Currently, there is no standardised method for making nanomaterials or evaluating their toxicity. Studies show great variability and lack of reproducibility in results, with the discrepancies being caused due to assays used to evaluate exposure toxicity. While the traditional biochemical methods for evaluating toxicit…

This paper proposes a method of designing EM absorber panels under oblique incident waves. TM and TE wave reflection characteristics of the absorber panel show its anisotropy under oblique incidence. By using the wire array sheet proposed this paper, TM and TE reflection coefficients in oblique incidence can be matche…
In this study, we electroplate Cu electrode on Si substrate to realize a large-area vacuum nanogap for electron tunneling.We used cathode coating, cathode rotation, asymmetric current regime, and electrolyte temperature stabilization to obtain the regular geometry of the Cu electrode and reduce its internal tension.Su…
This work presents the results of experimental study of deformation and destruction of a new generation of structural materials − ceramics and nanostructured materials − under dynamic loading. Special features of the destruction of materials and dependence on their composition and impact velocity from 1 to 6 km/s are…
Mn-doped TiO2 thin films were produced by spin coating on FTO glass substrates to investigate the effects of Mn concentration on the structural, morphological, and optical properties of the films. Titanium isopropoxide and manganese chloride tetrahydrate were used as titanium and manganese sources respectively, in the…
La9.33+x/3Si6−xAlxO26 (0 ≤ x ≤ 2.0) sinters with an apatite-type crystal structure were synthesized by solid-state reaction at 1600°C for 5 h, and the sintered discs were examined by AC impedance analysis and X-ray Diffraction (XRD). The total conductivity was significantly increased with an increase in the Al-content…
The detection of carbon is conducted by laser-induced breakdown spectroscopy (LIBS) in a flow system designed to replicate aircraft exhaust flow conditions. To generate carbon particles, a glucose solution was evaporated using a ceramic nebulizer and an electrical heater. For elemental analysis, both the C (247.86 nm)…
The effect of the presence of dissolved ferrous ions (Fe 2+ (aq)) on oxide film growth and conversion on Type-316L stainless steel in pH 8.4 borate solutions was studied by a range of electrochemical and surface imaging and spectroscopic analysis techniques. The results provide a consistent picture of the anodic oxida…
Investigation into Electrochemical Oxygen Reduction on Platinum in Tetraethylammonium Hydroxide and Effect of Addition of Imidazole and 1,2,4-Triazole, Sarkar, A., Zhu, X., Nakanishi, H., Kerr, J. B., Cairns, E. J.
A liquid-liquid separation method using aqueous and oil phases has been put forward for separation of fine zircon-alumina mixtures to recycle abrasives waste. By using a cation surfactant, zircon particles were made hydrophobic and extracted into the oil phase, whereas alumina remained in the aqueous phase. In this wa…
Reconstruction of the Main Cylinder of Carding Machine-Optimization of Dimensions with the Use of the Finite Element Method The following paper presents the solution to the problem of searching the best shape - structural form of the bottoms and optimal dimensions of the main cylinder of the carding machine with consi…
The development of new technologies applied to hydrogen thermal compression is oriented to the design of reversible hydride forming compounds that reach the desired pressure conditions by modifying the temperature. Particularly, the main efforts are focused on the research of multi substituted AB5 compounds. In this w…
Group BIII (Al, In)-, BV(Bi, Sb) and BVI(Te, Se)-doped Mg2Si compounds were synthesized by solid-state reaction and mechanical alloying. Electronic transport properties (Hall coefficient, carrier concentration and mobility) and thermoelectric properties (Seebeck coefficient, electrical conductivity, thermal conductivi…
A process for the fabrication of Al2O3–YAG eutectic composites using an undercooled melt formed by the melting of an Al2O3–YAP eutectic specimen has been developed. An Al2O3–YAG eutectic structure with fine lamellar spacing was formed. However, the Al2O3–YAG casting has porosities with diameters of 4–9 µm. The composi…
Structural and elemental modifications of multiferroics evolve promising optical, electronic and magnetic properties. In this work, we report two new quaternary compounds (KxBi1−xFeO3−y) with nanowire and microrod structures synthesized based on potassium modification of BiFeO3 by polyethylene glycol (PEG) and hexadec…
Until now, describing yarn structure has been more art than science, especially for complex yarns and cordage like those encountered at Cerrillos, a Paracas (ca. 900-100 B.C.E.) site in the Ica Valley of Peru, where yarns and cordage frequently involve multiple colors, sub-structures, and materials (e.g., Image 1). My…
Multilayers of2wt-% Pr-and4wt-% BaZrO3-doped YBa2Cu3O6+x (YBCO) were deposited by pulsed laser ablation on SrTiO3 and MgO single crystals. The structural and superconducting properties of the multilayers are presented. Multilayering was found to improve the critical temperature and structural quality of the samples on…
The effect of nitrogen-containing substituents such as phenyl imide and actyl imide on the character of fragmentation of perylene derivative molecules under laser irradiation has been studied by laser desorption (LD) mass spectrometry. Replacement of the central oxygen atom by a nitrogen atom in anhydride carboxy grou…
Bulk heterojunction photovoltaic devices, which use the conjugated polymer poly(2‐methoxyl‐5‐(2′‐ethylhexyloxy)‐1,4‐phenylenevinylene) (MEH‐PPV) as the electron donor and crystalline ZnO nanowires as the electron acceptor, have been studied in this work. The ZnO nanowires were prepared through a chemical vapor deposit…
