Erosion characterization of SiC and Ti3SiC2 on DIII-D using focused ion beam micro-trenches

Nuclear Materials and Energy, 2019
Plasma-facing materials in future large-scale fusion reactors must be designed to withstand high heat fluxes from extreme off-normal events such as edge localized modes and unmitigated plasma disruptions.

Tissue‐Stimulator Platform for Electrically Stimulating Pancreatic β‐Cells for Long‐Term Functional Regulation

Advanced Functional Materials, EarlyView.
We present a tissue‐stimulator platform for seamless electrode integration with pancreatic tissue, applying uniform electrical stimulation through optimized design with biohybrid 3D printing. Advantageous effects of electrical stimulation on β‐cell function were observed, including enhanced calcium signaling, islet morphology, and maturation.

Coated Electrode Performance in µEDM of Alloy Steel: A Parametric Optimization Study [PDF]

EPJ Web of Conferences
Micro-Electrical Discharge Machining (µEDM) precisely creates micron-scale holes, vital for components like fuel injectors and nozzles. The process relies on controlled electrical discharges between the tool (typically the cathode) and the workpiece ...

Unlocking Photodetection Mode Switching from a Simple Lateral Design

Advanced Functional Materials, EarlyView.
A simple lateral 2D perovskite photodetector capable of switching among transient, continuous, and dual transient/continuous photoresponse modes is achieved by integrating photoconductive effects with capacitive coupling from the SiO2/Si substrate. Such light‐programmable photodetection mode switching enables triple‐channel information transmission and

Record Energy Storage Performance Metrics in Ferroelectric Hafnia‐Based Films through Heterostructure Design

Advanced Functional Materials, EarlyView.
Dielectric capacitors typically struggle to achieve both high energy storage density and high efficiency at applied voltages below 10 V. Here, we address this challenge by introducing a novel hybrid fluorite/perovskite heterostructure design that combines ultra‐high recoverable energy storage density with efficient energy release (Uf ≈ 1016 J/cm3), at ...

3D‐Printed Hygroscopic Polymer Networks for High‐Humidity Triboelectric Nanogenerators to Wirelessly Power Implantable Electronic Devices‐ A Conceptual Pathway

Advanced Functional Materials, EarlyView.
This work develops 3D‐printable tribopolymer networks that can enhance triboelectric performance under high humidity environments. Polar hydrophilic functional groups and incorporation of zwitterionic monomers promote bound‐water–dominated interfacial polarization thereby increasing electrical outputs.
