Nano Technologyyyyyyyyyyy

NANOTECHNOLOGY

  • Nano means small (10^-9 m) but of high potency, and emerging with large applications piercing through all the discipline of knowledge, leading to industrial and technological growth. 
  • Nano-sized structure needs to be magnified over 10 million times before we can easily appreciate its fine detail with the naked eye. 
  • Nanotechnology is already having its impact on products as diverse as novel foods, medical devices, chemical coatings, personal health testing kits, sensors for security systems, water purification units for manned space craft, displays for hand-held computer games, and high-resolution cinema screens. Nanotechnology is expected to have an impact on nearly every industry. 
  • The U.S. National Science Foundation has predicted that the global market for nanotechnologies will reach $1 trillion or more within 20 years.

WHAT IS NANO TECHNOLOGY?

Nanotechnology is a catch-all phrase for materials and devices that operate at the nanoscale. In the metric system of measurement, "Nano" equals a billionth and therefore a nanometer is one-billionth of a meter. 

Nanotechnology is a multidisciplinary science that has its roots in fields such as colloidal science,device physics and supramolecular chemistry.

NANOTECHNOLOGY is a fundamental, enabling technology, allowing us to do new things in almost every conceivable technological discipline. Nano means small (10^-9 m) but of high potency, and emerging with large applications piercing through all the discipline of knowledge, leading to industrial and technological growth.

As the prefix nano indicates extreme smallness. So small, in fact, that a nano-sized structure needs to be magnified over 10 million times before we can easily appreciate its fine detail with the naked eye.
Nanotechnology refers to technologies in which matter is manipulated on the atomic and molecular scale to create novel materials and processes. It is not just the study of the very small; it is the practical application of that knowledge. There are two main routes of entry to the nano-world:

 Its Applications

Nanotechnology and its development is defined by key policy makers, as the development of nanotechnology as the latest mega trend in science and engineering which will bring a wave of radical innovation and perhaps, because of its potentially broad impact, spark new industrial revolution in various application areas1.Areas of applications include immediate impact - drug delivery to treat tumor, cancer (without using radiotherapy & chemotherapy), solar energy, batteries, display technologies, opto-electronic devices, semiconductor devices in nanoelectronics, biosensors, CNT's etc., nanocomposites such as Al2O3 oxides, catalysis, and luminous paints.

Mujhe ab kuch kuch 10,+1+2 ki science ki yaad aa rahi hai or ye padha padha bhi laga but still acha hua ke aapne ise refresh kar diya nahi to mere Dimag ke kissi Kone me Pada hota but fresh hai..


Isi tech ne TATA ko NANO ke lie encourage kiya kya?
SMALLEST CAR [:)] as compared to SAFARI... its BILLONth part [:)]

Hmmm... THhts why one lac car is called NANO.. :-):-):-):-)

All they want is a pleasant experience for us

My experiences with this gloomy world continue. I may sound repetitive and annoying, but there's a reality check for all of us who think that the world is fine as long as the Covid-19 doesn't hit us and our paychecks continue to flow into the banks. 
The store in the picture is amongst the busiest in the area, always remains full and explodes with the people on the Saturdays. A typical brand in a store, let's say a Van Heusen makes about ₹200,000 to ₹220,000 of sales on the weekend. As of today, the store does about ₹10,000 to ₹15,000 of revenues of the same brand, and the footfalls are not even 5 per cent of what they otherwise used to witness. Ironically, a store of this size would have 8-10 salesman with an average basic salary of ₹10,000 to ₹12,000 a month and the balance they earn (~₹5,000-₹7,500) is all linked to the sales of the brand. For them, purchases from the store cover-up for the livelihood, savings and the investments and there are no concept of "work fr…

The new age crisis

I don't know who I should credit or discredit, but last couple of years have been incredible for India and it's people and it is not in a good way. Disappointed to note that the politics has completely taken over us and the ideological differences have reached our houses and personal devices. We are not only fighting amongst us on difference of opinion, but also ensuring that the dissent against a majoritarian view is killed to its core, to the extent that the voice is never raised against any impending thoughts or disagreements we may have. 
I am deeply saddened by the fact that most of us now are actually made to believe that the opinion shared by a larger section of society is deemed right since it has the weight of a the population around, and in case you have reservations to even contest that, you are probably branded as a threat. 
I may have had little problems with CAA or NRC if it wasn't done for the political incentives and the treatment of the people not sharing th…
