The dynamic energy of plasma is shown in this picture. Plasma is an ionized gas that contains charged particles. Plasma, also present in stars, lightning, and cutting-edge technology, is playing a crucial role in areas like medicine, environmental science, and food processing.
In my research, I work at the intersection of plasma chemistry, and its application, symbolized by the energetic flow captured in the plasma glow. I focus on generating plasma-activated solutions (PAS) and applying them as fine mist for disinfection and surface treatment. This novel method leverages reactive species produced in cold plasma, which are known for their antimicrobial properties. By carefully optimizing plasma parameters and mist characteristics, I aim to develop a system that maximizes efficacy while remaining gentle on materials or biological surfaces. Through experimentation, I aim to better understand the chemical mechanisms at play within plasma-treated mists and optimize their use in real-world applications. This image represents not just the visual energy of plasma, but the scientific potential embedded within its reactive nature a field where fundamental science meets meaningful impact.
Was your image created using Generative AI?
No.
How was your image created?
The image was taken in the lab during demonstration of how plasma works with the help of a digital camera. To enhance the quality further processing was done in photoshop software 2024.
Where is the image located?
AFood Safety and Sustainability Lab, University of Alberta, during demonstration of plasma.
