Local Polarization Unit Engineering Enables Ultrahigh Energy Density in NBT‐Based High‐Entropy Ceramic Capacitors

open access: yesAdvanced Science, EarlyView.
Herein, we demonstrate a breakthrough in dielectric energy storage by engineering local polarization units in high‐entropy multilayer ceramic capacitors (MLCCs). The optimized MLCCs achieve an ultrahigh recoverable energy density of 18.2 J cm−3 with 91% efficiency, coupled with exceptional thermal stability and fatigue resistance.

The Case for Philosophy of Chemistry [PDF]

open access: yes, 1997
The philosophy of chemistry has been sadly neglected by most contempory literature in the philosophy of science. This paper argues that this neglect has been unfor-tunate and that there is much to be learned from paying greater philosophical attention to

An Embodied Paper‐Based Microfluidic Al‐Air Battery for Enduring Untethered Insect‐Scale Robots

open access: yesAdvanced Science, EarlyView.
This work presents a centimeter‐scale microfluidic aluminum–air battery (MFAAB) with dual‐surface anode and F−‐mediated byproduct decomposition. The design enables a high capacity of 2697.05 mAh/g Al and delivers tens of milliwatts to power LEDs, motors, and a toy car.

Instrumental Rationality and Naturalized Philosophy of Science

open access: yes, 2012
In two recent papers, I criticized Ronald N. Giere's and Larry Laudan's arguments for 'naturalizing' the philosophy of science (Siegel 1989, 1990). Both Giere and Laudan replied to my criticisms (Giere 1989, Laudan 1990b).

An Energy Autonomous Microneedle Array‐Based Sensing System for Continuous Biomarker Monitoring

open access: yesAdvanced Science, EarlyView.
This work presents an innovative self‐powered wearable biosensor system for real‐time monitoring of multiple biomarkers in interstitial fluid. The device integrates stainless steel‐based minimally invasive microneedles with ion‐selective membranes, enabling simultaneous Na+, K+, Ca2+, pH, and glucose detection.
