Recent advances in nanotechnologies stimulate the development of sensor systems based on nanocomposite materials. This review discusses the prospects and challenges of sensors coupled with functionally important for medicine hemoproteins and nanoscale materials. Authors summarized their own experimental results and li…
In this paper the influence of cross-links between collagen molecules on the elastic mechanical behaviour of biological collagen microstructures (namely fibrils and fibers) and soft tissues, such as arterial walls, is analyzed. A novel multiscale mechanical model is proposed, accounting for nanoscale mechanisms relate…
In order to establish the necessary conditions for producing high strength hot-dip Zn galvanized steel sheets for automotive use on a Continuous Galvanizing Line (CGL), a thermodynamic calculation of the selective oxidation behavior of Si, Mn-added high strength steel sheets was introduced, assuming a model in which a…
This clear and concise book focuses on the interrelationship of textile components to help students understand and predict textile properties and performance. Intended for undergraduate programs of colleges and universities that focus on fashion merchandising, fashion design, and interior design, Textiles: Concepts an…
¶ Dedicated to Professor Satya P. Moulik on the occasion of his 75th Birthday Abstract — The interactions of aqueous solutions of ionic surfactants and anionic polyelectrolytes with trivalent lanthanide ions, aluminium(III), iron(III) and chromium(III) are reviewed, with particular reference to phase behaviour and int…
Objective. After the COSMIC FSM method has been proposed, the issue of convertibility between traditional function points and COSMIC function points has arisen. Several studies have been performed, in order to evaluate whether a correlation between traditional and COSMIC FP measures can be established. Most of these s…
Several new dioxouranium(VI) complexes of Schiff bases [LH 2 ], derived from salicylaldehyde, substituted salicylaldehydes, 2-hydroxy-1-naphthaldehyde and 2aminothiophenol, have been prepared and characterized on the basis of their elemental analyses, IR and electronic absorption spectra and magnetic susceptibility me…
A thick-screen frequency selective surface (FSS) with circle slot elements is designed. Based on the moment method simulation, we investigate mainly the transmission properties of this structure under no dielectric condition, when some parameters, including the element diameter, unit distribution period and incidence…
Homo-polymers of 2-cinnamoyloxyethyl methacrylate (PCEMA) and block co-polymers with methyl-methacrylate (MMA) synthesized via copper(I)bromide/pentamethyldiethylentriamine-mediated atom transfer polymerization (ATRP) and microwave irradiation, under homo(co)polymerization conditions, are reported. Method 1 led to hom…
We demonstrate electrochemical polymerization of an aromatic conjugated monomer in a macroscopically aligned nematic liquid crystal. This method is a combination of employment of liquid crystal as the electrolyte solution, a rubbing technique, and electropolymerization. The resulting polymer film shows linear dichrois…
The interfacial bonding utilizing Ag 2 O-derived silver nanoparticles was evaluated using TEM observation and molecular dynamics simulation. The TEM observation reveals that the crystal orientation of the sintered silver corresponded to that of the gold substrate. This is considered that the epitaxial layer of silver…
Micelles as drug carriers are currently believed to be able to provide a set of important advantages: they can solubilize poorly soluble drugs and thus increase their bioavailability; they can stay in body (in the blood) long enough providing gradual accumulation in the required pathological areas (...
Flame spray synthesis (FSS) was used to grow TiO2-based nanopowders from which TiO2:Cr nanosensors were obtained. Structural properties of crystalline TiO2:Cr nanopowders at different Cr loadings (0.1-5.0 at.%) have been investigated. Material studies have been performed using standard methods: X-ray diffraction (XRD)…
UV-B photoirradiation of a neurotransmitter (serotonin) and aromatic amino acids (tryptophan and tyrosine) with oxygen results in DNA cleavage by generation of reactive oxygen species (ROS) as demonstrated by agarose gel electrophoresis with pBR 322 DNA, ESR and laser flash photolysis measurements.
The interaction between selected amino acid residues of the homodimeric enzyme triosephosphate isomerase from Trypanosoma cruzi with the inhibitor 3-(2-benzothiazolylthio)-1-propanesulfonic acid (BTT) was investigated by means of high level quantum chemical methods. The amino acids phe75A, arg71A and tyr102B from the…
A specific preparation procedure makes possible to obtain in one shot structural and compositional characterization of a buried interface at the nanometre scale using a micrometre scale probe. A specific example based on dispersive mu-XAS, micro X-ray absorption spectroscopy, shows that nearly-atomic scale changes in…
The depolymerization behavior of poly(ethylene terephthalate) (PET) to terephthalic acid (TPA) and ethylene glycol (EG) in high-temperature liquid water is examined in a batch reactor. PET is completely depolymerized in water for 10 min at 573 K. The total energy to obtain TPA and EG from a continuous PET depolymeriza…
The strain-dependent linear viscoelastic properties of several semidilute polyacrylamide-water solutions have been investigated by using our modified forced-oscillating torsion resonator. It is shown that these simple, semidilute uncross-linked flexible polymer aqueous solutions exhibit a strain softening behavior, as…
The influence of Cu-ion concentration in a concentrated electrolyte on the Cu removal rate and planarization efficiency (PE) of electrochemical mechanical planarization (ECMP) was investigated. With increasing Cu-ion concentration in the electrolyte, results show that the Cu removal rate significantly decreased becaus…
This paper looks into life extension of a group of transformers at Western Power transmission network. The transformers in question failed due to lack of enough clamping pressure on their windings which resulted in total failure of these transformers after close-in secondary faults.
