Use of Polyethylene Spheres to Study Effect of Microplastics Transport in Soil

Effect on Microplastics Transport

Despite great general benefits derived from plastic use, accumulation of plastic material in ecosystems, and especially microplastics, is becoming an increasing environmental concern. Microplastic has been extensively studied in aquatic environments, with very few studies focusing on soils. Overview of the study on microplastics transport in soil: Scientists tested the idea that microplastic particles (polyethylene … Read more

Fluorescent Glass Microspheres

Fluorescent Red Coated Soda Lime Glass Microspheres

Solid glass microspheres hemispherically coated with fluorescent coatings, a fluorescent coating is precisely applied to half of the core sphere, making the glass spheres appear colorful and fluorescent at daylight and exhibit bright fluorescent response under UV light.

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 … Read more

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 … 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

Deformable Conductive Bondline Spacers – Silver-Coated PMMA Microspheres

PMPMS AG 1 5 125 150um Deformable Conductive Bondline Spacers - Silver-Coated PMMA Microspheres

What are bondline spacers? Microspheres are widely used as bond line spacers because today’s technological advancements are demanding tighter and tighter tolerances.  Assembly of many instruments, especially in electronics, optics, biotechnology, calibration, and medical devices, requires holding precise spacing between parts. Depending on the requirements of the application, a rigid non-flexible bond line may be … Read more
