Summary A variety of different methods exist for gathering three-dimensional information for micro- and nanoscale objects. Tilting of samples in a scanning electron microscope provides a non-destructive way of generating these data. Traditionally, th

A linear-to-rotary motion converter is demonstrated using 3-D SiGe/Si dual-chirality helical nanobelts (DCHNBs). Analytical and experimental investigation shows that the motion conversion has excellent linearity for small deflections. The conversion
