While working at GE on various projects related to his doctoral thesis and the
Mössbauer effect, Berger also did research on
polymer chemistry and
Cherenkov radiation. He later worked at Espey Manufacturing and Electronics Corporation where he began to work deeply in the field airflow, thermal dynamics, and combustion.
Ultrasonic Atomization Berger based his work on ultrasonic atomization first from the work of
John William Strutt, 3rd Baron Rayleigh and his
capillary waves in liquid as they relate to the frequency of vibration, imposed and on that of Robert J. Lang whose published experiments involved atomizing melted wax and cooling and collecting the resultant small beads which he could measure. Lang's work showed a direct correlation between the sizes and the frequency of the vibrations that produced them. In 1973 and 1974 Berger was working to counter the effects of the
1973 oil crisis, believing that the advantages of ultrasonic spray would make heating a building more efficient; an idea for which he later file and received one of his many US Patents on a design of an
ultrasonic nozzle. By the time Berger and his team had worked out a viable commercial design, the woes of oil crisis had passed and he set out to find the right applications for his new technology. In addition to the many patents Berger was granted for his work , , et al., he was published and cited in many technical journals such as his introduction of the technology to The International Conference on Liquid Atomization and Spray Systems Berger "wrote the book" on the subject matter and published Ultrasonic Liquid Atomization, Theory and Application in 1998. Being the father of the application of the technology, Harvey Berger was frequently called to speak on the matter and write publications regarding its benefits in certain applications, such as medical applications and more specifically the coating of
drug-eluting stents. ==References==
