(Nanowerk Spotlight) X-rays are at the short wavelength, high energy end of the electromagnetic spectrum (only gamma rays have shorter wavelength and carry more energy) and this form of radiation is primarily used for crystallography and diagnostic radiography. Due to the high energy they carry, and because their wavelengths are on the order of the size of atoms, X-rays can penetrate deeply into a material. Chances are you've had an 'X-ray' taken at least once in your life by your doctor or dentist but you will have also encountered X-ray machines at airport security (the machines your carry-on luggage is going through). X-rays play an important role in microscopy and X-ray microscopes have become very powerful scientific instruments for domains such as nanotechnology, materials and life sciences, microelectronics, and chemistry.
