Ethylene propylene diene monomer rubber (EPDM) is an excellent rubber for outdoor use. Silicone rubber (SiR) containing EPDM may show improved weathering resistance. Hence, EPDM is blended with silicone rubber with various blend ratios. After processing and curing, the electrical and mechanical properties of the SiR/EPDM blends are determined. The heat and weathering resistance of the SiR/EPDM blends...
A possible synthesis mechanism of magnetic nanoparticles nickel, prepared by chemical reduction with hydrazine hydrate in ethylene glycol was obtaind. On this basis, different modifiers were used to improve the surface condition of magnetic nanoparticals, resulting to the good dispersion and stability of magnetic nanoparticles and with being more easily outer coated. Then the shell material CdTe was...
The effect of gamma-ray irradiation on relative permittivity, ac conductivity and dielectric loss tangent of epoxy resin and polyethylene has been investigated. Laminated samples were irradiated by 60Co gamma source at room temperature in air with a dose rate of 10 kGy/h and the total dose were 100 kGy and 1000 kGy. The dielectric properties were measured by using a Precision LCR Meter (Agilent E4980A)...
To support development processes for nanodevices, we want to utilize the information related to experiments from nanodevice development research papers. In this paper, we propose a new guideline for constructing a tagged corpus of nanodevice development papers to achieve this goal. We also propose the use of a corpus construction support tool. To speed up the construction process, we propose an approach...
Novel blue light-emitting materials were designed by the substitution at the 4-position of 1,8-naphthalimide with electron-donating phenoxy group. The effect of molecular structure on the photophysical, electronic structure properties of the derivatives was explored by UV-visible absorption spectroscopy, photoluminescence spectroscopy, cyclic voltammetry and quantum chemical calculations. Both UV-visible...
Different size SnS quantum dots are prepared by chemical bath deposition. size of the particles are varied from 2.4 to 14.4 nm by varying the deposition time from 30 to 120 min. solar cells are fabricated with these quantum dots. Cu2S coated FTO is used as counter electrode instead of the conventional platinum electrode and Na2S as electrolyte. Cu2S acts as a good catalyst for the polysulfide electrolyte...
Adsorption of Remazol Brilliant Blue R (RBBR) by rambutan peel (RP) was examined. The adsorption experiments were carried out under different conditions of initial concentration (25–500 mg/L), solution pH 2–12 and RP dose (0.05–1.2 g). The influence of these parameters on the adsorption capacity was studied using the batch process. RBBR adsorption uptake was found to increase with increase in initial...
The e-carboline compound and evodiamine were synthesized with improved Bischler-Napieralski-type and Diels-Alder-type reactions by taking tryptamine and N-methyl anthranilic acid as starting materials, enjoying the characteristics of few steps, simple ness, mild reaction conditions, high productivity and less pollution etc. Conduct elementary analyses on the resulting compounds and characterize them...
The effect of different mixed fertilizers on the growth and development in Stevia Rebaudiana Bertoni had been studied in the open field. The results showed that the growth rate, plant height, stem thickness, leaf areas and dry matter weight using organic cultivation were less than that of using the chemical fertilizers in the early stage after transplanting. But 60 days after transplanting, there...
In this paper, near-infrared spectroscopy (NIRS) combined with discriminant analysis was used as a qualitative tool to distinguish Fructus forsythiae from different geographical origins by collecting and analysing the NIR spectra in the range of 12000-4000cm-1. NIR spectra were analyzed by two methods: clustering analysis and discriminant analysis. In the former, the second derivative and Norris smoothing...
This paper expounds the importance of saving energy of ironmaking system in iron &steel industry, as well as the meaning of exergy analysis. Black box models of exergy analysis are established for pelletizing, sintering, coking and blast furnace process in ironmaking system, and the exergy efficiency and exergy loss are calculated. It reveals the exergy loss types and quantity as well as the effect...
We developed a computer graphics teaching material (QT movie) in a tablet computer (iPad), which shows rearrangement of a diatomic molecule and an atom by collision. The teaching material provides information concerning changes of potential energy and realistic image of intermediate in I + H2 ? HI + H, which leads to better understanding of reaction profile. Practice of the teaching material to the...
This paper presents XPS depth profiling study on the materials used in amorphous indium-gallium-zinc oxide thin-film transistors (a-IGZO TFTs) having Ti and Mo source/drain (S/D) electrodes. The XPS results suggest that there are some differences between Ti/a-IGZO and Mo/a-IGZO interface regions for the chemical states of the materials. The chemical states of the back-channel surfaces are also found...
Philips has asked its suppliers to declare their compliance with REACH, ROHS and other requirements by making BOMcheck declarations, with a preference for Full Material Declarations. The roll out started in March 2010 and more than 1200 Philips suppliers have started to make declarations, mainly regulatory compliance declarations. There are a number of hurdles to overcome such as awareness raising,...
A generic model is a model that is built for a class of system and can be implemented for a specific system through changes in input data alone, without any structural changes to the model. In this paper, we propose a framework for building such generic model for non-steady state process networks, which are characterized by flow of materials between interconnected nodes. The framework comprises two...
This work presents the physico-chemical behavior of several enameled copper wires systems such as PolyEsterImide (PEI)/PolyAmideImide (PAI) or PAI based multi layers compared to PolyImide (PI) which remains the basic enamel material for high temperature applications. The structural, thermal and electrical properties of these systems have been investigated before and after aging in the 200°C–400°C...
A flat microwave absorber working at frequency 1.8GHz was developed by impregnation of activated carbon and polyurethane. The activated carbon is prepared from the conversion of rubber wood sawdust through chemical activation process using ZnCl2 solution as the precursor agent. The process involves leaching, heating and washing. The impregnation ratio between ZnCl2 and rubber wood sawdust were at...
Adsorption of Reactive Black 5 (RB5) and Reactive Orange 16 (RO16) from their binary mixture using MgA-NO3 -layered double hydroxide (MgAlNO3-LDH) was conducted in a batch system. First order derivative spectrophotometric method was used for simultaneous analysis of RB5 and RO16 in binary mixtures. The effect of pH, contact time, and initial concentration were investigated. The results of these analyses...
This paper describes two different types of bipolar plates and four different types of flow topologies for a regenerative fuel cell. A three-cell graphite bipolar plate with three continuous serpentine channels was constructed to determine the Current vs. Voltage and the H2 Produced vs. Voltage graphs. Experimental results are shown for a three-cell Regenerative Fuel Cell.
In this paper, the effect of AC Corona on the hydrophobicity of room temperature vulcanizing (RTV) silicone rubber materials is studied with a pin-plate electrode corona accelerate aging model.
