Many applications require DC/DC conversion. So many, that it is estimated that the world market will exceed 35 billion dollars by 2020. But for many circuit designers, the DC/DC converter is a “black ...

AMI (alternate-mark inversion) is a three-level—positive, zero, negative—copper-cable transmission code with the useful property of having no dc component for ease of ac coupling using capacitors or ...

“For the first time, this strategy allows us to efficiently and precisely create a structural motif that was previously difficult to access,” says Friedmann. Specifically, the chemists have discovered ...

Establishment and maintenance of apico-basal polarity in epithelial organs must be tightly coupled with cell division, but the underlying molecular mechanisms are largely unknown. Using 3D cultures of ...

Adding charge pump and LDO components to a boost converter circuit creates a cost-effective power supply for LCDs and other portable applications. Many portable devices use LCD displays. These ...

Researchers at Leipzig University have developed a new process for reversing the polarity of chemical compounds, also known as umpolung, for the precise synthesis of pharmaceuticals. This innovative ...
