Photothermal therapy

Photothermal therapy (PTT) refers to efforts to use electromagnetic radiation (most often in infrared wavelengths) for the treatment of various medical conditions, including cancer.This approach is an extension of photodynamic therapy, in which a photosensitizer is excited with specific band light. This activation brings the sensitizer to an excited state where it then …

How do supercapacitors work?

How can you store electric charge? Batteries and capacitors do a similar job—storing electricity—but in completely different ways. Batteries have two electrical terminals (electrodes) separated by a chemical substance called an electrolyte. When you switch on the power, chemical reactions happen involving both the electrodes and the …

How Capacitors Work

How Capacitors Work. I like to answer the question of "How does a capacitor work?" by saying that a capacitor works like a tiny rechargeable battery with very low capacity. But a capacitor is usually charged and discharged in a fraction of a second. So it''s not used for the same purpose as a battery.

Understanding Inductors: Principles, Working, and Applications

In DC circuits, inductors are very simple to work with. You can just replace any inductor in a steady-state DC circuit with a short circuit. If you remember that an inductor is, fundamentally, a coil of wire, this should seem rather unsurprising.
