High-powered, fast-charging supercapacitors are usually not capable of holding a large amount of energy in a small space. But a new supercapacitor developed at University College London that uses innovative graphene electrode material with…

When a thin layer of alumina is applied to common cathodes, lithium is trapped in batteries. That limits the number of times a battery can be charged and discharged at full power. But new phenomena being studied by engineers at Rice…

A new solution for typical 48 V lighting systems has made its way to the market with the launch of RECOM's new RCDE-48 series LED driver modules with up to 60 VDC input voltage and 1050 mA constant current output with analog or PWM deep…

As the number of chips required to power our devices increases and their size has had to decrease commensurately, finding new methods to fit layers of semiconductors as thin as a few nanometers has become increasingly important.…

One of the reasons it took so long to develop workable lithium-ion batteries for cars was the inherent instability of lithium, especially during charging. Metallic lithium plating that can occur during extreme temperature fluctuations means…

A DC motor is one of the most basic motors you can get, and it helps convert electrical energy to mechanical energy. DC motors are classified into three main sub-types: brushed motors, universal motors, and permanent magnet motors. These…

As our need for battery power increases and the amount of space available to generate and contain that power decreases, ultrathin batteries are in high demand, particularly for use in medical monitoring devices. Recently a scientific…

Two new UnitedSiC devices are offering designers more powerful performance. The new products offer RDS(on) values of 30mohms (UF3C065030T3S) and 80mohms (UF3C065080T3S). The three-leaded, industry-standard TO220-3L package features…

The answer is: Zombies. Working to figure out how to keep decomposing molecules from shortening the overall lifespan of an organic aqueous flow battery, Harvard University researchers discovered that creating zombies is the answer.…

With more than 3% of power generated worldwide devoted to maintaining data storage, our need for more energy-efficient ways to store data grows exponentially as the amount of data we want to store increases. Traditionally, data is…
