Electron excitation. Electron excitation is the transfer of a bound electron to a more energetic, but still bound state. This can be done by photoexcitation (PE), where the electron absorbs a photon and gains all its energy [ 1] or by collisional excitation (CE), where the electron receives energy from a collision with another, energetic ...
Chyme or chymus ( / kaɪm /; from Greek χυμός khymos, "juice" [ 1][ 2]) is the semi-fluid mass of partly digested food that is expelled by the stomach, through the pyloric valve, into the duodenum [ 3] (the beginning of the small intestine ). Chyme results from the mechanical and chemical breakdown of a bolus and consists of partially ...

Mucus is able to absorb water or dehydrate through pH variations. The swelling capacity of mucus stems from the bottlebrush structure [32] of mucin within which hydrophilic segments provide a large surface area for water absorption. Moreover, the tunability of swelling effect is controlled by polyelectrolyte effect.
By recording the attenuation of light for various wavelengths, an absorption spectrum can be obtained. In physics, absorption of electromagnetic radiation is how matter (typically electrons bound in atoms) takes up a photon 's energy — and so transforms electromagnetic energy into internal energy of the absorber (for example, thermal energy ).
A crossword (or crossword puzzle) is a word game consisting of a grid of black and white squares, into which solvers enter words or phrases ("entries") crossing each other horizontally ("across") and vertically ("down") according to a set of clues. Each white square is typically filled with one letter, while the black squares are used to ...
