  • Patent number: 8753997
    Abstract: The use of fuel cells to produce electricity are known as an environmentally clean and reliable source of energy, and show promise as an automotive power source if the polymer electrolyte membrane fuel cell can be made less expensive, more durable, reduce or eliminate humidification of the reactive gases, and operate at temperatures encountered during automotive operating conditions. The use of an electro-catalyst formed from heteropoly acids immobilized by a conductive material, such as carbon or platinum black, and stabilizing a metallic black with the immobilized conductive material addressed these automotive fuel cell needs. Coating the fuel cell electrode, polymer electrolyte assembly with a nano-particle catalyst derived from a heteropoly acid provided anodic carbon monoxide tolerance at anodic overpotentials and an active cathodic oxygen reduction. The heteropoly acids can also function as supercapacitor electrode films.

  • Patent number: 7025904
    Abstract: Flexible and semi-rigid vinyl chloride resin compositions comprising a combination of a latent mercaptan and a zinc salt of oxidized polyethylene (a zinc ionomer) as a heat stabilizer are substantially free from the offensive odor typically associated with mercaptans and are protected during processing by the degradation products of the latent mercaptan and the zinc ionomer. The oxidized polyethylene is split out from the ionomer to act as an adhesion promoter for aqueous inks and paints, and the residual zinc carboxylate functions as a co-stabilizer with the latent mercaptan in the composition. The latent mercaptan is exemplified by a 2-S-(tetrahydropyranyl)thioalkanol, a carboxylic acid ester thereof, a 2-S-(tetrahydropyranyl)-thiocarboxylic acid, an ester thereof, and the furanyl homologs of each.

  • Patent number: 6610218
    Abstract: Halogen-containing polymer compositions comprising a latent mercaptan-containing heat stabilizer composition substantially free from the offensive odor typically associated with mercaptans are protected during processing by the degradation products of the latent (i.e., blocked) mercaptan which include a free mercaptan. Other products of the degradation are believed to include carbocations of the blocking moiety which are stabilized by a molecular structure in which the electron deficiency is shared by several groups. The latent mercaptan may be the sole heat stabilizer additive but the free mercaptan released during processing may also synergize the activity of metal-based heat stabilizers such as metal salts and organometallic stabilizers such as organotin carboxylates and mercaptides in the polymer composition. The odor of primary mercaptan-containing heat stabilizers in halogenated polymer compositions is masked by a small amount of a latent mercaptan.

  • Patent number: 5446186
    Abstract: The synthesis and compound of a new caged calcium which is an ortho-nitrophenyl derivative of EGTA and various intermediates. It is synthesized in ten steps and 24% overall yield. The photosensitive chelator, nitrophenyl-EGTA, has a K.sub.d for Ca.sup.2+ of 80 nM and for Mg.sup.2+ of 8.8 mM. Upon exposure to ultra-violet light (in the region of 350 nm), the chelator is cleaved, yielding iminodiacetic acid photoproducts with known low Ca-affinity (K.sub.d =1 mM). The quantum yield of photolysis of nitrophenyl-EGTA in the presence of Ca.sup.a+ is 0.23 and in the absence of Ca.sup.2+ is 0.20. In experiments with chemically skinned skeletal muscle fibers, a fully relaxed fiber equilibrated with nitrophenyl-EGTA:Ca.sup.2+ complex, in the presence of physiological [Mg.sup.2+ ] (i.e. 1.0 mM), produced maximal contraction after a single flash from a frequency doubled ruby laser (347 nm). Half-maximal tension was achieved in 18 ms at 15.degree. C.
