Limosilactobacillus fermentum Lf2 (Lf2) and Bifidobacterium animalis INL1 (INL1) are two autochthonous probiotic strains that produce exopolysaccharides (EPS), and some of these molecules were associated with health-prom...

A new numerical model to describe the microstructural evolution of a eutectic nodular cast iron during its cooling is presented. In particular, equiaxial solidification assuming an independent nucleation of austenite and...

A pressing issue in materials science is the controlled application of ceramic composite materials at high temperatures in modern technologies, particularly in nuclear physics, atomic energy, aerospace, and rocket engine...

Lean duplex stainless steels (LDSS) emerged as a competitive duplex stainless steels (DSS) where Ni is partially replaced by lower cost alloying elements such as Mn and N. However, to date there has been little to no inf...

The excellent mechanical properties, high thermal conductivity and corrosion resistance combined with moderate cost make superferritic stainless steels (SFSS) commercially attractive. Though these steels are finding incr...

Abstract Aiming at the problems of easy settlement and insufficient durability of traditional materials under special backfilling conditions in the northwest loess area, this study prepared controllable low-strength read...

Through numerical simulation based on the particle flow method, DEM numerical test samples are generated in accordance with the results of laboratory tests on standard sand. Using gravity deposition modelling of irregula...

By the method of microarc oxidation for different types of electrolytes (which include KOH, Na2SiO3, Н2О2, NaOH, NaAlO2, Na5P3O10, NaF) and electrolysis conditions, multifunctional ceramic coatings on a magnesium alloy...

In the article, the characterization of the morphology, chemical composition, and elemental distribution in the Ti-based carboboride M(C,B) in (wt.%) Fe-0.72C-2.75B-5.05W-5.57Mo-10.35Cr-2.60Ti multi-component alloy is fu...

The classical micropolar constitutive theory is reformulated within the framework of the microplane concept in order to obtain constitutive equations and models including available and, hopefully, more precise informatio...

Abstract Non-penetration laser welding of lap joints in austenitic stainless steel sheets is commonly preferred in fields where the surface quality is of utmost importance. However, the application of non-penetration wel...

Residues discarded at cherry fruit harvesting were extracted with ethanol from ‘Chelan’, ‘Brooks’ and ‘Sunburst’ varieties to obtain cherry fibers constituted by the cell wall polysaccharides, applicable as f...

Ultracompact chip-integrated all-optical diode is realized experimentally in a plasmonic microstructure, consisting of a plasmonic waveguide side-coupled two asymmetric plasmonic composite nanocavities covered with a mul...

Composite films based on chitosan, glycerol and magnetic iron oxides were obtained by two different procedures: in situ generation of iron oxide particles in the already formed films and dispersion of previously synthesi...

Abstract The demand for healthy ingredients in food products including ice cream, is continuously increasing. The potential of a combination of milk polar lipids (MPL) and casein hydrolysate (CH) to replace synthetic emu...

The corrosion behavior of two wrought super duplex stainless steels (SDSS), UNS S32750 and UNS S32760, and a cast duplex stainless steel (DSS), DIN/EN 1.4517, was evaluated in 3.5 wt% NaCl and ASTM D1141 synthetic seaw...

Abstract Alkali-activated materials (AAMs) are promising for rapid concrete repair but are hindered by excessive drying shrinkage. This study evaluates the efficacy of MgO-based (MEA), CaO-based (CSEA), and calcium sulfo...

Abstract Current research on the fabrication of rolled composite plates primarily focuses on processing and bonding mechanisms. Compared with hot-rolling technology, the electrically assisted rolling process has demonstr...

For the X80 pipeline steel, electrochemical impedance spectroscopy and potentiodynamic polarization curves were employed to examine the electrochemical corrosion behaviors of its base metal and weld joint under varying t...

The inadequate corrosion resistance and conductivity of metal bipolar plates are major obstacles to the commercialization of proton exchange membrane water electrolysis (PEMWE). In this work, Nb/NbN/Mo-containing NbN mul...
