Additively manufactured hierarchical stainless steels with high strength and ductility : Nature Materials : Nature Research
hierarchically heterogeneous microstructure stainless steal via 3D cellular structures seems to be better than bulk stainless. Made using a conventional laser powderbed fusion 3D printer.

Material heterogeneity in cancellous bone promotes deformation recovery after mechanical failure
So soft surface but brittle interior type bones seem to guide cracks into structurally insensitive areas to maintain strength under failure/deformation.

Monolithic graded-refractive-index glass-based antireflective coatings: broadband/omnidirectional light harvesting and self-cleaning characteristics - Journal of Materials Chemistry C (RSC Publishing)
So, new surface coating technique that uses nanostructures to achieve a superhydrophobic effect, rather than polymer or powder surface coating, that is also much more abrasion resistant. Also conveniently antireflective.

High-strength cellular ceramic composites with 3D microarchitecture
Research into 3D printed microstructure honeycombs/truss, which get plated with alumina to make tremendously strong but light materials. Uses a german NanoScribe for the 3D printing.

Claiming a new processing style for bainitic steels yields a new microstructure substantially improving the properties of steel to the point that it outperforms some aluminum and titanium alloys at substantially lower cost. Also, at the time of discovery, it was 7% stronger than any other steel alloy and could be made in 10 seconds of treatment.
