Nuclear waste is normally a major environmental headache, but it could soon be a source of clean energy. Scientists have developed a method of turning that waste into batteries using diamond. If you encapsulate short-range radioactive material in a...
Graphite is a new modular shelving solution that harnesses the versatility of the hexagon to adapt to your unique spacial requirements! After all, that honeycomb shape exists naturally for a reason! Easily connected at any of its 6 sides, you can pair them together as high or as long as you need. The configuration possibilities are truly endless so you can add, take away or readapt them to fit any room. Made of special resistant coated aluminum, it’s also designed to last ages so it really can move anywhere you do!
For years, scientists have wondered why Mercury is so dark. It doesn't have as much iron and titanium as the Moon, so it should be brighter. A team at Johns Hopkins' Applied Physics Laboratory finally has the answer, though. Thanks to a spectral anal...
That fast-charging smartphone you just bought has a dirty secret: more likely than not, it's reducing the lifespan or capacity of the battery to get that breakneck speed. Huawei doesn't think you should have to compromise, though. It just showed o...
Consumer technology has improved by leaps and bounds in the past decade alone. But we all know that the same can’t be said of rechargeable batteries. That’s why scientists from Stanford University and their Chinese and Taiwanese colleagues are proud of their invention: a durable, safe and flexible battery that can be charged in just one minute.
The battery has an aluminum anode, a graphite cathode and a liquid electrolyte sealed in a flexible pouch. Aside from its insanely fast charging time, the scientists claim their invention is good for 7,500 charge and discharge cycles. For comparison, the commonly used Lithium-ion battery lasts only up to around 1,000 cycles. Li-ion batteries are also known fire hazards, but this Aluminum-ion battery won’t explode even when punctured. Finally, it’s flexibility should be a boon as gadget makers experiment with different form factors.
But – of course there’s a but – the battery isn’t ready for primetime just yet, mainly because it only outputs half the voltage of Li-ion batteries. The inventors believe that that can be remedied by improving the battery’s cathode. Head to Stanford’s website for more on the invention.
Conductive paint or conductive ink is lets you draw conductive traces, great for simple projects, mockups or even minor electronic repairs. You can easily order these materials from different manufacturers – such as Bare Conductive – but if you want to save money check out Brian McEvoy’s simple guide to making your own conductive paint.
Brian suggests using graphite powder as the conductor and acrylic paint as the medium. In his brief tests, he found that acrylic paint was a better medium compared to Elmer’s glue and Titebond wood glue. The acrylic paint and graphite powder mixture even appeared to have a higher conductivity than Wire Glue, which is a popular conductive paint brand. Head to Instructables to see a brief summary of Brian’s tests. You can also read the unabridged version of his experiment on his blog.
