Powered exoskeleton - An Iron Man on Every Corner

Powered exoskeletons are a wearable mobile machine that is powered by a system of electric motors, pneumatics, levers, hydraulics, or a combination of technologies that allow for limb movement with increased strength and endurance.

For a long time the concept of a true powered Exosuit was confined to the realm of science fiction but in 1960 one was finally created. Co-Developed by the US Armed Forces and General Electric, the Hardiman suit was an exoskeleton that allowed someone to lift a 250lb item like it was 10lbs. Run using hydraulics and electricity, the suit amplified the wearers strength by a factor of 25, meaning that lifting 25 kilograms (55lbs) in the suit was as easy as lifting 1 kilogram (2lbs) without. Here is a video of a US army prototype in action. https://www.youtube.com/watch?v=p2W23ysgWKI

Powered Exosuis have a variety of applications in an assortment of areas, from medical to military and even civilian. These suits could give people without the ability to walk increased independance, and help those working on rehabilitation. in the military sector Exo Suits will decrease the burden of gear a soldier must carry allowing them to do more for longer, but it can also allow them to weild heavier armerments. In the civilian life Firefighters and other rescue workers would be able to be safer and do more in dangerous environments and construction workers could use heavy power tools without the strain curently involved.

There are however limitations and other issues involved with the development and production of exo suits. Power supply is one issue being worked through, current non rechargeable batteries don't have a long enough life and rechargable batteries would require a charger to be brought along, not to mention the time factor of chrging. the skeleton and acuators must also be strong but light otherwise much of the exo suits power would be dedicated to just moving itself.

These problems are being worked on though and technology in these areas is improving seadilly with major breakthroughs every no and then. Lastly here are some pictures of exosuits, frirst you will see a real system then design concept and last a "currently" sci-fi suit concept, I say currently because the suit in the last image is based on a real suit. http://www.livescience.com/38779-elysium-exosuit-science-fiction.html

Graphene - A Super Material We Don't Quite Get Yet

Graphene is an allotrope (meaning "other form") of carbon, where in it exists on an atomic scale as a two dimensional hexagonal lattice. The lattice is built using each atom as a vertex, here is an image showing how it would look on the atomic scale.

Graphene's composition allows for some startling features, three of them are:

• It's the thinnest material known and presently believed to be the strongest.
• It is a single layer of carbon atoms and is both flexible and transparent.
• Graphene is astonishingly conductive for heat and electricity equally.

With features like this Graphene has garnered allot of attention which leads us to the main issue, production. Graphene is made by placing a sheet of copper foil in a furnace containing argon gas. You then place carbon atoms on the copper and cover them with a plastic coating and spun 3000 times a minute. The multi-layered sheet is later broken apart from a combination of chemicals, driving off the copper and most foreign material. The raw graphene is then loaded onto a silicon chip, before being subjected to a blast of gold pellets and plasma. If Graphene lives up to current theories, then it has the potential to be a scientific breakthrough in countless fields. In application Graphene bring us.

• Ultra-fast uploads of terabits a second
• Nearly instantaneous charging
• Cleaning up the tainted water at fukushima
• Improved tennis racquets
• Unbreakable touch screens
• A new generation of headphones
• Graphene super capacitors would eliminate batteries

Graphene could even be used to make a water filter with holes small enough for water to pass through but not salt, even allowing bionic devices to connect directly to a patient’s neurons allowing them to relearn how to use their limbs. 

All of these things still only scratches the surface of what Graphene could potentially do, but there are still problems to overcome. Graphene is currently hard to produce on the scale that would be required to do the things listed above, but scientists are hard at work developing new ways to produce this super material. In 2015 a scientist developed a way to make better quality Graphene in much less time.
