Abstract

fetched live from OpenAlex

Following power generation, cement stands as the second-largest industrial source of anthropogenic greenhouse gas emissions. However, in this invention a new molten salt chemistry now enables solar thermal energy to drive to calcium oxide production, completely eliminating carbon dioxide emissions during cement production. This achievement is realized through a one-pot electrochemical synthesis method with both environmental benefits and cost efficiency. Two modes of the invention include a direct mode in which limestone is electrochemically converted to lime without CO 2 emission, and the indirect mode in which the CO 2 from the conventional production of lime is electrochemically converted to carbon. This invention is currently undergoing scale-up with support of the Emissions Reduction Alberta Grant IT0162473. We are looking for collaborators, joint-venturers and investors.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
