X-ray photoelectron spectroscopy of hydrogen and helium

For the first time scientists measured the vibrational structure of hydrogen and helium atoms by X-rays. The results disprove the misconception that it's impossible to obtain X-ray photoelectron spectroscopy (XPS) spectra ...

Covalently modified two-dimensional arsenic

The discovery of graphene, a material made of one or very few atomic layers of carbon, started a boom. Today, such two-dimensional materials are no longer limited to carbon and are hot prospects for many applications, especially ...

Life's building blocks observed in spacelike environment

Where do the molecules required for life originate? It may be that small organic molecules first appeared on earth and were later combined into larger molecules, such as proteins and carbohydrates. But a second possibility ...

Graphene forged into three-dimensional shapes

Researchers from Finland and Taiwan have discovered how graphene, a single-atom-thin layer of carbon, can be forged into three-dimensional objects by using laser light. A striking illustration was provided when the researchers ...
