Abstract

fetched live from OpenAlex

Ultrathin multilayer films composed of conjugated anionic polyelectrolyte, poly(8-(3-thienyl)octanosulfonate) (P3TOSNa), and positively charged poly(N,N-dimethyl-N-4′-vinylbenzyl-N-2-(decanoyl-N′-methylimino)ethylammonium chloride)-co-(N,N,N-trimethyl-N-4′-vinylbenzylammonium chloride) (Ak-St-H) have been fabricated using the layer-by-layer technique. UV-Vis spectroscopy, atomic force microscopy and spectroscopic ellipsometry were applied for thickness and morphology characterization revealing regular growth and smooth surfaces of the films. An electron accepting molecule (butyl viologen) was then successfully entrapped inside the hydrophobic domains formed by Ak-St-Hvia a solubilization procedure. Photoinduced electron transfer from P3TOSNa polymer to butyl viologen molecules has been observed inside the nanostructured multilayers as confirmed by steady-state fluorescence spectroscopy and time-resolved fluorescence decay measurements. The structure of this water-born film helps to protect the hydrophobic acceptor molecules from aggregation and enables efficient charge separation within the film that is one of the crucial steps in organic photovoltaic systems.

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.
