Our work on Bio-based PEDOT serving as efficient hole-transport layer is just out in Nanoscale. The study is result of a fruitful collaboration between GCNN and the Instituto de Microelectrónica de Sevilla (IMSE-CNM-CSIC). The publication is freely accessable at https://doi.org/10.1039/d5nr04688b. Enjoy reading.

Developing sustainable hole-transport materials that can match the performance of conventional poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) remains a key challenge for environmentally compatible optoelectronic devices. In this work, nanocrystalline cellulose (NCC) is demonstrat...

Just out: our latest work on eco-friendly aqueous inks of carbon nanomaterials with nanostructured biopolymers and its application in electrochemical monitoring of pharmaceutical wastewater, validated at pilot scale. The work is the result of a fruitful collaboration between GCNN, University of Chile, and Metropolitan Tecnological University at Santigo de Chile. The study is entitled: "Electrochemical detection of sulfamethoxazole in
water matrices using green nanomaterials: pilotscale
validation in a solar photo-Fenton process" and is published in Environmental Science: Nano, freely available under:

This work presents an electrochemical sensor designed as a process-monitoring tool for tracking sulfamethoxazole (SMX) during advanced oxidation processes (AOPs) under pilot-scale, realistic wastewater conditions. The sensor is based on eco-friendly aqueous inks combining carbon nanomaterials with n...
