SiC has been investigated for use as a direct energy converter (DEC) for nuclear batteries. A solid state model is being developed to calculate the electrical output of a diode into a resistively loaded circuit. This paper describes the use of a nuclear scattering code (MCNPX) to calculate the increased electron density that would be expected in a SiC material based on exposure to a Sr90 beta
Diesel fired lubricant testing encompassing standardized gasoline and diesel engine dynamometer tests, used in the evaluation of crankcase lubricants. Standardized ASTM lubricant testing procedures are used for evaluating lubricants against standards published by the American Petroleum Institute (API), military, and various engine manufacturers.
Nov 17, 2012Fourteen Fourier transform spectra of ethylene (C2H4) have been recorded in the 1800 2350 spectral domain with different path lengths and pressures and used to derive individual line intensities for lines belonging to the 7 + 8, 4 + 8 , 6 + 10, 6 + 7, 4 + 6 and 3 + 10 bands.
Alert Cryogenic vials are intended for placement only in the vapor phase of liquid nitrogen, and should not be used for storage in the liquid phase of liquid nitrogen. Immersion of the vials in the liquid phase could result in penetration of the liquefied gas into the vial, resulting in rapid vaporization of the liquid upon removal and possible violent explosion or leakage from the vial

1.1 This test method covers the determination of methyl groups (that is, comonomer content) in polyethylenes by infrared spectrophotometry. The test method is applicable to copolymers of ethylene with 1 butene, 1 hexene, or 1 octene having densities above 900 kg/m 3.High pressure low density polyethylenes (LDPE) and terpolymers are excluded.
