Researchers developed a one-pot process to transform aromatic ketones into esters, simplifying the reaction process, reducing reaction times, and minimizing purification steps. The method enables seven different chemical transformations and has shown notable stability and reusability, making it scalable for industrial applications.
Research reveals Kama'ehu volcano in Hawaii has erupted five times in the past 150 years. The new study uses mass spectrometry to measure radium-226 in lava samples, revealing a frequency of eruptions around 30 years. This slower rate is linked to sluggish mantle upwelling on the margin of the Hawaiian plume.
Researchers have identified the genetic secrets behind skullcap's anti-cancer activity, enabling the production of synthetic compounds. The discovery is expected to lead to more sustainable and rapid synthesis of cancer-fighting molecules.
A team of scholars at the University of Bologna revived and studied ancient alchemical texts, then put procedures into practice in the laboratory. The results revealed unexpected methods for mercury extraction and the use of substances like natron and iron in sublimation processes.
A new study reveals that DFDT, a faster and less toxic insecticide than DDT, was created by German scientists during WWII. The compound kills insects more quickly and in smaller amounts, potentially minimizing its environmental impact.
OpenStax College plans to add six more titles by 2015, bringing the total to 25 books, with estimated savings of $750 million for college students. The nonprofit publisher's textbooks are peer-reviewed and equal in quality to costly alternatives.
Researchers found that pre-eruptive mixing within magma chambers, triggered by older cooler magma mixing with younger hotter magma, is the common event before catastrophic eruptions. This discovery could prove invaluable in future hazard and risk assessment on islands prone to volcanic activity.
A study by Michigan State University scholar Roger Baldwin finds that only 130 of the original 212 liberal arts colleges remain, with many evolving into career-oriented institutions. The trend threatens to diminish America's renowned higher education system.
A recent article in Nature Chemistry outlines why chemistry has a tarnished public image, citing 'chemophobia' as the reason. The authors propose five communication strategies to improve public engagement with chemistry, including practice research-driven communication and framing key messages to prompt engagement.
After years of effort, a team from The Scripps Research Institute has finally achieved the synthesis of Palau'amine, a naturally occurring compound with pharmaceutical promise. The breakthrough involves 25 steps and utilizes an oxidation reaction that simplifies the process, paving the way for further research and potential commercial ...
Scientists developed a nondestructive 'sniff' test that analyzes gases emitted from old books and documents, identifying 15 VOCs as markers for paper degradation. This method preserves prized paper-based objects without destroying them.
Michigan State University researchers Kristie Macrakis and Ryan Sweeder have successfully recreated the chemical formula for invisible ink used by East Germany's Stasi. The team, which includes undergraduate students, developed a chemistry lab dubbed the 'Spy Lab' to teach students about catalysis and other scientific concepts.
Researchers are analyzing Stardust samples to study the structure and chemistry of cometary material, providing clues about the solar system's history. The team is using advanced spectroscopic techniques to identify organic compounds and isotopic signatures in the ancient grains.
A Scripps Institution of Oceanography professor and his colleague revisit the famous Miller experiment to recreate a prebiotic soup that may have been present on early Earth. The report traces the history of the experiment and highlights its significance in transforming the study of life's origin into a respectable field of inquiry.
George Kauffman, a renowned Fresno chemist, has won the ACS Helen M. Free Award for his outstanding contributions to public outreach in chemistry. With over 1750 scientific papers and 16 books on science for general readers, Kauffman is celebrated for his work in making chemistry accessible to the public.
The American Chemical Society recognizes Charles Martin Hall's groundbreaking work on producing aluminum metal from ore, revolutionizing modern life. The ceremony commemorates the commercialization of aluminum in North America, marking a significant milestone in the history of chemistry.
Historian Alan J. Rocke presents a symposium on the history of futurism in chemistry, exploring divergent visions of science in the year 2000. The event highlights the accuracy of 19th-century predictions about the 20th century and showcases the evolution of chemistry.
Dr. Jeremy Knowles, Harvard University Dean, to discuss two millennia of lead toxicity at the American Chemical Society meeting in New Orleans. The speech highlights progress made on remedial action taken in recent decades.
Researchers developed a new technique using combinatorial chemistry to screen thousands of catalysts simultaneously, reducing time by fractions. The method enables potential improvements in fuel emission controls, solar energy harvesting, drug preparation, and converting natural resources into useful products.
