Although mineralogic quantitative phase analysis (QPA) of the soil clay fraction can provide useful information for the improvement of soil management practices, QPA often requires a combination of several analytical techniques, which can be expensive and time consuming. One alternative that involves a single analysis…
Superparamagnetic iron oxide nanoparticles have been established as sensitive probes for magnetic resonance imaging (MRI). While the majority of specific nanosensors are based on sterically stabilized iron oxide particles, the focus of this review is on the use of very small iron oxide particles (VSOPs) that are elect…
We generalize the existing engineering approaches to modeling of high-speed penetration of projectiles into semi-infinite concrete shields and suggest a modified semi-empirical two-stage model that is applicable for bodies of revolution with a flat bluntness. At the first stage of penetration (cratering), the resistan…
The subject of dynamic fragmentation of materials has been of significant interest both from a fundamental point of view and in technological applications. In this review, we summarize the highlights of the theories and models developed to capture these phenomena and discuss some critical experimental observations tha…
Good or bad level design can make or break any game, so it is surprising how little reference material exists for level designers. Beginning level designers have a limited understanding of the tools and techniques they can use to achieve their goals, or even define them. This book is the first to use a conceptual and…
Film formation from aqueous suspensions of polymer nanoparticles is an important process in many environmental friendly applications and particularly for waterborne coatings. This process occurs via three mains steps: concentration, sintering, and interdiffusion. During the sintering step, the particles in close-packe…
Absorption isotherms at 323 K for the H−D−Pd system were measured by introducing H 2 and D 2 into Pd in sequence. The method using addition of isotopes to the system in sequence to investigate isotope exchange effects has not been previously reported. The equilibrium absorption pressure in the plateau region of the mi…
The behaviour of the Raman G' band of solubilized SWCNTs in aqueous solution is investigated with respect to ultrasonication time, surfactant type and centrifugation. The linewidth of the high frequency component of the G' band is shown to correlate with the degree of bundling in the solution. In particular, the linew…
Abstract The second‐order polarizabilities, transition moments, and density of states of aryldiazenido hexamolybdates derivatives were investigated by density functional theory (DFT). System 2 [Mo 6 O 18 (N 2 C 6 H 5 )] 3– has a considerably large second‐order polarizability, 14.50 × 10 –30 esu, and it is larger than…
Abstract In the present publication we report the results of dielectric spectroscopy investigations of two classes of materials – relaxor and dipolar glasses. As model relaxor was chosen (Pb 1–x La x )(Zr y Ti 1–y )O 3 (PLZT 100(x/y/1–y)). The real distribution function of the relaxation times f ( τ ) of the relaxor f…
Abstract All siloxane‐type siloxane–polyhedral oligomeric silsesquioxane [(HSiO 3/2 ) 8 , T 8 H ] copolymers were synthesized by the dehydrogenative condensation of T 8 H with diphenylsilanediol, tetraphenyldisiloxane‐1,3‐diol or silanol‐terminated polydimethylsiloxanes in the presence of diethylhydroxylamine followed…
A finite element method was developed to predict the effective thermal conductivity of particle filled epoxy composites. Three-dimensional models, which considered the effect of filler geometry, filler aspect ratio, conductivity ratio of filler to matrix, and interfacial layer were used to simulate the microstructure…
Serpentinitic landscapes are characterized by unusual plant species composition and vegetation patchiness. We hypothesized that soil extractable Ca content is correlated with vegetation Ca concentration and may contribute to the unusual vegetation characteristics. Eleven pedons from California were sampled within soil…
Bis(mexylamino)triazines have been identified as a family of compounds showing an exceptional propensity to form glassy phases as opposed to crystals. The particularities of this family of compounds are their ability to self-assemble through hydrogen bonding in well-defined patterns to form supramolecular aggregates w…
The patterning of carbon nanostructures by electron beam stimulated oxidation is described. Sputter deposited carbon thin films and carbon nanotubes are locally oxidized in a scanning electron microscope using injected water vapor. The resulting structures are examined with scanning electron microscopy and transmissio…
The experimental domain size scaling law in epitaxial ${\text{BiFeO}}_{3}$ films shows a different behavior from predictions of the conventional elastic domains: the (101)-type $71\ifmmode^\circ\else\textdegree\fi{}$ domains are much wider than that of (100)-type $109\ifmmode^\circ\else\textdegree\fi{}$ despite the la…
Adsorption isotherms of 3 selected paper-based packaging materials, that is, vegetable parchment (VP) paper, Kraft paper, and solid-bleached-sulfate (SBS) paperboard, were determined at 3 different temperatures (25, 40, and 50 degrees C). The GAB isotherm model was found to fit adequately for describing experimental a…
Polyaniline (PANI) can be deposited either on the surface or in the bulk of a microporous membrane by various chemical oxidative polymerization techniques. Each technique has distinctive effects on the PANI site and extent of deposition on the base membrane. In the present study, mixed cellulose ester (ME) membranes w…
The first applications in power ultrasonics were largely focused on ultrasonic cleaning baths, which rely on generating inertial cavitation, and the incorporation of ultrasonic excitation in manufacturing processes such as joining of plastics and metals. Since the early days of power ultrasonics there has been a rapid…
Direct evidence for C-O bond cleavage in the partial oxidation of 2-butanol on oxygen precovered Au(111) is provided using temperature programmed desorption (TPD) and molecular beam reactive scattering (MBRS) under ultrahigh vacuum (UHV) conditions. The oxygen precovered Au(111) surface can promote the partial oxidati…
