The chemical composition of the zinc bath can strongly influence on the hot-dip galvanized coatings. In this work, the effects of tin addition on the surface morphology, and the corrosion resistance of hot-dip galvanized steel were investigated. The corrosion behavior of steel samples galvanized with zinc and Zn-Sn al…
Interface magnetic anisotropy of Co2FexMn1−xSi Heusler alloy thin films were studied quantitatively. Films of Co2MnSi (x = 1, CMS), Co2Fe0.5Mn0.5Si (x = 0.5, CFMS), and Co2FeSi (x = 1, CFS) were fabricated onto MgO (001) substrates with an epitaxially grown Pd (001) under layer, and were capped by an MgO layer. The ma…
We prepared in this work an anchoring porphyrin and a series of hat-porphyrins. The zinc atom of the hat-porphyrins can be coordinated axially with the pyridine moiety of the anchoring porphyrin which is anchored on the titania surface by a carboxyl group. The structures of the assemblies were confirmed using computat…
We here use first-principles calculations to investigate the phase stability of the hypothetical laminated material V2Ga2C and the related alloy (Mo1-xVx)2Ga2C, the latter for a potential parent material for synthesis of (Mo1-xVx)2C, a new two-dimensional material in the family of so called MXenes. We predict that V2G…
LOB3, a naturally-occurring orbitide, is capable of self-assembling into 1D nano-fibers and ultimately 3D molecular gel networks in acetonitrile.
Styrene oxidation mediated by a Mo-based mesoporous catalyst can yield selectively styrene oxide or benzaldehyde. Kinetic data evidenced that styrene oxide is the initial single-product formed by the catalytic Mo-mediated process. However, after some hours of reaction benzaldehyde yield rises while that of the epoxide…
The authors compare IR spectra of diamonds of different origins, both natural and synthetic ones—produced by detonation, dynamic, and static syntheses, and subjected to purifying treatment under various conditions. It is shown that in the IR-spectral range there are absorption bands at 421, 945, 1022, 2854, 2920, and…
The control of spin without a magnetic field is one of the challenges in developing spintronic devices. Here, based on first-principles calculations, we predict a new kind of ferromagnetic half-metal (HM) with a Curie temperature of 244 K in a two-dimensional (2D) germanene van der Waals heterostructure (HTS). Its ele…
Nanostructured membranes of anodic aluminum oxide (AAO) with InP/ZnS semiconductor nanocrystals deposited in pores were synthesized by electrochemical technique, physical deposition and post processing in an ultrasonic bath. Photoluminescence spectra of the samples were studied. Fluorescent properties of the quantum d…
We use Onsager theory and the local density approximation to study sedimentation-diffusion equilibrium density profiles of binary mixtures of thick and thin hard rods. We construct stacking diagrams for three diameter ratios, and find that even a simple spindle-shaped phase diagram with only isotropic-nematic demixing…
A new approach is proposed for creating of pH-sensitive mesoporous silica nanocontainers with ultrahigh capacity for amphiphilic functional compounds.
Upon blue excitation, acac-modified solutions present significantly higher luminescence compared to unmodified ones due to the presence of pre-nuclei of YAG:Tb structure which is very interesting for using them for optical applications.
ZnS:Mn/NaGdF <sub>4</sub> :Yb:Er nanocomposite was synthesized using a single-step hot injection method and then applied in the downconversion and upconversion optical imaging of living HeLa cells.
Recently, new compounds Mn2RuSn and Mn2RuSi were synthesized and their crystal structures were studied by X-ray diffraction measurements. This measurement indicates that they have a Heusler-like cubic structure, but the details have been unclear so far. To clarify their atomic arrangement and magnetic order, we carrie…
To improve the productivity of Paraphoma-like fungal strain B47-9 for biodegradable plastic (BP)-degrading enzyme (PCLE), the optimal concentration of emulsified poly(butylene succinate-co-adipate) (PBSA) in the medium was determined. Emulsified PBSA was consumed as a sole carbon source and an inducer of PCLE producti…
Chitin and Chitosan have been produced from shrimp byproduct by chemical method.Shrimp byproducts were collected from fish processing point.The process of chitin extraction from shrimp waste was involving demineralization with 2% (v/v) HCl solution (10:1 v/w, 30ºC, 12h), then de-proteinization with 4% (w/v) NaOH solut…
The inhibitive action of some azoles (1,2,4-triazole, 1,2,3-benzotriazole, 5-chlorobenzotriazole, and IFKhAN-92 corrosion inhibitor) on the corrosion of magnesium was investigated in aqueous buffer solutions and humid atmosphere.Increasing the hydrophobicity and decreasing the pK a of NH-acids enhance the protection o…
Textured α-alumina ceramics were prepared by mixing different ratios of three-sized plate-like α-alumina particles and fine equiaxed particles without the use of sintering aids. The plate-like particles have developed a-b planes and were incorporated as an aligned template. Mixed powders were formed into a green sheet…
Since the launch of the Materials Genome Initiative by the US government in 2011, many computer techniques have been developed to predict the structures and properties of advanced materials, providing important guidance for laboratory experimentation and a promising new direction for future materials innovation. Howev…
The Research on thermostability of flame-retardant materials is of great significance for a reasonable choice of flame retardant and optimization material properties. In this paper, the PyGC is adopted to study the thermostability of flame-retardant-PC/ABS-blends added different types of fire retardants. PC/ABS sample…
