Dear Visitor!

[Download article: Modeling the heat effect of ultrasound in the irradiated tissues]

My name is Dr. Attila Lőrincz and I am active ultrasound specialist. Please allows me that I introduce me and my activity.

Qualification: PhD (Ultrasound Physics and Biology)
Chemical and Bioengineer
Food Engineer

Activity: Design, construction and salesmanship of active (?1W/cm2) ultrasound systems and devices

Settlement: Research and Development / know-how and/or device salesmanship

Enterprise: Design, building and salesmanship of general and special ultrasound devices and systems from laboratory to plant size

Main cooperation fields:

- ultrasonic cell and particle disruption
- acoustical cutting, surface treatments (liquid and dry type)
- solid phase transmission of high performance vibration
- acoustical mixing (molecular and batch),
- acoustical homogenizing, and dispersion (emulsifying, suspending)
- acoustical sedimentation, emulsifying/emulsion dissociation
- defoaming
- acoustical levitation (in liquids and gases)
- ultrasonic vaporization
- industrial cleaning (e.g. textile, membrane, waste water, layer scaling...)
- selective separation
- intensifying of the meat curing, and salting
- acoustical reactor techniques
- hyperthermia
- intensifying of physical, chemical and biological (e.g. fermentation) processes
- continuous supercritical extraction by ultrasound
- other R + D fields.


Developed US systems and devices:

- Ultrasonic tube reactors (20kHz-2MHz);
- Liquid and air base ultrasound levitators (goal: christall enlargement, contact less particle /cell/ manipulation…)
- Design, construction and application of special (20kHz-4MHz) ultrasound transducers (application: in liquid and solid phase)
- Simultaneous treatment-measurement system
- High performance ultrasonic baths and mobile immersible transducers
- Industrial layer scaling equipment
- US disruptors
- new type of ultrasonic homogenizer
- US hyperthermia system (under construction for medical tumour treatment)
- many other special ultrasonic equipments parts and accessorial elements.
