Elena Naumova, professor at the Friedman School of Nutrition Science and Policy at Tufts University, explains wastewater surveillance and testing, the underlying process and the pros and cons of its use.
By trapping light into tiny gaps only a few atoms wide, a team from the NanoPhotonics Centre has magnified optical forces a thousand-fold, strong enough to force atoms into positions that drive chemical reactions more efficiently.
Stacking solar cells increases their efficiency. Working with partners in the EU-funded PERCISTAND project, researchers at the Karlsruhe Institute of Technology (KIT) have produced perovskite/CIS tandem solar cells with an efficiency of nearly 25 percent – the highest value achieved thus far with this technology. Moreover, this combination of materials is light and versatile, making it possible to envision the use of these tandem solar cells in vehicles, portable equipment, and devices that can be folded or rolled up. The researchers present their results in the journal ACS Energy Letters (DOI: 10.1021/acsenergylett.2c00707)

The American Chemical Society's ACS Fall 2022 will be held virtually and in Chicago Aug. 21–25 with the theme “Sustainability in a Changing World.” ACS considers requests for press credentials and complimentary meeting registration from reporters and public information officers at selected institutions.
UC San Diego researchers describe how the microbiomes of people and the homes they live in interact and change each other.
Research work of a biochemistry expert at Chulalongkorn University finds that over 30% of cannabis-flavored drinks randomly tested contain higher THC levels than what is permitted. The public is warned to keep their consumption to moderate levels and that children should refrain from drinking this beverage. The government should control its consumption and warn the people of the benefit and harm of cannabis.
The migration of carbon atoms on the surface of the nanomaterial graphene was recently measured for the first time. Although the atoms move too swiftly to be directly observed with an electron microscope, their effect on the stability of the material can now be determined indirectly while the material is heated on a microscopic hot plate. The study by researchers at the Faculty of Physics of the University of Vienna was published in the journal Carbon.
In ACS’ Journal of Agricultural and Food Chemistry, researchers report that proteins in a model plant-based substitute were not as accessible to cells as those from meat. The team says this knowledge could eventually be used to develop more healthful products.
With the end of the pandemic seemingly nowhere in sight, scientists are still very focused on finding new or alternative drugs to treat and stop the spread of COVID-19. In a first-of-its-kind study, researchers at the University of New Hampshire have found that using an already existing drug compound in a new way, known as drug repurposing, could be successful in blocking the activity of a key enzyme of the coronavirus, or SARS-CoV-2, which causes COVID-19.
Biochemists and molecular biologists will give award lectures at #DiscoverBMB, the society's annual meeting, in March in Seattle.
Today, U.S. Secretary of Energy Jennifer Granholm announced ten U.S. scientists and engineers as recipients of the prestigious Ernest Orlando Lawrence Award for their exceptional contributions in research and development supporting the Energy Department’s missions in science, energy, and national security. Established in 1959, the Lawrence Award recognizes mid-career U.S. scientists and engineers who have advanced new research and scientific discovery in nine categories representing the broad science and engineering missions of DOE and its programs. The awards are among the longest running and most prestigious science and technology awards bestowed by the U.S. Government.
Adding water to the catalytic reaction that converts methane into useful methanol makes the process more effective, but it creates challenges for industry due to steam from the water. Now scientists have identified a common industrial catalyst, copper-zinc oxide, that completes the conversion along different pathways depending on whether water is present or not. This could potentially keep methane, a potent greenhouse gas, out of Earth’s atmosphere and instead turn it into useful products.
A Rutgers scientist is part of an international team that has determined the process for incorporating selenium – an essential trace mineral found in soil, water and some foods that increases antioxidant effects in the body – to 25 specialized proteins, a discovery that could help develop new therapies to treat a multitude of diseases from cancer to diabetes.
Collaborative research from the labs of Daniel Giammar and Jeffrey Catalano finds a lack of available metals may be responsible for more nitrous oxide than previously thought.
The American Cleaning Institute (ACI) previewed the launch of a new ingredient communication tool, ‘What Cleaning Ingredients Do,’ designed to enhance consumer understanding through greater transparency and building trust with consumers.
AACC, a global scientific and medical professional organization dedicated to better health through laboratory medicine, is pleased to announce that Octavia Peck Palmer, PhD, FAACC, has been elected to serve on the AACC board of directors as president-elect starting in August 2022.
URI doctoral student Cali Antolini receives six month fellowship at Argonne National Laboratory in Chicago to research photochemical and photocatalytic reactions and photovoltaic material performance.
The Journal of Chemical Physics, in its commitment to recognizing the excellent work of early-career investigators, is proud to announce the 2021 winners of the JCP Best Paper by an Emerging Investigator Awards. The awardees, Andrew Musser and Yoav Green, were selected for their research on molecular polaritons and electroneutrality breakdown in nanopores, respectively. The award includes a $2,000 honorarium and an invitation to write a perspective article for JCP.
Biomedicines are produced by living cells and are used to treat cancer and autoimmune diseases among other things.
Chemistry is the study of bond formation (or dissociation) between atoms.
