Automated electrode array for in-channel electrochemical detection
Bibliographic record
Abstract
This work presents a low-cost microfluidic device with sensitive, in-channel electrochemical detection capabilities in microfluidic device. This is accomplished using in-channel gold microelectrodes. The detection unit is composed of (i) the working electrodes (WE) with (ii) a common pseudo-reference electrode (RE) in gold and (iii) a counter electrode (CE) made with indium tin oxide (ITO) on a glass substrate. A redox solution ferrocyanide/ferricyanide was flowed through the microfluidic channel in order to test sensing capabilities using cyclic voltammetry (CV). This solution was confined by an electrochemically inactive solution (ultra-pure water) in the same channel. The position of the interface between the redox solution and the confinement solution could be changed via the ratio between their volumetric flow rates. Cyclic voltammetry allowed the detection of electro active species with reduction current of 150 nA.
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 machine prediction
Teacher imitationNot 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.
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 source (direct Gemma or distilled Codex), not a consensus.
