Microplate Active Migration Emerging From Light‐Induced Phase Transitions in a Nematic Liquid Crystal

open access: yesAdvanced Functional Materials, EarlyView.
A quasi‐2D, light‐absorbing platelet embedded in a thermotropic nematic liquid crystal is activated with light irradiation. Depending on the light intensity, the platelet induces a localized nematic‐isotropic phase transition that triggers the motion. Using different confinements, the platelet can glide in a 2D regime or tilt and glide in a 3D regime ...

Vision Transformer for Contrastive Clustering

open access: yes
Vision Transformer (ViT) has shown its advantages over the convolutional neural network (CNN) with its ability to capture global long-range dependencies for visual representation learning. Besides ViT, contrastive learning is another popular research topic recently. While previous contrastive learning works are mostly based on CNNs, some recent studies

Flux‐Regulated Crystallization of Perovskites Using Machine Learning‐Predicted Solvent Evaporation Rates for X‐Ray Detectors

open access: yesAdvanced Functional Materials, EarlyView.
By integrating machine learning into flux‐regulated crystallization (FRC), accurate prediction of solvent evaporation rates in real time, improving crystallization control and reducing crystal growth variability by over threefold, is achieved. This enhances the reproducibility and quality of perovskite single crystals, leading to reproducible ...

Microbubble‐Controlled Delivery of Biofilm‐Targeting Nanoparticles to Treat MRSA Infection

open access: yesAdvanced Functional Materials, EarlyView.
Here, an effective strategy using microbubble (MB)‐controlled delivery of biofilm‐targeting nanoparticles (BTNs) for removal and therapy of methicillin‐resistant Staphylococcus aureus (MRSA) biofilm infections is introduced. In vivo delivery of MB with BTN is demonstrated to silence key bacterial genes involved in biofilm formation (icaA), bacterial ...
