The sediments in all kinds of containers in oily field ground processing system were called tank bottom oily sludge. In this paper, the characteristics of sludge were studied. The colloid and asphaltene can increase strength of the oily-water emulsion film which can lead to seriously oily emulsion. In view of this, th…
Pulp and paper industry is traditionally known to be a large contributor to environmental pollution due its largeconsumption of energy and chemicals. To reduce the chemical consumption, rate of delignification was increased bySchizophyllum commune in destructured sample of Dendrocalamus stictus, which was destructured…
The aim of this study was to observe the effects of drying temperature on the properties of deproteinized natural rubber latex (DNRL)/starch composite films. These composite films were prepared by simple mixing and then drying at different temperatures of 50, 60 and 70°C. Various parameters such as types (potato, sago…
Experimental creep crack growth data are generally obtained by following standard methods such as ASTM E1457-07 and subsequently characterised using the C* parameter. These data are then used in assessment procedures, such as R5, together with reference stress estimates of C* in the component, to predict creep crack g…
Extended abstract of a paper presented at Microscopy and Microanalysis 2013 in Indianapolis, Indiana, USA, August 4 – August 8, 2013.
The toughening of polystyrene (PS) by melt blending with natural rubber (NR) was prepared in a brabender plasticorder. Two kinds of processing had been used: (a) one-step mixing in which the three components of PS (60 wt%), NR (40 wt%) and maleic anhydride (MA) were simultaneously introduced in the mixer; (b) two-step…
Silt obtained from fractionated Bijoypur soil based on particle size (53~140?m) was characterized by SEM (Scanning electron microscopy), LIBS (Laser induced breakdown spectroscopy), XRD (X-Ray diffraction) and FT-IR (Fourier transform infra-red spectroscopy). pHzpc (Zero point charge pH) of silt was also determined by…
The objective of this research is to study the effects of alumina addition on the microstructure-mechanical property relationship and sintering behavior of yttria (3 mol%)-stabilized zirconia (YSZ) ceramics. Well-dispersed YSZ / Al 2 O 3 ceramics containing 10–40 wt.% Al 2 O 3 were prepared by solid state reaction met…
The nonlinear dynamic mechanisms of solid-phase formation with a phase transition region are studied under periodic and random fluctuations of the cooling-boundary temperature. It is theoretically shown that a mushy zone can form even at close liquid and cooling-boundary temperatures due to random temperature field fl…
Gastropods statoliths are biogenic structures of CaCO3, analogous to fish otoliths. Their application in sclerochronology is recent and may be advantageous comparing to the most traditional organisms used hitherto. Moreover, since elements bind within calcified structures, statoliths theoretically incorporate chemical…
Three fully optimized structures of 3,6-diamino-1,2,4,5-tetrazine-1,4-dioxide (LAX-112) dimers have been obtained with the density functional theory (DFT) method at the B3LYP/6-311++G level. Vibrational frequency calculations were carried out to ascertain that each structure is a minimum (no imaginary frequencies). Th…
The thermal conductivity of finite-length singlewalled carbon nanotubes (SWCNTs) was investigated using non-equilibrium molecular dynamics (NEMD) simulations. The temperature and diameter dependence of thermal conductivity was studied in this paper. In this work, thermal conductivity of SWCNTs with the length of 24.5n…
A new feedback optimization design method based on arithmetic sequence is proposed to design free-form optical systems for an extended LED source. Taken LED lens designed by this method as an example, we find that the design process is simple and high regional illuminance uniformity and high light output efficiency co…
Superparamagnetic Fe3O4nanoparticle with single phase has been synthesized successfully by a co-precipitation process. On the other hand, the effect of additive anhydrous ethanol in synthesis procedure was investigated for the magnetic properties of nanoparticles in this paper. The structure properties of synthetic Fe…
In this paper, a solution method to synthesize well-aligned ZnO nanowires (NWs) arrays on flexible substrates was reported. By investigated the growth of ZnO NWs on Polyimide (PI), it was found that the morphology of ZnO NWs arrays on PI could be controlled by adjusting the parameters. When the thickness of the seed l…
A weld repair technique to be used without post-weld heat treatment has been developed for use on grade 91 steel. The approach makes use of standard (non- modified) 9CrMo weld metal. The work has extended an approach used successfully on the low alloy steel ½CrMoV, which utilised a low strength 2CrMoL weld metal, to t…
ZnO:Cr layer was prepared by Cr ion implantation into ZnO bulk crystals. The structural, optical, and magnetic properties of the ZnO:Cr layer were studied with X-ray diffraction, photoluminescence, and superconductor quantum interferometer, respectively. The ZnO:Cr layer implanted Cr with a dose of 5×10 16 cm −2 remai…
Tensile and photodegradation behavior of poly (butylene succinate)/titanium dioxide nanoparticles (PBS/TiO2) composite films were investigated over a range of filler content 0-10 wt%. The surface of TiO2 nanoparticles was treated using propionic acid (C3H6O2) and n-hexylamine (C6H15N) order to disperse them into the b…
We propose a new approach to calculate the conformational free energy of a macromolecule in a compact stable state in implicit solvent. The free energy is evaluated with respect to an artificial reference system without internal interactions that is confined to a small well-defined multidimensional volume of a regular…
The effect of the annealing temperature on the I–V, C–I, and G–V characteristics and transparency of gallium-oxide films is investigated. The films are fabricated by the thermal evaporation of Ga2O3 powder on n-GaAs wafers. It is shown that the films which are amorphous after deposition crystallize upon annealing at t…
