Headline: Eco-friendly paint most effective against fouling on ships and boats

■ Release Date: 2022.12.12

■ Published by: Chalmers University of Technology

■ Keywords: copper, silicone, paint

■ Abstract:

Emissions from copper-based antifouling paints are a well-known environmental problem. As much as 40 percent of copper inputs to the Baltic Sea come from antifouling paints on ships and leisure boats. According to a new study, this is completely unnecessary. When the researchers compared copper-based antifouling paint with biocide-free silicone-based paint, they found that the environmentally friendly alternative was best at keeping the fouling at bay.

Headline: An integrated, net-negative system captures carbon and produces ethylene

■ Release Date: 2022.12.12

■ Published by: University of Illinois Chicago

■ Keywords: carbon, ethylene, carbon capture

■ Abstract:

Engineers have built a machine that captures carbon from flue gas and converts it to ethylene. The device integrates a carbon capture system with an ethylene conversation system for the first time.

Headline: New life flashed into lithium-ion anodes

■ Published by: Rice University

■ Keywords: graphite, lithium-ion, battery

■ Abstract:

Chemists use flash Joule heating to recover graphite anodes from spent lithium-ion batteries at a cost of about $118 per ton.

Headline: Ingestible biobatteries could allow new view of digestive system

■ Release Date: 2022.12.12

■ Published by: Binghamton University

■ Keywords: biobattery, micro-fuel cell, sensors

■ Abstract:

A new biobattery could power ingestible cameras in the small intestine.

Headline: Nanomaterial influences gut microbiome and immune system interactions

■ Release Date: 2022.12.12

■ Published by: Karolinska Institutet

■ Keywords: nanomaterial, graphene oxide, graphene

■ Abstract:

The nanomaterial graphene oxide -- which is used in everything from electronics to sensors for biomolecules -- can indirectly affect the immune system via the gut microbiome, as shown in a new study on zebrafish.

Headline: Producing 'green' energy -- literally -- from living plant 'bio-solar cells'

■ Release Date: 2022.12.13

■ Published by: American Chemical Society

■ Keywords: solar, cell, bio-solar cell

■ Abstract:

Though plants can serve as a source of food, oxygen and décor, they're not often considered to be a good source of electricity. But by collecting electrons naturally transported within plant cells, scientists can generate electricity as part of a 'green,' biological solar cell. Now, researchers have used a succulent plant to create a living 'bio-solar cell' that runs on photosynthesis.

Headline: A shield for 2D materials that adds vibrations to reduce vibration problems

■ Release Date: 2022.12.15

■ Published by: ARC Centre of Excellence in Future Low-Energy Electronics Technologies

■ Keywords: gallium, graphene, gallium-oxide

■ Abstract:

A new study demonstrates a new, counterintuitive way to protect atomically-thin electronics -- adding vibrations, to reduce vibrations. By squeezing a liquid-metal gallium droplet, graphene devices are painted with a protective coating of gallium-oxide that can cover millimeter-wide scales, making it potentially applicable for industrial large-scale fabrication. The new technique improves device performance as well as protecting 2D materials from thermal vibration in neighboring materials.
