source:Nature NanotechnologyRare earth elements (REEs), including scandium, yttrium and lanthanides, are strategic resources with unique electric, luminescent and magnetic properties. However, owing to their highly similar physiochemical properties, the identification and separation of all REEs are challenging. Here a Mycobacterium smegmatis porin A nanopore is engineered to contain a nitrilotriacetic acid ligand at its pore constriction. By the further introduction of a secondary ligand Nα,Nα-bis(carboxymethyl)-L-lysine hydrate (ANTA), a dual-ligand sensing strategy was established. A unique ...

source:SMALL CAPSMTM Critical Metals (ASX: MTM) believes its breakthrough in successful recovery of gallium and germanium may help unlock a multibillion-dollar market as governments and industries seek sustainable onshore solutions for securing these critical materials.The company’s new testing achieved recovery of approximately 90% gallium and 80% germanium from semiconductor industry waste using its proprietary FJH technology.The fact that only trace amounts of the two critical metals were found in wash solutions confirms the high capture efficiency within the closed system.Critical minerals...

source:University at BuffaloNanoelectronics deal with extremely small electronic components—transistors, sensors and circuits that can fit on the tip of a needle. This technology powers our everyday lives through devices such as computers, smartphones and medical tools.To improve the efficiency—and power—of these devices, scientists are searching for alternative materials to replace standard silicon-based semiconductors.A University at Buffalo-led study, published in the journal ACS Nano, explores how mixing two-dimensional materials with silicon might achieve this goal. The article suggests a...
