Direct Detection of Extra-Solar Comets is Possible

, 2005
The dust tails of comets similar to Hale-Bopp can scatter as much optical light as does the Earth. Space-based observatories such as the Terrestrial Planet Finder or Darwin that will detect extra-solar terrestrial planets also will be able to detect ...

3D Printing of Highly Electrically Conductive Zinc for Sustainable Electronics Applications

Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
A 3D printable zinc ink system with active zinc particles in a shellac matrix is demonstrated. The results show high conductivity, stable performance of printed structures under varying humidity conditions, and promising application in disposable water‐activated batteries. This technology combining digital material assembly, reliable operation, and non‐

Critical Masses for Various Terrestrial Planet Atmospheric Gases and Water in/on Mars

Terrestrial, Atmospheric and Oceanic Sciences, 2014
The lower critical mass boundaries (CM) for various atmospheric gas species on terrestrial planets are estimated. The CM is different for different gas molecules.

Oligarchic and giant impact growth of terrestrial planets in the presence of gas giant planet migration

, 2005
We present the results of N--body simulations which examine the effect that gas giant planet migration has on the formation of terrestrial planets. The models incorporate a 0.5 Jupiter mass planet undergoing type II migration through an inner protoplanet-

Tailoring the Electrochemical Performance of SnO2‐Based Anodes for Li‐Ion Batteries: Effect of Morphology and Composite Matrix

Advanced Materials Technologies, EarlyView.
Three different composite anodes, based on SnO2, are investigated as potential anode materials for lithium‐ion batteries. Three different strategies are employed to stabilize SnO2 upon cycling i.e., i) use of an inorganic matrix (TiO2), ii) use of an amorphous carbon matrix, and iii) use of SnO2 with a tailored morphology (nanorod) and a carbon coating.

The Impact of Extended CO2 Cross Sections on Temperate Anoxic Planet Atmospheres

The Astrophysical Journal
Our interpretation of terrestrial exoplanet atmospheric spectra will always be limited by the accuracy of the data we use as input in our forward and retrieval models.

High-resolution simulations of the final assembly of Earth-like planets 2: water delivery and planetary habitability

, 2007
The water content and habitability of terrestrial planets are determined during their final assembly, from perhaps a hundred 1000-km "planetary embryos" and a swarm of billions of 1-10 km "planetesimals." During this process, we assume that water-rich ...

Development of a Miniaturized Capillary Rheometer for High Shear Rate Rheology of Dense Suspensions

Advanced Materials Technologies, EarlyView.
This research presents a downscaled benchtop, low‐cost capillary rheometer that can characterize high shear rate rheometry of dense suspensions. The device is capable of measuring across a wide range of applicable shear rates using only a limited quantity of material and addresses a need for an accurate and affordable capillary rheometer.

Terrestrial Zone Debris Disk Candidates in h and chi Persei

, 2007
We analyze 8 sources with strong mid-infrared excesses in the 13 Myr-old double cluster h and chi Persei. New optical spectra and broadband SEDs (0.36-8 mu_m) are consistent with cluster membership. We show that material with T ~ 300-400 K and Ld/Lstar ~
