High-stability, zirconium-based metal-organic frameworks are attractive as heterogeneous catalysts and as model supports for uniform arrays of subsequently constructed heterogeneous catalysts-for example, MOF-node-grafted metal-oxy and metal-sulfur clusters. For hexa-Zr(IV)-MOFs characterized by nodes that are less than 12-connected, sites not used for linkers are ideally occupied by reactive and displaceable OH/H2O pairs. The desired pairs are ideal for grafting the aforementioned catalytic clusters, while aqua-ligand lability renders them effective for exposing highly Lewis-acidic Zr(IV) sites (catalytic sites) to candidate reactants. New single-crystal X-ray studies of an eight-connected Zr-MOF, NU-1000, reveal that conventional activation fully removes modulator ligands, but replaces them with three node-blocking formate ligands (from solvent decomposition) and only one OH/H2O pair, not four-a largely overlooked complication that now appears to be general for Zr-MOFs. Here we describe an alternative activation protocol that effectively removes modulators, avoids formate, and installs the full complement of terminal OH/H2O pairs. It does so via an unusual isolatable intermediate featuring eight aqua ligands and four non-ligated chlorides-again as supported by single-crystal X-ray data. We find that complete replacement of node-blocking modulators/formate with the originally envisioned OH/OH2 pairs has striking consequences; here we touch upon just three. First, elimination of unrecognized formate renders aqua ligands much more thermally labile, enabling open Zr(IV) sites to be obtained at lower temperature. Second, in the absence of formate, which otherwise links and locks pairs of node Zr(IV) ions, reversible removal of aqua ligands engenders reversible contraction of MOF meso- and micropores, as evidenced by X-ray diffraction. Third, formate replacement with OH/OH2 pairs renders NU-1000 ca.10X more active for catalytic hydrolytic degradation of a representative simulant of G- type chemical warfare agents.

Herein we analyze the profitability of a novel regenerative process to synergize biogas upgrading and carbon dioxide utilization. Our proposal is a promising alternative which allows to obtain calcium carbonate as added value product while going beyond traditional biogas upgrading methods with high thermal energy consumption. Recently we have demonstrated the experimental viability of this route. In this work, both the scale-up and the profitability of the process are presented. Furthermore, we analyze three representative scenarios to undertake a techno-economic study of the proposed circular economy process. The scale-up results demonstrate the technical viability of our proposal. The precipitation efficiency and the product quality are still remarkable with the increase of the reactor size. The techno-economic analysis reveals that the implementation of this circular economy strategy is unprofitable without subsidies. Nonetheless, the results are somehow encouraging as the subsides needed to reach profitability are lower than in other biogas upgrading and carbon dioxide utilization proposals. Indeed, for the best-case scenario, a feed-in tariff incentive of 4.3 (sic)/MWh makes the approach profitable. A sensitivity study through tornado analysis is also presented, revealing the importance of reducing bipolar membrane electrodialysis energy consumption. Overall our study envisages the big challenge that the EU faces during the forthcoming years. The evolution towards bio-based and circular economies requires the availability of economic resources and progress on engineering technologies. (C) 2020 Elsevier B.V. All rights reserved.

Now introduce a scientific discovery about this category.

A series of Mn-Ti composite oxides (MnyTi1-yOx) were prepared via the sol-gel method, and their reducibility and surface acidity were controlled by adjusting the Mn/Ti molar ratio. In addition, as a model reaction, the catalytic activity of Mn-Ti composite oxides for the deep oxidation of vinyl chloride (VC) was evaluated. It was found that the catalyst surface acidity played a decisive role in the oxidation of VC, on the condition that the catalyst reducibility was superior to that of Mn0.4Ti0.6Ox. Consequently, a linear relationship between the surface acidity of the MnyTi1-yOx catalysts (y >= 0.4) and the reaction rate of the VC oxidation process was observed. Moreover, the influence of Lewis acidic sites originating from Ti species on the catalytic activity of the MnyTi1-yOx catalysts was revealed. These results could lead to an efficient strategy for enhancing the CVOC oxidation reaction through finely tuning reducibility and surface acidity of the catalyst.

The novel poly(vinyldiphenylphosphine) could be easily prepared by using the reactions of the cheap poly(vinyl chloride) with sodium phosphides. Poly(vinyldiphenylphosphine) is soluble in common solvents while its corresponding phosphine oxide is hardly soluble in the solvents. Taking advantage of this different solubility, poly(vinyldiphenylphosphine) could be used as a soluble phosphinopolymer for the Wittig reactions. The reactions could take place efficiently to produce the corresponding olefins while the isolation of the products were simple since the resulted poly(vinyldiphenylphosphine oxide) was not soluble in the solvent and could be easily removed by filtration.

Green nanotechnology has recently had a significant influence on advances in biological applications. The surface manipulation of iron oxide NPs by zinc oxide is increasing attention for biomedical research. Therefore, this work focused on the phytochemicals of creeper Blepharis maderaspantensis (BM) water extract for synthesizing iron oxide NPs and iron oxide/zinc oxide nanocomposite. The UV spectrum analysis showed a wavelength redshift from 294 to 302 nm of iron oxide/ZnO nanocomposite, and the polydispersity index revealed that the perfect preparations of iron oxide NPs were prepared by boiling 0.25 g of the plant in deionized water then the filtrate added to ferric chloride (1:1 v/v). The HRTEM results also illustrated that amorphous iron oxide NPs are spherical and irregular in shape. However, the iron oxide/ZnO nanocomposite showed a rod shape of ZnO with an average length and width of similar to 19.25 +/- 3.2 x 3.3 +/- 0.6 nm surrounding amorphous iron oxide NPs. Furthermore, a high antimicrobial activity with MRSA and E. coli was demonstrated by iron oxide NPs. However, because of instability and negative surface charge of the iron oxide nanocomposite, there was no antimicrobial activity. Future cytotoxic studies of the iron oxide NPs synthesized with polyphenols of BM extract are desirable, and their applications in medical purposes will be recommended.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature. 707-36-8, Name is 1-Chloro-3,5-dimethyladamantane, SMILES is CC1(C2)CC3(C)CC2(Cl)CC(C3)C1, in an article , author is Omura, Taro, once mentioned of 707-36-8, Application In Synthesis of 1-Chloro-3,5-dimethyladamantane.

Amino-functionalized cellulose particles with a porous structure were prepared by a solvent-releasing method with 1-butyl-3-methylimdazolium chloride ([Bmim]Cl) followed by an amination reaction, and were incorporated with silica. The amino groups provided the base catalyst for the formation of silica on the porous structure during the in situ sol-gel reaction of tetraethyl orthosilicate. After the reaction, no free silica remained in the reaction medium. The microscopic morphologies (specific surface area, pore diameter, and pore volume) of the composite particles were affected by the silica content in the composites, which was controllable by the sol-gel reaction time. When silver nanoparticles were introduced to the pores of the cellulose particles by reduction of AgNO3 with amino groups, the composite exhibited catalytic ability and recyclability.

Liquid-phase treatment of waste Poly Vinyl Chloride (PVC) was performed. Chlorine change rate was high when using alcohol, cresol and terpene compared with that observed in the treatment without solvent, so the importance of solvent for dechlorination from PVC was confirmed. By the treatment in alcohol, generation of porous structure was confirmed, which were not observed in the treatment of PVC alone. We were able to propose a method of utilizing carbon resources after chlorine is removed from a different perspective than previous reports. The number of pores and pore size were controlled by adding CO2 gas and basic compound, especially Na2CO3 in 1-Butanol. It indicated that these elements were effective for the production of porous structure based on the liquid-phase treatment. On the other hand, solubilization rate reached near 90% by using terpene at 300 degrees C in air atmosphere. The most effective solvent for solubilization was o-Cresol and solubilization rate reached to 99.8% at 250 degrees C in air atmosphere. This result indicates that PVC can be completely decomposed by these solvents in the presence of oxygen. From this research, it is possible to utilize and decompose solid residue by selecting the conditions.

In this paper we report new density and viscosity data of L-serine and L-valine in aqueous NaCl solutions as a function of amino acids molality at fixed salt concentration (0.1, 0.2, 0.5, 0.7 and 1.0 mol.kg(-1)) and temperature T = (293.15, 298.15, 303.15, 308.15, 313.15, 318.15 and 323.15) K at atmospheric pressure of p = 0.1 MPa. From density, some derived properties such as the apparent molar volume, V-phi, limiting partial molar volume, V-phi(0), and expansibility, E-phi(0), standard molar volume of transfer, Delta V-phi(0), and hydration number, n(H), were calculated and discussed in terms of solute-solvent interactions and structural effects. The Jones-Dole equation and transition state treatment were used to obtain the viscosity B coefficient, free energy of activation of viscous flow per mole of solvent, Delta mu(0#)(1), and per mole of solute, Delta mu(0#)(2), entropies, Delta S-2(0#) and enthalpies, Delta H-2(0#), of activation of viscous flow for amino acids. All the activation parameters were discussed in terms of transition state theory. The co-sphere overlap model was used to interpret the results. The structure making/breaking ability of the amino acids in solutions was also discussed. (C) 2020 Elsevier Ltd.

One of the prominent health problems caused by Aluminium was the decrease in male fertility rates. In the study, the protective effect of Esculetin (ESC) against the reproductive toxicity induced by Aluminium chloride (AlCl3) was investigated. For this purpose, AlCl3 was administrated to Wistar Albino rats at a dose of 34 mg/kg and ESC was administrated at a dose of 50 mg/kg for 70 days. It was determined that AlCl3 treatment reduced sperm motility and concentration, increased dead/live rate and abnormal sperm rate. It decreased serum testosterone level, and co-treatment of ESC significantly regulated these values. In the AlCl3-treated group, MDA level increased and GSH level, GPx and CAT activities decreased compared with those of the control group. However, co-treatment of ESC showed an amelioratory effect on the values except for CAT activity. It was observed that the expression level of NRF-2 increased in the ESC and AlCl3 + ESC groups, and NF-kappa B increased in the AlCl3 group with the control group. It was determined that Caspase-3 expression decreased, and Bcl-2 expression increased in AlCl3 + ESC group compared to AlCl3 group. It was also determined that AlCl3-induced tissue injury was significantly prevented by ESC co-treatment.

The poor robustness and durability of superhydrophobic surfaces under various externally imposed stresses have become a challenging issue for practical applications. Here, an efficient dissolution and modification strategy is proposed for facilely fabricating superhydrophobic polyethylene (F-PE/SiO2) foam with 98.6% porosity using sodium chloride (NaCl) as a sacrificial template and superhydrophobic nano-silica particles as a surface chemical modifier. A microscale porous and interconnected 3D framework is formed when NaCl is dissolved and the nanosilica particles adsorb on the surface of interconnected pores to form nanoscale structures. The F-PE/SiO2 foam exhibits a water contact angle (CA) of 158 +/- 2 degrees and a sliding angle (SA) of 4 +/- 2 degrees. Interestingly, the F-PE/SiO2 foam could maintain its superhydmphobicity under 980 Pa pressure of water droplet impacting and 8.1 kPa pressure of water flow impacting. Besides robust dynamic superhydrophobicity, the F-PE/SiO2 foam exhibits exceptional mechanical durability against knife scratching, tape-peeling, bending-twisting, and ultrasonication in ethanol because of unique hierarchical micro-nanostructure and the stably adsorbed nano-silica particles. Impressively, the F-PE/SiO2 foam maintains superhydrophobicity upon abrasion damage until all the thickness is worn away, which are potentially advantageous in practical applications. Moreover, this F-PE/SiO2 foam also demonstrated excellence in anti-wetting, self-cleaning and anti-icing, which makes the product can effectively reduce the damage caused by surface pollution, ice formation, and other natural factors when applied to oil-water separation and insulation material of refrigerator.
