[Thin-Films] – Watching the evolution of nanostructures in thin films 7 September 2023

Scientists make extensive use of X-ray fluorescence to map elements in materials. However, this technique does not have the needed spatial sensitivity unless the probe is finely focused.
Scientists have now found a way to turn X-ray fluorescence into an ultra-high position-sensitive probe to measure tiny internal structures called nanostructures in thin films (Nature Communications, “Reconstruction of Evolving Nanostructures in Ultrathin Films with X-ray Waveguide Fluorescence Holography”). These thin films can be a hundred times finer than a human hair.

[Thin-Films] Discovering features of band topology in amorphous thin films 5 September 2023

In recent years, scientists have been studying special materials called topological materials, with special attention paid to the shape, i.e., topology, of their electronic structures (electronic bands). Although it is not visible in real space, their unusual shape in topological materials produces various unique properties that can be suitable for making next-generation devices.

[Innovation] – Codex International now offers the very last SPS sintering technology. 21 March 2023

The main characteristic of Spark Plasma Sintering (SPS) is that the pulsed or unpulsed DC or AC current directly passes through the graphite die as well as the powder compact, in case of conductive samples.

[Nanotechnology] – Novel memristors are based on perovskite nanocrystals. 7 March 2023

In many respects, the human brain is still superior to modern computers. Although most people can’t do math as fast as a computer, we can effortlessly process complex sensory information and learn from experiences, while a computer cannot – at least not yet. And, the brain does all this by consuming less than half as much energy as a laptop.

[Innovation] – Codex International fully committed to “Lead free materials” 24 November 2022

The RoHS concept (Restriction of the use of certain Hazardous Substances) since 2006, requires that many electrical and electronic equipment must no longer contain a concentration by atomic weight of more than 0.1% of Pb, Me, Cr (hexavalent) etc…

[Nano-Technology] – New materials could enable longer-lasting implantable batteries 2 November 2022

For the last few decades, battery research has largely focused on rechargeable lithium-ion batteries, which are used in everything from electric cars to portable electronics and have improved dramatically in terms of affordability and capacity. But nonrechargeable batteries have seen little improvement during that time, despite their crucial role in many important uses such as implantable medical devices like pacemakers.

[Nano-Technology] – Advanced nanoparticles provide new weapon to fight difficult cancers 28 October 2022

Nanoparticles, or tiny molecules that can deliver a payload of drug treatments and other agents, show great promise for treating cancers. Scientists can build them in various shapes with different materials, often as porous, crystal-like structures formed by a lattice of metal and organic compounds, or as capsules that enclose their contents inside a shell. When injected into a tumor, these particles can release treatments that attack cancer cells directly or complement other treatments like immunotherapy and radiation.

[Nano-Technology] – Using chirality for faster, smaller, and more efficient data storage devices 28 October 2022

Researchers at Johannes Gutenberg University Mainz (JGU) are pursuing a completely new and unconventional strategy to improve the way data can be processed and – in particular – stored. Together with their partners at the Hebrew University of Jerusalem, they have been granted funding by the Carl Zeiss Foundation (CZS). The project of this interdisciplinary team is among a total of five projects – all at early stages and considered to be especially innovative – to be funded through the new CZS Wildcard program. The team members, based in Mainz and Jerusalem, have come up with the idea of bringing together two different forms of chirality to develop new data storage systems that are faster, smaller, and more efficient than those currently available.

[Nano-Technology] – Nanoglues stabilize metal atoms for catalysis 26 October 2022

In a study published in Nature (“Functional CeOx nanoglues for robust atomically dispersed catalysts”), a research team led by Prof. ZENG Jie from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences and international collaborators developed a novel “nanoglue” strategy to stabilize atomically dispersed metal catalysts.
