Pore characteristics of recycled aggregate concrete and its relationship with durability under complex environmental factors

The influences and mechanisms of single and coupled effect of carbonation, dry-wet cycles and freeze-thaw cycles on the durability of three types of recycled aggregate concrete were studied. The compressive strength, chloride ion migration coefficient and micro pore parameters of recycled aggregate concrete were tested. The results showed that carbonation and dry-wet cycles can improve the pore tortuosity and reduce the connectivity of pores, while freeze-thaw cycles, coupling of carbonation and freeze-thaw cycles, and coupling of carbonation, dry-wet cycles and freeze-thaw cycles can significantly reduce the pore tortuosity and deteriorate the pore structure. The key reason for durability failure of recycled aggregate concrete in a complex environment is the increase of large pore volume fraction. When more factors are coupled, the increase in the pore volume fraction is greater. Based on the pore tortuosity and large pore volume fraction, an integrated pore index was proposed, and a prediction model of compressive strength and chloride ion migration coefficient of recycled aggregate concrete under complex environmental factors was established, which provided the basis to evaluate and maintain the durability of recycled aggregate concrete.

Application of Ionic Liquids in Aluminum and Alloy Electrodeposition

Ionic liquids have been considered as the solvent media to meet the needs of sustainable and green chemistry because of the characteristics of non-volatilization, non-combustion, high thermal stability, wide electrochemical window and so on. As a variety of active metals and alloys can be electrodeposited in ionic liquids at room temperature, ionic liquids have attracted much attention. In this review, we present the application progress of ionic liquids in electrodeposition of aluminum and aluminum alloy in recent years systematically. The types of ionic liquids used in electrodeposition of aluminum and aluminum alloy are classified. The mechanism of metal electrodeposition is summarized.

Improvement of thermal energy accumulation by incorporation of carbon nanomaterial into magnesium chloride hexahydrate and magnesium nitrate hexahydrate

Magnesium chloride hexahydrate and magnesium nitrate hexahydrate were tested for their thermal energy storage in a mixture with carbon materials. The graphite, graphene and zeolite-templated carbon replicas were used as a nucleating agent to supress supercooling. The addition of any type of carbon into magnesium chloride hexahydrate did not lead to a decrease in the supercooling and a significant decrease of the enthalpy of fusion and crystallisation was observed. The mixtures after cycling were apparently wet, indicating that some of the magnesium chloride was dissolved in its structural water. In the case of magnesium nitrate hexahydrate, the addition of carbon replicas of zeolite beta, mordenite or faujasite lead to a decrease in supercooling. Nevertheless, graphite and graphene provided the highest supercooling suppression from about 30 to 2.2 K within the fifty cycles. The thermal conductivity measurement of pressed tablets of magnesium nitrate hexahydrate with carbon materials at 2 MPa showed a significant increase of 9% and 15% for the addition of 3 mass% of graphene and 3 mass% of graphite, respectively. Mixing of magnesium nitrate hexahydrate with graphene or graphite improved heat transfer and significantly reduced unwanted supercooling, which is necessary for its use in thermal energy accumulation.

Corrosion performance of hot-dip galvanized zinc-aluminum coated steel rebars in comparison to the conventional pure zinc coated rebars in concrete environment

In this investigation zinc was alloyed with aluminum in order to improve the corrosion resistance of hot-dip galvanized coated steel rebars in contact with chloride-contaminated concrete. To rapidly assess the role of aluminum alloying in zinc, test panels in sheet form containing 10%, 15%, 20%, and 30% aluminum in zinc were prepared and evaluated in terms of their corrosion resistance via salt spray exposure tests. It was found that 10%Al-90%Zn (10AZ) provided the best results. Mild steel rebars were galvanized in 90% Zn-10%Al and 100%Zn (100Z) baths and their corrosion resistance performances when they were exposed to simulated concrete pore solution and embedded in mortars were examined. The10AZ-coated rebar showed superior corrosion resistance performance to the 100Z-coated rebar. Electrochemical impedance spectroscopy, DC polarization, scanning electron microscopy, Raman spectroscopy, and X-ray diffraction techniques were used to study the kinetics and corrosion mechanism of the coated rebars.

Gamma-phase Zn-Ni alloy deposition by pulse-electroplating from a modified deep eutectic solution

This article describes the electroplating of Zn-Ni alloy from a modified deep eutectic solvent (DES), a mixture of choline chloride (ChCl) and ethylene glycol (EG) commonly known by its commercial name Ethaline. In this study the Ethaline was modified with propylene carbonate (PC) to decrease the solution viscosity. Boric acid was also used as an additive to improve surface finish and adhesion. The modifications were shown to increase the reduction rate of metal ions through improved mass transport and also to improve the quality of finish (morphology and interfacial adhesion) of the coating. We demonstrate that it is possible to produce dense, thick and adherent coatings of a y-phase Zn-Ni alloy with 81-85% Zn on mild steel substrates using either potentiostatic deposition or controlled current pulse-plating techniques. Mild steel is a typical substrate for a sacrificial anti-corrosion coating used in many applications where the alloy serves to protect the steel from corrosion in harsh environments.

Ammonium sulfate production from wastewater and low-grade sulfuric acid using bipolar- and cation-exchange membranes

Conventional electrodialysis can be used to recover ammonia from dewatering centrate (i.e., downstream wastewater from digested sludge dewatering). However, ionic impurities of the recovered ammonia solution are still a limiting factor for broad applications of ion-exchange membranes (IEMs) in wastewater treatment and resource recovery. In this study, an electrodialysis stack with bipolar membranes (BPMs) and cation exchange membranes (CEMs) but without anion exchange membranes (AEMs) was examined under various operation conditions to demonstrate high-purity ammonium sulfate production using low-grade sulfuric acid and dewatering centrate. Two significant benefits of removing AEMs from the bipolar membrane electrodialysis (BMED) are no more membrane fouling problems on AEMs and complete exclusion of impurity anions (e.g., chloride ions) in the recovered ammonium sulfate solution. A higher applied voltage condition (30 V over 7 pairs of CEM and BPM) resulted in a substantially high ammonia recovery (88.4%) and concentration (4.34 g-N/L) in 90 min. The ammonia recovery and concentration were also improved by increasing the flow rate through the BMED stack. The lowest electric energy consumption in the membrane stack was 9.6 kW h/kg-N, indicating energy efficient production of high-purity ammonium sulfate from wastewater. The amount of divalent cation scales accumulated in the BMED stack was linearly proportional to the average electric current, implying that the scaling problem can be controlled by reducing the applied voltage. Even with the scale accumulation, the electric current generation (i.e., separation performance) was hardly affected during the experiment. These findings demonstrated the strong potential of AEM-lacking BMED for practical ammonia separation from wastewater with reduced impurities. (C) 2020 Elsevier Ltd. All rights reserved.

Mercury exposure induces the release of neutrophil extracellular traps and apoptosis in carp neutrophils

Mercury, an important toxic contaminant, has been reported to have toxic effects on fish and mammals. Neutrophil extracellular traps (NETs) not only plays an important role in defending against infection but also leads to the damage of the tissues. In this study, we aimed to investigate the effects of mercury exposure on the formation of NETs in carp neutrophils. Neutrophils were isolated from the blood of common carps and incubated with different concentrations of mercury chloride. The formation of NETs were observed by laser confocal microscopy and quantitatively measured by picoGreen. The results showed that mercury chloride significantly induced the formation of NETs in carp neutmphils, which was a DNA-based network structure modified with myeloperoxidase (MPO) and histone (H3). Meanwhile, treatment of mercury chloride increased the production of reactive oxygen species (ROS), and decreased the activities of SOD and CAT. Furthermore, mercury treatment could induce the apoptosis of carp neutrophils. In addition, the results showed that mercury chloride-induced NETs were not inhibited by NADPH oxidase inhibitor DPI, AMPK inhibitor Compound C and p38 inhibitor 58202190, suggesting it was independent of ROS, AMPK, and p38. In conclusion, the results indicated that mercury chloride could induce the formation of NETs, which plays an important foundation for further study on the influence and mechanism of mercury chloride on the immune system.

The Impact Of Foliar Salicylic Acid In Salt-Exposed Guava (Psidium Guajava L.) Seedlings

The rising demand for guava fruit worldwide is due to its richness in vitamin C, high yielding and two bearing seasons. Given the salt stress threat to guavas and the necessity of protective strategies, in the present research guava seedlings were subjected to sodium chloride (0 and 50 mM) and salicylic acid (0 and 1 mM). To ascertain a logical conclusion, the activity of antioxidant enzymes, antioxidant capacity of DPPH, ferric reducing antioxidant power, total flavonoid and phenol contents were monitored in salt-exposed guava seedlings. Based on our findings, the most superoxide dismutase (87.46 mu mol min(-1)g(-1)DW) activity, ferric reducing antioxidant power (408.82 mmol g(-1) DW), DPPH scavenging activity (80.65%), flavonoid (14.15 mg QE(-1) g DW) and phenol (34.02 mg GAE g(-1) DW) contents were found in 50 mM NaCl-exposed plants, which were enriched by 1 mM salicylic acid. A high correlation was observed among non-enzymatic antioxidant parameters (DPPH scavenging activity, ferric reducing antioxidant power, total flavonoid content and total phenol content). In conclusion, salicylic acid improved guavas salt tolerance by increasing both enzymatic (peroxidase and superoxide dismutase) and non-enzymatic (ferric reducing antioxidant power, DPPH scavenging activity, total phenol and flavonoid contents) pathways.

Catalytic Activity of Pt Loaded Zeolites for Hydroisomerization of n-Hexane Using Supercritical CO2

The present study investigates the synthesis of novel strontium (Sr) and barium (Ba) modified crystalline zeolites including Zeolite Socony Mobil-5 (ZSM-5) and Mordenite (MOR) utilizing a batchwise ion-exchange method with an appropriate chloride solution of 3 N at pH 7.2 and 50 degrees C. Modified zeolites (Ba-ZSM-5 and Ba-MOR, Sr-ZSM-5 and Sr-MOR) were coated with an inert metal (Pt) by a novel supercritical CO2 method using PtMe2COD as a precursor for n-hexane hydroisomerization in a microreactor unit at different temperatures (250-325 degrees C), H-2/HC ratios of 3, 6, and 9, and a pressure of 5 bar. The acidic and physical features of Pt loaded zeolites were systematically characterized using FT-IR, XRD, BET surface area measurements, TGA, and TEM techniques. It is found that the metal loading in scCO(2) results in more uniform and very small metal nanopartide (1.37 nm) dispersion with high stability after reduction. It is also revealed that high loading pressure in scCO(2) (280-300 bar) results in higher catalytic activity and surface area. The maximum conversion and selectivity of about 80 and 90% were achieved for n-hexane isomerization at 275 degrees C and a H-2/HC ratio of 6 for Pt/Sr-ZSM-5 catalyst. Results reported that Pt loaded over all zeolites (H-MOR, Sr-MOR, Ba-MOR, H-ZSM-5, Ba-ZSM-5, and Sr-ZSM-5) by the scCO(2) method showed the minimum production of cracking products (C-1-C-5) and maximum isomeric products including iso-C-6 isomers (2,2-DMB, 2,3-DMB, 2-MP, and 3-MP). Furthermore, the overall results of the rate of reaction revealed that Pt/Sr-ZSM-5 and Pt/Ba-ZSM-5 catalysts showed a better rate of isomerization (46.44%) and conversion (47%) for n-hexane at 300 degrees C and a H-2/HC ratio of 9 with a minimum rate of cracking. However, it is conduded that the small, pored size Pt loaded ZSM-5 zeolite showed the highest catalytical activity compared to large pored MOR zeolite making it of great interest for diesel and gasoline formation in the oil refining industry.

Synthesis of tetragonal BaTiO3 nano-particle via a novel tartaric acid co-precipitation process

A novel tartaric acid co-precipitation process was firstly reported to prepare tetragonal BaTiO3 nano-powder with barium chloride, titanium tetrachloride as raw materials and tartaric acid as precipitant agent. The as-obtained BaTiO3 powder exhibited a small average particle size about 140 nm, which still held a high tetragonality (c/a ratio) of 1.0092, suggesting its promising applications in multilayer ceramic capacitors (MLCC). In addition, this synthetic method will be of general interest to people who focuses on synthesis technology of Ti-based multicomponent oxides nano-materials owing to its outstanding advantages, including mild reaction condition, facile synthetic processes and especially stabilization of (TiO)(2+) even in a high pH about 8.
