Intracrystalline Void‐Mediated Toughening of Brittle Crystals in Quail Eggshells
Advanced Functional Materials, EarlyView.In quail eggshells, the high density and disordered arrangement of intracrystalline voids inhibit lattice cleavage, suppress long‐range crack propagation, and promote deformation twinning and quasi‐plasticity, serving as an essential toughening motif. We show that these voids remain within a narrow subcritical size range and therefore predominantly do ...

Advanced Functional Materials, EarlyView.Trinuclear iron oxo‐bridged catalytic ensembles stabilized by aspartic‐acid‐derived carbon dots provide an effective platform for alkaline oxygen evolution. Mixed‐valence charge balancing, inner‐sphere charge transport, and work‐function alignment within the N/O‐rich carbon framework promote cooperative Fe‐site chemistry and efficient OER ...

A modified offset cutter path strategy for high-speed rough milling hardened steel
, 2003 Previous work has shown that the use of an offset cutter path strategy when high-speed rough milling hardened steel using an axial depth of 15 mm resulted in the lowest tool life as compared to the use of raster and single-direction raster strategies [1]

Integrated method for tool path generation in five-axis sculptured surface machining [PDF]
, 2011 Five-axis machining allows continuous adjustment of cutter orientation along a tool pass. Unfortunately, the flexibility has not been fully exploited due to the separate consideration of tool path generation and cutter orientation in current machining ...
