Mejora del acceso a la detección de la insuficiencia cardíaca con saliva
American Chemical Society (ACS)

En el calor abrasador del verano, cualquier persona que pase tiempo afuera podría beneficiarse de un tejido refrigerante. Pero ahora, los investigadores han innovado con un revestimiento de microescala a base de tiza que enfría el aire debajo del tejido tratado hasta 13 grados Celsius. Presentarán sus resultados en la ACS Fall 2024.

Expansión con luz del implante cardíaco de un niño
American Chemical Society (ACS)

Los niños que nacen con ciertos defectos cardíacos se someten a un implante de shunt para mejorar el flujo sanguíneo. El shunt debe cambiarse a medida que el cuerpo crece. Los investigadores informan que un nuevo shunt expandible que reacciona a la luz podría reducir el número de cirugías a las que se someten estos niños. Presentarán sus resultados en la ACS Fall 2024.

Se acumulan las pruebas de libros venenosos que contienen tintes tóxicos
American Chemical Society (ACS)

Algunos libros de la época victoriana fueron teñidos con pigmentos tóxicos. Las últimas investigaciones sobre estos “libros venenosos” utilizaron una técnica no aplicada previamente a los libros para evaluar una colección universitaria, y los investigadores descubrieron que algunos volúmenes tenían posiblemente niveles inseguros. Presentarán sus resultados en la ACS Fall 2024.

Indagar en la mente de la inteligencia artificial para fabricar mejores antibióticos
American Chemical Society (ACS)

La inteligencia artificial (IA) ha explotado en popularidad, pero al igual que un ser humano, es difícil leer la mente de la IA. La IA explicable (XAI), un subconjunto de la tecnología, podría ayudarnos a hacer justamente eso justificando las decisiones de un modelo.

Powering Enzymes with Light to Make Ammonia
Department of Energy, Office of Science

Converting dinitrogen into ammonia is critical for making fertilizer. Conventional conversion processes use adenosine triphosphate (ATP). Researchers are now working on processes that instead use sunlight, which reduces energy use and greenhouse gas production relative to the ATP process. In this research, scientists created a unique biohybrid that couples nanocrystals to nitrogen-catalyzing enzymes to produce ammonia using sunlight.
