Are Microplastics Toxic? Effects of Microplastics on the Environment

What are microplastics? Microplastic (MP) is a broad term used to describe microscopic plastics with sizes ranging from 1um to 5mm 1. 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 spheres2. The properties such as … Read more

Silica Nanospheres as Photonic Nanostructure Found in the ‘Disco’ Clam Ctennoides Ales

Silica Nanospheres in a disco’ or ‘electric’ clam Ctenoides ales

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

Monodisperse Silica Nanospheres and Microspheres – Dry Powder

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.

ParaMagnetic Microspheres

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.

Dual nanocomposite multihollow polymer microspheres prepared by suspension polymerization based on a multiple pickering emulsion

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.
