Kinetic study of microwave enhanced mercury desorption for the regeneration of spent activated carbon supported mercuric chloride catalysts

A novel microwave enhanced mercury desorption process was proposed for the regeneration of the spent activated carbon supported mercuric chloride catalysts. The mercury species desorption kinetics were investigated in detail by TG experiments, the overall apparent activation energy of 128.4 kJ/mol, the main reaction activation energy of 95.84 kJ/mol and the adsorption energy of 32.56 kJ/mol were confirmed with the combination of the model-free method and the DMol(3) DFT module of Materials Studio package. The thermal desorption of HgCl2 and Hg2Cl2 were mainly between 473 K and 670 K, and the dominant mechanism for the desorption process was determined as second-order-model by the model-fitting method and the Z(alpha) master-plot method. Furthermore, the microwave enhancement degree of 26.36% was proved by the microwave heating experiment for the mercury desorption within 1500 s at 673 K, and the mercury content was significantly reduced from 19500 mg/kg to 149 mg/kg, which met the requirement of US land disposal restrictions (<260 mg/kg). Moreover, the preliminary activation of the spent activated carbon after microwave heating was demonstrated from the results of XRD, SEM and nitrogen adsorption analysis. Meanwhile, the HgCl2 solution with the concentration of 40-50 g/L could be effectively prepared by the water leaching of the condensate of mercury species, which could be used to regenerate the catalyst by soaking adsorption with activated carbon after microwave heating. Finally, a novel microwave enhanced mercury desorption process was proposed, which can synchronous realize the harmless and recovery of the spent activated carbon supported mercuric chloride catalysts.

Locomotor deficits induced by lumbar muscle inflammation involve spinal microglia and are independent of KCC2 expression in a mouse model of complete spinal transection

Spinal cord injury (SCI) is associated with damage to musculoskeletal tissues of the spine. Recent findings show that pain and inflammatory processes caused by musculoskeletal injury mediate plastic changes in the spinal cord. These changes could impede the adaptive plastic changes responsible for functional recovery. The underlying mechanism remains unclear, but may involve the microglia-BDNF-KCC2 pathway, which is implicated in sensitization of dorsal horn neurons in neuropathic pain and in the regulation of spinal excitability by step-training. In the present study, we examined the effects of step-training and lumbar muscle inflammation induced by complete Freund’s adjuvant (CFA) on treadmill locomotion in a mouse model of complete spinal transection. The impact on locomotor recovery of each of these interventions alone or in combination were examined in addition to changes in microglia and KCC2 expression in the dorsal and ventral horns of the sublesional spinal cord. Results show that angular motion at the hip, knee and ankle joint during locomotion were decreased by CFA injection and improved by step-training. Moreover, CFA injection enhanced the expression of the microglial marker Ibal in both ventral and dorsal horns, with or without step-training. However, this change was not associated with a modulation of KCC2 expression, suggesting that locomotor deficits induced by inflammation are independent of KCC2 expression in the sublesional spinal cord. These results indicate that musculoskeletal injury hinders locomotor recovery after SCI and that microglia is involved in this effect.

Broadband dielectric spectroscopy for monitoring temperature-dependent chloride ion motion in BiOCl plates

The dielectric properties and electrical conduction mechanism of bismuth oxychloride (BiOCl) plates synthesized using chloramine-T as the chloride ion source were investigated. Thermally-activated structure rebuilding was monitored using broadband dielectric spectroscopy, which showed that the onset temperature of this process was 283 K. This rebuilding was related to the introduction of free chloride ions into [Bi2O2](2+) layers and their growth, which increased the intensity of the (101) diffraction peak. The electrical conductivity and dielectric permittivity were related to the movement of chloride ions between plates (in the low-frequency region), the interplanar motion of Cl- ions at higher frequencies, vibrations of these ions, and charge carrier hopping at frequencies above 10 kHz. The influence of the free chloride ion concentration on the electrical conductivity was also described. Structure rebuilding was associated with a lower concentration of free chloride ions, which significantly decreased the conductivity. According to the analysis, the BiOCl plate conductivity was related to the movement of Cl- ions, not electrons.

The effect of natural and artificial periphytic substrates with biofloc system on shrimp Penaeus vannamei (Boone 1931) culture: growth and immune response

A 120-day experiment was conducted to understand the growth and immunomodulatory response of Penaeus vannamei reared in biofloc-integrated periphyton system-like natural substrates like bamboo (NS1), sugarcane bagasse (NS2), artificial substrates like polyvinyl chloride mat (AS1), agricultural shed net (AS2), and a control group without biofloc and substrate. Experiments were carried out in 500-L fiber-reinforced plastic (FRP) tanks at a stocking density of 100 nos/m(3) (0.256 g). Shrimps reared in natural substrate-based treatments, (NS1 and NS2) recorded highest average body weight (ABW) and survival followed by artificial ones (AS1 and AS2), and were significantly higher (P < 0.01) compared with control. Significantly higher chlorophyll(a), ash-free dry matter (AFDM), and THB load were recorded in NS (1 and 2) followed by AS (1 and 2). Contrastingly, the Vibrio load was higher in control than treatments. Relative percentage survival was higher (P < 0.01) in treatments when challenged against V. parahaemolyticus. Serum protein level, phenoloxidase activity, and superoxide dismutase assay were significantly higher in natural and artificial substrate groups when compared to control. Immunomodulatory effects through immune gene study revealed a two fold to four fold upregulation in cytMn-SOD and mtMn-SOD genes in NS groups. Similarly, the lysozyme and prophenoloxidase genes were significantly upregulated in the treatment groups. The results conclude that biofloc with natural followed by artificial periphytic substrates were observed to deliver better performances, protective response, and immunomodulatory effects in pacific white shrimp P. vannamei culture.

Phase Transition from the Interdigitated to Bilayer Membrane of a Cationic Surfactant Induced by Addition of Hydrophobic Molecules

Although the transition between a bilayer and an interdigitated membrane of a surfactant and lipid has been widely known for long, its mechanism remains unclear. This study reveals the transition mechanism of a cationic surfactant, dioctadecyldimethylammonium chloride (DODAC), through experiments and theoretical calculations. Experimentally, the transition from the interdigitated to bilayer structure in the gel phase of DODAC is found to be induced by adding hydrophobic molecules such as n-alkane and its derivatives. Further addition induces a different transition to another bilayer phase. Our theory, considering the competition of the electrostatic interaction between cationic headgroups and the hydrophobic interaction emerging at the alkyl-chain ends exposed to water, reproduces these two phase transitions. In addition, changes in alkyl-chain packing in the membranes at these transitions are reproduced. The underlying mechanism is that the interdigitated membrane is formed at a small additive content due to electrostatic repulsion. As the energetic disadvantage with respect to the hydrophobic interaction becomes dominant as the content increases, the transition to the bilayer occurs at a specific content. The bilayer-bilayer transition at a higher content is induced by the change in the balance of these interactions. Based on a similar concept, we suggest the mechanism of the additive-induced bilayer-interdigitated transition of phospholipids, i.e., neutrally charged (zwitterionic) surfactants.

Analysis of microstructure and texture of gluten- and lactose-free cereal bars, produced with different hydrocolloids and drying temperatures and no-added sugar

A gluten- and lactose-free cereal bar with no-added sugar, suitable for lactose intolerants and for celiac people was developed. The cereal bar was formulated with extruded rice, oat flakes, flaxseeds, sesame, sunflower lecithin, hydrocolloids, maltodextrin, mannitol, maltitol syrup, and sodium chloride. The effect of three different hydrocolloids (locust bean gum, pectin, and carboxymethyl cellulose), and processing temperature on microstructure, moisture content, A(w), texture, and sensory properties of cereal bars was assessed by an L9 orthogonal experimental design based on Taguchi methods. Results indicated that A(w) and moisture content were not affected by the type or levels of the hydrocolloids studied, but decreased with the increase in drying temperature. Hardness and fracturability values increased with temperature increase. From the Scanning Electron Microscopy analysis, it was concluded that increasing processing temperature provides a more uniform microstructure of cereal bars. The application of the Taguchi method, allowed identifying the temperature as being the factor of greater influence on the characteristics of the cereal bars. In addition, according to this method, the optimum formulation is 0.05% locust bean gum and 0.1% pectin with 70 degrees C as the optimum processing temperature. Practical applications Organizations responsible for public health throughout the world are increasingly concerned with the feeding of populations, and great efforts are made to promote the adoption of nutritious and balanced diet in order to decrease the occurrence of the chronic diseases constantly related to inadequate diets. Cereal bars were introduced over a decade ago as a healthy alternative confectionery, and became a convenience food, as they can be easily consumed, do not require any preparation and are a source of essential nutrients, such as vitamins, minerals, fibers, proteins, and complex carbohydrates. The effect of the combination of different levels (0%, 0.05%, and 0.1% wt/wt) of locust bean gum, pectin, and carboxymethyl cellulose, and three drying temperatures (20 degrees C, 60 degrees C and 70 degrees C), on microstructure, sensory, and texture properties of the cereal bars was analyzed. Results obtained with this work showed that it is possible to produce a gluten- and lactose-free cereal bar with no-added sugar, suitable for lactose intolerants and for celiac people. This can be achieved by taking advantage of the synergy between two hydrocolloids in different concentrations to improve the hardness of the cereal bar. Also, with the help of an experimental design based on Taguchi method it was possible to find out the optimum formulation and processing temperature of the cereal bars. In this work, the results show that the temperature also has a great influence, with 70 degrees C being the most suitable to promote greater hardness.

Novel solvent-resistant nanofiltration membranes using MPD co-crosslinked polyimide for efficient desalination

Solvent-resistant nanofiltration (NF) membranes have numerous application prospects. In this study, a novel solvent-resistant nanofiltration membrane with a double layered polyamide structure was prepared for efficient desalination. The substrate was polyimide crosslinked with m-phenylenediamine (MPD), and the surface layer was polyamide prepared by typical interfacial polymerization. The crosslinking was confirmed by Fourier transform infrared spectroscopy. Investigation of the effects of different reaction conditions on membrane performance showed that the optimal reaction conditions were found to be: 5% aqueous MPD solution with crosslinking time of 10 min and piperazine concentration of 0.1% (m/v). The rejection rate for sodium sulfate and sodium chloride were 99.13% and 97.45%, respectively. The membrane morphologies were studied by scanning electron microscopy and atomic force microscopy. The membrane showed electronegativity in the pH range of 3.0-10.0 and its contact angle was 54.28 degrees, indicating excellent hydrophilicity. After soaking in several solvents for a week, the membrane still had a high rejection rate of more than 90% for Na2SO4, demonstrating its excellent solvent resistance.

Investigation of the surface properties of dibutyl amine modified poly(styrene) based polymer by inverse gas chromatography method

In the present study, poly(vinyl benzyl chloride) (PVBC) was prepared by the radical polymerization method. Then, PVBC was reacted with dibutyl amine to obtain tertiary amine-modified poly(styrene) based polymer (PVBC-Dibutyl amine) and the resulting polymer was characterized. Surface properties of the polymer were investigated by inverse gas chromatography method at infinite dilution region. For this purpose, the retention diagrams of carefully selected polar and non-polar solvents (probes) on PVBC-Dibutyl amine were obtained over a temperature range from 30 to 50 degrees C. By using the diagrams, the dispersive component of the surface free energy of the polymer surface was calculated for the studied temperatures by two different methods. The specific enthalpy of adsorption and the specific component of the adsorption free energy of solvents on PVBC-Dibutyl amine which are adsorption thermodynamic parameters were determined for each solvent used. Using the adsorption data, Lewis acid and Lewis base parameters of PVBC-Dibutyl amine surface were calculated. The obtained parameters reflected that surface of PVBC-Dibutyl amine exhibited a basic behavior. Considering the values in the literature, the effect of dibutyl amine moieties in the structure of poly(styrene) based polymer PVBC-Dibutyl amine on the dispersive surface free energy and acid-base parameters of poly(styrene) was discussed.

Electrocatalytic Oxidation of Methanol by a Polymeric Ni Complex-Modified Electrode Prepared by a One-Step Cold-Plasma Process

In this work, a polymeric nickel complex-modified indium tin oxide (ITO) electrode was prepared by a one-step cold-plasma process of acrylic-Ni complex precursors. Also, the work provides the electrocatalytic oxidation of methanol by a polymeric Ni complex-modified electrode prepared by a simple one-step cold-plasma process. The acrylic-Ni complex precursors were synthesized by complexation of nickel (II) chloride, and acrylic acid in a small amount of water; subsequently we added N,N ‘-methylene-bis-acrylamide as a crosslinking agent to the complex solution. We characterized the prepared polymeric Ni complex-modified (Ni-modified) catalytic electrode by X-ray photoelectron spectroscopy, field emission scanning electron microscopy, and electrochemical methods. Electrochemical characterization showed stable redox behavior of Ni(III)/Ni(II) couples. Cyclic voltammetric experiments have shown that electrocatalytic oxidation of methanol can occur on Ni-modified catalytic electrodes, while not observed on bare ITO. As a result, this work provides the simple and easy preparation of electrocatalysts by one-step plasma process for methanol fuel cell.

Chloride ions migration and induced reinforcement corrosion in concrete with cracks: A comparative study of current acceleration and natural marine exposure

The aim of this paper is to investigate the corrosion relationship between reinforced concrete exposed to natural marine environment and applied current acceleration. Chloride ions migration and reinforcement corrosion behaviour in different cracked concrete are studied by two testing methods: 700-day exposure in a marine tidal zone and applied current accelerated corrosion. The mechanism comparison of chloride ion diffusion between two techniques is discussed. The results show that cracks have more influence on reinforced concrete under electrochemical corrosion than that under natural exposure. The corrosion rates of natural and accelerated corrosion were quantitatively compared: the latter is two orders of magnitude faster than the former when the crack width is over 0.20 mm. The different composition and distribution of corrosion products between techniques are demonstrated. (C) 2020 Elsevier Ltd. All rights reserved.
