Enhancing Specific Stiffness of Nano‐Architected Materials Through Generative AI and Active Learning

open access: yesAdvanced Science, EarlyView.
A structure‐centric generative framework searches voxelated design space directly, coupling a variational autoencoder with multi‐objective optimization and active learning to progressively expand the validated design domain. The discovered nano‐architectures, realized as pyrolytic carbon by two‐photon lithography, deliver 18–23% higher stiffness and 26–

3D Bioprinted Blood–Brain–Tumor Barrier Spheroid‐Based In Situ Evaluation of Anticancer Compounds Against Glioblastoma: ROS‐Producing Ruthenium as a Potential Therapeutic Candidate

open access: yesAdvanced Science, EarlyView.
The blood–brain–tumor barrier (BBTB) penetration by anticancer drugs and their effects on glioblastoma (GBM) is assessed using 3D bioprinted‐spheroids. Anticancer drug‐induced U‐87 MG cell death is quantified through in situ imaging of spheroids using a cancer cell death probe. The Ru compound, a partial P‐gp substrate, induces greater tumor‐cell death

High‐Efficiency InGaP‐on‐Insulator Microresonator Nonlinear Conversion and Entanglement Generation

open access: yesAdvanced Science, EarlyView.
Sulfur treatment of InGaP‐on‐Insulator (InGaP‐OI) significantly reduces surface roughness, passivates surface states, and lowers propagation loss at visible wavelengths, enabling efficient nonlinear frequency conversion and photon‐pair generation.

Snapshot Spatiotemporal‐Spectral Imaging Enabled by Joint Photonic Encoding

open access: yesAdvanced Science, EarlyView.
Spectra4D enables snapshot spatiotemporal‐spectral imaging by combining high‐speed DMD temporal modulation with CMOS‐integrated Fabry‐Pérot spectral encoding. From a single 2D measurement, a dual‐mask‐guided reconstruction network recovers multiple time‐resolved hyperspectral frames, enabling high‐fidelity observation of rapidly evolving spatial ...
