Perfection is overrated: Flawed graphene sheets may lead to better fuel cells

crownethersf

A rather surprising study found that graphene’s imperfections can actually be used to improve fuel cell efficiency. Researchers from Northwestern University worked together with scientists of five other institutes to show that defective graphene actually works as the world’s thinnest proton channel—only one atom thick.

3D printing: the history and the future

8215690357_6c764305a6_n

The technology of 3D printing has reached an interesting point in its trajectory. It’s been around for years, lots of people know it exists and it has even reached the high street. However, there’s still something of a gap between its promise and the reality, and it looks like the general public are yet to be convinced. So perhaps now is a good time to take stock of 3D printing: its history and its future.

New beehive extracts honey without disturbing the bees

honey-1

Beekeeping can be quite difficult, but thanks to a new invention – it just got a lot easier. Stuart and Cedar Anderson, a father-and-son developed a tap system which allows the honey to be harvested without actually disturbing the bees. The Flow Hive not only reduces bee stress, but also eliminates one of the most laborious and unpleasant activities connected to…

The Mantis Shrimp has some of the most amazing eyes in the animal kingdom. Researchers have shown that among others, it is able to detect a variety of cancers and visualize brain activity. Now, scientists from Queensland University have studied how the mantis shrimp’s eyes are superbly tuned to detect polarized light, and literally see cancers. Professor Justin Marshall, from the Queensland Brain…

Scientists develop camouflage device inspired from octopus skin

opto-cover-790x262

A mixed team of scientists and engineers developed a thin, flexible 4-layer material that autonomously camouflages itself to the surroundings, constantly evaluating the optical surroundings and automatically adapting to them – much like a chameleon or an octopus does. It’s the first system of its kind; it takes it just 1-2 seconds mimic the characteristics of the surroundings, just like the chameleon….

Graphene rubber bands: flexible, low-cost body sensors

G-bands-body-monitors

Graphene, the wonder material shows its potential once again: now, using graphene and rubber bands, engineers have created a flexible sensor which has significant medical value and can be made cheaply. You really should know about graphene by now – we’ve written dozens of articles about it just in the past couple of years; but if you don’t, here’s your…

Depending on where you live, bike stealing can be a distant threat or a constant worry, but in most parts of the world, people would rather be safe than sorry, tying their bikes to trees or fences or whatever they could find. But that may very well change in the near future: three engineers from Chile have developed a bike…

UK project brings us closer to Mach5 air travel

1408635705844

If you thought research in airplanes only applies to the military, you’re wrong. While most of the money spent for airplane research does go to the military, a smaller chunk of it goes to space research, and another part goes to private air travel. Now, a company from the UK has almost developed an engine that would make the legendary…

Canada’s most famous (and from what I can find, only) beer-cooler turned hitchhiking robot has finally completed its 6,000-kilometre journey across Canada, blazing rides from Halifax reaching Victoria late Saturday; and he did it with style: I’m on a boat. Well, a ferry to be exact. Victoria, I’m on my way. #hitchBOT @BCFerries pic.twitter.com/SPewf9rIq1 — hitchBOT (@hitchBOT) August 16, 2014 In case…
