Depth‐Customizable 3D Electrode Array for Recording Functional Connectivity in the Brain

open access: yesAdvanced Electronic Materials, EarlyView.
In this study, a depth‐adjustable, flexible 3D multi‐shank electrode array that produces precise neural recordings at various brain depths is developed. Integrating 2D flexible electrode arrays with a modular supporting board allowed the insertion depth to be easily adjusted without re‐fabrication.

Breaking Barriers: Centimeter‐Sized Single Layer WSe2 by Gold‐Mediated Exfoliation for Ambipolar Field Effect Transistors at Ultra‐Low Voltages

open access: yesAdvanced Electronic Materials, EarlyView.
2D transition metal dichalcogenides (TMDCs) are promising for next‐gen electronics. In this work, centimetrer‐sized single‐layer WSe2 is achieved via thermally activated gold‐mediated exfoliation. When integrated into solid‐state electrolyte gating field‐effect transistors, the devices exhibit ambipolar behavior, steep subthreshold swings down to 30 mV

Impact of Transition Metals and Electrocatalyst Layer Thickness on the Pt‐Based Cathodes of Proton Exchange Membrane Fuel Cells – Do Multimetallic Electrocatalysts Necessarily Yield an Improved Performance?

open access: yesAdvanced Energy Materials, EarlyView.
Nonnoble transition‐metals (TMs) in PtCuNi/C catalysts have a dual influence in proton‐exchange membrane fuel cell cathode catalyst layer. While TMs act as a “sacrificial component” of PtCuNi/C, inhibiting Pt dissolution from the PtMx nanoparticles bearing the active sites, they promote the formation of separate catalysts and ionomer domains in the ...
