sufficiently considered for the analysis of mechanical properties. Following the pioneering…
A Kolsky apparatus with numerous modifications has been designed for mechanical characterization of materials at high strain rates. These modifications include employing a highly precise optical table, pillow blocks with Frelon®-coated linear bearings as bar supports and a laser system for better precision bar alignme…
The production of high quality single-walled carbon nanotubes (SWCNTs) on a bulk scale has been an issue of considerable interest. Recently, it has been demonstrated that high quality SWCNTs can be continuously synthesized on large scale by using induction thermal plasma technology. In this process, the high energy de…
The total cross section has been measured for the electron induced dissociation of trimethyl (methylcyclopentadienyl) platinum (IV) [MeCpPt(IV)Me3], a Pt precursor often used in focused electron beam induced processing (FEBIP), for incident electron energies ranging between 3–3 keV. Measurements were performed for the…
We have developed a new heating test to investigate the influence of dissolved copper (DBDS-Cu complex) and oxygen on copper sulfide generation in alkyl benzene insulating oil with dibenzyl disulfide (DBDS) added. The weight of the deposited and dissolved copper was systematically studied in atmospheres of nitrogen an…
We present a brief review of the most important efforts aimed at simulating single-walled carbon nanotube (SWNT) nucleation and growth processes using molecular dynamics (MD) techniques reported in the literature. MD simulations allow the spatio-temporal movement of atoms during nonequilibrium growth to be followed. T…
