Scientists have designed the world's smallest all-digital phase-locked loop (PLL). PLLs are critical clocking circuits in virtually all digital applications, and reducing their size and improving their performance is a necessary step to enabling the development of next-generation technologies.
This new human blood-brain barrier on a chip gets its surprising edge by giving astrocytes 3D living space.
Superconductors are regarded as promising components for quantum computers, but so far they only function at very low temperatures. Scientists now demonstrated a so-called energy quantization in nanowires of high-temperature superconductors.
Scientists non-invasively released antitumor drug from polymer containers modified with iron oxide nanoparticles inside primary cancer cells.
A material shaped like a one-dimensional DNA helix might further push the limits on a transistor's size. The material comes from a rare earth element called tellurium.
Researchers have developed a flexible ionic conductor that is water-processable and thermal stable.
An international team of researchers has revealed new insights into the workings of a lithium battery by virtually 'unrolling' its coil of electrode layers using an algorithm designed for papyrus scrolls.
