Primary recrystallised sheets of 3% silicon steel from two different industrial processing routes have been examined after laboratory annealing to initiate secondary recrystallisation. Metallography included etching to reveal individual dislocations and sub-boundaries as well as EBSD in scanning electron microscopy. R…
We present a manipulation technique of cells and cell spheroids by utilizing cell-size collagen hydrogel microbeads. Collagen hydrogel beads were prepared by using non-equilibrium microfluidic W/O droplets containing hydrogel molecules, formed in a continuous phase of a water-soluble organic solvent. Monodisperse coll…
The structure and microhardness of a nanocomposite nickel galvanochemical coating formed with Watts electrolyte and containing 60 mg/dm 3 carbon nanotubes are studied. An addition of carbon nanotubes to the electrolyte leads to a substantial modification of the morphology and texture of grains, grain refinement, and a…
In this paper, we showed the realization and the characterization of a PZT-actuated micro-cantilever. The measurement and the modeling of its resonant frequency allow deducing the cantilever length. Using this value and combining the measurement and the modeling of the cantilever displacement amplitude at a given volt…
Austenitic stainless steels of the AISI 304 and 316 grades, amongst over other hundred compositions of stainless steels available in the market, are the most frequently used ones worldwide. They are selected for numerous applications due to their favorable combination of characteristics such as low price, moderate to…
Using a combination of first-principles calculations and Monte Carlo simulations, we show that Fe-containing silicates such as olivines naturally offer a way for visualizing tracks left by diffusing vacancies. Fe in its 2+ and 3+ valency states prefers two distinct cation sites in the olivine structure. Vacancies form…
Lminescent glass is widely used in building, energy saving, emergency lighting and art crafts; The energy consumption for global illumination is rising year by year, and the energy consumption has become a global problem; the research of luminescent glass is important for the developing of the energy-saving light. In…
t has been demonstrated in previous work that a two-step annealing treatment, including a low-temperature, long-time annealing and a subsequent high-temperature annealing, is a promising route to control the microstructure of a heavily deformed metal. In the present study, structural parameters are quantified such as…
The dynamic process of grain evolution in a Super304H austenitic stainless steel was studied in compression tests. The tests were carried out to a strain of 0.7 at temperatures ranging from 700 to 1000°C and strain rate of 10-3s-1. In addition to single pass compression the multiple compressions with changing the load…
A remediation technique of cracked concrete by bacterial mediated carbronate deposition i.e. bio-deposition is discussed. Bio-deposition is a technique that comes from a broader category of biomineralization. The aim of this study was to investigate the plugging of artificially cracked concrete using bacteria Sporosar…
The microstructure evolution in commercial AlMgSi alloys during and after extrusion of a simple U-shaped profile has been modelled. The strain, strain rate and temperature along a set of particle paths are taken from FE-HyperXtrude simulations and used as input to the work hardening model ALFLOW, to predict the evolut…
Water-soluble Sb 2 S 3 sub-microspheres were synthesized by aqueous-phase arrested precipitation using mercaptoacetic acid as capping agent and thioacetamide (TAA) as sulfur source. The effects of the experimental conditions, such as temperature, sulfur source, reactants concentration and reaction time, on the shapes,…
Carbon nitride (CN( x )) and diamond-like carbon (DLC) coatings were prepared by dc magnetron sputtering at room temperature. Different partial pressures of N(2) were used to synthesize CN( x ) to evaluate the relationship between the atomic percentage of nitrogen and hemocompatibility. Auger electron spectroscopy and…
The impulse behavior of composite short rod-plane air gaps with a dielectric-covered rod under positive lightning and switching impulse voltages is investigated, by monitoring the electric field strength at the earthed plane, by still photographs of corona discharges and through electric field computations. Experiment…
Reduced activation ferritic-martensitic steels are considered for future applications in fusion power plants. The thermal stability of two steels (ODS-Eurofer and Eurofer-97) was evaluated in cold-rolled samples annealed below 800°C. These grades have similar chemical compositions except for the presence of nanosized…
The helix is a critical conformation exhibited by biological macromolecules and plays a key role in fundamental biological processes. Biological helical polymers exist in a single helical sense arising from the chiral effect of their primary units-for example, DNA and proteins adopt predominantly a right-handed helix…
This technical paper investigates the electrical properties of the Zinc doped SnO2(Zn-doped SnO2) nanostructures that have been prepared by the immersion method by different period of immersion process. The experiment was conducted in 3 different time constraint. The thin films were characterized by using current-volt…
Electrodeposition of the Sn-In alloy from a sulfate electrolyte in the presence of synthanol, formalin, and butynediol-1,4 was studied. An electrolyte composition and conditions for obtaining an alloy of prescribed composition are suggested.
The aim of this study was to investigate whether L-Ascorbic acid would facilitate the anti-obesity effects of chitosan and psyllium husk in vivo. The study was carried out with male Hartley guinea pigs for 5 weeks. The results show that chitosan itself did not influence body weight gain and food efficiency ratio (FER)…
Recent observations show that the strain reversal affects significantly and in a complex way both the static recrystallisation (SRX) and strain-induced precipitation (PPT) kinetics in Nb-microalloyed steel. It is already known that the recrystallisation stagnation is a consequence of the competition between the drivin…
