It would be a dull month if a new rechargeable battery project didn’t make headlines amid all the excitement surrounding electric cars. This month’s indisputable winner is the lithium-ion battery that replaces cobalt with iron, and-rather surprisingly-works, at least according to the people who came up with the idea.
Multiple sclerosis is an autoimmune, neurodegenerative disease, characterized by distinct disabilities affecting walking, vision, and cognition, to name a few. MS patients differ markedly from each other regarding which disability affects them the most.
“But the big challenge is how do you communicate wirelessly with WiFi using only plastic? That’s something that no one has been able to do before.” To do this, the team used things like 3D-printed springs, gears and switches that could be used to translate motion into antenna-transmitted information.
Graphene. You know may know it as that wonder material that promises to change the way we build roads, craft smartphone screens, kill bacteria or even keep our feet cool. Composed of a one-atom thick sheet of carbon, graphene is thin and highly flexibility, strength and chemical stability. It also conducts electricity 100 times more effectively than copper and moves electrons 140 times faster than silicon (good for fast-charging).
n research described in the journal Nature Photonics, the Turkey-based researchers have developed a 3D laser fabrication technique that deliberately creates the conditions for exploiting these interactions, known as nonlinear feedback mechanisms.
