Abstract

fetched live from OpenAlex

Ordered three-dimensional macroporous SiO2 films were fabricated by colloidal crystal templating. Scanning electron microscope measurements showed that the size of the air sphere replicates that of the initial polystyrene spheres, and that the porous sample exhibits long-range order. Optical measurements show that the macroporous sample exhibits the behavior of a photonic band gap, indicating crystalline order in the sample. Fourier-transform infrared measurements revealed that a strong network of Si–O–Si bonds have been formed throughout the voids of the template before the solidification of the gel. It is proposed that this network hinders the large volume shrinkage during the subsequent heat treatment, and thus high-quality large-scale ordered macroporous films can be obtained.

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.
