Abstract Background Dentitions have diversified enormously during vertebrate evolution, involving reductions, modifications, or allocations to prey seizing and processing regions. A combination of ancient and novel features related to dental and oropharyngeal apparatuses is found in extant lineages of non‐teleost fishes, such as the gars.

Laser‐Textured Field‐Engineered Interface for Robust Dry‐Processed Cathodes in Lithium‐Ion Batteries
Laser‐patterned dry electrodes applied to current collectors could serve as a promising alternative to the limitations of conventional dry electrodes. Laser technology provides a fast and simple method to enhance the surface roughness of current collectors, improving the adhesion at the electrode–current collector interface.
