Do you know about NASA - CHIPS Mission. I bet you dont...

CHIPS (Cosmic Hot Interstellar Plasma Spectrometer) is an American (NASA) astrophysics spacecraft that was launched by a Delta 2 rocket from Vandenberg AFB at 00:45 UT on 13 January 2003. The 60 kg, triaxially-stabilized spacecraft has a spectrograph covering the 9-26 nm wavelength band at a resolution of 0.1 nm, scanning the entire sky in chunks of 5 degree x 27 degree segments during each orbit. The targets are the hot and diffuse nebulae at about a million degrees temperature. The band covers several strong emission lines. Launch Date:   2003-01 13     Launch Vehicle:  Delta II Launch Site:   Vandenberg AFB, United States Mass:   60 kg  CHIPS carried out an all-sky survey of the diffuse background at wavelengths from  90  to 260 Å at a spectral resolution between about λ / 150 and λ / 40, and a spatial resolution of 5 to 15 degrees. CHIPS detected diffuse emission near 170 Å, but this turned out to be associated with the earth’s thin outer atmosphere or its int

Graphene : The Future of Tomorrow

Graphene, the most elusive material today has opened a new arena of possibilities that could drive us towards our never thought future in a much different way.

WHY IS IT SO IMPORTANT ?
  • Graphene has a theoretical specific surface area (SSA) of 2630 m2/g. This is much larger than that reported to date for carbon black (typically smaller than 900 m2/g) or for carbon nanotubes (CNTs), from ≈100 to 1000 m2/g and is similar to activated carbon.
  • Graphene is a transparent and flexible conductor that holds promise for various material/device applications, including solar cells, light-emitting diodes (LED), touch panels and smart windows or phones. Graphene has also been used in other fundamental electronic devices, such as capacitors and Field Effect Transistors (FETs), in which it can act as an atomically thin channel. In the same framework, fluorine-doped graphene has shown to have insulating properties and it can be used as a passivation layer in graphene FETs, leading to a substantial increase in carrier mobility.


Being able to create supercapacitors out of graphene will possibly be the largest step in electronic engineering in a very long time. While the development of electronic components has been progressing at a very high rate over the last 20 years, power storage solutions such as batteries and capacitors have been the primary limiting factor due to size, power capacity and efficiency (most types of batteries are very inefficient, and capacitors are even less so). For example, with the development of currently available lithium-ion batteries, it is difficult to create a balance between energy density and power density; in this situation, it is essentially about compromising one for the other.

In initial tests carried out, laser-scribed graphene (LSG) supercapacitors (with graphene being the most electronically conductive material known, at 1738 siemens per meter (compared to 100 SI/m for activated carbon)), were shown to offer power density comparable to that of high-power lithium-ion batteries that are in use today. Not only that, but also LSG supercapacitors are highly flexible, light, quick to charge, thin and as previously mentioned, comparably very inexpensive to produce.


How can we call it as the Future of Tomorrow ?

Well this simple yet most profound discovery made by a physics professor and his PhD student in a laboratory in Manchester, using a piece of graphite and some Scotch tape has completely revolutionised the way we look at potential limits of our abilities as scientists, engineers and inventors. It has opened the possibilities of making lightning fast computers and electronic devices. Once if we get to know its full potential, we might be able to unlock new secrets which we make us s the superhumans.
