Immunohistological analysis has shown that silicatein exists in the axial canal (axial filament) and on the surface of the spicules, suggesting that they grow by apposition, and it is demonstrated that the enzymic reaction of silicatesin is inhibited by anti-silicatein antibodies.

The present stage of knowledge on structure, biochemical composition, and mechanisms of biosilica formation is reported, focusing particularly on sponges because of the enormous (nano)biotechnological potential of the enzymes involved in this process.
Understanding the Tribochemical Mechanisms of IF-MoS2 Nanoparticles Under Boundary Lubrication
Inorganic fullerene-(IF)-like nanoparticles made of metal dichalcogenides (IF-MoS2, IF-WS2) have been known to be effective as anti-wear and friction modifier additives under boundary lubrication.…

It is demonstrated that a liquid-liquid phase separation occurs at the outset of the precipitation under diffusion-controlled conditions (typical for biomineral formation) with a slow increase of the supersaturation at neutral pH.
Genotoxic effects of zinc oxide nanoparticles.
Evidence is found for the assumption that DNA-DSBs could be caused by Zn(2+) without the involvement of ROS, and a slow increase of ROS after ZnO NP exposure and reduced but not quashed DSBs after NAC-treatment suggest that Zn (2+) may exert genotoxic activities without the necessity of preceding ROS-induction.
V2O5 Nanowires with an Intrinsic Peroxidase‐Like Activity
V2O5 nanowires exhibit an intrinsic catalytic activity towards classical peroxidase substrates such as 2,2‐azino‐bis(3‐ethylbenzothiazoline‐6‐sulfonic acid) (ABTS) and 3,3,5,5,‐tetramethylbenzdine…
Vanadium pentoxide nanoparticles mimic vanadium haloperoxidases and thwart biofilm formation.
It is shown that vanadium pentoxide nanowires act like naturally occurring vanadium haloperoxidases to prevent marine biofouling, and have the potential to be an alternative approach to conventional anti-bioFouling agents.
Ferroelastic Fingerprints in Methylammonium Lead Iodide Perovskite
Methylammonium lead iodide (MAPbI3) perovskite shows an outstanding performance in photovoltaic devices. However, certain material properties, especially the possible ferroic behavior, remain…
