source:TOHOKU UNIVERSITYResearchers at Tohoku University have successfully increased the capacity, lifetime durability, and cost-effectiveness of a capacitor in their pursuit of a more power-efficient future. A capacitor is a device used as part of a circuit that can store and release energy, just like a battery. What makes a capacitor different from a battery is that it takes much less time to charge. For example, your cellphone battery will power your phone instantly, but charging that battery back up to 100% when it dies is far from instantaneous.While this makes capacitors sound like the s...

source:MININGCritical Metals Corp. (Nasdaq: CRML), coming off its acquisition of a controlling stake in the Tanbreez rare earth project in Greenland, has kicked off diamond drilling program with a view of upgrading the resource and the potential mine throughput.The Tanbreez deposit currently hosts 28.2 million tonnes of total rare earth oxides (TREO) contained in 4.7 billion tonnes of material, of which more than 25% are heavy rare earth elements (HREE), according to internal company estimates. This makes Tanbreez the largest known REE project in the world.Sign Up for the Africa, Europe & ...

source:SMALL CAPS has scored a “hat trick” with all three completed drill holes at its 100%-owned Havilah project in NSW intersecting significant sulphide mineralisation.Diamond drill hole HVD003, which tested an extensive Hazelbrook copper soil and rock chip anomaly, intersected patches of semi-massive copper and zinc sulphides as well as vein and disseminated sulphides across an 80-metre zone.The third hole of the program tested an extensive north-east to south-west trending copper-zinc soil anomaly that had been previously defined with rock chip values of over 1% copper.Aligned mineral...

source:phys.orgHealthy lighting technology is receiving increasingly widespread attention. Traditional solid-state lighting sources utilize photoluminescence down conversion technology to realize ideal white emission. Specifically, yellow phosphors are excited by blue LEDs, or three-primary-color phosphors are excited by ultraviolet LEDs.This strategy inevitably incorporates intense blue-violet components within the emission, which are harmful to the human body. Moreover, discrepant degradation rates of the emitters lead to instability of the emission spectra, and rare-earth metals (e.g., Y, C...
