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 …

Other tech: Wind turbine basics

Here is some information about optimal wind turbine power generation. Wind Turbines are limited by what is called the Betz law. Simply put, if you capture 100% of the energy available in the wind, you stop the wind. The Betz limit says that essentially, if you capture 59.6% of the energy in the wind, that …

other tech: Electricity from waves and motion

Electricity generated from waves and motion by using low friction ferrofluid. Ferrofluid over a magnet is 40 times slippier than ice. Jeffrey Cheung of Rockwell Scientific in Los Angeles has generated at least 0.3 watts from a ocean buoy even in very calm waters. One hope is that in three years this could be scaled …

Other tech: Gravity field generation in Europe

If confirmed, a gravitomagnetic field of measurable magnitude (one thousands of the earths gravity) was produced for the first time in a laboratory environment. These results may open up a new experimental window on testing general relativity and its consequences using coherent matter. The field was generated by a rapidly spinning superconducting disc.The full paper …

Nanotube Electronics: IBM makes full transistor circuit with a carbon nanotube

A functioning processor on a carbon nanotube has been created by IBM scientists, offering the possibility of terahertz processors in hybrid nanotube silicon devices in 5-10 years. The IBM researchers created a type of logic device called a ring oscillator. It consisted of 12 bi-metal field effect transistors laid along the 18 micrometre length of …

Future of military Technology discussion

Author and Pentagon advisor John Arquilla believes that today’s big-weapon systems are wrong for modern battle and for future battle Some of the main points: how many British submarines did it take to pen up the entire Argentine navy? Two. The Exocet missile proved the slow-moving capital ship’s vulnerability. Today, the Chinese aren’t developing aircraft …
