Experimental characterization of n-heptane low-temperature oxidation products including keto-hydroperoxides and highly oxygenated organic molecules (HOMs)

The oxidation of n-heptane was performed in a jet-stirred reactor USR) at 10 atm, an equivalence ratio of 0.5, and an initial fuel concentration of 1000 ppm at a residence time of 1 s in the temperature range 580-790 K (from cool-flame, negative temperature coefficient NTC, to intermediate temperature oxidation regime), and with 5000 ppm of fuel at 647 K and a residence time of 1.5 s. Low-temperature products formed in JSR were characterized using high-resolution mass spectrometry analyses (HRMS). Atmospheric pressure chemical ionizations (APCI) was used in positive and negative modes for MS analyses. Both flow injection analyses (FIA) or ultra-high-pressure liquid chromatography-Orbitrap (R) coupling were used to characterize hydroperoxides (C7H16O2), keto-hydroperoxides (C7H14O3), cyclic ethers (C7H14O), carboxylic acids (C2H4O2, C3H6O2, C4H8O2), ketones (C3-5H6-10O), diones (C7H12O2), and highly oxygenated molecules (C7H14O5, C7H14O2, C7H14O9, C2H14O11) resulting from the addition of up to six O-2 molecules on fuel radicals. H/D exchange with D2O was used to confirm the presence of -OH or -OOH groups in the products. Several available kinetic reaction mechanisms were tested against the present measurements of keto-hydroperoxides showing significant discrepancies. (C) 2020 The Combustion Institute.

Poly(Alkyl-Terphenyl Piperidinium) Ionomers and Membranes with an Outstanding Alkaline-Membrane Fuel-Cell Performance of 2.58 W cm(-2)

Aryl-ether-free anion-exchange ionomers (AEIs) and membranes (AEMs) have become an important benchmark to address the insufficient durability and power-density issues associated with AEM fuel cells (AEMFCs). Here, we present aliphatic chain-containing poly(diphenyl-terphenyl piperidinium) (PDTP) copolymers to reduce the phenyl content and adsorption of AEIs and to increase the mechanical properties of AEMs. Specifically, PDTP AEMs possess excellent mechanical properties (storage modulus>1800 MPa, tensile strength>70 MPa), H-2 fuel-barrier properties (<10 Barrer), good ion conductivity, and ex-situ stability. Meanwhile, PDTP AEIs with low phenyl content and high-water permeability display excellent peak power densities (PPDs). The present AEMFCs reach outstanding PPDs of 2.58 W cm(-2) (>7.6 A cm(-2) current density) and 1.38 W cm(-2) at 80 degrees C in H-2/O-2 and H-2/air, respectively, along with a specific power (PPD/catalyst loading) over 8 W mg(-1), which is the highest record for Pt-based AEMFCs so far.

Chemiluminescence-promoted oxidation of alkyl enol ethers by NHPI under mild conditions and in the dark

The hydroperoxidation of alkyl enol ethers using N-hydroxyphthalimide and molecular oxygen occurred in the absence of catalyst, initiator, or light. The reaction proceeds through a radical mechanism that is initiated by N-hydroxyphthalimide-promoted autoxidation of the enol ether substrate. The resulting dioxetane products decompose in a chemiluminescent reaction that allows for photochemical activation of N-hydroxyphthalimide in the absence of other light sources.

Two transition metal coordination polymers: Fluorescent sensing property and capability of treating neuropathic pain via regulating the ephrinBs-EphBs signaling pathway

By using a tripodal ether-connector tricarboxylic ligand 1,3,5-tris(carboxymethoxy)benzene (H3TCMB) as the organic linker, two new transition metal coordination polymers (CPs) were synthesized via reaction of Zn(NO3)(2)center dot 6H(2)O or Co(NO3)(2)center dot 6H(2)O with H3TCMB ligand under the solvothermal reaction conditions, and their chemical formulae are [Co-3(TCMB)(2)(H2O)(4)](n)center dot 4nH(2)O (1) and [Zn-3(TCMB)(mu(3)-OH)(3)](n)center dot 0.5nH(2)O (2). The single crystal X-ray diffraction study shows that complex 1 is a 2D layered network which is further extended into a 3D supramolecular network via H-bond interactions, and complex 2 shows a 2D layered structure based on a [Zn-3(mu(3)-OH)(3)](n) cluster-based unit. As expected, complex 2 displays excellent luminescence in the solid state and solution, and it could serve as an ultrasensitive fluorescent sensor for detection of 2,4,6-Trinitriphenol (PA). The therapeutic activity of these two compounds on neuropathic pain was evaluated. First, the expression levels of ephrinB receptor were detected via the real-time RT-PCR method, the results showed that ephrinB receptor expression levels in the sciatic nerve was significantly reduced by compound 1, but compound 2 did not show such effect. Then, the EphB ligand content was determined through the ELISA test, the results indicated that compound 1 was found more effective than compound 2 in reducing the content of EphB in the sciatic nerve.

Multifaceted pH and Temperature Induced Self-Assembly of P(DMAEMA-co-LMA)-b-POEGMA Terpolymers and Their Cationic Analogues in Aqueous Media

This work focuses on the synthesis of novel amphiphilic block terpolymers of the type poly[(2-(N,N-dimethylamino) ethyl methacrylate)-co-(lauryl methacrylate)]-b-poly[(oligo ethylene glycol) methyl ether methacrylate] (P(DMAEMA-co-LMA)-b-POEGMA)) by reversible addition-fragmentation chain transfer polymerization. The cationic amphiphilic polyelectrolyte analogs P(QDMAEMA-co-LMA)-b-POEGMA are obtained through quantitative quaternization of the DMAEMA segments. Molecular characterization by size exclusion chromatography, nuclear magnetic resonance, and Fourier Transform Infrared spectroscopies indicates the successful synthesis of these novel series of block terpolymers. The amine forms of the block copolymers respond to pH and temperature changes in aqueous solutions by forming unimolecular or multichain nanoaggregates of varying size, micropolarity, and internal structure, as indicated by light scattering and fluorescence spectroscopy techniques. At neutral and basic pH, the existence of micellar like nanoassemblies is observed in the solutions of P(DMAEMA-co-LMA)-b-POEGMA terpolymers, while aggregation into micellar-like clusters take place at temperature values above room temperature due to the presence of the hydrophobic LMA segments. Unexpectedly, the cationic polyelectrolytes P(QDMAEMA-co-LMA)-b-POEGMA counterparts show temperature responsiveness as a consequence of the amphiphilicity of the polymeric system.

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 5111-65-9 is helpful to your research. SDS of cas: 5111-65-9.

Microwave-assisted chemistry: parametric optimization for catalytic degradation of lignin model compounds in imidazolium-based ILs

Lignin, a readily available form of biomass with a potential source of aromatic chemical compounds, has not been fully utilized due to its complex structure. Hence, this study aims to elaborate and optimize the effects of parametric microwave conditions for the catalytic degradation of lignin model compounds. In addition to that, 41 types of imidazolium-based Ionic liquids were employed for the conversion of lignin model compounds such as guaiacol and benzyl phenyl ether. The microwave-assisted conversion of lignin model compounds in imidazolium-based ionic liquids was performed at optimum applied microwave power 700 W and 30-min irradiation time. The percentages conversion and yield were quantified using high-performance liquid chromatography (HPLC) analysis. Results revealed that the chloride anion-based ionic liquids exhibited better nucleophilic behavior and catalyzed the cleavage of ether-based compounds efficiently under microwave irradiation. Among the imidazolium-based ionic liquids, 1H-methylimidazolium chloride ([1H-MIM][Cl]) exhibited better performance with guaiacol conversion and catechol yield of 99% and 81%, respectively. Therefore, the microwave-assisted technique was found to be more promising than conventional methods for the ionic liquid-based catalytic degradation of lignin model compounds.

Thermal characterizations of basalt fiber-reinforced poly(aryl-ether-ketone) biomedical composites

This research article deals with the development and characterization of poly(aryl-ether-ketone) (PAEK) reinforced with 10 mass%, 20 mass% and 30 mass% of basalt fibers; the samples are titled as PABA 1, PABA 2 and PABA 3, respectively. The composite samples are prepared by hot compression molding process, and test specimens are prepared to ASTM standards. The prepared specimens are subjected to various thermal analyses. The results reveal that differential scanning calorimetry curve shows high crystallization temperature and melting enthalpy for 20 mass% basalt fiber in PAEK composite compared to other composites. The percentage of crystallinity is also higher, which indicates the purity of PABA 2. The same composite shows low mass loss with increase in degradation temperature in the thermogravimetric analysis, due to high heat resistance capacity and thermal barrier of PAEK/basalt fiber at this particular mass%. Dynamic mechanical analysis of 20 mass% basalt fiber PAEK composite shows better storage modulus and low loss modulus compared to 10 and 30 mass% basalt fiber/PAEK composites. The PABA 2 composite has minimum damping coefficient which indicates better stiffness and suitability for high-performance applications. The scanning electron microscope images show a good affinity between the matrix and the fiber in all the composites. Agglomeration of fibers in matrix is observed when loaded beyond 20 mass%; this may be due to lack of melt flow during hot compression.

Quaternion Algebra on 4D Superfluid Quantum Space-Time: Can Dark Matter Be a Manifestation of the Superfluid Ether?

Quaternions are a natural framework of 4D space-time, where the unit element relates to time, and three others relate to 3D space. We define a quaternion set of differential torsion operators (shifts with rotations) that act to the energy-momentum tensor written on the same quaternion basis. It results in the equations of gravity-torsion (gravitomagnetic) fields that are similar to Maxwell’s equations. These equations are parent equations, generating the following equations: (a) equations of the transverse gravity-torsion waves; (b) the vorticity equation describing vortices orbital speed of which grows monotonically in the vortex core but far from it, it goes to a permanent level; (c) the modified Navier-Stokes equation leading to the Schrodinger equation in the nonrelativistic limit and to the Dirac equation in the relativistic limit. The Ginsburg-Landau theory of superfluidity resulting from the Schrodinger equation shows the emergence of coupled proton-antiproton pairs forming the Bose-Einstein condensate. In the final part of the article, we describe Samokhvalov’s experiment with rotating nonelectric, nonferromagnetic massive disks in a vacuum. It demonstrates an unknown force transferring the rotational moment from the driving disk to a driven one. It can be a manifestation of the dark matter. For studying this phenomenon, we propose a neutron interference experiment that is like the Aharonov-Bohm one.

Is Palm Kernel Cake a Suitable Alternative Feed Ingredient for Poultry?

Simple Summary Supply of raw materials such as corn and soybean meal as livestock and poultry feeds may be limited and is a significant concern during the Covid-19 pandemic especially for the countries that depend on importation of raw materials. Consequently, the palm kernel cake has been proposed as an alternative raw material for animal feeds to reduce importation dependency. The chemical composition of palm kernel cake varies depending on the method of oil extraction. The crude fiber content of palm kernel cake is acceptable to most ruminants but is considered high for poultry. Biodegradation of palm kernel cake through solid-state fermentation can improve its nutritional quality, improving broiler health status and growth performance. Palm kernel cake (PKC), a by-product of oil extracted from palm nuts through expeller press or solvent extraction procedures is one of the highest quantities of locally available and potentially inexpensive agricultural product. PKC provides approximately 14-18% of crude protein (CP), 12-20% crude fiber (CF), 3-9% ether extract (EE), and different amounts of various minerals that feasible to be used as a partial substitute of soybean meal (SBM) and corn in poultry nutrition. Poultry’s digestibility is reported to be compromised due to the indigestion of the high fiber content, making PKC potentially low for poultry feeding. Nevertheless, solid-state fermentation (SSF) can be applied to improve the nutritional quality of PKC by improving the CP and reducing CF content. PKC also contains beta-mannan polysaccharide, which works as a prebiotic. However, there is a wide variation for the inclusion level of PKC in the broiler diet. These variations may be due to the quality of PKC, its sources, processing methods and value-added treatment. It has been documented that 10-15% of treated PKC could be included in the broiler’s diets. The inclusion levels will not contribute to a negative impact on the growth performances and carcass yield. Furthermore, it will not compromise intestinal microflora, morphology, nutrient digestibility, and immune system. PKC with a proper SSF process (FPKC) can be offered up to 10-15% in the diets without affecting broilers’ production performance.

A novel porous polymeric microsphere for the selective adsorption and isolation of conalbumin

Porous polymeric microspheres, poly(styrene-divinyl benzene, PSDVB)-poly(ethylene glycol monoallyl ether, PEGMAE), termed as PSDVB-PEGMAE, are prepared via double emulsion interfacial polymerization strategy. PSDVB-PEGMAE microspheres exhibit a mean diameter of 2.98 um, and possess heterogeneous porous structure with a pore volume of 0.354 cm(3) g(-1) and a pore size of 34.3 nm. PEGMAE moiety is identified on the external surface of the microspheres, while both PSDVB and PEGMAE moieties are found in the interior pores. The PSDVB-PEGMAE microspheres possess favorable selectivity towards the adsorption of conalbumin (ConA) through hydrogen-bonding and hydrophobic interactions, via surface and inter-pore adsorption. At pH 6, an adsorption capacity of 171.9 mg g(-1) is achieved for ConA. The captured ConA may be readily recovered by stripping with a cetane trimethyl ammonium bromide (CTAB) solution (0.1%, m/v). The microspheres are further used for the isolation of ConA from egg white, deriving high purity ConA as demonstrated by SDS-PAGE assay. (C) 2020 Elsevier B.V. All rights reserved.
