Abstract Surface temperature measurements are crucial in many applications; one promising approach is the use of thermographic phosphors. The temperatures of surfaces coated with such a material can easily be detected by measuring and evaluating the luminescence. In the present study, the CVD of chromium‐doped aluminu…
A conceptually simple method to calculate local and average pressure tensors in simulations of molecular systems with discrete particles is presented. The pressure originates from the linear momentum of the particles as well as from n-body interactions between the particles, and consists of one additive contribution f…
In this paper we consider a Cahn–Hilliard model endowed with the Wentzell boundary condition, which arises from the study of spinodal decomposition in binary mixtures confined to a bounded domain with permeable wall. Under the assumption that the nonlinearity is analytic with respect to the unknown dependent function,…
We created artificial proteins that contained repeats of a short peptide motif, Asn-Gly-Asx. In nature this motif is repeated within shell proteins as an idiosyncratic domain, while in vitro it has been shown to suppress calcification. The motif was embedded within peptide sequences that did or did not have the abilit…
Relationship between Chemical Structure and Helical Twisting Power in Optically Active Imine Dopants Derived from (R)-(+)-1-(1-Naphthyl)ethylamine, Fukuda, Kaoru, Suzuki, Hideyuki, Ni, Jin, Tokita, Masatoshi, Watanabe, Junji
To alleviate the problems associated with current copper interconnect technology, multi-walled carbon nanotubes (MWCNTs) have been proposed as a potential solution for on-chip communication in VLSI applications. In this paper, we develop an equivalent RC circuit model for MWCNT interconnect that captures both DC condu…
Abstract We present the synthesis of hyperbranched polymer grafted zinc oxide (ZnO) hybrid nanoparticles by self‐condensing vinyl polymerization (SCVP) via surface‐initiated atom transfer radical polymerizations (SI‐ATRP) from ZnO surfaces. ATRP initiators were covalently linked to the surfaces of ZnO particles, follo…
Pauflerite, β-VO(SO 4 ), is a new mineral species from the fumaroles of the Great Fissure Tolbachik eruption (GFTE), Kamchatka Peninsula, Russia. It was found in 1977 in the first cinder cone of the North breach of the GFTE. The mineral occurs as light green prismatic crystals up to 0.1 mm in length, associated with s…
Abstract Carboxymethyl‐chitosan (CMCS)/poly(vinyl alcohol) (PVA) blend film was studied for an application as a coating material in the site‐specific drug delivery system. Films were prepared by blending varying amounts of 4 wt% CMCS with 4 wt% PVA, casting and drying at 50°C for 24 h. The cross‐sectional SEM microgra…
The role of (Al,Si) disorder in the kinetics of albite dissolution is explored through parameterized Monte Carlo methods. Two dissolution mechanisms multilayer leaching and single-layer retreat. were tested on 48 albite test configurations. In simulations involving multilayer leaching, dissolution rates increased with…
Extended abstract of a paper presented at Microscopy and Microanalysis 2007 in Ft. Lauderdale, Florida, USA, August 5 – August 9, 2007
Catalytically enhanced growth of ZnMnTe diluted magnetic semiconductor nanowires by molecular beam epitaxy is reported. The growth is based on the vapor-liquid-solid mechanism and was performed on ( X-ray diffractometry, scanning and transmission electron microscopy, atomic force microscopy, photoluminescence spectros…
Scattering cross sections of radiation interactions with matter form the foundation for diagnostic x-ray imaging, nuclear medicine, and radiotherapy. These cross sections are typically presented as numerical charts in medical physics literature or complicated formulas in quantum electrodynamics literature. There seems…
A calorimetric investigation of the synthesized nanotubular hydrosilicates based on compounds of the variable composition (Mg,Ni) 3 Si 2 O 5 (OH) 4 with a chrysotile structure is performed on a Tian-Calvet high-temperature heat-flux microcalorimeter. The enthalpies of formation of the hydrosilicates from elements at a…
This work employs porous silicon as a gas diffusion layer (GDL) in a micro proton exchange membrane fuel cell (μPEMFC) and a micro direct methanol fuel cell (μDMFC). Pt catalyst is deposited on the surface of, and inside, the porous silicon to improve its conductivity. Porous silicon with Pt catalyst replaces traditio…
Atmospheric corrosion involves chemical, electrochemical, and physical processes in three phases (solid, liquid, and gas) and two interfaces (solid/liquid and liquid/gas). Because of inherent experimental and conceptual difficulties, scientific efforts to characterize this highly complex interfacial regime came relati…
In support of the Capillary Flow Experiments (CFE) program, several polymethylmethacrylate (PMMA) flight vessels were constructed. Some vessels used a multipiece design, which was chemically welded together. Due to questions regarding the effects of the experiment fluid (silicone oil) on the weld integrity, a series o…
25α:75β SiAlON composition was designed with different cations and at different molar ratios. Effect of the type of cations both on the composition and the type of intergranular phase investigated after gas pressure sintering and further post sintering heat treatment.
In the present paper, the fabrication and characterisation of typical high temperature Ni(Ti+Hf) alloyed thin films produced by simultaneous sputter deposition from separate elemental Ni, Ti and Hf targets are presented. Film composition, determined by energy dispersive X-ray spectroscopy, was controlled by adjusting…
Abstract The crystallization behavior of semicrystalline PEO homopolymer/triblock PS‐PEO‐PS copolymer blend system, which exhibited “Dry‐Brush” in the melt. A symmetric polystyrene–poly(ethylene oxide)–polystyrene triblock copolymer was blended with PEO homopolymer (h‐PEO) having the same molecular weight as that of t…
