One-dimensional (1D) semiconductor nanomaterials attract much attention because they are ideal systems for investigation and studying the relationship between properties and structures and having extensive application future in the high technical field. They are expected to play an important role in fabrication of the…
Impact of partitioning, transmutation and waste reduction technologies on the final nuclear waste disposal
Abstract: Raisin is one of the most important products in terms of agriculture exports. During storage period, the product turns sticky and hard due to exudates syrup and moisture loss. To overcome this problem the application of edible coating suggests being of proper assistance. Edible coating is defined as a thin l…
The need for sustainable materials is today an undeniable fact given the negative effects associated with the disposal of plastics. Additionally, the urgent need to enhance recycling abilities of high volume non-degradable plastics such as PET, PC and Nylon has driven the development of additives called “chain extende…
The surface morphologies and structural information of several slice crystals grown by the physical vapor transport (PVT) method were investigated using atomic force microscopy (AFM) and X-ray diffraction (XRD) analysis. Step-like structures were observed by AFM, corresponding with XRD results and the characteristics…
Paclitaxel (PTX) is an antitumor agent for the treatment of various human cancers. Cremophor EL and ethanol are used to formulate PTX in commercial injection solutions, because of its poor solubility in water. However, these agents cause severe allergic reaction upon intravenous administration. The aim of this study i…
The electronic structure of the organic semiconductor titanyl phthalocyanine (TiO-Pc) has been investigated using synchrotron radiation-excited X-ray emission and absorption spectroscopies. The C and N K-edge spectra display similarities with those recorded from other metal-Pcs, while the O K-edge and Ti L-edge spectr…
Carbon, like Si, is an attractive and very versatile engineering material and is available in more structural varieties than Si. Carbon materials are already in use in a wide variety of applications because of their widely differing crystalline structures and properties, which enable very different physical, chemical,…
Hyperbranched polyglycerols 1 and 2 have been synthesized from pentaerythritol and glycidol in a one-pot process by anion ring-opening polymerization. These polymers are modified easily to sulfate or carboxylate-based polyglycerols 3–5 with the SO3–Py complex and sodium chloroacetate, respectively. Polyglycerols 3–5 h…
Sidewall functionalization of single-walled carbon nanotubes (SWNTs) via the Heck cross-coupling reaction of pre-functionalized p-iodophenyl SWNTs allows the covalent binding of different groups such as alkyl chains, dialkylamino or anthracenyl moieties. Functionalized SWNTs were characterized by a set of methods incl…
Abstract Plasma polymerization covers a broad range of plasma deposits from soft to hard coatings. Nanoscale coatings are formed within a dry and eco-friendly process on different substrate materials and structures. To gain a deeper insight into plasma polymerization, a macroscopic approach using the concept of chemic…
SUMMARY The main objective of the present paper is the development of thermo-elasto-viscoplastic constitutive model of a material which takes into consideration induced anisotropy effects as well as observed contribution to strain rate effects generated by microshear banding. Physical foundations and experimental moti…
Abstract The objective of the present study is development of novel surface-active block, comb-like, and branched copolymers with peroxide-containing chains, as well as derived functional luminescent and magnetic nanoparticles. The main experimental approaches are based on tailored synthesis of the oligoperoxide surfa…
The adsorption of NO and CO was studied on an alumina-supported palladium catalyst by in situ diffuse reflectance infrared spectroscopy (DRIFTS). The temperature range was 50-160 degrees C and a wide variety of partial pressures was used. The band-target entropy minimization (BTEM) algorithm was applied to the DRIFTS…
The ?-? phase transformation in Si3N4 was studied for seeded samples using an Y2O3-Al2O3 mixture as a sintering aid. The concentration of ?-seeds varied from 0 to 5 wt.%. The results showed that ?-? phase transformation followed the first-order reaction. The calculated activation energy for seeded samples was in the r…
The Potentiometric Cycling for Polymorph Creation [PC] 2 has been applied to sparfloxacin, a third-generation fluoroquinolone antibiotic. Two different trihydrate phases precipitate from aqueous solution. X-ray data indicate that one of these is a previously unknown polymorph of sparfloxacin trihydrate. Because both f…
Carbon-based electrode materials have been widely used for many years for electrochemical charge storage, energy generation, and catalysis. We have developed an electrode material with high specific capacitance by entrapping graphite nanoparticles into a sol-gel network. Films from the resulting colloidal suspensions…
The synthesis of binuclear organometallic ruthenium complexes of an expanded porphyrin-type macrocycle is reported; pyrrolic hydrogen bonding donors were found to interact with ancillary ligands in the primary coordination sphere and to stabilize coordinated dioxygen in an eta(2)-fashion.
Multistage mass spectrometry (MS(n)) experiments reveal that gas phase silver iodide cluster cations, Ag(n)I(m)(+), are readily built up in a stepwise fashion via ion-molecule reactions between mass selected silver (Ag(3)(+) and Ag(5)(+)) or silver hydride (Ag(2)H(+) and Ag(4)H(+)) cluster cations and allyl iodide, in…
A 1,3-phenylene linked poly(phenothiazine cation radical) was synthesized and its through-bond spin interaction was investigated. Monomer and dimer models were also synthesized to investigate the behaviour of spins in poly(phenothiazine cation radical). X-Ray crystallographic analysis of the monomer model showed that…
