Bioinspired nanofilament coatings for scale reduction on steel.

Scaling of steel surfaces, prevalent in various industrial applications, results in significant operational inefficiencies and maintenance costs. Inspired by the natural hydrophobicity of springtail (Collembola) skin, which employs micro- and nanostructures to repel water, we investigate the application of silicone nanofilaments (SNFs) as a coating on steel surfaces to mitigate scaling. Silicone nanofilaments, previously successful on polymers, textiles, and glass, are explored for their hydrophobic properties and stability on steel.

H Consumption by Various Acetogenic Bacteria Follows First-Order Kinetics up to H Saturation.

Acetogenic bacteria play an important role in various biotechnological processes, because of their chemolithoautotrophic metabolism converting carbon dioxide with molecular hydrogen (H) as electron donor into acetate. As the main factor limiting acetogenesis is often H, insights into the H consumption kinetics of acetogens are required to assess their potential in biotechnological processes. In this study, initial H consumption rates at a range of different initial H concentrations were measured for three different acetogens.

Hyperoxia and unfavourable outcome in patients with non-traumatic subarachnoid haemorrhage: A systematic review and meta-analysis.

Background: It is common practice to administer oxygen to neurocritical patients in the Intensive Care Unit (ICU). Consequent hyperoxia has been associated with unfavourable outcomes including in patients with brain injury, after cardiac arrest, sepsis, and traumatic brain injury. The aim of this systematic review was to explore the association between hyperoxia exposure and unfavourable outcome in patients following a non-traumatic subarachnoid haemorrhage (SAH).
