An electric field-induced reduction mechanism studied for tuning the band gap of graphene oxide thin films in a two-electrode configuration on a SiO2/Si substrate is presented. During the reduction, temporal changes in the sheet resistance and optical band gap of the film were monitored and the correlation between these parameters in this solid state chemical reaction was established. As the reduction progresses, three different kinds of temporal dependence of electrical characteristics were observed. Further, from spatio-temporal analysis of the reduction of graphene oxide in such a disordered system, an analytical model was developed to describe the time dynamics of the reduction process. This model provides the flexibility for in situ monitoring the band gap of the material in terms of sheet resistance during the reduction, hence allowing device optimization for different applications. It is envisaged that this reduced graphene oxide-based tunable platform may find enormous potential for various electronic and optoelectronic applications.

Recent scientific discoveries reveal that plants are far more intelligent and interconnected than we once imagined. When plants are stressed, diseased, attacked by insects, or facing drought, they send warning signals to neighboring plants through:🌱 Airborne chemical signals🌱 Underground fungal networks (“Wood Wide Web”)🌱 Electrical signaling🌱 Root exudates and microbial interactions.

These hidden communication systems help plants prepare defenses, share nutrients, and survive environmental challenges together. In this podcast, I explore the fascinating science behind plant communication and how emerging technologies like AI, hyperspectral imaging, biosensors, and precision agriculture are helping us decode this invisible language of nature.

🔬 This research could transform:

✔ Early disease detection

✔ Sustainable agriculture

✔ Smart farming systems

✔ Climate-resilient crops

✔ AI-driven plant health monitoring

Plants may be silent to us — but beneath the soil and through the air, an extraordinary biological conversation is constantly taking place.

We dive into the challenges farmers face due to delayed diagnosis, crop loss, and lack of accessible technology—and how AI can bridge this gap. The discussion also covers our innovative approach, including multispectral imaging and scalable solutions that can be integrated with smartphones and drones.

Whether you're a tech enthusiast, researcher, or someone passionate about agriculture, this episode highlights how cutting-edge AI is driving the future of sustainable farming.
