What are microplastics? Microplastic (MP) is a broad term used to describe microscopic plastics with sizes ranging from 1um to 5mm1. Anything less than that can be considered nanoplastic (NP), which is also prevalent in the ocean. The shapes of microplastics can vary from fragments, fibers, pellets, film, and spheres((Luís Carlos de Sá, Miguel Oliveira, … Read more
Silica Nanospheres in a Photonic Display Scientists from University of California at Berkeley have recently discovered that a strange naturally occurring bright display of the ‘disco’ or ‘electric’ clam Ctenoides ales is actually a photonic display created by a layer of silica nanospheres. The display functions solely by reflecting light. Their article was published in … Read more
Silica nanoparticles and nanospheres are now available in distributions of less than 10% CV in the sizes of 0.25 micron, 0.5micron, 0.75 micron, 1.0 micron, 4 micron and 8 micron.
These highly spherical polyethylene microspheres offer the flow-ability of standard microspheres, with the ability to be separated from other materials for re-use and cleanup.
Excerpts from an interesting approach to creating hollow polymer microspheres from a pickering emulsion.
Abstract:
A solid-stabilized multiple w/o/w or o/w/o emulsion was prepared in a two-step process. Various nanocomposite polymer microspheres with multihollow armored closed pores were fabricated easily by suspension polymerization of the multiple Pickering stabilized emulsions.
We are compiling a digital database on everything that has to do with microspheres and creating a destination for scientists working with precision spherical particles.
