Some Victorian books were dyed with toxic pigments. The latest research on these “poison books” used a technique not previously applied to books to assess a university collection, and the researchers found some volumes had possibly unsafe levels. They will present their results at ACS Fall 2024.
“Golden” turmeric milk has become a staple of any trendy café. Researchers have now developed an efficient method to make a plant-based, instant version that maintains the ingredients’ beneficial properties while also extending its shelf life. They will present their results at ACS Fall 2024.
La leche “dorada” de cúrcuma se ha convertido en un elemento esencial de cualquier cafetería de moda. Ahora, los investigadores han desarrollado un método eficiente para hacer una versión instantánea y vegetal que mantiene las propiedades beneficiosas de los ingredientes al tiempo que prolonga la vida útil. Presentarán sus resultados en la ACS Fall 2024.
Researchers have successfully examined tiny crystallites of noble gas compounds. They report structures of multiple xenon compounds in ACS Central Science.

A study published in ACS’ Environmental Science & Technology estimates that soil stores substantially more mercury than previously thought, and it predicts that increases in plant growth due to climate change may add even more.
The American Chemical Society (ACS) is hosting ACS Fall 2024, its virtual and in-person meeting, with the theme “Elevating Chemistry.” It will take place in Denver on Aug. 18-22.
Un grupo de investigadores que publican en la revista Nano Letters de ACS ha desarrollado un método de creación de imágenes de alta tecnología para detectar la contaminación por pesticidas en niveles inferiores, y su aplicación en la fruta revela que las prácticas actuales de seguridad alimentaria podrían ser insuficientes.
Researchers reporting in ACS’ Nano Letters have developed a high-tech imaging method to detect pesticide contamination at low levels, and its application on fruits reveals that current food safety practices may be insufficient.
Ahora investigadores deACS Central Science demuestran una forma de empaquetar sensores fluorescentes para facilitar su paso a través de la barrera hematoencefálica en ratones, lo que permite mejorar la obtención de imagenología cerebral. Con un mayor desarrollo, la tecnología podría contribuir a avanzar en el diagnóstico y el tratamiento de la enfermedad de Alzheimer.
Now, researchers in ACS Central Science demonstrate a way of packaging fluorescent sensors for easy passage across the blood-brain barrier in mice, allowing for improved brain imaging. With further development, the technology could help advance Alzheimer’s disease diagnosis and treatment.
Los investigadores de ACS Energy Letters informan sobre una batería de iones de litio con componentes totalmente extensibles, incluida una capa de electrolito que puede expandirse un 5000 %, y que conserva su capacidad de almacenamiento de carga después de casi 70 ciclos de carga y descarga.
En un estudio publicado en ACS Central Science, los investigadores han identificado una estrategia para diseñar opioides más seguros. Han demostrado que un opioide experimental, que se une a un sitio no convencional del receptor, suprime el dolor en modelos animales con menos efectos secundarios, especialmente los vinculados a sobredosis fatales.
In a study in ACS Central Science, researchers have identified a strategy to design safer opioids. They showed that an experimental opioid, which binds to an unconventional spot in the receptor, suppresses pain in animal models with fewer side effects — most notably those linked to fatal overdoses.
Researchers in ACS Energy Letters report a lithium-ion battery with entirely stretchable components, including an electrolyte layer that can expand by 5000%, and it retains its charge storage capacity after nearly 70 charge/discharge cycles. Potential applications include flexible electronics.
Many municipal landfills “burp” gas from decomposing organic matter rather than letting it build up. And burps from buried waste containing per- and polyfluoroalkyl substances (PFAS) can release these “forever chemicals” into the air, say researchers in ACS’ Environmental Science & Technology Letters.
To harvest small amounts of humidity, researchers in ACS Energy Letters have developed a compact device with absorbent-coated fins that first trap moisture and then generate potable water when heated.
Journalists who register for the fall meeting of the American Chemical Society (ACS) will have access to about 10,000 presentations on topics including agriculture and food, energy and fuels, health and medicine, sustainability, and more.
The same molecules that create chocolate's aroma might carry some unwanted health effects if there are too many around. According to research published in ACS’ Journal of Agricultural and Food Chemistry, while many of the compounds appeared in chocolate in low enough concentrations to be safe, higher amounts were found in some baked sweet treats.
Advances in electrochromic coatings may bring us closer to environmentally friendly ways to keep inside spaces cool. Researchers in ACS Energy Letters report demonstrating a new electrochromic film design based on metal-organic frameworks (MOFs) that quickly and reliably switch from transparent to glare-diminishing green to thermal-insulating red.
