Research

Antimicrobial Applications of Atmospheric Cold Plasma

  • Plasma activated air, water, micro/ultrafine (nano) bubbles, and mist
  • Microbial decontamination
  • Inactivation of microbial biofilms in the processing environment

Agricultural and Environmental Applications of Atmospheric Cold Plasma

  • Seed decontamination and germination improvement
  • Mycotoxin degradation
  • Plasma activated water as a green fertilizer and sanitizer for greenhouse and indoor farming - hydroponics and aquaponics

Sanitation, Disinfection & Cleaning in Food Processing Industry

  • Conventional antimicrobial interventions (e.g., peracetic acid, lactic acid, citric acid, hydrogen peroxide, dry heat, quats)
  • Cold plasma and UV based hybrid treatment development with conventional antimicrobial interventions

Agri-Food Processing & Engineering

  • Low-moisture food safety engineering
  • 3D printability of plant proteins, carbohydrates, and fibers
  • Plant protein and carbohydrate particle formation (gels, powders, emulsions) and functionality improvement (e.g., peas, canola, lentil, faba bean, etc.)
  • Conventional agri-food process intensification and development of novel extraction, homogenization, and drying processes

Wastewater Treatment

  • Atmospheric cold plasma bubble technology development
  • Treatments using ultraviolet and blue light pulses emitted from LEDs
  • Microbial decontamination
  • Degradation of antibiotics and pesticides in wastewater

Micro/Ultrafine (Nano) Bubble Technologies 

  • Microbial biofilm inactivation
  • Water treatment

UV LED applications
