Thermoset polymers, found in car parts and electrical appliances, have to be durable and heat-resistant, but typically cannot be easily recycled or broken down after use. MIT chemists have now developed a way to modify thermoset plastics that allows them to be more easily broken down without compromising their mechanical strength. Image: stock image
Chemists have developed a way to modify thermoset plastics with a chemical linker that makes it much easier to recycle them, but still allows them to retain their mechanical strength.
Thermosets, which include epoxies, polyurethanes, and rubber used for tires, are found in many products that have to be durable and heat-resistant, such as cars or electrical appliances...

A recently published study led by Virginia Commonwealth University researchers sheds new light on how water interacts with the nanomaterial graphene, a single, thin layer of carbon atoms arranged in a hexagonal honeycomb lattice.
The researchers’ findings could hold implications for a variety of applications, including sensors, fuel cell membranes, water filtration, and graphene-based electrode materials in high-performance supercapacitors.
The study, “Solvent–Solvent Correlations across Graphene: The Effect of Image Charges,” was published in the American Chemica...

Scientists have found the interstellar organic matter could produce an abundant supply of water by heating, suggesting that organic matter could be the source of terrestrial water.
There remains a number of mysteries on our planet including the elusive origin of water on the earth. Active studies suggested that terrestrial water had been delivered by icy comets or meteorites containing hydrous silicates that came from outside the “snow line” – the boundary beyond which ice can condense due the low temperatures...
These powder samples will be fabricated to become the cobalt-free cathode.
Researchers say they’ve cracked the code to a cobalt-free high-energy lithium-ion battery, eliminating the cobalt and opening the door to reducing the costs of producing batteries while boosting performance in some ways.
For decades, researchers have looked for ways to eliminate cobalt from the high-energy batteries that power electronic devices, due to its high cost and the human rights ramifications of its mining. But past attempts haven’t lived up to the performance standards of batteries with cobalt.
Researchers from the Cockrell School of Engineering at The University of Texas at Austin say they’ve cracked the code to a cobalt-free high-energy lithium-ion battery, eliminating the cobalt and opening th...
