Nanodiamonds as photocatalysts

ScienceDaily.com: Nanotechnology News - 18 октября, 2018 - 19:52
Diamond nanomaterials are considered hot candidates for low-cost photocatalysts. They can be activated by light and can then accelerate certain reactions between water and CO2 and produce carbon-neutral 'solar fuels'. The EU project DIACAT has now doped such diamond materials with boron and shown at BESSY II how this could significantly improve the photocatalytic properties.

Extremely small magnetic nanostructures with invisibility cloak imaged

ScienceDaily.com: Nanotechnology News - 18 октября, 2018 - 17:53
In novel concepts of magnetic data storage, it is intended to send small magnetic bits back and forth in a chip structure, store them densely packed and read them out later. The magnetic stray field generates problems when trying to generate particularly tiny bits. Now, researchers were able to put an 'invisibility cloak' over the magnetic structures. In this fashion, the magnetic stray field can be reduced in a fashion allowing for small yet mobile bits.

Taking steps toward a wearable artificial kidney

ScienceDaily.com: Nanotechnology News - 17 октября, 2018 - 18:10
There just aren't enough kidney transplants available for the millions of people with renal failure. Aside from a transplant, the only alternative for patients is to undergo regular dialysis sessions to clear harmful cellular waste from their bodies. Now, scientists report a new urea sorbent that could accelerate progress toward the development of a lightweight, wearable artificial kidney with the potential to make dialysis more convenient, comfortable and effective.
