Engineered Nanotopography to Modulate Growth and Signaling of Neuronal Networks
Advanced Functional Materials, EarlyView.This study examines the interaction between neurons and nanoscale topographies on engineered substrates. Neurons cultured on nanowires, nanopillars and nanoneedles exhibit enhanced neurite outgrowth, form more organized neuronal circuits, and display improved synaptic connectivity, compared to flat substrates.

High‐Speed Photoresponse of CVD‐Grown Lateral TMD Heterostructures
Advanced Functional Materials, EarlyView.Internal electric fields generated by p‐n junctions and asymmetric Schottky barriers enhance the photoresponse speed in CVD‐grown monolayer TMD lateral heterostructures. This results in a 1.5‐2 orders of magnitude reduction in rise and fall times for optimized device configurations compared to homogeneous single‐material devices, enabling bandwidths ...
