Nitric Oxide (NO) separation from flue gas by chemical modified mesoporous silica

Three kinds of chemically modified silica were prepared to adsorb NO by surface modifying with vinyltriethoxysilane, acrylic acid and acryl amide respectively, and characterized by N-2 adsorption experiments, Fourier transform infrared spectroscopy, scanning electron microscopy and thermo-gravity analysis. The results showed that -COOH and -CONH2 in the monomers had been grafted on the silica surface, and the pore volumes of S-1, S-2 and S-3 decreased and exhibited the mesoporous structure; all the modified adsorbents could maintain steady under 300 degrees C. NO adsorption experiments were also carried out and the results suggested that the silica modified with acryl amide had the best NO adsorption capacity due to the relative large surface area and the stronger hydrogen bonds between NO molecules and the functional groups. The adsorbed NO molecules could be well desorbed by purging with N-2 so that the adsorbents could be recycled and NO resource also had the chance to be reused.

Development of an analytical methodology for the analysis of priority cytostatics in water

The consumption of cytostatics has remarkably increased over the last years due to the high cancer incidence worldwide. In previous studies, seven cytostatics were already recognized to potentially induce chronic effects in aquatic organisms, taking into account their estimated concentrations in surface waters: cyclophosphamide (CYC), capecitabine (CAP), mycophenolic acid (MPA), imatinib (IMA), bicalutamide (BICA), prednisone (PRED) and 5-fluorouracil (5FU). The objective of the present study was to simultaneously analyse these 7 prioritized compounds, which have the highest chances to be found in surface and wastewaters. The analytical challenge relies in the determination of these very polar compounds, which have different chemical and structural properties. Solid-phase extraction with an Ultra Performance Liquid Chromatograph-Mass Spectrometer in electrospray ionization mixed mode (5-fluorouracil and bicalutamide in negative mode and the others in positive one) was developed to determine seven cytostatics in wastewater and surface water. Among eight tested cartridges with different sorbents and conditions, the best extraction performance was attained with Oasis WAX at pH 10, with recoveries ranging from 31 +/- 4 (5FU) and 103 +/- 17% (MPA). Regarding the chromatographic analysis, the best results were achieved with an XBridge amide column. The final analytical methodology was successfully applied for the analysis of real water samples, confirming the presence of risky cytostatics in surface and wastewaters. (c) 2018 Elsevier B.V.

Chromium(VI) concurrent detoxification and immobilization by gallate: Kinetics, equilibrium, thermodynamics, and mechanism studies

Gallic acid (GA), with a reducing and in situ coordinating capability towards to reducible metal ions, was successfully conjugated onto the amine-silane coated magnetite nanoparticles by stable amide bond through 1ethyl-3-(3-dimethylaminepropyl) carbodiimide hydrochloride/N-hydroxysuccinimide (EDC/ NHS) chemistry, with the aim of engineering a magnetically-separable Fe3O4@ TEOS@ AMEO@ GA applicable for Cr(VI) concurrent reduction and removal, together with explicating reduction-adsorption mechanism. The structure, composition, and morphology of the nanocomposite were systematically characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), atomic force microscope (AFM), low-temperature nitrogen adsorption/desorption experiment, X-ray spectroscope (EDS), X-ray photoelectronic spectroscopy (XPS), Fourier transform infrared spectroscopy (FTIR), total organic carbon (TOC), X-ray diffraction (XRD), vibrating sample magnetometer (VSM), and fluorescence spectra, showing a core-shell, cubic inverse spinel structure of the nanocomposite with superparamagnetism roughly containing 7.8% (w/w) GA on its surface. Cr (VI) reduction-adsorption kinetics, equilibrium, and thermodynamics studies were carried out under solution pH of 6.0, where partially deprotonated phenolic hydroxyl dominated the nanoadsorbent surface. Results showed that pseudo-first order kinetic model and Freundlich isotherm model described the Cr(VI) reduction-adsorption well. Thermodynamics studies indicated an endothermic, spontaneous, and feasible process of such Cr(VI) reduction- adsorption. Furthermore, Cr(VI) reduction-adsorption mechanism was explicated by EDS and XPS technology, finding that phenolic hydroxyls of those conjugated gallates were only functional and active groups. Based on these, we intend to offer a predictable, and hence controllable approach for Cr(VI) reductive immobilization that may be a potential direction for those poisonous and reducible metal ions thorough detoxification and in situ removal based on magnetite-supported materials in practical application.

Hybrid inorganic (nonporous silica)/organic (alginate) core-shell platform for targeting a cisplatin-based Pt(IV) anticancer prodrug

Nonporous silica nanoparticles with an external shell containing the 3-aminopropyl arm (SiNP) were further decorated with alginic acid (SiNP-ALG) as a potential biocompatible delivery system for Pt antitumor agents. Such particles were coupled with the prodrug (0C-6-44)-acetato(beta-alaninato)diamminedichloridoplatinum(IV), 1, through the formation of amide bonds between the pendant carboxylate groups on SiNP-ALG and the free amino group of the complex. Cytosol extracted from tumor cells was able to quickly and efficiently reduce the Pt (IV) prodrug, and produces the active metabolite cisplatin. SiNP-ALG-Pt conjugate was more active than both cisplatin and 1, due to its more efficient cell uptake, whereas the SiNP-ALG unplatinated nanoparticles were deprived of any nonspecific toxicity.

N-(substituted phenyl)-2-chloroacetamides: LSER and LFER study

The UV absorption spectra of twelve N-(substituted phenyl)-2-chloroacetamides were recorded in eighteen solvents. The effect of specific and non-specific solvent-solute interactions on the absorption maxima shifts was evaluated by using the Kamlet-Taft solvent parameter set, i.e. applying linear solvation energy relationships (LSER) principles. Optimized geometries and experimental results were interpreted by using DFT (B3LYP/6-311+G(d,p) method) and time-dependent density functional (TD-DFT) method. Overall electron density in both ground and excited state was obtained by the use of Quantum Theory of Atoms in Molecules, i.e. Bader’s analysis. It was found that both solvent and substituents cause appropriate change of the extent of conjugation in the molecules that further affect their intra-molecular charge transfer (ICT) character. Linear free energy relationships (LFERs) were applied to the substituent-induced NMR chemical shifts (SCS) using single substituent parameter (SSP) and dual substituent parameter (DSP) model. Transmission mode of the electronic effects of substituent was discussed according to the results of theoretical calculations and results of LFER correlations. Comparative analysis of presented results with the ones published for structurally similar series of amide which contained cyano group, instead chlorine, provides additional information on the impact of present group to the properties of investigated compound.

Glucagon-like peptide-1 cleavage product GLP-1 (9-36) amide enhances hippocampal long-term synaptic plasticity in correlation with suppression of Kv4.2 expression and eEF2 phosphorylation

Glucagon-like peptide-1 (GLP-1) is an endogenous gut hormone and a key regulator in maintaining glucose homeostasis by stimulating insulin secretion. Its natural cleavage product GLP-1 (9-36), used to be considered a bio-inactive metabolite mainly because of its lack of insulinotropic effects and low affinity for GLP-1 receptors, possesses unique properties such as anti-oxidant and cardiovascular protection. Little is known about the role of GLP-1 (9-36) in central nervous system. Here we report that chronic, systemic application of GLP-1 (9-36) in adult mice facilitated both the induction and maintenance phases of hippocampal long-term potentiation (LTP), a major form of synaptic plasticity. In contrast, spatial learning and memory, as assessed by the Morris water maze test, was not altered by GLP-1 (9-36) administration. At the molecular level, GLP-1 (9-36) reduced protein levels of the potassium channel Kv4.2 in hippocampus, which is linked to elevated dendritic membrane excitability. Moreover, GLP-1(9-36) treatment inhibited phosphorylation of mRNA translational factor eEF2, which is associated with increased capacity for de novo protein synthesis. Finally, we showed that the LTP-enhancing effects by GLP-1 (9-36) treatment in vivo were blunted by application of exendin(9-39)amide [EX(9-39)], the GLP-1 receptor (GLP-1R) antagonist, suggesting its role as a GLP-1R agonist. These findings demonstrate that GLP-1 (9-36), which was considered a bio-inactive peptide, clearly exerts physiological effects on neuronal plasticity in the hippocampus, a brain region critical for learning and memory.

Sustainable corrosion inhibitor for steel in simulated concrete pore solution by maize gluten meal extract: Electrochemical and adsorption behavior studies

The corrosion inhibitive effect of maize gluten meal extracts for steel in simulated concrete pore solution with 3.0 wt% sodium chloride was investigated. The results acquired from EIS and polarization studies were in a good agreement, which suggest an increase in the corrosion resistance of steel with the extract introduced comparatively to the blank systems. Adsorption of extracts onto the steel surface obeyed the isothermal Langmuir adsorption, was mainly controlled by physisorption. The confirmatory evidence of enhanced corrosion resistance during adsorption was obtained from the SEM-EDS, ATR-FTIR and surface structure analysis. Furthermore, the amide bond structures of the main constituents in extract were also beneficial to adhere to steel surface. The sustainable extract of maize gluten meal is a by product of starch industry, which is an effectively and promisingly inhibitor for reinforced steel with the anticorrosion efficiency of 62.71-88.10%.
