[Graphene] – Large-scale synthesis of graphene and other 2D materials 7 September 2023

Since its first demonstration in 2004, the large-scale commercial production of graphene has proven difficult and costly (‘large scale’ usually defined as weights more than 200 mg or films larger than 200 cm2). For instance, at an estimated cost of $50 000 to $200 000 per ton for graphene powders and $45 000 to $100 000 per m2 of graphene film, industrial production methods and costs are restraining graphene utility.

[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] – Researchers test quantum theory with precision-engineered thin films 5 September 2023

Comparing experimental results and theoretical calculations can be difficult for quantum materials. These are materials that have special properties, such as superconductivity, that can only be understood using the rules of quantum mechanics. One way that scientists compare experiments and computations is to use sample materials that isolate and emphasize an atomic line with one dimensional (1D) properties.

[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.
