Researchers report quantum-limit-approaching chemical sensing chip

University at Buffalo researchers are reporting an advancement of a chemical sensing chip that could lead to handheld devices that detect trace chemicals—everything from illicit drugs to pollution—as quickly as a breathalyzer ...

Controlling fully integrated nanodiamonds

Using modern nanotechnology, it is possible nowadays to produce structures which have a feature sizes of just a few nanometres. This world of the most minute particles—also known as quantum systems—makes possible a wide ...

When Dirac meets frustrated magnetism

The fields of condensed matter physics and materials science are intimately linked because new physics is often discovered in materials with special arrangements of atoms. Crystals, which have repeating units of atoms in ...

ChipScope – a new approach to optical microscopy

For half a millennium, people have tried to enhance human vision by technical means. While the human eye is capable of recognizing features over a wide range of size, it reaches its limits when peering at objects over giant ...

Ultra-thin camera lenses of the future could see the light of day

In the future, camera lenses could be thousands of times thinner and significantly less resource-intensive to manufacture. Researchers from Chalmers University of Technology, Sweden, now present a new technology for making ...

Light for lithography could pass printed fibers

University of Utah researchers have developed a printed fiber-based light modulating system that combines polymer printing and quantum wave optics, providing a new lithography platform.

Saturable plasmonic metasurfaces for laser mode locking

Plasmonic metasurfaces are artificial 2-D sheets of plasmonic unit cells repeated in a subwavelength array, which give rise to unexpected wave properties that do not exist in nature. In the linear regime, their applications ...

Lithography

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.
