A step for spintronicsA technology known as spintronics is already used to some extent in devices like computer memory and sensors. The number of devices and applications based on spintronics is anticipated to grow in the future, as the technology is fast with low power consumption and enables new innovations like quantum computing. Spintronics builds
The Swedish Research Council (Vetenskapsrådet, VR), which funds most of MAX IV operations, performed their first operation review on 7–8 May 2024. The six previous reviews by the council since 2018 have been project reviews of a facility under construction. This review was the first of the facility in full operation. On 20 May, the Panel briefed
Electromigration and failureCopper is the most commonly used material for connecting transistors on a chip. The current being pushed through the tiny copper wires cause a phenomenon called electromigration. Electromigration is a form of mass transport driven by the flow of electrons, where atoms migrate from one end of the copper structure to the other,
Energy can be stored by separating negatively and positively charged atoms or molecules, ions, of a substance, called an electrolyte. Liquid electrolytes are found in, for example, batteries or supercapacitors. Salts contain negative and positive ions and, for example, table salt, sodium chloride, contains positive sodium ions and negative chloride ions but has a melting
Microgels consist of polymers that are crosslinked and forms a ball somewhat resembling a tiny ball of yarn. The connections of the polymer is initiated by adding a cross-linking agent. A larger amount of cross-linking agent results in a more tightly-knit ball. The polymer can also be functionalised to be sensitive to for example temperature
“The particles are synthesised in a new way that is fast and simple without chemicals that would be hazardous to the environment. They could potentially be made from biomass in the future as part of the Circular Economy. They are bio-compatible and can be recovered and re-used after the water has been cleaned,” says Alejandro
A recent publication from Uppsala University reported a world record for efficiency for a CIGS solar cell. Nano X-ray Fluorescence imaging was done at beamline NanoMAX. With this method, the researchers can detect which elements are present in the sample on the nanometre scale. By scanning the sample, they can acquire an image with a
Carbon dioxide can be converted into methanol and water by reaction with hydrogen. The reaction is only possible in the presence of a catalytic material such as Au or Cu nanoparticles supported on zinc oxide. The chemical reaction will then take place on the particle surfaces. In a recent study, a research team from Germany,
Cuprates are materials based on copper oxide that are well-known model systems in which the electrons interact strongly with each other. Because of this interaction, they exhibit several unusual phenomena, including so-called unconventional superconductivity, where the necessary electron pairs are conjectured not to be held together by lattice vibrations but by interactions between electrons themselves.
“We eat too little fibre for optimal health today both in Sweden and the rest of the world. We’re trying to help that by making a product that can be used in foods to increase the fibre content without compromising taste and texture,” says Annelie Moldin from Lantmännen. Fibre-rich foods might not get chosen as
