Dynamic Mechanical Loading Modulates Extracellular Vesicle Production and Cargo in Meniscus Fibrochondrocytes

open access: yesAdvanced Materials Interfaces, EarlyView.
Dynamic mechanical loading of outer meniscus fibrochondrocytes increases extracellular vesicle (EV) yield and alters EV composition. When applied to progenitor cells, these mechanically primed EVs modulate the expression of matrix‐related genes.

The Role of Compression Stockings in the Treatment of Patients with Vasovagal Syncope

open access: yesMajallah-i Dānishgāh-i ̒Ulūm-i Pizishkī-i Bābul, 2022
Syncope is a sudden, transient and complete decline in the level of consciousness during which the patient cannot maintain his/her muscle tone and falls to the ground. Recovery is usually spontaneous and quick. Stimulants such as standing for a long time,

Multilayered Digital Microfluidic Chip for Cell‐Based Assays

open access: yesAdvanced Materials Interfaces, EarlyView.
A multilayered digital microfluidic (mDMF) chip architecture is introduced to improve throughput and robustness in cell‐based assays. By multilayering electrode components and dielectric layers on glass, this design significantly reduces actuation voltage, maintains reliability, and enables expansion of the operational area with minimum current leakage.

Aggregation‐Controlled Vat Dyeing of Meta‐Aramid Fibers: Mechanistic Insights and Suppression of Surface Dye Deposition

open access: yesAdvanced Materials Interfaces, EarlyView.
Supramolecular aggregation governs the interfacial adsorption, diffusion, and fixation of anthraquinone‐based vat dyes in meta‐aramid fibers. By correlating reduction chemistry, aggregate formation, and fiber microstructure, a multiscale mechanism for aggregation‐controlled dyeing is established, providing an effective strategy to suppress surface dye ...

Photodoping in Wide‐Bandgap Perovskite Solar Cells With MXenes

open access: yesAdvanced Optical Materials, EarlyView.
Ultrafast tandem spectroscopy and DFT modeling reveal the separate dynamics and the imbalance of electrons and holes in wide bandgap perovskite solar cells with MXene incorporation. The enhanced photoconversion performances of the devices are traced to photodoping, with selective hole trapping and suppressed recombination of electrons.

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures

open access: yesAdvanced Robotics Research, EarlyView.
Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.

Molecular Appendix Adjusted Architectural Propagations of Red‐Light Controlled Macroscopic Photoactuating Performances

open access: yesAdvanced Robotics Research, EarlyView.
Amphiphilic chloroazobenzenes, bearing different amino acids as end groups alanine, phenylalanine, and valine, exhibit excellent photoisomerizations. Varying structures of three amino acid groups participate in supramolecular formations and therefore photoinduced morphological transformations via adjusting intermolecular interactions. These interaction

Perivascular Matrix Densification Dysregulates Angiogenesis and Activates Pro‐Inflammatory Endothelial Cells

open access: yesAdvanced Science, EarlyView.
Perivascular matrix densification promotes the emergence of aberrant endothelial tip cells (ATECs) that invade and persist within fibrotic microenvironments. Using in vivo lineage tracing and a human microvessel model, this study shows that fibrous matrix cues destabilize VE‐cadherin–mediated junctions to gate TGF‐β signaling, inducing a pro ...
