- Scientists found a new and promising qubit at a place where there is nothing 22/06/2021 In the world of quantum mechanics, researchers can even make empty space, the lack of something, do their bidding. Scientists have now created a new setup to control the absence of electrons in a sol
- Nanomaterials with laser printing 17/06/2021 An interdisciplinary team presents a laser-driven technology that enables them to create nanoparticles out of materials such as copper, cobalt and nickel oxides. At the usual printing speed, photoelectrodes are produced in this way, for example, for a wide range of applications such as the generation of green hydrogen.
- Magnetism drives metals to insulators in new experiment 15/06/2021 Like all metals, silver, copper, and gold are conductors. Electrons flow across them, carrying heat and electricity. While gold is a good conductor under any conditions, some materials have the property of behaving like metal conductors only if temperatures are high enough; at low temperatures, they act like insulators and do not do a good job of carrying electricity. In other words, these unusual materials go from acting like a chunk of gold to acting like a piece of wood as temperatures are lowered. Physicists have developed theories to explain this so-called metal-insulator transition, but the mechanisms behind the transitions are not always clear.

- Emergence of a new heteronanostructure library 03/06/2021 Organizing functional objects in a complex, sophisticated architecture at the nanoscale can yield hybrid materials that tremendously outperform their solo objects, offering exciting routes towards a spectrum of applications. Developments in synthetic chemistry over past decades has enabled a library of hybrid nanostructures, such as core-shell, patchy, dimer, and hierarchical/branched ones.
- New evidence for electron's dual nature found in a quantum spin liquid 01/06/2021 New experiments provide evidence for a decades-old theory that, in the quantum regime, an electron behaves as if it is made of two particles: one particle that carries its negative charge and the other that gives it a magnet-like property called spin. The team detected evidence for this theory in materials called quantum spin liquids.
- Hanging by a thread: Imaging and probing chains of single atoms 27/05/2021 Low-dimensional materials, such as 1D monoatomic chains, exhibit exotic properties that could find interesting applications. However, single-atom bonds and their mechanical characteristics are difficult to study. In a recent study, scientists from JAIST, Japan, showcase a novel method to simultaneously image monoatomic platinum chains with a transmission electron microscope while measuring their bond strength and conductance during mechanical stretching. This technique will help answer many questions in the fields of nanomechanics and surface science.
- Researchers see atoms at record resolution 25/05/2021 In 2018, Cornell researchers built a high-powered detector that, in combination with an algorithm-driven process called ptychography, set a world record by tripling the resolution of a state-of-the-art electron microscope.

- Electromagnetic levitation whips nanomaterials into shape 18/05/2021 To deliver reliable mechanical and electric properties, nanomaterials must have consistent, predictable shapes and surfaces, as well as scalable production techniques. Engineers are solving this problem by vaporizing metals within a magnetic field to direct the reassembly of metal atoms into predictable shapes.
