The American Chemical Society (ACS) is pleased to announce the appointment of Kimberly Knight as the organization’s next Secretary. As Secretary, Knight will serve as one of the Society’s seven officers.
In a study in ACS Nano, researchers describe swarms of microscale robots (microrobots) that captured bits of plastic and bacteria from water. Afterward, the bots were decontaminated and reused.
Researchers report in ACS Central Science that they have 3D printed a bioink containing plant cells that were then genetically modified, producing programmable materials. Applications could someday include biomanufacturing and sustainable construction.
Estuaries — where freshwater rivers meet the salty sea — are great locations for birdwatching and kayaking. In these areas, waters containing different salt concentrations mix and may be sources of sustainable, “blue” osmotic energy. Researchers in ACS Energy Letters report creating a semipermeable membrane that harvests osmotic energy from salt gradients and converts it to electricity. The new design had an output power density more than two times higher than commercial membranes in lab demonstrations.
Microscopic studies of rodent incisors revealed nano-sized pockets of iron-rich material that form a protective shield, a finding that could improve human dentistry, say researchers in ACS Nano.
Researchers reporting in ACS Nano have constructed a waterproof “e-glove” that wirelessly transmits hand gestures made underwater to a computer that translates them into messages. The new technology could someday help divers communicate better with each other and with boat crews on the surface.
To better understand COVID-19’s spread during the pandemic, public health officials expanded wastewater surveillance. These efforts track SARS-CoV-2 levels and health risks among most people, but they miss people who live without shelter, a population particularly vulnerable to severe infection.
Researchers report in ACS Energy Letters that repositioning the electrode in a “blue energy” harvesting device — from the center of a see-sawing liquid-filled tube to the end where the water crashes with the most force — dramatically increased the amount of wave energy that could be harvested.
Choosing paint for your home brings a lot of options: What kind of paint, what type of finish and what color? Water-based paints have emerged as “greener” and less smelly than solvent-based options. And they are often advertised as containing little-to-no volatile organic compounds (VOCs).
Though it’s known that tiny sites like soot and bacteria help water freeze, the fundamentals of how ice forms are vague. Scientists have now developed a theoretical model showing how structural details on surfaces influence water’s freezing point. They will present their results at ACS Spring 2024.
The increasing use of lithium-ion rechargeable batteries likely means more environmental contamination. Researchers have explored how lithium accumulates in crawfish, with implications for the environment and public health. They will present their results at ACS Spring 2024.
Dropping wearable electronics, or hitting them really hard, usually breaks the devices. Now, researchers report on a flexible and electrically conductive material with “adaptive durability,” getting stronger when it is hit. They will present their results at ACS Spring 2024.
Quantum dot research just won a Nobel Prize, and now, the applications for nontoxic quantum dots are being expanded. One team of researchers has designed carbon- and sulfur-based dots to help clean up the environment. They will present their results at ACS Spring 2024.
Many disposable diapers and sanitary pads contain plastic and need centuries to decompose. Now, researchers are replacing the plastic with parts made from food waste. That could lead to biodegradable diapers and pads that could be used as fertilizer. They’ll present their results at ACS Spring 2024.
Rabih Al-Kaysi’s molecular motors look like tiny worms, but they’re actually crystallized molecules that move in response to light. These machines could someday solve real-world problems, like being used as drug-delivery robots. The researchers will present their results at ACS Spring 2024.
Vapes are thought to be a “safer” way to consume cannabis, but they present their own risks. Researchers have discovered toxic metal particles in vaping liquids even before first use of the device, and this toxicity was worse in illicit products. They will present their results at ACS Spring 2024.
Mucus is critical to human health. To explore how, researchers synthesized its major component, sugar-coated proteins called mucins, and discovered that changing the mucins of healthy cells to be more cancer-like made cells act more cancer-like. They will present their results at ACS Spring 2024.
Could a pill replicate the benefits of exercise? Researchers have identified new compounds that seem to mimic some benefits of exercise in rodent cells. This discovery could help treat those with muscle wasting and other conditions. The scientists will present their results at ACS Spring 2024.
Building materials are major contributors to global carbon dioxide emissions. So scientists have designed a composite decking material that stores more carbon dioxide than is required to manufacture it, providing the first “carbon-negative” option. They will present their results at ACS Spring 2024.
Ants are commonly eaten in some parts of the world, roasted and eaten whole or ground and used to add flavor and texture to dishes. Each species has its own unique flavor, and researchers now report the aroma profiles of four species of edible ants. They will present their results at ACS Spring 2024.
