Abstract

fetched live from OpenAlex

Selective dissolution, also known as de-alloying, is a corrosion process by which an element of a binary alloy is selectively removed using an electrochemically well controlled process. The product of this process represents a porous material with a sponge like aspect that is created by randomly interconnected ligaments. In the present research were studied two different compositions of AgAu alloys: Ag77Au23 and Ag72Au28. Both materials were de-alloyed by means of electrochemical dissolution. The measured Young's modulus indicated very low values, around 100 MPa. This is the lowest value measured for this type of nanoporous material up to now.Compared with other measured values from the literature (7 GPa to 12 GPa [29]) for the same type of nanoporous material fabricated in similar conditions our measured values were found extremely small.

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.

Full frame distilled prediction

Teacher imitation

Not 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.
