Ultrasonography

Ultrasonography

Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called a...

Upstream Processing

Upstream Processing

Upstream processing represents a critical phase in biomanufacturing, wherein biological systems such as microorganisms, mammalian cells, or insect cells are cultivated to produce therapeutic proteins, vaccines, enzymes, or other biologically derived products. This phase encompasses all steps from the selection and genetic manipulation of the production organism to the cultivation of cells in bioreactors under tightly controlled environmental conditions.Host Selection and Genetic OptimizationThe...

Downstream Processing

Downstream Processing

Downstream processing begins once fermentation is complete and involves a series of steps to recover and purify products such as acids, vitamins, antibiotics, or proteins.Cell HarvestingFor example, for intracellular protein-based products, the first step is harvesting the cells. This is typically achieved using centrifugation or filtration to separate the cells from the liquid phase.Cell Disruption for Intracellular ProductsIf the target product is intracellular, the harvested cells must be...

Background:

High-power ultrasonics (HPU) is a green technology with vast industrial potential.
Limited commercial applications exist due to a lack of suitable large-scale transducers.
Existing transducers often lack the power capacity, efficiency, and adaptability for diverse industrial needs.

Purpose of the Study:

Introduce a new family of HPU transducers with extensive radiators.
Address limitations in power capacity, efficiency, and radiation pattern control.
Facilitate broader industrial adoption of HPU technology.

Main Methods:

Design and development of HPU transducers with adapted radiators for specific applications.
Incorporation of strategies to mitigate nonlinear behavior and modal interactions.
Evaluation of transducer performance in fluid and multi-phase media.

Main Results:

New HPU transducers offer high power capacity, high efficiency, and controlled radiation patterns.
Designs effectively reduce modal interactions common in high-power operation.
Successful implementation in semi-industrial and industrial processes across various sectors.

Conclusions:

The new HPU transducers overcome previous limitations for large-scale applications.
These advancements are driving the development of HPU in food, environmental, and manufacturing industries.
The characterized transducers represent a significant step towards broader HPU industrial integration.
