“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 […]

Physicists develop new material that could be used for “high-efficiency, lower-cost solar cells”
Researchers have not yet solved the biggest weakness of solar panels – their inability to produce power when there is no steady source of bright light. However, they were happy to announce that they have increased the efficiency of perovskite solar cells to take advantage of the limited daylight hours. University of Toledo (UT) researcher Dr. […]

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 […]

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, […]

Sustainable sports equipment? It’s now possible with the Gigabot X, an open-source industrial 3D printer
An innovative approach to 3D printing may open the door to sustainable outdoor sporting goods. Fused particle fabrication (FPF) allows an additive manufacturing system to create skateboards and snowshoes from recycled plastic. The FPF method makes it possible to use waste plastic as feed material for a 3D printer. The resulting end products meet the special requirements of […]

Single-use no more: Plastic bottles can be upcycled to more durable materials
Single-use plastics cause plastic pollution, a problem that affects rivers, lakes, and oceans. To address this concern, researchers from the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) developed a recycling process that turns various materials made of polyethylene terephthalate (PET) into other useful products that will last longer. NREL’s research was published in the journal Joule. What is […]

Biodegradable “transparent” timber works just as well as glass in windows
Swedish researchers fiddled with wood until they managed to turn it technically transparent. They also made the biodegradable material capable of absorbing heat from sunlight and releasing it during colder periods. If used in the windows of buildings, the revolutionary material might help save energy by reducing the need for artificial heating and cooling. It […]
