In order to avoid calculation bias and increase calculation efficiency, convergence of the fission source distribution (FSD) in Monte Carlo simulations is important. Numerous analysis methods have been developed and used for checking the fission source convergence. However, such schemes have low applicability to Monte…
deposited SWCNT were sputter coated with Sn metal and thermally oxidized in air to form a SnO₂/SWCNT nanowire framework on SiO₂/Si substrate. Poly(acrylic acid) (PAA) was coated onto this scaffold through UV light-induced radical polymerization, which resulted in the final formation of hybrid composites. The structure…
The reactions of the methanol synthesis were conducted from the CO/CO2/H2 on the Cu-based catalysts using different solvent at 443 K and 3.0 MPa. The alcohol solvent had the activity in the low-temperature methanol synthesis reaction. The activity of the Cu-based catalyst with ZnO as carrier was higher than that of th…
Transfers of photoexcited electrons between poly(thieno[3,4- c ]pyrrole-4,6-dione)-based copolymers (push–pull type) and fullerene or nanocrystals were studied by light-induced electron paramagnetic resonance (EPR). EPR tracing methodology has been used: EPR signatures of the various species taking part in the electro…
Layered-inhomogeneous model of the refractive index profile, which includes primary and transition region is developed, the effect of the transition region with inhomogeneous distribution of the refractive index on the spectral characteristics of narrow-band filters depending on the angle and polarization is investiga…
Metal-chelate materials based on polycyclic aromatic ligands are attractive for tuning emission colors of organic light-emitting diodes (OLED). In this work, quinaldic acid (QA) and 8-hydroxyquinoline (HQ) were employed as organic ligands and the corresponding zinc complexes (Zn(HQA), Zn(QA), Zn(HQ)) were synthesized.…
The portable measurement instrument is designed and built to measure the dynamic magnetic properties of the soft magnetic materials. The measurement principle and sampling method are presented. The study shows the instrument can measure the different types of soft materials accurately at frequencies in the range of 20…
Homemade water in water cationic polyacrylamide (CPAM) emulsion was applied in cigarette paper pulp as dry strengthening agent with other strengthening agent. Good collaborative effect was achieved when CPAM was used in bleached wheat straw pulp with strengthening agent E and with cationic additives L as paper pulp st…
The controllable synthesis of special shape of nanoparticles with uniform size was most important for some special applications. In this work, we prepared silver nanocubes by Na2S-mediated polyol synthesis using AgNO3 as precursor, polyvinyl pyrrolidine(PVP) as capping agent and ethylene glycol(EG) as solvent and redu…
In order to select effective carbon black (CB) and matrix resin for fabricating semi-conductive shielding materials of XLPE insulated high voltage cable, the crosslinkable composites were prepared by melt blending different types of CB with three types of copolymer resin, and the crosslinking samples were compressed.…
The XRD patterns of Strontium Titanate (SrTiO3) prepared by direct current arc discharge plasma technique show that the well crystallized cubic structure. A Raman spectra study is performed to investigate SrTiO3 ceramics and powders compared with earlier investigations. The observed Raman spectra in this work have bee…
A novel flame retardant additive, DOPO-based polymeric phosphate (PFR-D), which simultaneously contained phosphorus and sulfur, was synthesized from 9,10-dihyro-9-oxa-10-phosphaphnanthrene-10-oxide (DOPO), POCl3 and bisphenol S. And the structure of PFR-D has been characterized by 1H-NMR, 31P-NMR and FT-IR. PFR-D was…
Photon buildup factors provide a convenient method for radiation protection professionals to calculate dose and exposure behind various shielding configurations. Examination of buildup factors can also provide insight into the behavior of photons in these shields. Recent work has developed dual-layer buildup factors f…
Electron beam (E-beam) curing by different total radiation doses (100, 200, 300 and 400 kGy at 10 kGy per pass) of functionalized maleimides (20%) [ N-(4-acryloyloxy phenyl)maleimide, N-(4-methacryloyloxy phenyl)maleimide and N-(4-cyanato phenyl)maleimide] is carried out using N-vinyl-2-pyrrolidone as the reactive dil…
As the atomic layer deposition (ALD) method is based on sequential, self-limiting surface reactions the precursor chemistry is the key to a successful processing of conformal high quality thin films. ALD precursor chemistry has traditionally been based on homoleptic compounds such as, but not limited to, metal halides…

During the last decades atomic layer deposition (ALD) gained a lot of interest for coating three dimensional structures with ultrathin conformal films. Although mainly applied on silicon wafers in microelectronics and solar, experimental efforts confirmed the technique is also applicable to powders and particles. This…
We present a system exhibiting extraordinarily long-range cooperative effects, on a length scale far exceeding the bulk correlation length. We give a theoretical explanation of these phenomena based on the mesoscopic picture of phase coexistence in finite systems, which is confirmed by Monte Carlo simulation studies.…
