Exceptional Thermal Conductivity in Printed Dielectrics through Compositional and Microstructural Design

open access: yesAdvanced Materials, EarlyView.
A multi‐generational compositional design creates a printable low‐loss dielectric composite that achieves over 16 W m−1 K−1. This breakthrough is enabled by thermal post‐processing, which promotes templated crystallization in a polymer matrix from surface‐modified particles, creating a “hetero‐percolated network.” The resulting material is three ...

Heterogeneous Nanopore Arrays – Selective Modification of Nanopores Embedded in a Membrane

open access: yesAdvanced Materials, EarlyView.
Biological processes rely on the concerted action of channels with different functionalities embedded in the same membrane. Inspired by nature, heterogeneous nanopore arrays are prepared where two nanopores are connected in parallel and function as two different elements of an ionic circuit: a diode and a resistor.
