Interestingly, this heptazine-based polymer optically behaves as a “quasi-monomer”. In this work, we explore upstream from melem (the heptazine monomer) to the triazine-based melamine and melam and present several lines of theoretical/experimental evidence where the catalytic activity of g-CN originates from the electronic structure evolution of the C−N heterocyclic cores. Periodic density functional theory calculations reveal the strikingly different electronic structures of melem from its triazine-based counterparts. Fourier transform infrared spectroscopy and X-ray photoelectron spectroscopy also provide consistent results in the structural and chemical bonding variations of these three relevant compounds. Both melam and melem were found to show stable photocatalytic activities, while the photocatalytic activity of melem is about 5.4 times higher than that of melam during the degradation of dyes under UV−visible light irradiation. In contrast to melamine and melam, the frontier electronic orbitals of the heptazine unit in melem are uniformly distributed and well complementary to each other, which further determine the terminal amines as primary reduction sites.

The programme was subsequently expanded to include evaluations of carcinogenic risks associated with exposures to complex mixtures, lifestyle factors and biological and physical agents, as well as those in specific occupations. The objective of the programme is to elaborate and publish in the form of monographs critical reviews of data on carcinogenicity for agents to which humans are known to be exposed and on specific exposure situations; to evaluate these data in terms of human risk with the help of international working groups of experts in carcinogenesis and related fields; and to indicate where additional research efforts are needed. The lists of IARC evaluations are regularly updated and are available on the Internet athttp:// monographs.iarc.fr/. This programme has been supported since 1982 by Cooperative Agreement U01 CA33193 with the United States National Cancer Institute, Department of Health and Human Services.

Electrochemical behavior of ammeline was investigated by differential pulse polarography and cyclic voltammetry in a Britton–Robinson buffer. Optimum conditions for the analytical determination were found to be pH 9.5 at a reduction potential of –30 mV. The calibration graph was linear in the concentration range of ammeline from 0,5 μM - 39,65 μM (0.06 µg mL-1 – 4.76 µg mL-1) with a correlation coefficient of 0.998. Based on this use and under optimized conditions, with the DPP method for ammeline analysis had detection of limit (LOD) and the limit of quantification (LOQ) were obtained as 0.15 µM and 0.5 µM (0.02 µg mL-1 - 0.06 µg mL-1), respectively. This offered method has been used for the determination of ammeline in spiked milk. The result demonstrated that this method is a simple, rapid, sensitive, stable and low-cost method for ammeline detection. Keywords: ammeline, determination, polarography, milk, cyclic voltammetry 1.

Perry, Steven D. Chambreau, Ghanshyam L. Vaghjiani, and Richard N. Zare* Fuels that can be ignited chemically under ambient condi- ing the energy capacity of a fuel. Our rough measurements tions—upon contact with an oxidizing agent—are referred to indicate that about 25% of DCA IL is converted into as hypergols.[1] Engines powered by hypergols do not require precipitate during the ignition. Furthermore, the generation electric ignition, thus making them simple, robust, and of stable solid-state species during the ignition indeed reliable alternatives to conventional fossil fuels. Commonly represents a serious problem for the safe operation of used hypergolic fuels include hydrazine and its methylated bipropellant engines. The results of model experiments derivatives, which are extremely toxic, corrosive, and have obtained under various experimental conditions suggest that high vapor pressure. Intense research is underway to develop the key components necessary for the formation of the major alternative environmentally friendly liquid propellants with polymers are DCA anions and nitric acid. Polymerization lower toxicity to reduce operational costs and safety require- occurs even at lower concentration of reagents, when neither ments associated with handling hydrazine.[2] Ionic liquids hypergolic ignition nor notable heating of the reaction (ILs)[3] have recently received considerable attention as mixture take place. The reaction of DCA ILs with aqueous energetic materials for propellant applications owing to HNO3 therefore represents a new, facile, ambient method to lower vapor pressures, higher densities and, often, an synthesize cyclic azines, which can be tuned by choosing from enhanced thermal stability compared to their nonionic a variety of different IL precursors.
