The research was conducted for castings with 3-25-mm wall thicknesses and using AlTi5B1 master alloy as well as AlTi75 additions. A thermal analysis was performed to determine the real cooling rate and the degree of undercooling (ΔT α = T α − T min, where T α—the equilibrium solidification temperature, T min—the minim…
This study is designed to analyze the similarity of fit and appearance between 3D virtual torso length sloper with real torso length sloper according to three 3D virtual clothing simulation programs (Optitex, CLO 3D, i-Designer), three body types (A, N, H) and fit status. We selected three representative body type mod…
Nanoparticles are key components in the advancement of future energy technologies; thus, strategies for preparing nanoparticles in large volume by techniques that are cost-effective are required. In the substitution of fossil-fuels by renewable energy resources, nanometersized particles play a key role for synthesizin…
By chemical spray pyrolysis method. The CdO thin film prepared at constant film thickness (350 nm). The prepared films are annealed at a temperature of 450 and 500 °C. The optical properties are calculated from the measurement of UV-Visible spectrophotometer spectrum in the range of (300-900) nm at room temperature. T…
The processes of high-energy milling and gained importance among the unconventional methods. In this work, we seek to compare the power supply two types of high energy mills (vibratory mill (SPEX) and planetary mill) with the variation of the milling power. The millings were carried out with a mixture of chromium oxid…
Cd-Pb thin films were electrodeposited from a diluted chloride solution using stainless steel rotating disc electrode. The linear sweep voltammograms of the single metallic ions show that electrodeposition of these ions was mass transfer control due to the plateau observed for different rotations at concentration (50…
Sealed radioactive sources are used in a wide variety of occupational settings and under differing regulatory/licensing structures. The definition of a sealed radioactive source varies between U.S. regulatory authorities and standard-setting organizations. Potential problems with sealed sources cover a range of risks…
Nanostructured CdSnO3 thin films were prepared by spray pyrolysis technique. The nanostructured CdSnO3 film showed selectivity for LPG gas over other conventional gases. The maximum LPG response of 1460 for the sample S2 at 350 °C was achieved. The quick response (TResponse = 5 s) and fast recovery (TRecovery = 11 s)…
In this study, different compositions based on rice husk carbon and kaolinitic clay aimed at obtaining ceramic filter were studied. Three compositions of 40, 60 and 80% rice husk of the total mass were prepared. The specimens were uniaxially compressed in rectangular shape at pressure of 28 MPa and were sintered at te…
Powder Metallurgy (PM) Techniques consists in a suitable technique to process composites materials. A specific PM technique of mechanical alloying developed to produce new materials in the solid state is a well known route to obtain aluminum alloys metal matrix composites. Aluminum alloys metal matrix composites allie…
DIFFERENT POLYURETHANE (PU) elastomerics formulations were prepared by using 4, 4'-diphenyl methane diisocyanate, polyol (castor oil; CO), chain extender (1,4-butanediol); CE and catalyst. The prepared PU formulations were applied as coating films up on the cotton/ polyester blend fabric surface. The specimens were cu…
The end of the 19 th century brought about a change in the dynamics of computing by the development of the microprocessor. Huge bedroom size computers began being replaced by portable, smaller sized desktops. Today the world is dominated by silicon, which has circumscribed chip development for computers through microp…
A computer simulation has been developed to estimate the transient temperature and pressure distributions in a high-temperature superconducting (HTS) power cable cooled by a forced flow of subcooled LN2. This simulation is critical for assessing the effects of short-circuit accidents in practical HTS power cables. Whe…
In a search for a simple proximity system of a topological insulator and a superconductor for studying the role of surface versus bulk effects by gating, we report here on a first step toward this goal, namely the choice of such a system and its characterization. We chose to work with thin film bilayers of grainy 5 nm…
We designed an ultra-high frequency (UHF: 300MHz to 3 GHz) ferrite circulator to investigate magnetic parameters, which are suitable for a self-biased GHz circulator design. The size of the ferrite disk was 1.58 mm in thickness and 13.5 mm in diameter. The saturation magnetization ( $4{\pi}M_s$ ) of 3900 Gauss, intern…
Hierarchical nanostructures of single phase γ-TaON flowers have been successfully synthesized using a simple wet-chemical route in addition to subsequent thermal nitridation. These flower-like particles exhibit an obvious improvement in visible-light-driven photocatalytic activity.
ABSTRACT The evolution of the morphology of an acrylic/CeO2 hybrid latex synthesized by a two step seeded semibatch emulsion polymerization process was investigated. The seed was produced by batch miniemulsion polymerization and in the second step a neat monomer preemulsion was fed to the seed to increase the solids c…
Zirconia was prepared at low temperatures (<450°C) using single several source precursors based on zirconium carboxylates where the R groups were systematically varied. The combination of density functional theory (DFT) calculations and extensive characterization of the precursors (i.e., X-ray diffraction, thermal gra…
The Hemidesmus indicus is used to cure leprosy, leucoderma, itching, skin disease, asthma, bronchitis, leucorrhoea, dysentery, piles, syphilis, and paralysis. The present study was aimed to investigate the phytochemical and antibacterial activity of Hemidesmus indicus root. The root extracts of Hemidesmus indicus were…
Molecular tunnels in enzyme systems possess variable architecture and are therefore difficult to predict. In this work, we design and apply an algorithm to resolve the pathway followed by ammonia using the bifunctional enzyme formylglycinamide ribonucleotide amidotransferase (FGAR-AT) as a model system. Though its cry…
