Large-area preparation of flexible carbon nanofilms with synergistically enhanced transmittance and conductivity source:physLarge-area flexible transparent conductive films (TCFs) are urgently needed for future electronics, optoelectronics, energy devices and other fields. Indium tin oxide (ITO) TCF, which is widely used in modern technology, faces difficulties in meeting the needs of scientific and technological development (especially a new generation of flexible electronic devices) because indium is a non-renewable resource and expensive, and ITO is inherently brittle.Currently, carbon...

source:miningResearch led by the University of Utah has documented elevated concentrations of rare earth elements, or REEs, in active mines rimming the Uinta coal belt of Colorado and Utah.The work, published in the journal Frontiers in Earth Science, explains that these mines could see a secondary resource stream in the form of metals used in renewable energy and numerous other high-tech applications.“The model is if you’re already moving rock, could you move a little more rock for resources towards energy transition?,” study co-author Lauren Birgenheier said in a media statement. “In those a...

source:Oak Ridge National LaboratoryScientists have uncovered the properties of a rare earth element that was first discovered 80 years ago at the very same laboratory, opening a new pathway for the exploration of elements critical in modern technology, from medicine to space travel.Promethium was discovered in 1945 at Clinton Laboratories, now the Department of Energy's Oak Ridge National Laboratory, and continues to be produced at ORNL in minute quantities. Some of its properties have remained elusive despite the rare earth element's use in medical studies and long-lived nuclear batt...
