Organically modified silica (Ormosil) gels are three-dimensional matrices obtained by co-polymerizing tetraalkyl orthosilicates and organoalkoxysilanes through the sol-gel technology. Ormosil matrices are highly flexible with respect to macroscopic size and shape, as they can be prepared in the form of monoliths, laye…
NMR study of detonation nanodiamond (DND) 1 containing criticism of some results and findings reported in our review on the subject. 2 Based on their own results and citation of data consistent with, Schmidt-Rohr et al. 1,3 suggested the model of DND structure comprising an ordered diamond core covered by quite a thic…
Anodizing of ferritic stainless steel has been used for decoration purposes to obtain a barrier effect. The most commonly used electrolyte for this process is INCO (5M H<sub>2</sub>SO<sub>4</sub> + 2,5M CrO<sub>3</sub>). INCO electrolyte with glycerin addition induces the formation…
Iron (III) phthalocyanine complexes were employed for the first time as a mild and efficient Lewis acid catalyst in the selective oxidation of cyclohexene to cyclohexane-1,2-diol. It was found that the catalyst FePcOTf shown excellent conversion and moderate selectivity relative to other iron (III) phthalocyanine comp…
When the direction of flattening of a carbon nanotube changes during growth mediated by a metal nanoparticle, a carbon nanotetrahedron is formed in the middle of the carbon nanoribbon. We report the bending properties of the carbon nanotetrahedron/nanoribbon structure using a micro-manipulator system in a transmission…
ABSTRACT Researchers are actively developing shape memory polymers (SMPs) for smart biomaterials. This paper reports a new SMP system synthesized from biocompatible 2‐(dimethylamino) ethyl methacrylate (DMAEMA), butyl acrylate (BA) and tri(ethylene glycol) divinyl ether (TDE). Preliminary results show that the DMAEMA‐…
The direct method for computing thermal conductivity in nonequilibrium molecular dynamics gives rise to an artificial Kapitza resistance at the interface between thermostatted and unthermostatted regions. This resistance, which depends on the system size and the thermostat parameters, creates discontinuous jumps in th…
The permeability spectra of a multiferroic heterostructure composed of a FeCoZr thin film grown onto a [Pb(Mg 1/3 Nb 2/3 )O 3 ] 0.68 -[PbTiO 3 ] 0.32 (011) (PMN-PT) substrate are characterized as a function of an electrical field applied through the thickness of the substrate. When the sample is in an unpoled state an…
Unprecedented intense fluorescent emission was observed for a variety of flavin compounds bearing a perpendicular cyclic imide moiety at the C7 position of an isoalloxazine platform. A series of alloxan-substituted flavins was prepared selectively by reduction of the corresponding N-aryl-2-nitro-5-alkoxyanilines with…
An Al3Mn-type Al3(Mn, Pd) crystal and an Al–Mn–Pd decagonal quasicrystal (DQC) in an Al70Mn20Pd10 alloy are studied using a spherical aberration (Cs)-corrected scanning transmission electron microscope (STEM) with high-angle annular dark-field (HAADF) and annular bright-field (ABF) techniques, together with atomic-res…
Novel short-chain-length-long-chain-length polyhydroxyalkanoate (SCL-LCL-PHA) copolymer production was examined with Pseudomonas aeruginosa MTCC 7925 under supplementation of non-edible oils such as karanja, jatropha, mahua, and castor oils, and their respective cakes for cost reduction. Polymer yield reached up to 4.…
Polycarbosilanes were prepared via hydrosilylation polymerization of functional 1,1-diphenylethylene (DPE) derivatives (dimethyl-[4-(1-phenylvinyl)phenyl]silane (DPE-SiH) and 1-(4-methyloxyphenyl)-1′-(4-dimethylsilanephenyl) ethylene (DPE-SiH/OMe)). Both DPE-SiH and DPE-SiH/OMe were synthesized as monomers and then ut…
We have produced large numbers of hybrid metal-semiconductor nanogap antennas using a scalable electrochemical approach and systematically characterized the spectral and spatial character of their plasmonic modes with optical dark-field scattering, electron energy loss spectroscopy with principal component analysis, a…
Artificial neural networks (ANNs) are applied to correlate and predict physico-chemical, transport and thermodynamic properties of seawater. Values of these properties are needed in the design, simulation and optimization of processes in which seawater is used, mainly in the mining industry. Density, vapor pressure, b…
It provides comprehensive review and protocols for investigating nanoparticle interaction with erythrocytes, platelets, endothelial cells, plasma coagulation factors and plasma proteins forming so called "corona" around nanoparticles. Volume 3 is dedicated to nanoparticle interaction with and effects on the immune cel…
Basics of Polymers: Fabrication and Processing Technology constitutes one of the most important aspects of polymer science and technology. The performance of polymers is evolving into the most rapidly increasing volume of production. Polymers are an important commodity in the modern lifestyle. They are undoubtedly sup…
(ZrO 2 ) 1– x (Yb 2 O 3 ) x binary systems were investigated in the doping range of 0.02 ≤ x ≤ 0.12. Ytterbium‐doped zirconia powders were synthesized using the Pechini method. X‐ray diffraction ( XRD ) measurements showed that fcc ZrO 2 was stabilized for 8–12 mol% Yb‐doping rate. The produced Yb‐stabilized Zr (Yb SZ…
In this work sol–gel dip-coating technique was used to synthesize ZnO and ZnO/Al films. The influence of annealing regime and dopant concentration on the structural properties of ZnO and aluminum doped ZnO (ZnO/Al) films was investigated. The surface morphology and crystallinity of ZnO films were determined using atom…
The corrosion inhibition property of sodium lignosulfonate is investigated by three different independent monitoring techniques. These methods include weight loss measurements, electrical conductance and potentiodynamic polarization. Solutions with and without sodium lignosulfonate in 0.01 M HCl and 0.1 M HCl were pre…
We explore the dynamics of topological point defects on surfaces of magnetically responsive colloidal microspheres in a uniformly aligned nematic liquid crystal host. We show that pinning of the liquid crystal director to a particle surface with random nanostructured morphology results in unexpected translational dyna…
