Recent advances in ring-opening of donor acceptor cyclopropanes using C-nucleophiles

Ring-opening transformations of donor-acceptor cyclopropanes (DAC) with carbon-centered nucleophiles is a simple, straight-forward approach to 1,3-bifunctional compounds that has witnessed remarkable progress over the past several years. To date, different reactivity patterns of DACs have been successfully exploited in racemic/stereoselective syntheses of various acyclic compounds or carbocycles with an impressive structural diversity. The thriving strategies have been successfully utilized in multistep synthesis of complex target molecules. Herein, the recent advances (2015-present) in the ring-opening of DAC involving electron rich arenes and indoles, active methylene compounds, various dipolarophiles, organoborates/boronates, vinyl ethers etc. following Friedel-Crafts alkylation, annulation/formal cycloaddition reaction, organocatalytic reaction, Nazarov cyclisation etc. are presented.

Electropolymerizable isocyanate-based electrolytic additive to mitigate diffusion-controlled self-discharge for highly stable and capacitive activated carbon supercapacitors

To mitigate the self-discharge of supercapacitors (SCs), numerous researches have reported about the effective use of cell resistance, although this might provoke a deterioration of charge/discharge performances. In this work, isocyanate-based electrolytic additive, 2-isocyanatoethylmethacrylate (ICEMA), is polymerized by two methods, in-situ electropolymerization (EP) and radical-polymerization (RP), on activated carbon (AC) electrode to mitigate the diffusion-controlled self-discharge, which is a major contribution to the self-discharge herein. Although the radical-polymerized PICEMA reveals favorable suppression of self-discharge, only confined in bulk electrolyte and meso-region, this exhibits severe increases in all impedance parameters and deteriorated charge/discharge capabilities. The electropolymerized PICEMA, however, meets the bifunctional perspective, revealing aptly retained capacitance and suppressed self-discharge behavior throughout microand meso-regions. ICEMA is effectively electropolymerized on positive AC electrode at + 0.9 similar to 1.2 V (vs. AC), which is confirmed by the electrochemical impedance spectroscopy, electrochemical quartz microbalance, and X-ray photoelectron spectroscopy. The functionality of isocyanate group to suppress self-discharge is also confirmed by comparing methoxy group of ethylene glycol methyl ether methacrylate (EGMEMA). (C) 2021 Elsevier Ltd.

Comparative Study on Toughening Effect of PTS and PTK in Various Epoxy Resins

This study investigated the toughening effect of in situ polytriazoleketone (PTK) and polytriazolesulfone (PTS) toughening agent when applied to various epoxy resins, such as diglycidyl ether of bisphenol A (DGEBA), diglycidyl ether of bisphenol F (DGEBF), and triglycidyl p-aminophenol (TGAP) with 3,3 ‘-diaminodiphenylsulfone as a curing agent. The fracture toughness, tensile properties, and thermal properties of the prepared epoxy samples were evaluated and compared. When PTK was mixed with DGEBF, the fracture toughness was improved by 27% with 8.6% increased tensile strength compared to the untoughened DGEBF. When PTS was mixed with TGAP, the fracture toughness was improved by 51% without decreasing tensile properties compared to the untoughened TGAP. However, when PTK or PTS was mixed with other epoxy resins, the fracture toughness decreased or improved with decreasing tensile properties. This is attributed to the poor miscibility between the solid-state monomer of PTK (4,4 ‘-bis(propynyloxy)benzophenone (PBP)) or PTS (4,4 ‘-sulfonylbis(propynyloxy)benzene (SPB)) and the epoxy resin, resulting in the polymerization of low molecular weight PTK or PTS in epoxy resin. Therefore, the toughening effect of PTK or PTS can be maximized by the appropriate selection of epoxy resin based on the miscibility between PBP or SPB and the resin.

Impact of increased injector nozzle hole diameters on engine performance, exhaust particle distribution and methane and formaldehyde emissions during dimethyl ether operation

E-Fuels can play a significant role in decarbonizing the transport sector. Among the potential E-fuels, dimethyl ether is a promising candidate for the combustion in compression ignition engines. Together with methanol, it can be produced from synthesis gas in a combined single-step process. However, due to the low volumetric heating value of dimethyl ether, the fuel injection system has to be modified to realize higher fuel flow rates. In this study, two injectors with increased nozzle hole diameters have been investigated, and their impact on engine performance, particle number distribution and formaldehyde as well as methane emissions was assessed. It was found that with dimethyl ether as fuel, the indicated efficiency at high load could be increased by over 1% compared to operation with conventional diesel fuel. The main reason for this is lower wall heat loss. Furthermore, almost no particle emission was found during dimethyl ether operation with the smaller nozzle. With the larger nozzle hole diameter, increased particle concentrations were measured at high loads. But these were still much lower compared to the corresponding diesel fuel combustion. Regarding formaldehyde and methane, higher emissions were found for the dimethyl ether combustion compared to diesel fuel combustion. It is assumed that this is due to the increased formaldehyde and methane production of dimethyl ether during high temperature pyrolysis and oxidation. The increased hydrocarbon emissions could have been caused by fuel dripping from the nozzle after the end of the injection event.

Low-Flammable Parahydrogen-Polarized MRI Contrast Agents

Many MRI contrast agents formed with the parahydrogen-induced polarization (PHIP) technique exhibit biocompatible profiles. In the context of respiratory imaging with inhalable molecular contrast agents, the development of nonflammable contrast agents would nonetheless be highly beneficial for the biomedical translation of this sensitive, high-throughput and affordable hyperpolarization technique. To this end, we assess the hydrogenation kinetics, the polarization levels and the lifetimes of PHIP hyperpolarized products (acids, ethers and esters) at various degrees of fluorine substitution. The results highlight important trends as a function of molecular structure that are instrumental for the design of new, safe contrast agents for in vivo imaging applications of the PHIP technique, with an emphasis on the highly volatile group of ethers used as inhalable anesthetics.

Green extraction of perilla volatile organic compounds by pervaporation

Volatile organic compounds (VOCs) present in perilla essential oil are of high interest in medicinal and food processing. In this work, pervaporation was implemented to extract the valuable perilla VOCs from dilute aqueous solutions as a green process. Three representative VOCs of perilla (i.e., limonene, linalool, and perillaldehyde) having different functional groups were selected as model components, and poly(ether-block-amide) (PEBA) and polydimethylsiloxane (PDMS) membranes were prepared for the VOC extraction studies. The influences of operating conditions (i.e., feed concentration and temperature) on the pervaporation performance of the membranes were investigated. In binary VOC/water mixtures, an increase in the feed concentration increased the VOC flux and decreased the separation factor. The VOC flux also increased significantly with temperature, mainly due to an augmented driving force for permeation. The impact of the coupling effects in multicomponent permeation was evaluated by comparing the pervaporation performance of VOCs in binary VOC/water and quaternary VOCs/water systems. Results show that the VOC permeation behavior was affected by the presence of other VOCs, depending on the permeant-permeant and membrane-permeant interactions. Based on pervaporation separation index, the PEBA membrane showed a better overall separation efficiency than the PDMS membrane for the extraction of perilla VOCs. Since pervaporation does not involve any chemical solvents and operates at moderate temperatures, it provides a green process for extracting valuable perilla VOCs.

Fabrication of PBI/SPOSS hybrid high-temperature proton exchange membranes using SPAEK as compatibilizer

Because of the harsh operating circumstances of high temperature over 100 degrees C and strong acidity, it is of great significance to explore some new methods on the developments of high-performance membrane materials using in high-temperature proton exchange membrane fuel cells (HT-PEMFCs). In current work, with the assistance of newly designed sulfonated poly (aryl ether ketone) (SPAEK) compatibilizer, some hydrophilic and acidophilic polyhedral-oligosilsesquioxane nanoparticles bearing sulfuric acid groups (SPOSS) were successfully incorporated into a soluble arylether-type polybenzimidazole (Ph-PBI) matrix via an in situ sol-gel process to obtain a new family of hybrid membranes with an improved overall performance. As a result, these hybrid membranes exhibited enhanced acid absorption ability and doping levels at 120 degrees C, improved acid retention ability and attractive mechanical-dimensional stability. More importantly, the proton conductivity of a phosphoric acid doped hybrid membrane reached 126 mS cm(-1) at 200 degrees C. This membrane was also suitable for membrane electrode assemblies (MEAs), and a maximum power density of 300 mW cm(-2) could be achieved at 160 degrees C without humidity.

First insights into the formation and long-term dynamic behaviors of nonextractable perfluorooctanesulfonate and its alternative 6:2 chlorinated polyfluorinated ether sulfonate residues in a silty clay soil

Per- and polyfluoroalkyl substances (PFAS) are persistent and toxic contaminants that are ubiquitous in the environment. They can incorporate into soil as nonextractable residues (NER) which are not detectable with conventional analytical protocols but are still possible to remobilize with changes of surrounding conditions, and thus will be bioavailable again. Therefore, there is a need to investigate thoroughly the long-term fate of NER-PFAS. In this study, a 240-day incubation of perfluorooctanesulfonate (PFOS) and its alternative 6:2 chlorinated polyfluorinated ether sulfonate (F-53B) in a silty clay topsoil was carried out. Solvent extraction, alkaline hydrolysis and sequential chemical degradation were applied on periodically sampled soil to obtain extractable, moderately bound and deeply bound PFAS, respectively. The results confirmed the formation of NER of both compounds but with different preferences of incorporating mechanisms. NER-PFOS was formed predominantly by covalent binding (via head group) and strong adsorption (via tail group). The formation of NER-F-53B was mainly driven by physical entrapment. Both bound compounds within the incubation period showed three-stage behaviors including an initial period with slight release followed by a (re) incorporating stage and a subsequent remobilizing stage. This work provides some first insights on the long-term dynamic behaviors of nonextractable PFAS and will be conducive to their risk assessment and remediation (e.g. estimating potential NER-PFAS level based on their free extractable level, and selecting remediation methods according to their prevailing binding mechanisms).

An Attempt to Formulate Non-Carbonate Electrolytes for Sodium-Ion Batteries

Non-aqueous carbonate solvents have been the main choice for the development of lithium-ion batteries, and similarly most research on sodium-ion batteries have been performed using carbonate-based solvents. However, the differences between sodium and lithium batteries – in term chemistry/electrochemistry properties as well as electrode materials used – open up opportunities to have a new look at solvents that have attracted little attention as electrolyte solvent. This work investigates properties of a wide range of different solvent classes in the context of sodium-ion battery electrolytes and compares them to the performance of propylene carbonate. The thirteen solvents studied here include one or several members of glymes, carbonates, lactones, esters, pyrrolidones, sulfones, and alkyl phosphates. Out of those, five outperforming solvents of gamma-butyrolactone (GBL), gamma-valerolactone (GVL), N-methyl-2-pyrrolidone (NMP), propylene carbonate (PC), and trimethyl phosphate (TMP) were further investigated using additives of ethylene sulfite (ES), vinylene carbonate (VC), fluoroethylene carbonate (FEC), prop-1-ene-1,3-sultone (PES), sulfolane (TMS), tris(trimethylsilyl) phosphite (TTSPI), and sodium bis(oxalato)borate (NaBOB). The solvents TMS and tetraethylene glycol dimethyl ether (TEGDME) were tested in 1 : 1 mixtures by volume with the co-solvents; NMP, dimethoxyethane (DME), and TMP. All electrolytes used NaPF6 as the salt. Primary evaluation relied on electrochemical cycling of full-cell sodium-ion batteries consisting of Prussian white cathodes and hard-carbon anodes. Galvanostatic cycling was performed using both two- and three-electrode cells, in addition, cyclic and linear sweep voltammetry was used to further evaluate the electrolyte formulations. Moreover, the resistance was measured on the anode and cathode, using Intermittent current interruption (ICI) technique.

Dielectric properties of sulfonated poly(ether ether ketone) (SPEEK) electrolytes with 1-ethyl-3-methylimidazolium tetrafluoroborate salt: Ionic liquid-based conduction pathways

In this study, dielectric properties of sulfonated poly(ether ether ketone) (SPEEK) solid polymer electrolytes (SPEs) containing room-temperature molten salt, 1-ethyl-3-methylimidazolium tetrafluoroborate were investigated. Additionally, the effects of ionic liquid (IL) addition on the thermomechanical properties and the microstructure of composite electrolytes (SPEEK-30 x 1IM and SPEEK-30 x 2IM) were studied. The characteristics of the SPEs were investigated by FTIR, SEM, TGA, DSC and DMA measurements. FTIR analysis confirmed the success of the sulfonation process and IL/sulfonated polymer interactions. IL addition caused changes in the crystalline structure and surface morphology of the SPEs. It was observed that SPEEK-30 x 1IM and SPEEK-30 x 2IM electrolytes have lower glass transition temperatures (T-g) and crystallinity than that of pure SPEEK-30. Due to the amorphous character formed by IL, proton conduction paths in which ILs exhibit enhanced conductivity have been formed. Among the composite electrolytes, SPEEK-30 x 2IM demonstrated an ionic conductivity (5.45 x 10(-4) Scm(-1)) more than 20 times higher than SPEEK-30.
