Spectrophotometric Determination of Microgram Quantities of Copper in Biologic Materials.
A procedurefor the determination of microgramquantities of copper in biologicmaterial is described. The sample is wet-ashed with a nitric acid-perchloric acid mixture. The copper is extracted from an alkaline solutionof the ash with a solutionof diphenylcarbazide in benzene. Absorbanceof the red complex is read at 540 m1&. The copperin as little as0.5 ml. of serum can be determined and the meth...
متن کاملSequential Voronoi Diagram Calculations using Simple Chemical Reactions
In the authors’ recent paper (de Lacy Costello et al., 2010) the authors described the formation of complex tessellations of the plane arising from the various reactions of metal salts with potassium ferricyanide and ferrocyanide loaded gels. In addition to producing colourful tessellations these reactions are naturally computing generalised Voronoi diagrams of the plane. The reactions reported...
متن کاملDetection of bond formations by DNA-programmed chemical reactions and PCR amplification.
A system capable of performing both DNA-templated chemical reactions and detection of bond formations is reported. Photocleavable DNA templates direct reactions. Products from bond-forming events re-ligate original templates, amplifiable by PCR, therefore distinguishing bond formation from background. This system provides a novel approach for discovering potential new chemical reactions.

متن کاملPlasmon-driven sequential chemical reactions in an aqueous environment
Plasmon-driven sequential chemical reactions were successfully realized in an aqueous environment. In an electrochemical environment, sequential chemical reactions were driven by an applied potential and laser irradiation. Furthermore, the rate of the chemical reaction was controlled via pH, which provides indirect evidence that the hot electrons generated from plasmon decay play an important r...
