Abstract To overcome the severe toxicity and blind absorption zone of conventional lead-based shielding materials for X-rays in 70–90 keV range, lead-free multilayered polymer composites were designed fabricated. The effects direction incidence number layers as well layer thickness ratio (tungsten/ethylene-octene copolymer)/(bismuth/ethylene-octene copolymer) layered on their efficiency studied...

The Oxidative Coupling of Methane (OCM) to ethylene is a promising alternative for the oil based industry. In this process, beside the valuable product ethylene, other by-products are produced. Hence the gas stream has to be refined further. The process is not applied in the industry yet, because of high separation costs. This article focuses particular on the CO2 purification of the OCM produc...

Polysome profiles were examined from lyophilized peel tissue of ripening pear (Pyrus communis, L. var. Passe-Crassane). Messenger RNA chains bearing up to eight ribosomes (octamers) were resolved and exhibited the highest absorption peak when ribonuclease activity was eliminated during extraction. Neither normal ripening nor the increase of large polyribosomes that normally accompanies ripening...

Dual beam thermal lens technique is successfully employed for the determination of absolute fluorescence quantum yield of rhodamine 6G laser dye in different solvents. A 532 nm radiation from a Q-switched Nd:YAG laser was used for the excitation purpose. The fluorescence quantum yield values are found to be strongly influenced by environmental effects. It has been observed that fluorescence yie...

We present an Fe Kα resonant inelastic X-ray scattering (RIXS) and X-ray emission (XES) study of ferrous and ferric hexacyanide dissolved in water and ethylene glycol. We observe that transitions below the absorption edge show that the solvent has a distinct effect on the valence electronic structure. In addition, both the RIXS and XES spectra show a stabilization of the 2p levels when dissolve...

In this work, casting method was used to fabricate the polyvinyl alcohol (PVA)/ poly ethylene glycol (PEG) nanocomposite with different content of titanium nitrate nanoparticle (TiN NPs). This analyzed use a Spectrophotometry spectral region 200-800 nm. The absorption enhances when added TiN NPs polymeric matrix which may be for various applications such as optoelectronic detector. optical ener...
