Layer Deposition

This work demonstrates a mechanistic study of iron oxide deposited by ALD, revealing a growth mechanism involving uptake of superstoichiometric oxygen. Material characterization shows ozone exposure can be used to convert the crystallographic phase and domain orientation of the materials. This mechanism has implications for wider classes of ozone-based ALD processes and can generalize to other systems.<br>

Entropy Effect

The importance of various surface imperfections in the nucleation of ice crystals iR considered and it is concluded that dislocations are not preferred nucleation sites, whereas steps and re-entrant corners do encourage nucleation. Expressions are derived for the height of the free energy barrier in several important cases, and the retention of embryos under unsaturated conditions is discussed. Embryos initially grow by twodimensional nucleation, but ultimately a dislocation growth mechanism becomes more important. There is not yet enough experimental evidence to decide upon the reality of the entropy effect, previousl:y- proposed, which inhibits nucleation upon certain CITRta] faces.

Excellent Method

Cu(i) catalyzed carboxylation of the C–F bond is an excellent method for construction of complex fluoroacrylate compounds with high regioselectivity. Here, theoretical calculations were carried out to investigate the detailed mechanism and origin of regioselectivity.
