Advanced Engineering Materials, EarlyView.Heat treatment parameters critically affect the wear resistance of powder bed fusion–laser beam (PBF‐LB)‐produced Ti–6Al–2Sn–4Zr–6Mo alloy. This study found that optimizing annealing temperature allows to obtain a tailored microstructure, which enhances the dry‐sliding behavior by forming a stable and functional mechanically mixed layer (MML), ensuring

JWST/MIRI Imaging of the Warm Dust Component of the ϵ Eridani Debris Disk
The Astronomical JournalWe present JWST/MIRI observations of the debris disk surrounding the nearby solar analog ϵ Eridani obtained as part of the Archetypal Debris Disk Guaranteed Time Observation program. Multiwavelength images from 15, 18, 21, and 25.5 μ m show a smooth dust

Shocks Power Tidal Disruption Events
The Astrophysical Journal, 2023 Accretion of debris seems to be the natural mechanism to power the radiation emitted during a tidal disruption event (TDE), in which a supermassive black hole tears apart a star.

Advanced Functional Materials, EarlyView.The addition of calcium ions to silk fibroin enhances the hydrogel properties and, when combined with visible light crosslinking, enables compatibility with advanced light‐based fabrication techniques. Calcium ions extend the shelf‐life of silk and facilitate the fabrication of multizonal, multilayered constructs for advanced stimuli‐responsive ...

Gemini Planet Imager Observations of a Resolved Low-inclination Debris Disk around HD 156623
The Astronomical JournalThe 16 Myr old A0V star HD 156623 in the Scorpius–Centaurus association hosts a high-fractional-luminosity debris disk, recently resolved in scattered light for the first time by the Gemini Planet Imager (GPI) in polarized intensity only.

Biomaterial Strategies for Targeted Intracellular Delivery to Phagocytes
Advanced Functional Materials, EarlyView.Phagocytes are essential to a functional immune system, and their behavior defines disease outcomes. Engineered particles offer a strategic opportunity to target phagocytes, harnessing inflammatory modulation in disease. By tuning features like size, shape, and surface, these systems can modulate immune responses and improve targeted treatment for a ...

Advanced Functional Materials, EarlyView.A 3D bone scaffold with osteogenic properties and capable of hardening in vivo is developed. The scaffold is implanted in a ductile state, and a phase transformation of the ceramic induces the stiffening and strengthening of the scaffold in vivo. Abstract Calcium phosphate 3D printing has revolutionized customized bone grafting.
