DIRECTED EVOLUTION OF ENZYMES: SMALL CHANGES, BETTER BIOCATALYSTS
(Soc Brasileira Quimica, 2020-06-01)
Biocatalysis is now a mature field, both in the laboratory and industrial scale. This approach counts on enzyme high selectivity, biodegradability, elegant control over the outcome of reaction conditions and as a possible ...
A model of the Fermi surface for antiferromagnetic europium metal
(1973)
Energy gaps near the Fermi surface arising from magnetic Brillouin zone effects must be taken into account in order to understand the antiferromagnetism of europium metal. © 1973 Pergamon Press.
DES-mediated approaches toward green analytical chemistry
(Wiley VCH Verlag, 2019)
Over the last few years, environment protection and human health and safety have gained considerable attention in the field of analytical chemistry. In this sense, green analytical chemistry (GAC) have emerged, bringing ...
The development of an environmentally benign sulfide oxidation procedure and its assessment by green chemistry metrics
(Royal Society of Chemistry, 2009-02)
Different Iron (III) species were used as catalysts in sulfoxidation reactions giving excellent yields and high chemoselectivity. Among the iron (III) species, the best one was a solid β-cyclodextrin-FeBr3 complex. ...
