Newswise — A solution to injuries from slips and falls may be found underfoot — literally. The footpads of geckos have hydrophilic (water-loving) mechanisms that allow the little animals to easily move over moist, slick surfaces. Researchers in ACS Applied Materials & Interfaces report using silicone rubber enhanced with zirconia nanoparticles to create a gecko-inspired slip-resistant polymer. They…
Zaps of static electricity might be a wintertime annoyance, but to certain scientists, they represent an untapped source of energy. Using a device called a triboelectric nanogenerator (TENG), mechanical energy can be converted into electrical energy using triboelectric effect static. Many TENGs contain expensive, specially fabricated materials, but one team has instead used inexpensive store-bought…
A carnation-like nanostructure could someday be used in bandages to promote wound healing. Researchers report in ACS Applied Bio Materials that laboratory tests of their nanoflower-coated dressings demonstrate antibiotic, anti-inflammatory and biocompatible properties. They say these results show these tannic acid and copper(II) phosphate sprouted nanoflower bandages are promising candidates for treating infections and inflammatory conditions. Nanoflowers are tiny,…
Rising carbon dioxide levels affect more than just the climate; they also affect the chemistry of the oceans. When saltwater absorbs carbon dioxide, it becomes acidic, which alters the aquatic animal ecosystem. But how exactly does ocean acidification impact animals whose genetic makeup can shift depending on environmental cues? A study published in ACS’ Environmental Science…
WASHINGTON, Jan. 23, 2025 — Press registration is now open for the spring meeting of the American Chemical Society (ACS). ACS Spring 2025 will be held in San Diego, in addition to the ACS Spring 2025 Digital Meeting, on March 23-27. Cutting-edge developments on a range of scientific topics will be featured, and embargoed press…
Large batteries for long-term storage of solar and wind power are key to integrating abundant and renewable energy sources into the U.S. power grid. However, there is a lack of safe and reliable battery technologies to support the push toward sustainable, clean energy. Now, researchers reporting in ACS Central Science have designed a cost-effective and environment-friendly aluminum-ion…
Most batteries are rigid and incompatible with water. But people work and play in oceans and estuaries, and they could benefit from flexible and saltwater-safe power sources. Now, researchers report in ACS Applied Materials and Interfaces a yarn-like battery prototype that works when immersed in seawater. They knotted the rechargeable strands into a fishing net that lit…
Wildfires that burn homes and vehicles could expose people to dangerous airborne compounds through ash and smoke. Research published in ACS ES&T Air has shown that people returning to their unburned homes may also experience health symptoms months after a nearby fire is extinguished. Through a survey of people affected by the 2021 Marshall Fire in Boulder,…
DNA stores the instructions for life and, along with enzymes and other molecules, computes everything from hair color to risk of developing diseases. Harnessing that prowess and immense storage capacity could lead to DNA-based computers that are faster and smaller than today’s silicon-based versions. As a step toward that goal, researchers report in ACS Central…
Newswise — Wearing sunscreen is important to protect your skin from the harmful effects of UV radiation but doesn’t cool people off. However, a new formula, described in ACS’ Nano Letters, protects against both UV light and heat from the sun using radiative cooling. The prototype sunblock kept human skin up to 11 degrees Fahrenheit (6 degrees…
