Surface electronic properties of undoped InAlN alloys [PDF]

, 2008
The variation in surface electronic properties of undoped c-plane InxAl1−xN alloys has been investigated across the composition range using a combination of high-resolution x-ray photoemission spectroscopy and single-field Hall effect measurements.

A Peculiar Family of Jupiter Trojans: the Eurybates [PDF]

, 2010
The Eurybates family is a compact core inside the Menelaus clan, located in the L4 swarm of Jupiter Trojans. Fornasier et al. (2007) found that this family exhibits a peculiar abundance of spectrally flat objects, similar to Chiron-like Centaurs and C ...

Research Status on Surface Modification of Materials by Low-Temperature Plasma [PDF]

Cailiao Baohu, 2022
As a new type of method to activate molecular, low-temperature plasma has a large number of active particles with various types, which are easy to react with the surface of the material, and is suitable for surface modification treatment of the materials.

Surface compositions of NEOs

Comptes Rendus. Physique, 2005
The physical characterization of the surfaces of Near Earth Objects (NEOs) is crucial to analyse the relationships among NEOs and the other populations of minor bodies of the Solar System (main-belt asteroids, comets and meteorites) and to investigate NEO origin and evolution.

Surface Chemical Composition of Diatoms [PDF]

ChemBioChem, 2009
AbstractAmong diatoms, Phaeodactylum tricornutum is a peculiar species that exists in three morphotypes with distinct cell wall structures and low silica content. X‐ray photoelectron spectroscopy (XPS) analysis was performed on P. tricornutum and compared with diatom Thalassiosira pseudonana; the results provide new information on the chemical ...

A CO2 Cycle on Ariel? Radiolytic Production and Migration to Low-latitude Cold Traps

The Planetary Science Journal, 2022
CO _2 ice is present on the trailing hemisphere of Ariel but is mostly absent from its leading hemisphere. The leading/trailing hemispherical asymmetry in the distribution of CO _2 ice is consistent with radiolytic production of CO _2 , formed by charged

Rotationally resolved spectroscopy of (20000) Varuna in the near-infrared [PDF]

, 2014
Models of the escape and retention of volatiles by minor icy objects exclude any presence of volatile ices on the surface of TNOs smaller than ~1000km in diameter at the typical temperature in this region of the solar system, whereas the same models show

Surface composition analysis of PP films treated by corona discharge

Materials Research, 2003
Polypropylene films (PP) surface treated by corona discharge in air was analyzed to verify the changes on surface composition. The presence of oxidized polar groups on the film surface, mainly, C=O, C-O and COH, was confirmed by infrared spectroscopy ...

Evidence for Nitrogen-bearing Species on Umbriel: Sourced from a Subsurface Ocean, Undifferentiated Crust, or Impactors?

The Planetary Science Journal, 2023
Near-infrared spectra of Umbriel and the other classical Uranian moons exhibit 2.2 μ m absorption bands that could result from ammonia (NH _3 ) bearing species, possibly exposed in the geologically recent past.
