Using electrodeposition from a bath of molten fluorides, single crystals of tetragonal beta-tantalum have been obtained for the first time at normal pressure. The unit-cell parameters are a = 10.211 (3), c = 5.3064 (10) Angstrom, space group P (4) over bar ...
Liquid metal embrittlement (LME) is illustrated on the Cu-Bi and Cu-PbBi systems at 300 C using either constant strain-rate tests at 10(-4) s(-1) or constant load tests at 25% of yield stress. Intergranular penetration was studied in the Ni-Bi system at 70 ...
The use of filamentous catalysts for innovative design of chemical reactors with structured catalytic beds is discussed in detail. The fluid dynamics attained in such reactors avoid transport limitations (mixing or heat- and mass-transfer) and increase rea ...
A microchannel reactor specially designed for periodic operation and a process to deposit a catalyst, g-alumina, inside the reactor channels were developed. The hydrodynamics of the reactor was characterised. Although the flow in the microchannels is lamin ...
The photocatalyst for the use in the production of hydrogen from water or aqueous solutions of organic compounds by using light energy, comprises carbon, in addition to a semiconducting photocatalytic material. The photocatalytic apparatus for the producti ...

Catalytic hydrogenation of NO2- in water to N2 over Pd-supported on different woven fibrous materials was studied. Low porosity C fiber, low porosity D-type glass fiber, and composite (glass covered by g-Al2O3) fiber were used. Pd dispersion was compared f ...
Industry requires continuously new chemical processes to convert raw materials to valuable products limiting the formation of by-products. Since a few years, an increasing interest has been given to the intensification of chemical processes. This represent ...
A theor. anal. is presented for the prediction of the specific energy consumption and the required electrode surface for the electrochem. combustion of org. compds. on synthetic B-doped diamond thin film electrodes. The model is formulated for a perfect mi ...
An anisotropic structured fixed-bed divided into 2 reactor parts is a bundle reactor consisting of fiber-bundle. The fiber-bundle ordered in the flow direction are formed from filaments; the diam. of the fiber-bundle is smaller than its length and bigger t ...

The Buss-Kneader is generally known as a compounding device. Although a reasonable number of papers have been published on extruders as polymerization reactors, only little is known about the behavior of the Buss-Kneader when used as a polymerization react ...
