  • Elaborating the Link Between VSEPR and Orbital Hybridization

    • Abstract: Many undergraduate chemistry textbooks discuss both the VSEPR (valence-shell electron-pair repulsion) and hybridization (the mixing of atomic orbitals to form new directional orbitals) models of molecular structure as separate topics and fail to mention Bent’s rule (the more electronegative ligand uses the hybrid bonding orbital with the greatest p-character). In this paper, important, but neglected, correlations among these three topics are explored. In addition, it is shown how a consideration of these correlations makes each of the topics more understandable to students.

  • Using Mean Oxidation Number of Organic Carbons to Quantify Buswell’s
           Equation

    • Abstract: Buswell’s equation can represent anaerobic digestion. The overall stoichiometric chemical equation is important for the counting of biomethane and theoretical biochemical methane potential. Although the concept of oxidation number of organic carbons has been applied in organic chemistry and biochemistry, the relationship between mean oxidation number of organic carbons and quantity of biomethane has not been studied. This article uses the H-atom method as a balancing tool to build a Buswell’s model which can help understand the redox nature of organic compounds and establish the mathematical relationships among the stoichiometric coefficients of Buswell’s equation, elemental composition of organic compound, and mean oxidation number of organic carbons. By using mean oxidation number of organic carbons as a metric, the mathematical equations for the counting of biomethane and theoretical biochemical methane potential are attained. The parameters of Buswell’s equation can also be quantified by any given structural formula of an organic compound.

  • New Method for Analyzing Tyramine by Spectrofluorimetry: Application to
           Fish

    • Abstract: A new method for direct spectrofluorimetric analysis of tyramine in various fish samples was established. Low limits of detection (LOD) between 0.53 ng/mL and 1.40 ng/mL and limits of quantification (LOQ) between 1.76 ng/mL and 4.68 ng/mL were obtained. Also, low values of relative standard deviations (RSD) between 0.30 % and 0.58 % were obtained; confirming good reproducibility of our measurements. The application of this method to our samples allowed the detection of tyramine with satisfactory recovery rates between 93.68 % and 106.60 %. Interference studies with different biogenic amines have shown that the determination of tyramine can be done without major problems in the presence of spermine, spermidine, and histamine. However, special attention should be paid when tyramine is determined in the presence of agmatine, cadaverine or putrescine. In all cases, the determination of tyramine is more influenced by the presence of tryptamine or dopamine in the sample.

  • Mean Oxidation Number of Organic Carbons for Quantifying Biomethane in
           Organophosphorous Compounds

    • Abstract: Anaerobic digestion is a complex biochemical process in which organic matters are mineralized and stabilized into biogas and digestate by microorganisms in the absence of oxygen. Buswell’s equation is an ideal model to represent anaerobic digestion for counting theoretical quantity of biogas and digestate in organic matters. Although the degradability and recovery of phosphorous element in digestate have been studied, the impact of phosphorous element on quantity of biomethane and theoretical biomethane potential in organophosphorous compounds are rarely explored. The quantity of biomethane is dependent on the elemental composition of organic matters, and the mean oxidation number of organic carbons is used as a counting parameter in Buswell’s equation. Biowastes which contain organophosphorous compounds are chosen to demonstrate this notion. This article has two purposes. First, the mathematical relationships among empirical formula of organic matter, mean oxidation number of organic carbons, quantity of biomethane, and theoretical biomethane potential are explored. Second, the impact of quantity of phosphorous element on quantity of biomethane, theoretical biomethane potential, and the ratio of biomethane to carbon dioxide are studied.

  • Crystal Growth and Structure of NiC4H4O6·2.5H2O

    • Abstract: Single crystals of nickel tartrate hemi-pentahydrate, NiC4H4O6·2.5H2O, were grown by the gel method using silica gels. The crystal structure was determined by the single-crystal X-ray diffraction method. Its structure was orthorhombic with space group P212121 and lattice constants a = 7.8578(3) Å, b = 11.0988(5) Å, and c = 18.0529(8) Å, and consisted of slightly distorted NiO6 octahedra, C4H4O6 and H2O molecules, C4H4O6–Ni–C4H4O6 chains containing H2O molecules, and O–H···O hydrogen-bonded frameworks between adjacent molecules. The C4H4O6 molecules contained both single and double C–O bonds, and single C–C bonds, similar to other tartrate compounds. We discussed the differences in the chemical formulae and structures of tartrate compounds induced by different cations of the first transition metal series.
