“Pantry” science: MIT researchers grow carbon nanotubes using common kitchen ingredients

When the subject of carbon nanotubes is brought up, most people probably won’t think of something that can be cooked up in a kitchen. However, a team of researchers at the Massachusetts Institute of Technology have done just that – creating carbon nanotubes with the help of common household materials. Led by Richard Li, a graduate student in […]

Seashell-inspired shatterproof glass: Researchers engineer strong composite glass based on mother of pearl that can resist impact

Despite their delicate appearance, seashells are surprisingly durable. This unexpected durability comes from the tough, impact-resistant substance known as nacre, also known as mother of pearl. Nacre is an organic-inorganic composite material that also gives seashells their signature iridescence. It is made up of microscopic calcium carbonate tablets mortared together by proteins. Arranged like bricks, […]

Scientists develop new insulation material inspired by polar bears

It’s a well-known fact that living organisms have evolved well-adapted structures and materials over geological time through a process called natural selection. These include unique properties such as hydrophobicity or natural waterproofing, heat retention, bioluminescence and coloration as well as unique methods of flight and locomotion. Throughout history, scientists and engineers have made it a […]

The quest to cool your electronics continues: New polymer can disperse heat

Overheating gadgets and devices may soon become a thing of the past, thanks to a new material developed by scientists at Rice University. Researchers from Rice University’s Brown School of Engineering recently unveiled a nanocomposite material that shows great promise as a superior dielectric or insulating material, which can then be used for flexible electronics, energy storage and electronic devices. Created […]

Advancing detection and diagnosis: Scientists enable 3D printers to print glass using material called chalcogenide glass

Additive manufacturing systems have added another challenging material to the list of things they may print on the fly. Canadian researchers demonstrated the capability to print out chalcogenide glass with a modified 3D printer. Chalcogenide glass is a type of covalently bonded glass that contains certain chemicals called “chalcogens.” It sees extensive use in optical […]

Understanding metallic glass: Scientists discover liquid metals form structures that help solidify metallic glasses

When you think of liquids, they usually don’t form structures that stop their atoms and molecules from flowing freely. But Yale researchers demonstrated that the right circumstances allow liquid metals to create the rigid shapes required by metallic glasses. Furthermore, they proposed that the structures formed by liquid metals might play a significant role in […]

Bioengineers discover “breakthrough” technique: 3D-printed organs to be available in the next two decades

Additive manufacturing systems have come one step closer to printing out whole, working organs for emergency medical transplants. Researchers reported 3D printing a complete system of blood vessels found on a major organ. Every day, around 20 patients who desperately need an organ transplant die before ever getting one. There are not enough donors – […]

Manufacturing breakthrough: Scientists can now weld glass and metal together

The manufacturing industry has recently welcomed what might prove a breakthrough technology. Scottish researchers showed off a new welding method that uses an incredibly fast laser to fuse together glass and metal. Glass and metal are two of the most common classes of materials used for various purposes. Due to their very different thermal properties, […]

Healing with hair: Can nanostructures from human hair be used to design smart biomedical materials?

In the future, your hair may provide the natural ingredients for making biomedicine that treats illness. A recent Chinese study has shown that the tiny structures in human hair might be turned into useful biomaterials. Wuhan University (WHU) researchers examined the melanin and keratin polymers in hair. They isolated the micro- and nanostructures found on these substances. […]

Researchers are developing an energy-efficient method of converting methane into carbon nanotubes

The U.S. Department of Energy (DOE) is looking to get the most value out of the vast natural gas deposits in North America. It recently provided a big federal grant to Rice researchers, who would come up with an efficient yet inexpensive way to turn methane gas into carbon nanotubes. Being an allotrope, or alternative form of […]
