[DEFN-TSXV, DFMTF-OTCQB, 35D-FSE] Executive Chairman Guy de Selliers says the company is poised to make significant progress in developing its “world-class” Wicheeda rare-earths deposit in British Columbia.Whiceeda is an advanced mineral project with a measured resource of 6.4 million tonnes, averaging 2.86% total rare earth oxides (TRE0), including an indicated resource of 27.8 million tonnes averaging 1.84% TREO, and an inferred resource of 11.1 million tonnes, averaging 1.02% TREO. The project is located 80 kilometres northeast of the City of Prince...

source:Indian Institute of ScienceIn a new study published in Nature, researchers at the Indian Institute of Science (IISc) and collaborators show that the efficacy of a commonly used piezoelectric ceramic material can be dramatically increased just by reducing its thickness and by preventing atomic defects inadvertently formed during manufacturing.Piezoelectric materials deform (stretch or contract) when an electric field is applied, making them suitable for wide-ranging applications, from ultrasound imaging in hospitals to actuators in guided missiles. Single crystals of some synthetic piezo...

source: Macquarie UniversityTo transition to a green economy, we require more critical metals such as copper, rare earth elements and cobalt than are currently available. Therefore, we need to find new resources formed in different ways in areas that have not yet been explored.Research led by Dr. Chunfei Chen's post-doctoral research in the Earth Evolution research group at Macquarie University, published on 8 January 2025 in Nature, explains the probable locations and mechanisms of accumulations of critical metals at the margins of old cores of continents."These cores are the thickes...

source:Daegu Gyeongbuk Institute of Science and TechnologyA research team has successfully developed a new technology to control doping at the nucleus (seed) phase to increase the performance of semiconductor nanocrystals. The study uncovered how the doping process and location differ depending on the type of doping element (dopant). The developed technology is expected to be widely utilized in advanced electronic devices, such as displays and transistors.With the rapid development of advanced technologies in recent years, such as displays and transistors, interest in technologies that can pre...
