Ion-induced electrostatic charging of ice at 15–160 K
We studied electrostatic charging of ice films induced by the impact of 1−200-keV Ar+ ions and their subsequent discharging postirradiation. We derived the positive surface electrostatic potential from the kinetic energy of sputtered molecular ions and with a Kelvin probe. Measurements were performed as a function of film thickness, temperature, and ion energy. Charging requires that the projec...
متن کاملCharacterization of various low-k dielectrics for possible use in applications at temperatures below 160 °C
This study aims at the testing of various low-k insulators deposited at temperatures below approximately 160 C for possible application in temperature-limited copper interconnects (e.g., in plastic electronics). Various polymers were tested such as the well-known poly(methyl methacrylate) (PMMA), a Polyhedral Oligomeric Silsesquioxane (POSS) based copolymer partially fluorinated (POSS-F) and th...
متن کاملSimilarities and differences in radiation damage at 100 K versus 160 K in a crystal of thermolysin.
The temperature-dependence of radiation damage in macromolecular X-ray crystallography is currently much debated. Most protein crystallographic studies are based on data collected at 100 K. Data collection at temperatures below 100 K has been proposed to reduce radiation damage and above 100 K to be useful for kinetic crystallography that is aimed at the generation and trapping of protein inter...
متن کاملShock temperature in calcite (CaCO3) at 95^160 GPa
The temperatures induced in crystalline calcite (CaCO3) upon planar shock compression (95^160 GPa) are reported from two-stage light gas gun experiments. Temperatures of 3300^5400 K are obtained by fitting six-channel optical pyrometer radiances in the 450^900 nm range to the Planck gray-body radiation law. Thermodynamic calculations demonstrate that these temperatures are some 400^1350 K lower...
متن کاملSURVEY OF NEARBY FGK STARS AT 160 μm WITH SPITZER
The Spitzer Space Telescope has advanced debris disk science tremendously with a wealth of information on debris disks around nearby A, F, G, K and M stars at 24 and 70 μm with the MIPS photometer and at 8-34 μm with IRS. Here we present 160 μm observations of a small sub-set of these stars. At this wavelength, the stellar photospheric emission is negligible and any detected emission correspond...
