The purpose of this work was to determine the radiolytic hydrogen gas yield of irradiated CSSX solvent at several temperatures. The active ingredient of this solvent is calix[4]arene-bis-(t-octylbenzo) crown-6, a calixarene crown ether used for cesium complexation. The solvent also contains 1-(2,2,3,3-tetrafluoropropo…
A fundamental study is conducted to evaluate dynamic fracture and failure in functionally graded materials (FGM) at room and high temperatures. Asymptotic analysis in conjunction with displacement potentials is used to develop thermo-mechanical stress fields for a mixed mode propagating crack in homogenous and FGMs. F…
The chemistry of octahedral rhenium chalcogenide molecular cluster is a field at the crossroads of organic/inorganic hybrid materials and solid state chemistry. These compounds are known for their electronic and photo-active properties. The first part of this work is concerned with the use of [Re6Se8(CN)6]4- as an oct…
Das Baulos LT33 des Lainzer Tunnels der ÖBB Infrastruktur Bau AG bildet einen Teil der Verbindungstunnelstrecke zwischen West- und Südbahn. Dieser Abschnitt liegt zur Gänze in den Gesteinen der Flysch- und der Klippenzone. Der Tunnelabschnitt wird der Kahlenberger Decke und der St. Veiter Klippenzone zugeordnet, wobei…
In vielen Situationen ist es nützlich, von komplizierten Objekten eine einfachere Gestalt zu kennen. In dem folgenden kleinen Abschnitt wollen wir uns mit der ursprünglich aus der Theorie der Kegelschnitte stammenden Frage beschäftigen. ob beliebige quadratische Matrizen eine solche einfache Form besitzen und wie man…
The Purposes of this research were detects correlation prosentase subtitusi aggregate slag concrete quality optimum, where does soft aggregate use and coarse from slag as proper aggregate to fulfill a concrete construction with special spesification. aggregate use slag can optimize deposit solid slag from steel fusion…
Ce travail est consacre a l'etude experimentale et numerique du comportement mecanique des materiaux polymeres semi-cristallins, en l'occurrence le polypropylene. Ces materiaux sont souvent destines aux pieces de securite dans le domaine de l'automobile. Ils ont l'avantage d'etre peu onereux et d'avoir une bonne resis…
The Metal Injection Moulding (MIM) process is suitable for producing relatively small and complex components that require high strength and cost viability. This process, carried out in large batches, produces high density, complex and accurate shaped parts. This study attempts to optimise the processing parameters for…
A UV-curable tung oil alkyd (UVTA) was prepared from tung oil-based alkyd.The tung oil-based alkyd was synthesized via the monoglyceride process and then reacted with trimethylolpropane trimethacrylate (TMPTMA) via Diels-Alder cycloaddition.The tung oil-based alkyd and UVTA were characterized using 1 H NMR, 13 C NMR a…
In cryo-electron microscopy (cryo-EM) single-particle reconstruction, projection images of many first order structural identical copies of the specimen of interest are combined to recover the underlying three-dimensional object. The analyzed particles are embedded in vitreous ice in a hydrated state at many random ori…
Rice is the most important grain crop in China, and the paddy field is one of the main sources of methane (CH4). It is essential that we should sustain the increase of rice yield under the energy-saving condition and at the same time limiting the emission of methane. This paper reviews the studies on direct/indirect e…
Des catalyseurs Pt/C pour piles a combustible ont ete prepares par des methodes colloidales. Des etudes par ATG, ATG-SM, MET et DRX de 323 a 573 K ont ete realisees sous atmosphere oxydante et reductrice pour mimer les conditions de travail d'anodes et de cathodes de PEMFCs et pour accelerer le processus de vieillisse…
Interfacial surface phenomenon and treatments has been exhaustively explored for the semiconductor industry for advanced material surface preparation. The RCA clean process is a standard for the IC industry1. Unfortunately, the needs for the photovoltaic (PV) industry are different in scope and purpose. Exploring the…
Hydrogenated amorphous a-SiC:H and a-SiCN:H with different nitrogen-concentration dielectric barrier films are prepared using the plasma-enhanced chemical vapor deposition technique （RF-PECVD）. The chemical and structural nature, mechanical property, dielectric constant and copper diffusion property of these films are…
To Prisca, for all the help and hard work on the Water
In the present paper, the preparation and properties of Eu(III) on poly(N-isopropylacrylamide-co-acrylic acid) (P(NIPAM-co-AAc)) were described. At first, P(NIPAM-co-AAc) microgel nanoparticles were prepared by the precipitation copolymerization of N-isopropylacrylamide with acrylic acid in the presence of N, N-methyl…
Over the last decade, polymers reinforced with natural fibres composites have been getting an increasing attention from the academic world and various industries. Natural fibres are prospective reinforcing materials and their usage until now has been more traditional than technical. The attractive features of natural…
Diese Arbeit präsentiert und diskutiert die Ergebnisse einer Reihe verschiedener mineralogischer und geochemischer Untersuchungen an Grafitgesteinen der Böhmischen Masse. Diese sind Träger sulfidischer Mineralisationen und treten innerhalb der Drosendorf-Formation auf, welche sich als schmales Band von Persenbeug nord…
Three kinds of metal-oxide-semiconductor high-electron-mobility transistors （MOS-HEMTs） with different thickness of Al2O3 dielectric layer were fabricated on the same wafer by atomic layer deposition. The measurement results of MOS capacitance，gate leakage current，and the output and transfer characteristics indicate t…
Surface chemical composition of water atomized steel powders prealloyed with manganese, was investigated with regard to composition, morphology, size and distribution of surface oxides. The oxides formed on the powder surface were studied by means of surface analytical techniques (XPS, SEM and EDX). Dependence of surf…
