Synthesis and 4f 4f absorption studies of tris(acetylacetonato) praseodymium(III) and holmium(III) complexes with imidazole and pyrazole in non-aqueous solvents. Structure elucidation by Sparkle / PM7

The complexes [Pr(acac)(3)(im)2], [Pr(acac)(3)(pz)], [Ho(acac)(3)(im)] and [Ho(acac)(3)(pz)] (acac is the anion of acetylacetone, im is imidazole and pz is pyrazole) were synthesized and characterized by elemental and thermal analyses, IR and NMR spectroscopy. The ground state molecular structures were obtained using semi-empirical Sparkle/PM7 method. The optimized structures reflect the effect of lanthanide contraction along the lanthanide series as the average Ho-O and Ho-N distances are found shorter than the average Pr-O and Pr-N distances. The size of the lanthanide also affects the overall geometry of the complex. It can be seen in the homologous [Pr(acac)(3)(pz)] and [Ho(acac)(3)(pz)] complexes with pentagonal bipyramidal (D-5h) and capped trigonal prism (C-2v) geometries, respectively. The 4f 4f absorption spectra of the complexes recorded in different non-aqueous solvents are presented and analyzed. The oscillator strength of P-3(2) -> H-3(4), D-1(2) -> H-3(4) transitions in the case of Pr(III) complexes and (5)G(6) <- I-5(8) transition in the case of Ho(III) complexes, show remarkable changes upon a change in the ancillary ligand and/or solvent. The band shape of P-3(2) <- H-3(4) transition of both the Pr(III) complexes in pyridine show remarkable change and suggests influence of pyridine in changing the inner-coordination sphere of the complexes. The band shape of the hypersensitive (5)G(6) <- I-5(8) transition of the Ho(III) complexes show appreciable change on changing the ligand/solvent. The paramagnetic shift obtained for these complexes are predominantly dipolar in nature. (C) 2019 Elsevier B.V. All rights reserved.

Simultaneous removal of pyridine and denitrification in an integrated bioelectro-photocatalytic system utilizing N-doped graphene/alpha-Fe2O3 modified photoanode

In order to realize simultaneous removal of pyridine and denitrification, an integrated bioelectrophotocatalytic system (IBPS) equipped with N-doped graphene/alpha-Fe2O3 modified graphite felt (GF) photoanode and GF biocathode was constructed and operated in ON-OFF illumination mode. Compared to alpha-Fe2O3 modified GF electrode, N-doped graphene/alpha-Fe2O3 modified photoanode showed superior stability, photo-electrochemical and catalytic activity owing to the excellent electron transporting properties of N-doped graphene and unique structure of N-doped graphene/alpha-Fe2O3 composite. In IBPS, ammonia produced from pyridine photocatalytic degradation diffused from anode to biocathode through the cation-exchange membrane. Simultaneous nitrification and denitrification were realized in the biocathode chamber under limited dissolved oxygen. At the same time, the harvested photo-electrons derived from photoanode were delivered to the biocathode via an external circuit for enhanced denitrification. Complete removal of pyridine and high TOC removal efficiency of 85.90 +/- 5.48% in the anode and complete denitrification in the biocathode after four ON-OFF cycles (96 h) reaction were achieved. Furthermore, the underlying mechanism for the enhanced removal of pyridine and denitrification was proposed preliminarily. This integrated reactor synergically utilized photoenergy, electrical energy and bioenergy for removal of pyridine and denitrification, showing a promising future in designing new systems for water environmental remediation from solar energy.

Comprehensive assessment of the effects of nitrification inhibitor application on reactive nitrogen loss in intensive vegetable production systems

Previous studies regarding environmental impacts of nitrification inhibitors (NIs) in intensive vegetable production systems mainly focused on the fate of individual nitrogen (N) compounds. Due to the influence of various N-dynamic pathways on one another, systematic observations, taking into account all key component processes, must be carried out to achieve practically useful recommendations. As well, the mechanisms of how NI application leads to increasing vegetable yields are not well understood. Therefore, we conducted a field experiment with three leading vegetable crops (lettuce, celery, and tomato), and two urea N input rates, without (N1, N2) or with a nitrification inhibitor, 2-chloro-6-(trichloromethyl)-pyridine (CP) (N1 + CP, N2 + CP), to evaluate the comprehensive effects of CP on reactive-N emission in these intensive vegetable production systems, with a focus on leaching, ammonia (NH3) volatilization, and nitrous oxide (N2O) emission, and to clarify the possible mechanisms by which CP affects vegetable yield. The results show that CP application significantly decreased (p < 0.05) N leaching by 36.9, 26.9, and 28.4 %, soil residual NO3-N contents by 34.1, 43.7, and 43.9 %, N2O emission by 46.4, 77.2, and 36.9 %, and significantly increased (p < 0.05) NH3 volatilization by 33.5, 56.3, and 308.1 % in the lettuce, celery, and tomato seasons, respectively, while having no significant effect on yield at the typical N-application rate (N2). Under 60 % of the typical N-application rate (N1), CP addition significantly increased (p < 0.05) yield and N-use efficiency (NUE) over the three-season period by 23.9 and 55.1 %, respectively, significantly reduced (p < 0.05) N2O emission by 43.5 %, while having no significant effect on the other three observed N processes. In a lettuce-celery-tomato rotation, compared with the typical N-application rate (N2), 60 % of the typical N-application rate with CP addition (N1 + CP) significantly increased (p < 0.05) yield and NUE by 37.1 and 214 %, and decreased (p < 0.05) soil residual NO3-N contents, N leaching, and N2O emission by 70.9, 51.1, and 69.6 %, respectively, and had no significant effect on NH3 volatilization. Furthermore, the distribution analysis of N derived from N-15-labeled urea in tomato aboveground suggested that CP application significantly decreased (p < 0.05) N allocation to stems and leaves by 12.1 and 9.7 %, and significantly increased (p < 0.05) N allocation to fruits by 31.2 %, averaged over 60 % and 100 % N treatments. Application of CP increased N storage in fruits and benefited yield. I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 100-54-9 help many people in the next few years. Safety of Nicotinonitrile.

Efficient Photocatalytic CO2 Reduction by a Ni(II) Complex Having Pyridine Pendants through Capturing a Mg2+ Ion as a Lewis-Acid Cocatalyst

We have synthesized a new Ni(II) complex having an S2N2-tetradentate ligand with two noncoordinating pyridine pendants as binding sites of Lewis-acidic metal ions in the vicinity of the Ni center, aiming at efficient CO production in photocatalytic CO2 reduction. In the presence of Mg2+ ions, enhancement of selective CO formation was observed in photocatalytic CO2 reduction by the Ni complex with the pyridine pendants through the formation of a Mg2+-bound species, as compared to the previously reported Ni complex without the Lewis-acid capturing sites. A higher quantum yield of CO evolution for the Mg2+-bound Ni complex was determined to be 11.1%. Even at lower CO2 concentration (5%), the Ni complex with the pendants exhibited comparable CO production to that at the CO2-saturated concentration (100%). The Mg2+-bound Ni complex was evidenced by mass spectrometry and H-1 NMR measurements. The enhancement of CO2 reduction by the Mg2+-bound species should be derived from cooperativity between the Ni and Mg centers for the stabilization of a Ni CO2 intermediate by a Lewis acidic Mg2+ ion captured in the vicinity of the Ni center, as supported by DFT calculations. The detailed mechanism of photocatalytic CO2 reduction by the Ni complex with the pyridine pendants in the presence of Mg2+ ions is discussed based on spectroscopic detection of the intermediate and kinetic analysis.

Comparative Metabolic Responses Induced by Pyridine and Imidazole in Blakeslea trispora

Lycopene cyclase needs to be inhibited by the blockers like pyridine or imidazole in the lycopene accumulation of Blakeslea trispora. This work investigated how pyridine and imidazole impacted the basal metabolism of B. trispora, the results helped us understand how they could affect the lycopene production and application, and see the metabolic risks from different inhibitors. In this study, the highest yield of lycopene with pyridine was obtained at 176 mg/L without amino acids supplement, and got more lycopene at 237 mg/L adding tyrosine, lysine, proline all together as 0.01 mol/L each in fermented broth. GC-MS and Principal Component Analysis (PCA) were used to find that amino acids, fatty acids, organic acids including phosphoric acid, carbon source and imidazole derivatives played the most important roles in lycopene fermentation with imidazole, differently, fatty acids, carbon source, and pyridine derivatives were more significant in the pyridine process and it was remarkable that the residual of both blockers’ derivatives would bring the potential risks on applications of lycopene products. Predominantly, durene met 0.35 mg/g DCW with imidazole and piperidine formaldehyde attained 0.24 mg/g DCW with pyridine after the end of lycopene fermentations.

Novel organo-osmium(ii) proteosynthesis inhibitors active against human ovarian cancer cells reduce gonad tumor growth in Caenorhabditis elegans

This work reports the synthesis and characterization of some novel osmium(ii) complexes with potential as anticancer drugs tested in vitro and in vivo. The complexes have a structure [(eta(6)-p-cym)Os(C<^>N)(X)](0/+), where the C<^>N ligand is deprotonated 2-phenylpyridine (ppy) or 4-(2-pyridin)benzaldehyde (ppy-CHO) and X is chloride, pyridine (py) or the pyridine derivative 4-NMe2-py. The in vitro cytotoxic studies showed that complexes [(eta(6)-p-cym)Os(C<^>N)(4-NMe2-py)](+) (C<^>N = ppy 2a and ppy-CHO 5a) exerted effective antiproliferative activity towards both cisplatin-sensitive ovarian cancer cells (A2780) and cisplatin-resistant cells (A2780cis). The mechanism underlying the antiproliferative effects in vitro was studied showing a reduction of proteosynthesis up to 58% and an increase of apoptosis modulated by caspase-3. Model animal Caenorhabditis elegans was used to estimate the effects of 2a and 5a and the in-house 4-NMe2-py Ru(ii) analogue 5bin vivo. Compounds 2a, 5a and 5b were able to reduce tumor growth up 32.2%, 19% and 30%, respectively in the tumoral strain JK1466 and presented low toxicity in both tumoral and wild-type strains. The mechanistic study using reporter gene expression showed that 2a, 5a and 5b were able to maintain the reactive oxygen species (ROS) levels in the animals by increased expression of the mitochondrial superoxide dismutase 3 (SOD-3), an indication that they were able to regulate oxidative stress genes specifically. Interestingly the three complexes showed a similar mechanism of action, suggesting that the identity of the metal ion does not matter and the effect is more related to the whole structure of the complex. Worthy of note, cisplatin treatment produced elevated ROS levels in the animals and induced the expression of glutathione transferase 4 (GST-4) suggesting different mechanisms of action for the two complexes. Altogether the results showed that osmium(ii) complexes can be potential candidates in the search for novel chemotherapeutic drugs.
