Abstract Microplates are vastly used in MEMS and NEMS devices. Due to size effect, classical theories of continuum mechanics can not be used to model mechanical behaviour of them. Instead, higher order continuum theories should be implemented. Modified Strain Gradient Theory (MSGT) is considered to be one of the most…
The formation of ncl-Si in the amorphous matrix a-SiOx:H using a time-modulated DC plasma at an elevated oxygen content of $${{C}_{{{{{\text{O}}}_{2}}}}}$$ = 21.5 mol % in a gas mixture of (SiH4–Ar–O2) is investigated. Plasma modulation implies the repeated (n = 180) switching on (for ton = 5, 10, 15 s) and switching…
We investigated the structural, electronic, magnetic, and phonon properties of ${\mathrm{Pu}}_{3}M$, where $M$ = Al, Ga, In, and Tl, using first-principles calculations with the spin-orbit coupling taken into consideration. All four compounds are found to contain transverse phonons along [011] and [111] that remarkabl…
Natural fibers are an alternative to man-made fibers for the manufacturing of preforms intended for composite applications. Some of the textile manufacturing processes, such as spinning technology, are not suitable for the production of optimized preforms for composite materials. Those preforms are made of yarns, whos…
In article number 1905923, Xiaosheng Fang and co-workers fabricate nickel-coated silver nanowires to form a transparent electrode with an enhanced work function value, which supports a transparent Schottky photodiode combining UV filtering and bias-free photodetection to short-wavelength blue light. This work proposes…
New Ni(II) and Pd(II) complexes (Ia and Ib) are synthesized on the basis of the azomethine compound 2-[(E)-[4-methyl-2-[(Z)-p-tolylazo]phenyl]iminomethyl]phenol. The structures and properties of the complexes are characterized by IR spectroscopy, 1Н NMR spectroscopy, and X-ray diffraction analysis (СIF files CCDC nos.…
Abstract The subject of this study was the diatom taphocoenoses preserved in the surface sediments of the northern part of Puck Bay, southern Baltic Sea. Three subbotom sedimentary cores ZP1/0518, ZP2/0518 and ZP3/0414 collected in the vicinity of the Hel Peninsula from a water depth of 65 m, 47 m and 50.2 m, respecti…
Abstract The effect of heat treatment on microstructure and mechanical properties of SiC/Mg-Al-Sr alloy matrix composite was investigated. The heat treatment involved annealing at 425, 375, and 325°C for 4 hours, water quenching then ageing at room temperature for 48 hours. The heat treatment process caused dissolutio…
Abstract Attenuated total reflection infrared spectroscopy is used to determine the free charge carrier concentration in arrays of silicon nanowires with characteristic transverse sizes of 50–100 nm and a length of the order of 10 μm formed on lightly doped crystalline p-type silicon by metal-assisted chemical etching…
Abstract For decoration purposes, aluminum metal has widely used metal coloring techniques to enhance the aesthetic value of the metal. Most coloring techniques of the aluminum metal use aluminum metal dipping with dye or with chrome (Cr) directly. This coating technique has the disadvantage, such as the color fade ea…
Inhomogeneous small-amplitude plane waves of (complex) frequency ω are propagated through a linear dissipative material which displays hereditary viscoelasticity. The energy density, energy flux and dissipation are quadratic in the small quantities, namely, the displacement gradient, velocity and velocity gradient, ea…
Abstract This contribution deals with the formation and decomposition of Widmanstätten austenite during solidification of the thin belt-casted strips made of a grain oriented electrical steel (GOES). Solidification of liquid steel started with the formation of δ-ferrite. Cooling in the δ + γ phase field resulted in th…
Abstract Cellulose is a biopolymer whose availability is abundant in nature. In its development, cellulose is widely used in the form of nanocrystalline cellulose because it has better properties than the original material. The method commonly used to produce nanocrystalline cellulose is acid hydrolysis. In this study…
Abstract Properties of carbon black (CB)-filled styrene-butadiene rubber (SBR) vulcanizates include rheometric, mechanical and morphological in presence of alkanolamide were studied. The synthetic rubber was filled by CB at a settled loading at thirty parts per hundred rubber (phr). The alkanolamide was derived from e…
Abstract The morphology of CdS nanocrystal arrays self-assembled during the evaporation of a behenic-acid organic matrix on a wetted substrate surface is studied by atomic force microscopy. The dependence of the morphology of nanocrystal arrays on the initial matrix surface is studied. The morphology of nanocrystal ar…
Abstract We report on the synthesis of Fe3O4/TiO2/BiOCl nanocomposites using Sargassum crassifolium extract as magnetic nanophotocatalyst for cadmium sequestration. Utilization of nanotechnology via surface engineering and functionalization has been considered for heavy metals sequestration. In this work, we are going…
Abstract This experimental research aimed to determine the most acceptableBatuan (Garciniabinucao) Fruit Preservation.Specifically, it sought to answer if there is no significant difference in the acceptability of Batuan Fruits Preserved using different methods of preservation as to appearance, aroma, taste, texture a…
To identify the impeller types automatically for an overhead stirrer operation, a digitalization of the analog magnetic signal of the permanent magnet arrays was performed. The permanent magnets were installed into the impeller shaft in NS-SN array, and their magnetic fields were measured by a hall sensor while the im…
Systematic theoretical calculations are performed to investigate the dopant effect of Fe on stability, electronic and magnetic properties of the newly synthesized all-boron fullerene B40. The results reveal that as a typical ferromagnetic element, Fe atoms can either be chemically externally adsorbed on, or internally…
Point contact Andreev reflection studies have been conducted on FeSe single crystals by lowering the temperatures down to 0.5 K. The point contact Andreev reflection spectra were analyzed in the framework of the two-band model. As a result, the presence of two anisotropic superconducting gaps in FeSe were certainly es…
