ESCRT III Regulates Lysosomal Perinuclear Clustering by Inhibiting Kinesin 1 Leading to Agnps Cytotoxicity in Human Cells

Advanced Materials Interfaces, EarlyView.
AgNPs cause significant damage upon entering the lysosomes of human fibroblasts, resulting in lysosomal transport disorders and the occurrence of perinuclear clustering (LPC) of lysosomes by promoting apoptosis that is accompanied by a reduction in the expression levels of ESCRT III and Kinesin 1 proteins.

Fabricating Mass‐Producible High‐Performance Metaholograms Using Sol‐Gel‐Processed TiO2

Advanced Materials Interfaces, EarlyView.
Mass production of metaholograms on 6‐in. glass is achieved through nanoimprint lithography. TiO₂ sol‐gel is used as an imprint resist, exhibiting a high refractive index in the visible region. Through heat treatment at 600 °C, TiO₂ gel crystallizes into the anatase phase, allowing the fabrication of high‐resolution images with high optical efficiency.

A Flexible‐Substrate 5‐µm‐Diameter Needle Electrode: Minimizing Neuronal Death and Enabling Year‐Long Neural Recording

Advanced Materials Interfaces, EarlyView.
An electrophysiological recording technology that uses a 5‐µm‐diameter microneedle electrode device is presented. Due to the remarkable small dimension of the microneedle, the electrode provides minimal invasive neural recording in a mouse brain and enables long‐term recording exceeding the year‐long duration.

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

Advanced 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.

Locking in Color: Stable RGB Perovskite Nanocrystal Films via UV Cross‐Linking

Advanced Optical Materials, EarlyView.
Combining block copolymer stabilized lead halide nanocrystals with a UV light‐based cross‐linking procedure yields ultra‐stable nanocrystal thin films, which are resistant to dissolution by organic solvents and impervious to interlayer ion exchange. This allows for the fabrication of stacked layer RGB all‐perovskite white light‐emitting phosphors with ...
