Dehalogenation of Aryl Bromides by CuO/ZrO2 in The Presence of Alcohols as Hydrogen Donors

The in-situ formed metallic Cu particles on the ZrO2 surface were prepared and applied to catalyze dehalogenation of a series of aryl bromides to produce corresponding products in 1-octanol with a yield of >99 %. The mechanistic investigation suggests that the Cu(0) nanoparticles served as hydrogen transfer active sites for degrading alcohols and adsorbing aryl bromides at the reaction system. The results showed that the catalyst was efficient with high reusability. The alcohol not only served as a reducing agent for CuO but also a safe green hydrogen donor. This methodology could be used as a powerful, low-cost, and safe technology for reducing halogenated aromatics.

The OpBench Ethereum opcode benchmark framework: Design, implementation, validation and experiments

Ethereum is a public, permissionless blockchain, with Ether as cryptocurrency, and with Turing-complete smart contracts to implement arbitrarily complex distributed applications. Correct operation of Ethereum relies on appropriately rewarding participating nodes (called miners) for the resources used to run the blockchain. In Ethereum the Used Gas determines the reward miners receive for executing a smart contract. If the Used Gas is proportional to the cost of executing a smart contract, irrespective of the platform used, then all miners are incentivized identically. In this paper we propose OpBench, a platform-independent benchmark framework for Ethereum, as a lightweight approach to determine if for operational code (opcodes) the rewarded Used Gas is proportional to the invested CPU time. We implement OpBench for PyEthApp (in Python), Go-Ethereum (in GoLang) and Parity (in Rust). From the experiments we conclude that Used Gas is not always proportional to the required CPU, with up to an order of magnitude difference between opcodes. We also conclude that for most opcodes Parity performs the best of the three clients and that preference for Linux or Windows depends on the chosen Ethereum client software. (C) 2020 Elsevier B.V.

The regulated emissions and PAH emissions of bio-based long-chain ethers in a diesel engine

Catalytic etherification is a new and developing method for the upgradation of pyrolysis bio-oil into high performance bio-based long-chain ethers. In this work, the application of bio-based long-chain ether oxygenated additives in diesel engines have been checked by focusing on their regulated emissions and PAH emissions. Four bio-based long-chain ethers with similar structures, including: Polyoxymethylene dimethyl ether, diglyme, dipropylene glycol dimethyl ether and tripropylene glycol methyl ether have been blended with diesel fuel and tested in a small-duty diesel engine. The results showed that long-chain ethers were beneficial to the reduction of regulated emissions by comparing to pure diesel. Polyoxymethylene dimethyl ether and tripropylene glycol methyl ether showed best performance among the four tested ethers. Polyoxymethylene dimethyl ether could reduce 56% CO, 23% NO and 93% soot emissions, while Tripropylene glycol methyl ether could reduce 52% CO, 28% NO and 88% soot emissions. Besides, the particle sizes of soot particles from the blended fuels were also reduced. What’s more, the addition of bio-based long-chain ethers could reduce particulate PAHs emissions by 39% similar to 67% and reduce gaseous PAHs emissions by 25% similar to 44%, and the PAHs toxicity was also reduced by 32% similar to 55%. This work proved that the structure of oxygen atoms evenly distributed in the chain could efficiently suppress the production of soot precursors and eventually reduce the soot emission

Synergistic effects of graphene nanoplatelets on X-band electromagnetic interference shielding, thermal expansion and thermal stability of poly (ether-ketone) based nanocomposites

In this work, the electromagnetic interference shielding effectiveness (EMI-SE) of the poly(ether-ketone) (PEK)-graphene nanoplatelets (GNP) nanocomposites fabricated by planetary ball mill followed by hot pressing were investigated in X-band (8.2-12.4 GHz). A percolation threshold of about 0.4 vol% GNP was obtained. The electrical conductivity was increased to about 0.02 S/cm with an EMI-SE of similar to 33 dB for 1 mm thick 5 vol% GNP filled PEK nanocomposite. This higher value is corresponding to more than 99.95% blocking of the EMI. The EMI-SE increases with increasing thickness of the nanocomposite. The thermal stability and the char yield of the nanocomposites reinforced with 5 vol% GNP were found to increase to 570 degrees C and to 61.6%, respectively. The dimensional stability of the nanocomposites was also increased compared to neat PEK.

(15-crown-5)BiI3 as a Building Block for Halogen Bonded Supramolecular Aggregates

We present the synthesis and characterization of (15-crown-5)BiI3 (1) and (15-crown-5)BiI3 center dot 0.5TIE (2), a halogen bonded adduct with tetraiodoethylene (TIE), a typical halogen bond donor. Single crystal structure analysis of 2 suggests a halogen bonding interaction between crown ether complex and TIE. The two compounds’ thermal, optical and vibrational properties are investigated in comparison, with differences pointing towards a notable interaction between the two building blocks in 2. Our results show that crown ether complexes of main group metal halides can be employed as halogen bond acceptors for the synthesis of new supramolecular aggregates.

Comprehensive exploration of the ultraviolet degradation of polychlorinated biphenyls in different media

As one of the most important natural transformation processes, photodegradation deserves more attention and research. In the current work, we comprehensively explored the photochemical behaviors of polychlorinated biphenyls (PCBs) in n-hexane (Hex), methanol/water, and silica gel under UV-irradiation. Photodegradation rates were found to be faster in methanol/water than in Hex. All of the three photochemical systems generated sigmatropic rearrangement products. The dominant photodegradation pathways were dechlorination, dechlorination/methoxylation/hydroxylation, and hydroxylation in Hex, methanol/water, and silica gel systems, respectively. Furthermore, some new photodegradation products, such as polychlorinated biphenyl ethers, polychlorinated dibenzofurans, polychlorinated biphenylenes, and methylated polychlorinated biphenyls, are reported for the first time. These findings would provide deeper insight into the phototransformation behaviors of PCBs. (C) 2020 Elsevier B.V. All rights reserved.

Flame-responsive aryl ether nitrile structure towards multiple fire hazards suppression of thermoplastic polyester

Multiple fire hazards (heat, smoke, dripping) caused by thermoplastic polymers pose integrated risks. Halogen or phosphorus flame-retardants tend to increase toxic, smoke or dripping hazards due to their flame-retardant mechanism. The physical blending flame-retardants into matrixes also presents a migration dilemma with causing potential environmental threats. Herein, we propose a novel multi-hazards inhibition strategy by chemical-incorporating aryl ether nitrile structures into poly(ethylene terephthalate)(PET), which is a typical thermoplastic polymer and a major contributor of multiple fire hazards. Through flame-responsive cyclotrimerization and aliphatic fragment capture, the flammability risks and multi-hazards (heat, smoke, toxicity, dripping) are significantly suppressed. The limiting oxygen index of the modified PET increases from 21.0 to 31.0. The peak of heat release, total smoke release, and carbon monoxide production decrease by 49.0 %, 31.1 %, and 52.6 %, respectively. The dripping hazards are eliminated, and the UL-94 rating reaches to V-0 level with no dripping production. Hence, this state-of-art strategy supplies a new approach for the fire hazards suppression of thermoplastic polymers.

Machine Learning of ignition delay times under dual-fuel engine conditions

Dual-fuel (DF) compression ignition engines, which employ a high-reactivity pilot fuel (e.g. diesel or DME) to ignite a low-reactivity lean premixed charge (e.g. methane/air), have been proposed to meet stringent pollutant regulations. Due to the complex multiscale interaction among flow, chemistry and flames, DF combustion exhibits a complicated, multi-modal combustion regimes and is hence challenging to model. Ignition delay time (IDT), as one of the most important parameters, is typically considered to develop an understanding and modeling strategy for complex ignition processes. However, accurate calculations and measurements of the IDTs over a wide range of fuel blends, pressures and flow conditions is a time-consuming, complicated procedure. While several physics-based IDT models have been proposed for single fuel ignition, they are subject to some limitations in DF scenarios. In this work, two different supervised Machine Learning methods: a glass box – High Dimensional Model Representation (HDMR) and a black box – Convolutional Neutral Network (CNN) are employed to seek an accurate and efficient prediction of the IDTs of DF. First, the underlying mechanisms of DF interaction during the ignition process are investigated. The results show that the DF ignition process is highly complex, involving negative-temperature coefficient (NTC) behavior, two-stage ignition, and multiple combustion modes and transition. Then, data needed to train HDMR and CNN is generated by a large number of transient counterflow and homogeneous reactor calculations covering DF engine conditions. The trained HDMR and CNN models are tested with numerical and experimental databases. The results show that both HDMR and CNN can capture the features of DF ignition and correctly predict IDTs, even for predictions outside the ranges of parameters used for learning. Compared to CNN, HDMR is more favorable due to its relatively weak dependence on the size of training data and its ability to assess the sensitivity of IDTs to input variables. The sensitivity analysis suggests that the mixing rate between the pilot fuel and the main fuel plays a critical role in affecting the DF ignition. The HDMR and/or CNN models are seen as promising alternatives to time-consuming experimental measurements or numerical calculations of IDTs.

The effect of counter-ion substitution on poly(phthalazinone ether ketone) amphoteric ion exchange membranes for vanadium redox flow battery

The study proposed a novel method to prepare poly(phthalazinone ether ketone) amphoteric ion exchange membranes (Q/S-M) with both increased efficiency and chemical stability for vanadium redox flow battery (VRB) applications. Q/S-M membranes were obtained after the successive amination and acidification process of blend base membranes prepared from brominated poly(phthalazinone ether ketone) (BPPEK) and sulfonated poly(phthalazinone ether ketone) substituted by counter-ions (SPPEK-M), where M was defined as counter-ions: Li+, Na+ and K+. The study analyzed the effect of counter-ion size on properties of Q/S-M membranes, which were compared with those for Q/S membrane obtained from BPPEK and SPPEK in acid form. Q/S and Q/S-M membranes maintained the same composition of ionic groups. The Q/S-M membranes induced by bigger counter-ion size showed the increasing of water content and ion diffusion rate, which was higher than that of Q/S membrane. Related to Q/S membrane, Q/S-K membrane possessed almost half area resistance (0.67 Omega cm(2) vs 1.43 Omega cm(2)), and the value was close to that of Nafion115. Q/S-M membranes exhibited a 96.0-98.8% decrease in VO2+ permeability over Nafion115. Q/S-K membrane displayed a 6.5% increase in VE and correspondingly a 6.2% increase in EE over Q/S membrane, maintaining superior EE than Nafion115 (89.7% vs 86.5%). The ex-situ degradation test in VO2+ solutions indicated that despite close EE, Q/S-K membrane showed superior chemical stability over amphoteric ion exchange membranes (AIEMs) in our previous works. There was no obvious efficiency decay of Q/S-K membrane during 100-cycles test, indicating the good duration in operating VRB.

Chemical transformation of renewable algae oil to polyetheramide polyols for polyurethane coatings

Algae are a group of photosynthetic marine or freshwater plants that exhibit high CO2 capturing capacity. Algae have been among the most promising renewable resources for overcoming climate change issues. In this study, algae oil (AO) was chemically transformed to polyols through two-step reactions and incorporated into value-added and industrially important polyurethane (PU) coatings. First, AO was reacted with diethanolamine to afford fatty amide. Then, polyetheramide polyols (AEAs) were prepared by reacting the fatty amide with bisphenol-A, 1,4-butanediol, or isosorbide. PU coatings were prepared by reaction between the AEAs and diphenylmethane diisocyanate. The PUs exhibited typical semicrystalline and three-step degradation behaviors with enhanced gel content values, supporting the high reactivity of the AEAs as polyols. The hydrophobic characteristics of the fatty acid chains of the AEAs resulted in decreased water absorption of the PUs, which improved the antimicrobial characteristics of the PUs. In particular, the PU coatings exhibited excellent resistance against alkaline aqueous media and organic solvent (xylene) along with reasonable gloss, hardness, flexibility. In saline aqueous media, the PU coatings exhibited anticorrosion performance superior to that of typical poly(tetramethylene ether) glycol-based PU coating. This study demonstrates the high potential of the PUs as anticorrosion and antimicrobial materials from the environmentally friendly renewable resource.
