The aim of this study was to investigate the effects of electron beam (EB) irradiation on the morphological properties, crystallinity and surface area of henequen fiber and on the mechanical and thermal properties of henequen fiber reinforced polypropylene (PP) composites. The structure of henequen fiber was character…
It is important for the understanding of the complexity of a human hair structure to observe the ultra-structures and to measure their mechanical properties at the same point of the specimen. We examined the extremely smooth surface of the hair cross-section by force modulation (FM) method and Young's modulus mapping…
V-SBA-15 materials prepared using a hydrothermal methodology were found to be highly active and selective in the oxidation of a range of alkanes under mild reaction conditions. The activities of the systems were compared under conventional and microwave heating. Microwave experiments demonstrated that the long times o…
Silver hexynyl cluster cations, [(C(4)H(9)CCAg)(n)Ag](+), exhibit a rich unimolecular chemistry that is dependant on the cluster size, n (1-5), cluster fragmentation (for all n > 1); C-C bond coupling (n = 3 & 4); C-H bond activation with comcomitant silver hydride formation (n = 1 & 4); C-C bond activation (n = 1 & 4…
The preparation of entrapped CdSe?ZnS fluorescent quantum dots (QDs) in cucurbituril (CB) polymer capsules is reported.
Nanocrystalline tungstate-exchanged layered double hydroxides of the takovite type, [Ni(x)Al(1-x)(OH)(2)](NO(3))(0.9-x)(WO(4))(0.05).mH(2)O, have been prepared with changing values of x. The morphology-texture parameters of the synthesized materials were characterized by using scanning electron microscopy and nitrogen…
The molecular properties and surface morphology of undoped and N‐doped ultra‐nanocrystalline diamond (UNCD) films deposited by microwave plasma CVD with addition of nitrogen are investigated with various spectroscopic techniques. The results of spatially resolved Raman scattering, ATR/FT‐IR and XPS spectra show more a…
Two heterometallic polynuclear complexes, [Cd2(OAc)6(μ-O)Cu4(dmae)4]·H2O (1) and its zinc analogue [Zn2(OAc)6(μ-O)Cu4(dmae)4]·3H2O (2), were synthesized by simple chemical techniques. These complexes were characterized by their melting point, elemental analysis, FT-IR, APCI-MS and single crystal X-ray diffraction. The…
The paper outlines the method and the results of the experimental investigation of interlaminar strength of glass fibre reinforced polyester composites, with the aim of determining the influence that the structure, a reinforcement type and a sort of resin exert upon the interlaminar strength. The tested specimens were…
A series of polymeric formulations has been prepared based on oxobiodegradable (PVA) and hydrobiodegradable (starch, PLA, Bionolle) macromolecular materials used as continuous matrices and fillers derived from a marine sea-weed (Zostera). The formulations have been submitted to processing trials under different experi…
CuCo co-doped ZnO nanorods have been synthesized via a soft chemistry route without using any surfactant, seed and catalyst. Structural analyses reveal that the samples of nominal compositions Cu0.01Co0.02Zn0.97O and Cu0.02Co0.01Zn0.97O have single hexagonal wurtzite structure without forming any extra secondary phase…
C / β -SiC / Si hybrid microtubes have been fabricated by releasing prestressed C/Si bilayer structures and treating with a postannealing process. Detailed characterization reveals the synthesis of β-SiC via a solid phase reaction at the C/Si interface. Remarkably, the production of β-SiC is promoted in the tube wall…
Abstract Bibliometric methods, in particular citation analysis, are used to evaluate the International Journal of Materials Research (IJMR) and its two predecessor journals Zeitschrift für Metallkunde (ZfM) and Internationale Zeitschrift für Metallographie (IZfM). Firstly, the coverage of the journals by the various l…
Ultrafine-grained materials, having grain sizes in the submicrometer or nanometer range, may be readily produced by processing bulk solids through the application of severe plastic deformation (SPD) and this leads to the possibility of revealing different flow mechanisms when these materials are tested at elevated tem…
Structural characteristics and thermal behaviour of the conventionally solidified Al–Cu–Fe alloys with nominal compositions of Al70Cu20Fe10, Al65Cu20Fe15 and Al63Cu25Fe12 were investigated by X-ray diffraction, scanning electron microscopy, and differential thermal analysis techniques. Results show that a single quasi…
The (SYCM) oxide with a cubic perovskite structure was examined as a promising cathode material for intermediate temperature solid oxide fuel cells (IT-SOFCs). The electrical conductivity, thermal expansion coefficient (TEC), and reactivity with gadolinia-doped ceria (GDC) or yttria-stabilized zirconia (YSZ) were stud…
The dehydration behavior of the paraelectric phase of was investigated by thermogravimetric and X-ray diffraction analyses, and then the phase diagrams of system were established. The relationship between the onset temperature of dehydration and the partial pressure of water is below . The thermodynamically stable pha…
