Epitaxial GaMnSb films with Mn contents up to about 10 at. % were obtained by deposition from a laser plasma in vacuum. The growth temperature T s during deposition was varied from 440 to 200°C, which changed the concentration of holes from 3 × 1019 to 5 × 1020 cm−3, respectively. Structure studies showed that, apart…
Macroscopic fracture parameters are investigated on 2D graphene systems containing atomic-scale cracks. In the discrete atomistic simulations the interatomic forces are described by the Tersoff-Brenner potential. Two methods to calculate the elastic energy release rates in atomic systems, the global energy method and…
Extract: The past few decades have witnessed technical advances that have introduced cell biologists and physicians to a new, dynamic, subcellular world where genes and gene products can be visualized to interact in space and time and in health and disease. The accelerating field of molecular imaging has been critical…
Abstract Model spent cetyltrimethylammonium bromide (CTMAB)-bentonite, and cetyl pyridinium chloride (CPC)-bentonite used for sorbing p -nitrophenol (PNP) from wastewater, as well as virgin CTMAB-bentonite and CPC-bentonite, were employed as the starting materials to prepare porous clay heterostructures (PCHs). The BE…
We present a new simulation methodology for analyzing programming characteristics of a chalcogenide based phase-change device, phase change random access memory (PRAM), which is a next-generation non-volatile memory. Using the new simulation methodology, we analyze the initialization of chalcogenide material (ICM) of…
Dysprosium titanate (Dy 2 TiO 5 ) based ceramic is one of the control rod materials for thermal reactors. This ceramic has been prepared by conventional mixing and calcination technique. The formation of Dy 2 TiO 5 phase from the Dy 2 O 3 –TiO 2 starting mixture has been found to be a two‐step process. In the first st…
Inhibition for carbon dioxide (CO2) corrosion of N80 steel by quaternary alkynoxymethyl amine (IMC-80-Q) in 3% sodium chloride (NaCl) solution was investigated under static and flowing conditions using a modified rotating disk apparatus. The effects of flow velocity and concentration of inhibitor on inhibition perform…
The flow from line and point sources through an inclined fibrous sheet is studied experimentally and theoretically for wicking from a saturated region and flow from a constant-flux source. Wicking from a saturated line generates a wetted region whose length grows diffusively, linearly or tends to a constant, depending…
Highly (101)-oriented p-Ag 2 O thin film with high electrical resistivity was grown by rapid thermal oxidation (RTO) on clean monocrystalline p-type Si without any post-deposition annealing. From optical transmittance and absorptance data, the direct optical band gap was found to be 1.46 eV. The electrical and photovo…
To elucidate determinants of differences in thermostability between mesophilic and psychrophilic monomeric isocitrate dehydrogenases (IDHs) from Azotobacter vinelandii (AvIDH) and Colwellia maris (CmIDH), respectively, chimeric enzymes derived from the two IDHs were constructed based on the recently resolved three-dim…
Several compounds of the Na 2 (Mn 1-x Fe x 2+ ) 2 Fe 3+ (PO 4 ) 3 solid solution have been hydrothermally synthesized at 400 °C and 1 kbar; pure alluaudite-like compounds have been obtained for x = 0.00, 0.25, 0.50, 0.75, and 1.00. Rietveld refinements of the powder X-ray diffraction patterns indicate the presence of…
In this study, the Hagen-Poiseuille formula has been used to establish the equation expressing the relationship between permeability of interyarn interstices and fabric structures. Validation with experimental data shows that interyarn porosity has a very strong influence on fabric permeability. The stepwise regressio…
The local stability of a cylindrical liquid channel or filament deposited on a planar homogeneous substrate is studied in the framework of an effective interface model including the line tension of the three phase contact line. We discuss the stability with respect to transversally symmetric and antisymmetric deformat…
Cleaning of nanoparticles (< 50nm ) is becoming a major challenge in semiconductor manufacturing and the future use of traditional methods, such as megasonic cleaning, is questioned. In this paper the capability of megasonic cleaning to remove nanoparticles without inflicting damage to fragile structures is investi…
ABSTRACT: Cod sausages with added chitosan (1.5%), a chitin‐derived polysaccharide from shrimpshells, were obtained by high‐pressure treatment (350 MPa/7°C/15 min). Color, rheological properties, biochemical indices (pH, total volatile basic nitrogen, thiobarbituric acid index), and microbiological counts (total bacte…
Fe3+‐montmorillonite clay catalyst was used for the first time for pyrroles preparation by Paal–Knorr condensation. The features of this catalytic system are improved yields, mild conditions, a simple procedure, and high catalytic efficiency. The catalyst could be easily recycled and reused for three times without vis…
Frequency-domain analysis of ultra-high frequency (UHF) signals for source identification of partial discharge (PD) occurring in SF/sub 6/ inside gas-insulated substation (GIS) has been widely covered in literature. In this, Fast Fourier Transform and Discrete Wavelet Transform based techniques have been extensively a…
Abstract The use of textile reinforcements for polymer composite components has become a common practice due to the favourable material costs and labour requirements compared with traditional unidirectional prepreg composites, and the high stiffness and strength compared with the use of randomly orientated reinforceme…
Coupling of carrier wave frequencies up to 95 kHz (within the European CENELEC A-band) for online diagnostic data transfer in medium voltage cables is studied. Inductive and capacitive signal coupling is considered not only on basis of technical performance, but also on basis of practical aspects. The effectiveness of…
Abstract Several titanium isopropoxides have facilitated the ring opening polymerization of l ‐lactide (LA) and rac ‐lactide in toluene solution at various polymerization temperatures via a coordination insertion mechanism. Depending on catalysts, the controlled/living poly( l ‐lactide), or the heterotactic‐biased pol…
