We have measured magnetization isotherms for single crystals of monoclinic Cu(NO3)2·2.5H2O between 1.2° and 4.2°K by a ballistic method. Fields up to 43 kOe were applied along the b axis, i.e., the long axis of the needlelike specimens. The character of the M vs H curves changes rapidly in this temperature interval. T…

Saturation magnetizations in the binary Fe–Co system were redetermined since an earlier investigation (P. Weiss and R. Forrer, Ann. Phys. 12, 1929) was made prior to the discovery of a CsCl-type ordered structure that has a wide solubility range. The alloys were quenched from 850°C at various rates in an attempt to su…
Abstract Infraref internal reflection spectroscopy has been used to study the adsorption of certain plasma proteins on a variety of hydrophobic polymer surfaces. The behavior of the systems studied was almost identical. Under Static conditions the proteins appear to be rapidly adsorbed as monomolecular layers from sol…
Abstract Recording ellipsometers and surface film balance, breath patterns, and ferric oxide powder “staining” were used to observe adsorption of normal plasma constituents onto metal oxide, silicon oxide, and polymer surfaces. Adsorbed proteins could be identified by their ability to adsorb matter from corresponding…
Abstract The nature of the events occurring immediately after exposing foreign surfaces to fresh flowing blood was assessed using a combination of MAIR infrared spectroscopy, ellipsometry, and contact angle measurements. Within the first 5 sec after contact with blood issuing from the jugular veins of lightly anesthes…

The symmetry of a magnetic crystal can be described by one of the black and white Shubnikov point groups containing both unitary and anti-unitary elements. The theory is reviewed that enables a tensor to be symmetry adapted to any one of the irreducible corepresentations of a non-unitary group and it is applied to the…

Abstract Thermogravimetric analyses (TGA) of catalyst‐free polydimethylsiloxanes (PDMS) have been carried out in controlled atmospheres and a kinetic analysis of the results has enabled the various decomposition processes to be separated and identified. The calculated activation energy for thermal depolymerization is…
Single crystals of BaFe12O19 and SrFe12O19 were grown in a Na2O flux. Static magnetic measurements on the two crystal types were made to reveal Ms and K1 as functions of temperature. It was found that Ms of BaFe12O19 and SrFe12O19 are practically identical over the temperature range 77°K to the Curie point with a room…
