source:thewestOngoing exploration across a pair of prospects at Asra Minerals’ flagship Mt Stirling Project in WA has returned a clutch of notable rare earths and critical mineral results. The company has so far plunged over 1300 holes for 16,516m at the site and has now confirmed the widespread presence of rare earths, nickel, cobalt and scandium mineralisation in a shallow blanket of weathered rocks.Recent drilling at Asra’s Wishbone prospect returned a string of total rare earth yttrium oxides, or “TREYO” results grading over 200 parts per million within a 1.3 x .5km wide corridor.Initial a...

Study proves efficacy of nanomaterial-based disinfectant developed to combat COVID-19 spread source:phys.orgA team of UCF researchers have proven the efficacy of a nanomaterial-based disinfectant they developed to combat the spread of the COVID-19 virus. Through their experiments, they found that the disinfectant was able to kill several serious viruses including SARS and Zika. The results of their findings were recently published in ACS Applied Materials and Interfaces.'It is always a delight to have our research work featured in a reputed journal,' said Udit Kumar, a doctoral st...

Post-measurement compressed calibration for ICP-MS-based metal quantification in mine residues bioleaching source:natureAbstractBioleaching is an actual economical alternative to treat residues, which allows, depending on the chosen strategy, two possible outcomes: (1) a leachate enriched with target metals, or (2) a residue enriched in target metals through the leaching of interfering components (IC). This work aimed to study the metals released by bioprocessing the Panasqueira mine tailings, as a strategy to increase critical metals' relative concentration in residues. Biostimulatio...

source:cnetFrom weddings to Independence Day celebrations, sparklers are a hot choice for bringing some light, fire and fun to a party. A team of researchers experimented with new recipes for sparklers and came up with some wild color-changing and branching pyrotechnic effects.There are already sparklers on the market that change colors as they burn down, but these new formulations change mid-spark. The secret is in the materials that burn. Combining the rare-earth metal ytterbium with copper created a shower of long sparks that turned from gold to green. The American Chemical Society (AC...
