Magnetically-supported

The problem of surface magnetism and of the magnetic properties of thin metal films supported, or epitaxially grown onto single crystal substrates is also developing with an open interest for the possible exploitation of magnetic supports for information... 

The samples are contained in a demountable cell consisting of 2 CaF2 plates separated by a spacer of 10 or 20 micron. The sample cell is filled through two metal tubes drilled through and glued to the first CaF2 plate. The sample cell is held on to the Lissajous scanner by three magnetic supports. 

Although Rhone-Poulenc has given up direct upstream development after fruitless association with Dysan in magnetic supports and Siltec in silicon, it still believes it can use its know-how in rare earths to develop their electronics applications. Today, Rhone-Poulenc is the indisputable leader in rare earths, accounting for 40 percent of the world market. At its units in La Rochelle, France, and Freeport, Texas, it is capable of extracting from lanthanide sands the fourteen elements they contain. Over the last few years, samarium, for instance, has become essential for microelectronics to the same degree that europium and yttrium oxides already are for color television. 

Coupling proteins (by covalent methods) to magnetic supports is the most common approach (105). Various classes of proteins, such as lectins (110) and antibodies (111), and a large number of enzymes including invertase (112,113), papain (106, 114) a-chymotrypsin (114, 115), P-galactosidase (114), adenylate kinase (112), acetate kinase (112), and horseradish peroxidase (112), have been immobilized. In fact, such supports are now commercially available, for example, Enzacryl FEO-M (available from Aldrich Chemictd Company, USA) and Dyna (sold by Dynal, Norway).
