The focus of the present research is to develop an integrated deformation and recrystallization model for magnesium alloys at the microstructural length scale. It is known that in magnesium alloys nucleation of recrystallized grains occurs at various microstructural inhomogeneities such as twins and localized deformat…
Polyacrylonitrile-based carbon nanofibers (CNFs) containing Ti and Mn were prepared by electrospinning. The effect of metal content on the hydrogen storage capacity of the nanofibers was evaluated. The nanofibers containing Ti and Mn exhibited maximum hydrogen adsorption capacities of 1.6 and 1.1 wt%, respectively, at…
In this Letter thin films of zinc oxide (ZnO) are prepared by sol–gel method and deposited on glass substrate to evaluate structural and optical properties of the film. The films were grown at different thicknesses in the range of 100–180 nm. The properties of layers were characterised using X-ray diffractometer (XRD)…
We performed femtosecond reflection spectroscopy on a series of A-site ordered perovskite-type cobalt oxide $R$BaCo${}_{2}$O${}_{6\ensuremath{-}\ensuremath{\delta}}$ ($R=\text{Sm}$, Gd, and Tb) crystals, in which the electronic transfer was controlled by $R$. The transient reflectivity and the optical conductivity [${…
We performed total energy and electronic structure calculations for the basic ground state properties of Fe using the conventional generalized gradient approximation (GGA) and screened hybrid functionals as the form of the exchange-correlation functional. To that end, we calculated structural (equilibrium lattice cons…
Abstract In this study, glass fiber reinforced polyester composites were coated with carbon nanofiber/clay/ammonium polyphosphate (CCA) paper and carbon nanofiber/exfoliated graphite nanoplatelets/ammonium polyphosphate (CXA) paper. The composites were exposed to a heat flux of 35 kW/m 2 during the cone calorimeter te…
In this Letter the authors study a liquid detector based on Ag nanoparticles for dosimetry purposes. They use two different concentrations of silver nitrate (1 mM AgNO3) and sodium citrate (1 and 0.1% C6H5O7Na3) as precursors for the formation of Ag nanoparticles in an aqueous colloidal solution. The authors utilise a…
In this work, rosuvastatin has been used to gain insight into the molecular basis of statin photosensitization. This lipid-lowering drug, also known as "superstatin", contains a 2-vinylbiphenyl-like moiety and has been previously described to decompose under solar irradiation, yielding stable dihydrophenanthrene analo…
Hierarchical ZnO superstructures assembled by ZnO nanorods have been successfully constructed in mixed solvents of ethylene glycol (EG)–water via a facile hydrothermal method. ZnO nanostructures with dumb-bell-like and microsphere morphologies were obtained by only a change of the precursor concentration. The products…
Ag/Au bimetallic nanoparticles possess the combinatory advantages of Au and Ag nanoparticles and can also be utilized to tune the properties of localized surface plasmon resonance. Ag/Au bilayer nanorods were prepared by electron beam lithography, and their spectral properties were investigated. Compared with Ag monol…
Conducting polymer-coated multiwalled carbon nanotubes (MWCNTs) were prepared by template polymerization in order to enhance their gas sensitivity. This investigation of the conducting polymer phases that formed on the surface of the MWCNTs is based on field-emission scanning electron microscopy images. The thermal st…
Kenaf fibers, cellulose-based natural fibers, were used as precursor for preparing kenafbased carbon fibers. The effects of carbonization temperature (<TEX>$700^{\circ}C$</TEX> to <TEX>$1100^{\circ}C$</TEX>) and chemical pre-treatment (NaOH and <TEX>$NH_4Cl$</TEX>) at various concentrations on the thermal change, chem…
CuO nanorods were synthesised on a large scale via a simple hydrothermal method. CuCl2·2H2O and cetyltrimethylammonium bromide (CTAB) were used as the copper source and surfactant, respectively. The microstructure and morphology of the CuO nanorods were examined by X-ray diffraction, Raman spectrum, field-emission sca…
The use of carbon nanotubes (CNTs) as a reinforcing material in a polymer matrix has increased in various industries. In this study, the flexural behavior of CNT-modified epoxy/basalt (CNT/epoxy/basalt) composites is investigated. The effects of CNT modification with silane on the flexural properties of CNT/epoxy/basa…
The suitability of the current resilient modulus test protocol (NCHRP 1-28A) for its application to unsaturated soils was assessed. Modifications to the stress state conditions of the protocol are necessary due to the axis-translation needed during the test when measuring matrix suction. This study presents the modulu…
This paper deals with the up-conversion intrinsic photoluminescence by exciting the Metallo-Phthalocyanine (MPc) prepared by melt method. MPcs were further characterized using UV visible spectrophotometer, FT-IR, and thermal analysis. The magnetic susceptibility, optical absorption and photoluminescence behavior of th…
Polyaniline nanocomposite was prepared in aqueous media by polymerization of aniline using ((NH4)2S2O8) as an oxidant in the presence of dioctyl phthalate (DOP). Also polyaniline/polystyrene (PAn/PS) nanocomposite was prepared in the aqueous solution by polymerization of styrene and aniline using potassium iodate (KIO…
Resonant ultrasound spectroscopy (RUS) was used to analyze the elastic and anelastic behavior associated with canted antiferromagnetic ordering at 36 K in the radical, $\ensuremath{\beta}$-$p$-NCC${}_{6}$F${}_{4}$CNSSN, 1. On cooling through the magnetic ordering transition there is anomalous elastic behavior away fro…
Los Argyrolagoidea (Mammalia, Marsupialia, Polydolopimorphia, Bonapartheriiformes) muestran un patrón de contactos cuspidales durante la oclusión dentaria completamente diferente a cualquier otro grupo de marsupiales sudamericanos. El patrón resultante de facetas de desgaste es también exclusivo para este grupo. Esto…
Semiconductor–noble metal hybrid nanostructures are of current interest in the development of bioimaging agents. To enhance photoluminescence of cadmium sulfide nanoparticles via surface plasmon mode coupling, cadmium sulfide conjugated silver nanoplates (denoted as CdS-Ag NP) have been prepared by a forward–reverse c…
