One-pot Synthesis of Trifunctional Epoxy Resin and its Nanocomposite: Investigation of Thermal and Rheological Properties

Herein, in the present study, we developed the synthesis of new trifunctional epoxy resin (TER) namelytriglycidyl ether N,N bis (3-phenylamino propyl) 3-phenylamino propoxy phenyl and the elaboration of its nanocomposite. TER was characterized and confirmed using Fourier transform infrared and nuclear magnetic resonance spectroscopy. Further, the storage modulus and loss modulus for all formulated nanocomposite increase with the increase in the zinc oxide filler. The results of the thermogravimetric analysis confirm the amelioration in the thermal properties of different nanocomposites TER/MDA/ZnO crosslinked by methylene dianiline (MDA) and formulated by zinc oxide (ZnO) as a filler at varying mass percentage (0, 0.5, 1, and 2%).

Experimental and numerical study on the effect of oxymethylene ether-3 (OME3) on soot particle formation

The reduction and control of particulate matter generated by fossil fuel combustion are among the main issues for actual and future combustion devices due to the increasingly stringent emission regulations. Recently, various fuels have been investigated as a potential substitute or additive for diesel and gasoline. This work focuses on how oxymethylene ether-3 (OME3), the smallest promising OME compound, affects carbon particulate formation when blended with ethylene in burner-stabilized premixed flames at different equivalence ratios. Particle size distribution (PSD) and Laser-Induced Fluorescence (LIF) and Incandescence (LII) along with numerical (Conditional Quadrature Method of Moments – CQMOM, based on D’Anna physico-chemical soot model) investigations were conducted to study particle formation and growth in pure ethylene and ethylene/OME3 flames. The soot volume fraction and PSD indicate a reduction in the total number and the size of the soot particles at all equivalence ratios, while the number of small nanoparticles remains almost unchanged. The CQMOM model is able to predict similar trends for the soot volume fraction and, using the entropy maximization concept, the general shape of the PSD for both pure ethylene and OME3-blended flames, compared to the experimental measurements. Further, carbon particulate matter was thermophoretically sampled in the highest equivalence ratio conditions and spectroscopically analyzed. The soot structure was investigated using UV-Visible and Raman spectroscopy, finding a slightly higher aromaticity for the pure ethylene soot. FTIR analysis showed that carbon particulate matter produced from an OME3-doped flame contained larger amounts of oxygen, mainly in the form of C-O.

Visible-Light Promoted C-O Bond Formation with an Integrated Carbon Nitride-Nickel Heterogeneous Photocatalyst

Ni-deposited mesoporous graphitic carbon nitride (Ni-mpg-CNx) is introduced as an inexpensive, robust, easily synthesizable and recyclable material that functions as an integrated dual photocatalytic system. This material overcomes the need of expensive photosensitizers, organic ligands and additives as well as limitations of catalyst deactivation in the existing photo/Ni dual catalytic cross-coupling reactions. The dual catalytic Ni-mpg-CNx is demonstrated for C-O coupling between aryl halides and aliphatic alcohols under mild condition. The reaction affords the ether product in good-to-excellent yields (60-92 %) with broad substrate scope, including heteroaryl and aryl halides bearing electron-withdrawing, -donating and neutral groups. The heterogeneous Ni-mpg-CNx can be easily recovered from the reaction mixture and reused over multiple cycles without loss of activity. The findings highlight exciting opportunities for dual catalysis promoted by a fully heterogeneous system.

Reaction mechanisms and product patterns of Pteris vittata pyrolysis for cleaner energy

The pyrolysis behaviors, kinetics, evolved products, and optimization of aboveground (PA) and below ground (PB) biomass of Pteris vittata were quantified. The pyrolysis performance in response to the elevated heating rate was improved by 21.21 and 16.79 times for PA and PB, respectively. CH4 and CO emissions were produced more from the pyrolysis of PB than PA. The increased pyrolysis temperatures of PA and PB led to the three consecutive releases of C=O (alcohol, ketone, acid, and furan), C-O (alcohol, phenol, and ether), and CO2, CH4, H2O, and CO. The formations of NH3 and HCN were more sensitive to the temperature rise with PB than PA. PA produced alcohol/ketone and acids by 1.81 and 1.32 times what PB produced. PB produced furan and carbohydrate/alkene by 1.56 and 2.52 times what PA produced. PA appeared as a more suitable feedstock than PB and showed an optimal pyrolysis behavior at 545 degrees C and 45 degrees C/min. Our findings can provide the basis for characterizing the process and environmental benignity of the hyperaccumulator pyrolysis. (c) 2020 Elsevier Ltd. All rights reserved.

Ignition delay times of iso-butane activated by DME under various equivalence ratios in the shock tube

The ignition delay time of the high cetane number dimethyl ether (DME), high octane number i-butane, and their binary blends were investigated in a shock tube over the temperature range of 1091-1797 K, pressures of 2-10 atm, and equivalence ratios of 0.5-2.0. The LLNL iso-Octane Model and the DME sub-set of the Aramco3.0 Model were assembled together to reproduce the ignition delay behavior of the binary blends. Chemical kinetic analyses were conducted to understand the interplay between DME and i-butane at high temperatures. The ignition delay of DME and i-butane show the opposite equivalence ratio dependence under the current conditions. The promoting effect of DME addition on the ignition delay of i-butane becomes more significant as the equivalence ratio increases. The research result shows that there is no significant fuel to fuel interactions between DME and i-butane in the present conditions. The high reactivity of DME and its rapid accumulation of the free radicals lead to the promoted auto-ignition of i-butane.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 103-50-4 is helpful to your research. Application In Synthesis of Benzyl ether.

Printability and mechanical performance of biomedical PDMS-PEEK composites developed for material extrusion

Polydimethylsiloxane (PDMS) materials are widely adopted in the manufacture of facial prostheses, lab-on-chip devices and scaffolds for soft-tissue engineering applications; however, their processing by additive manufacturing (AM) has proved challenging. Liquid silicone rubbers (LSRs) are favoured for their high shape fidelity when cast, but their low viscosity and surface tension often prevent self-support, post-extrusion. Poly (ether) ether ketone (PEEK) particle reinforcement through interfacial bonding has proven to enhance key properties of PDMS, expanding their end-use functionality. Still, the impact of such particles on the printability of LSR-PDMS is not explored. In this study, for the first time, solvent-free biocompatible PDMS-PEEK composites (up to 30 wt% PEEK) were successfully characterised for material extrusion (ME) printing. Rheological analysis confirmed shear-thinning of all PDMS-PEEK composites under applied load (within the tolerances of the printer) and dominant storage moduli at rest (i.e. prints can self-support), considered highly desirable for ME-based printing. Attained rheological datasets were used to guide initial printability studies, which revealed finer track fidelity with rising fractional content of PEEK, at comparable print speed and displacement values. Composites with higher PEEK content demonstrated significant increases in Shore A hardness and stiffness (in tension and compression) in bulk form. Last but not least, enhanced shape fidelity (thanks to PEEK reinforcement) and geometrical autonomy further expanded the manufacturing freedom of PDMS, whereby infill density could be controlled in order to increase the range of mechanical performance, previously unachievable with conventional casting fabrication. Fundamentally, this could lead to the manufacture of bespoke spatially graded multi-material structures and devices that could be used to replicate the heterogenous properties of soft human tissues and in other advanced material applications.

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.

The influence of long carbon fiber and its orientation on the properties of three-dimensional needle-punched CF/PEEK composites

In this work, high performance composite materials with high mechanical strength and isotropic properties are expected to obtained. Long carbon fiber (40 mm) reinforced poly(ether ether ketone) (PEEK) composites were prepared by three-dimensional (3D) needle-punched method. Orthogonal test was used to optimize molding parameters of 3D needle-punched CF/PEEK (30/70) composites. The influence of carbon fiber content and its orientation on the mechanical properties, thermal properties, crystallization properties and microstructure of the composites were studied in the range of 30-60 wt %. The excellent mechanical properties were shown with the increase of fiber content, and the composites were approximately isotropic in-plane due to the random fiber orientation. With the increase of carbon fiber content, the melting point measured by differential scanning calorimetry (DSC) and 5% weight loss temperature tested by thermogravimetric analysis (TGA) of the composites increased slightly, however the heat deflection temperature (HDT) increased obviously. SEM observation showed that compared with traditional thermoplastic plate, 3D needle-punched CF/PEEK composites could provide multi-direction impregnation channel for PEEK melt resin to realize multi-point impregnation, as a result, carbon fiber had a better impregnation effect in PEEK resin matrix. It was found that the tensile modulus and flexural modulus of CF/PEEK were very close to those of human cortical bone. It would reduce the stress shielding effect and has great application value if it is applied to the orthopaedic bone plate.

Composite solid polymer electrolyte with silica filler for structural supercapacitor applications

Structural supercapacitors are energy storage devices that can function as structural materials. We synthesized composite solid polymer electrolytes (CSPEs) from 1-ethyl-3-methylimidazolium trifluoromethanesulfonate ([EMIm][OTF]), poly (ethylene glycol) monomethyl ether acrylate (PEGA) and functionalized silica filler. Two types of fumed silica were used: one had an unmodified surface, and the other an organically modified surface. The CSPEs were prepared by adding ionic liquids (IL) to the PEGA and the ratios between PEGA and IL were 7: 3 and 5: 5, respectively. The functionalized silica was synthesized by the sol-gel method under acidic conditions using methacryloxypropyl trimethoxysilane (MAPTMS), whereas the effects of silica filler on the electrochemical and thermal properties of CSPEs were investigated using electrochemical impedance spectroscopy, cyclic voltammetry, and differential scanning calorimetry. The ionic conductivity of CSPEs based on PEGA/[OTF]_SiO2 at various concentrations of [EMIm][OTF] was 5.7×10(-4) and 4.8×10(-4)S/cm, and their specific capacitance was 10.0 and 9.5 F/g, respectively. With the addition of silica filler, the ionic conductivity and specific capacitance of the synthesized CSPEs were lower than those of the neat CSPEs.
