The Hunt for Exomoons with Kepler (HEK): I. Description of a New Observational Project

, 2012
Two decades ago, empirical evidence concerning the existence and frequency of planets around stars, other than our own, was absent. Since this time, the detection of extrasolar planets from Jupiter-sized to most recently Earth-sized worlds has blossomed ...

Unlocking the Power of Quercetin‐Encapsulated Mesoporous Bioactive Glass Nanoparticles: A Multifunctional Approach to Bone Regeneration

Advanced Engineering Materials, EarlyView.
Mesoporous bioactive glass nanoparticles (MBGNs) are investigated for bone regeneration given their remarkable structural and functional properties. MBGNs are functionalized with Mn and Cu and incorporated with quercetin, a natural flavonoid exhibiting antioxidant, anti‐inflammatory, and antimicrobial properties.

A Comprehensive Review of Additive Manufacturing for Space Applications: Materials, Advances, Challenges, and Future Directions

Advanced Engineering Materials, EarlyView.
Additive manufacturing (AM) transforms space hardware by enabling lightweight, high‐performance, and on‐demand production. This review outlines AM processes—powder bed fusion (PBF), directed energy deposition (DED), binder jetting (BJ), sheet lamination (SL), and material extrusion (ME)—applied to propulsion, satellite structures, and thermal devices ...

Estimates of African Dust Deposition Along the Trans‐Atlantic Transit Using the Decadelong Record of Aerosol Measurements from CALIOP, MODIS, MISR, and IASI

Journal of Geophysical Research - Atmospheres, 2019
Deposition of mineral dust into ocean fertilizes ecosystems and influences biogeochemical cycles and climate. In situ observations of dust deposition are scarce, and model simulations depend on the highly parameterized representations of dust processes ...

Transit, the Navy Navigation Satellite System

Navigation, 1971
So much has happened in this world since October 4, 1957, it is difficult to realize that fewer than 14 years have passed since the launch of Sputnik I, the first artificial earth satellite. Technology has leapt forward from those first "beeps" in space to produce worldwide communication and weather monitoring systems, spies-in-the sky, astronomical ...

The Hunt for Exomoons with Kepler (HEK): III. The First Search for an Exomoon around a Habitable-Zone Planet

, 2013
Kepler-22b is the first transiting planet to have been detected in the habitable-zone of its host star. At 2.4 Earth radii, Kepler-22b is too large to be considered an Earth-analog, but should the planet host a moon large enough to maintain an atmosphere,

Highly Stable Low‐Temperature Phosphate Glass as a Platform for Multimaterial 3D Printing of Integrated Functional Microfluidic Devices

Advanced Engineering Materials, EarlyView.
A highly stable, low‐temperature phosphate glass is developed for multimaterial additive manufacturing of multifunctional microfluidics. Glass, metal conductors, and sacrificial polymer are coprinted, enabling monolithic fabrication. The sacrificial paste forms precise channels and decomposes during sintering.
