Abstract The dissolution of corn stover in alkaline solvent system composed of NaOH-H2O2 was reported and the separation of its ingredients combined with acid precipitation, ethanol extraction was proposed. It is proven that the residual after alkali solvent was cellulose, the filtrate by the acid precipitation of the…
Under the complex environment of soils, rocks and underground water, the challenges in the repair and maintenance of urban metro structures confront engineers daily. The use of microcapsule-enabled self-healing cementitious composite has high potential as a new repair method for cracked concrete under complex service…
In this research three groups of polymer blends have been prepared First groupincluded (Polystyrene (PS): Low density polyethylene (LDPE))While the Second group(included Polystyrene (PS): Polypropylene (PP)) and Third groups include (Polystyrene (PS): Poly methel methacrylate(PMMA)) are prepared in different ratios by…
Catalytic effect of Al(OH) 3 on the hydrogen generation from Al/water system is evaluated. The Al(OH) 3 powders are synthesized from various molar ratios of Al(NO 3 ) 3 : NaOH = 1:3 ~ 1:5. It was found that the Al(OH) 3 catalyst derived from the ratio Al(NO 3 ) 3 : NaOH = 1:3.5~1:4 in an ice bath exhibits the best cat…
Abstract A new yttrium-zirconium-pillared montmorillonite (Y-Zr-MMT), was synthesized, characterized and used as a Ce catalyst support. The Y-Zr-MMT is a good support for dispersing cerium active sites and it is responsible for the high activity in the total oxidation of acetone, toluene and ethyl acetate. The Y-Zr-MM…
In this paper, plate-like NiO nanoparticles were prepared by one-pot solid-state thermal decomposition of nickel (II) Schiff base complex as new precursor. First, the nickel (II) Schiff base precursor was prepared by solid-state grinding using nickel (II) nitrate hexahydrate, Ni(NO3)2∙6H2O, and the Schiff base ligand…
Despite numerous studies conducted on the lower limit of soil and its contact with saprolite layers, a great deal of work is left to standardize identification and annotation of these variables in the field. In shallow soils, the appropriately noting these limits or contacts is essential for determining their behavior…
Abstract In 2013, the World Health Organisation (WHO) released an update of the report on “Priority Medicines for Europe and the World” with the aim to bridge the gap between public health needs and the current research and development priorities. A number of emerging technologies are currently explored for their pote…
Many microfluidic devices, also known as lab-on-a-chip devices, employ electrochemical detection methods using microelectrodes. Miniaturizing electrodes inevitably reduces electrode sensitivity and decreases the S/N, which limits applications within microfluidic devices. However, microelectrode surface modification ca…
Abstract The newREE-rich, monoclinic, epidote-supergroup minerals ferriakasakaite-(La) and ferriandrosite-(La), found in tephroite calcite veinlets cutting the stratiform ferromanganese deposit from the Shobu area, Ise City, Mie Prefecture, Japan, were studied using electron microprobe analysis and single-crystal X-ra…
Summary Polyaniline (PANI) based composites and multilayers as well as porphyrin derivatives have been previously reported as efficient anti‐corrosion coatings. In our studies, 5,10,15,20‐tetra(4‐methylphenyl)‐21H,23H‐porphyrin (TMP) was adsorbed on carbon steel surface before PANI electrodeposition, in order to impro…
Raman scattering and second-harmonic generation processes in porous layers obtained by the electrochemical etching of polycrystalline silicon carbide, which contain nanocrystals with dimensions from several to hundreds of nanometers, have been studied. It has been found that the efficiencies of Raman scattering and se…
Multi-winding transformers as main part of multiport phase shift converters play an important role in integration of renewable energy sources, storage device and loads. The range of power transfer in multi-port phase shift converters particularly depends on the leakage inductance of multi-winding transformer. Numerica…
β-type Ti alloys containing Nb are exciting materials for numerous orthopedic and dental applications due to their exceptional mechanical properties. To improve their cytocompatibility properties (such as increasing bone growth and decreasing infection), the surfaces of such materials can be optimized by adding elemen…
Catalytic reforming accounts for a large share of the world’s gasoline production, it is the most important source of aromatics for the petrochemical industry. In addition, reforming of hydrocarbon on the dual-function catalysts has been found to form fundamentally different products in hydrogen diluents. Typical cata…
The magnetic Barkhausen effect is useful for assessing 1D and 2D stress states of ferromagnetic steel objects. However, its extension to technically important materials, such as duplex anisotropic steels, remains challenging. The determination of magnetisation inside the studied object and the electromagnet for variou…

RESUMO Filmes biodegradáveis à base de proteínas de soro de leite apresentam grande potencial para aplicação como embalagens, devido às suas excelentes propriedades mecânicas e ópticas. Contudo, alguns processos, como a aplicação de radiação gama, podem afetar as propriedades físicas, mecânicas e cor dos filmes produz…
Composites with a copper matrix, reinforced by carbon nanotubes, have been produced by the multistage method including functionalization of carbon nanotubes, their dissolution, mixing with a copper powder, preliminary warm isostatic compaction, and severe plastic deformation by torsion. The microstructure and microhar…
The structure and the magnetic transitions have been investigated as a function of Mn in stoichiometric Ni2MnGa heusler alloys. Particular attention is paid to examine the linear increase of martensite transformation temperature on substituting Mn for Ga. It is observed that the martensite temperature increases and Cu…
