Improving the thermal stability and dielectric properties of epoxy/phenolic resin type (novolac) composites by incorporating carbon nanofibers (CNFs)

open access: yesJournal of Nigerian Society of Physical Sciences
This study aims to enhance the thermal stability and dielectric properties of an epoxy/phenolic resin-type novolac blend by incorporating carbon nanofibers (CNFs). The EP/novolac-CNF composite was created by dispersing a 10% weight fraction of CNFs into

Approaching the Monolayer Limit of Carbon Layers by Pyrolysis of Polymer Films

open access: yesAdvanced Electronic Materials, Volume 12, Issue 3, 4 February 2026.
Wafer‐scale functional devices based on pyrolyzed photoresist films are synthesized directly on target substrates without catalysts or transfer steps, with channels reaching the monolayer limit (0.34 nm). X‐ray photoelectron spectroscopy confirms predominant sp2 character, Raman spectroscopy reveals evolving nanocrystallinity, and transmission electron

Depth‐Customizable 3D Electrode Array for Recording Functional Connectivity in the Brain

open access: yesAdvanced Electronic Materials, Volume 11, Issue 13, August 20, 2025.
In this study, a depth‐adjustable, flexible 3D multi‐shank electrode array that produces precise neural recordings at various brain depths is developed. Integrating 2D flexible electrode arrays with a modular supporting board allowed the insertion depth to be easily adjusted without re‐fabrication.
