Thermal transport in a highly porous metallic wire-woven bulk Kagome (WBK) is numerically and analytically modeled. Based on topology similarity and upon introducing an elongation parameter in thermal tortuosity, an idealized Kagome with non-twisted

At a density lower than 10 −1 g/cc, Microlattice and Nanolattice become vulnerable and tend to fail because of the early local buckling concentrated at the connections between the hollow trusses that compose them. In contrast, a Shellular, in the f

We introduce a new type of auxetic material with ultrahigh strength and ductility that mimics the crystal structures of two natural solids: α-cristobalite and LaNiO3/SrTiO3 superlattice (or ABO3 perovskite). The fabrication method is based on wire-w

Thermofluidic behaviors governing the enhanced cooling performance of the wire-woven-bulk diamond (WBD) cored brake disc in comparison with the conventional pin-finned brake disc used on heavy vehicles were characterized experimentally. For each type

Recently, insect-mimicking micro-drones have attracted attention owing to their numerous potential applications. For use as the exoskeletons of these micro-drones, a monolithic sandwich panel with a total thickness of 1 mm was fabricated in this stud

Microlattice is the most advanced version of truss cellular materials with ultralow density and high mass productivity, thanks to the mask-based lithography. However, its structure lacks in-plane truss elements, which results in low structural stabil

In this study, a novel concept of polymer scaffold was proposed based on 3D porous membrane architecture. It had two distinct sub-volumes intertwined with each other but separated by a single continuous smooth semi-permeable membrane. One sub-volume

We introduced a novel technique to fabricate a Microlattice-cored miniature sandwich panel with an ultralow density. This sandwich panel was made of a monolithic Ni-P foil without any bonding between the core and the faces. As a preliminary study, th

In this paper, a novel actuator in the form of a Kagome truss composed of shape memory alloy (SMA) wires and common metallic wires is described. In the actuator, the SMA wires play dual roles as load supporters and actuating elements. The intersectio
