The electronic and optical devices that we use on a daily basis, such as mobile phones, LEDs and solar cells use transistors and other constituents that are consistently getting smaller and more ...

Electron diffraction is a powerful analytical technique used to study the atomic structure of materials. It involves the interaction of a beam of electrons with a crystalline sample, resulting in a ...

This work, part II in a series, presents an efficient method for evaluation of wave scattering by doubly periodic diffraction gratings at or near what are commonly called 'Wood anomaly frequencies'.

For pharmaceuticals, knowing the chemical composition is not enough - molecular geometry and crystal structure also play an important role in a drug's activity. By using a method based on electron ...

The technique is typically carried out on a single crystal, but because not all substances easily form good quality crystals, powder X-ray diffraction (PXD) is sometimes used instead. Powder X-ray ...

Phononic crystals are artificially engineered materials that consist of periodic structures designed to control and manipulate the propagation of phonons, which are quasiparticles representing the ...

Particle size analysis is crucial to quality control and product development in a number of key industries including aerosols, construction, food and beverage, paint and coatings, and pharmaceuticals.
