You can now 3D print the world’s lightest material – graphene aerogel

YES PLEASE. It’s 7.5 times lighter than air, and a cubic metre of the stuff weighs just 160 grams. It’s 12 percent lighter than the second lightest material in the world – aerographite – and you can balance a few cubic centimetres of the stuff on a dandelion head. Water is about 1,000 times as […]

A new symmetry underlies the search for new materials

A new type of symmetry operation developed by Penn State researchers has the potential to quicken the search for new advanced materials that range from tougher steels to new types of electronic, magnetic, and thermal materials. With further developments, this technique could also impact the fields of computational materials design. “In the physical sciences, making […]

Black Phosphorous Might Beat Graphene

Can a material be too good at conducting electricity? Scientists developing a new one-atom-thick material to rival graphene, the carbon-based darling of the 2D world, think so. This new 2D material is known as black phosphorous, and a new report in the journal Science shows that it can solve a problem that has plagued graphene: […]

Spiders Ingest Nanotubes, Then Weave Silk Reinforced with Carbon

Spiders sprayed with water containing carbon nanotubes and graphene flakes have produced the toughest fibers ever measured, say materials scientists. Spider silk is one of the most extraordinary materials known to science. The protein fiber, spun by spiders to make webs, is stronger than almost anything that humans can make. The dragline silk spiders use […]

Graphene multiplies the power of light

Could graphene turn light to electricity? Scientists have shown that graphene can convert a single photon into multiple electrons, showing much promise for future photovoltaic devices.
Graphene is a material that has gathered tremendous popularity in recent years, due to its extraordinary strength and light weight. It can be generated by literally peeling it off from graphite, or by growing it on top of various materials, which makes its production cost-effective.

Oxygen extends graphene’s reach

Carbon in the form of graphene—a two-dimensional sheet of carbon atoms in a hexagonal network—is strong, flexible and an excellent electrical conductor. These characteristics make the material very attractive for applications as diverse as electronics, desalination and energy storage. The addition of other elements to the surface of graphene can modify the material’s physical and […]

Graphene Made in Kitchen Blender–but Don’t Try This at Home

Graphene is some amazing stuff, with amazing properties that researchers are continually finding new ways to employ. It is basically a lattice of carbon atoms one atom thick. Called a “wonder material” by the American Physical Society, graphene is “a million times thinner than paper, stronger than diamond, more conductive than copper.” And since it […]
