@hersonqfbd @LatEnvChemPSE Chlorine remains more effective, but it produces toxic by-products and loses efficiency with organic matter. The plasmonic Bi₂O₃/BiOBr offer a safer alternative. This was tested under dark conditions, their antibacterial activity can be enhanced under visible light irradiation.

@anarkz @LatEnvChemPSE Regarding the antibacterial activity, ¿do you know whether the effectiveness (antibacterial activity) of these materials may be grater and less toxic compared to chlorine?

@hersonqfbd @LatEnvChemPSE We have tested this heterojunctions againts different type of pollutants such as caffeine, 4-nitophenol, dyes and even anionic compounds. Being multifunctonal materials that can act through different processes. They can potentially be effective against pesticides.

@anarkz @LatEnvChemPSE Dear Ana Laura, I've few questions, ¿caffeine is consider as an emerging contaminant? ¿do you know whether these plasmonic heterojunctions might be effective to remove pesticides, plasticizers, anions, etc.?

@hersonqfbd @LatEnvChemPSE Thank you for your questions. Yes, caffeine is not completely removed with conventional treatment. Its persistence and continuous input from domestic and industrial sources make it a marker of anthropogenic pollution, and it is classified in the group of emerging contaminants

@fer_cardinal @LatinXChem Le agradezco su pregunta e interés, espero haber contestado asertivamente. Sigo al pendiente de cualquier otra duda o comentario. Saludos cordiales

@anarkz @LatinXChem Hola Ana Laura, ¿podrías explicarme porqué se retienen los contaminantes en tus óxidos? En las imágenes de SEM pareciera haber materia orgánica pero no logro comprender de dónde proviene y si están estudiando su rol en la retención del contaminante a degradar. Gracias!

@fer_cardinal @LatinXChem En teoría no deberían tener materia orgánica, debido a que los precursores son nitrato de bismuto y etilenglicol pero se realizan lavados y posteriormente se calcina. Me parece que debe ser del mismo material o tal vez por el recubrimiento de la muestra.

@fer_cardinal @LatinXChem Los contaminantes son retenidos debido a que los oxihalogenuros de bismuto tienen una estructura peculiar con láminas de [bi2o2]2+ intercaladas con capas de átomos del halogeno, y al formar la heterounión con el bi2o3 aumentan el área superficial y le dan mayor porosidad.

@fer_cardinal @LatinXChem Of course, I'm available to discuss my work

@anarkz @LatinXChem Hi Ana Laura, are you available to discuss your poster?

I'm out ✌

@Velazquez_Lab Thank you for asking and providing ideas!

@anarkz Again, great job! ¡Éxito!

@Velazquez_Lab Hello Jesús, we were more interested in the efficiency and reuse of materials. Since the adsorption was almost 100% and the solution for photocatalysis was for the reuse of materials, we did not perform this analysis. However, it is a great suggestion that can complement our work

@anarkz @LatinXChem @LaUASLP Very good job Ana! I'm wondering after the photodegredation process have you characterize the liquid media for degradation products generated...

@LatinXChem It has been a great experience so far, your work gets a lot of visibility and at the same time you can learn from other talented researchers with just one click. It is also inspiring to see the enthusiasm and dedication of the participants.

So, how has been your #LatinXChem experience so far? It has been barely 8 hrs of event, and there is still plenty of time to keep sharing your chemistry with all judges and participants! More than 125,000 interactions have occurred since this morning. Leave here your story.

@Mariana10933561 Thank you for your question. By controlling the amount of dye adsorbed on the surface of the nanotube since a saturation can block active sites for the photocatalytic activity.

@anarkz @LatinXChem @LaUASLP Interesting work! How do you think that you could improve the efficiency of organic compounds removal under visible light?

I just love Akira Miyagawa's combination youtu.be/GEdXagVh-Rs vía @YouTube

All izz well

@montsefg90 ya ponte a escribir :p
