Quantitative electron spectroscopy of surfaces: A standard data base for electron inelastic mean free paths in solids

Abstract: A compilation is presented of all published measurements of electron inelastic mean free path lengths in solids for energies in the range 0–10 000 eV above the Fermi level. For analysis, the materials are grouped under one of the headings: element, inorganic compound, organic compound and adsorbed gas, with the path lengths each time expressed in nanometers, monolayers and milligrams per square metre. The path lengths are vary high at low energies, fall to 0.1–0.8 nm for energies in the range 30–100 eV and then rise again as the energy increases further. For elements and inorganic compounds the scatter about a ‘universal curve’ is least when the path lengths are expressed in monolayers, λm. Analysis of the inter-element and inter-compound effects shows that λm is related to atom size and the most accuratae relations are λm = 538E−2+0.41(aE)1/2 for elements and λm=2170E−2+0.72(aE)1/2 for inorganic compounds, where a is the monolayer thickness (nm) and E is the electron energy above the Fermi level in eV. For organic compounds λd=49E−2+0.11E1/2 mgm−2. Published general theoretical predictions for λ, valid above 150 eV, do not show as good correlations with the experimental data as the above relations.

Preparation of additive for powdery and granular detergents

Abstract: PURPOSE:To obtain an additive capable of maintaining good powder properties even after a long-term preservation when incorporated with powder and granular detergents, by incorporating a solid organic substance with a crystalline inorganic compound and water under specific conditions. CONSTITUTION:(A) A solid organic substance, e.g. higher alcohol, etc. solid at room temperature is incorporated with (B) 0.5-2 times the amount of water of crystallization of an inorganic compound, e.g. sodium sulfate, etc., which crystallizes at room temperature in the presence of the water of crystallization. The mixture is then melt kneaded by irradiation of ultrasonic waves, mixed with the inorganic compound described above, then cooled to give the desired additive.

Surface treated granule material for treating waste water

Abstract: PURPOSE:A waste water treating granule material having an excellent mechanical stability and oil removal efficiency is provided in such a way that granules consisting of mixture of oil absorbing inorganic compound and binder as well as hydrophilic organic material are treated by surfactant on their surface. CONSTITUTION:A mixture is made from 95 to 40% by weight of inorganic compound such as alumina and 5 to 60% by weight of binder such as alumina sol. If hydrophilic organic compound is to be contained in the mixture, the mixture is made from 95 to 5% by weight of inorganic compound, 5 to 80% by weight of binder, and 5 to 90% by weight of hydrophilic organic compound. These mixtures are blended, extruded, granuled and dried or heat treated to enhance mechanical strength. The resulting granules are immersed in a 0.1 to 10% solution of surfactant such as alkyl trimethyl ammonium chloride to be deposited with surfactant on the surface of the granules to enhance the oil containing waste watet treating property.
