Effects of Variable Saturation on the Thermal Analysis of the Engineered Barrier System for a Nuclear Waste Repository
The effects of the resaturation process occurring in the buffer on the analysis of temperature distribution in the engineered barrier system of a nuclear waste repository were assessed. The assessment was performed using the TOUGH2 computer code, which analyzes the multidimensional fluid and heat flows of the multipha…
Tuning the Emission Color of Conjugated Polymers via Oxidation Copolymerization of Fluorene and 3,4-Ethylenedioxythiophene
In this paper, 3,4-ethylenedioxythiophene (EDOT)units are introduced to polyfluorene via chemical oxidation polymerization. FTIR and 1 H NMR spectra results confirm that the products are copolymers. Elemental analysis results show that the EDOT content in obtained copolymers increases as the feed ratio of EDOT/fluoren…

The crystal structures of [CuL](NO3)(ReO4) and [CuL](ReO4)2 (L is 4,6,6-trimethyl-1,9-diamino-3,7-diazanon-3-en) are studied. The square coordination of the copper atom in [CuL](NO3)(ReO4) is completed to a distorted octahedron by two oxygen atoms: Cu…O (ReO 4 − ) 2.393 Å and Cu…O (NO 3 − ) 2.685 Å, and that in [CuL](…
Inverted Organic Solar Cells with ZnO Nanowalls Prepared Using Wet Chemical Etching in a KOH Solution
We report on the photovoltaic (PV) performances of inverted organic solar cells (IOSCs) that were fabricated from PCBM:P3HT polymer with a ZnO thin film and ZnO nanowalls as electron transport and hole block layers. ZnO thin film on ITO/glass substrate was deposited using a simply aqueous solution route. ZnO nanowall…
Studying The Performance of Men’s Socks
Socks are one of the most important accessories, which have many kinds of blend composition, design, style and construction. In this study, an investigation was conducted to identify the blend composition ratio, stitch density, thickness, weight per unit area and air permeability to explore their effects on the durabi…
Effect of Grain Size on Oxidation Behavior of Fe-40Ni-15Cr Alloys
Abstract Fe-40Ni-15Cr alloys with different grain size were prepared by powder metallurgy (PM) and mechanical alloying (MA) through hot pressing technique. Their oxidation behavior was examined at 1073–1173 K in 1.01 × 10 2 kPa pure oxygen. Results show that the oxidation kinetics of the coarse grained PMFe-40Ni-15Cr…
ZnO Nanorods, Nanotubes and Nanorings: Controlled Synthesis and Structural Properties
Controlled synthesis of ZnO nanorods (ZNRDs), nanotubes (ZNTs) and nanorings (ZNRs) has been carried out by a two-step sonochemical/chemical process at room temperature without any catalyst, template or seed layer. The crystallinity, structure and morphology of ZNRDs, ZNRs and ZNTs were examined by X-ray diffraction (…
Processing Technique for Single-Walled Carbon Nanotube-Based Sensor Arrays
We investigated a selective assembly method of fabricating single-walled carbon nanotubes (SWCNTs) on a silicon-dioxide (SiO2) surface by using only a photolithographic process; then, we fabricated 8 x 8 field-emission transistor (FET) arrays for sensor applications. Photoresist (PR) patterns were made on a SiO2-grown…
Synthesis of 3R1and 1H Polytypes of Sulfate-Intercalated Layered Double Hydroxides (LDHs) by Postintracrystalline Oxidation and Simultaneous Intercalation-Oxidation of Thiosulfate
Well ordered 3R 1 polytypes of sulfate-intercalated Zn–Al and Zn–Cr LDHs could be synthesized at room temperature by intracrystalline oxidation of thiosulfate-intercalated LDHs by hydrogen peroxide. When the intercalation-oxidation sequence was slightly modified in such a way that the intercalation and oxidation of th…
Near-Infrared Emissions of Sm3+ in Li2O-K2O-BaO-PbO-Bi2O3-Ga2O3 Glasses
μNear-infrared (NIR) emissions have been observed in Sm3+doped low phonon energy heavy-metal-gallate glasses. The full-widths at half-maximum (FWHMs) of three fluorescence bands peaking at 960, 1038, and 1185 nm were derived to be 31, 36, and 42 nm, respectively, and the spontaneous transition probabilities were calcu…
Highly controllable ICP etching of GaAs based materials for grating fabrication
Highly controllable ICP etching of GaAs based materials with SiCl 4 /Ar plasma is investigated. A slow etching rate of 13 nm/min was achieved with RF1 D 10 W, RF2 D 20 W and a high ratio of Ar to SiCl 4 flow. First order gratings with 25 nm depth and 140 nm period were fabricated with the optimal parameters. AFM analy…
Synthesis and Characteristics of Conducting Polymer-Based Polypyrrole in Different Solvents
Polypyrrole (PPy) was synthesized under dry nitrogen atmosphere by chemical polymerization. The oxidant agent, ferric chloride, was mixed with several types of solvents, such as hydrochloric acid, deionized water, and acetonitrile, before the monomer pyrrole was added. The resultant precipitate was filtered and rinsed…
New Design of Channel Drop Filter by Triangular Photonic Crystal
We have designed a new type of optical channel drop filter (CDF) based on two dimensional triangular lattice photonic crystals. CDF operation is based on coupling to the photonic crystal waveguide. The proposed structure is optimized to work as a CDF. For obtaining the CDF characteristics and band structure of the fil…
Pressure effect on low‐temperature remanence of multidomain magnetite: Change in demagnetization temperature
We have conducted the first in‐situthermal demagnetization experiments on low‐temperature remanences of magnetite under high pressure up to 0.7 GPa, to investigate the pressure dependence of the demagnetization temperature (Td) defined as rapid decreases in the remanences. A sample of multidomain magnetite particles w…
