Scientists Unravel New Type of Atomically Thin Carbon Material
Written by AZoNanoMay 21 2021
Carbon occurs in different forms in nature. Apart from graphite and diamond, there are some recently discovered forms with surprising properties.

For instance, graphene, having a thickness of only one atomic layer, is the thinnest known material and its exceptional properties make it a highly exciting candidate for applications such as high-tech engineering and future electronics.

Our world would be lost without light. The human eye detects visible light which allows us to see the color and size of objects. But invisible light, like infrared radiation, that our eyes can’t see and is emitted by food, drugs, and other materials, can be filled with hidden information on chemical composition. Possessing the super-vision to detect this light would therefore prove invaluable in many industries such as the agri-food sector. MantiSpectra – a TU/e spin-off company – is developing innovative spectral sensing devices to measure and decode these invisible light signals.
Spectrometers collect light, break it apart, and tease valuable information from it. Here, “light” could be the visible light our eyes detect or invisible electromagnetic waves like infrared radiation, which is used in optical communications and also produced by chemical reactions in crops and in stars like our Sun.

It’s tornado season, as this week’s hail and severe storm warnings around New York and New Jersey can attest. The Northeast isn’t known for these violent windstorms, a reputation typically reserved for the Midwest and the South. Six died during a tornado in Alabama last month.
But the tri-state area is expected to face more severe thunderstorms and tornadoes as the climate warms. These unfamiliar weather events will put these communities at higher risk because they’re not used to preparing for them. Two counties in New York and one in New Jersey already fall into the top five riskiest counties in the country for tornado weather, according to the National Risk Assessment by the Federal Emergency Management Agency (FEMA).
