borders, interdisciplinarity of nanotechnology – nanowiki #5

admin — Thu, 29 Jan 2009 11:08:15 +0000

In the future,
When Science has reached its plenitude of action,
Chemistry and physics will not be but mere aspects of Molecular Mechanics.
At the nanometric scale the frontiers between biology, chemistry and physics become confused
And between these three
A new discipline is being shaped:
Nanotechnology
A whole generation of scientists, capable of dealing with this new discipline
Has already popping up,
And is being trained now

products, nanotechnology today – nanowiki #6

admin — Thu, 22 Jan 2009 21:08:18 +0000

Products labelled nano today
Are more related to marketing than they are to Science
Nanokeratine, to repair your hair;
Nanohydroxiapatite to repair your teeth;
Nano Silver Poly Technology, desinfectant and deodorant for your fridge
Far from this exaggerated proliferation of nano products
New medicines, materials that shall guarantee efficient energy
Or clean water will be available soon.

the buzz, social impact of nanotechnology – nanowiki #4

admin — Thu, 22 Jan 2009 00:04:12 +0000

Even if scientists often ignore it,
The truth is that the world does not change only because of the introduction of a new technology.
Technology permeates social networks,
so the applications which develop,
are a mixture of both social and technical forces.
If society welcomes a given technology and finds uses for it, this technology shall survive.
When social acceptance does not take place, the new technology dies, no matter how good It may be;
The key to prevent the promises of a better world from dying into oblivion is to enable society to have access to the information.

history, nanoparticles before nanotechnology – nanowiki #2

admin — Tue, 20 Jan 2009 15:09:14 +0000

Nanoparticles existed before nanotechnology.
Every time a volcano roars, carbon nanotubes and fullerenes are formed.
This happens as well when forests,
Or oil, burn.
The thermodegradation of organic matter generates nanostructures
And, indeed, biological processes involve nanoparticles,
Such as magnetosomes, which function as bacterian compasses,
Or ferritin, an iron reserve.
Sometimes humans have taken advantage of nanoparticles without knowing it.
A proof o this are the traces of pigments found in the alveoli of 5000-year-old mummies,
Nanometric titanium dioxide used presumably in tattoos,
Nanoparticles produced spontaneously when mixing oil and natural clay.
Or spontaneously when mixing of aluminosilicates and metallic salts at high temperatures,
AS it happens in the stained-glass windows of churches
Where, for instance, yellow is made of nanoparticles of non-radioactive uranium oxide.
