Effective use of catalysts through catalyst regeneration
The refining industry is currently undergoing its most serious challenge in recent times, since cleaner fuels are gradually introduced in many markets. Middle East countries still have less history than Europe, Japan or the USA when it comes to clean fuels, but the trend is there, which will eventually increase the demand for hydroprocessing catalysts. On the other hand, more sophisticated cata...

15 صفحه اولSelective endo and exo binding of alkali metals to corannulene.
The ion size matters: the structures of corannulene monoanions crystallized with Cs(+) and Rb(+) ions in the presence of [18]crown-6 reveal the intrinsic binding preferences of alkali metals and allow evaluation of the bowl deformation caused by negative charge distribution and metal binding. The large cesium cation coordinates exclusively to the concave face of C(20) H(10)(-), whereas the smal...

Nano/Micro-Patterning of Semiconductors by Site Selective Chemical Etching Using Noble Metals as Catalyst
Controlled silicon structures on the micron to nanometer order have received much attention owing to their potential applications in various fields such as electrochemical, optoelectrical, and biological sciences. Although the techniques commonly used in fabricating nano-/microstructured silicon are conventional lithographic techniques using a resist mask with an optical, electron, or X-ray bea...
