Nanodots and nanocolumns used to improve superconductors

Nanodots are being used to successfully pin the magnetic field in superconducting wire. This allows for more stable current flow and better retention of performance over longer wire. The performance necessary for many applications appears possible using this technique There are still many hurdles but this appears to be a path to success. The performance …

Editorial: No Fermi Paradox: Hey no one visited my anthill

The Fermi paradox is if the universe contains many technologically advanced civilizations, combined with our lack of observational evidence to support that view, seems to be inconsistent. Either this assumption is incorrect (and technologically advanced intelligent life is much rarer than we believe), our current observations are incomplete (and we simply have not detected them …

Other tech: Regenerative medicine, artificial organs and emergency medicine developments

Researchers have achieved success in reversing paralysis in rats using hydrogels which had stem cells mixed in and the material placed into the space of the spinal cord gap. Hydrogels resemble the soft tissue that surrounds a human spinal cord as it develops in the womb. The researchers estimate gel-based spinal cord repair clinical trials …

Nanotube and shape memory artificial muscle 100 times capability of skeletal muscle

The Korean team’s continuously shorted fuel-cell muscle incorporated a shape-memory wire coated with nanoparticles of platinum catalyst. This type of muscle converted the chemical energy of the fuel into thermal energy, which caused actuation. The fuel-cell muscle’s work capability was 100 times that of skeletal muscle They also created a cantilever-based nanotube fuel-cell muscle, the …

Nanofluids: nanoparticles suspended in fluid: 400% better as coolant

By suspending nanoparticles in water or other liquids, Professor Richard Williams and Dr Yulong Ding have created ‘nanofluids’ which can transfer heat up to 400% faster than other liquids. In a central heating system, nanofluids could increase efficiency without the need to use a more powerful pump, so saving energy and providing major environmental benefits. …

Other tech: Neurons and silicon transistors interfaced

NACHIP’s core achievement was to develop a working interface between the living tissue of individual neurons and the inorganic compounds of silicon chips. With the help of German microchip company Infineon, NACHIP placed 16,384 transistors and hundreds of capacitors on a chip just 1mm squared in size. The group had to find appropriate materials and …

Other tech: Data transmitted at a record 2.56 terabits per second

German and Japanese scientists recently collaborated to transmit a data signal at 2.56 terabits per second over a 160-kilometer link (equivalent to 2,560,000,000,000 bits per second or the contents of 60 DVDs) the researchers bettered the old record of 1.28 terabits per second held by a Japanese group. By comparison, the fastest high-speed links currently …
