Researchers develop a porous nickel-modified graphene fiber that enhances energy density, conductivity, and durability in ...

A dielectric barrier discharge (DBD) in atmospheric pressure air was excited by a high-voltage pulse power supply. Capacitors with different capacitance were connected in the discharge circuit and ...

A method for analyzing the magnetic field in a capacitor-discharge impulse magnetizer is established by modifying the finite element method. The effects of charging voltage, capacitance and resistance ...

Self-discharge is an important parameter to measure in manufacturing. Finding the right method to make this measurement involves understanding the cause of self-discharge and the science behind ...

For as versatile and inexpensive as switch-mode power supplies are at all kinds of different tasks, they’re not always the ideal choice for every DC-DC circuit. Although they can do almost ...

A team of McGill University researchers, working with colleagues in the United States and South Korea, has developed a new ...

Electrochemical capacitors, also called supercapacitors, store energy using either ion adsorption (electrochemical double layer capacitors) or fast surface redox reactions (pseudo-capacitors ...

In situ polymerization in a covalent organic framework boosts lithium-ion conduction in solid polymer electrolytes, advancing ...
