Reduced power consumption in semiconductor devices

Stepping stones are placed to help travelers to cross streams. As long as there are stepping stones that connect both sides of the water, one can easily get across with just a few steps. Using the same principle, a research ...

Solving the mystery of ultralow-voltage LEDs

Light-emitting diodes (LEDs) have created far-reaching impacts on display and lighting industries. For a LED to emit light, the minimum voltage is widely considered to be equal to the bandgap voltage of the material, in consideration ...

New membrane improves reversibility of zinc-air batteries

The long-standing challenges to the practical implementation of rechargeable zinc-air batteries (ZABs) are the electrochemical irreversibility of the Zn anode and degradation of the air cathodes in alkaline electrolyte, which ...

Logical switching using one single molecule

Logic gates, the basic elements of the digital world, can now be built using one single molecule. An example is XOR, with two inputs. If at least one of them is "1," then the output is "1," as well; otherwise, it is 0. These ...
