Yield
The amount of product obtained in a chemical reaction. Theoretical yield is the maximum possible amount calculated from stoichiometry; actual yield is what is actually obtained. Pe…
Yield Strength
Yield strength is the stress at which a material begins to deform plastically (permanently) — below this stress, deformation is elastic (recoverable). It is a critical material pro…
Ylide
A neutral dipolar molecule containing formal positive and negative charges on adjacent atoms, neither of which carries a hydrogen atom. Phosphorus ylides (used in Wittig reactions)…
Young's Modulus
A measure of the stiffness of an elastic material (tensile elasticity), defined as the ratio of tensile stress to tensile strain. Measured in pascals (Pa). Materials with high Youn…
Ytterbia
The oxide of ytterbium, Yb₂O₃, a white powder. Like other rare earth oxides, ytterbia is used in making specialized glass and ceramics, as a dopant in various materials, and as a c…
