Copolymers of Poly(Butylene Trans‐1,4‐Cyclohexanedicarboxylate)/Pripol as New Biomaterial Platform for Small Diameter Vascular Graft

Advanced Healthcare Materials, EarlyView.
Electrospun tubular scaffolds from novel PBCE‐based copolyesters and blends were designed as candidates for small‐diameter vascular grafts. They combine defect‐free architecture, blood‐compatible surfaces, and mechanical properties comparable to native vessels.

Diels‐Alder Click Chemistry as a Dynamic‐Covalent Crosslinking Method in Spheroid‐Encapsulating Hydrogels for Cartilage Engineering

Advanced Healthcare Materials, EarlyView.
This research shows the development of hydrogels with Diels‐Alder click chemistry for engineering cartilage‐like tissue. The hydrogels support cartilage spheroids which could be cultured for at least 28 days. Furthermore, the spheroids showed a tendency to fuse together into a more consistent construct, and produced important components needed for ...

Sprayable Polymer Blends With Short‐Chain Surface Segregation for Preventing Postoperative Abdominal Adhesions

Advanced Healthcare Materials, EarlyView.
Adhesions’ high occurrence rates and high morbidity render them a critical challenge to be addressed. Current prevention methods, such as physical barriers, have many limitations, resulting in inconsistent safety and efficacy. This study demonstrates the potential for sprayable polymeric materials as an adhesion barrier.

Wide Binaries among High-Velocity and Metal-Poor Stars

Astrophysics and Space Science, 1999
The properties of old disk and halo binaries are of interest for the understanding of the processes of formation and early dynamical evolution of the Galaxy. The luminosity function of the components of wide binaries and multiples, their mass function, the fraction of halo or old disk stars that are members of wide binaries, and the distribution of ...

The Frequency of Wide Binaries among the Southern Barium Stars

Astrophysics and Space Science, 1988
All of the barium and marginal barium stars in the 1972 MacConnell, Frey, and Upgren (1972: MFU) list of such objects which are located south of the celestial equator were examined for visual duplicity. Over 200 objects were observed, and a total of six possible candidates for wide pair visual binaries were found. Of these, four are most likely optical

Searching for Planets Around Stars in Wide Binaries

2007
We present the status of the radial velocity planet search ongoing at TNG. We are observing about 50 wide binaries with similar components, searching for planets and abundance anomalies caused by the ingestion of metal-rich planetary material. A by-product of our project is the detection of several new spectroscopic binaries.

SLoWPoKES: A Catalog of Very Wide, Low-Mass Binary Stars

AIP Conference Proceedings, 2009
We present initial results from the Sloan Low‐mass Wide Pairs of Kinematically Equivalent Stars (SLoWPoKES) survey, an ongoing effort to identify wide (a>100 AU), low‐mass (mid‐K—mid M) binary systems from the Sloan Digital Sky Survey (SDSS) photometric database. Bochanski et al. (2009, in prep.) have compiled a catalog of more than 33 million low‐mass

On statistical distributions of wide binary stars

2017
The semi-major axis is a key parameter of binary stellar systems. In order to obtain current semi-major axis distribution we investigated a volume-limited sample of the binaries in solar neighbourhood. Obtained distribution shows unsatisfactory agreement with the canonical Opik's law.

Planetary System Disruption Within Wide Binary Star Systems

2011
Because they are so weakly bound, the orbits of wide binary stars evolve greatly under the influence of the Galactic tide and impulses from passing field stars. Most systems eventually pass through phases of high eccentricity, and this can have catastrophic consequences for the planets orbiting within these binary systems. During these eccentric phases,
