“…For instance, by applying template-assisted dielectrophoretic assembly, Xu et al accurately placed Au nanoparticles on the gaps of adjacent electrodes (Figure a), which greatly facilitated the fabrication and integration of electrically driven plasmonic light-emitting devices (Figure b,c) . Moreover, Ding et al utilized a superplastic nanomolding technique to fabricate a single-crystalline aluminum nanowire in a scalable and cost-effective manner (Figure d), which showed high stability and outstanding waveguide properties for subwavelength light splitting, routing, and optical information encryption (Figure e) …”

In Situ Nanomechanics: Opportunities Based on Superplastic Nanomolding

“…Meanwhile, in order to conduct controlled experiments on nanorods with identical diameters, such as investigating the impact of annealing temperature and time, ordered AAO templates are preferred in the SPNM process, which can produce ordered and uniform metal nanorod arrays (Figure S3). Beyond in situ nanomechanics, this SPNM technique can also serve as the basis for broad applications of mechanical loading, namely the active regulation of the physical/chemical properties of 1D nanostructures, which brings a feasible tool for interdisciplinary fields. − Therefore, by combining the SPNM technique with in situ nanomechanics, cutting edge interdisciplinary researches as well as diverse applications can be envisioned (Figure ).…”
