Oasis is a trademarked name for wet floral foam, the spongy phenolic foam used for real flower arranging. [3] It soaks up water like a sponge and acts both as a preservative to prolong the life of the flowers and a support to hold them in place.
Floral foam is a piece of dense foam that holds moisture and keeps flowers in place. Most floral foam has a specific container that can hold the foam without anything more than placing it into the container. However, floral foam can be cut into any shape, and therefore placed in any container. [19]
Sphere packing finds practical application in the stacking of cannonballs. In geometry, a sphere packing is an arrangement of non-overlapping spheres within a containing space. The spheres considered are usually all of identical size, and the space is usually three-dimensional Euclidean space.
In geometry, the Weaire–Phelan structure is a three-dimensional structure representing an idealised foam of equal-sized bubbles, with two different shapes. In 1993, Denis Weaire and Robert Phelan found that this structure was a better solution of the Kelvin problem of tiling space by equal volume cells of minimum surface area than the previous best-known solution, the Kelvin structure.
Syntactic foam, shown by scanning electron microscopy, consisting of glass microspheres within a matrix of epoxy resin. Syntactic foams are composite materials synthesized by filling a metal, polymer, [1] cementitious or ceramic matrix with hollow spheres called microballoons [2] or cenospheres or non-hollow spheres (e.g. perlite) as aggregates.
Hollow spheres of other materials create syntactic foams with different properties: ceramic balloons e.g. can make a light syntactic aluminium foam. [ 3 ] Hollow spheres also have uses ranging from storage and slow release of pharmaceuticals and radioactive tracers to research in controlled storage and release of hydrogen . [ 4 ]
