An atomic look at lithium-rich batteries


Credit: Carnegie Mellon University and Northeastern University
Batteries have come a long way since Volta first stacked copper and zinc discs together 200 years ago. While the technology has continued to evolve from lead-acid to lithium-ion, many challenges still exist like achieving higher density and suppressing dendrite growth. Experts are racing to address the growing, global need for energy-efficient and safe batteries.
The electrification of heavy-duty vehicles and aircraft requires batteries with more energy density. A team of researchers believes a paradigm shift is necessary to make a significant impact in battery technology for these industries. This shift would take advantage of the anionic reduction-oxidation mechanism in lithium-rich cathodes. Findings published in ....

Civil engineering doctoral student earns National Science Foundation fellowship


Credit: UT Arlington
Kelly Patterson, a doctoral student in the Civil Engineering Department at The University of Texas at Arlington, has earned a National Science Foundation (NSF) Graduate Research Fellowship.
The Graduate Research Fellowship Program recognizes and supports outstanding graduate students in NSF-supported science, technology, engineering and mathematics disciplines and provides recipients with a three-year stipend of $34,000 annually along with a $12,000 cost-of-education allowance for tuition and fees. Participants are also provided opportunities for research and professional development at institutions and laboratories worldwide.
I m grateful to have received this fellowship because it ll allow me to move to campus full-time, Patterson said. But the real value is in the network it provides, with access to NSF supercomputers, conferences and fellow graduate students. The support and resources I ll have at my disposal are not as accessible in a tra ....

A research group at KAIST has engineered bacterial strains capable of producing three carotenoids and four violacein derivatives, completing the seven colors in the rainbow spectrum. The research team integrated systems metabolic engineering and membrane engineering strategies for the production of seven natural rainbow colorants in engineered
Escherichia coli strains. The strategies will be also useful for the efficient production of other industrially important natural products used in the food, pharmaceutical, and cosmetic industries. ....

Study shows new links between high fat diets and colon cancer


 E-Mail
For decades, physicians and dieticians have urged people to limit their intake of high fat foods, citing links to poor health outcomes and some of the leading causes of death in the U.S., such as diabetes, heart disease and cancer.
According to the Centers for Disease Control and Prevention, dietary components high in saturated fats such as red meat are thought to be risk factors for colon cancer. Diet is thought to strongly influence the risk of colorectal cancer, and changes in food habits might reduce up to 70% of this cancer burden.
Other known epidemiological risk factors are family history, inflammatory bowel disease, smoking and type-2 diabetes. ....
