The iron compounds resulting from the impregnation of the most common supports—alumina and silica gel-with an aqueous FeSO 4 · 7H 2 O solution and subsequent heat treatment in air are identified by thermal analysis and Mössbauer spectroscopy. The state of the active component of the iron-containing catalysts depends s…

We investigate the local structural change under antiferro- and ferromagnetic transition for annealed Fe 50.4 Rh 49.6 alloy. Both Fe and Rh K -edge EXAFS are analysed up to second nearest neighbours. For first nearest neighbour Fe-Rh (or Rh-Fe), the temperature dependence of the interatomic distance and Debye-Waller f…

We present results of tight binding calculations demonstrating existence of degenerate electronic shells of Dirac fermions in narrow, charge neutral graphene quantum rings. We predict removal of degeneracy with finite magnetic field. We show, using a combination of tight binding and configuration interaction methods,…

Ground tyre rubber (GTR) was blended with waste polypropylene (WPP) in nine different compositions to prepare GTR/WPP blends. The blends were prepared in a Haake Rheocord PolyLab system at a temperature of 180 °C and a rotor speed of 30 r/min for 8 min. The processing characteristics of the blends showed an increase i…

One of the main reasons for using nonceramic insulators in polluted regions is the reduction of maintenance needed to keep a line in service. Because the useful lifetime of these insulators depends largely on the pollution conditions, it is advisable to inspect the insulators on a regular cycle. The article discusses…

The authors developed an experimental method that can measure the in-plane thermal conductivity of a thin film and the interface thermal conductance between the film and the metal strip, simultaneously. This technique, the in-plane 3ω method, can be applied to the films with very high thermal conductivity such as diam…

Most commercial textile materials are given a “soft finish” for the comfort of the wearer. This paper investigates the effects of two levels of concentration for six commercial softeners on cotton knitted fabrics. The fabric properties are measured by using the Kawabata Evaluation System for Fabrics (KES-FB). It is fo…

The I ( V ) characteristics of amorphous GST devices show a peculiar S-shape behavior, that is a swift rise of the current along with a voltage snap-back. This type of characteristics led to a growing research interest in view of the future application of such materials to the manufacturing of phase-change memory devi…

In situ x-ray absorption spectroscopy identified partially oxidized platinum as the active phase for generating high activity during carbon monoxide oxidation over Pt/Al 2 O 3 . CO covers and poisons metallic platinum, which results in a low catalytic activity. The conversion in CO abruptly increased during ignition,…

Abstract Mg–Al layered double hydroxide intercalated with 2,7-naphthalene disulfonate ion (2,7-NDS·Mg–Al LDH) was prepared by coprecipitation and was found to selectively take up aromatic compounds from aqueous solutions. The amount of material absorbed by 2,7-NDS·Mg–Al LDH depends on the electron-donating or -withdra…

The spectra of RE-doped YPO 4 (RE = Ce 3+ , Pr 3+ or Nd 3+ ) have been measured. The spectroscopic and decay kinetics properties of pure host YPO 4 were also studied at 8 K and 300 K, which indicated the host had taken part in the luminescent processes of activators. Under the excitation over the bandgap of the host,…
