Tunable spin and transport in porphyrin-graphene nanoribbon hybrids [PDF]
arXiv, 2022 Recently, porphyrin units have been attached to graphene nanoribbons (Por-GNR) enabling a multitude of possible structures. Here we report first principles calculations of two prototypical, experimentally feasible, Por-GNR hybrids, one of which displays a small band gap relevant for its use as electrode in a device. Embedding a Fe atom in the porphyrin

Interlocking nodal chains and their examples in carbon networks [PDF]
Carbon 157, 563 (2020), 2020 Nodal chain is a typical topological phase in nodal line semimetals. Here, we propose a new topological phase -- interlocking nodal chains, in which two sets of nodal chains are interlocked each other. It includes one- (1D), two- (2D) and three-dimensional (3D) versions, which can be produced by a three-band model.

Intoxicação com anestésicos locais: revisão de literatura
Revista Intertox de Toxicologia Risco Ambiental e Sociedade, 2018 Os anestésicos locais realizam o bloqueio da condução nervosa, interferem na função de todos os órgãos nos quais ocorre condução ou transmissão de impulsos nervosos. No entanto, podem causar intoxicação nos sistemas nervoso central e cardiovascular.
