    en.wikipedia.org/wiki/X-ray_lithography

    X-ray lithography is a process used in semiconductor device fabrication industry to selectively remove parts of a thin film of photoresist. It uses X-rays to transfer a geometric pattern from a mask to a light-sensitive chemical photoresist , or simply "resist," on the substrate to reach extremely small topological size of a feature.

    HRTF filtering effect. A head-related transfer function (HRTF) is a response that characterizes how an ear receives a sound from a point in space. As sound strikes the listener, the size and shape of the head, ears, ear canal, density of the head, size and shape of nasal and oral cavities, all transform the sound and affect how it is perceived, boosting some frequencies and attenuating others.

  7. X-ray tube - Wikipedia

    en.wikipedia.org/wiki/X-ray_tube

    An X-ray tube is a vacuum tube that converts electrical input power into X-rays. [ 1] The availability of this controllable source of X-rays created the field of radiography, the imaging of partly opaque objects with penetrating radiation. In contrast to other sources of ionizing radiation, X-rays are only produced as long as the X-ray tube is ...

  8. X-ray notation - Wikipedia

    en.wikipedia.org/wiki/X-ray_notation

    X-ray notation is a method of labeling atomic orbitals that grew out of X-ray science. Also known as IUPAC notation, it was adopted by the International Union of Pure and Applied Chemistry in 1991 as a simplification of the older Siegbahn notation. [1] In X-ray notation, every principal quantum number is given a letter associated with it.

  9. X-ray absorption spectroscopy - Wikipedia

    en.wikipedia.org/wiki/X-ray_absorption_spectroscopy

    X-ray absorption spectroscopy. X-ray absorption spectroscopy (XAS) is a widely used technique for determining the local geometric and/or electronic structure of matter. [ 1] The experiment is usually performed at synchrotron radiation facilities, which provide intense and tunable X-ray beams. Samples can be in the gas phase, solutions, or solids.
