Melt Electrowriting of Poly(dioxanone) Filament Using a Multi‐Axis Robot
Macromolecular Materials and Engineering, Volume 307, Issue 12, December 2022., 2022 For the first time, a medical polymer called poly(dioxanone) is processed using melt electrowriting. This is achieved using a filament‐feeding system that differs from the more common pressurized air approaches. Mounting this type of print head onto a multi‐axis robot with a spherical collector results in nonplanar MEW structures.

Assembly or Optimized C for Lightweight Cryptography on RISC-V?
, 2020 A major challenge when applying cryptography on constrained environments is the trade-off between performance and security. In this work, we analyzed different strategies for the optimization of several candidates of NIST’s lightweight cryptography standardization project on a RISC-V architecture.

Advanced Electronic Materials, EarlyView.In this study, by employing the flash‐thermal reduction (FTr) technique, the reduction degree of the graphene oxide (GO) with systematic analyses of conductivity and material stability is precisely adjusted. The optimized FTrGO‐based sensor exhibits exceptional flexibility, reversibility, high sensitivity (≈1.28% °C−1), excellent linearity (R2 ≈ 0.999),
