Reducing The Surface Friction Of Medical Devices - A New Functional Application For A Commercial Biomaterials Surface Modification Technology
By Alexandra Piotrowicz, Manager of Product Development, Surface Modification, Evonik Health Care
As the number of minimally invasive surgeries continues to grow, there is a need to design low-profile devices with optimal surface properties for easy insertion and trackability.  Devices such as introducer sheaths, delivery catheters, endoscopes, and neurovascular microcatheters come in contact with various bodily fluids and tissue, including skin, blood vessels, and the urinary tract.  The surface design of such devices should aim to minimize trauma during insertion and removal, reduce tissue inflammation, enable maneuverability through tortuous blood vessels, and improve patient comfort.  Furthermore, surface properties should promote smooth movement between certain dev ....

Nanocomposite-Based Method to Create Highly Efficient Solar Cells


Nanocomposite-Based Method to Create Highly Efficient Solar Cells
Written by AZoNanoFeb 3 2021
A new technique to develop unique solar cells could considerably enhance their efficiency. Apart from being made of thin layers, the cells also include nanoblocks that are specifically arranged.
This schematic representation shows the new structure: nickel oxide stripes run perpendicular to the actual material, serving as a passing lane for the electrons. Image Credit: Lutz Mühlenbein.
This has been demonstrated by an international team of researchers led by the Martin Luther University Halle-Wittenberg (MLU), in a new study published in
Nano Letters, a scientific journal.
Solar cells available in the market are chiefly made of silicon. “ ....
