Detecting Partial Discharge (PD) in Gas Insulated Switchgears (GIS) is the most effective method to assess the insulation condition. One of the popular method PD detection is Ultra-High-Frequency method (UHF-method). UHF antenna/sensors are the most important part of UHF method PD measurement. The sensor should be sim…
In the article the results of domestic development and application of aluminum alloys in the form of a rolled, extruded and forged semi-finished products as X-ray contrast materials, conductors, resistant to high temperatures, and structural materials of different destination.
Solid-fuel stoves are used in developing countries, remote locations, and in general more commonly due to convenient fuel cost. The possibility of using the stove heat to heat water and produce electricity represents an added benefit. This work presents an application of thermoelectric generators to a solid-fuel stove…
The demand for renewably sourced biodegradable materials has increased the need to produce materials that combine appropriate functional properties at competitive costs. Thermoplastic starch and polyester blends are an interesting alternative to current materials due to the low cost of starch and the functional proper…
Article Preparation of individualised lignocellulose microfibrils based on thermomechanical pulp and their effect on paper properties was published on August 1, 2015 in the journal Nordic Pulp & Paper Research Journal (volume 30, issue 3).
The purpose of this work is to search reduced graphene oxide (RGO) phase by identifying the molecular bonding, energy band gap and phase of old coconut shell. The characterization was performed by using FTIR, Uv-Vis and XRD spectroscopy. The heating temperature used in this work was 400°C and 600°C. Furthermore, the t…
This paper presents a novel Partial Discharge (PD) localisation method, based on PD pulse Rise-Time and Transfer Function (RTTF), for use in on-line cable PD monitoring systems. This is based on the change in rise time as a function of cable length along which a PD pulse has propagated. A comparison with four other we…
In order to avoid the inherent photo-catalysis and aggregation of TiO2 in PPS, TiO2 nanoparticles were coated with SiO2 layers, which were chosen as the UV absorbent to improve the UV stability of polyphenylene sulfide (PPS) fiber. The PPS–TiO2@SiO2 nanocomposites fibers were prepared via melt spinning, and the nanoco…
Abstract Clay-based nanostructures were prepared from kaolinites of varying structural order by two different methods. In the first method the kaolinite-urea precursor, obtained by dry grinding, was intercalated further with triethanolamine and the tetraalkylammonium salt was synthesized in the interlamellar space. Ex…
Indium oxide (In 2 O 3 ) thin films are successfully deposited on glass substrate at different deposition times by an ultrasonic spray technique using Indium chloride as the precursor solution; the physical properties of these films are characterized by XRD, SEM, and UV-visible. XRD analysis showed that the films are…
Summary This research was studied on the cure characteristics and mechanical properties of rubber compounds using vegetable oil as the processing aid in styrene butadiene rubber compound such as castor oil and jatropha oil in comparison with petroleum based aromatic oil. The quantities of the oils varied from 0 to 9 p…
Cross-linked polyethylene (XLPE) may be operated under repetitive pulse voltage and low temperature environment. In recent years, many influencing factors to the treeing process, which is a main reason for the aging of XLPE have been researched. However, the tree behavior under repetitive pulse voltage and low tempera…
Thanks to its excellent insulation and cutoff performances, SF6gas has been applied to power equipment since the 1960s and is now widely used for several kV to 1,000 kV-class GIS, GCB, and GIL. However, since 1997, when SF6was designated at COP3as a greenhouse gas to be reduced, there has been a wish to use an alterna…
AIM: In vivo imaging using (19)F MRI is advantageous, due to its ability to quantify cell numbers, but is limited for a lack of suitable labels. Here, we formulate two stable and clinically applicable labels for tracking two populations of primary human dendritic cells (DCs) simultaneously. MATERIALS & METHODS: Plasma…
Octahedral Co3O4 nanoparticles were synthesised in an aqueous ammonia solution using hexagonal β-Co(OH)2 nanoplates as starting materials. Electron microscopy analysis indicates that the Co3O4 particles have diameters of 20-40 nm and adopt a well-crystallized cubic spinel structure. The octahedral habit was verified b…
Abstract Organoclays are sorbent materials prepared from clays by exchanging inorganic with organic cations. Their properties depend on the loading and conformational structure of the organic cations, but little information is available about the surface structures of organoclays. In this work, X-ray photoelectron spe…
Polymeric nanomaterials have extensively been applied for the preparation of targeted and controlled release drug/gene delivery systems. However, problems involved in the formulation of synthetic polymers such as using of the toxic solvents and surfactants have limited their desirable applications. In this regard, nat…
The diatom succession and sedimentation during 2011 in a subtropical, deep alpine lake (Lugu Hu, Southwest China) were studied. The seasonal patterns in diatom assemblages were related to light, nutrient availability, and thermal regime. Peaks in the concentration of the planktonic diatoms (Asterionella formosa and Cy…
BACKGROUND: Microbial polyesters, also known as polyhydroxyalkanoates (PHAs), closely resemble physical and mechanical features of petroleum derived plastics. Recombinant Escherichia coli strains are being used in industrial production of PHAs in Stirred Tank Bioreactors (STRs). However, use of Air-Lift Reactors (ALRs…
Extensive first-principles calculations suggest that inverse Heusler compounds , , , and are the candidates to achieve fully compensated ferrimagnetic spin gapless semiconductors. It is shown that only the holes can be 100% spin polarized in , while both the excited electrons and the holes around the Fermi level 100%…
