Spin‐Split Edge States in Metal‐Supported Graphene Nanoislands Obtained by CVD
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]
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.

Em delineamento experimental Inteiramente casualizado, 21 bovinos machos da raça santa-gertrúdis, com idade inicial de trinta dias, foram distribuÃdos em três tratamentos e sete repetições. Os tratamentos foram: castração quÃmica, castração cirúrgica e ausência da prática. A castração quÃmica consistiu na aplicação intratesticular de

A high‐capacity polyimide‐linked porous organic polymer (HAT‐PTO) incorporating numerous redox‐active centers is synthesized via a hydrothermal reaction, delivering a high theoretical capacity of 484 mAh g−1. In situ hybridization with carboxyl‐functionalized multiwalled carbon nanotubes enhances conductivity and stability, achieving 397 mAh g−1 at C ...

Communication: UV photoionization of cytosine catalyzed by Ag+ [PDF]
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 ...

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 ...

The new Cu‐containing MOF (Me2NH2)(CuICl2)@[Cu4(INA)4Cl2O]·1.5dmf (3) contains a cation and an anion as guests and shows UV‐near‐mid‐IR absorption and near‐IR emission. MOF 3 shows gas‐solid reactivity in the presence of NH3 and HCOOH to yield two new 3D MOF.

Dual antibacterial effect of immobilized quaternary ammonium and aliphatic groups on PVC [PDF]
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
