A demilune table is a semi-circular table which is designed to be pushed up against a wall. Demilune tables come in a wide range of styles which are intended to complement various home decorating schemes, and they are also fairly easy to make in a home woodworking shop, for people who want to create a very specific and desired look.
The serous demilune is an artifact from traditional methods of preparing samples. Samples are traditionally preserved and fixed in formaldehyde. When samples were preserved by quick-freezing in liquid nitrogen and then fixed with osmium tetraoxide in acetone, no demilunes are found.he serous demilune is an artifact from traditional methods of preparing samples.
