Here, we demonstrate that this challenge can be overcome by architecting a gradient structure featuring a surface layer of nacre-like nanolaminates followed by multi-variant twinned structure in pure titanium. The polarized accommodation of highly regulated grain boundaries in the nanolaminated layer to ...
Here we introduce a gradient structure in commercial pure titanium utilizing the ultrasonic surface rolling process (USRP) technique31,32(Fig.1and Methods). We achieved a gradient structure featuring a surface layer (<200 μm in depth) of nacre-like nanolaminated (or so-called “brick-and-mo...
Nacre is generally regarded as tough body armor, but it was often smashed by predators with a certain striking speed. Nacre-like architectures have been demonstrated to dissipate abundant energy by tablets sliding at static or specific low-speed loads, b

Barthelat et al. fabricated a complex architecture based on nacre, with ordered 3D designs and interlayers made of a transparentthermoplasticelastomer to the manufacture of impact-resistant laminated glass[41]. The resulting transparent, nacre-like glass sheet had only a slight lower light transmission...

Inspired by natural columnar nacre, artificial montmorillonite/hydroxyethyl cellulose columnar nacre-like materials with a site-specific layered structure in the interior and a hierarchical columnar structure on the surface are prepared. The materials exhibit improved tensile strength, good chemical stability...
o Progressive and p brittle fracture surface. Reproduced with permission48 Full size image Recently, a 1D graphene-PVA fiber with a nanoscale nacre-like brick-and-mortar structure and microscale twisting was successfully fabricated by Kotov et al.48. They developed a shear-induced self-assembly ...
