Tailoring Gel Polymer Electrolytes for Advancing Quasi‐Solid‐State Batteries

open access: yesAdvanced Materials Interfaces, EarlyView.
A UV‐curable gel polymer electrolyte featuring a PEGDA/PEGMA crosslinked network is developed for quasi‐solid‐state lithium batteries. Tuning the curing time enables enhanced ionic conductivity, Li⁺ transference, and interfacial stability, leading to stable lithium plating/stripping and long‐cycle performance in both half and full cells.

Wide‐Field Bond Quality Evaluation Using Frequency Domain Thermoreflectance with Deep Neural Network Feature Reconstruction

open access: yesAdvanced Materials Interfaces, EarlyView.
In this work, wide‐field (>1 mm2) frequency‐domain thermoreflectance (FDTR) hyperspectral imaging is used to image subsurface indium bump bonds 50 µm below the surface. Thermal analysis with Monte Carlo uncertainty propagation is used to evaluate bump quality, while a trained deep neural network (can rapidly reconstruct bump geometry contact area maps.

Experimental Study of Gas Microbubbles on Oil‐Infused Wrinkled Surfaces

open access: yesAdvanced Materials Interfaces, EarlyView.
Microbubbles are observed on both superhydrophobic (SHS) and lubricant‐infused surfaces (LIS) immersed to gassed water. The bubbles on LIS are stabilized by the lubricant cloaking layer, while bubbles on SHS shrink vertically over the same time frame.

Electrochemically‐Assisted Low Power Density Laser Writing on Stainless Steel via Enrichment of Chromium Oxides

open access: yesAdvanced Materials Interfaces, EarlyView.
This research describes the invention of a new method to color the surface of stainless steel with brown to blue hues at micron resolution using a low‐power laser. This method is safer and lower cost than previous methods. The study determines that the main coloring compound is chromium oxide.
