The nature of soil to be deterged and its bonding to the surface

Foster Dee Snell、Cornelia T. Snell、Irving Reich1950-02-01Journal of the American Oil Chemists Society

Summary Asoil is ordinarily composed in varying amounts of oil, wax, or grease; solid particles of diverse types; and special water‐soluble or water‐dispersible materials such as sugar, salts, starch, etc. Quantitatively the fatty portion on fabrics may run to a substantial fraction of 1% and contains roughly one‐thir…

Depolymerization by Ultrasonic Irradiation: The Role of Cavitation

Alfred Weissler1950-02-01Journal of Applied Physics

Contrary to current belief, cavitation has been found responsible for the depolymerizing effect of intense ultrasonic waves. This was demonstrated by irradiating two portions of a 1 percent polystyrene solution in toluene under conditions identical except for the following. The first portion was given no special prior…

Structural Investigations by Means of Nuclear Magnetism. II. Hindered Rotation in Solids

H. S. Gutowsky、G. E. Pake1950-02-01The Journal of Chemical Physics

The experimental absorption line widths, for nuclei with spin 1/2, at nuclear magnetic resonance are given as a function of temperature for a number of molecular crystals. Temperatures ranged from 90°K to the melting points of the compounds. In some cases it has been possible to relate observed line structure and tran…
