Additive and Laser Manufacturing for Multifunctional Electronics on High‐Performance Polymers

open access: yesSmall Science, EarlyView.
Highly conductive laser‐induced graphene (LIG) is scribed by a low‐power blue laser on additively manufactured (AM) polyetherimide and polyether ether ketone. Functional and sensing LIG electronics are investigated through Joule heaters and strain gauges, which operate reliably under high thermal and mechanical stresses.

Folding Competition and Dynamic Transformation in DNA Origami: Parallel Versus Antiparallel Crossovers

open access: yesSmall Methods, EarlyView.
This dynamic DNA origami features two rotational panels that can be designed into two major configurations using either antiparallel crossovers (AX) or parallel crossovers (PX). Through competitive folding processes, 36 pairs of designs with different key staples are studied, and a bidirectional isothermal transformation is demonstrated, providing ...
