In 1917 Harold Arnold and IB Crandall of the American Telephone and Telegraph Company and Western electric Company showed that they could create sound by simultaneously passing alternating and direct currents through a very thin platinum foil.

The device wirelessly converts the microwave signal to direct current voltage capable of recharging a cell phone battery or other small electronic device according to a report appearing in Applied Physics Letters.

The researchers will also test the method in high-voltage cables for direct current, since direct current is more efficient than alternating current for power transmission over very long distances c

#Arming nanoparticles for cancer diagnosis and treatment UCD researchers have manipulated successfully nanoparticles to target two human breast cancer cell lines as a tool in cancer diagnosis and treatment.

A small direct current (DC) is created when due to the rectifiers switching on and off at record speeds on the petahertz scale.

for example, be used to rectify alternating current to direct current, and so these types of diodes are known as rectifiers.

and uses inverters to turn direct current into grid-ready alternating current, presents them with a serious set of challenges.

electronic circuitry in the computer's power supply converts the AC oscillations into direct current (DC) that the device can use.

which combines an antenna's function of receiving electromagnetic waves with a rectifier's function of outputting direct current.

and off at record high petahertz speeds, creating a small direct current. Billions of rectennas in an array can produce significant current,

Power inverters convert direct current into the alternating current that powers the vehicle. The Oak ridge inverter achieves much higher power density with a significant reduction in weight and volume.

Each charging station will come with two Level 2 chargers that can charge vehicles in several hours plus one Direct current

because they can be used to create devices that produce direct current or to drive chemical reactions on otherwise inert metal surfaces.

reportedly harvests the electromagnetic radiation transferring to and from mobile phones and converts it into direct current (DC) electrical energy,

The energy of the radio waves the router sent out was converted into direct current voltage with a component called a rectifier,

whether it contained actual data or the aforementioned power traffic into direct current voltage, which was boosted then to a usable voltage with a DC-DC converter.
