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…

From information on pollution-tolerant algae compiled from reports from 165 authors, the genera and species most often referred to as significant fall into a relatively stable series. Diatoms, pigmented flagellates, green, and blue-green algae are all well represented among the pollution-tolerant genera and species. T…
Abstract It has been known for many years that deformation results in softening of rubber and that the initial stress-strain curve determined during the first deformation is unique and cannot be retraced. Further the effect of repeated deformation is to cause rubber asymptotically to approach a steady state with a con…
Gold, silver, and silver iodide sols were prepared in mixed nitrate melts. Electron micographs of the gold and silver sols show particles smaller than 1 micron. The gold sols exhibit conventional absorption and scattering spectra. Both gold amid silver sols show unusual stability.
Most of the small particles (50 to 100 micrometers in diameter) of microcrystalline beta-rhombohedral boron that quickly transit an argon plasma maintained within a radio-frequency induction-coupled torch emerge as better crystallized spheroids of the same crystalline form and nearly the same size as the starting mate…
