source:PV magazineGerman researchers developed a lattice arrangement of three different layers of ferroelectric crystals that created a powerful photovoltaic effect.Combining ultra-thin layers of different materials can raise the photovoltaic effect of solar cells by a factor of 1,000, according to researchers at Martin Luther University Halle-Wittenberg (MLU) in Germany.Their findings, published in the journal Science Advances, described a lattice arrangement of three different layers of ferroelectric crystals (in this case, of barium titanate, strontium titanate, and calcium titanate) that c...

source:university of HoustonSuperconductivity, where electrical resistance vanishes, remains a technology that both powers science and mystifies scientists. It charges MRI scanners, enables new drug discovery through advanced spectroscopy machines, and is used to create the kind of powerful magnets that help smash atoms as scientists work to uncover how the universe is made and how it works.  In all of these and more disparate uses, the next-generation machines could have one common connection: the kind of unique wire, or superconducting material, necessary to enable the development ...

source:Ming.comResearchers at the French Geological Survey are looking at ways to extract rare earth elements from mine slag heaps using bacteria found in the subsoil.According to a report by the agency AFP, the process starts by pulverizing mine tailings and dissolving them in liquid.SIGN UP FOR THE BATTERY METALS DIGESTThen, the scientists inject different bacteria depending on the metal they are looking for. They also inject oxygen and nutrients like potassium or nitrogen to feed the microorganisms.These solutions are immediately heated at between 30 and 50 degrees Celsius and agitated by a...
