Amine-reactive surface chemistry of zinc phosphate glasses
Autor: William Hertl, Emmanuel C. Onyiriuka, L. S. Hersh
Publikováno v: Journal of Materials Research. 10:2120-2127
Surface chemical studies on zinc phosphate glasses were carried out with an ammonia probe using FTIR and XPS. Low softening point zinc phosphate glasses can be co-extruded with high softening point polymers to form polymer filled blends. NH3 reacts w

Surface Modification of Polystyrene by Gamma-Radiation
Autor: L. S. Hersh, Emmanuel C. Onyiriuka, William Hertl
Publikováno v: Applied Spectroscopy. 44:808-811
The effect of gamma-radiation on the surface chemical properties of polystyrene was studied by ESCA and FT-IR. Gamma-radiation produces surface >C=O and C-O containing functional groups only, and also causes oxidation to depths >10 nm as detected by

Rapid Assay for Polystyrene Surface Oxidation
Autor: William Hertl, Emmanuel C. Onyiriuka, M. Bryhan, L. S. Hersh
Publikováno v: Applied Spectroscopy. 47:1609-1611
Polystyrene surfaces are often corona-discharge or plasma treated to oxidize the surface, which enhances the wettability. X-ray photoelectron spectroscopy (XPS), which requires time and an ultra-high vacuum, is generally used to measure this surface

Enzyme immunoassay for free thyroxin
Autor: L S Hersh, F B Ward, W Hertl, H H Weetall
Publikováno v: Clinical Chemistry. 28:666-671
We describe a mathematical model for a single-tube enzyme immunoassay for free thyroxin (FT4), involving use of a thyroxin/horseradish peroxidase (EC 1.11.1.7) conjugate that does not interact with thyroxin-binding globulin. In the presence of serum

Heats of Mixing in Liquid Alkali Nitrate Systems
Autor: L. S. Hersh, O. J. Kleppa
Publikováno v: The Journal of Chemical Physics. 34:351-358
The enthalpies of mixing in binary liquid alkali nitrate systems have been measured, and are all negative. It is found that the magnitude of the molar mixing enthalpy (ΔHM) increases in a regular fashion with increasing difference in size between th
