3 Scenarios When Density of Microspheres Matters in Research

Does Density of Microspheres Matter for Fluid Suspension?

When is the density of microspheres important? Density of microspheres controls the buoyancy of each particle and its behavior in a system or process. Let’s look at three scenarios: (1) suspension of microspheres in a specific fluid, (2) fluid flow, performing flow visualizations, or particle image velocimetry, and (3) simulation or modeling of objects with specific density.

Are Microplastics Toxic to the Environment? Literature Review

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 the size, shape, and…

Particle Dispersion Experiments in Plant Canopies

UV Fluorescent Microspheres

Fluorescent Microspheres in Particle Dispersion Experiment Fluorescent microspheres produced by Cospheric LLC were used as part of ongoing work to to conduct particle dispersion experiments in plant canopies and study the mechanisms of fungal epidemiology in vineyards. The University of Utah in collaboration with USDA Labs in Corvallis, OR performed five field particle dispersion campaigns in commercial vineyards in…

Janus Particles – Properties and Applications

Bichromal (half-white half-black or any other color) Microspheres, Janus Particles

What are Janus Particles? Named after two-faced Roman god Janus who looks to both the future and the past, Janus particles are typically microscopic spheres composed of two different regions. Originally the term “janus particles” was used in reference only to particles that had a hydrophobic surface on one hemisphere and a hydrophilic surface on another. The first “Janus…

Microspheres Simulate Contamination in Self-Cleaning Gecko-Inspired Adhesives

Image of Self-cleaning Adhesive of Gecko's Toes

When choosing a controlled tracer particle for process development and troubleshooting, there are many benefits when microspheres simulate contamination. Colored and fluorescent microspheres provide a highly visible marker of controlled size and shape, allowing scientists and engineers to observe and troubleshoot the process in order to best understand where the contamination is coming from, develop best protocols for preventing…

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 the Journal of The…

Deformable Silver Coated PMMA Microsphere Spacers

PMPMS AG 1 5 125 150um 480x480 Deformable Silver Coated PMMA Microsphere Spacers

Silver Coated Glass Microspheres work well for increasing the conductivity of bond lines, but they lack the capability to deform when compressed to give increased conductive contact between the surfaces of the bond line.? These newly released Silver Coated PMMA Microspheres offer the low weight deformable pmma cores, and 250nm thick silver coating for high conductivity. Conductivity of this…
