Reducing stranded assets through early action in the Indian power sector

Environmental Research Letters, 2020
Cost-effective achievement of the Paris Agreement’s long-term goals requires the unanimous phase-out of coal power generation by mid-century. However, continued investments in coal power plants will make this transition difficult.

Sequential Reduction of Chromite Pellets Using Hydrogen and Silicon Carbide for Carbon Emission Abatement During Ferrochrome Production

steel research international, EarlyView.
H2 prereduction selectively metallizes Fe in UG2 chromite pellets at 1100°C, while silicon carbide becomes active at 1300°C to convert remaining Cr2O3 to carbides and promote Cr metallization. By separating the roles of H2 and SiC, the sequential route reaches up to 65.7% Cr metallization and suppresses in‐furnace CO generation by ≈75% versus ...

Timing the Sacred: A Multi‐Step Chronological Framework for the Llullaillaco Inca Burial

Archaeometry, EarlyView.
ABSTRACT Absolute radiocarbon dating offers high precision, but its application to historical contexts, such as the Inca civilization, requires a rigorous methodological approach. This research examines methods to enhance chronological accuracy through a case study of artifacts from the Llullaillaco Capacocha sacrifice.
