How do organic solar cells work on the inside? The answer lies in structures far too small to see—and difficult to access ...

What happens when a wave passes through some opening? It diffracts - or you like, you could say "bends". If the size of the opening is comparable to the wavelength of the wave, the bending can be ...

In many industries, laser diffraction is used to perform routine particle size analysis. The power of laser diffraction is such that it has started to replace conventional techniques, such as sieving.

A new plasmonic fiber probe uses linearly polarized light and energy recycling for broadband nanofocusing with resolution ...

Today, astronomers seek to observe the faintest and most distant objects possible. Extremely Large Telescopes (ELTs), with apertures in the order of several dozen meters, are the next generation ...

Discover how pairing a 24 keV MetalJet X-ray source with CdTe hybrid photon-counting detectors improves efficiency for ...

Do not exceed 10 mA of current! The electron diffraction tube is fragile. Handle with care. Turn down the high voltage when not in use. It is worthwhile to contrast the diffraction of electrons with ...

The (relatively) ancient art of crystallography has had a huge impact on modern science by showing us the location of atoms within a molecule. The structure of DNA (and how it acts as an information ...

Test for echo: schematic diagram of an object to be imaged (blue blob) and illumination source (concentric circles) inside a randomly shaped cavity. The detector is represented by the two parallel ...

The spectrum of laser technologies available to hackers has gradually widened from basic gas lasers through CO2 tubes, diode lasers, and now fiber lasers. One of the newer entries is the MOPA laser, ...
