Gold nano-coating works like an anti-fog heating element for glasses

While anti-fog sprays work to a certain extent, warming a glass surface is a better way of keeping it fog-free. A new coating material is designed to do so, and it utilizes light-absorbing gold nanoparticles instead of electricity.Continue ReadingCateg… Continue reading Gold nano-coating works like an anti-fog heating element for glasses

Infrared implant between skin and skull helps kill brain cancer

Brain cancer is one of the most insidious forms of the disease, but researchers at Stanford have now developed a wireless device that could help improve survival times. When implanted between the skin and skull, the remotely activated device heats up g… Continue reading Infrared implant between skin and skull helps kill brain cancer

Gold nanoclusters make old antibiotics effective against superbugs again

Drug resistance is an increasing problem in bacterial infections, but a new study may have uncovered a way to reinvigorate old antibiotics. Scientists have wrapped gold nanoparticles in molecules that seek out bacteria and disrupt their cell membranes,… Continue reading Gold nanoclusters make old antibiotics effective against superbugs again

Washable conductive clothing monitors muscle activity

Currently, if you wish to track the electrical activity of someone’s muscles, you have stick electrodes onto their skin. An experimental new technology, however, simply utilizes conductive fabric that’s incorporated into washable pieces of clothing.Con… Continue reading Washable conductive clothing monitors muscle activity

Flash-heating efficiently recycles precious metals from e-waste

Electronic waste (or e-waste) is not only a major pollutant in landfill, but huge amounts of useful resources are being thrown away. Engineers at Rice University have now shown that precious metals and rare earth minerals can be recovered by flash-heat… Continue reading Flash-heating efficiently recycles precious metals from e-waste

Volcanic brine mines could be green sources of copper, gold and lithium

One hurdle standing in the way of a transition to renewable energy is the increased need for mining that these technologies bring. Now, Oxford scientists are investigating a new way to mine valuable metals trapped in hot brines beneath volcanoes – with… Continue reading Volcanic brine mines could be green sources of copper, gold and lithium
