High-Density COH<i><sub>x</sub></i> Network Glass
Bibliographic record
Abstract
Polymeric solids made of simple “organic” hydrocarbons are primarily in one-dimensional (1D) chains and less frequently in 2D polymers like graphene. Research efforts aimed at development of 3D hydrocarbon polymers have resulted in low-density covalent–organic and metal–organic frameworks. However, the synthesis of dense hydrocarbon networks with high chemical energy density has not been achieved. Here, we present evidences of a new high-density (∼3.23 g/cm3), predominantly single-bonded transparent COHx (x < 2) network glass, synthesized by chemical reactions in dense solid mixtures of CO and H2 at 9–30 GPa and recovered at ambient conditions with long-term stability. This material constitutes a first made, dense 3D hydrocarbon polymer at a class of diamond and cubic-BN, which can be used for chemical energy storage and novel electro-optical materials.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
