Concentrated Solution

Heats of dilution have been exhaustively studied by Prof. Julius Thomsen for a very large number of aqueous solutions.* His method chiefly consisted in taking some concentrated solution and diluting it considerably. The total amount of heat generated or absorbed in this process was thus found and quoted against the final concentration expressed in molecules of water to one molecule of solute. It is to be noted that during the process of dilution most of the thermal change occurs in the early stages, and that after the first ten molecules of water are added the total heat generated or absorbed increases but slightly. The probable reason for this procedure is, that the experimenter finishes the operation with a dilute solution, so that starting with various initial concentrations, he may need only a few specific heats of certain dilute solutions. It must be remembered that only the final .specific heat of the solution need be known in order to measure the heat generated.

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.
