In recent years there have been tremendous advances in the fields of chemistry, physics and biology which have a direct impact on advances in biomaterials science. Many areas of healthcare depend upon the development of novel biomaterials. This book contains contribution from scientists who have made numerous innovati…
In the mean{ eld approximation, assuming the linear concentration dependence of the thermodynamic potential coe cients and taking into account the higher harmonics of spatial order parameter modulation in the incommensurate phase and interaction between order parameter and elastic deformation, the temperature and conc…
Carbon-silica dual phase filler (CSDP filler) differs in many aspects from the traditional fillers currently used in rubber compounds. According to the characterization with different analytical techniques, this material consists of two phases, the carbon phase with finely divided silica domains dispersed therein. In…
The surface state of as-prepared AlN powders produced by direct nitridation and carbothermal methods was characterized by X-ray photoelectron spectroscopy (XPS) and X-ray excited Auger electron spectroscopy (XAES). In the as-prepared AlN powders, small peaks assigned to imide and amide groups were detected in the N1s…
The engineering and material properties of controlled low-strength material (CLSM) can be altered through the use of air-modifying additives, thereby broadening potential end-uses for CLSM. Air-modified low-water content CLSM retains the compressibility, shear, load-bearing, and flowability characteristics of non-air-…
Solutions of celtulose (Cell) in dimethylacetamide (DMAc)/lithium chloride (LiCl) solvent are spun and annealed. The resulting fibers show various polymorphs with the different coagulants and annealing temperatures. Prior to annealing, as-spun fibers show Cell III morphology without differentiating the kind of coagula…
Abstract Reaction clusters serve to carry out reactions whose thermodynamic yield is too low for practical large‐scale application. They therefore play an important role in the economics of the process and can decisively control its environmental impact. Reaction cluster synthesis must address such economic and enviro…
A neural network model of nonlinear hysteretic inductors is presented. The proposed neural network model is shown to reproduce the dynamic scalar hysteretic behavior of the current-flux relationship. Moreover, the intrinsic characteristics of the neural network approach yield a model particularly suitable when depende…
Electropolymerisation of the 5-substituted indole monomers, 5-cyanoindole, indole-5-carboxylic acid, 5-chloroindole, 5-bromoindole and 5-methoxyindole results in a redox-active film consisting of a cyclic trimer and chains of linked cyclic trimer (polymer). The monomer, trimer and polymer species are fluorescent and h…
The spin-polarized linear muffin-tin orbital method has been applied to calculate the electronic structure of $({\mathrm{Fe}}_{1\ensuremath{-}x}{\mathrm{Ni}}_{x}{)}_{4}\mathrm{N}$ $(0<~x<~1.0)$. It is of interest that the band structure and the electronic and magnetic properties of $({\mathrm{Fe}}_{1\ensuremath{…
A previously developed method for determining elastic constants of single crystals from polycrystalline specimens was applied to cubic and tetragonal zirconia. The method is based on the orientation dependence of the lattice strain of a stressed specimen as measured by X-ray diffraction and also on Kröner’s equation r…
We have demonstrated the preparation of a new family of TS-FER products using organothermal synthesis.
Mononuclear iron carboxylate complex immobilized and isolated on a modified silica surface (1) catalyzes oxidation of hexane to a mixture of hexan-1-ol, -2-ol and -3-ol without ketone formation in the presence of mercaptan, acetic acid, triphenylphosphine and O2 at ambient conditions.
New liquid crystals induced by intermolecular hydrogen bonding between 4-[3, 4, 5-tridocyloxy benzoyloxy)-4′-stilbazole (3DBSZ) and malonic acid, succinic acid, glutaric acid, adipic acid, pimelic acid, suberic acid, maleic acid, fumaric acid, 3,4,5,-tridocyloxy-benzoic acid(3DBA) respectively were prepared, their liq…
Spherical particulate polysiloxanes are synthesised for the first time, chemically derivatised and employed as a support in molybdenum(VI) catalysed alkene epoxidation.
A thermoelastic problem for adhesively bonded assemblies with identical nondeformable adherends is considered. The objective of the analysis is to develop a simple stress model for the evaluation of thermally induced stresses and strains in the adhesive material due to its thermal expansion (contraction) mismatch with…
Magnesium anodization was examined in room temperature :EMIC and :DMPIC ionic liquids, where EMIC = 1‐ethyl‐3‐methylimidazolium chloride and DMPIC = 1,2‐dimethyl‐3‐propylimidazolium chloride. For all melts, the :organic chloride mole ratio was <1, yielding chloride‐rich ( i.e. , basic) compositions. The rate of magnes…
The high-temperature (573 K) adsorption of ethene, propene, propyne, carbon monoxide, and the high temperature co-adsorption of propyne–carbon monoxide have been studied over Pt/alumina and Ni/silica catalysts. The Pt catalyst was found to retain hydrogen from the reduction process, this hydrogen being released by eth…
In many polymer manufacturing processes, mass transfer operations between a high viscosity liquid and gases are applied, but mass transfer rates have been explained only using kLa. We measured kL for molten polystyrene and corn syrups by using a rotating cylinder with surface renewal action in which surface area was k…
The synthesis and structural characterization of the alkaline-earth thiolates [Sr(18-crown-6)(hmpa)2][SMes*]2 and [Ba(18-crown-6)(hmpa)(SMes*)][SMes*], displaying rare ion association modes with only one or no cation–thiolate linkages are presented.
