The possibility of the determination of the elemental composition and concentrations of unknown hydrocarbon components in a mixture without performing calibration per each mixture component was shown using gas chromatography with atomic emission detection.
The interaction of ethylene with the catalytic particles, ion pairs Cp 2 ZrMe + A – (Cp = η 5 -C 5 H 5 , A – = MeAl(C 6 F 5 ) 3 – or (C 6 F 5 ) 3 Al–Me–Al(C 6 F 5 ) 3 – ), has been investigated. The participation of two molecules of Al-containing activator in the formation of a...
An organized mesoporous CuO–Al 2 O 3 composite was synthesized using a sol-gel based self-assembly technique; unfolded polyethyleneimine supramolecular formations were employed as a structure-directing agent. The formation mechanism of a well- organized composite structure is explained.
Liquid crystalline phthalocyanine bearing eight oligo(ethyleneoxy) peripheral substituents forms homeotropically aligned films on the hydrophilic surface, whereas planar alignment with a random distribution of the column directors occurs on the hydrophobic surface.
The spatial modulations of the degree of polymerization of an oligomer in the layer of liquid photopolymerized compositions can initiate diffusion leading to the rise of surface landscape.
In order to reveal the nature of intermediates of peroxide oxidation catalysed by vanadium compounds, the inner-sphere transformations of vanadium(V) peroxo complexes with the general formula (VO 6 ) – has been studied in approximations of the density functional theory (B3LYP/6-31G**) and...
Thiacalix(4)arenes containing the phthalimide group were synthesized and their extraction ability toward monocharged cations (alkali metals and Ag + ) was investigated.
Na x MnO 2 · n H 2 O birnessite was used to yield one-dimensional nanostructures of manganese dioxide and effect of its chemical composition on electrochemical performance in lithium cells was studied.
The electrochemical reduction of a mono-chelate palladium dichloride complex with 1,2-bis(diphenylphosphino)ethane (dppe) in DMF results in formation of highly reactive mono-chelate palladium(0) complex, which reacts with initial complex by reaction of the ligand abstraction forming stable...
The paper reported a new quantitative method for the determination of calcium pantothenate, basing on its perturbation effects on the new Belousov–Zhabotinskii oscillating system.
