New liquid crystals allowing directed transmission of electricity synthesized
Liquid and solid – most people are unaware that there can be states in between. Liquid crystals are representative of one such state. While the molecules in liquids swim around at random, neighboring molecules in liquid crystals are aligned as in regular crystal grids, but the material is still liquid.

According to Einstein, light consists of particles (photons) that transfer only quantized energy to the electron of the atom. If the photon's energy is sufficient, it knocks the electrons out of the atom. But what happens to the photon's momentum in this process? Physicists are now able to answer this question. To do so, they developed and constructed and new spectrometer with previously unattainable resolution.

Physicists have created a quantum material that can travel through a previously unexplored region marked by strange electronic properties. The journey is by an alloy of cerium palladium and aluminum.
Read moreCurved nanochannels allow independent tuning of charge and spin currents
To increase the efficiency of microchips, 3D structures are now being investigated. However, spintronic components, which rely on electron spin rather than charge, are always flat. To investigate how to connect these to 3D electronics, physicists have created curved spin transport channels. They discovered that this new geometry makes it possible to independently tune charge and spin currents.

Borophene has a nearly perfect partner in a form of silver that could help the trendy two-dimensional material grow to unheard-of lengths.
Read moreScientists finally find superconductivity in place they have been looking for decades
Scientists prove a well-known model of material behavior applies to high-temperature superconductors, giving them a new tool for understanding how these materials conduct electricity with no loss. Simulations suggest we might be able to toggle superconductivity on and off in certain materials by tweaking their chemistry so electrons hop from atom to atom in a particular pattern – as if hopping to the atom diagonally across the street rather than to the one next door.
Read moreScientists one step closer to a fully functioning quantum computer
Quantum computing has the potential to revolutionize technology, medicine, and science by providing faster and more efficient processors, sensors, and communication devices. But transferring information and correcting errors within a quantum system remains a challenge. Researchers now demonstrate a new method of relaying information by transferring the state of electrons. The research brings scientists one step closer to creating fully functional quantum computers.

Contact lenses that can monitor your health as well as correct your eyesight aren't science fiction, but an efficient manufacturing method has remained elusive. Until now. Researchers have reported developing a new manufacturing method to produce the lenses, solar cells and other three-dimensional curvy electronics.

Hey, physicists and materials scientists: You'd better reevaluate your work if you study iridium-based materials — members of the platinum family — when they are ultra-thin. Iridium 'loses its identity' and its electrons act oddly in an ultra-thin film when interfaced with nickel-based layers, which have an unexpectedly strong impact on iridium ions.
