Aminotriazole isomers modified cellulose microspheres for selective adsorption of U(VI): Performance and mechanism investigation

Aminotriazole isomers with high nitrogen content show potential affinity for U(VI). Combining the advantages of both aminotriazole and cellulose, two n-aminotriazole isomers modified cellulose microspheres (n-ATARs, n = 3, 4) were newly prepared as adsorbents via radiation technology. Batch adsorption experiments showed that n-ATARs possessed good adsorption capacity of U(VI) in the order of 3-ATAR > 4-ATAR, and the adsorption process followed the Langmuir-Freundlich isotherm model and the pseudo-second-order kinetic model. Both n-ATARs exhibited good selectivity and reusability. Besides, 3-ATAR and 4-ATAR were more suitable for the extraction of trace amount of U(VI) from the contaminated groundwater and the simulated seawater, respectively. The effect of amino position on triazole ring on adsorption behavior of n-ATAR was studied and explained by DFT calculation. Finally, the adsorption mechanism of U(VI) onto n-ATARs was revealed to be inner-sphere complexation via different 1:1 or 1:2 coordination models by FTIR, MS, XPS analysis and DFT calculation.

Slow Magnetic Relaxation in a [Na2Dy4] Complex and Coexistence of Multiple Metal Rings

Three rare isostructural heterometallic complexes [Na-2{Ln(4)(mu(3)-OH)(2)(ppt)(4)(Hppt)(2)(OAc)(2)}(DMF)(4)] . xH(2)O (H(2)ppt=3-(2-hydroxyphenyl)-5-(pyrazin-2-yl)-1,2,4-triazole, x=2.5, Ln=Dy (1); x=2, Ln=Er (2); x=0, Ln=Yb (3)) have been obtained. The structural analysis displayed that two Na-I and four Ln(III) ions were linked together through N-N groups and O atoms to form a metallmacrocycle with the connectivity pattern [Dy-O-Na-N-N-Dy-O](2). Such cases possess rare hexametallic ring, which further displays one tetrametallic and two trimetallic cyclic units. Magnetic measurements reveal single-molecule magnet (SMM) behavior for 1 with the effective energy barrier of 51.6 K and pre-exponential factor of 6.16×10(-6) s deduced from frequency-dependent magnetic susceptibilities. Ab initio calculations prove that the weak ferromagnetic coupling mainly originats from the dipolar interaction. The transversal magnetic moments in the ground Kramers could suppressed the quantum tunneling of magnetization.

Rheological non-isothermal mechanistic investigation on the curing of glycidyl azide polymer with solid nanofillers

The effects of ammonium perchlorate (AP) and graphene oxide (GO) on the curing of glycidyl azide polymer (GAP) were investigated. The rheological parameters of GAP crosslinked by bispropargyl succinate (BPS) were investigated by rheometry instrument. The curing kinetics by the differential isoconversional method revealed that AP (1 wt%) increased the apparent activation energy from 72.98 to 76.41 kJ mol(-1). However, the presence of GO (0.1 wt%) catalyzed the curing of GAP/triazole by decreasing the apparent activation energy to 62.86 kJ mol(-1). The physical models revealed that the addition of GO changed the cure mechanism of GAP/BPS as it acted as new nucleation sites. The Fourier-transform infrared (FTIR) and X-ray photoelectron (XPS) results also showed that chemical groups on the surface of GO reacted with the hydroxyl groups of GAP, which changed the curing mechanism of GAP/BPS and improved the tension strength of the propellant by 104%.

Efficient copper-catalyzed tandem oxidative iodination and alkyne-azide cycloaddition in the presence of glycine-type ligands

Tandem oxidative iodination and alkyne-azide cycloaddition reaction has provided one of the most widely used methods for preparation of 5-iodo-1,2,3-triazoles. However, stoichiometric copper salts are involved in this type of reaction in order to enhance the reaction effectiveness, which caused some problems related to toxic metal contaminations and less sustainability. In this paper, we described that a copper-catalyzed (10 mol%) tandem oxidative iodination and alkyne-azide cycloaddition could be completed in the presence of the newly-found glycine-type ligands with low-cost Nal as the iodine resource. In the novel reaction system, a wide range of terminal alkyne, organic azide and inexpensive iodide could react effectively in one pot to give structurally diverse 5-iodo-1,4-subsitutied 1,2,3-triazoles. Natural product derivatives and alkynyl pyridines that hardly react under traditional conditions could also be transferred smoothly to the target products for the first time. (C) 2020 Elsevier Ltd.

Solvothermal preparation of luminescent zinc(II) and cadmium(II) coordination complexes based on the new bi-functional building block and photo-luminescent sensing for Cu2+, Al3+ and L-lysine

In industry, over usage of Cu2+ and Al3+ will lead to toxic wastewater, which further to give serious pollution for the environment. On the other hand, L-lysine can enhance serotonin release in the amygdala, with subsequent changes in psychobehavioral responses to stress. Therefore it is the urgent problem to design a method for detecting the amount of Cu2+, Al3+, and L-lysine. In this work, through the solvothermal synthesis method, two new coordination complexes based on the new bifunctional building block 4′-(1H-1,2,4-triazole-1-yl)- [1,1′-biphenyl]-4-carboxylic acid (HL) have been synthesized, namely, [Zn(L)(2)center dot 4H(2)O] (complex 1) and [Cd(L)(2)center dot 4H(2)O] (complex 2). X-ray single-crystal diffractometer was used to analyze its structure, powder X-ray diffraction (PXRD) patterns confirmed that 1 and 2 powder’s purity and 1 can keep stable during the detection process of Cu2+, Al3+, and L-lysine, respectively. Elemental analysis, thermogravimetric analysis, infrared analysis, ultraviolet analysis and fluorescent spectrum have been used to characterize these complexes. The photo-luminescent test showed that 1 can accurately recognize Al3+ and Cu2+ among various cations. On the other hand, 1 can distinguish L-lysine among amino acid molecules. Therefore, 1 can be utilized as a multifunctional fluorescent probe for Al3+ (K-sv = 1.5570 x 10(4) [M](-1)), Cu2+ (K-sv = 1.4948 x 10(4) [M](-1)) and L-lysine (K-sv = 4.9118 x 10(4) [M](-1)) with low detection limits (17.5 mu M, 18.2 mu M, 5.6 mu M) respectively.

A new imidazolium/sulfonamide linked ferrocene-dansyl dyad for dual-channel recognition of anion

A new ferrocene-dansyl dyad (Fc-DAS), in which the ferrocene unit and the dansyl fluorophore are linked by the imidazolium and the sulfonamide groups, has been designed. The recognition ability of probe toward various anions (H2PO4-, F-, Cl-, Br-, I- and AcO-) has been investigated by fluorescent spectrum and electro-chemical techniques (differential pulse voltammetry and cyclic voltammetry). This probe shows fluorescent sensing of F- over other anions with a quenching effect in CH3CN solution. However, the electrochemical experiments reveal that the binding of H2PO4-, F- and AcO- anions leads the potential of probe a cathodic shift, with the shift magnitude H2PO4- > F- > AcO-. Furthermore, the binding mechanisms between Fc-DAS and anions have been investigated using H-1 NMR titration and density functional theory (DFT) calculations.

Developmental reproductive toxicity and endocrine activity of propiconazole in the Xenopus tropicalis model

Environmental pollutants and especially endocrine disrupting chemicals (EDCs) are implicated as one of the drivers of the amphibian declines. To advance the understanding of the risks of EDCs to amphibians, methods to determine endocrine-linked adverse effects are needed. The aims were to 1) develop a partial life-cycle assaywith themodel frog Xenopus tropicalis to determine endocrine perturbation and adverse developmental effects, and 2) determine effects of propiconazole in this assay. Propiconazole is a pesticidewithmultiple endocrine modes of action in vitro. Its potential endocrine activity and adverse effects in amphibians remain to be elucidated. Tadpoles were exposed to 0, 33 and 384 mu g propiconazole/L during critical developmental windows until completed metamorphosis. At metamorphosis, a sub-sample of animals was analysed for endpoints for disruption of estrogen/androgen (sex ratio, brain aromatase activity) and thyroid pathways (time to metamorphosis). The remaining individuals were kept unexposed for 2 months post-metamorphosis to analyze effects on sexual development including gonadal and Mullerian duct maturity and gametogenesis. At metamorphosis, brain aromatase activity was significantly increased in the high-dose group compared to control. In both propiconazole groups, an increased proportion of individuals reached metamorphosis faster than the mean time for controls, suggesting a stimulatory effect on the thyroid system. At 2 months post-metamorphosis, testis size, sperm and Mullerian duct maturity were reduced in the low-dose males, and the liver somatic index in males was increased in both propiconazole groups, compared with controls. In conclusion, our results show that propiconazole exposure caused endocrine perturbations and subsequent hepatic and reproductive effects evident at puberty, indicating persistent disruption of metabolism and male reproductive function. Our findings advance the development of methodology to determine endocrine and adverse effects of EDCs. Moreover, they increase the understanding of endocrine perturbations and consequent risk of adverse effects of azoles in amphibians. (C) 2020 The Authors. Published by Elsevier B.V.

A robust heterogeneous Co-MOF catalyst in azide-alkyne cycloaddition and Friedel-Crafts reactions as well as hydrosilylation of alkynes

Organic reactions using metal-organic frameworks (MOFs) as catalysts are promising with regard to their environmentally friendly features and potential catalyst recyclability. A robust Co(ii)-MOF {[Co-2(l-mac)(4,4-bpt)(H2O)]center dot 3.5H(2)O}(n) (1) and its enantiomer {[Co-2(d-mac)(4,4-bpt)(H2O)]center dot 3.5H(2)O}(n) (2) (l/d-mac = basic forms of l/d-malic acid, 4,4-Hbpt = 3,5-di(pyridin-4-yl)-4H-1,2,4-triazole) have been gram-scale prepared under solvothermal conditions. Structural analysis reveals that mac manages Co(ii) ions to form 1-D chains, which are further extended via 4,4-bpt connectors into a noninterpenetrating 3D framework architecture. It was found that 1 can be as a heterogeneous catalyst for multiple organic reactions, such as azide-alkyne cycloaddition and Friedel-Crafts reactions with good isolated yields and good recycle runs (at least five times without substantial degradation). Additionally, 1 can promote hydrosilylation of alkynes under harsh conditions with moderate yield.
