Advanced Materials, EarlyView.Elephant‐skin‐inspired crack networks are programmed in porous diatomaceous earth (DE)‐cement composites using substrate‐guided, stress‐concentration induced fracture. The resulting crack lattices act as capillary conduits that redistribute water, while the porous matrix stores moisture.

Design of coupled slider crank mechanism for orbiting motion [PDF]
, 2015 The paper describes development of a novel orbiting mechanism. Target design is a shaking mechanism with a planar figure eight closed loop. Shaking dynamics depends on a cycling frequency as well on a reciprocating displacement.

Advanced Materials, EarlyView.Mechanically origami‐coded 3D kirigami photovoltaics convert a single extension–release cycle into deterministic self‐folding, reconfiguring planar solar cells into programmable 3D modules. Distinct coding strategies enable either ultrahigh stretchability (500% system strain) or ultrahigh initial effective areal coverage (225%).
