source:theconversationResearchers in the US have finally fulfilled an objective that was set decades ago: the achievement of “ignition” – getting more energy out than you put in – using nuclear fusion.The scientists at the Lawrence Livermore National Laboratory’s National Ignition Facility (NIF), where the experiment took place, are no doubt both excited and relieved to finally fulfil the promise implied by the name of their facility. But how excited should the rest of us be? What does this really mean for the possibility of creating effectively unlimited amounts of clean energy, and what else...

source:euronewsYour electronics could soon be powered by an ultra cheap sea salt battery.Researchers have built a new cheap battery with four times the energy storage capacity of lithium.Constructed from sodium-sulphur - a type of molten salt that can be processed from sea water - the battery is low-cost and more environmentally friendly than existing options. It could be a ‘breakthrough’ for renewable energy, according to lead researcher Dr Shenlong Zhao, from the University of Sydney.“Our sodium battery has the potential to dramatically reduce costs while providing four times as much st...

source:investorintelIn the last 5 years since I last wrote for InvestorIntel, as they say, there’s been a lot of water under the bridge. But 5 years ago, could you have predicted the actual water flow? Could you have had a target? Where is Macca’s head space at? Well as usual I’ll get there. So the last 5 years have been part of my “eco-retreat” project taking our property to almost pristine Australian forest, complete with all the native wildlife that goes with that. Achieved – yes! To plan – pretty much. Took longer but a few un-planned for health issues slowed me down, but overall happy. So...

source:natureAbstractLanthanoid-doped Gallium Nitride (GaN) integrated into nanophotonic technologies is a promising candidate for room-temperature quantum photon sources for quantum technology applications. We manufactured praseodymium (Pr)-doped GaN nanopillars of varying size, and showed significantly enhanced room-temperature photon extraction efficiency compared to unstructured Pr-doped GaN. Implanted Pr ions in GaN show two main emission peaks at 650.3 nm and 651.8 nm which are attributed to 3P0-3F2 transition in the 4f-shell. The maximum observed enhancement ratio was 23.5 for 200 nm di...
