Performance based energy, ecological and financial costs of a sustainable alternative cement

This paper presents a comparison of the energy and ecological impacts and financial costs of Alkali Pozzolan Cement (APC), High Volume Fly Ash (HVFA) cement and Ordinary Portland Cement (OPC) mixtures. The embodied energy, carbon dioxide emission and financial costs were calculated per unit weight of dry binder powder; per unit volume per unit strength of hydrated hardened binder; and finally per unit volume per unit strength per year of service. The performance based indicators therefore consider both strength and durability; with the latter based both on carbonation and chloride environments. The statistical means and variability of the costs were also computed. The results indicate that the energy, ecological and financial costs of APC are very attractive compared to those of OPC or HVFA, when considered either as the cost per unit weight of binder or as the cost per unit performance, whether related to unit strength or both unit strength and year of service. The variability of the APC cost indicators was also the lowest in general among the cements considered. However, OPC is still arguably the best when only carbonation exposure is involved during service. (C) 2020 Elsevier Ltd. All rights reserved.

Mechanical and durability properties of recycled aggregate concrete produced from recycled and natural aggregate blended based on the Densified Mixture Design Algorithm method

The aim of this study was to reuse recycled concrete aggregates for concrete production by using the Densified Mixture Design Algorithm (DMDA) method for blended aggregates and mixing design based on the evaluation of characteristics of recycled aggregate concrete (RAC). Recycled coarse aggregate (RCA) was used to replace 30%, 40%, and 50% of the natural coarse aggregate (NCA), respectively, by volume in the samples, and the fine aggregate was a combination of 70% natural fine aggregate (NFA) and 30% recycled fine aggregate (RFA) by volume. A series of tests, including compressive strength, splitting tensile strength, ultrasonic pulse velocity (UPV), electrical surface resistivity (ESR), thermal conductivity (TC), water absorption, and the rapid chloride penetration test (RCPT) were conducted in accordance with the relevant standards. The results illustrated that blending aggregates following to DMDA method suggested an optimum proportion of RCA level which exhibited with highest volume of aggregate per unit volume of combination of RCA and NCA. The results revealed 40% RCA content as the optimum replacement level. Furthermore, the 40% RCA concrete mix exhibited good hardening properties in terms of being only slightly below the 30% RCA mix and significantly higher than the 50% RCA mix. All of the RAC mixtures designed by DMDA method with low cement consumption exhibited good strength development and good durability through 120 days of curing.

Enhanced removal of aqueous phenol with polyimide ultrafiltration membranes embedded with deep eutectic solvent-coated nanosilica

Novel composite hydrophilic ultrafiltration (UF) membranes, comprising a polyimide (PI) matrix embedded with silica-based nanofillers are established for the enhanced vacuum-filtration removal of small polar organics such as phenol from water. Spherical silica nanoparticles are first prepared by the surfactant-templated sol-gel approach, then coated with choline chloride-ethylene glycol deep eutectic solvent (DES) by post-impregnation. The modified silica nanofillers are introduced into the PI matrix through the casting solution, which is then used to develop the composite UF membranes by phase inversion. The spectroscopy and high-resolution electron microscopy measurements evidence the presence of DES on the surface of the modified silica nanofillers. The topographical atomic force microscopy studies, dynamic water contact angle, and zeta potential measurements conducted on the native polymer membrane and those embedded with bare-silica and DES-coated silica confirm the successful incorporation of nanofillers into the PI matrix. An optimum nanofiller loading of 2 wt% is found to preserve the membrane structure and give the best mechanical properties as well as for the UF performance characteristics in vacuum-filtration studies at 85 kPa. Consistently, the DES-silica modified PI UF membranes (DES@SiO2@PI) exhibit exceptional water permeate flux (300 L m(2) h(-1)) and removal efficiency (96%) for 30 mg L-1 aqueous phenol compared with the native polymer and SiO2-modified membranes. The DES-engineered composite membranes can be operated within a wide feed pH window (pH: 2-10) without displaying significant loss in their removal efficiency. The pH and zeta potential results suggest that the interaction of phenol with the optimized membranes is governed by cooperative adsorption/Lewis acid-base mechanisms via hydrogen bonding and assistive ion-exchange interactions with the ethaline coating.

Activation of peroxymonosulfate by calcined electroplating sludge for ofloxacin degradation

Developing cost-effective metal/metal oxides for peroxymonosulfate (PMS) activation remains a key issue in the sulfate radical based advanced oxidation process. In this work, electroplating sludge (ES), a transition metal-rich byproduct, was anaerobic calcined and characterized. Then, calcined electroplating sludge (CES) was applied as PMS activator for degradation of ofloxacin (OFL) and CES/PMS system exhibited a nearly 90% of OFL removal in 60 min. In addition, effect of CES, PMS, the initial pH and water constituents (chloride, bicarbonate, natural organic matter (NOM) and water backgrounds) on OFL degradation were systematically studied. Moreover, radical quenching tests and electron spin-resonance spectroscopy studies manifested that both SO4 center dot- and HO center dot were the ruling reactive oxygen species. X-ray photoelectron spectroscopy results of the fresh and used CES demonstrated that the PMS activation mainly occur in the transformation from Fe3+ (Cu2+) to Fe2+ (Cu+). Furthermore, liquid chromatography coupled with ion trap time-of-flight mass spectrometry was used to illustrate the possible degradation pathway of OFL. Moreover, CES showed excellent stability and reusability during reaction. This work points out a new way for value-added reuse for ES as a cost-efficient activator of PMS for organic contaminant removal. (C) 2020 Elsevier Ltd. All rights reserved.

Cyclic Peptidyl Inhibitors against CAL/CFTR Interaction for Treatment of Cystic Fibrosis

Cystic fibrosis (CF) is caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene, encoding for a chloride ion channel. Membrane expression of CFTR is negatively regulated by CFTR-associated ligand (CAL). We previously showed that inhibition of the CFTR/CAL interaction with a cell-permeable peptide improves the function of rescued F508del-CFTR. In this study, optimization of the peptidyl inhibitor yielded PGD97, which exhibits a K-D value of 6 nM for the CAL PDZ domain, >= 130-fold selectivity over closely related PDZ domains, and a serum t(1/2) of >24 h. In patient-derived F508del homozygous cells, PGD97 (100 nM) increased short-circuit currents by similar to 3-fold and further potentiated the therapeutic effects of small-molecule correctors (e.g., VX-661) by similar to 2-fold (with an EC50 of similar to 10 nM). Our results suggest that PGD97 may be used as a novel treatment for CF, either as a single agent or in combination with small-molecule correctors/potentiators.

On the ligand exchange, redox, and disproportionation processes of tetrachloroaurate in the presence of a pyridine derivative

The potential applications of Au-I precursors and pyridine derivatives for shape-directed nanoparticle growth has provided an impetus for the present study of the chemistry of tetrachloroaurate (AuCl4-) in the presence of 4-methoxypyridine (Py-/). Electrochemical experiments show that the addition of Py-/ to AuCl4-leads to the co-existence of both Au-III and Au-I species as evidenced by the observation of two reduction events in the cyclic voltammetry. Kinetic analyses have been used to show that multiple ligand exchange processes occur over the course of several minutes and result in the formation of a Au-III species with two Py-/ and a variable number of chloro and hydroxo ligands in the inner sphere. The kinetics of the initial Py-/ substitution reaction are shown to follow a modified form of the two-term rate law typical of square planar complexes. The observation of a slow, but spontaneous, conversion of Au-III species to Au-I species has been explained by estimating the standard reduction potential for the pyridine/pyridine-N-oxide redox couple and demonstrating that it can drive a galvanic reaction with the AuPy/Cl-2(q)(OH)(2-q)(+)/AuPy2/+ redox couple. The previously reported tendency of this system to form highly anisotropic gold nanoparticles on conductive metal oxide electrodes is explained by a thermodynamic analysis of the disproportionation reaction of AuPy2/+ (C) 2020 Elsevier Ltd.

Chemically Durable Poly(phenylene-co-arylene ether) Multiblock Copolymer-Based Anion Exchange Membranes with Different Hydrophobic Moieties for Application in Fuel Cells

Quaternized multiblock poly(phenylene-co-arylene ether)s (QPPs) are synthesized from a pre-aminated monomer and a series of chlorine-terminated oligo(arylene-ethers) via a nickel coupling reaction. Their properties are investigated as anion exchange membranes with the goal of obtaining membranes with enhanced performance and durability for alkaline membrane fuel cell applications. Three different oligo(arylene ethers) were synthesized and introduced in the hydrophobic block of the polymer backbone to study its effect on the membrane properties. The chloride ion conductivity of the QPP membranes was significantly less dependent on the humidity compared to that of the commercial Fumatech membrane due to the well-defined hydrophilic-hydrophobic phase separation, as confirmed by TEM. An accelerated alkaline stability test indicated that the QPPs were more stable than the commercial Fumatech membrane up to 1700 h. The QPP-6F membrane shows an alkaline membrane fuel cell single-cell performance with a maximum power density of 534 mW cm(-2) at 70 degrees C.

Nanoencapsulation of food bioactives in supramolecular assemblies based on cyclodextrins and surfactant

The bioavailability of poorly soluble food ingredients can be achieved by their encapsulation into the 3D macrocyclic structure or self-assembled surfactant micelles. In this study, the mixed self-assembly of cyclodextrins (CDs) and cationic surfactant, 1-hexadecyl-4-(2-(1-methylpyridin-1-ium-4-yl)vinyl)pyridin-1-ium chloride, was studied by a set of physicochemical methods. It was shown using tensiometry and conductometry that the presence of CDs in the micellar medium of this surfactant increases the critical aggregation concentration. Moreover, NMR spectroscopy and spectrophotometry revealed the interaction between the alkyl tail of surfactant and the internal cavity of CDs. It is interesting to note that in the case of gamma-CD and HP-beta-CD there was additional binding by the vinyl group of surfactant. The observed patterns of aggregation behavior were confirmed by the method of solubilization of hydrophobic substances. Spectrophotometric monitoring of the solubilization of hydrophobic flavonoids (rutin and quercetin) demonstrated that mixed assemblies enriched with surfactant are capable of binding the flavonoid, while they show poor binding ability towards flavonol compound in the presence of a small amount of surfactant.. Variation of the component ratio in the supramolecular CD-surfactant system also allows adjusting the biological properties. Systems with an excess of CD are less toxic to the cells of test microorganisms, herewith, an increase of the surfactant content in a mixture with CD leads to an increase in both antimicrobial and hemolytic activities. Therefore, when using CD complex-based supramolecular approach for food safety, it is necessary to take into account the toxic properties of the base components of the supramolecular mixture.

Catalytically active nanosized Pd9Te4 (telluropalladinite) and PdTe (kotulskite) alloys: first precursor-architecture controlled synthesis using palladium complexes of organotellurium compounds as single source precursors

Several intermetallic binary phases of Pd-Te including Pd3Te2, PdTe, PdTe2, Pd9Te4, Pd3Te, Pd2Te, Pd20Te7, Pd8Te3, Pd7Te2, Pd7Te3, Pd4Te and Pd17Te4 are known, and negligible work (except few studies on PdTe) has been done on exploring applications of such phases and their fabrication at nanoscale. Hence, Pd(ii) complexes Pd(L1)Cl-2 and Pd(L2-H)Cl (L1): Ph-Te-CH2-CH2-NH2 and L2: HO-2-C6H4-CH = N-CH2CH2-Te-Ph were synthesized. Under similar thermolytic conditions, complex Pd(L1)Cl-2 with bidentate coordination mode of ligand provided nanostructures of Pd9Te4 (telluropalladinite) whereas Pd(L2-H)Cl with tridentate coordination mode of ligand yielded PdTe (kotulskite). Bimetallic alloy nanostructures possess high catalytic potential for Suzuki coupling of aryl chlorides, and reduction of 4-nitrophenol. They are also recyclable upto six reaction cycles in Suzuki coupling.
