The process of morphology evolution of nanorod, nanoparticle, and conventional as anode materials of secondary Zn battery on the charge-discharge cycling were investigated. with different morphology and particle size showed different electrodeposited growth habit, including the morphology retention on the initial stag…
Abstract Dimer acid‐based polyamides were synthesized by condensation polymerization in the absence and presence of monofunctional reactants. Acetic acid, oleic acid and propyl amine were used as monofunctional reactants. The influences of the equivalent percentage (E%) and type of monofunctional reactant on the physi…
An air nozzle having a axial angle of 50° and inner diameter of 2.2 mm was placed below the front roller nip in a ring frame, at various distances. Simulation of the airflow pattern inside the nozzle provides some useful insight into the actual mechanism of hairiness reduction. A CFD (computational fluid dynamics) mod…
A photoswitchable azobenzene-phthalocyanine-azobenzene triad has been synthesized and its electrochemical properties determined. Energy transfer among the subunits allows for modification of the E-Z ratio by selective excitation of the phthalocyanine moiety.
The mechanism and kinetics of chemical pickling of hot-rolled 304 stainless steel oxidized at high temperatures was investigated in HCl-based electrolytes with weight loss, corrosion potential, and electrochemical impedance spectroscopy (EIS) measurements. Corrosion products were characterized with scanning electron m…
Computational complexity of multiscale methods based on the first-principles energetics is analyzed. Computational cost of such methods is dominated by expensive first-principles determination of structural energies and atomic forces, including structural relaxations. Information integration is an opportunity to elimi…
The electronic structure of pure and Mg-doped wurtzite ZnO has been investigated by using first-principles ultrasoft pseudopotential method in the generalized gradient approximation. The calculation indicates that the band gap of ZnO broadens with increasing Mg-doping concentrations. Our work shows that the bottom of…
We carried out an experimental investigation to determine the static water absorption properties of terry fabrics. We tested 216 terry fabric samples, woven using 6 warp densities, 4 weft densities, 3 pile height and 3 different yarn types. It is shown that terry fabrics produced with two-ply ring-carded yarn have the…
Current polyamide 11 and 12 are lacking in fire retardancy and high strength/high heat resistance characteristics for a plethora of finished parts that are desired and required for performance driven applications. It is anticipated that nanomodification of polyamide 11 and 12 will result in enhanced polymer performanc…
In order to confirm the efficacy of liposomes as a drug carrier for atherosclerotic therapy, the influence of particle size on the distribution of liposomes to atherosclerotic lesions in mice was investigated. In brief, liposomes of three different particle sizes (500, 200, and 70 nm) were prepared, and the uptake of…
A novel multifunctional superabsorbent composite from acrylic acid (AA), acrylamide (AM), sodium humate (SH) and organo-attapulgite (organo-APT), PAA-AM/SH/organo-APT, was synthesized by aqueous solution polymerization, using N,N′-methylenebisacrylamide (MBA) as a crosslinker and ammonium persulfate (APS) as an initia…
Molecular Dynamics computer simulations of gold passivated nanoparticles in water are presented. We show that butanethiol passivated gold nanoparticles of ∼3 nm diameter exhibit weak de-wetting, similar to that observed in extended hydrophobic surfaces. The nanoparticle–water interface is characterised by a water dens…
A gold nanoparticle functionalized with substrates for alpha-chymotrypsin was fabricated to afford an enzyme modulator that exhibited enzyme-specific activation coupled with general inhibition of other proteases.
Divalent metal complexes of macrocyclic ligand 1,4,8,11-tetraazacyclotetradecane-1,8-bis(methylphosphonic acid)) (1,8-H4te2p, H4L) were investigated in solution and in the solid state. The majority of transition-metal ions form thermodynamically very stable complexes as a consequence of high affinity for the nitrogen…
A new strain of Agrobacterium tumefaciens (BST05) was found to grow on polyacrylonitrile (PAN; 13C labelled) converting the polymer to polyacrylic acid as shown by solid state NMR. When cultivated in a medium containing acetonitrile the bacterium produced nitrile hydratase and amidase activity. Activity recovery after…
The optical monitoring method is described to compensate for the thickness error of nonquarterwave layers of dielectric multilayer filters, using optical admittance during deposition. Stability is confirmed by computer simulation of random thickness error generation in layers. In addition, a band split filter consisti…
Two new ferromagnetic organic-inorganic hybrid materials [Co(II)3(H2O)6(pyz)3[W(V)(CN)8]2].3.5H2O (1) and [Co(II)3(H2O)4(4,4'-bpy)3[W(V)(CN)8]2].1.5(4,4'-bpy).6H2O (2) have been synthesised and characterised. The structure of the compounds have been investigated combining EXAFS (extended X-ray absorption fine structur…
Oxalate-based magnets have been known with several different crystallographic structures, from 1D to 3D, but with all of them based in metal ions with octahedral coordination. In this article we report a new bidimensional oxalate-bridged bimetallic magnet where the divalent metal appears heptacoordinated, which has st…
Mesoporous polymer–silica nanocomposite materials with redox functional groups such as ferrocene were synthesized via controlled radical co-polymerization inside mesoporous silicas and exhibited very high activity and selectivity towards catalytic hydroxylation of phenol.
Bismuth ruthenate pyrochlore was tested as a cathode in several bismuth oxide-based electrolyte cells. Erbium oxide stabilized bismuth oxide (ESB) , (BIMEVOX10, , Cu, Zn), and (BRO) were synthesized via solid-state reaction. ESB and BIMEVOX powders were pressed and sintered into dense pellets while BRO was deposited a…
