An overview of factors influencing the properties of alkali-activated binders

Alkali activated binders (AABs) are evolving as alternative to Portland cement. They are predominantly synthesized using aluminosilicate materials, such as fly ash, silica fume, metakaolin, etc. However, the synthesis of these binders is very sensitive to several factors. These include the source, constituents and fineness of the precursor materials, type and combination of alkaline activators, quantity of free-water, and type and duration of curing. Though the synthesis and properties of AABs were studied in the past, there is an apprehension towards using this technology by the construction industry due to practical difficulties. These include insufficient information and understanding of the mix design, lack of uniformity in the composition of precursor materials and its possible impact on the properties of these binders. In addition, there is lack of data on the long-term performance of AABs under aggressive exposure conditions, particularly chloride-bearing environment. The findings of research studies conducted so far indicate that the mechanical characteristics of AABs are either equivalent to or better than those of Portland cement concrete. However, some aspects related to the long-term durability of these binders are yet to be fully understood, including fire-resistance. Accordingly, this paper is aimed to present an overview of parameters that affect the properties of AABs and to elaborate the polymerization mechanisms of commonly used precursor materials. Moreover, the performance of AABs exposed to aggressive environmental conditions are presented. In the light of available literature, the review indicates that future research in this area has to be focused on the development of standard specifications and evaluation procedures for the precursor materials and combinations of alkaline activators for a particular source material. In addition, it is realized that the long-term study on the durability aspects of these binders, particularly exposed to chloride-bearing environment requires considerable attention.

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.

One-Step Activation of Anode Materials from Spent Lithium-Ion Batteries as High-Performance Electrodes for Capacitive Deionization

Mesophase microporous carbon spheres (MMCS), are the anode materials of spent lithium-ion batteries (LIB), existing in large amounts on the earth that result in resource wastes and ecological pollution. In order to utilize the above waste resources, a new idea of recycling scrapped LIB anode materials was exploited to apply for capacitive deionization (CDI). Herein, the activated microporous carbon spheres (AMCS) were synthesized by a one-step KOH activation of mesophase microporous carbon spheres (MMCS). By controlling the weight ratios of KOH to MMCS, the fabricated AMCS with the optimal specific surface area of 2626 m(2) g(-1) and the pore volume of 0.98 cm(3) g(-1) were fabricated. The AMCS3-1 with a weight ratio of KOH to MMCS of 3 : 1 exhibits higher specific capacitance (196.9 F g(-1)) and lower charge transfer resistance. Importantly, the AMCS3-1 electrode demonstrates excellent electrosorption capacity of 12.73 mg g(-1) and fast salt adsorption rate of 2.64 mg g(-1) min(-1) at 1.2 V. In addition, the excellent repeatability over 50 regeneration cycles could be obtained for AMCS3-1 electrode compared with commercial activated carbon electrode. The results reveal that the AMCS3-1 is a promising candidate as high-performance electrodes for CDI. The strategy of recycling MMCS from waste LIB anode materials for CDI is desirable, which displays great potential in the removal of sodium chloride (NaCl).

A laccase Gl-LAC-4 purified from white -rot fungus Ganoderma lucidum had a strong ability to degrade and detoxify the alkylphenol pollutants 4-n-octylphenol and 2-phenylphenol

In this study, the ability of laccase Gl-LAC-4, purified from Ganoderma lucidum, to degrade and detoxify two representative alkylphenol pollutants, 4-n-octylphenol and 2-phenylphenol, was systematically studied. Gl-LAC4 laccase had a very strong ability to degrade high concentrations of 4-n-octylphenol, 2-phenylphenol, and alkylphenol mixtures. The degradation speed of Gl-LAC-4 toward 2-phenylphenol was very fast. Gl-LAC-4 displayed strong tolerance for a variety of metal salts and organic solvents in the degradation of alkylphenols. GlLAC-4 showed strong tolerance for high concentrations of various metal salts, such as MgSO4, MnSO4, Na2SO4, CuSO4, ZnSO4, CdSO4, and K2SO4, in the degradation of 4-n-octylphenol and 2-phenylphenol.In the case of the same metal cation, the inhibitory effect of the metal salt with Cl as the anion on the degradation of 4-n-octylphenol and 2-phenylphenol by laccase was stronger than that of the metal salt with SO42 as the anion. An increase in the number of chloride ions caused a greater inhibitory effect on alkylphenol degradation by laccase. Gl-LAC-4 exhibited strong tolerance for glycerol, ethylene glycol, butanediol, propylene glycol, and organic solvent mixtures in the degradation of alkylphenols. Gl-LAC-4 treatment significantly reduced or eliminated the phytotoxicity of 4-n-octylphenol and 2-phenylphenol.

Bioaccumulation of trace elements affects chick body condition and gut microbiome in greater flamingos

Elevated concentrations of trace elements represent a major concern to wetland ecosystems, since river estuaries are geochemical endpoints that accumulate pollution. Although the negative impact of environmental exposure of highly toxic elements such as Pb and Hg has received substantial attention, we still lack a comprehensive understanding of the effects that these and other common trace elements have on natural populations. We used greater flamingos as a study system within three sites that represent a gradient of pollution. Controlling for environmental sediment exposure, we assessed if signatures of bioaccumulation in feathers for ten trace elements (As, Cd, Cr, Cu, Hg, Ni, Pb, Se, Sn and Zn) are associated with two known proxies of health: body condition and the gut bacterialmicrobiome. We found evidence of an adverse effect of Se, Hg, and Pb bioaccumulation on body condition. Furthermore, bioaccumulation of the elements As, Cu, Se, Pb and Zn influenced different aspects of the gut microbiome. Bioaccumulation of Se led to a shift in the microbiome composition, largely driven by an enrichment of Bacteroides plebeius, which is linked to the breakdown of sulphated polysaccharides of algae. Bacteroides plebeius was negatively associated with chick body condition, suggesting an adverse effect of a microalgae diet rich in Se. Pb bioaccumulation was linked with a decrease in microbial diversity (adjusted-R-2 = 10.4%) and an increase in heterogeneity of the microbial community (adjusted-R-2 = 10.5%), an indication of impaired gut homeostasis. As, Cu and Zn had more nuanced effects on gut microbiome heterogeneity according to breeding site and bioaccumulation concentration. Our results therefore suggest that in addition to well-studied elements, bioaccumulation of poorly studied elements also adversely affect health of natural populations. (C) 2020 Elsevier B.V.

Determination of the critical micelle concentration and thermodynamic parameters of phenylcarbamic acid derivatives using a fluorescence method

Critical micelle concentration (CMC) values of 1-[3-(2-alkoxyphenylcarbamoyloxy)-2-hydroxypropyl]-4-(4-fluorophenyl)piperazin-1-ium-chlorides (alkoxy = methoxy to propoxy; 6a-c) were determined by a fluorescence method using pyrene as a probe over a temperature interval T = 293.15-313.15 K. The dependence of CMC on T turned out forming the U-shape. The curve was drawn by fitting of observed values using a second-degree polynomial function and so-called power-law equation, minimum of the curve was observed at T = 298.15 K. Thermodynamic parameters of micellization, i.e., molar Gibbs energy (Delta G degrees), enthalpy (Delta H degrees), and entropy (Delta S degrees), respectively, were calculated according to a phase separation model. Following the observations, the enthalpy (Delta H degrees) and entropy contributions (-T Delta S degrees) to the molar Gibbs energy (Delta G degrees) were calculated. It was found that contribution of enthalpy increased with the increase in temperature, and entropy contribution decreased within chosen range of the temperature. Finally, the enthalpy-entropy compensation and the compensation temperature (T-c) were determined.

New ternary deep eutectic solvents for effective wheat straw deconstruction into its high-value utilization under near-neutral conditions

In order to extract lignin, a novel near-neutral deep eutectic solvent (DES) was developed to treat wheat straw which facilitated its subsequent enzymatic glycation. The DES, whose in situ complexation promotes lignin depolymerization, was composed of choline chloride (ChCl), boric acid (BA), and polyethylene glycol-200 (PEG-200). Our results showed that this kind of DES could dissolve a large amount of lignin and hemicellulose yet retained cellulose well. Under optimum conditions (DES ratio of 1 : 1 : 1.5, 120 degrees C, 4 h), the proportions of lignin and hemicellulose removed amounted to 88.39% and 84.38%, respectively, with enzymatic digestibility reaching 59.3% in the subsequent enzymatic saccharification with a limited timeframe (5 days) and low enzyme load (30 FPU g(-1)). The results also demonstrated that lignin’s removal rate was positively correlated with the amount of BA used in the DES. The 2D-HSQC NMR, FTIR and TG analyses showed the regenerated lignin to be a typical H-G-S type retaining its intact structure (e.g., beta-O-4, beta-beta, beta-5, etc.), whose carbon chain backbone is stable. GPC analysis revealed that this extracted lignin had low molecular weight and a narrower distribution range. Density functional theory showed that BA could bond with -OH similar to Cl-, and it occupied more effective sites than Cl- to break the hydrogen-bonding network between lignin and cellulose. Importantly, the DES can be used multiple times without significantly reducing its efficiency, and its structure and properties remain virtually unchanged throughout the use cycle.
