SLAC-PUB-1667 (Rev.) November 1975 Revised May 1976 (1) ELECTROLYTIC CONDUCTIVITY DETECTOR FOR TRACE ANALYSIS OF HZ, HD, D2, AND NEON IN HYDROGEN AND DEUTERIUM” E. L. Garwin and A. Roder Stanford Linear Accelerator Center Stanford University, Stanford, California 94305 A gas chromatograph has been developed to detect traces of H2, HD, D2, and neon in hydrogen or deuterium. It uses a stainless s...

We report synthesis and transport properties of the minimal graphite intercalation compound, a ferric chloride (FeCl(3))(n) island monolayer inside bilayer graphene. Chemical doping by the intercalant is simultaneously probed by micro-Raman spectroscopy and Hall measurements. Quantum oscillations of conductivity originate from microscopic domains of intercalated and unintercalated regions. A sl...

Treatment of K562 cells with the iron chelator desferrioxamine results in the gradual increase in total cell receptors for transferrin. Receptor number rises 2.5-4.5-fold over 24 h and remains at the elevated level if the chelator is continuously present. Preincubation of the chelator with ferric chloride abolishes the effect. The drug has no effect on the 7-h half-life of the receptor. The inc...

As discharge restrictions become stricter and sludge dlisposal costs rise, traditional technologies for the removal of metals from plating shop wastewater such as lime and ferric chloride become increasingly less attractive. One technology that is of use of dithiocarbamates to complex a highly insoluble, dense sludge, effluent water and greatly reduced sludge volumes. Despite the benefits avail...

Chloroplasts may contract under natural conditions and give up water to the rest of the cell, thus indicating changes in metabolism or constitution. Such contractions may be produced experimentally. In Nitella the chloroplasts are ellipsoid bodies which, under natural conditions, may contract to spheres with a loss of volume. This may be brought about by lead acetate, ferric chloride, and digit...

I describe a simple, rapid technique for saturating the transferrin in serum and then removing unbound (excess) iron. This technique involves use of an easily prepared column of basic chromatographic alumina and a saturating solution of ferric chloride in citric acid. This method, when compared with the magnesium carbonate method of Ramsay (Clin. Chim. Acta 2: 221, 1957) by regression analysis ...

Reaction of tris(5-amino-2-ethoxy-3-isopropylphenyl)methane and pyridine-2,6-dicarbonyl-dichloride affords a multi-dentate cryptand in 48% yield. Metallation with iron(III) chloride results in a substantial conformational change of this ligand to give a trianionic triiron(III) complex. Ferric cations line the periphery of the internal cavity with each adopting a square pyramidal N(3)Cl(2) coord...
