Spin‐Split Edge States in Metal‐Supported Graphene Nanoislands Obtained by CVD
Advanced Materials, EarlyView.Combining STM measurements and ab‐initio calculations, we show that zig‐zag edges in graphene nanoislands grown on Ni(111) by CVD retrieve their spin‐polarized edge states after intercalation of a few monolayers of Au. ABSTRACT Spin‐split states localized on zigzag edges have been predicted for different free‐standing graphene nanostructures.

Secretory Phospholipases A2 in Plants [PDF]
, 2019 Secreted phospholipases (sPLA2s) in plants are a growing group of enzymes that catalyze the hydrolysis of sn-2 glycerophospholipids to lysophospholipids and free fatty acids. Until today, around only 20 sPLA2s were reported from plants.

Communication: UV photoionization of cytosine catalyzed by Ag+ [PDF]
, 2015 The photo-induced damages of DNA in interaction with metal cations, which are found in various environments, still remain to be characterized. In this paper, we show how the complexation of a DNA base (cytosine (Cyt)) with a metal cation (Ag+) changes ...

Boletim de Indústria Animal, 2014 Este trabalho foi realizado com o objetivo de evidenciar eventuais diferenças na composição quÃmica da leucena, perante duas intensidades de desfolha. O tratamento 1, sujeitando as plantas a desfolhas periódicas originou uma maior preponderância de material vegetal jovem, originando diferenças significativas nas análises bromatológicas ...

Dual antibacterial effect of immobilized quaternary ammonium and aliphatic groups on PVC [PDF]
, 2015 A coating comprising quaternary ammonium salts (QAS) and aliphatic moieties was formed on the poly(vinyl chloride) (PVC) surface in order to confer antibacterial activity. This was achieved by grafting mercaptopropyltrimethoxysilane onto PVC, followed by
