Stunning discovery may change US military forever

In a huge breakthrough, scientists have developed a graphene-based material that could stop bullets and be used for armor.

Scientists may have just come up with a way to save an incredible amount of people thanks to an incredible technology known as graphene sheets. Researchers think they’ve found a way to make a bulletproof graphene that would allow them to create lightweight protective vests for police officers and soldiers.
This huge breakthrough was made possible by using two graphene layers to create this new materials, which is soft and light but incredibly strong, able to stop a speeding bullet or other objects. The material is as thin as aluminum foil, but once put under pressure it becomes very hard and rigid, so it could be adapted for a number of uses.....................

Graphene Could Double Electricity Generated From Solar | IFLScience
The amount of sunlight that hits the Earth every 40 minutes is enough to meet global energy demands for an entire year. The trick, of course, is harnessing it and converting it into useful electricity. A new study has revealed that tweaking graphene allows it to generate two electrons for every photon of light it receives.

Could graphene ripples be tapped into as a clean, limitless energy ...
Nov 23, 2017 - As if graphene wasn't versatile enough already, researchers at the University of Arkansas have now found a way for the two-dimensional material to be used as a source of clean and potentially unlimited energy. By tapping into the random fluctuations of the carbon atoms that make ...

Graphene - A simple introduction - Explain that Stuff
Jan 30, 2017 - Graphene was first discovered in 2004, but what's caused such excitement is that its properties (the way it behaves as a material) are remarkable and exciting. Briefly, it's super-strong and stiff, amazingly thin, almost completely transparent, extremely light, and an amazing conductor ofelectricity and heat.

Graphene-coated solar panels could create electricity from raindrops ...
Apr 11, 2016 - Scientists in China are developing a solar panel that could be used to generate powerfrom an unlikely source—rain. Graphene, which consists of just a single layer of carbon atoms arranged in a honeycomb structure, was discovered a decade ago and has been put to several scientific uses. Previous work ...

Publications – Graphenea
What makes graphene so special is its sp2 hybridisation and very thin atomic thickness (of 0.345Nm). These properties are what enable graphene to break so many records in terms of strength, electricityand heat conduction (as well as many others). Now, let's explore just what makes graphene so special, what are its ...

Flowing salt water over graphene generates electricity | Ars Technica
Apr 14, 2014 - Hydroelectricity is one of the oldest techniques for generating electrical power, with over 150 countries using it as a source for renewable energy. Hydroelectric generators only work efficiently at large scales, though—scales large enough to interrupt river flow and possibly harm local ecosystems.
