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.

Use of topical sevoflurane in pressure ulcer treatment in a double-lung transplant patient

Pain caused by wounds of different etiology is usually treated with oral analgesics. New topical use of products such as the ether anesthetic sevoflurane shows good results for pain control and has additional benefits. Pressure ulcers are painful and patients may benefit from the use of sevoflurane. We present the case of a double-lung transplant patient with a long-standing sacral pressure ulcer with poor pain control, for which sevoflurane dressings were used. The number of pain-free hours after application, the amount of daily analgesics and the size of the wound were monitored with the mobile wound application MOWA. After several days of sevoflurane application, the patient reduced analgesic consumption, remained longer free of pain, and the size of the wound decreased. Unfortunately, the patient had serious complications due to multiple comorbidities and died before the wound healed completely. Topical use of sevoflurane in pressure ulcers may be a good option to treat pain and improve patient quality of life.

Vegetable fixed oils obtained from soursop agro-industrial waste: Extraction, characterization and preliminary evaluation of the functionality as pharmaceutical ingredients

This study was designed to evaluate the feasibility of using oils extracted from seeds of soursop industrial waste for use as pharmaceutical ingredients. For that, soursop seeds were subjected to different processes of extraction of fixed oil, by chemical and mechanical routes. After characterization of fixed oils, the feasibility of using them as pharmaceutical excipients was explored by preparing creams in which the oils were used as emollient and/or antioxidant excipient. The oil extracted from soursop seeds in a Soxhlet device and ethyl ether solvent (SFO) showed a yield of 30.72 +/- 0.09 % (w w(-1)) and, in a domestic extruder (MFO), 23.86 +/- 0.78 % (w w(-1)). These oils showed physicochemical attributes that indicative of good preservation. The major fatty acid was the oleic acid, with 42.94-43.73 % in relative area, followed by linoleic with 29.5%-30% in relative area. In the non-grease fraction, the SFO showed considerable levels of phenolics (194.5 +/- 31.1 mg kg(-1)) and tocopherols (608.2 +/- 36.7 mg kg(-1)), which gave it an antioxidant potential, confirmed by the 2,2-diphenyl-1-picrylhydrazyl test, with a concentration effective for 50% inhibition (IC50) of 2.8 mg mL(-1). Finally, the evaluation of the quality parameters of the creams, suggests that the use of fixed soursop oils to replace the synthetic ingredients usually incorporated (decyl oleate, liquid petrolatum and butylhydroxytoluene), originated formulations with adequate physical and chemical stability. These findings suggest that both oils obtained are possible candidates for use as emollients and antioxidant in pharmaceutical formulas. In addition, contributing to minimize the generation of waste from the fruit agribusiness and add economic value to a by-product generated in the production of fruit pulp. (C) 2021 Elsevier B.V.

Synthesis, structure and property of two D-f heteronuclear Eu-TM (TM = Zn and Cd) complexes with open-chain ether Schiff base ligand

Two heteronuclear Zn-Eu and Cd-Eu complexes with open-chain ether Schiff base ligand (bis(5-bromine-3-methoxysalicylidene)-3-oxapentane-1,5-diamine (H2L) and isonicotinate (IN), with composition [ Zn2EuL2(OAc)(IN)](NO3)center dot(CH2Cl2) (1) and ([CdEuL(IN)(OAc)(NO3)(CH3OH)]center dot 3(CH2Cl2)}(n) (2), have been synthesized and characterized. The structure analysis reveals that the Zn-Eu complex is heterotrinuclear cluster and lanthanide ion acts as a joint bridging of two Zn-L coordination units, whereas the Cd-Eu complex is infinite 1D zigzag coordination polymer formed by Cd-Eu-L secondary units through bridging of isonicotinate. Fluorescence properties of complexes 1-2 in the solid state and DMF solution at room temperature were studied. It has been found that the emission spectra of complexes 1-2 do not exhibit corresponding Eu-III ion characteristic emission bands and the fluorescence properties of complexes 1-2 are different due to the introduction of different transition metal ions. Antioxidant properties of the ligand and complexes 1-2 were also studied, the results showed that the ligand and complexes 1-2 display high scavenging activity against hydroxyl (OH center dot) and superoxide (O-2(-)center dot) radicals, and the order of the activity is complex 2 > complex 1 > H2L. Therefore, the structures and properties of D-f heteronuclear complexes can be adjusted by selecting different transition metal ions such as Zn-II and Cd-II ions. (C) 2020 Elsevier B.V.

Influence of diethyl ether on engine performance and emissions characteristics of blends of butanol, pentanol or biodiesel (neem oil methyl ester) in a single cylinder diesel engine

Biodiesel has become a promising alternative biofuel that exhibits problems like high cost of feedstock, poor atomisation due to high viscosity, stability issues, poor flow properties and high NOx emissions as compared to conventional diesel. Alcohols have recently drawn much attention as a low cost biofuel that, exhibit problems like low cetane number and miscibility issues. Addition of fuel additives, for example, diethyl ether (DEE), may be effective to overcome the problems with biodiesel or alcohols. In this work, the influence of DEE on engine performance and emissions were investigated for diesel/biodiesel blends, diesel/butanol blends or diesel/pentanol blends. Fuel blends of biodiesel (B20), butanol (BU20), pentanol (PN20), biodiesel with DEE (B20D10), butanol with DEE (BU20D10) and pentanol with DEE (PN20D10) were prepared. Experiments were conducted on a single cylinder diesel engine for varying load conditions at constant speed. Engine performance and emission characteristics were determined and compared.

High-temperature oxidation of propanol isomers in the mixtures with N2O at high Ar dilution conditions

This work provides, for the first time, new information regarding the kinetics interaction between N2O and propyl alcohol isomers. To this end, the formation and consumption of atomic oxygen were measured behind the reflected shock waves using Atomic Resonance Absorption Spectroscopy (ARAS) technique for 1-10 ppm n- i- propanol + 10 ppm N2O + Ar mixtures, at 2-3 bar and over a wide temperature range of 1700-3200 K. The Konnov and POLIMI detailed combustion mechanisms were assessed against experimental data and also employed to study the main reactions influencing the oxidation dynamics of fuel mixtures under the investigated conditions. The study highlighted a certain difficulty by the models tested in predicting the formation of atomic oxygen at T < 2000 K. The rate of production and the sensitivity analysis was performed with the attempt to identify the most important reactions involved in the process oxidation for future kinetic model refinements.

Hydroconversion of Kraft lignin for biofuels production using bifunctional rhenium-molybdenum supported zeolitic imidazolate framework nanocatalyst

Non-noble bimetallic nanoparticles anchored on Zeolitic Imidazolate Frameworks, bifunctional ReMo@ZNB catalyst, has been demonstrated to promote Kraft lignin depolymerization. In this study, the catalytic activities under different heat treatment conditions are ranked as follows: ReMo@ZNB-700 (Air) > ReMo@ZNB-500 (Air) > ReMo@ZNB-700 (N-2). Particularly, bimetallic ReMo nanocatalyst with Re/Mo atomic ratio of 1/3 shows superior performance. Excellent yields of Ethyl acetate soluble products (92.18%) and Petroleum ether extracted biofuels (78%) are obtained at 300 degrees C and 24 h, and the calorific value is 32.33 MJ/kg. The ReMo@ZNB catalyst exhibits superior recyclability and regeneration after cycle experiment. Structural characterization results reveal that the incorporation of ReMo can engender the transformation of lattice morphology, the strength of hydrogenation and acid adsorption. The possible mechanism is based on the synergism of adsorption coupling and hydrogenation over ReMo@ZNB catalyst. The synergic action initiates potential perspectives for improving lignin hydroconversion.

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.

One-step sustainable synthesis of cationic high-swelling polymers obtained from starch-derived maltodextrins

The good water solubility displayed by most starch-derived maltodextrins has limited their use when specific mechanical properties are required, particularly when working in aqueous media. As a result, numerous attempts to cross-link such polysaccharides to obtain cross-linked polymers have been reported; in this context, non-toxic and biocompatible water-soluble diglycidyl ethers have performed well. Besides, amines are commonly used as curing agents in combination with diglycidyl ethers for the production of epoxy resins. For this reason, amine-mediated epoxy ring-opening reactions of 1,4-butanediol diglycidyl ether have been studied as approaches to obtain sustainable cross-linked polymers suitable for eco-friendly scaling-up, based upon commercial starch-derived maltodextrins, using water as a unique solvent.
