We report on the interesting properties of a novel single precursor, Cd(tta)2 x tmeda (Htta = 2-thenoyl-trifluoroacetone, tmeda = N,N,N',N'-tetramethylethylenediamine), ideally suited for the selective and reproducible fabrication of pure quality films of CdS or CdO through a simple solution process.
Monitoring of fast transformations in solid state chemistry and heterogeneous catalysis by QEXAFS in the second scale, Lützenkirchen-Hecht, D, Grunwaldt, J-D, Richwin, M, Griesebock, B, Baiker, A, Frahm, R
Article on the solubility of crystalline nonelectrolyte solutes in organic solvents and the mathematical correlation of 3-chlorobenzoic acid solubilities with the Abraham solvation parameter model.
The performance of the conventional low‐energy CD‐SEM is limited by the aberrations inherent in the probe forming lens. Multi‐pole correctors are now available which can reduce or eliminate these aberrations. An SEM equipped with such a corrector offers higher spatial resolution and more probe current from a given ele…
Biopolymers formed from crosslinking of different proteins is an area of growing interest. Much has been reported in the literature on the properties of a variety of biopolymers synthesized by enzymatic treatment. These products have the advantage of possessing the unique properties of each protein and have the potent…
The aim of the work was the selection of the most suitable method for fracture surface analysis using modern tools for mathematical verification of a dataset containing irregular data values and considerable variability of amplitude. The Hurst exponent was used for the verification of the analyzed dataset. The propose…
Canonical correlation analysis was applied to the study of interrelationships between two multivariate datasets, one consisting of available and exchangeable potassium content, and second consisting of pH, hydrolytic acidity, and content of exchangeable aluminum, calcium and magnesium, available phosphorus, and total…
Porous implants having interconnecting channels allow ingrowth of host connective tissue. Complete implant vascularization reduces the risk of infection, extrusion, and other complications associated with nonintegrated implants. We developed 60% and 70% porous Ultra High Molecular Weight Polyethylene (UHMWPE) plates a…
In this paper, a new method for obtaining partial discharge (PD) characteristic based on ultra-high frequency (UHF) measurements is presented. According to electromagnetic theory, the PD electromagnetic radiation can be regarded as the dipoles radiation. Based on which, the radiation model of partial discharge pulse c…
Organic silicon compounds (siloxanes) contained in wastewaters tend to accumulate in sewage sludges, and during sludge treatment in digester tanks, they are released into the digester gas. When digester gas is burned in gas engines, silicone-containing deposits are formed, which lead to greater wear and tear and may d…
The structures and performances of the native kapok fibers were studied.The kapok fiber has thin wall and huge lumen,the hollow ratio can reach 97%.One end of the fiber tapers to one point and is closed,and the other end is bulbous shape and may be closed tightly.The bulk density of the fiber is 0^30 g/cm3.The kapok f…
The products from Fischer-Tropsch synthesis process, without S, N and aromatic hydrocarbons, are clean and environmentally friendly. But they contain a large number of alkene and oxygenates, especially acid oxygenates, which erode equipment and need to be hydrorefined. Therefore, the study on the novel hydrodeoxygenat…
Biodegradable plastics have received great attention in polymer industries from the ecological view point. A number of plastics with biodegradability properties have been developed over the recent decades. In this study, several types of biodegradable plastics were selected: poly (butylene succinate) homopolymer (PBS)…
o C with a thin layer of an adhesive) are increased 38%, 209% and 267%, respectively. The reason behind this significant enhancement is demonstrated to be relat- ed to the debond strength of the core-face interface. It has been demonstrated that the debond strength of the core-face and core plays an important role in…
Dielectric spectroscopy measurements below 1 Hz are often dominated by "conduction-like" effects. For this reason, they often appear to be dismissed as being of little interest. In this paper two "sub-hertz" responses are considered that give insights into the insulating systems concerned. The first system is that of…
Aviation fuel is a petroleum product that fulfills the Standard Specification for Aviation Turbine Fuels. Crude oil has been the raw material for production of aviation fuels for many years. Since the availability of crude oil is predicted to be limited in the future, alternative raw materials for aviation fuels are h…
The effect of ultraviolet light (UV) irradiation (254 nm, 0.8 mW/cm 2 ) on air-formed oxide films and passivated films on iron was investigated by electrochemical methods and scanning tunneling microscopy (STM), in particular with respect to surface micro/nanostructures and the surface protective property. An as-depos…
We have first recalled the T (LIESST) procedure which consists to determine the temperature above which the photo-magnetic effect is erased. In addition we have selected to series of iron(II) spin crossover complexes, the [Fe(PM-L) 2 (NCS) 2 ] and [Fe(bpp) 2 ]X 2 ·nH 2 O families, to analyse the influence of the coope…
Abstract The effect on AA2024‐T3 of a non‐chromate deoxidizer based on Fe(III)–HF–HNO 3 has been examined by atomic force microscopy, x‐ray photoelectron spectroscopy and scanning electron microscopy. Magnesium and silicon present on the surface after alkaline cleaning was removed very rapidly at room temperature. The…
Planar structures consisting of oxidized copper granules obtained by laser electrodispersion are studied. The samples have different packing densities of granules and different amounts of their chains and aggregates. Each granule 5.5 ± 0.5 nm in size consists of a copper core with an amorphous structure and an oxide s…
