Pyrochemical separation technology using high-temperature molten salts presents a potential interest for an overall separation strategy. Pyrochemical R&D program, launched at CEA, aims at demonstrating the feasibility of a grouped separation of actinides with sufficient decontamination. The process is based on two liq…

Employing a semi-rigid di-1,2,4-triazole ligand leads to the formation of new MOFs [Cu(4)(L)(4)(SO(4))(4)]·4[Cu(H(2)O)(6)(SO(4))] (3) and [Cu(6)(L)(3)(SO(4))(5)(OH)(2)(H(2)O)(6)]·13H(2)O (4). The frameworks can be synthesized independently, but a reaction occurs in water wherein kinetic product 3 is used as a reagent…
In this study effect of adding various process control agents (PCAs) to powder mixtures of Al and TiO 2 which are mechanically activated so as to form TiAl - Al 2 O 3 nano-composite have been investigated. Phase constitutions and morphology of the milled powders were evaluated by XRD and SEM techniques, respectively.…
In this study, chromium zirconium nitride (Cr-Zr-N) thin films have been prepared by reactive dc closed field unbalanced magnetron co-sputtering on Si (100) wafers and glass slides for 60 min without substrate heating and biasing voltage in gas mixture of Ar and N2 with flow rates kept constant at 3.0 sccm and 6.0 scc…
Photocatalytic activity of KTaO3 catalyst to water splitting is much improved by organic dye-modification. In particular, cyanocobalamin (Vitamin B12) is the most effective for improving water splitting activity, and the formation rate of H2 and O2 are achieved values of 1912 and 979 μimol gcat“’h”1, respectively, und…
It is difficult to deposit extremely thin a-Si:H layer in heterojunction with intrinsic thin layer (HIT) solar cell due to thermal damage and tough process control. This study aims to understand oxide passivation mechanism of silicon surface using rapid thermal oxidation (RTO) process by examining surface effective li…
We have investigated the effect of adding CdSe quantum dots (QDs) with their hexadecylamine (HDA) ligands coating in ITO/SPT/P3HT:PCBM/Al bulk heterojunction (BHJ) organic photovoltaic cells (OPV). At first, we found that the optimal thermal treatment was a post cathode deposition annealing, due to an effective surfac…
Self-assembled monolayers (SAMs) of hexadecanethiol (HDT) and 16-mercaptohexadecanoic acid (MHDA) were used to vary the surface chemical properties, and oleic acid (OA) was used as a lubricant. A pin-on-disk tribometer equipped with Fourier transform IR (FT-IR) spectroscopy was used to evaluate the results of lubrican…
Nano/Submicron crystalline grains of about 250 nm were obtained in a metastable austenitic stainless steel AISI304L by an advanced thermomechanical process consisting of heavy conventional cold rolling and annealing. Effects of cold thickness reduction and temperature and time of the reversion treatment on microstruct…
LiNi 1/3 Mn 1/3 Co 1/3 O 2 cathode material is synthesized by reactions under autogenic pressure at elevated temperature (RAPET) method and its electrochemical behavior is studied in 5 M LiNO 3 aqueous solution and compared with that in a nonaqueous electrolyte. In cyclic voltammetry, LiNi 1/3 Mn 1/3 Co 1/3 O 2 electr…
To investigate the proton transport properties of the Nafion thin films on MgO(100) substrates, impedance measurements of the 60 and 400 nm thick thin films were carried out. The proton conductivity of two thin films were quite lower values compared to that of the commercial Nafion membrane, and the thickness dependen…
Two poly(vinyl chloride) matrix membrane electrodes responsive to some drugs affecting the cardiovascular system, Amlodipine besilate (AM) and Valsartan (VL), were developed, described and characterized. A microsized graphite selective sensor was investigated with dibutylsebacate (DBS) as a plasticizer in a polymeric…
Based on the platform ABAQUS, a 3-D FEM model of conical ring with outer steps ring rolling process has been developed to investigate the ring's deformation behavior and the equivalent plastic strain PEEQ distribution. During the ring rolling, the average equivalent plastic stain (PEEQa) is increasing with bigger idle…
Power quality is one of the major concerns in the present era. It has become important, especially, with the introduction of sophisticated devices, whose performance is very sensitive to the quality of power supply. To solve this problem, custom power devices are used. One of those devices is the Dynamic Voltage Resto…
The [Cs((2 + x))][H(3)O((1 - x))]Tc(2)Br(8)·4.6H(2)O (x = 0.221) salt has been synthesized and characterized by single crystal XRD. Multi-configurational quantum chemical calculations on Tc(2)X(8)(n-) (X = Cl, Br; n = 2, 3) have been performed and indicate the π component in the Tc-Tc bond to be stronger for n = 3.
Linoleic acid (LA) is converted to per-carboxylic acid catalyzed by an immobilized lipase from Candida antarctica (Novozym 435). This per-carboxylic acid is only intermediate and epoxidized itself in good yields and almost without consecutive reactions. Monoepoxide linoleic acid 9(12)-10(13)-monoepoxy 12(9)-octadecano…
Sleep is an essential physiological activity for human beings and many studies have so far investigated sleeping comfort of mattresses. The appropriate measurement of stress distribution within the human body would provide valuable information to us. For the appropriate measurement to estimate stress distribution with…

Bamboo charcoals were prepared by low temperature carbonization at 500 °C, and subsequent treatments such as air oxidation at 180-380 °C for the introduction of functional groups on the surface, and outgassing at 1000 °C for their removal were conducted to examine the relationship between the amount of water vapor ads…
