Hypervelocity binary stars: smoking gun of massive binary black holes

open access: yes, 2007
The hypervelocity stars recently found in the Galactic halo are expelled from the Galactic center through interactions between binary stars and the central massive black hole or between single stars and a hypothetical massive binary black hole.

Xeno‐Free Biocompatible Peptide‐Based Bioinks Reinforced with Cellulose Nanofibers for 3D Printing

open access: yesAdvanced Healthcare Materials, EarlyView.
A xeno‐free bioink combining self‐assembled peptides and cellulose nanofibers is developed for 3D printing. The bioink forms a non‐cross‐linked 3D scaffold, mimicking the extracellular matrix and supporting over 95% cell viability. This approach offers enhanced biocompatibility and mechanical stability, advancing 3D printing for personalized medicine ...

Hypervelocity runaways from the Large Magellanic Cloud

open access: yes, 2017
We explore the possibility that the observed population of Galactic hypervelocity stars (HVSs) originate as runaway stars from the Large Magellanic Cloud (LMC).

Recombinant Proteins: A Molecular Tool to Understand Marine Adhesion and to Advance Biomaterials

open access: yesAdvanced Healthcare Materials, EarlyView.
The production of recombinant proteins represents a fundamental step in the characterisation of marine invertebrate adhesives and in the development of bio‐inspired glues. The association of these proteins with other components such as ions, proteins, polysaccharides, or polymers enables the fabrication of biomaterials for various healthcare ...

Granular Hydrogels as Modular Biomaterials: From Structural Design to Biological Responses

open access: yesAdvanced Healthcare Materials, EarlyView.
Granular hydrogels are now emerging as promising biomaterials due to their inherent microporousity, injectability, and modularity. They have shown improvements in cell viability and migration, cellular/tissue infiltration, host tissue integration, mitigated foreign body response, and tissue regeneration.

Shedding Light on the Cellular Uptake Mechanisms of Bioactive Glass Nanoparticles as Controlled Intracellular Delivery Platforms: A Review of the Recent Literature

open access: yesAdvanced Healthcare Materials, EarlyView.
This review summarizes the main uptake pathways of bioactive glass nanoparticles (BGNs) and their intracellular localization, highlighting that BGNs are mainly internalized and entrapped within endosomes/lysosomes. Strategies for controlled intracellular ion release, with implications for targeted modulation of cell behavior, are discussed. The need to

Three-body encounters in the Galactic centre: the origin of the hypervelocity star SDSS J090745.0+024507

open access: yes, 2005
Hills (1988) predicted that runaway stars could be accelerated to velocities larger than 1000 km/s by dynamical encounters with the supermassive black hole (SMBH) in the Galactic center.
