A sulfur family chemical cycle having ammonia as the working fluid and reagent was developed as a cost-effective and efficient hydrogen production technology based on a solar thermochemical water-splitting cycle. The sulfur ammonia (SA) cycle is a renewable and sustainable process that is unique in that it is an all-f…
Graphene is considered to be plasmon active only up to the infrared based on combined tight binding model and random phase approximation calculations. Here we show that the optical properties of graphene as measured by ellipsometry and simulated by density functional theory imply the existence of strongly localized gr…
The labels for Pd and Au in Fig. Also, the parameters for the Pd-Au cross-pair corresponding to the dotted curve in Fig.
This chapter contains basic concepts that can be used for all rotating machines and for power transformers. It presents a more complete analysis and more detailed circuit models of real-life transformers. When the transformer operates in sinusoidal steady state, the corresponding phasor circuit can be used to analyse…

This article explains the experimental results of ferroelectric polarization switching (FPS) of potassium nitrate ( $KNO_3$ ) with different polymers such as polyvinylidene fluoride (PVDF) and polyvinyl fluoride (PVF) using simple melt-press techniques. To analyze the ferroelectric polarization switching in potassium…
The effects of electric field frequency on the ac electrical treeing phenomena in an epoxy/reactive diluent/layered silicate (1.5 wt%) were carried out, in needle-plate electrode arrangement. A layered silicate was exfoliated in an epoxy base resin, by using our ac electric field apparatus. To measure the treeing prop…
The continuous phase volumetric overall mass transfer coefficient in a ceramic intalox saddle pulsed packed extraction column using axial dispersion model was studied for two different liquid-liquid systems containing water/acetone/toluene and water/acetone/n-butyl acetate. The effects of pulsation intensity, continuo…
The STATISTICA software package was developed by conducting a national research grant to facilitate the getting of cotton mixtures and their processing in a cotton spinning mill, ensuring effectiveness and efficiency in an important link of the textile supply chain. The objectives underlying the software package have…
Optically active polyacetylenes (LPA and DPA) and racemic polyacetylenes (RPA) were prepared by the polymerization of N-propioloyl-tyrosine methyl esters that derived from chiral and racemic tyrosine. All the polymers were characterized by Fourier transform infrared spectroscopy, 1H NMR, 13C NMR, gel permeation chroma…
The release of radioactive material due to accidents or terroristic actions can result in radioactive contamination of the environment and may lead to intake and incorporation of radionuclides with the consequence of prolonged radiation exposure. In this case, a decision about countermeasures must be carried out as so…
In order to improve the technology of cut strip casing, the factors influencing the casing effects of cut strips were examined by an orthogonal experiment in terms of tobacco throughput, cylinder rotating speed, nozzle pressure and hot air temperature, meantime, the regression models between the tested parameters and…
Li-excess layered Li[Li0.2Mn0.54Ni0.13Co0.13]O2 (LMNCO) nanoparticles are facilely synthesized using a surfactant-assisted dispersion method. We synthesize a novel core-shell structure cathode consisting of Li-excess LMNCO as core and Li-stoichiometric LiCoO2 as shell, and its electrochemical property is optimized by…
This paper deals with the design and implementation of series active power filter for the improvement of power quality. In power system there is a nonlinear load which seems to be the prime sources of harmonic distortion. A dissimilar type of load creates nonsinusoidal current from the mains, which give rise to harmon…
Exploration of yoctowell cavities on magnetic silica nanoparticles for encapsulation and controlled release of drug molecules has been performed by using naturally occurring stimuli, that is, pH. For more details see the Full Paper by S. V. Bhosale on page 5253 ff.
본 논문에서는 방사성 의약품의 자동합성장치에 사용되는 단채널 감마선 분광기를 보드 형태로 설계, 제작하고 그 특성을 측정 분석하였다. 감마선 검출을 위해 CZT (CdZnTe) spear 검출기를 이용하였고 아날로그 방식을 적용한 신호처리 보드의 형태로 감마선 분광기를 제작하였다. 측정을 위하여 방사성 물질인 Co-60을 시료로 사용하였으며, 최대 1173keV까지의 감마선 에너지 스펙트럼을 얻을 수 있었다. 아날로그 보드는 CZT spear 검출기에서 감마선을 검출하여 출력하는 신호를 적절히 변화시켜주기 위한 SF (shaping filter) 및 PHA (pea…
The Disposal of large quantity of plastic cover may cause pollution of land, water bodies and air. The proposed concrete which is made up by adding plastic in concrete may help to reuse the plastic cover as one of the constituent’s material of concrete, to improve the certain properties of concrete. The properties of…
Hard turning is a topic of great interest in today’s industrial production and scientific research. The hard turning technology has the potential for improving productivity against grinding in the manufacturing process. Today, tool manufacturers are constantly developing new combinations of coatings and substrates to…
Studies have been carried out to determine the natural radioactivity in construction sand and their associated radiation hazard in the old gold mining belt of Kakamega County, Kenya. The radioactivity concentrations of 226Ra, 232Th and 40K were measured using a gamma ray spectrometer with a NaI(Tl) detector. The resul…
Generally, steel fiber is broadly used to improve the mechanical and flexural strength properties of concrete, however, the steel fiber have some disadvantages including high density, fiber ball and corrosion etc. Recently, a new type of amorphous metallic fiber was developed to improve some properties of normal steel…
