Source: Yong P. Chen, PhD, Department of Physics & Astronomy, College of Science, Purdue University, West Lafayette, IN Electric potential, also known as "voltage", measures the electric potential energy per unit charge. Electric field is a scalar quantity and is fundamental to many electrical effects. Like potential energy, what is physically meaningful is the difference in the electric potential. For example, the spatial variation in the electric potential is related to the electric...

Robert M. Rioux & Suprita Jharimune, Pennsylvania State University, University Park, PA Among the many hazards present in the laboratory, electrical hazards are one of the most common we must be cognizant of since most of the laboratory equipment we use requires electricity for operation. Improper handling or operation of electrical devices might lead to electric shock with the potential risk of injury or even death. Electric sparks can lead to fire or explosion (since many flammable...

Source: Yong P. Chen, PhD, Department of Physics & Astronomy, College of Science, Purdue University, West Lafayette, IN An electric field is generated by a charged object (referred to as the source charge) in the space around it, and represents the ability to exert electric force on another charged object (referred to as the test charge). Represented by a vector at any given point in the space, the electric field is the electrical force per unit test charge placed at that point (the force...

Gene transfection by electroporation is improved approximately two times when orientation of electric field is changed during pulse application, while cell viability is not affected. The increase in gene transfection is caused by the increase of the membrane area which is made competent for DNA entry into the cell.
FAQs
At the photovoltaic stage, light excites a semiconductor and creates charge carriers that can produce electrical current. Chemistry helps researchers examine how the semiconductor material supports this conversion and how material choices affect cell performance. This focus connects the light-to-electricity step with efforts to improve solar cells as sustainable technologies.
Different renewable systems convert energy through different physical and chemical pathways. Turbines first turn motion from wind or flowing water into rotation, whereas electrochemical systems convert chemical energy into electron flow. Comparing these pathways helps distinguish where chemistry is most central, particularly in redox reactions, catalysts, solar-cell materials, batteries, and fuel systems.
Variable supply makes energy storage an important part of renewable electricity research. Batteries and fuel systems provide chemical routes for storing or converting energy, while redox reactions describe electron-transfer processes involved in electrochemical operation. Catalysis can also support these systems by improving chemically driven transformations, helping researchers address changing availability from renewable sources.
A chemistry-focused investigation can examine the materials used in solar cells, the redox reactions underlying electrochemical systems, and the role of catalysis in fuel systems. Researchers can then connect these chemical features to energy conversion or storage performance. This approach supports targeted improvement of solar cells, batteries, fuel systems, and methods for managing variable supply.
When renewable generation is variable, batteries and fuel systems become relevant because they address the challenge of managing changing energy availability. Their study brings chemistry into system design through electron-transfer reactions, materials, and catalysis. Research in these areas can help connect renewable generation with more resilient energy systems rather than treating generation as an isolated process.
Chemistry contributes to sustainability research by improving the materials and reactions used in solar cells, batteries, and fuel systems. These improvements support technologies that can reduce reliance on finite fuels and lower emissions. At the broader system level, combining renewable generation with storage and supply-management approaches can contribute to resilient energy systems and ongoing sustainable-technology research.
