Detecting New Planets in Transiting Systems

, 2006
I present an initial investigation into a new planet detection technique that uses the transit timing of a known, transiting planet. The transits of a solitary planet orbiting a star occur at equally spaced intervals in time.

Bulk and Surface Dual‐Modification for Stabilizing RuO2 Anode in 2 A cm−2 PEMWE Operation

Advanced Materials, EarlyView.
The high‐current‐density stability of the RuO2‐based anode in PEMWE could be taken care of by a bulk and surface dual modification strategy developed in this work, where Cr doping modulates the Ru valence state in the bulk phase, suppressing Ru overoxidation, whereas Si modification stabilizes the reaction interface by inhibiting catalyst ...

Tilted Circumbinary Planetary Systems as Efficient Progenitors of Free-floating Planets

The Astrophysical Journal Letters
The dominant mechanism for generating free-floating planets has so far remained elusive. One suggested mechanism is that planets are ejected from planetary systems due to planet–planet interactions.

A Mechanistic Study of Bio‐Based Nanotemplated Carbon Nanofibers Derived From Water Processable Lignin Blends for Sustainable Energy Storage Applications

Advanced Materials, EarlyView.
As‐spun carbon materials produced from Lignosulfonate, gelatin, and alginate, selected for water solubility, and ability to produce templated sustainable carbon nanostructures. Gelatin and alginate are sacrificial during thermal processing, allowing the production of engineered high surface area nanostructures, which are further characterized for ...

Earth and Terrestrial Planet Formation

, 2015
The growth and composition of Earth is a direct consequence of planet formation throughout the Solar System. We discuss the known history of the Solar System, the proposed stages of growth and how the early stages of planet formation may be dominated by ...

An Atomic‐Level Bimetallic MOF Platform Overcoming the Stability‐Performance Tradeoff for Laser Propulsion

Advanced Materials, EarlyView.
This work introduces an atomic‐level engineered bimetallic MOF Platform that resolves the inherent trade‐off between environmental stability and propulsion efficiency. By integrating robust Fe‐O bonds for hydrolysis resistance and enabling d‐orbital charge transfer (Fe3+→Cu2+) for enhanced photothermal conversion, the design achieves a highly durable ...
