In lab tests, the anode-free sodium battery hit a critical current density above 20 mA cm⁻² and supported charging rates of 10C — meaning minutes instead of hours. The cells still held more than 70% ...

A new study from UNC School of Medicine researchers, published this week in Neuron, reveals a unique look at how junk food ...

Former Lions QB Dan Orlovsky did not like what he saw from Detroit's offense in Week 1's ugly loss against Green Bay.

Abstract: This paper briefly reviews several circuits of white light LED driving structure, which includes the voltage regulator and current limiting resistance model, current regulator and current ...

Abstract: We are almost always surrounded by light from LEDs in organic LED (OLED) TV screens and active-matrix OLED displays in mobile phone screens. LEDs are everywhere, in workplaces, headlamps, ...

A new solution deposition process for semiconductors yields high-performing transistors by introducing more defects, counterintuitively. Researchers used these devices to construct high- speed logic ...

We all carry supercomputers in our pockets and use dozens of electric gizmos every day but rarely stop to marvel at the magical act of flicking a switch. Use your ordinary conducting and extraordinary ...

AC LED driver circuits are overly popular due to the advancement of High current white LEDs. We already made a Transformerless LED driver circuit previously, but in that circuit, we used a dedicated ...

In this project, we're making a cool 4×4×4 LED cube with Arduino Nano. LED cubes, also known as LED Matrix, can light up your room, study space, or Maker area giving it a awesome cool look. Moreover ...
