අප්පේ මේක ලියන්න ගිහින් මට එපා උනා. මගෙ යාලුවෙක්ගෙ බ්ලොග් එකක මිනිහ පෝස්ට් එකක් දාල, මට චැට් එකේදි කිව්ව උඹේ අදහසුත් ලියපන් කියල කමෙන්ට් එකක් විදිහට. ඉතින් මම ලිවුව. 

මගෙත් ආසම ක්ෂේත්‍රයක් සම්බන්ධයෙන් තමා ඒ ලිපිය තිබ්බෙ, නිනිති තාක්ෂණය (nano technology). ඉතින් පොඩ්ඩක් වට පිටත් හොයල බලල පොඩි කමෙන්ට් එකක් ලිව්ව. 
මොන පොඩිද? 
මම එච්චර දිගට ලිපි ලියල තියෙන්නෙත් හරි අඩුවෙන්. ලියල ඉවර කරල පෝස්ට් කරල, ඒකෙ දිග දැක්කම හිතුන ඒක ලිපියක් විදිහටම ලිව්ව නම් හොඳයි කියල. 
පොඩ්ඩක් ගිහිල්ලම බලන්නකො.
ඔයාලගෙත් අදහස් දෙන්න ඒ ලිපියට.

Nanotube Made Really Really Light

March 19, 2009 — The lightest material on Earth now packs a powerful punch.

Scientists from Texas and around the world have created a material that, by density, is lighter than air yet, when electrified, instantly and powerfully contracts. Their work is detailed in this week’s issue of the journal Science.

“These artificial muscles are very lightweight and can do wonderful things,” said Ray Baughman, the study author from the University of Texas at Dallas.

While the artificial muscle is unlikely to be used in humans or prosthetic limbs, Baughman says “these sheets of carbon nanotubes … are of great practical interest for LEDs, solar cells, and other applications.”

Aerogels and artificial muscles have been around for decades, but both materials have largely kept to themselves until now. Astronomers have launched spacecraft containing aerogels (so called because 99.8 percent of of the material is air) to gently capture space dust and keep it safe for the return journey to Earth.

Meanwhile, material scientists have created a variety of different artificial muscles, or materials that expand and contract when an electrical charge is applied. Many artificial muscles can only operate within a limited range of temperatures, however, because they contain liquid that will either freeze or evaporate at extreme temperatures.

“The most beautiful thing we can experience is the mysterious. It is the source of all true art and all science. He to whom this emotion is a stranger, who can no longer pause to wonder and stand rapt in awe, is as good as dead: his eyes are closed.”
