Tetramethylammonium Bromide

The activity coefficients up to saturation, some conductances and densities, and the solubility in water have been measured for tetramethylammonium bromide and tetramethylammonium iodide. Ion association exists and the ion-pair constants have been calculated by three methods. The standard entropy of the aqueous (CH3)4N+ ion has been calculated.

The trace diffusion of iodide ion in aqueous calcium and cadmium perchlorate solutions has been followed in diaphragm cells using the radio tracer method. The trace diffusion coefficients in the cadmium perchlorate solutions have been used to calculate the limiting mobility of the CdI+ ion.

Ultrathin Frozen Sections

During the last years it was shown that also by means of cryo-ultra-microtomy a good preservation of substructural details of biological material was possible. However the specimen generally was prefixed in these cases with aldehydes.Preparing ultrathin frozen sections of chemically non-prefixed material commonly was linked up to considerable technical and manual expense and the results were not always satisfying. Furthermore, it seems to be impossible to carry out cytochemical investigations by means of treating sections of unfixed biological material with aqueous solutions.We therefore tried to overcome these difficulties by preparing yeast cells (S. cerevisiae) in the following manner:

The atomic force microscope (AFM) is an instrument that can be used to image many samples of interest in biology and medicine. Images of polymerized amino acids, polyalanine and polyphenylalanine demonstrate the potential of the AFM for revealing the structure of molecules. Images of the protein fibrinogen which agree with TEM images demonstrate that the AFM can provide topographical data on larger molecules. Finally, images of DNA suggest the AFM may soon provide an easier and faster technique for DNA sequencing.The AFM consists of a microfabricated SiO2 triangular shaped cantilever with a diamond tip affixed at the elbow to act as a probe. The sample is mounted on a electronically driven piezoelectric crystal. It is then placed in contact with the tip and scanned. The topography of the surface causes minute deflections in the 100 μm long cantilever which are detected using an optical lever.
