On 27 February, HerAqua consortium members convened online for the second M.ERA-NET meeting to assess initial progress and coordinate forthcoming activities across the work packages. The meeting was attended by Victor Diculescu, Rafael Buoro, Diego F. Pozo Ayuso, and Katarzyna Siuzdak.

The team led by Victor Diculescu reported the establishment of a calibrated 3D-printing workflow, the definition of microchannel design tolerances, and the application of numerical simulations to identify electrode geometries ensuring stable hydrodynamic and electrochemical performance.

Within WP2, Rafael Buoro presented sustainable synthesis routes for graphene quantum dots (GQDs) prepared from citric acid and glucose using natural deep eutectic solvents. When incorporated into conductive matrices, these GQDs demonstrated improved electroactive surface area and charge-transfer efficiency.

At IMP PAN, ongoing efforts focus on the optimization of fluoride-free electrochemical synthesis of MXenes from MAX phases. Although full delamination into separate layers remains challenging, progress continues under the supervision of Katarzyna Siuzdak.

Moving forward, partners will refine GQD-based electrode formulations, continue MXene ink development under the guidance of Diego F. Pozo Ayuso, advance microfluidic device design, and maintain coordinated dissemination through the project website, LinkedIn, and upcoming conferences.
