Abstract

fetched live from OpenAlex

Aqueous graphene inks were obtained by liquid-phase exfoliation of graphite and bonded to biodegradable polymers. Consequently, green and eco-friendly graphene inks are proposed that are free of VOCs and harmful organic compounds. Three graphene inks indicated as GGe, GTr, and GTw were prepared with corresponding optimized biopolymer concentrations of 0.1 mg.mL−1of gelatin, 1 mg.mL−1triton X-100, and 1.5 mg.mL−1tween-20. The flake diameter distribution for the graphene inks ranged from 100 nm to 800 nm as measured by dynamic light scattering (DLS). GTr is made of smaller flake diameters followed by GTw and GGe has the largest flakes. Graphene films were printed using aerosol jet technique with a 500 nm thickness and their sheet resistance (sR) was of$2.6\ \mathrm{k}\Omega/\square$for GTr,$5\ \mathrm{k}\Omega/\square$for GTw, and$14\ \mathrm{k}\Omega/\square$for GGe. The low sheet resistance for GTr was assigned to better ink wettability and adhesion on top PET substrates. These electrical resistances are suitable for the fabrication of green chemiresistive flexible sensors.

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.
