Based on the analysis of the chemical structure of polycarboxylate-type SPs grafted PEO side chains, as well as sulfonic and carboxylic acid groups, a kind of polycarboxylate-based SPs grafted varied PEO side chains were synthesized by using radical polymerisation techniques.The relative dispersing effectiveness of th…
Ni-B and Ni-Nb-B alloys are produced by mechanical alloying of mixtures of Ni, Nb, and B powders. X-ray diffraction analysis of the alloys indicates the formation of Ni(B) and Ni(Nb, B) solid solutions with nanocrystalline structure. The phase composition of the alloys is studied at different stages of mechanical allo…
In many countries, wheat straw is an abundant byproduct from wheat production in farming, only a minor portion of the straw is reserved as fuel, or raw materials for industry. In order to make good use of wheat straw, a series of materials based them are prepared by acylation grafting with propionic anhydride in a sol…
Abstract A new BriggsRauscher oscillating reaction with a tetraazamacrocyclic nickel(II) complex [NiL](ClO4)2 as catalyst and pentane‐2,4‐dione (pe) as the substrate is reported. The ligand L is 5,7,7,12,14,14‐hexamethyl‐1,4,8,11‐tetraazacyclotetradeca‐4,11‐diene. The experimental results indicate that iodine ion may…
Transparent conducting ZnO films are deposited by plasma-assisted deposition on glass and plastic substrates at temperatures as low as 50 °C. The effects of Ga doping and growth temperature on electrical properties are studied using Hall measurement and X-ray diffraction. Carrier density increases with Ga doping for b…
We present a reliable measurement process using a laser flash technique to measure intrinsic thermal diffusivity of vertically carbon nanotube (VACNT) arrays. The thermal diffusivity of VACNTs synthesized by a traditional water vapor-assisted thermal chemical vapor deposition process was measured, and shown to be ~30…
The reaction of binary eutectic formation from (Fe1 − y Ni y )S1 − z and γ-(Fe y Ni1 − y ) solid solutions was studied using directional solidification of a three-component melt in a quasi-equilibrium mode. An experiment was carried out to obtain a sample comprising a single-phase region and a two-phase region. Compon…
Electrospun TiC nano-felt with fiber diameters of ≈ 130 nm can be conformally transformed into carbide-derived carbon (CDC) after heat treatment in chlorine, report Hao Fong, Yuri Gogotsi and co-workers. The TiC-CDC nano-felts have been studied as flexible and binder-free electrodes for supercapacitors, and the result…
The chloride threshold to develop active corrosion of the reinforcing steel does not seem to be a unique value and it depends on several factors, such as concrete mix proportions, cement type, C3A content of cement, blended materials, water/cement ratio, temperature, relative humidity, steel surface conditions and sou…
A shaped charge with an axial channel is considered. The charge is initiated by an impact of an annular plate. As a result, the shaped charge is initiated at all points of the domain shaped as a ring. The impact plate material and parameters (velocity, thickness, width, and distance covered by the plate) that ensure s…
The mechanisms of electrochemical migration and consequent insulation failure in fine-pitch Cu wiring (line/space = 3 µm/3 µm) are investigated. A model in which the migration takes place in the presence of water in a phenol-based resin–resin interface between biased Cu traces is proposed. Replacing the bottom resin l…
Abstract Disk-like and flower-like ZnO nanostructures were prepared in alcoholic solutions with SDS-free and various sodium dodecyl sulfate (SDS) concentrations by a non-basic solution method. In all cases, the obtained crystals exhibited the crystal structure of wurtzite ZnO and photoluminescence at UV and green regi…
Amphiphilic porphyrin derivatives adsorbed onto silica nanoparticles via noncovalent interactions have been prepared and characterized. The organic-inorganic hybrids have been obtained by simply stirring a nanoparticle suspension into an aqueous solvent mixture of porphyrin aggregates. The systems obtained show good s…
Article Particularities of the formations of bainite and martensite/austenite phase in low carbon low alloy steels during continuous cooling was published on May 1, 2011 in the journal International Journal of Materials Research (volume 102, issue 5).
Double quantum well (DQW) structures consisting of a ZnCdSe well and a ZnCdMnSe well separated by a ZnSe barrier are grown with molecular beam epitaxy (MBE). The DQW structures are characterized by using X-ray diffraction measurement and simulation. Thickness of each well layer is designed so that the lowest energy le…
Experiment uses the Suspension Polymerization, under the dual oxidation-reduction system of H2O2-xanthate and H2O2-FeSO4initiating, the lipophilic- monomer of BMA is grafted on the frame of cotton fiber which prepares oil-absorbent fiber. It has studied the adsorption kinetics, adsorption transfer and isothermal absor…
Rheological and film forming properties of fish gelatin modified by transglutaminase (TGase) were investigated. The results indicated that the modified gels had higher gel strength of 101.4 g and 118.6 g with added TGase of 1% and 2 %, respectively. Elastic modulus (G'), viscous modulus (G'') of modified gels were sig…
The resol-type resin was prepared with a high yield from the liquefied products of walnut shell in phenol, which was reacted with formaldehyde under low alkaline conditions. The effects of reaction temperature and time on the yield and viscosity of the resol resin were investigated. Results showed that the optimum res…
The isomorphic substitution (IS) of Al for Fe can alter many properties of Fe oxide minerals, including their aqueous solubility. The resistance of these minerals to dissolution in soils can, in turn, influence the availability of Fe and the formation of new Fe oxides. In this study, the dissolution kinetics of synthe…
In view of the difficult separation problem of powder bentonite from solution in water treatment, the development of new type magnetic bentonite composite materials was studied. The adsorption performance of natural bentonite was improved by organic modification. The bentonite was magnetic modified by nano Fe3O4which…
