Graphene takes a step toward renewable fuel

Using the energy from the sun and graphene applied to the surface of cubic silicon carbide, researchers at Linköping University, Sweden, are working to develop a method to convert water and carbon dioxide to the renewable energy of the future. They have now taken an important step toward this goal, reporting a method that makes it possible to produce graphene with several layers in a tightly controlled process. The researchers have also shown that graphene acts as a superconductor in certain conditions. Their results have been published in the scientific journals Carbon and Nano Letters.

 
Carbon, oxygen and hydrogen are the three elements obtained by taking apart molecules of carbon dioxide and water. The same elements are the building blocks of chemical substances used for fuel, such as ethanol and methane. The conversion of carbon dioxide and water to renewable fuel could provide an alternative to fossil fuels and contribute to reducing carbon dioxide emissions into the atmosphere. Jianwu Sun, senior lecturer at Linköping University, is trying to find a way to do just that.


And remember my friend, future events such as these will affect you in the future.

Nanobots propelled through eye tissue

 

12th November 2018

 

For the first time, scientists have developed nano-scale vehicles that can move through dense tissue like the vitreous humour of the eye.

The researchers, led by the "Micro, Nano and Molecular Systems" Lab at the Max-Planck-Institute in Stuttgart, Germany, designed helical-shaped devices resembling tiny corkscrews. Tens of thousands of these tiny machines – smaller than bacteria – were then injected into a pig's eye. A combination of the bots' magnetic material and two layers of a non-stick substance made it possible to guide them, with magnetic fields, in a highly targeted and precise way.

Importantly, this was achieved without damaging the sensitive biological tissue around them. Until now, the viscous consistency of eye tissue had been too challenging for nanomachines like this, but the miniature propellers developed here were able to move relatively unhindered. The swarm also reached the retina in less than 30 minutes, about 10 times faster than letting similar-sized drug particles diffuse through the eye.

^ This might eventually lead to the cure of eye floaters.
