Ultraviolet-B (UV-B) semiconductor lasers are highly sought for medical, biotechnology, and precision manufacturing applications; however, previous UV-B laser diodes were limited to pulsed operation ...

Abstract: Active front-end boost rectifiers can replace the uncontrolled diode bridge rectifiers for ac–dc conversion offering high power quality with near unity power factor. The four-switch, B4, ...

Abstract: Solid-state transformers (SSTs) are conventionally based on a multistage architecture, with an input and/or an output ac/dc converter (for interfacing with the ac grid and/or the load), and ...

For switching high-powered loads from a microcontroller, or for switching AC loads in general, most of us will reach into the ...

Superconducting devices are electronic devices that harness the zero-resistance properties of superconductors. Superconducting devices are used for highly sensitive optical sensors, detectors of ...

Organic LEDs are light emitting diodes (LEDs) that use polymers or small organic molecules as their optically active element. Development of organic LEDs is driven in particular by its potential as a ...

The Income Tax Department has introduced a new online feature on its e-filing portal, allowing taxpayers to directly file rectification requests for specific tax orders with the relevant authority.
