All recent methods for the isolation of the ribonucleic acids from yeast yield only 20 to 70 per cent of the ribonucleic acids that can be assumed to be present on the basis of quantitative analyses. There have been no studies regarding the nature of the ribonucleic acids that are lost during isolation, but it has tac…

Abstract Further experiments by transmission electron microscopy on thin sections of stainless steel deformed by small amounts have enabled extended dislocations to be observed directly. The arrangement and motion of whole and partial dislocations have been followed in detail. Many of the dislocations are found to hav…

The electrical resistivity, Hall coefficient, and thermoelectric power of microscopic boron single crystals have been measured as a function of temperature. Rectification and photoconductivity effects were observed at room temperature. The large majority of these single crystals had a high resistivity (about 1.7\ifmmo…

Bernhard Groß1957-07-15Physical Review
Irradiation of thick samples of borosilicate glass with high-energy electrons introduces space charges into the dielectric, the decay of which is extremely slow at room temperature. The charged dielectric shows a behavior similar to that of an electret; charges are induced on adjacent conductors and short-circuit disc…

Abstract Es wird die Darstellung des Azulens durch Kondensation von Cyclopentadien mit Glutacondialdehyd‐Derivaten beschrieben. Die Synthese erfordert keine Dehydrierungsreaktion und verläuft mit einer Azulen‐Ausbeute von 65% der Theorie. Auf dem gleichen Wege können auch substituierte Azulene hergestellt werden.
