A new carbon-nitrogen organic semiconductor has been synthesized by pyrolysis of uric acid. This layered carbon-nitrogen material contains imidazole-, pyridine (naphthyridine)- and graphitic-like nitrogen, as evinced by infrared and X-ray photoelectron spectroscopies. Quantum chemistry calculations support that it would consist of a 2D polymeric material held together by hydrogen bonds. Layers are stacked with an interplanar distance between 3.30 and 3.36 A, as in graphite and coke. Terahertz spectroscopy shows a behavior similar to that of amorphous carbons, such as coke, with non-interacting layers. This material features substantial differences from polymeric carbon nitride, with some characteristics closer to those of nitrogen-doped graphene, in spite of its higher nitrogen content. The direct optical band gap, dependent on the polycondensation temperature, ranges from 2.10 to 2.32 eV. Although in general the degree of crystallinity is low, in the material synthesized at 600 C some spots with a certain degree of crystallinity can be found.

Liquid-liquid extraction is the major technique being applied for the partitioning of f-elements from nuclear waste. In this review, the recent developments in ligand design, optimization and extraction properties are summarised for the main classes of extractants (organophosphorus ligands, diamides and N-heterocycles), with a focus on the separation of actinides and lanthanides. Structural modifications, pre-organisation and different solvent systems, as key factors for the fine-tuning of the extraction properties, are discussed. From this review, it appears that small modifications of the structure of the ligand, the pre-organising platform or the solvent can have significant impact on the extraction (and separation) of metal ions. Interest in the combinations of ligands for the extraction processes is growing, since they provide improvements over individual ligands. Similarly, unconventional approaches are being pursued to develop more efficient and greener processes.

Novel 2-naphthyridinyloxy(or thio)phenoxy propanoic acid compounds of the formula STR1 wherein STR2 represents a 6 membered nitrogen containing an aromatic ring which forms a 1,5-, 1,6-, 1,7- or 1,8-naphthyridinyl moiety with the adjoining pyridine ring, said naphthyridinyl moiety optionally substituted at the 6 position of the naphthyridinyl moiety with a chloro, bromo, iodo, CF3, or fluoro atom; A represents O or S; and agriculturally acceptable salts, esters, ethers, and amides thereof, are useful as fungicides and herbicides, particularly effective against grassy weeds.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.15936-10-4, you can also check out more blogs about15936-10-4

254-60-4, Name is 1,8-Diazanaphthalene, belongs to naphthyridine compound, is a common compound. Computed Properties of C8H6N2In an article, once mentioned the new application about 254-60-4.

Reactions of the dinuclear palladium(I) complex [Pd2Cl2(RNC)4] (R = 2,4,6-Me3C6H2) 1 with the N-donor compounds 2,2?-bipyridyl (bipy), 1,10-phenanthroline (phen), and 2,9-dimethyl-1,10-phenanthroline (dmphen) gave dipalladium(I) complexes with chelating N-donor ligands, [Pd2(RNC)2L2] [PF6]2 (L = bipy 2, phen 3 or dmphen 4). The structures of 2 and 4 were characterized by X-ray crystallography. The cation of 2 is composed of two Pd atoms joined by a sigma bond [2.518(3) A] each of which has a square-planar co-ordination involving a terminal isocyanide and a chelating bipy ligand. Complex 3 is expected to have a structure similar to 2 on the basis of spectroscopic data. Complex 4 exhibits a distorted dinuclear structure due to the steric bulk of the N-donor ligand. The Pd-Pd bond length is 2.599(2) A. Each dmphen ligand chelates to a Pd atom and the isocyanide acts as a semibridging ligand. The similar reactions of complex 1 with 2,2?-biquinoline (bquin) and 1,8-naphthyridine (napy) afforded the isocyanide-bridged dipalladium(I) complexes, [Pd2(mu-RNC)2(bquin)2]-[PF6] 2 5 and [Pd2(mu-RNC)2(napy)4][PF6] 2 6, in 24-36% yields. Complex 6 comprises a dinuclear palladium(I) core bridged by two isocyanide ligands [Pd-Pd 2.747(4) A] with four terminal napy ligands co-ordinated in a monodentate fashion.

Sludge is a by-product of wastewater treatment process with high organic and nitrogen contents. Supercritical water oxidation (SCWO) rates of refractory species in sludge might be accelerated by reactive alcohols, which is referred to as a co-oxidation phenomenon. In this work, influences of three typical reactive alcohols (methanol, ethanol and isopropanol) on TOC and of NH3?N removal rates of sludge by SCWO were analyzed and their co-oxidation products were characterized by GC?MS, FT?IR, EDS and TG?DTG methods. Additionally, to capture the nature of co-oxidation, HO2[rad] and OH[rad] radicals released by alcohols were theoretically compared with detailed chemical kinetics models using the Chemkin Software. The results show that methanol, ethanol and isopropanol all exhibited co-oxidation accelerated effects on TOC and NH3?N removal rates of sludge. One reason was that alcohols provided reactive HO2[rad] and OH[rad] radicals. The other reason was that adding alcohols not only prevented forming recalcitrant products (non-nitrogen and nitrogen aromatic compounds) but also encouraged producing reactive products (non-nitrogen open chain compounds). Ethanol offered the best co-oxidation promotion effects on the removal of TOC and NH3?N in the liquid products and also gave the lowest organic contents in the solid products, followed by isopropanol and methanol. This order was consistent with the difficulty of how the alcohols themselves could be oxidized in supercritical water since ethanol could support the highest amount of HO2[rad] radicals for sludge in the shortest time.

A series of novel 7-[3-(N?-alkoxycarbamimidoyl)-4-(alkoxyimino) pyrrolidin-1-yl] fluoroquinolone derivatives were designed, synthesized and characterized by 1H NMR, MS and HRMS. These fluoroquinolones were screened for their in vitro antibacterial activity. Most of them exhibit good potency in inhibiting the growth of Staphylococcus aureus and Staphylococcus epidermidis (MIC: 0.06-4.00 mug/mL). The activity of compounds 33 and 43 against S. aureus including MRSA and S. epidermidis including MRSE (MIC: 0.06-0.125 mug/mL) is more than or comparable to the reference drugs levofloxacin and gemifloxacin.
