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.

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.

#REF!

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.

Biogas slurry retention is a critical problem that cannot be solved by using the reuse method. Therefore, a new approach was taken to compensate for the shortcomings in the reuse method. In this study, after ammonia stripping, the ammonia nitrogen concentration in the stripped biogas slurry (SBS) still cannot reach the effluent standard (80 mg/L), so a variety of processes were needed to treat the SBS. Poly-aluminum chloride (PAC) and rice husk biochar (B) were used to pretreat SBS. The effect of different pretreatments on the COD value, ammonia nitrogen concentration, turbidity, total phosphorus (TP), and other indicators was investigated. After different pre-treatments by PAC and biochar, the pretreated SBS was filtered by a ceramic membrane, and the indicators of SBS were removed in the next step. After adding PAC and biochar together, ammonia nitrogen concentration was decreased to 68.09 mg/L, with a removal rate of 63%. The total phosphorus (TP) was also decreased, and its removal rate reached 92.5%. When the SBS was pretreated with PAC and biochar and then filtered through a ceramic membrane under different operating pressures, the removal rates of COD, total nitrogen (TN), turbidity, and suspended solids (SS) reached 81%, 88%, 96%, and 99% respectively. Moreover, by increasing the pressure from 0.1 to 0.3 MPa, the membrane flux was improved from 45 to 100.6 L/m(2).h. This study proves that the combined pre-treatments of PAC and biochar can comprehensively remove various indicators from SBS while ensuring membrane flux during the membrane filtration process.

In this research, the separation of tellurium from selenium was studied from chloride solution by TBP extractant. In the batch experiments, the experimental findings indicated that the feed acidity, TBP concentration, and contact time were optimized to achieve the high separation factor. In continuous mode of pulsed disc and doughnut column, the impacts of operating parameters have been discussed on the distribution coefficients of selenium and tellurium, and mass transfer enhancement. A new model for predicting K(oc)a was proposed in terms of holdup values, Sherwood, Reynolds, and Schmidt numbers, which has an acceptable agreement with the mass transfer data.

Antimicrobial cationic amphiphiles have broad-spectrum activity, and microbes do not readily develop resistance to these agents, highlighting their clinical and industrial potential. Cationic amphiphiles perturb the integrity of membranes leading to cell death, and the lack of discrimination between microbial and mammalian plasma membranes is thought to be one of the main barriers of using these agents for the treatment of systemic infections. Here, we describe the synthesis and study of 20 antimicrobial cationic amphiphiles that are derivatives of the aminoglycoside nebramine with different numbers of alkyl chain ethers that differ in length and degree of unsaturation. We determined antifungal activities and evaluated hemoglobin release from red blood cells as a measure of membrane selectivity and analyzed how serum influences these activities. Microscopic images revealed morphological transformations of red blood cells from the normal double-disc shape to empty ghost cells upon treatment with the cationic amphiphiles. Antifungal activity, hemolysis, and morphological changes in red blood cells decreased as the percentage of serum in the culture medium was increased. In images of red blood cells treated with fluorescently labeled amphiphilic nebramine probes, the accumulation of the cationic amphiphiles in the membranes decreased as serum concentration increased. This suggests that, in addition to its known effect of preventing the deformability of red blood cells, serum prevents interactions between cationic amphiphiles and the plasma membrane. The results of this study indicate that biological activities of cationic amphiphiles are abrogated in serum. Thus, these agents are suitable for external and industrial uses but probably not for effective treatment of systemic infections.

Conductive, self-healing, and adhesive hydrogels are of great significance in wearable electronic devices. The most important properties of conductive self-healing hydrogels are the efficient recovery of both electrical and mechanical properties at room temperature and prolonged durability. In this work, we developed a novel double-network hydrogel consisting of poly(4-styrene sulfonate-co-methyl-uracil-imidazolium) chloride (PSS-MUI), gelatin, and ferric ions (Fe3+). Here, the MUI serves as a supramolecular crosslinker, while ferric ions act as ionic crosslinkers between gelatin and PSS functional groups. The hydrogel demonstrated excellent stretchability and outstanding ionic conductivity. The reversible nature of dynamic hydrogen bonding and ionic and metal coordination interactions rendered the hydrogel selfhealing ability, strong adhesion, and rapid electrical performance recovery. Variation in the Fe3+ concentration proved to influence the time window of hydrogel processability and allowed tuning the hydrogel mechanical and ion-conducting properties. The optimal Fe3+ ion concentration for use in a processable, ion-conducting hydrogel was found to be 2 wt %. During repeated stretching, the hydrogel showed only small changes in its electrical resistance. An electric circuit was successfully assembled onto a flexible polyurethane (PU) substrate where the power supply, light-emitting diode, and resistor were connected with the hydrogel, serving as a conductive wire. Upon breakage of the wire, simple extrusion of the hydrogel precursor into the gap yielded instant repair of the circuit. Thus, the hydrogel demonstrated suitability for use in flexible electronic devices.

Inspired of the synergistic effect of the antifouling performance of hydrophilic substance and the self-cleaning function of low surface energy material, we designed and synthesized a kind of macromolecule amphiphilic graft copolymer by the free radical polymerization, which used polyvinyl chloride (PVC) as the main chains, poly (ethylene glycol) methacrylate (PEGMA) as the hydrophilic segment and trifluoroethyl methacrylate (TFEMA) as the low surface energy segment. Then, the amphiphilic PVC-g-PPEGMA/PTFEMA graft copolymer membrane was successfully prepared via surface segregation through the phase inversion process and was further optimized via the forced self-assembly through annealing treatments. The results showed that the PPEGMA chain segments migrated on the membrane surface which driven the PTFEMA chain segments to enrich on the membrane surface during the annealing process, meanwhile, annealing treatment promoted the local microphase separation and improved the mean pore size and the porosity. Based on the synergistic effect of hydrophilic and low surface energy segments, the PVC-g-PPEGMA/PTFEMA graft copolymer membrane obtained the maximum pure water flux of 510.69 +/- 16.28 L . m(-2). h(-1), flux recovery rate of 91.49% and rejection rate of 99.31% in the BSA filtration process, which also revealed significantly antifouling properties. More importantly, the PVC-g-PPEGMA/PTFEMA copolymer membrane exhibited long-time hydrophilic stability, which could extend its potential service life.

Corrosion induced failure of buried ferrous pipelines causes significant economic losses to the world. Many of the existing buried water pipelines are made of ductile iron in most of the developed countries. Literature shows that the research on the corrosion-induced degradation assessments of ductile iron pipelines is limited and mostly deals with the physical deterioration i. e., loss of wall thickness determined by short-term research. This paper addresses this gap and presents a comparatively long-term study on the corrosion and its subsequent effect on the composition and nanomechanical properties of buried ductile iron pipelines in the accelerated corrosive environment. For experimentation, ductile iron specimens were immersed in the acidic simulated soil solution for 365 days. Physical deterioration assessment over the time was carried out in terms of corrosion rates measured at intervals of 180 and 365 days. A significant change in the percentage composition of key elements and phases were quantified. Furthermore, the mechanical properties of the grains were found to be considerably reduced after 365 days of immersion in the acidic environment by the nanoindentation technique. The results revealed an alarming increase of structural degradation at nano scale for some of the grains due to chloride induced localised corrosion. The significance of the current research is its in-depth analysis of the corrosion-induced degradation of ductile iron pipes which enhances the knowledge related to the failure of these pipelines.
