Scaling down Ionic Transistors to the ultimate limit


Share
The human brain is a vast network of billions of biological cells called Neurons which fires electrical signals that process information, resulting in our sense and thoughts. The ion channels of atomic scale in each neuron cell membrane plays a key role in such firings that opens and closes the ion flow in an individual cell by the electrical voltage applied across the cell membrane, acting as a “biological transistor” similar to electronic transistors in computers. For decades, scientists have learned that biological ion channels are life’s transistors capable to gate extremely fast and precisely selective permeation of ions through the atomic-scale selectivity filters to maintain vital living functions. However, it remains a grand challenge to date to produce artificial structures to mimic such biological systems for fundamental understanding and practical applications. ....

Abstract:
The perfect transmission of sound through a barrier is difficult to achieve, if not impossible based on our existing knowledge. This is also true with other energy forms such as light and heat.

The perfect transmission of sound through a barrier is difficult to achieve, if not impossible based on our existing knowledge. This is also true with other energy forms such as light and heat.
A research team led by Professor Xiang Zhang, President of the University of Hong Kong (HKU) when he was a professor at the University of California, Berkeley, (UC Berkeley) has for the first time experimentally proved a century old quantum theory that relativistic particles can pass through a barrier with 100% transmission. The research findings have been published in the top academic journal ....
