The US Environmental Protection Agency is reexamining the health effects of bisphenol A. A chemist explains why BPA is in plastics and why it’s hard to find a safe replacement.
The ability to store information is central to learning and the field of artificial intelligence. Researchers have shown how a unique material shows basic learning properties similar to that of slugs.
More than two-thirds of the world’s energy is wasted as heat. Thermoelectric materials can convert unwanted heat into electricity, but finding the best ones has been slow.
Throughout human history, clay has played a role in many different industries. Its unique properties make it suited for a wide applications in widely ranging industries.
Chemicals found in food and solar cell technology have an interesting history – as my own research shows.
Batteries power much of modern life, from electric and hybrid cars to computers, medical devices and cellphones. But unless they’re made easier and cheaper to recycle, a battery waste crisis looms.
More companies are selling products that claim to keep you cool on hot days. But it turns out that common materials used in sports clothing may not always be the best.
Making technology such as a new smartphone that can you can roll, fold and bend requires new ways to manufacture.
Is it too much to dream of batteries that are part of the structure of an item, helping to shape the form of a smartphone, car or building while also powering its functions?
We know how to stop solid minerals converting to a liquid state mid voyage – so why does it still happen?
A geologist explains the basics about these elements, which are crucial for modern electronics.
World Cup jerseys have to please players, national officials, FIFA rulemakers and – perhaps most importantly – fans who buy them to show support for their teams.
‘Bendable concrete’ is not an oxymoron. Mimicking designs found in nature, engineers are making concrete that gives under stress without shattering – an advance that could improve US infrastructure.
Less-toxic hair dye would be a great invention. But discounting the risks that come with nanoparticles could undermine other efforts to protect human health and environmental from their effects.
No longer in fanciful coats or button-down shirts with neckties, Olympians compete in uniforms specially designed and engineered for maximum performance.
Highly engineered composite materials let skis ride smoothly, carve neatly and turn quickly – for top athletes and regular consumers alike.
Advanced materials that seem like they come from Star Trek are becoming reality today.
Bio-inspiration takes cues from natural structures that do certain things very effectively. One example: the strong but flexible fibers that sea sponges use to anchor themselves to the ocean floor.
Research on molecular machines won last year’s Nobel Prize in chemistry. Now scientists have figured out a way to get these tiny molecules to join forces and collaborate on real work on a macro scale.
Coating paper with an inexpensive thin film can allow users to print and erase a physical page as many as 80 times. That reduces both the cost and the environmental effects of paper use.
