A Kinetic Framework for the Pyrolysis of Poly(Ether‐Ketone‐Ketone) (PEKK)

open access: yesJournal of Applied Polymer Science, EarlyView.
Crosslinking influences poly(ether‐ether‐ketone) (PEKK) pyrolysis. ABSTRACT Research to date on the thermal degradation of poly(ether‐ketone‐ketone) (PEKK) has largely been limited to low temperatures or analysis as part of a composite. Herein, we investigate the pyrolysis kinetics of neat PEKK from 480°C to 1000°C and characterize the degradation by ...

Surface Properties of CeB6 and Challenges in Surface Preparation Revealed by Scanning Tunneling Microscopy

open access: yesAdvanced Physics Research, EarlyView.
The investigation of the Kondo lattice system CeB6${\rm CeB}_6$ by highly surface sensitive techniques is hampered by difficulties in preparing well‐ordered, atomically flat surfaces. The richness of possible surface terminations and their impact on spectroscopic STM results are discussed.

A Review of Transient Characterization Techniques for Quantum Dot Light‐Emitting Diodes

open access: yesAdvanced Physics Research, EarlyView.
This review surveys transient characterization techniques for quantum dot light‐emitting diodes, including TRPL, TREL, TA, and E‐TA. These methods resolve carrier‐selective dynamics across multiple time scales, enabling direct analysis of charge injection, exciton formation and recombination, efficiency roll‐off, and device degradation.
