Due to their high porosity, metal-organic frameworks (MOFs) are regarded as promising materials for innovative applications, ...

A laser pointer shining on a diffraction grating or CD creates a series of diffraction spots depending on the spacing of the lines or pits in the grating or CD and the wavelength emitted by the laser.

X-ray diffraction methods lie at the foundation of materials science. Determination of the crystal structures of natural minerals and, later, of crystals grown in the laboratory led to our ...

IF a fine beam of homogeneous cathode rays is sent nearly normally through a thin celluloid film (of the order 3 × 10 6 cm. thick) and then received on a photographic plate 10 cm. away and parallel to ...

Have you ever visited somewhere new and then suddenly you’re overcome with a peculiar feeling of familiarity - as though you’d been there before. Weird, huh? Well, this isn’t the plot of a sci-fi ...

As children’s emotions develop, there are bound to be ups and downs for both them and you as a parent. What makes it difficult is that they take time to be able to both understand and express clearly ...
