Accurate Modeling of Viruses – Spherical Particle Shape, Size, and Density

Spherical Particle Shape of Coronavirus from CDC

Spherical Particle Shape of Viruses and Droplets: Due to the global pandemic, there has been a big focus on Coronavirus research and a lot of pressure for researchers and scientists to understand how Coronavirus spreads, as well as how we can effectively stop that spread by implementing effective cleaning protocols, prevention of respiratory droplets traveling, disinfecting of surfaces, or…

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 is d=m/V, where d…

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.

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 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…

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 such as PLGA, polylactic…

Matching the Density of Particle and Fluid for PIV Applications

Product Code: UVPMS-BG-1.00 (Cospheric LLC) Fluorescent Microspheres Precision Density of 1.00g/cc

Density of particle vs. density of fluid in particle image velocimetry: Many flow visualization experiments are done in water but there are a variety of other liquids and even water-based solutions that will have differing densities whose velocity fields are being mapped or will be in the future. Therefore, having seed particles to match these differing densities is important…

Particle Image Velocimetry and Tracer Particle Visibility

Microspheres in Biotechnology - Modeling of Bacteria Behavior

Particle Image Velocimetry (PIV) expresses a vast field with varying techniques and data acquisition methods. However, the main goal is providing an optical method of flow visualization. The exact information obtained depends on which method is used, with new algorithms and approaches being discovered constantly. There are generally two ways data is obtained PIV and Particle Tracking Velocimetry (PTV)…
