Ti6Al4V‐Bioglass‐Copper Composites for Load‐Bearing Implants

open access: yesAdvanced Healthcare Materials, EarlyView.
We have designed and manufactured a novel Ti64‐based composite by adding 45S5 bioglass (BG) and copper (Cu). Adding BG on titanium improves wear resistance and biocompatibility, whereas Cu addition improves mechanical strength while providing inherent lifelong bacterial resistance.

Radial Surface Density Profiles of Gas and Dust in the Debris Disk around 49 Ceti [PDF]

open access: yes, 2017
We present ∼0.″4 resolution images of CO(3–2) and associated continuum emission from the gas-bearing debris disk around the nearby A star 49 Ceti, observed with the Atacama Large Millimeter/Submillimeter Array (ALMA).

ETV2 Mediated Differentiation of Human Pluripotent Stem Cells Results in Functional Endothelial Cells for Engineering Advanced Vascularized Microphysiological Models

open access: yesAdvanced Healthcare Materials, EarlyView.
A robust method to generate functional human iPSC‐derived endothelial cells using inducible ETV2 expression. These cells self‐organize into stable, lumenized microvascular networks within microfluidic chips, surpassing conventional differentiation methods.

Discovery of a Debris Disk around TWA 20

open access: yesThe Astrophysical Journal
We report the discovery of a debris disk surrounding the M3 star TWA 20, revealed by JWST coronagraphic observations using the Near Infrared Camera. With reference differential imaging (RDI), we resolve the disk in scattered light in the F200W filter at ...

Sticking of Fine Particles in High-velocity Impact: Application to Size Distribution of Dust Grains in a Debris Disk

open access: yesThe Astrophysical Journal, 2023
Impact experiments were conducted at a velocity of ∼0.2–1.0 km s ^−1 using fine particles with several microns or submicrons in size. For metal (Cu) plate targets, as observed in previous impact experiments using projectiles with sizes larger than tens ...

Resolved Millimeter Observations of the HR 8799 Debris Disk [PDF]

open access: yes, 2018
We present 1.3 mm observations of the debris disk surrounding the HR 8799 multi-planet system from the Submillimeter Array to complement archival ALMA observations that spatially filtered away the bulk of the emission.

The Exceptionally Large Debris Disk around γ Ophiuchi [PDF]

open access: yesThe Astrophysical Journal, 2008
Spitzer images resolve the debris disk around Ophiuchi at both 24 and 70 um. The resolved images suggest a disk radius of ~520 AU at 70 um and >=260 AU at 24 um. The images, along with a consistent fit to the spectral energy distribution of the disk from 20 to 350 um, show that the primary disk structure is inclined by ~50 degree from the plane of

Oxygen and ROS Delivery for Infected Wound Healing and Future Prospects

open access: yesAdvanced Healthcare Materials, EarlyView.
Bacterial infection is a major driver of delayed wound healing and postsurgical readmissions; with rising antibiotic resistance, solid peroxide–releasing biomaterials offer sustained delivery of ROS/O2 for antimicrobial control and microenvironmental modulation.

THE STRUCTURE OF THE β LEONIS DEBRIS DISK [PDF]

open access: yesThe Astrophysical Journal, 2010
We combine nulling interferometry at 10 m using the MMT and Keck Telescopes with spectroscopy, imaging, and photometry from 3 to 100 m using Spitzer to study the debris disk around Leo over a broad range of spatial scales, corresponding to radii of 0.1 to ~100 AU.
