Recent years have seen major breakthroughs in how vaccines and antiviral drugs are formulated and manufactured. Nanoemulsions and liposomes are now widely used as vaccine and drug carriers because they can easily incorporate lipophilic (in the case of nanoemulsions) and hydrophilic (in the case of liposomes) bioactive compounds, stabilize substances that otherwise undergo hydrolysis, and significantly reduce side effects of potent drugs. For the past 14 years, Industrial Sonomechanics (ISM) has been conducting R&D and supplying its scalable ultrasonic technology to many companies in this field, including those using it in ultrasonic vaccine production and, more recently, in the development of SARS-CoV-2 (novel coronavirus) vaccines and/or treatments of the associated COVID-19 disease. This article describes some of the challenges faced by commercial-scale manufacturers of vaccines and antiviral medications and explains how our technology contributes to overcoming them.

Cannabis Concentrates: Medical Significance and Extraction Methods

The cannabis (marijuana, hemp) plant has been used for medicinal purposes for millennia.  In addition to terpenes and flavonoids, over 100 types of therapeutically active compounds known as cannabinoids have been identified in these plants [1]. The two most important and well-known cannabinoids are tetrahydrocannabinol (THC) and cannabidiol (CBD) [2]. Cannabinoids have the ability to directly and/or indirectly affect receptors in our cells because they mimic endocannabinoids produced by our own bodies endogenously, for example, in response to injury [3].

Acoustic Cavitation: The Driving Force Behind Ultrasonic Processing

Liquids exposed to high-intensity ultrasound can undergo acoustic cavitation. This phenomenon can typically be seen as a cloud of bubbles forming in the vicinity of the ultrasonic source (e.g., ultrasonic horn) and heard as an intense hissing noise. Cavitation is the formation of low-pressure voids (a.k.a., vacuum bubbles or cavities) in the liquid, which grow, briefly oscillate and then asymmetrically implode with great intensity.

6 Frequently Used Terms in Ultrasonic Processing of Liquids

[fa icon="calendar'] Dec 1, 2015 4:39:00 PM / by Alexey Peshkovsky, Ph.D. posted in Ultrasonic Processing Systems, Theory of Ultrasonic Processing, Extraction

This blog post focuses on six common terms used in conjunction with ultrasonic processing: ultrasonic amplitude, power, frequency, power intensity, power density and processing rate.

Whether you use ultrasonic processing for making nanoemulsions, milling pharmaceutical crystals, degassing, extracting botanical oils, manufacturing bio-fuels, dispersing pigments, disrupting cells or enhancing a chemical process, there are several general terms you need to be familiar with. Knowing these terms and keeping track of the corresponding parameters will insure reproducibility of results and simplify process-related discussions with your peers.
