Optimizing seeding efficiency, reducing delayed culture periods and mimicking native tissue architecture are crucial requirements for the development of seeding procedures in tissue engineering. In vascular applications, the tubular geometry of the grafts further hampers the efficient delivery of cells onto the scaffo…
A survey of the extracellular ATP levels of 86 heterotrophic bacteria showed that gram-negative bacteria of the genera Sulfitobacter, Staleya, and Marinobacter secreted elevated amounts of extracellular ATP, ranging from 6.0 to 9.8 pM ATP/colony forming unit (cfu), and that gram-positive bacteria of the genera Kocuria…
Paint and Coatings: Applications and Corrosion Resistance helps designers, engineers, and maintenance personnel choose the appropriate coatings to best protect equipment, structures, and various components from corrosion, degradation, and failure. The book addresses all factors - including physical and mechanical prop…
We present a density functional theory study of the structure and reactivity of Pt(110) under high loads of atomic oxygen. Surface structures in which the oxygen adsorbs on PtO2-like stripes along the Pt ridges of the Pt(110) are found to be highly stable. The structures become further stabilized when Pt atoms are eje…
Two strategies were employed to synthesize amino-functionalized multiwalled carbon nanotubes (MWNTs). In the first strategy, we grew poly(2-dimethylaminoethyl methacrylate) (PDMAEMA) from the surfaces of MWNTs by in situ atom transfer radical polymerization (ATRP), then allowed the polymer chains to react with methyl…
The Jouyban-Acree model has been used to predict the solubility of paracetamol in water-ethanol-propylene glycol binary and ternary mixtures based on model constants computed using a minimum number of solubility data of the solute in water-ethanol, water-propylene glycol and ethanol-propylene glycol binary mixtures. T…
The second-order nonlinear optical properties of a family of rare-earth-based single chain magnets are presented (using a fundamental field at wavelength λ = 766 nm), together with an analysis of the origin of the second-harmonic generation (SHG) process. By studying the fundamental crystal symmetries and the geometri…
This paper summarizes recent work in our groups on the factors that influence the formation of spider silks during the spinning process. The review encompasses: (a) extrusion variables that greatly affect the mechanical properties of the silk filaments; such as rate and temperature at spinning as well as the post-draw…
Negative values for the condensed Fukui function are identified as the key to designing molecules in which reduction of the molecule is associated with oxidation of one of the atomic centers, or vice versa. Sufficient conditions for negative condensed Fukui functions are derived, and metal complexes are identified as…
Surfactant-assisted synthesis of the oxysulfate Pr2O2SO4 with a large oxygen-storage capacity was studied with the aim of increasing the rate of redox cycles at lower temperatures. From an aqueous solution of nitrate, Pr-based surfactant mesophases templated by dodecyl sulfate anion (DS = C12H25OSO3−) were synthesized…
This article reports the mechanical properties of concrete prestressed by the Fe–Mn–Si-based shape memory alloys containing NbC that exhibit an excellent shape memory effect without the so-called ‘training’ treatment. A thermomechanically treated Fe–28Mn–6Si–5Cr–0.53Nb–0.06C (mass%) alloy was used for this purpose. Fo…
Automotive steels, Mild and Dual Phase590 (DP590) are characterized in tension at room temperature, using the quasi‐static and split Hopkinson bar techniques at various strain rates ranging from ∼10−3/s to ∼1800/s. Tension stress‐strain data for both the steels are analyzed to determine the Johnson‐Cook Strength model…
In the present study we have utilized the Allium cepa root tip meristem model to evaluate the cytotoxic and anti-mitotic activities of latex of Calotropis procera (DL) and podophyllotoxin. Standard cytotoxic drug cyclophosphamide and non-cytotoxic drugs cyprohcptadine and aspirin served as controls. Like cyclophospham…
Abstract—This paper simulates the expected device perfor-mance and scaling perspectives of carbon nanotube (CNT) field-effect transistors with doped source and drain extensions. The simulations are based on the self-consistent solution of the three-dimensional Poisson–Schrödinger equation with open boundary conditions…
Abstract Uncooled infrared focal plane arrays are being developed for a wide range of thermal imaging applications. Fire-fighting, predictive maintenance, process control and thermography are a few of the industrial applications which could take benefit from uncooled infrared detector. Therefore, to answer these marke…
Materials formulated as La(2-x)Sr(x)NiO(4+delta) (0 <or=x<or= 1) have been prepared and investigated by high-resolution neutron powder diffraction in order to correlate the structural variation induced by the incorporation of Sr into the crystal lattice with the electronic and thermal properties of each material. The…
This paper investigates an alternative explanation for widely reported paradoxical intracellular water properties. The most frequent biological explanation assumes water structure extending multiple layers from surfaces of compactly folded macromolecules to explain large amounts of perturbed water. Long range water st…
Bulk quantities of nanocarbons having pre-selected morphology can be synthesized in a simple and rapid microwave heating approach directly from conducting polymers.
The properties of conversion coating on magnesium can be closely related to its microstructure and composition. This study investigated the evolution and microstructure of phosphate/permanganate conversion coating on AZ31 magnesium alloy. Results show that increasing the solution temperature reduced the growth rate of…
This article presents an overview of recent studies on the behavior of carbon nanotube dispersions. The effect of attractive interactions on the percolation threshold is investigated. Contrary to this, we show that carbon nanotubes experiencing repulsive interactions exhibit a different phase behavior including liquid…
