O que é nanotecnologia?

A nanotecnologia, que foi revelada por Norio Taniguchi na Universidade de Tóquio em 1974, é rapidamente tecnologias emergentes baseadas na sensibilidade mais avançada e redução das tecnologias existentes. No futuro, esta tecnologia provavelmente incluirá maquinaria estrutural e mecanismos com suas dimensões nano-sized, chamadas nanotecnologias moleculares (MNT). A nanotecnologia é usada para medir uma unidade de medida denominada nanométrica (formulário curto nm). Cada medida tem 1.000.000.000 nm. Cada nm é de apenas três a cinco átomos de largura, ou seja, aproximadamente 40000 vezes menor do que a espessura de um cabelo humano médio.



 

Um aspecto da nanotecnologia

 

Super pequenos computadores (de tamanho de bactérias)

 

Super computadores com um tamanho de açúcar cúbico e bilhões de laptop Power

 

É possível fazer modelos de desktop nano-sized de um determinado tamanho que são trilhões mais poderosos do que os computadores de hoje.



 

O alto potencial da nanotecnologia é revelado através das leis da física quântica. Nesta fase, as leis de física quântica são ativadas em tamanhos nano e permitem novas aplicações em óptica, eletrônica, armazenamento magnético, computação, catalisador e outras áreas.



 

A nanotecnologia é muitas vezes referida como tecnologia de uso geral. Porque quando é realizado, a nanotecnologia terá um lugar importante em quase todos os setores e em todas as áreas da sociedade. Os produtos mais bem feitos, mais duradouros, mais limpos, mais seguros e mais espertos podem ser usados em casa, na comunicação, na medicina, no transporte, na agricultura e em todas as áreas da indústria.



 

Imagine um instrumento médico que pode ser encontrado sem espalhar células cancerosas circulando no corpo humano, ou é muito mais leve do que o aço, mas é um material que é dez vezes mais forte do que é.



 

Por que a nanotecnologia deve ser usada com cautela e sensibilidade? A nanotecnologia, como a electricidade ou os computadores, irá oferecer melhores possibilidades em todas as fases das nossas vidas. No entanto, como em todas as novas tecnologias, a nanotecnologia tem duas vias de uso, ou seja, uso comercial e muito mais poderosas armas e ferramentas de vigilância devido à nanotecnologia no campo militar. É por isso que a nanotecnologia também traz alguns riscos, juntamente com os benefícios para as pessoas.



 

Um dos lados importantes da nanotecnologia é que ele não só oferecer melhores produtos, mas também ferramentas de produção mais aprimoradas. Um computador pode copiar arquivos de dados tanto quanto você quer a um custo muito baixo ou de graça. Ele pode torná-lo tão fácil e barato para replicar os mesmos arquivos como o mesmo exemplo de computador em nanotecnologia. É por isso que a nanotecnologia é referida como a próxima revolução industrial para muitos.



 

A nanotecnologia permitirá não somente a produção de muitos produtos de alta qualidade a um custo muito baixo, mas igualmente para fazer fábricas nano novas a baixo custo e na mesma velocidade elevada. A razão pela qual nano tecnologia é chamada de uma tecnologia ràpidamente crescente é a capacidade de reproduzir suas próprias ferramentas de produção.



 

Nanotecnologia; Fornece um sistema de produção mais rápido, mais baixo do custo e do Clean. As ferramentas de produção podem ser reproduzidas multiplicando-se, assim que diversas fábricas nano produzirão biliões de fábricas dentro de algumas semanas. Este é um revolucionário, inovador, poderoso e potencialmente muito perigoso ou tecnologia útil.



 

Quando todos esses desenvolvimentos podem acontecer?

 

As estimativas gerais são de que pode ser entre 20 e 30 anos ou mesmo mais tarde. Mas os avanços rápidos em óptica, nano litografia, química mecânica e tecnologias de prototipagem 3D pode encurtar este tempo. O que é importante aqui não é apenas como tal melhoria pode ser feita em um curto espaço de tempo, mas também como estamos prontos para esta nova tecnologia.



 

Talvez quando perguntarmos a nós mesmos algumas das seguintes perguntas, podemos perceber melhor. Quem vai possuir esta tecnologia?

 

Isso é muito limitado ou alguém será capaz de acessá-lo?

 

O que ele vai fazer para fechar a lacuna entre os pobres e os ricos?

 

Como as armas perigosas são controladas e impedidas de serem comprometidas? Embora a maioria dessas perguntas foram revelados há 10 anos, ele ainda não parece ter encontrado uma resposta.



 

É difícil dizer exatamente quando essa tecnologia vai ser implementada, e uma razão é que os programas de desenvolvimento militar ou industrial oculto estão sendo conduzidos com um grande segredo fora do conhecimento de um cidadão normal. Não podemos afirmar com exactidão que a nanotecnologia será desenvolvida nos próximos cinco ou dez anos em plena escala. Mas temos de estar preparados para todos os cenários e acompanhar de perto a nanotecnologia e o desenvolvimento.
