Treating infections organized in biofilms is a challenge due to the resistance of the pathogens against antibiotics and host immune cells. Many fungi grow in a wet environment, favorable for the growth of bacterial biofilms, and we speculated that fungi possess some strategies to control these bacterial biofilms. A fungus identified as Hypoxylon fragiforme, was collected in the Harz Mountains, ...

As an analogy to nickel-based superalloys, ferritic superalloys based on Fe-Al-Cr-Ni-Ti are proposed for high-temperature applications, especially for fossil-energy power systems. Integrated computational tools will be employed to investigate thermodynamic, kinetic, and meso-scale properties of the proposed alloy systems. Meanwhile, selected microstructural attributes in representative model fe...
