Observing Dynamic Proton-Deuterium Exchange in Microfluidic Systems using Real-Time Infrared Chemical Imaging

Observing Dynamic Proton-Deuterium Exchange in Microfluidic Systems using Real-Time Infrared Chemical Imaging

The need to visualize the dynamic evolution of chemicals mixing and reacting at the microscale is increasing. There are a variety of applications, from controlling the syntheses of drugs in micro-flow channels, to monitoring the uptake of drugs in live cell experiments. [More]
Efficiently and Automatically Detecting Machine Failure Before it Occurs

Efficiently and Automatically Detecting Machine Failure Before it Occurs

The early signs of an imminent breakdown in machinery are often small changes of vibrations that warn of extreme wear on bearings, on which the machinery’s efficient function depends on [More]
The Harm to Health and Productivity Caused by LED Flicker

The Harm to Health and Productivity Caused by LED Flicker

As the use of LEDs becomes more prevalent it is becoming increasingly important that flicker, and it’s associated health hazards, are recognized and measured. However, flicker is a complex phenomenon which makes it difficult to accurately measure. [More]

Measuring and Preventing the Flicker of LEDs – An Interview with Steven Goetstouwers

Steven Goetstouwers is the CEO of Admesy, a company that specializes in the production of spectral measurement systems and colorimeters. AZoM spoke to Steven about the phenomenon of LED flicker, it's unpleasant side effects and the best method for determining its prevalence. [More]
X-ray Diffraction Techniques: Ab Initio Structure Determination Via Powder X-Ray Diffraction

X-ray Diffraction Techniques: Ab Initio Structure Determination Via Powder X-Ray Diffraction

X-ray diffraction is a powerful tool for determining the structure of crystalline materials – this is most often used for identification of unknown samples, such as in geology and earth sciences, or for studying protein structures in life sciences. It can also be used to determine the unit cell dimensions of a known crystal, or to measure the purity of a sample. [More]
What is the Effect of Sample Size on Particle Size Distribution Measurements?

What is the Effect of Sample Size on Particle Size Distribution Measurements?

Particle size distributions are the results generated by the AccuSizer. Rules of statistics govern the properties of the distributions. A vital question when employing a particle size analyzer is how much of a sample has to be measured to correctly define the resultant size distribution. [More]
Effect of Sub-Visible Silicone Oil Droplets on Liquid Particle Counts

Effect of Sub-Visible Silicone Oil Droplets on Liquid Particle Counts

Particulate matter found in injectable drugs is measured in the visible and sub-visible ranges. In the sub-visible range, measurements are generally made by liquid particle counter, or by microscopic analysis of the sample captured on a filter. [More]
Preparing Microbubble Contrast Agents for Ultrasound Image Enhancement

Preparing Microbubble Contrast Agents for Ultrasound Image Enhancement

Microbubbles are key factors in molecular imaging procedures with ultrasound, as they act as a contrast agent by increasing sensitivity between blood and surrounding tissues. Ideally the mircobubbles can be selectively adhered to areas of interest via surface modification. [More]
Testing Solid Particle Filter Efficiency with Liquid Particle Counting

Testing Solid Particle Filter Efficiency with Liquid Particle Counting

The removal of particles from a fluid is known as filtration. One of the common uses of liquid particle counters is to evaluate the efficiency of filters to remove particles of various sizes. [More]
