Advancing metasurface manufacturing with water-soluble mold

When will the protruding rear camera on smartphones become obsolete? The implementation of a metasurface, which completely disregards the properties of light, promises to reduce the thickness of a camera lens to 1/10,000 ...

Apochromatic X-ray focusing

A team of scientists from the Paul Scherrer Institut, the University of Basel and DESY have demonstrated the first-ever realization of apochromatic X-ray focusing using a tailored combination of a refractive lens and a Fresnel ...

Shrinking hydrogels enlarge nanofabrication options

Researchers from Carnegie Mellon University and the Chinese University of Hong Kong have developed a strategy for creating ultrahigh-resolution, complex 3D nanostructures out of various materials.

Team develops graphene-based nanoelectronics platform

A pressing quest in the field of nanoelectronics is the search for a material that could replace silicon. Graphene has seemed promising for decades. But its potential has faltered along the way, due to damaging processing ...

Lithography (from Greek λίθος - lithos, 'stone' + γράφειν - graphein, 'to write') is a method for printing using a stone (lithographic limestone) or a metal plate with a completely smooth surface. Invented in 1796 by Bavarian author Alois Senefelder as a cheap method of publishing theatrical works, lithography can be used to print text or artwork onto paper or other suitable material.
