"lighting/display uses rare earth metals such as europium, terbium, yttrium, cerium, gadolinium, consuming 213 billion kWh annually in the US... replaced with stacked MOFs combining 2 types of porous crystals... controlling how components interact... produce same amount of light while consuming far less electricity... simultaneously reduces production costs, ecological impact and energy consumption"
