Its Bragg diffraction will resemble that of a powder but, with a small enough beam and a typical grain size of around a micrometre, the individual grains can still be separated. Even highly ...

The individual silica nanoparticles (glass beads, basically) are clear, but when packed together in certain configurations ...

Laser diodes are semiconductors that generate light and amplify it using repeated reflection or "optical feedback." Once the ...

Researchers in Germany have developed a special technique that will allow better control over atomic reflections in quantum ...

What is Bragg Coherent Diffraction Imaging? Bragg coherent diffraction imaging (BCDI) is a powerful X-ray imaging technique that allows researchers to visualize the internal structure and strain ...

Dichroic mirror pulses act like velocity-selective traffic controllers for atoms by directing the particles with correct ...

Photonic crystal surface-emitting lasers or PCSELs are laser diodes that generate laser beams through controlled light wave interaction within a photonic crystal structure. In a recent study, ...
