Forming limit curve (FLC) is a suitable method for determining the metallic sheets formability. The purpose of the present research is to expose a simulation-based approach to predict the FLC in two-layer metallic sheets. In this paper, the formability of two-layer (AA3004-ST12) metallic sheets, with an aluminum inner…
The preparation technology for an Al–2% Sc–0.5% Y master alloy using aluminum–manganese alloys has been developed and tested. The microstructure of the prepared master alloy is studied and the compositions of intermetallics is determined. The efficient technological parameters of the synthesis are determined. It is sh…
Graphene, thanks to its ability to support Surface Plasmon Polariton (SPP) waves in the Terahertz (THz) band (0.1- 10 THz), enables the miniaturization and electrical tunability of miniature antennas suited for wireless communication among nanosystems. Despite graphene antennas have been extensively analyzed by means…
Haynes 25 alloy (also known as L-605 alloy) is cobalt based super alloy which has widely applications such as aerospace industry, turbine and furnace parts, power generators and heat exchangers and petroleum refining components due to its excellent characteristics. However, the workability of this alloy is more diffic…
Graphene materials obtained by different synthetic routes possess dissimilar amount of defects and surface functionalities, which can influence their electrochemical performance towards the detection of electroactive probes. Oxygen-containing groups can be either detrimental to the heterogeneous charge transfer or pro…
Majority of non-Foster-based metamaterials or antenna matching circuits are based on simple networks that contain parallel or series combination of positive and negative capacitor. It is well-known that these networks are stable, if the overall capacitance is positive. It is shown that this stability criterion becomes…
Recent analytical and numerical work on field-driven domain wall propagation in nanowires and thin films has shown that for large transverse anisotropy and sufficiently large applied fields the Walker profile becomes unstable before the breakdown field, giving way to a domain wall whose speed increases at a slower rat…
The Callovian-Oxfordian (COx) clay formation in the Paris Basin (France) has been the target of many studies investigating the feasibility of deep nuclear waste disposal in a reduced clay formation. To determine the mobility of radionuclides in the host rock formation, modeling of the porewater chemistry, particularly…
Magnetization dynamics in a three-layered nanopillar Co/Cu/Co structure with one fixed and one free layer driven by external magnetic field and spin-polarized electric current was investigated using methods of the theory of bifurcations. Mathematical model is based on the Landau-Lifshits-Gilbert equation with the curr…
BACKGROUND: Determination of cell-associated antiretroviral drug concentrations is necessary for research into reservoirs of HIV. Variation exists in cell-associated drug concentrations among research groups. One cause for this may be washing cells during processing. We explored spinning cells through oil to minimize…
In this study, a multilayer iridium coating was processed on niobium substrate by double glow plasma technology. The coating was ablated under an oxyacetylene flame at a temperature up to 2000°C. The oxidation behavior and the failure mechanism of the ablated coating were investigated. The surface and fracture surface…
Bioassay-guided fractionation of the root of Machilus obovatifolia led to the isolation of four new lignans, epihenricine B (1), threo-(7'R,8'R) and threo-(7'S,8'S)-methylmachilusol D (2 and 3), and isofragransol A (4), along with 23 known compounds. The compounds were obtained as isomeric mixtures (i.e., 2/3 and 4/20…
Using nanoscale electrical-discharge-induced rapid Joule heating, we developed a method for ultrafast shape change and joining of small-volume materials. Shape change is dominated by surface-tension-driven convection in the transient liquid melt, giving an extremely high strain rate of ~10 6 s –1 . In addition, the he…
Syntactic foam composites are widely used as aviation, construction and marine materials because of their high specific strength, specific modulus, damage tolerance and low moisture absorption. The present work aimed to investigate the compression behaviours of syntactic foam reinforced by warp knitted spacer fabric (…
Electron-beam-induced current (EBIC) measurements have been employed for the investigation of the local electrical properties existing at various types of electrical junctions during the past decades. In the standard configuration, the device under investigation is analyzed under short-circuit conditions. Further insi…
A series of NiO modified Co3O4 composites were synthesized by the citrate method. The optimal composite is of the Co/Ni atomic ratio of 9:1. The maximum power density achieved by zinc-air battery using this composite is 100.1 mW cm-2 at the current density of 148.3 mA cm-2. The zinc-air batteries have discharge capaci…
PURPOSE: A biochemical approach to implant surfaces can improve bone growth, resulting in desirable bone-implant interfaces. This study was conducted to identify the effect on osseointegration of direct coating of titanium (Ti) implants with poly(D,L-lactide-co-glycolide)(PLGA)/recombinant human bone morphogenetic 2 (…
In this article, conductive inks for inkjet printing with high content of silver nanoparticles with the addition of organic silver salt and polymer additives are developed and investigated. Silver nanoparticles are shown to be stably dispersed in a solvent and the presence of a silver salt and a polymeric surfactant e…
BACKGROUND: In 2005, the L'Oréal Institute for hair and skin research carried out a multiethnic study to investigate hair breakage in women residing in the U.S.A. In this study it was reported that a large percentage (96%) of the African-American respondents experience breakage. A combination of structural differences…
The effect of acetate ions on the corrosion of reinforcing steel in chloride environments have been investigated. For this purpose, potentiodynamic polarization curves, electrochemical impedance spectroscopy (EIS) and compressive strength techniques were used. In the presence of acetate ions polarization resistance (R…
