In general, crystal growth proceeds by the addition of growth units at steps originating from dislocations or 2D nuclei. However, evidence exists that small 3D nuclei deposited on crystal faces can also act as step sources. In this study, the Monte Carlo method, based on the Kossel model, is used to study the fates of…
The generic structure of most high Tc superconductors is a stacking sequence of superconducting planes separated by so‐called charge reservoir layers. It is well known that carrier doping of these materials is achieved either by substitution of atoms or by nonstoichiometry in the charge reservoir layer. The alternatin…
Clays, due to their specific surface area and electrical charge density, are among the most active minerals in aquifers, oil and gas reservoirs, and tailings ponds. Important problems, such as limited yield of oil recovery during petroleum exploration, involve the interaction of process fluids with minerals which cons…
Abstract Zur Trennung chiraler Anästhetika werden für die Selektoren maßgeschneiderte kugelförmige Trägermaterialien benötigt. Dabei zeigen poröse Gläser besondere Eignung, da deren Textureigenschaften gezielt einstellbar sind. Durch die Nutzung einer speziellen Wirbelschichtapparatur sowie das Verfahren der ionotrope…
Oil sands in the Athabasca and Cold Lake regions of Northern Alberta form Canada’s primary source of energy reserves. Asphaltenes, a significant part of bitumen, are often considered to be the least valuable component of crude oil due to various factors such as difficulty in transporting and processing. Very few studi…
Abstract Dynamic fracture behaviour of AISI 1045 steel for compressor crankshaft was studied by experimental and numerical methods. True stress–strain relations of the material under different strain rates were measured, and dynamic constitutive model with consideration to strain‐hardening and strain‐rate hardening wa…
The present study reports the localization and interaction of thioglycolic acid (TGA) capped CdTe quantum dots (TGA@CdTe QDs) within the extracellular matrix (ECM) of Haematococcus pluvialis (Chlorophyceae) microalgae (HPM) after an incubation period of 5 min. Changes in the Raman spectrum of HPM induced by the adsorp…
Due to the substantial influence on the environment and health, there has been an intensifying environmental concern on sulfur dioxide (SO2) and nitrogen oxide (NO) discharge to the atmosphere all over the world. Flue gas of coal-fired power stations is major leading source for the emission of SO2 and NO. Cost-effecti…
Controlling the size of ordered nanorod aggregates in colloidal dispersions is a challenge. Here, we employ Brownian dynamics to explore the dependence of the nanorod aggregate size and structure on the molecular weight of a polyelectrolyte attached to one end of the nanorod and on the nature of the solvent. Upon incr…
Stress-strain relationships in semicrystalline hydroxylated polyethylene are studied using all-atom molecular dynamics simulations. Chain sizes ranging from 50 to 2000 carbons are gradually cooled from melt in order to obtain semicrystalline samples for pure, 4%, and 8% hydroxylated chains. Local orientational order o…
Nanomaterials with unique edge sites have received increasing attention due to their superior performance in various applications. Herein, we employed an effective ethylenediaminetetraacetic acid (EDTA)-assisted method to synthesize a series of exotic Bi 2 Se 3 nanostructures with distinct edge sites. It was found tha…
We investigate single crystals of ${\mathrm{Ce}}_{1\ensuremath{-}x}{\mathrm{Nd}}_{x}{\mathrm{RhIn}}_{5}$ by means of x-ray-diffraction, microprobe, magnetic susceptibility, heat capacity, and electrical resistivity measurements. Our data reveal that the antiferromagnetic transition of ${\mathrm{CeRhIn}}_{5}$, at ${T}_…
Energy dispersive X-ray spectroscopy within the scanning transmission electron microscope (STEM) provides accurate elemental analysis with high spatial resolution, and is even capable of providing atomically resolved elemental maps. In this technique, a highly focused electron beam is incident upon a thin sample and t…
A trigon structure formed by submonolayer gadolinium deposition onto Au(111) is revealed as a robust growth template for Co nanodot arrays. Scanning Tunneling Microscopy and X-Ray Magnetic Circular Dichroism measurements evidence that the Co nanoislands behave as independent magnetic entities with an out-of-plane easy…
An adopted mathematical model was developed to reduce the batch time required for the suspension polymerization of vinyl chloride in order to improve the productivity by continuous dosage of a fast initiator during polymerization reaction. The model was accompanied by a particle swarm optimization (PSO) algorithm, so…
We generalize the recently proposed steady-state density functional theory (SS-DFT) to spin-dependent cases and theoretically investigate the electronic and transport properties of a Mn-phthalocyanine molecule sandwiched between two graphene nanoribbon leads. The junction filters spin-up (minority spin) electrons whil…
Agglomeration effect on the electro‐magneto‐thermo elastic response of a hollow piezoelectric circular cylinder reinforced with carbon nanotubes (CNTs) is the main contribution of present work. The cylinder is subjected to an internal pressure, a distributed temperature field due to steady state heat conduction with c…
We report investigation of optical response in a single strand of a branched carbon nanotube (CNT), a Y-junction CNT composed of multiwalled CNTs. The experiment was performed by connecting a pair of branches while grounding the remaining one. Of the three branch combinations, only one combination is optically active…
Abstract Properties of film-forming dispersion (FFD) and emulsion film incorporated with palm oil containing soy lecithin at 50 % and 75 % (w/w, based on palm oil) and emulsified with different microfluidization pressures (6.89, 13.79 and 20.68 MPa) and pass numbers (2 and 4) were investigated. Microfluidized FFD cont…
