Geometrical Designs in Volumetric Bioprinting to Study Cellular Behaviors in Engineered Constructs

Advanced Healthcare Materials, EarlyView.
Curvature and spatial confinement guide cell behavior in volumetrically printed 3D constructs. Endothelial cells align and spread along specific geometries, while metastatic osteosarcoma cells proliferate independently of structural cues. Label‐free holographic microscopy captures real‐time, long‐term cell–material interactions, highlighting Gel‐PEG's ...

Star−Disk Collisions: Implications for Quasi-periodic Eruptions and Other Transients near Supermassive Black Holes

The Astrophysical Journal
We use Athena++ to study the hydrodynamics of repeated star−accretion disk collisions close to supermassive black holes, and we discuss their implications for the origin of quasi-periodic eruptions (QPEs) and other repeating nuclear transients.

The Promise of Solid Lubricants for a Sustainable Future

Advanced Materials, EarlyView.
Lubricants are vital for technology, saving energy and resources. The industry seeks sustainable solutions beyond fossil fuels. Solid lubricants offer extremely low friction and reduce environmental impact, especially in harsh conditions. Can these solids truly replace liquid lubricants, or are they limited to extreme applications?

Bacteria‐Responsive Nanostructured Drug Delivery Systems for Targeted Antimicrobial Therapy

Advanced Materials, EarlyView.
Bacteria‐responsive nanocarriers are designed to release antimicrobials only in the presence of infection‐specific cues. This selective activation ensures drug release precisely at the site of infection, avoiding premature or indiscriminate release, and enhancing efficacy.

Imaging of the Vega Debris System Using JWST/MIRI

The Astrophysical Journal
We present images of the Vega planetary debris disk obtained at 15.5, 23, and 25.5 μ m with the Mid-Infrared Instrument on JWST. The debris system is remarkably symmetric, smooth, and centered accurately on the star.

Straightforward Preparation of Polyurethane‐Based Biomaterials with Dual Antibacterial and Anti‐Adhesive Properties for Long‐Lasting Catheter Applications

Advanced Materials Interfaces, EarlyView.
This study presents the elaboration of antibacterial, antiadhesive, and antibiofilm polyurethane by a straightforward process based on the co‐extrusion of 2 wt.% of both antibacterial and antiadhesive copolymer. The material proves to be active even after pre‐exposition to biological media and prevents E. coli biofilm formation without toxicity.

Advanced Ceramics in Aerospace and Defense: The Interrelationship between Traditional and Additive Manufacturing Approaches

Advanced Materials Technologies, EarlyView.
Additive manufacturing revolutionizes production by enabling on‐demand, customized, and sustainable manufacturing with streamlined supply chains. While metal and polymer AM are well‐established, advanced ceramic AM is rapidly emerging, overcoming traditional material challenges.
