A universal strategy to improve interfacial kinetics of solid supercapacitors used in high temperature

The growing application domain of energy storage devices (ESDs) is leading research to temperature tolerant supercapacitors. To realize reliable and safe devices, high modulus solid electrolytes are favored by most researchers. However, the inferior infiltrating ability of such electrolytes usually results in poor electrochemical performances of the ESDs. Herein, we adopted a hierarchical optimization strategy to address the aforementioned interfacial issues. Continuous ionic percolation throughout the hierarchical pores of the 3D electrode was formed by in-situ introducing an ionogel buffer layer. Benefiting from this, the rate of ions diffusing within electrodes was increased by 5 times. Furthermore, the kinetics of ions entering into nanopores was improved via introducing small size ions into ionic liquids (ILs) and adjusting the solvated structures. Both the capacity and rate performance of the electrochemical double layer capacitors (EDLCs) were improved. Additionally, the buffer layer exhibited sufficient thermostability to cooperate with poly(ether ether ketone) (PEEK)-based solid electrolyte. Consequently, the EDLCs exhibited excellent cycling stability (79% capacitance retention after 5000 cycles) at 120 degrees C and delivered a maximum energy density of 46.9 Wh kg(-1) with a power density of 926.9 W kg(-1). Our strategy is believed to be effective to cooperate with various solid electrolyte systems and offer a general design principle for durable and high performance EDLCs. (C) 2020 Elsevier Inc.

Cloud point extraction coupled with ultrasound-assisted back-extraction for determination of trace legacy and emerging brominated flame retardants in water using isotopic dilution high-performance liquid chromatography-atmospheric pressure chemical ionization-tandem mass spectrometry

Isotopic dilution high-performance liquid chromatography-atmospheric pressure chemical ionization-tandem mass spectrometry method was developed for determination of seven legacy and emerging brominated flame retardants (BFRs) in water using cloud point extraction coupled with ultrasound-assisted back-extraction. The effects of different experimental conditions on the recovery and matrix effect during cloud point extraction were investigated. Under the optimum conditions (sample volume: 40 mL; Triton X-114 concentration: 1.0 g L-1; equilibration temperature: 40 degrees C; equilibration time: 10 min; NH4OAc concentration: 0.5 M), the absolute recoveries obtained by cloud point extraction for the seven BFRs ranged from 64.0% to 108.8%, with matrix effect factors ranging between 0.70 and 1.07. Ultrasound-assisted back-extraction combined with isotope dilution mass spectrometry was utilized to enhance the enrichment factor and improve the repeatability. Under the optimized conditions, method limits of detection for BFRs ranged from 0.3 to 3.0 ng L-1. The average recoveries were in the range of 92.9-113.6% and 86.0-99.3% for spiked water samples at 10 and 100 ng L-1 of each BFR. The intra- and inter-day relative standard deviations (n = 6) were less than 5.4% and 8.0%, respectively. The results demonstrated that the proposed method was highly sensitive, efficient and reliable for the determination of trace legacy and emerging BFRs in water samples.

Synergy of Lewis and BrOnsted acid sites for polyoxymethylene dimethyl ether synthesis from methanol and formaldehyde solution over Zr4+ modified sulfonated resin

Polyoxymethylene dimethyl ether (PODEn) is a clean, effective and promising diesel additive. In this work, acidic sulfonated resin modified by zirconium (Zr4+-SR), which possess both Lewis and BrOnsted acid sites, was employed to catalyze the synthesis of PODEn from methanol (MeOH) and formaldehyde (FA) solution. The catalysts were investigated by various characterization methods including SEM, BET, XPS, FT-IR, NH3-TPD, Pyridine FT-IR, TG-MS and ICP-OES. It was found that the introduction of Zr4+ into cationic exchange resin formed the Lewis acid sites and improvement of the catalytic performance in PODEn synthesis from methanol and formaldehyde solution was attributed to the synergistic effect of Lewis and BrOnsted acid sites. With the increase of zirconium loading, the amount of Lewis acid sites and weak acidity of the Zr4+-SR catalyst increased gradually, and the catalytic activity of the catalysts for the PODEn synthesis reaction exhibited a trend of increasing first and then decreasing. In the methanol and formaldehyde solution, BrOnsted acid sites were active for the acetalization of hemiformal and methanol, while Lewis acid sites were conducive to the activation of the methylene glycol. A possible reaction route for the PODEn synthesis from methanol and formaldehyde solution was proposed. 61.1% methanol conversion, 98.7% PODE1-6 and 22.4% PODE3-6 selectivity were achieved under optimal reaction conditions. The reusability investigation of the Zr4+-SR catalyst showed a stable catalytic activity for the synthesis of PODEn from methanol and formaldehyde solution and revealed that the decrease of catalyst activity was attributed to the partial loss of the zirconium.

Effects of different levels of rapeseed cake containing high glucosinolates in steer ration on rumen fermentation, nutrient digestibility and the rumen microbial community

This trial was conducted to study the effects of dietary rapeseed cake (RSC) containing high glucosinolates (GLS) on rumen fermentation, nutrient digestion and the rumen microbial community in steers. Eight growing steers and four rations containing RSC (GLS 226.1 mu mol/g DM) at 0.00, 2.65, 5.35 and 8.00 % DM were assigned in a replicate 4 x 4 Latin square design. The results indicated that increasing RSC levels increased the ruminal concentration of thiocyanate (SCN) (P < 0.01), decreased the ruminal concentration of ammonia nitrogen (NH3-N) and the molar proportion of isovalerate (P < 0.05), did not affect the ruminal concentration of total volatile fatty acids (P > 0.05), decreased the crude protein (CP) digestibility (P < 0.05) and increased the ether extract (EE) digestibility (P < 0.01). Increasing RSC levels tended to decrease the abundances of ruminal Ruminobacter amylophilus (P = 0.055) and Ruminococcus albus (P = 0.086) but did not affect methanogens, protozoa, fungi and other bacteria (P > 0.05). Increasing RSC levels in the ration did not affect the ruminal bacterial diversity (P > 0.05), but it increased the operational taxonomic units and the bacterial richness (P < 0.05) and affected the relative abundances of some bacteria at the phylum level and genus level (P < 0.05). In conclusion, RSC decreased the ruminal concentration of NH3-N and the CP digestibility, increased the EE digestibility and partly affected the ruminal bacterial community. SCN, as the metabolite of GLS, could be a major factor affecting these indices. Interested yet?

A pyrolysis process coupled to a catalytic cracking stage: A potential waste-to-energy solution for mattress foam waste

Pyrolysis coupled to either thermal or catalytic cracking of mattress foam waste was performed in a laboratory-scale facility consisting of a fixed-bed reactor joined to a tubular cracking reactor. The results showed a great potential for the production of syngas specially at high cracking temperatures. Particularly, fixing 800 degrees C in the cracking reactor, a CO and CH4 rich gas with a remarkable amount of H-2 was obtained. The addition of catalysts (dolomite, olivine or HiFUEL (R)) significantly decreased undesirable tar formation, (below 10 wt%), simultaneously increasing the gas yield and keeping CO and CH4 as the main components in the stream, becoming a preferable route that the non-catalytic process. Accordingly, this stream could be used preferably for further applications in energy generation because its heating value ranged between 15.7 MJ/Nm(3) and 19.6 MJ/Nm(3). In particular, the gas obtained by the use of dolomite could be advantageous for the production of organic compounds such as dimethyl ether (DME) as well as its use an engine or boiler to generate electricity in small facilities. In addition, the solid fraction obtained after de process could be used as a medium quality refused derived fuel (LHV similar to 12 MJ/kg) in order to support the internal energy requirements of the process.

Synthesis of bio-based poly(methacrylates) using SG1-containing amphiphilic macroinitiators by nitroxide mediated miniemulsion polymerization

SG1-based amphiphilic macroinitiators were synthesized from oligoethylene glycol methyl ether methacrylate and 10 mol% acrylonitrile or styrene (as the controlling comonomer) to conduct the nitroxide mediated polymerization of bio-based methacrylic monomers (isobornyl methacrylate (IBOMA) and C13 alkyl methacrylate (C13MA)) in miniemulsion. The effect of the addition of surfactant (DOWFAX 8390), co-stabilizer (n-hexadecane) and different reaction temperatures (80, 90 and 100 degrees C) on polymerization kinetics was studied. We found that the NMP of IBOMA/C13MA using amphiphilic macroalkoxyamines were most effective during miniemulsion polymerization (linear trend of M-n versus conversion and high latex stability) in presence of 2 wt% surfactant and 0.8 wt% co-stabilizer (relative to monomer) at 90 degrees C. The effect of surfactant, co-stabilizer and temperature on particle size during the polymerization was studied and suggested a decrease in initial particle size with the addition of surfactant and co-stabilizer. Finally, the thermal properties of IBOMA/C13MA polymers, prepared by amphiphilic macroinitiators, were examined thoroughly, indicating a T-g in the range of -44 degrees C < T-g < 109 degrees C.
