Which Joe gave his name to ‘sloppy joes’? We look at five interesting sandwiches and their lexical origins.
(of a crystal) showing different colours when viewed from different directions, or (more generally) having different absorption coefficients for light polarized in different directions.
- ‘Visual pigments, the molecules in photoreceptors that initiate the process of vision, are inherently dichroic, differentially absorbing light according to its axis of polarization.’
- ‘One common laboratory technique - the use of circularly polarized light in circular dichroic spectroscopy - optically records changes in protein secondary structure to study the dynamics within the biological system.’
- ‘Upon measuring the absorbance of a labeled peptide at a given angle of incidence, two different dichroic ratios were obtained.’
- ‘The light reflected by this dichroic mirror, is split into two separate paths with a polarizing beam splitter.’
- ‘The angle between the diglucosamine ring plane and the membrane plane was determined by dichroic measurements using polarized IR light with oriented multilayers of the endotoxins.’
Mid 19th century: from Greek dikhroos (from di- twice + khrōs colour) + -ic.
