The combination of the narrow free excitonic emission and broad self-trapped emission results in a photoluminescence spectrum which appears white to the human eye. While the ability for perovskites to emit broadband white light is attractive, it is currently not possible to reliably prepare perovskites which exhibit white-light emission at room temperature.

In recent years, the smelting of rare-earth metals, such as neodymium, has also been cited as a small but growing source of CF 4 (Cai et al., 2018; Zhang et al., 2018). Firn air measurements show that the atmospheric abundance of CF 4 has increased rapidly since 1960 ( Trudinger et al., 2016 ) .

2018/9/1Perfluorocarbon greenhouse gases measured in Chinese rare earth metal production. • PFC gases included CF 4, C 2 F 6 and C 3 F 8 and trace levels of c-C 4 F 8, C 5 F 10. CO 2-equivalent emission factors were estimated for three rare earth metals. Emission

Quantifying the mineral carbonation potential of mine

Direct aqueous mineral carbonation is a CO₂ sequestration method that can trap anthropogenic carbon dioxide as a thermodynamically stable carbonate. Ultramafic rocks considered waste at mining operations are targeted as the substrate source for carbonation in this research. Using mining waste to permanently fix CO₂ is a motivating factor for promoting industrial mineral carbonation as a

Critical Rare

Enhanced climate action is needed, but ambitious global wind-power-expansion targets raise concern regarding potential conflicts between the supply and demand of rare-earth elements (REs). Li et al. explore such conflicts across ten global regions through 2050 under four scenarios. They show that RE supply might not be able to meet ambitious wind-power development given the monopolistic

2009/10/1Industrial grade propylene (99.74 mol.%) and industrial grade propane (99.79 mol.%) were used as feed gases. PVDF flat sheet membrane was used as the support of ILM and AgNO 3 solution was used as carrier. Separation experiments were conducted at four.

Nanotechnology for catalysis and solar energy conversion

2020/11/5Earth-abundant transition-metal sulfide-based [] and/or phosphide-based [] electrocatalysts have been developed for evolution of H 2 (g) under acidic conditions. Although these materials are stable for days of operation in the laboratory, long-term stability under operating conditions, including day/night cycling of the electrocatalyst under operating potentials, is not yet demonstrated.

Global discrepancies between top‐down and bottom‐up PFC emission estimates. The bottom‐up reported emissions of CF 4 and C 2 F 6, shown in red, are the sum from the two main sources, the aluminum (AL) and semiconductor (SC) industries, shown in purple and orange, respectively, and account for only two thirds to one half of the measurement‐derived top‐down emissions of these
