I really enjoyed participating in the 6th World Congress on Advanced Chemistry (Adv. Chemistry 2025). You certainly did a good job, although organizing such international events cannot be an easy task. The presentations that I attended (e.g., M. Sarasija, Sakthi Ferdous, Farshad Akbarnenejad, Sujata V. Bhat, Ruhi Das, Mainak Sinha, Shakuntala Chopade, Rajagopal Ramya, etc.) were interesting to me and I think they showed high quality in both problem setting and problem solving. It certainly broadens my horizons and exposes me to new problems and new approaches to solving them. The presentations I have listened to are certainly thought-provoking, and in that sense the speaker selection was good. I thank you again for the invitation and wish you every success in organizing new scientific congresses.
