Công nghệ nano là gì?

Công nghệ nano, đã được tiết lộ bởi Norio Taniguchi tại Đại học Tokyo năm 1974, nhanh chóng nổi lên công nghệ dựa trên nhiều hơn nữa nâng cao độ nhạy và thu hẹp của các công nghệ sẵn có. Trong tương lai, công nghệ này có lẽ sẽ bao gồm cấu trúc máy móc và cơ chế với kích thước nano kích thước của nó, được gọi là phân tửmug (MNT). Công nghệ nano được sử dụng để đo lường một đơn vị đo lường được gọi là nanomet (dạng ngắn nm). Mỗi đo lường có 1 tỷ nm. Mỗi NM là chỉ 3-5 nguyên tử rộng, tức là khoảng 40000 lần nhỏ hơn so với độ dày của một mái tóc con người trung bình.



 

Một khía cạnh của công nghệ nano

 

Máy tính siêu nhỏ (vi khuẩn có kích thước)

 

Siêu máy tính với một kích thước khối đường và hàng tỉ máy tính xách tay điện

 

Nó có thể làm cho kích thước nano máy tính để bàn mô hình có kích thước nhất định có tỷ mạnh hơn so với ngày hôm nay của máy tính.



 

Tiềm năng cao của công nghệ nano được tiết lộ thông qua các định luật của vật lý lượng tử. Ở giai đoạn này, luật vật lý lượng tử được kích hoạt trong kích thước nanovà cho phép các ứng dụng mới trong quang học, điện tử, từ lưu trữ, máy tính, chất xúc tác và các khu vực khác.



 

Công nghệ nano thường được gọi là ngành công nghiệp công nghệ. Bởi vì khi nó được thực hiện, công nghệ Nano sẽ có một vị trí quan trọng trong hầu như tất cả các lĩnh vực và trong mọi lĩnh vực của xã hội. Tốt hơn sản phẩm được thực hiện, kéo dài lâu hơn, sạch hơn, an toàn hơn và thông minh hơn có thể là sử dụng tại nhà, tronggiao tiếp, y học, trong giao thông vận tải, nông nghiệp và trong mọi lĩnh vực của ngành công nghiệp.



 

Hãy tưởng tượng một dụng cụ y tế có thể được tìm thấy mà không lây lan tế bào ung thư bằng cách lưu thông trong cơ thể con người, hoặc nó là nhẹ hơn thép, nhưng nó là một vật liệu là mười lần mạnh hơn nó.



 

Tại sao nên công nghệ nano được sử dụng thận trọng và nhạy cảm? Công nghệ nano, chẳng hạn như điện hoặc máy vi tính, sẽ cung cấp khả năng tốt hơn ở mọi giai đoạn của cuộc sống. Tuy nhiên, như với mọi công nghệ mới, công nghệ nano có hai cách sử dụng, tức là sử dụng thương mại và mạnh mẽ hơn rất nhiều vũ khí và giám sát các công cụ do công nghệ nano trong lĩnh vực quân sự. Đây là lý do tại sao công nghệ nano cũng mang lại một số rủi ro cùng với những lợi ích cho người dân.



 

Một trong hai công nghệ nano, quan trọng là nó không chỉ cung cấp sản phẩm tốt hơn, nhưng cũng nhiều cải tiến công cụ sản xuất. Một máy tính có thể sao chép các tập tin dữ liệu như nhiều như bạn muốn với chi phí rất thấp hoặc miễn phí. Nó có thể làm cho nó dễ dàng và không tốn kém để sao chép các tập tin giống như là một ví dụ cùng một máy tính trong công nghệ nano. Đó là lý do tại sao công nghệ nanođược gọi là cuộc cách mạng công nghiệp tiếp theo đối với nhiều người.



 

Công nghệ Nano sẽ không chỉ cho phép sản xuất nhiều sản phẩm chất lượng cao với chi phí rất thấp, nhưng cũng làm cho nhà máy nano mới với chi phí thấp và tại cùng một tốc độ cao. Lý do tại sao công nghệ Nano được gọi là một công nghệ ngày càng tăng nhanh chóng là khả năng để tái sản xuất dụng cụ sản xuất riêng của mình.



 

Công nghệ nano; Nó cung cấp một chi phí thấp hơn, nhanh hơn và làm sạch hệ thống sản xuất. Dụng cụ sản xuất có thể được sao chép bằng cách nhân, do đó, một vài nano nhà máy sẽ sản xuất hàng tỷ của các nhà máy trong vòng một vài tuần. Đây là một cuộc cách mạng, sáng tạo, mạnh mẽ và công nghệ có tiềm năng rất nguy hiểm hoặc hữu ích.



 

Bao lâu có thể tất cả những phát triển này xảy ra?

 

Ước tính tổng quát là rằng nó có thể giữa 20 và 30 năm hoặc thậm chí sau đó. Nhưng các tiến bộ nhanh chóng trong quang học, in thạch bản nano, cơ khí hóa học vàcông nghệ tạo mẫu 3d có thể rút ngắn thời gian này. Điều quan trọng ở đây là không chỉ làm thế nào một sự cải tiến có thể được thực hiện trong một thời gian ngắn,nhưng cũng sẵn sàng làm thế nào chúng tôi để công nghệ mới này.



 

Có lẽ khi chúng ta tự hỏi mình một số câu hỏi sau đây, chúng tôi có thể tốt hơn cảm nhận nó. Những người sẽ có công nghệ này?

 

Điều này là quá giới hạn hoặc bất cứ ai sẽ có thể truy cập vào nó?

 

Ông sẽ làm gì để đóng khoảng cách giữa người giàu và người nghèo?

 

Làm thế nào là các vũ khí nguy hiểm để được kiểm soát và ngăn ngừa được thỏa hiệp? Mặc dù hầu hết những câu hỏi này đã được tiết lộ cách đây 10 năm, nó vẫn không có vẻ đã tìm thấy một câu trả lời.



 

Thật khó để nói chính xác khi công nghệ này sẽ được thực hiện, và một trong những lý do mà ẩn quân sự hay công nghiệp phát triển chương trình đang được tiến hành với một bí mật tuyệt vời bên ngoài của một công dân bình thường kiến thức. Chúng tôi có thể không chính xác nói rằng công nghệ Nano sẽ được phát triển trong những năm tiếp theo năm hay mười trong quy mô đầy đủ. Nhưng chúng ta phải được chuẩn bị cho tất cả các kịch bản và chặt chẽ theo công nghệ nano và phát triển.
