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.

Does Particle Shape Matter? Roundness and Sphericity

Measuring Roundess of Microsparticles

Does Shape of Microparticles Matter? Particle shape plays a critical role in how the particles travel, behave, interact with each other and their environment. It also influences particle flow characteristics. Flow characteristics (ball-bearing effect) of spherical particles: Spherical shape of microparticles is often desirable because spheres and microspheres are well-known for their ball-bearing effect. They … Read more

Significance of Density of Powders: Bulk Density vs. True Particle Density

Density of Powder - How to Measure Accurately

What is the density of material? Before we start talking specifically about measuring the density of powders, let’s look at the concept of measuring density in general. What does “density” mean? According to Encyclopedia Britannica, density is defined as mass of a unit volume of a material substance. The formula for density of a substance … Read more

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 … Read more

Suspension of Hydrophobic Particles in Aqueous Solution – Density Gradients

Hydrophobic Particles in Solution

Fortunately, there is a simple way to overcome the hydrophobic effect. It is called a surfactant, a detergent, or simply ?soap.? Surfactant is a magical molecule that has both hydrophobic and hydrophilic properties, which coats the particles and helps them mix into water. The same mechanism applies when we use soap to wash greasy dishes or stained clothes.

Particle Dispersion Experiments in Plant Canopies

UV Fluorescent Tracer 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 … Read more

Microspheres in Drug Delivery Systems – 2 Essential Uses

Polystyrene Microspheres

Benefits of Microspheres in Drug Delivery There are numerous benefits of using microspheres in drug delivery due to their precise uniform dimensions, larger surface area per unit volume, as well as the ability to be surface-functioalized or loaded with active compounds and other additives. Typically microspheres in drug delivery are manufactured out of biodegradable materials … Read more
