Abstract

fetched live from OpenAlex

The need for renewable sources of electrical power continues to grow around the globe, with solar energy at the forefront.This thesis concerns the assembly and testing of a photoelectrochemical cell that utilizes photosynthetic proteins found in plants to capture solar energy and generate electricity.Photosystem II, plastoquinone and thylakoid lipids were extracted from spinach leaves for use in the photocell.An ω-Hydroxythiol SAM on Au electrode was used as the anode to receive electrons from cytochrome C in solution.A platinum on carbon electrode was used as the cathode, with an anion exchange membrane to avoid short circuits forming between the electrodes.The photocell was tested under a variety of conditions and the highest photocurrent produced was 11.5 µA/cm 2 at an applied voltage of 750 mV.2.3 Plastoquinone Extraction . . . . . . . . . . . . . . .

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.
