We investigate the electronic properties of blue-phosphorene nanotubes using density functional theory first-principle calculations, taking into account, in particular, the presence of atom vacancies in the structure. The study considers both zigzag and armchair achiral configurations and reports on the structure and the electron energy states of the nanostructure. Compared to pristine blue-phosphorene nanotubes, which exhibit values of the fundamental bandgap between one and two electron-volts. For atomic single vacancies, the incorporation of spin-polarization helps to identify the induction of localized mid-gap states in the blue phosphorene nanotubes. The difference of energy between the highest near-valence and lower near-conduction localized states is, approximately, of 0.5 eV. Also the increase of the single vacancies concentration leads to the formation of additional bands that change the energy gap of the system.

“…Whereas the reversed micelle is water droplets dispersed in organic solvents with the help of surfactant stabilization. The surfactant molecule is usually having two different parts in their structure; the polar hydrophilic head and their hydrophobic tail that is susceptible to the interaction with the organic phase [58][59][60] . The waterin-oil microemulsion was introduced for the preparation of colloidal Cu 2 [Fe(CN) 6 ] solutions with the assistance of sodium bis(2ethylhexyl) sulfosuccinate (AOT) surfactant from a facile reaction of CuSO 4 with K 4 [Fe(CN) 6 ].…”

“…[2][3][4][5] Nos métodos eletroanalíticos, pode-se avaliar por exemplo, a concentração de analitos eletroativos, os mecanismos de reação, a partir de fatores como diferença de potencial, intensidade de corrente e acúmulo interfacial de carga. 2,6,7 A rapidez nas detecções, a alta sensibilidade, a seletividade e o baixo custo das medidas eletroquímicas, refletem o vasto campo de suas aplicações e técnicas (Figura 1). As diversas aplicações podem ser encontradas em sistemas de biossensores, 8,9 investigações criminais (química forense), 10,11 avaliação de parâmetros no meio ambiente, 12,13 entre outras.…”

Electrochemical sensors are analytical tools that offer great portability, ease automation, miniaturization capability, and low cost compared to other analytical techniques and methods. For those reasons, there is a growing search for these electrodes to obtain better analysis conditions. This advance is reflected in new patents and articles, which were intensified mainly with the arising of chemically modified electrodes and self-sufficient equipment. Besides, this study brings together and discusses the main aspects of electrochemical methods, the development of electrodes and their modifiers, as well as the perspectives for these electroanalytical tools. Os sensores eletroquímicos são ferramentas de análise que oferecem maior portabilidade, facilidade de automação, capacidade de miniaturização e baixo custo em relação a outras técnicas e métodos analíticos. Por essas razões, existe uma crescente busca pelo desenvolvimento desses eletrodos a fim de se obter melhores condições de análise. Esse avanço reflete em novas patentes e artigos que se intensificaram, principalmente com o surgimento dos eletrodos quimicamente modificados e equipamentos autossuficientes. Em suma, esse estudo reúne e discute aspectos fundamentais concernentes aos métodos eletroquímicos, o avanço no desenvolvimento dos eletrodos e seus modificantes, além das perspectivas para essas ferramentas eletroanalíticas.
