When a pulse of light reflects from a mirror that is travelling close to the speed of light, Einstein’s theory of relativity predicts that it will be up-shifted to a substantially higher frequency and ...

This article explains the reason why so many manufacturers need to measure particle size and the reason behind laser diffraction being the method of choice. Different industries measure particle size ...

A targeted way to manipulate beams of protons accelerated using ultrashort and ultraintense laser pulses has been demonstrated by a team of researchers. A targeted way to manipulate beams of protons ...

What is Particle Size Analysis? Particle size analysis is a technique for determining the particle size distribution in a material. Solid materials, emulsions, suspensions, and even aerosols may all ...

Ultrashort laser pulses—that are shorter than a millionth of a millionth of a second—have transformed fundamental science, ...

The particle size of the fat droplets present in dairy and other food emulsions is important in defining properties such as flavor release, mouth feel and the emulsion stability. Large emulsion ...

The collective response of charged particles to intense fields is intrinsic to plasma accelerators and radiation sources, relativistic optics and many astrophysical phenomena. Here we show that a ...

Stuart Wakefield, Regional Manager – Middle East, and India/ Director – Malvern Aimil Instruments (India) in the article reviews the use of laser diffraction and automated imaging coupled with ...

Some published articles purport to demonstrate the difficulties and problems of the laser diffraction technique without mentioning that these apparent problems are inherent in all particle-sizing ...

Experiments were conducted to establish a laser diffraction-based method for the determination of lactose powder particle size. This was accomplished using a Bettersizer 2600 equipped with a fully ...

Particle size defines the performance of a wide range of different products, including cement, paints, inks, metal powders, cosmetics, foods and drinks. Measuring relevant particle size data is ...
