This paper reports a facile one-step method for making undercut structures by dewetting of poly(methyl methacrylate) (PMMA) chloroform solution on an ice/water mold. The ice mold is prepared by filling the microchannels with water (micromolding in capillaries (MIMIC) method) and then freezing. The curving surface of w…
The tilt-casting method is used to achieve tranquil filling of gamma-TiAl turbine blades. The reactive alloy is melted in a cold crucible using an induction coil and then the complete crucible-mould- running system assembly is rotated through 180degrees to transfer the metal into the mould. The induction current is ra…
Among the rather widespread and fairly abundant minerals found on Earth is a crystalline mineral ore of iron called magnetite, which, unlike any other iron ore, is magnetic. Occasionally, pieces of this ore, called lodestones, are found which are permanently magnetized. Some specimens have been known to have such a st…
Abstract A Guest–Host system based on meta‐Nitroaniline (m‐NA) and recycled polystyrene (RPS) susceptible to generate nonlinear optically (NLO) active property such as second harmonic generation (SHG) has been prepared. Pure, sublimed, optical grade, crystalline m‐NA is used as a guest and RPS from the disposable pack…
The function of cytochrome c(554) of Vibrio parahaemolyticus has not yet been determined. We have determined the physicochemical properties and crystal structure of cytochrome c(554) at 1.8 A in order to help elucidate its function. The physicochemical properties and the tertiary structure of cytochrome c(554) resembl…
A note on rattlers in amorphous packings of binary mixtures of hard spheres
The deficiency of carbon nanotube (CNT) growth on temperature-sensitive substrates such as plastic tapes impedes the further progress in CNT electronics. We report a novel method that is able to offer the solution by selectively delivering energy via high radio frequency heating to carbon atoms for their catalytic ass…
We investigate the parametrization and optimization of thermal conductivity in silicon-germanium alloy nanowires by the cluster-expansion technique. ${\text{Si}}_{1\ensuremath{-}x}{\text{Ge}}_{x}$ nanowires are of interest for thermoelectric applications and the reduction in lattice thermal conductivity $({\ensuremath…
In the title compound, [Zn(C(8)H(5)N(2)O(2))(2)(H(2)O)], the Zn(II) ion is coordinated in each case by a carboxyl-ate O atom and an imidazole N atom from two different benzimidazole-2-carboxyl-ate (BIC) ligands and one water O atom in a trigonal-bipyramidal geometry. In the complex mol-ecule, the two benzimidazole pla…
The conventional approach for radiationless interference exploits the interference of evanescent components for the purpose of deep-subwavelength focusing and image formation. As a result, deep subwavelength feature size is achieved at the price of severe exponential decay of the field strength. We propose to overcome…
The PUPIL system is a combination of software and protocols for the systematic linkage and interoperation of molecular dynamics and quantum mechanics codes to perform QM/MD (sometimes called QM/MM) calculations. The Gaussian03 and Amber packages were added to the PUPIL suite recently. However, efficient parallel QM co…
"Los aspectos bioquímicos de los tepetates (capas volcánicas endurecidas) y suelos originados de materiales volcánicos han sido poco estudiados. En este trabajo se evaluó el flujo de CO2 (FC) y propiedades bioquímicas de suelos volcánicos representativos de México. Se eligieron cinco suelos en un transecto del volcán…
The ACs (R-1/2 and R-1/4) having two different textual and chemical properties are prepared from corn-based biomass precursor and evaluated together with a wood-based activated carbon (WAC) at room temperature using a gas chromatograph. The results obtained from the correlation studies indicate that the pore size dist…
A new diamine, 1,1-bis[4-(4-aminophenoxy)phenyl]-1-(4-hydroxyphenyl)ethane, was synthesized in three steps starting from 1,1,1-tris(4-hydroxyphenyl)ethane. New aromatic polyimides having hydroxy side groups were prepared from this diamine and various tetracarboxylic dianhydrides by the conventional two-step procedure…
A complete overview on all possible hydrogen bonding patterns of double helices with antiparallel and parallel strand orientation in alpha-peptide sequences is provided on the basis of ab initio molecular orbital theory. The most stable representatives belong to the group of antiparallel helices. The study on side cha…
Abstract We have developed a novel synthetic method that enables us to easily synthesize metal‐capsulated carbon nanotubes (CNTs) in a laboratory by using a combined technology of electrospinning‐metallization and microwave heating. These techniques greatly shorten the time for the synthesis of the CNTs in comparison…
Increasing rates of adult obesity and its negative health consequences are likely to become an increasing burden to the Canadian health care system. Consumers are looking for treatment options and often try the natural health products that are heavily promoted as safe, fast and effective. In this case report, MH, a 57…
Abstract Precipitation polymerization of styrene (St)–divinylbenzene (DVB) has been carried out using acetonitrile/1‐propanol mixture as the reaction media and 2,2′‐azobisisobutyronitrile (AIBN) as initiator. Monodisperse micron‐sized poly(St‐co‐DVB) microspheres with clean and smooth surface were synthesized in the a…
3-Dehydroshikimate dehydratase (DSD) is the first known enzyme catalyzing aromatization from 3-dehydroshikimate (DSA) to protocatechuate (PCA). Differently from cytosolic DSD (sDSD), a membrane-bound 3-dehydroshikimate dehydratase (mDSD) was found for the first time in the membrane fraction of Gluconobacter oxydans IF…
ZnO nanorods containing different hollow structures have been grown by a thermal evaporation-deposition method with a mixture of ZnS and SnO(2) powders as precursor. Transmission electron microscopy shows rods with rows of voids as well as rods with empty channels along the growth axis. The presence of Sn nanoprecipit…
