Dielectric barrier discharge (DBD) is a type of electrical discharge that occurs between two electrodes separated by an insulating dielectric barrier, typically used to generate non-thermal plasmas at atmospheric pressure. This process is widely applied in ozone generation, surface treatment, and pollution control due to its ability to produce reactive species efficiently without excessive heat generation.

Dielectric Barrier Discharge

Electrical discharge is the release and transmission of electricity through a medium, often occurring when the electric field strength exceeds the dielectric strength of the medium. This phenomenon can result in visible effects such as sparks or lightning and is a critical consideration in the design of electrical systems to prevent damage or hazards.

Electrical Discharge

An insulating dielectric barrier is a non-conductive material that prevents the flow of electric current while allowing electric fields to interact across it. It is crucial in capacitors, electrical insulation, and various electronic applications to enhance performance and safety by preventing short circuits and energy loss.

Non-thermal plasmas

Atmospheric pressure is the force exerted by the weight of the air above a given point, typically measured in units like Pascals or millibars. It plays a crucial role in weather patterns and can affect human activities, such as aviation and outdoor sports, due to its impact on air density and oxygen availability.

Atmospheric Pressure

Ozone generation refers to the process of producing ozone (O3), a molecule composed of three oxygen atoms, typically through electrical, chemical, or ultraviolet methods for various applications like air purification and water treatment. While beneficial in controlled environments, ozone generation can pose health risks if not properly managed, as ozone is a potent oxidizing agent and respiratory irritant.

Ozone Generation

Surface treatment refers to the processes applied to the surface of a material to enhance its properties, such as corrosion resistance, adhesion, or appearance. These treatments can involve mechanical, chemical, or physical methods to modify the surface characteristics for specific applications.

Surface Treatment

Pollution control refers to the measures and strategies implemented to reduce or eliminate the release of pollutants into the environment, thereby minimizing their harmful impacts on ecosystems and human health. It encompasses a range of techniques and regulatory policies aimed at managing waste, emissions, and contaminants across air, water, and soil mediums.

Pollution Control

Reactive species are highly reactive molecules that can cause significant damage to cells and tissues, but also play essential roles in cell signaling and homeostasis. They include free radicals and non-radicals, and their balance is crucial for maintaining health and preventing diseases such as cancer and neurodegeneration.

Reactive Species

Heat generation refers to the process by which energy is converted into thermal energy, often as a byproduct of mechanical, electrical, or chemical processes. Understanding heat generation is crucial for optimizing energy efficiency and managing thermal conditions in various systems and devices.
