Carbon-carbon bond cleavage of 1,2-diphenyl-ethanes in CH3OH-H2SO4-H2O electrolyte on a boron-doped diamond (BDD) electrode has been investigated electrode using 1,2-di-(p-tert-butylphenyl)-ethane and 1,2-dimethoxy-1,2-di-(p-tert-butylphenyl)-ethane as mod ...
The relation between the catalyst potential and the catalytic performance has been investigated in the gas-phase combustion of propylene with oxygen over rhodium catalysts at 375 DegC. The rhodium catalyst, deposited on yttria-stabilized zirconia (YSZ) sol ...

Semi-continuous direct-chill (DC) casting of aluminium ingots suffers from a very frequent defect which can lead to a strong decrease in productivity: hot tearing. This phenomenon takes place in the mushy state (i.e., at solid fractions, gs, lower than uni ...
This study investigates the influence of petroleum hydrocarbons on a microbial community in the vadose zone under field conditions. An artificial hydrocarbon mixture consisting of volatile and semi-volatile compounds similar to jet-fuel was emplaced in a p ...
Hybrid Car-Parrinello QM/MM calcns. are used to investigate the reaction mechanism of hydrolysis of a common b-lactam substrate (cefotaxime) by the monozinc b-lactamase from Bacillus cereus (BcII). The calcns. suggest a fundamental role for an active site ...
In this thesis, the electrochemical promotion of lr and Rh based catalysts was studied for the complete combustion of ethylene and propylene. The study was performed by using two types of electrocatalytical cells: a classical, pellet type cell and a tubula ...
Novel efficient structured combustion catalysts based on sintered metal fiber filters (MFF) were developed. To increase sp. surface area (SSA), metal fibers were coated by crack-free porous oxide films of SiO2, Al2O3, porous glass, and mesoporous SBA-15 si ...
Due to human activities, organic pollutants are spilled to the environment where they threaten public health, often as contaminants of soil or groundwater. Living organisms are able to transform or mineralize many organic pollutants, and bioremediation tec ...
The role was studied, of bulk V2O5 in vanadia/titania catalysts in partial oxidn. of toluene. Two catalysts with 1.8 and 11.1% of V were studied, by in situ DRIFTS and transient-response methods. Bulk V2O5 was found by FT-Raman spectroscopy only in the 11. ...
