The biomimetic nature of micellar catalysis can significantly affect the rate of chemical reactions due to the effects of concentration and the change of microenvironment. A novel supramolecular catalytic system bazed on ...

Filtering of weak pulses through a medium with infinite periodic structure in the absorption and/or transmission spectrum is analyzed. Two types of filters are considered. The first, named harmonic frequency crystal (HFC), ...

The statistics of the fractional moments (SFM) and discrete geometrical sets/invariants (DGI) were appl ied for explain of the temporal evolution of the electrochemical background. The set of the quantitative parameters ...

Thin films of iron with different thickness (⁓40-300 nm) were deposited on quartz and silicon substrates by using ion beam assisted deposition (IBAD) technique. The influence of film thickness and deposition rate on ...

In bulk, face-centered gamma-iron exists only at temperatures above 917 ?C, returning back to body-centered alpha-iron upon cooling below this temperature. In this work, we report formation of the gamma-iron phase at ...

The catalytic activity of electrochemically synthesized zirconium carboxylates was studied in the process of ethylene oligomerization. Zirconium carboxylates were electrochemically synthesized directly from metallic zirconium ...
