Current aero-engine sealing materials are reaching their operating limit, as manufacturers seek more efficient engines with longer service lives. Even when utilised in optimum conditions, current have inconsistencies performance due to variabilities microstructure, which lead undesirable responses and events. As such, a new generation of is required. Metallic foams one such material, given the ...

The typical large specific surface area and high reactivity of nanostructured porous silicon (nanoPS) make this material very suitable for the development of sensors. Moreover, its biocompatibility and biodegradability opens the way to the development of biosensors. As such, in this work the use of nanoPS in the field of electrical biosensing is explored. More specifically, nanoPS-based devices...

A comparison of the activity mono- and bimetallic Ni-Cr/C catalysts deposited on a carbon carrier (sibunite) in bicyclohexyl dehydrogenation reaction as stage hydrogen evolution storage systems is carried out. The interaction Ni Cr supported onto carrier—sibunite NiCr affects change parameters crystal lattice nickel, compared with FCC Ni, shown by methods XPS, TPR, XRD, high-resolution TEM elec...
