The spectrum of laser technologies available to hackers has gradually widened from basic gas lasers through CO2 tubes, diode ...

The reproducibility of published experimental results has recently attracted attention in many different scientific fields. The lack of availability of original primary scientific data represents a ...

The diffraction spikes so familiar to us in space images are an intrinsic property of the telescope. Reflecting telescopes have two mirrors: a large primary and a smaller secondary. Light hits the ...

Researchers have succeeded in simultaneously observing the reorganizations of atomic positions and electron distribution during the transformation of the “smart material” vanadium dioxide from a ...

Single-crystal X-ray diffraction (SC-XRD) is often referred to as the gold standard of sample characterisation, offering three-dimensional structure of both molecules and their crystalline packing, ...

Using high-powered laser beams, researchers have simulated conditions inside a planet three times as large as Earth. Scientists have identified more than 2,000 of these “super-Earths,” exoplanets that ...

Non-ambient diffraction is a powerful tool for identifying the effects of temperature, humidity, pressure, or atmosphere on a sample. Materials exposed to non-ambient environments tend to have ...

This is a preview. Log in through your library . Abstract Recent resolving power measurements by Burtt & Catton give high values and demand the re-examination of insect vision theories. Their results ...
