Increasing attention has been given to the control of nitrogen pollutants during the process of using sewage sludge. In this paper, the gasification characteristics and the law of nitrogen migration in the process of chemical looping gasification (CLG) of sewage sludge were explored. Copper slag calcined at 1100 degrees C (1100CS), FeAl (Fe2O3+Al2O3), NiFeAl (NiFe2O4+Al2O3), and NiAl (NiO + Al2O3) were used as oxygen carrier. The addition of an oxygen carrier could increase the carbon conversion rate and decrease the low heating value. NOx precursors (HCN and NH3) were the main nitrogen-containing gas pollutants (similar to 40%). The sum yield of char nitrogen and tar nitrogen was only similar to 10%. Nitrile nitrogen, heterocyclic nitrogen and amide nitrogen were the main nitrogenous compounds in tar nitrogen. Increasing the oxidative activity of the oxygen carrier could significantly promote the oxidative transformation of N-2 from the NOx precursors, tar nitrogen, char nitrogen. Additionally, the migration of fuel nitrogen includes synchronous autothermal pyrolysis (stage I) and oxidative pyrolysis of the three-phase product under the action of [O] (stage II). Finally, this research realizes the energy utilization of sludge and reduces the release of nitrogen pollutants. (C) 2020 Elsevier Ltd. All rights reserved.

Adsorption using nanomaterials is considered an effective method for controlling the levels of toxic heavy metal in wastewater. Herein, a novel adsorbent, core-shell phase-transited lysozyme film-coated magnetic nano particles (Fe3O4@SiO2@PTL) for Hg(II) ions removal from aqueous solutions was explored via facile and fast phase transformation and self-assembly process of lysozyme. The physiochemical properties of Fe3O4@SiO2@PTL were investigated using various characterization techniques. The adsorption performances such as kinetics, isotherms, selectivity, the effect of coexisting ions, and regeneration were evaluated. Fe3O4@SiO2@PTL showed an extremely high Hg(II) uptake rate and achieved more than 90% equilibrium adsorption capacity in 5 min. Hg(II) adsorption was followed by a pseudo-second-order kinetic model and fitted the Langmuir model by achieving a maximum uptake of 701.51 mg/g. Furthermore, excellent Hg(II) selectivity was obtained in a mixed solution containing various heavy metal ions, along with good chemical stability owing to the high adsorption capacity maintained after five cycles. The adsorption analyses indicated that the amino, imino, amide, hydroxyl, carboxyl, and thiol groups exposed on the surface of Fe3O4@SiO2@PTL were vital for Hg(II) removal. Consequently, this work will significantly assist in the development of an easily available, eco-friendly, and selective adsorbent material to remove heavy metal ions from wastewater.

The absolute configurations of the separated enantiomers of fluralaner, a racemic animal health product used to prevent fleas and ticks, have been assigned using vibrational circular dichroism (VCD). The crystallographic structure of the active enantiomer (+)-fluralaner has previously been shown to have the (S) configuration using small molecule crystallography. We sought a faster analytical method to determine the absolute configuration of the separated enantiomers. When comparing the measured IR (infrared) and VCD spectra, it is apparent that the amide carbonyl groups appear in the IR but are nearly absent in the VCD. Computational work to calculate the VCD and IR using in vacuo models, implicit solvation, and explicitly solvated complexes has implicated conformational averaging of the carbonyl VCD intensities.

A novel hybrid CHC was designed and synthesized by conjugating beta-carboline with an important active fragment N-hydroxyacrylamide of histone deacetylase (HDAC) inhibitor by an amide linkage to enhance antitumor efficacy/potency or even block drug resistance. CHC displayed high antiproliferative effects against drug-sensitive SUMM-7721, Bel7402, Huh7, and HCT116 cells and drug-resistant Bel7402/5FU cells with IC50 values ranging from 1.84 to 3.27 mu M, which were two-to four-fold lower than those of FDA-approved HDAC inhibitor SAHA. However, CHC had relatively weak effect on non-tumor hepatic LO2 cells. Furthermore, CHC exhibited selective HDAC1/6 inhibitory effects and simultaneously augmented the acetylated histone H3/H4 and alpha-tubulin, which may make a great contribution to their antiproliferative effects. In addition, CHC also electrostatically interacted with CT-DNA, exerted remarkable cellular apoptosis by regulating the expression of apoptosis-related proteins and DNA damage proteins in Bel7402/5FU cells, and significantly accumulated cancer cells at the G2/M phase of the cell cycle by suppressing CDK1 and cyclin B protein with greater potency than SAHA-treated groups. Finally, CHC displayed strong inhibitory potency to drug-resistant hepatic tumors in mice. Our designed and synthetic hybrid CHC could be further developed as a significant and selective anticancer agent to potentially treat drug-resistant hepatocellular carcinoma.

The coordination chemistry of PdmBOX [2,5-bis(2-oxazolinyldimethylmethyl)pyrrole] pincer ligands, in which a dimethylmethylidene linker has been introduced to preclude rearrangements in the backbone, has been studied with 3d and 4d late transition metals. The in situ lithiated PdmBOX ligand was treated with MnCl2, FeCl2 and CoCl2 to give [(iPr)(PdmBOX)MCl] (M = Mn: 2; Fe: 3; Co: 4) which were found to adopt a distorted tetrahedral coordination geometry in the crystal. Addition of 2,6-dimethylphenylisocyanide to 3 gave the diamagnetic tris(isocyanide) derivative [(iPr)(PdmBOX)Fe(CNxyl)(3)]Cl (5) with the chloride as the counteranion. Complexes 2-4 were found to be precatalysts for the enantioselective hydrosilylation and hydroboration of acetophenone. The synthesis of PdmBOX-palladium(II) complexes was achieved by deprotonation of the protioligand with potassium bis(trimethylsilyl)amide (KHMDS) and subsequent reaction with [(cod)PdCl2] giving [(iPr)(PdmBOX)PdCl] (6) or by stirring (S)-(iPr)(PdmBOX)H with palladium acetate yielding the palladium acetato complex 7. Treatment of the latter with phenylsilane at 60 degrees C also led to the slow formation of the metal hydride complex which was the key species in the catalytic hydrosilylation of styrene oxide, albeit with low activity. The coordination of (S)-(iPr)(PdmBOX)H to rhodium(I) was accomplished by reaction with (acetylacetonato)dicarbonylrhodium(I) to give the corresponding PdmBOX-Rh complex 8 which reacted with methyl iodide to give the octahedrally coordinated rhodium(III) complex [(iPr)(PdmBOX)Rh(CH3)I(CO)] 9. Reaction of 8 with one equivalent of CsBr3 led to the full conversion to the dibromorhodium(III) complex [(iPr)(PdmBOX)Rh(CO)Br-2] 10. Upon reaction of 10 with N-bromosuccinimide (NBS), the pyrrole backbone in 10 was brominated to give complex 11. In a similar way, a selective conversion of [(iPr)(PdmBOX)NiCl] to the backbone-chlorinated [(iPr)((Cl)PdmBOX)NiCl] (12) was achieved by the treatment with N-chlorosuccinimide.

You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 98-79-3, Name is H-Pyr-OH, molecular formula is , belongs to amides-buliding-blocks compound.

Charge-transfer (CT) gel materials obtained from low-molecular-weight (LMW) compounds through a supramolecular self-assembly approach have received fascinating attention by many researchers because of their interesting material property and potential applications. However, most of the CT gel materials constructed were of organogels while the construction of CT gels in the form of a hydrogel is a challenge because of the solubility issue in water, which considerably limits the use of CT hydrogels. Herein, for the first time, we report a new LMW gelator [Na-alpha-fluorenylinethoxycarbonyl)-N-epsilon-(delta-butyric-1-pyrenyl)-L-lysine, (FmKPy)], composed of two functional moieties such as fluorenylmethoxycarbonyl and pyrene, which not only parade both hydro and organo (ambidextrous) supramolecular gel formation but also exhibit CT ambidextrous gels when mixed with an electron acceptor such as 2,4,7-trinitro-9-fluorenone (TNF). This finding is significant as the established CT organogelator in the literature did not form an organogel in the absence of an electron acceptor or lose their gelation property upon the addition of the acceptor. CT between pyrene and TNF was confirmed by the color change as well as the appearance of the CT band in the visible region of the absorption spectrum. CT between FmKPy and TNF was supported by the solvent dilution method using tetrahydrofuran as the gel breaker and pyrene fluorescence quenching in the case compound containing pyrene and TNF. The morphology of FmKPy ambidextrous gels indicates the fibrous nature while the self-assembled structure is primarily stabilized by pi-pi stacking among fluorenyl and pyrenyl moieties and hydrogen bonding between amide groups. The FmKPy-TNF CT ambidextrous gel retains the fibrous nature; however, the size of the fibers changed. In FmKPy-TNF CT gels, TNF is intercalated between pyrene moieties in the self-assembled structure as confirmed by fluorescence quenching and powder X-ray diffraction. The FmKPy ambidextrous gel exhibits significant properties such as low minimum gelation concentration (MGC), thixotropic nature, pH stimuli response, and high thermal stability. Upon the addition of TNF, the FmKPy-TNF CT ambidextrous gel maintains all these properties except MGC which increased for FmKPy-TNF. Because pyrene-based LMW organogels have been developed widely for many applications while their hydrogels were limited, the current finding of the pyrene-based ambidextrous fluorescent gel with the CT property provides a wide opportunity to use FmKPy as a soft material maker and also for potential applications in fields like surface coating, three-dimensional printing, and so forth.
