Knowledge of speciation and thermodynamic properties for aqueous gold complexes are important for both the understanding and numerical modelling of the formation of hydrothermal gold deposits. While gold speciation in chlorine- and sulfur-rich hydrothermal fluids has been investigated by considerable theoretical and experimental studies, the complexation of gold with other ligands that may be important for transporting gold in hydrothermal fluids, such as hydroxyl (OH-) and ammonia (NH3) complexes, have received limited attention so far. In this study, we conduct ab initio molecular dynamics (MD) simulations to calculate the coordination structures of Au(I)-OH and Au(I)-NH3 complexes. Our simulations show linear structures of Au(I) complexes with two bonded ligands (OH-/NH3/H2O), consistent with previous experimental and theoretical studies of Au(I) complexation (e.g., Liu et al., 2014). The new speciation models show that Au(I)-OH-/NH3/H2O complexes are stable in hydrothermal fluids and vapors. We also use thermodynamic integration to determine the formation constants of these species at temperatures up to 350 degrees C and at water-saturated pressures; furthermore, we extrapolate these properties to wider temperatures and pressures range based on the Modified Ryzhenko-Bryzgalin equation of state parameters. In particular, this study, for the first time, reports the speciation and formation constants of mix-ligand [Au(NH3)(OH)]((aq))(0) complexes. The derived formation constants show that the stability of Au(I)-NH3 complexes decreases progressively with increasing temperature. The quantitative modelling of gold solubility based on the new thermodynamic data shows that gold can be transported as Au(I)-OH-/NH3 complexes in sulfur-poor and ammonia-rich hydrothermal fluids. In sulfur-bearing ore fluids, ammonia is only likely to transport small amounts of gold as [Au(NH3(OH)]((aq))(0)in hydrothermal fluids in the near-neutral to alkaline fluids under extremely reduced conditions.

Steel bars in concrete structures can become severely corroded in chloride salt-containing environments, which can shorten the service life of the structure. Bidirectional electromigration rehabilitation (BIEM), a novel type of durability repair technology used on reinforced-concrete (RC) structures experiencing chlo-ride corrosion, involves applying an electric field to discharge chloride ions from concrete and simultaneously applying a rust inhibitor to the steel surface. In this study, indoor experiments were performed to analyse the migration of chloride ions and the corrosion inhibitor in RC structures in the atmosphere and water-level-fluctuating areas. An electroosmotic device enhanced the efficiency of BIEM. The BIEM was particularly effective in wet-dry areas and inside the electroosmotic device. More than 90% of the chloride ions on the steel surface were removed within 15 mm of the electroosmotic device, and the chloride ion migration rate on the steel surface was 40%-60%. Scanning electron microscopy revealed that the surface of the steel bars was smooth after BIEM treatment, with no obvious pitting or corrosion products. The service life of concrete was calculated according to the prediction method of concrete. It can be expected that the concrete enters the early warning zone after 15 years and the rust zone after 30 years. (C) 2020 Elsevier Ltd. All rights reserved.

Antibody-drug conjugates (ADCs) constitute an emerging class of anticancer agents that deliver potent payloads selectively to tumors while avoiding systemic toxicity associated with conventional chemotherapeutics. Critical to ADC development is a serum-stable linker designed to decompose inside targeted cells thereby releasing the toxic payload. A protease-cleavable linker comprising a valine-citrulline (Val-Cit) motif has been successfully incorporated into three FDA-approved ADCs and is found in numerous preclinical candidates. Herein, we present a high-yielding and facile synthetic strategy for a Val-Cit linker that avoids extensive protecting group manipulation and laborious chromatography associated with previous syntheses and provides yields that are up to 10-fold higher than by standard methods. This method is easily scalable and takes advantage of cost-effective coupling reagents and high loading 2-chlorotrityl chloride (2-CTC) resin. Modularity allows for introduction of various conjugation handles in final stages of the synthesis. Facile access to such analogues serves to expand the repertoire of available enzymatically cleavable linkers for ADC generation. This methodology empowers a robust and facile library generation and future exploration into linker analogues containing unnatural amino acids as a selectivity tuning tool.

The safety assessment of cosmetic products is based on the safety of the ingredients, which requires information on chemical structures, toxicological profiles, and exposure data. Approximately 6% of the population is sensitized to cosmetic ingredients, especially preservatives and fragrances. In this context, the aim of this study was to perform a hazard assessment and risk characterization of benzalkonium chloride (BAC), benzyl alcohol (BA), caprylyl glycol (CG), ethylhexylglycerin (EG), chlorphenesin (CP), dehydroacetic acid (DHA), sodium dehydroacetate (SDH), iodopropynyl butylcarbamate (IPBC), methylchloroisothiazolinone and methylisothiazolinone (MCI/MIT), methylisothiazolinone (MIT), phenoxyethanol (PE), potassium sorbate (PS), and sodium benzoate (SB). Considering the integrated approaches to testing and assessment (IATA) and weight of evidence (WoE) as a decision tree, based on published safety reports. The hazard assessment was composed of a toxicological matrix correlating the toxicity level, defined as low (L), moderate (M), or high (H) and local or systemic exposure, considering the endpoints of skin sensitization, skin irritation, eye irritation, phototoxicity, acute oral toxicity, carcinogenicity, mutagenicity/genotoxicity, and endocrine activity. In a risk assessment approach, most preservatives had a margin of safety (MoS) above 100, except for DHA, SDH, and EG, considering the worst-case scenario (100% dermal absorption). However, isolated data do not set up a safety assessment. It is necessary to carry out a rational risk characterization considering hazard and exposure assessment to estimate the level of risk of an adverse health outcome, based on the concentration in a product, frequency of use, type of product, route of exposure, body surface location, and target population.

Most of the iminopyridyl Ni (II) and Pd (II) catalysts are reported to oligomerize ethylene or yield very low molecular weight polyethylene. Moreover, the molecular weight of product is not sensitive to ligand sterics. In this contribution, we demonstrate that the bulky rotation-restricted substituents incorporated into iminopyridyl Ni (II) and Pd (II) catalysts that provide the right orientation are highly effective in retarding the chain transfer. Thus, (2,6-bis(10,11-dihydro-5H-dibenzo[a,d][7]annulen-5-yl)-4-methylphenyl)-1-(pyridin-2-yl)methanimine nickel (II) bromide (Ni3) and (2,6-bis(10,11-dihydro-5H-dibenzo[a,d][7]annulen-5-yl)-4-methylphenyl)-1-(pyridin-2-yl)methanimine palladium (II) methyl chloride (Pd3) with the phenyl substituents fixed in the diarylmethyl moiety produce polyethylene or functionalized polyethylene (ethylene-MA copolymer) with high M-n values up to 2.5 x 10(4) g mol(-1), while allowing the high MA incorporation (3.2%-13.8%). In addition, the effects on the (co)polymerization behavior as a function of rotation-restricted substituent variations (free rotation, restricted rotation and fixation) were systemically studied. As a result, various molecular weight polyethylene and ethylene-MA copolymer with high MA incorporation ratio were also obtained in this system.

Synthesis of a novel lignin-based epoxy resin curing agent and study of cure kinetics, thermal, and mechanical properties

In this contribution, first of all, the methoxy groups of organic solvent lignin (OSL) was converted to phenolic hydroxyl groups through demethylation reaction for the purpose of fabricating demethylated organic solvent lignin (DOSL). In addition, the resulting DOSL was utilized as a renewable material to synthesize a novel esterified lignin (EDOSL) by reacting with isobutyryl chloride for curing of epoxy resin. Finally, commercial liquid diglycidyl ether of bisphenol A was cured by EDOSL in the presence of 4-dimethylaminopyridine (DMAP) used as a catalyst based on dual-curing mechanism. Dual curing is a processing methodology based upon the alliance of two diverse and compatible polymerization reactions occurring sequentially or simultaneously. According to the FTIR spectra and H-1-NMR analyses, the demethylation of OSL, esterification of DOSL, and the curing reaction of epoxy resin with EDOSL were successfully conducted. The value of the phenolic hydrogen in the DOSL was approximately 4.89 mmol/g, which increased by 12.64% after demethylation. The thermal and mechanical performances of these cured epoxy samples were measured by DSC, DMA, TGA, and tensile testing. The epoxy system cured by 10%wt esterified lignin with 1%wt DMAP possessed the tensile strength of 71.54 +/- 7.50 MPa and the initial degradation temperature (T-5%) of 370 degrees C, which can compete fairly with commercial aromatic curing agents or other lignin-based agents studied currently for the curing of epoxy systems.

Molecular simulation of osmometry in aqueous solutions of the BMIMCl ionic liquid: a potential route to force field parameterization of liquid mixtures

Despite widespread development and use of ionic liquids (ILs) in both academic and industrial research, computational force fields (FFs) for most of those are not available for a precise description of inter-species interactions in aqueous environments. In the scope of this study, by means of molecular simulations, the osmotic coefficient of an aqueous solution of an IL is calculated and used as a basis to reparameterize popular IL-FFs existing in the literature. We first calculate the osmotic coefficients (at 298.15 K and 1 atm pressure) of aqueous solutions of 1-butyl-3-methylimidazolium chloride (BMIMCl), a generic IL, popularly used in biomass processing and the subsequent conversion to value-added intermediates. The performance of two popular atomic, nonpolarizable FFs developed for BMIMCl, one by Lopes, Padua, and coworkers (FF-LP) and the other by Sambasivarao, Acevedo, and coworkers (FF-SA), when mixed with the SPC/E water model, is tested with respect to their ability to reproduce the experimental osmotic coefficient data. Interestingly, the osmotic coefficient is found to be increasing with a gradual increase in IL molality within the concentration range of our investigation, which is contrary to the experimental trend reported in the literature for the same IL-water mixture. Henceforth, necessary corrections to the nonbonded ion-ion and ion-water interactions are made to match the experimental osmotic coefficient. To further assess the reliability of the new FF, we extensively explore the thermodynamic (density, isothermal compressibility, and thermal expansion coefficient), dynamic (diffusivity and viscosity), and association/dissociation properties (rationalized with the help of radial distribution functions) with both the original and reparameterized FF for a wider range of concentrations up to a molality of 18.50 mol kg(-1). The calculated quantities are compared against experimental data wherever available. The modified FF parameters exhibit significant improvements in terms of its ability to match experimental solution properties, such as density, viscosity, association/dissociation, etc. We report that excessive dissociation of BMIMCl in water is responsible for the shortcomings observed in the original FFs and improved prediction of physicochemical properties could be achieved using the modified FFs.

Retention of anions in cobalt hydroxide with Ni substitution to emphasize the role of anions and cations for high current density in oxygen evolution reactions

Herein, we report the fabrication of remarkably fine nickel-substituted alpha-Co(OH)(2) sheets using an ingenious co-precipitation method at a lower pH value. An alpha-CoNiOOH sheet retains the parent alpha-Co(OH)(2) structure consisting of both tetrahedral (Td) and octahedral (Oh) sites with the retention of interlayer chloride ions, which is in contrast to the previous reports. The as-synthesized alpha-CoNiOOH sheet exhibits excellent oxygen evolution reactions (OERs) and produces a current of 10 mA cm(-2) at an overpotential of merely 190 mV in an alkaline environment. Moreover, the alpha-CoNiOOH sheet attains an exceptionally high current density of 100 mA cm(-2) at a low overpotential of only 270 mV. Additionally, this electrocatalyst possesses a 33 mV dec(-1) Tafel slope with higher values of TOF (11 s(-1)) and double-layer capacitance (7.76 mF cm(-2)). This enhancement is attributed partially to the substitution of Ni during the conversion of alpha-Co(OH)(2) to alpha-CoNiOOH and partially to the exceptionally thin sheets allowing potential octahedral sites for improved oxygen evolution reactions.

Chloride Diffusion and Induced Reinforcement Corrosion in Concrete with Fly Ash and Ground-Granulated Blast-Furnace Slag Exposed to Marine Submerged Zone(1)

This paper investigates the influence of mineral admixtures fly ash (FA) and ground-granulated blast-furnace slag (GGBS), the byproducts of industry, on chloride ions migration and corrosion resistance performance. A novel preparation method of wire beam electrode (WEB) was also introduced to explore the excellent corrosion-resistant capacity of concrete with mineral admixtures. By comparing concrete specimens with and without FA and GGBS, the test result of wire beam electrode, rapid chloride migration (RCM), and electrochemical tests highlight the positive impact of fly ash and GGBS against chloride ions migration, respectively. Concrete with fly ash and GGBS supplies an advanced protection effect of ordinary Portland cement; meanwhile, CO2 emission amount can be significantly reduced. Moreover, homemade wire beam electrode was proved to be a novel and reliable test method against corrosion, which has agreement with the test result of an electrochemical device.

Palladium extraction from chloride solutions with the disulfide of bis(2,4,4-trimethylpentyl)dithiophosphinic acid

Palladium extraction from chloride solutions with the disulfide of bis(2,4,4-trimethylpentyl)dithiophosphinic acid (L) is reported in this work. The rate of palladium extraction with the disulfide in toluene is slow but it increases in the presence of trioctylamine (TOA). Within 5 min, the degree of palladium recovery (epsilon) is 99.6%, whereas in the absence of TOA, it is only 19.0% in 10 min. The extraction systems based on the disulfide and TOA mixtures exhibit fast kinetics, high selectivity and can be used for the extraction of palladium from various industrial solutions.
