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.

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.

Effects of Decabrominated Diphenyl Ether Exposure on Growth, Meat Characteristics and Blood Profiles in Broilers

Simple Summary Decabrominated diphenyl ether (BDE-209) has been widely used in recent decades, and its cumulative toxicity to crops, animals and human beings is attracting increasing attention. In this study, we established broiler models to investigate the effects of BDE-209 exposure at doses of 0, 0.02, 0.4 and 4 mg/kg on growth, carcass traits, meat quality, blood profiles and antioxidant capacity. Our results suggested that BDE-209 exposure altered the blood profiles and carcass traits and exhibited toxicity in liver and kidney functions. Furthermore, BDE-209 increased plasma malondialdehyde (MDA) concentrations and decreased the activities of glutathione peroxidase (GSH-px) and superoxide dismutase (SOD), which implied aggravating oxidant stress and decline of antioxidant capacity in broilers. Decabrominated diphenyl ether (BDE-209) is widely used as a flame retardant and is detected at high levels in the environment. Its toxicities have been reported and have attracted attention. In the present study, broilers were used to determine the response in growth performance, carcass traits, meat quality, blood profiles and antioxidant system to BDE-209 exposure at doses of 0, 0.02, 0.4 and 4 mg/kg. The results showed that BDE-209 exposure at levels of 0.02 or 0.4 mg/kg increased feed intake and decreased feed efficiency. BDE-209 altered the blood profiles, such as reducing the numbers of white blood cells, lymphocytes and neutrophilic granulocytes. As compared with the control, BDE-209 exposure significantly increased abdominal fat percentages of broilers at 64.9-159.5% and adversely affected the selected biochemical indicators, including alkaline phosphatase (ALP), aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatine (CRE), which indicated its toxicity to liver and kidney functions. Moreover, BDE-209 exposure significantly increased plasma malondialdehyde (MDA) concentrations and decreased the activities of glutathione peroxidase (GSH-px) and superoxide dismutase (SOD), which implied aggravating oxidant stress and decline of antioxidant capacity in broilers. In conclusion, our data demonstrated that the environmental pollutant BDE-209 adversely influenced growth performance, increased the deposition of abdominal fat, impaired antioxidant capacity and the immune system and had potential toxicity to the liver and kidney of broilers.

Effect of soybean oil/PODE/ethanol blends on combustion and emissions on a heavy-duty diesel engine

In this study, an experimental study has been conducted to explore the effects of soybean oil/PODE/ethanol blends on the combustion and emission characteristics in a diesel engine. Three tested fuels are 70% soybean oil/30% PODE by volume denoted as S70P30, 70% soybean oil/15% PODE/15% ethanol by volume denoted as S70P15E15 and baseline pure diesel denoted as D100. The impacts of CA50 and combustion duration at engine speed of 1415 rpm and 1.15 MPa BMEP are investigated. As the CA50 delays, BTE and NOx emissions decrease and soot emissions increase; as the combustion duration prolongs, BTE increases first and then decreases, NOx emissions decrease and soot emissions increase. CA50 has more significant effect on BTE, NOx and soot emissions than combustion duration. At the same CA50 and combustion duration, the trend in BTE and soot emissions is D100 > S70P15E15 > S70P30; for NOx emissions the trend is S70P30 > S70P15E15 > D100. For example, When CA50 is 17 degrees CA ATDC and the combustion duration is 25 degrees CA, the BTE of D100, S70P15E15 and S70P30 are 41.0%, 39.1% and 38.6%, respectively; the NOx emissions are approximately 6.4 g/kW.h, 7.0 g/kW.h and 7.8 g/kW.h, respectively; the soot emissions are 0.004 g/kW.h, 0.0011 g/kW.h and 0.0008 g/kW.h, respectively. Finally, the WHSC test cycle of Euro VI regulation is performed. Comparing two soybean oil blended fuels, S70P15E15 and S70P30 are similar in soot emissions, but S70P15E15 is lower in NOx emissions and weighted BSFC.

Parallel Lipid Peroxide Accumulation Strategy Based on Bimetal-Organic Frameworks for Enhanced Ferrotherapy

Ferroptosis, a nonapoptotic cell-death pathway, is commonly regulated by ether lipid peroxide generation or glutathione consumption. In this work, a parallel lipid peroxide accumulation strategy was designed based on catalytic metal-organic frameworks (MOFs) for enhanced ferrotherapy. The bimetallic MOF was synthesized with iron porphyrin as a linker and cupric ion as a metal node, and erastin, a ferroptosis inducer, was sandwiched between the MOF layers with 4,4 ‘-dipyridyl disulfide as spacers. In a tumor microenvironment, erastin was released from the layered MOFs through glutathione-responsive cleavage. The exfoliated MOFs served as a dual Fenton reaction inducer to generate numerous hydroxyl radicals for the accumulation of lipid peroxide, while erastin-aggravated glutathione depletion down-regulated glutathione peroxidase 4; this then inhibited the consumption of lipid peroxide. Therefore, a parallel lipid peroxide accumulation strategy was established for enhanced ferrotherapy that effectively inhibited tumor growth in live mice, opening up new opportunities to treat apoptosis-insensitive tumors.

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 1836-62-0. Product Details of 1836-62-0.

Proton exchange composite membranes comprising SiO2, sulfonated SiO2, and metal-organic frameworks loaded in SPEEK polymer for fuel cell applications

Proton exchange membrane fuel cell (PEMFC) is a promising technology that offers a clean and efficient renewable energy source. The hybrid SiO2, sulfonated SiO2 (S-SiO2), and metal-organic framework-5 (MOF-5) incorporated sulfonated poly (ether ether ketone) (SPEEK) ternary composite membranes are fabricated using dry phase inversion technique for PEMFC. The membrane performance is evaluated in terms of water uptake, ion exchange capacity, methanol permeability, and proton conductivity (PC) measurements. The morphological study of fabricated membranes was carried out using scanning electron microscopy and atomic force microscopy analysis. The mechanical stability is strengthened up to 30-40%, and the PC gets enhanced with the incorporation of MOF-5, achieving simultaneous improvement in proton conduction and membrane stability. The PC of the ternary SPEEK/S-SiO2/MOF-5 membrane is 3.69 x 10(-3) S cm(-1), 32% more than the neat membrane. A significant increase in selectivity of 23% is observed by incorporating S-SiO2 and MOF-5 fillers when compared with the neat membrane. The synergistic effect of MOF-5 and S-SiO2 in the ternary membrane has significantly improved water retention and proton conductivity. The functional -SO3H groups of SiO2 and MOF-5 bonded via acid-base electrostatic interactions with the SPEEK; enhances proton conduction accompanied by suppressing the methanol penetration through membranes.

A novel interaction mechanism in lignin pyrolysis: Phenolics-assisted hydrogen transfer for the decomposition of the beta-O-4 linkage

Pyrolysis of lignin involves complex unimolecular decomposition and bimolecular interaction mechanisms. Unimolecular decomposition of lignin model compounds has been widely investigated, while bimolecular interactions are far from well elucidated. Currently, only two radical reaction-based interactions, i.e., hydrogen abstraction and hydrogen-bond-induced homolysis mechanisms, have been proposed to explain the interactions in the lignin pyrolysis process, which ignores the concerted reaction-based interactions involving the pyrolytic products of lignin. Particularly, a large number of phenolics are produced in the pyrolysis of lignin, which can further affect the concerted pyrolysis reactions of lignin. In the present work, a novel interaction mechanism, phenolics-assisted hydrogen transfer (phenolics-AHT) pro cess for the concerted reactions, is confirmed and carefully investigated. Phenylethyl phenyl ether (PPE), a typical beta-O-4 lignin dimer, is used as the model compound to reveal the phenolics-AHT mechanism in the lignin pyrolysis system. Density functional theory (DFT) calculation, electrostatic potential (ESP) analysis, and fast pyrolysis experiment results are combined to reveal that the phenolic products participate in the hydrogen transfer process of the concerted Maccoll elimination reaction by means of their phenolic hydroxyl structures and significantly reduce the energy barrier, thus promoting the cleavage of the beta-O-4 linkage. On the contrary, phenolics-AHT has no obvious effect on the concerted retro-ene fragmentation. At medium pyrolysis temperatures, the hydrogen transfer processes induced by phenolic products play a more significant role in the dissociation of the beta-O-4 linkage than the hydrogen abstraction induced by radicals, due to the limited amount of free radicals. In addition, DFT calculation results further suggest that decarbonylation, decarboxylation, dehydration, tautomerism, and other concerted reactions can also be promoted by phenolics-AHT.
