10 Years Development of Potassium‐Ion Batteries

open access: yesAdvanced Materials, EarlyView.
Significant progress is made in PIBs over the past decade, but the improvements based on half‐cell testing, low mass loading, and low energy density are insufficient for practical applications. This review summarizes the challenges and strategies for PIBs, highlights the importance of further research focusing on full cells, and provides an analysis of

Machine‐Learning‐Aided Advanced Electrochemical Biosensors

open access: yesAdvanced Materials, EarlyView.
Electrochemical biosensors are highly sensitive, portable, and versatile. Advanced nanomaterials enhance their performance, while machine learning (ML) improves data analysis, minimizes interference, and optimizes sensor design. Despite progress in both fields, their combined potential in diagnostics remains underexplored.

Microwave Interferometry Based On Open-ended Coaxial Technique for High Sensitivity Liquid Sensing

open access: yesAdvanced Electromagnetics, 2017
This paper describes a modified open-ended coaxial technique for microwave dielectric characterization in liquid media. A calibration model is developed to relate the measured transmission coefficient to the local properties of the sample under test.

Scaling Up Purcell‐Enhanced Self‐Assembled Nanoplasmonic Perovskite Scintillators into the Bulk Regime

open access: yesAdvanced Materials, EarlyView.
This study presents a scalable approach to enhancing bulk scintillators using nanoplasmonics. By integrating 100‐nm silver nanoparticles with perovskite scintillator nanocrystals in a polymer matrix, significant improvements in light yield and decay rates via the Purcell effect are achieved.

Optimization techniques for permittivity and permeability determination

open access: yesJournal of Research of the National Institute of Standards and Technology, 1991
This paper discusses optimization techniques for the determination of complex permittivity and permeability in transmission lines. The traditional theoretical model using scattering parameters is extended into a mathematical regression model that can be solved with widely accepted numerical techniques.

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 ...
