Energetics of chloride adlayers on Au(100) electrodes: Grand-canonical Monte Carlo simulations and ab-intio thermodynamics

Based on extensive DFT calculations for 84 different geometrical configurations of adlayers, we have investigated the adsorption of chlorine atoms on the unreconstructed Au(100) surface for different coverages. We have confirmed the stability of several structures observed in experiments. In particular, the stability of defective c(2 x 2) arrangements showing patches separated by domain boundaries has been established. We have developed a strategy to use DFT parameters in grand canonical Monte Carlo simulations. Both the simulations and ab-initio thermodynamics show structural changes with the electrochemical potential consistent with experiments. (C) 2020 Elsevier Ltd. All rights reserved.

Direct Synthesis of Methyl Chlorosilanes from Pd-Mg-SiO2 Substrates Using Mechanochemistry

The direct reaction of methyl chloride with magnesium and palladium infused silica substrates to synthesize methyl chlorosilanes is reported. First, high energy ball milling on solid Mg-SiO2 mixtures produces elemental silicon and MgO. When PdCl2 is infused into the mixture, after additional ball milling and high-temperature reduction under H-2, dipalladium silicide (Pd2Si) is produced. The silicon of the Pd2Si readily reacts with MeCl under Muller-Rochow reaction conditions, to produce methyl chlorosilanes at yield ratios analogous to those of the traditional process. The dominant product is Me2SiCl2 (selectivity > 30%), followed by MeSiCl3 and Me3SiCl, with minor amounts of the remaining chlorosilanes. Silicon conversion exceeds 20% for most of the substrates. The elemental palladium, which remains within the Pd-Mg-SiO2 contact mass is re-converted to Pd2Si at the next H-2/high-temperature treatment and reacts again with MeCl to repeat the methyl chlorosilane production. In principle, the resulting cycle of the mechanochemically induced formation of Pd2Si followed by the reaction with MeCl can be repeated until the starting SiO2 converts completely to methyl chlorosilanes.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 870-24-6. Formula: C2H7Cl2N.

Self-healing of early-age cracks in cement mortars with artificial functional aggregates

Cracking seriously affects the functionality and durability of the concrete structure. Therefore, the development of robust self-healing concrete is important to extend the service life of the structure. In this study, artificial functional aggregates with fly ash, silica fume, metakaolin, limestone powder and sodium carbonate powder were designed and prepared by the powder granulation technology to promote the self-healing efficiency of concrete. Mortar specimens with artificial functional aggregates which partially replaced the sand were prepared to verify the feasibility of the approach. Crack self-healing efficiency was evaluated by visual observation and the water ingress test. In addition, healing products formed in the crack were analyzed with XRD, TG and SEM, respectively. Experimental results indicated that the artificial functional aggregates were well combined with the mortar matrix and could be intersected by cracking. The addition of artificial functional aggregates improved the self-healing capacity of mortar specimens. Mortar specimens with artificial functional aggregates exhibited higher closure ratio of surface crack and better regain of water tightness compared with the control specimens. The maximum crack width that can be healed was about 0.47 mm in the mortar specimen with artificial functional aggregates. Microstructure investigation showed that the major healing products in the crack mouth were calcite precipitations which firstly deposited on both walls of the crack and then gradually overlapped together to become denser and denser with the extension of healing time. More calcium carbonate precipitations were observed in internal crack of mortars with artificial functional aggregates compared to the control mortar due to the effective supply of carbonate ions from the artificial functional aggregates. Typical hydration product C-S-H gel was also detected by SEM observation in the internal crack wall. (C) 2020 Elsevier Ltd. All rights reserved.

Time-variant probabilistic assessment of corrosion initiation of marine concrete structures considering maximum phenomenon

This study presents a new dual time-variant chloride diffusion model considering maximum phenomenon for concrete structures exposed to marine environment. The model is developed from the assumption that the concentration gradient is the sole or dominant driving force for chloride ingress in concrete, and both the chloride diffusion coefficient and peak chloride content are considered as time-variant. The applicability and accuracy of the developed model are verified by comparing the fitted and predicted chloride profiles with field data. Based on the developed model, time-variant probabilistic evaluation of corrosion initiation in a typical prestressed box girder located near coast is carried out. Results reveal that the maximum phenomenon has a significant effect on the prediction of the time to corrosion initiation. The results of sensitivity analysis indicate that the critical chloride content is the decisive parameter in the prediction of the corrosion initiation time, followed by the relative humidity, water-to-binder ratio, temperature, thickness of concrete cover, etc. Besides, the effects of the correlation between random variables and the distance from the coast on the time-variant probability of corrosion initiation are investigated. It is found that the correlation among random variables should be considered, and the effect of distance from the coast on the time-variant probability of corrosion initiation is sharply decreasing at a very short distance from the coast.

Electromagnetic wave absorption performance of magnesium phosphate cement functionalized by nano-Fe3O4 magnetic fluid and hollow glass microspheres

In light of high bonding and early strengths, magnesium phosphate cement (MPC) functionalized with nano-Fe3O4 magnetic fluid and hollow glass microspheres (HGM) that exhibited excellent electromagnetic wave absorption performance (EWAP) was fabricated in this study. Coating a construction surface with multifunctional MPC could effectively withstand electromagnetic radiation hazards. Effects of the Fe3O4-like ferrite content and type (i.e., nano-Fe3O4 magnetic fluid, nano-Fe3O4 particles and magnetite), and the surface roughness of specimens on the EWAP of the MPC were investigated by lab tests. Test results showed that the Fe3O4-like ferrite greatly improved the EWAP of the MPC and the enhancement effectiveness was in descending order of nano-Fe3O4 magnetic fluid > nano-Fe3O4 particles > magnetite. Among the samples tested in this study, MPC blended with 5 wt% nano-Fe3O4 magnetic fluid showed an optimal EWAP as indicated by a peak reflection loss of -11.2 dB and bandwidth of 9.67 GHz below -10 dB. Additionally, the reflection loss of the MPC in the high frequency range could be further improved by carving notches on the surface to increase the number of microwave reflections. The electromagnetic energy absorbing mechanism and the hydration progress of the MPC were further analyzed with SEM/EDS and XRD results. The hydration degree of the MPC got improved due to the lubricating effect of HGM and filling effect of nano-Fe3O4 magnetic fluid, which also optimized its micro structure and compressive and flexural strengths. From this study, the nano-Fe3O4 magnetic fluid and HGM modified MPC had potential application in the construction of buildings for enhanced resistance to electromagnetic radiation.

Eco-innovative possibilities for improving the quality of thawed cod fillets using high-power ultrasound

In order to improve the quality of thawed cod fillets and minimize the impact of processing, an extended hydration phase is applied in the fishery product industry in order to recover the water lost during freezing and thawing. Such long phases not only compromise productivity, but increase the chances of microbial growth in fish. Ultrasound (US) is a technology that could reduce these long hydration times, thanks to its capacity to improve mass-transfer processes, thereby limiting the development of fish microbiota. This investigation studies the effect of different US intensities (25 kHz, 29.4 W/kg to 2.9 W/kg, 113.7 to 15.3 W) on weight gain (WG) in the hydration process of cod fillets. The influence of the hydration medium’s pH (from pH 8.5 to 10.5) in combination with US was likewise evaluated. Microbiological and sensory analyses were carried out at the end of the hydration process in order to evaluate its impact. The higher the applied US power, the lower was the WG. US intensities of 2.9 W/kg produced the highest increments in WG (18.6%), reducing hydration time by 33% and thereby achieving the same hydration values as in control samples. The combination of US with a controlled pH of 8.5 permitted to shorten hydration time by an additional day, and also led to improved microbial quality in comparison with control samples. Sensorial analyses indicated that after 5 d of hydration, Quality Index Method (QIM) values were better than those obtained for control samples after 5 and 7 d. Specifically, color and gaping were the sensorial attributes of cod fillets better protected with the application of US.

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.

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.

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.

Inhibitory effects of functionalized polycarboxylate retarder on aberrant thickening phenomena of oil well cement at high temperature

Aberrant thickening of cement slurry caused by polycarboxylate retarders mainly refers to abnormal gelation and thickening time reversal (TTR) when temperature reaches above 120 degrees C. These phenomena would directly jeopardize cementing operation and hinder the application of polycarboxylate retarders in oil and gas exploitation. Herein, two functionalized polycarboxylate retarders were synthesized to overcome the challenges in complex conditions. The incorporation of isoprenyl oxy poly(ethyleneglycol) ether (TPEG) and [3-(methacryloylamino) propyl] trimethyl ammonium chloride (MAPTAC) was capable of preventing unfavorable crosslinking and chelation reaction between cement grains and polymer, thereby avoiding abnormal gelation. It was also found that the hydrophobic association behavior of long side chain in TPEG could cause the gradual release of carboxyl groups at elevated temperature, which was unfavorable for TTR inhibition. When the TPEG was replaced by N-Vinyl-2-Pyrrolidinone (NVP), its retarding effect gradually weakened when temperature rose from 130 degrees C to 150 degrees C, and excellent inhibition of TTR was achieved.
