Sugar-based biosurfactants are safer and healthier alternatives to synthetic surfactants especially for use in the food industry. In this work, biosurfactants were synthesized via the esterification of lactose with lauric acid in different organic solvents without using lipase or other enzymes. ...

Aluminosilicate solid acid catalysts, especially zeolites, have been widely utilized in petroleum refinery and environmentally benign chemical processes. The acidic property of aluminosilicates has been a subject of advanced studies. Recently an ammonia IRMS-TPD (infrared/mass spectroscopy tempe...

A general synthetic strategy for the preparation of atomically dispersed, well-defined Lewis acidic aluminum sites in silicate matrices is described and illustrated. These amorphous matrices are composed of the spherosilicate cubes (Si8O20) linked together by combinations of aluminum and siloxan...

Some particular hazardous and nuclear wastes containing a large amount of chlorine would cause the problematic processing during the waste vitrification, because of the low solubility of Cl in silicate glasses. Although a few works reported the chlorine behavior in aluminosilicate glasses, the r...

Natural alkali-rich aluminosilicates minerals from Harmancık/Bursa/Turkey and Kepsut/Balıkesir (Turkey) were characterised by X-ray diffractometry (XRD), X-ray fluorescence (XRF) and investigated the blue thermoluminescence (TL) emission of the samples. The TL glow curves exhibited a very comple...

Twenty pitchblendes have been dated by the Xes−Xn spectrum technique. Most of the ages obtained are in good agreement with ages obtained by the UPb isotopic technique. Age spectra of these samples have the typical “step up”-form. When the Xes−Xen and UPb ages are discordant, age spectra ar...

A sample of pitchblende from Congo was found to contain (4±1) × 10−15 grams of 147Pm per kg of ore. The 147Pm/U ratio in the pitchblende was (3±1) × 10−4 disintegrations per second per gram of uranium. The observed 147Pm/U ratio in the pitchblende was in agreement with the 147Pm/U equilibriu...

Length-weight relationships (LWRs) and relative condition factor are of great importance in fishery assessment studies since it provide information about the growth of the fish, its general wellbeing, and fitness in a marine habitat. LWRs for 9 fish species collected from the marine area of Trip...

With the growing interest in using the continuous-energy TRIPOLI-4® Monte Carlo radiation transport code for ITER applications, a key issue that arises is whether or not the released TRIPOLI-4 code and its associated nuclear data libraries are verified and validated for the D–T fusion neutronic...

This paper presents an overview of TRIPOLI-4®, the fourth generation of the 3D continuous-energy Monte Carlo code developed by the Service d’Etudes des Réacteurs et de Mathématiques Appliquées (SERMA) at CEA Saclay. The paper surveys the generic features: programming language, parallel opera...

Tripoli is a microcrystalline siliceous rock used to polish metals and precious stones. Its inhalation has been associated with increased prevalence of breathing complaints and pneumoconiosis. However, its acute human exposure has not been so far studied. We aimed at evaluating the putative mech...

The International Thermonuclear Experimental Reactor (ITER) is currently under construction in France. From the radiation shielding and radiation protection points of view, an intense and large neutron source with energy around 14.1 MeV will be generated from the D-T plasma zone during the ITER ...

For the future ITER (International Thermonuclear Experimental Reactor) operation needs, D-T fusion experiments named DTE2 will be conducted in 2020 at JET (Joint European Torus). During the DTE2 operations, 14 MeV fusion neutrons will be generated. One of the aims of the DTE2 neutronics experime...

BackgroundDiabetes mellitus is a complex, chronic, metabolic disease manifested in hyperglycemia and associated with various complications, Consequently, people with diabetes have higher rates of hospital admissions than the general population. There is little information about the burden of hos...

Recent research shows that street-level noise represents one of the main noise sources in urban spaces. The noise source includes various transportation modes, human activities and environmental sounds, such as the wind and rain. Continuous exposure to high-level noise may lead to health and psy...

Roman red slip ware uncovered at Tripolis, an ancient city of Lydia region in modern Denizli province, Turkey, was analyzed for geochemical and mineralogical properties in order to clarify their manufacturing technology. Samples were examined by optical microscopy, X-ray powder diffraction, and ...

Optical absorption and EPR studies of the mineral tenorite, a cupric oxide which originated from Mexico and contains 54.40 wt% of CuO. EPR spectral results indicate two Cu(II) closely interacting ions to give a d2 type structure. The calculated spin Hamiltonian at room temperature and liquid nit...

Photocatalytic colour enhancement of Methylene Blue (MB) and Rhodamine B (RhB) dye is achieved by dual band gap Titania Tenorite (TiO2/CuO) nanocomposite system prepared by a cost effective co-precipitation method. The UV–Visible and XPS analyses reveal that the existence of dual band gap is du...

Aim is to assess the anti-biofilm property of tenorite nanoparticles and to study their suitability as a possible coating material for medical implants. Tenorite (CuO) nanoparticles were synthesized by the optimized thermal decomposition method and characterized using TEM, XRD, FTIR and UV–Vis ...

A gel type polystyrene/divinylbenzene anion exchanger containing quaternary ammonium groups was used as the macromolecular support for copper(II) compounds deposition, whereby novel hybrid anion exchangers were obtained. The anion exchanger in the OH− form was subjected to two-step transformatio...
