Concentrations, sulfur isotopic compositions and origin of organosulfur compounds in pore waters of a highly polluted raised peatland

Sulfur cycling in peatlands plays a key role in their response to atmospheric deposition of acid sulfate; however, the role of dissolved organic sulfur species has received little attention. In this study, we assess the quantitative importance of dissolved organic sulfur species in a heavily polluted peatland and their role in sulfur cycling. Surface and pore waters from a raised peat bog have been analyzed for dissolved organic and inorganic species. Except in the surface water, organically bound sulfur dominates over sulfate sulfur and the organosulfur is predominantly in the humic fraction, which is not GC amenable. Two organosulfur compounds are present in the GC amenable fraction at all depths; a compound containing a benzene ring, sulfone and amide groups dominates while a compound closely similar to either benzothiazole or 1,2-benzisothiazole is present at 100-1000 times lower concentrations. Other organosulfur species were detected in some samples by GC-AED (gas chromatography-atomic emission detection) at similar or yet lower concentrations but not identifiable with GC-MS. In the shallowest parts of the peat, sulfur isotopic data on the humic and non-humic dissolved organic sulfur fractions show a pronounced difference, implying different sources for these organosulfur compounds. Humic organosulfur is 34S enriched, indicating a source for this component from breakdown of plant materials, which have similar delta34S (0.1? and 4.2?). By contrast, the non-humic organosulfur is more 34S depleted at shallow depths (-11.7? in surface water), indicating an origin from reaction of bacterially produced sulfide (-9.9? in surface water) with dissolved organic material. Deeper in the peat the non-humic organosulfur becomes more 34S enriched (up to +6.8?), which may result from either: (i) reactions between organic material and more 34S enriched sulfide; or (less likely) (ii) a shift to production of non-humic organosulfur by breakdown of humic compounds or plant material in the peat matrix. These data highlight the importance of organosulfur species relative to inorganic species in peatland groundwaters. Organosulfur species comprise the bulk of the dissolved sulfur budget and are involved in the bacterial cycling of sulfur in the peatland ecosystem.

Microwave pyrolysis of tire powders: Evolution of yields and composition of products

The evolution of products of tire powders, with special attention to the yields and composition over time under microwave pyrolysis, was studied. The solid, liquid, and gaseous products generated were all collected separately during the pyrolysis process and characterized. In addition, temperature was measured using a thin thermocouple intermittently. The sample temperature first rose, then fell, and finally stabilized at approximately 500?C. The major components of the pyrolysis gases were H2, CH4, and C2H4. The liquid products were complex mixtures of organic compounds with large proportions of aromatics and limonene. The solid residues, with high contents of carbon black and S, pyrolyzed almost completely at 20?min, and the samples in the center of the reactor were pyrolyzed earlier than those in the surrounding areas were. At the end of the pyrolysis, 43% of the solid residues, 45% of the oils, and 12% of the pyrolysis gases were obtained.

Investigating the differences of flavor profiles between two types of soy sauce by heat-treatment

The difference of flavor profiles and physicochemical properties between the two types of raw soy sauces and heated soy sauces were investigated in the present research. The results indicated that no significant changes of physicochemical properties, organic acids (except succinic acid) or CIELAB color space among the samples after heat-treatment were observed. However, the content of volatiles was increased by about 30.89% in the fortified sample (PP1) by heat-treatment. The contents of 26 and 15 constituents in PP1 and PP2 (natural fermented sample) were enhanced compared with their respective control (P1 and P2), respectively. According to the changes of the constituents with odor activity value (OAV), the contribution of heat-treatment on soy sauce flavor profiles was related closely to the raw soy sauce type. The spicy, caramel-like and fruity note of heated soy sauces were higher than that of raw soy sauces, and the increasements of spicy, caramel-like and fruity note of PP1 were higher than that of PP2. These results may contribute to optimizing the heat-treatment parameters and improve the flavor of soy sauce.

Release of volatile organic compounds by oxidative wear of automotive friction materials

Contribution of friction processes to the environmental pollution was proven in several studies, especially with respect to release of particulate emissions containing metals. Not too many researchers pay attention to volatile organic compounds formation during braking, although it is very relevant topic. When organic friction materials are used, the oxidative processes and thermal degradation always accompanies the friction processes during braking. A low-metallic, brake lining formulation was tested using the ISO 26867 friction evaluation standard procedure in an automotive full-scale brake dynamometer. Sampling of non-airborne debris, suspended airborne particles (PM10) and air was performed directly in the environmental chamber. Released volatiles and semi volatile organics were analyzed using GC/MS, Pyr/GC/MS, FTIR and carbon phase analysis. Occurrence of important groups of volatile organic compounds as PAHs and BTEXs with possible adverse effects on living organisms was confirmed.

Tellurium-nitrogen-containing heterocycles

This chapter focuses on the tellurium-nitrogen-containing heterocycles. More than 20 diverse structural types of the heterocycles containing tellurium and nitrogen atoms in a ring have become known, most having been studied during the last decade. Both the methods for the preparation and the reactions of tellurium-nitrogen-containing heterocycles differ from those characteristic of their sulfur and selenium analogues. Owing to the higher nucleophilicity of Te (II) centers, tellurium heterocycles readily form telluronium salts and give stable complexes even with relatively soft Lewis acids. In tellurium heterocycles, Te (II) centers are capable of forming intramolecular and intermolecular coordination bonds with oxygen and nitrogen centers that are stronger than the bonds formed by other chalcogen centers. This property of organotellurium compounds is responsible for the peculiar physical characteristics of benzoisotellurazole, 1,2,5-telluradiazole, and some other tellurium-nitrogen-containing heterocycles. Heterocycles with one tellurium (Te)atom and one nitrogen (N) atom include isotellurazoles, their benzo fused derivatives, and benzotellurazoles. Derivatives of three of the four possible structural types of heterocycles with one Te atom and two N atoms have been synthesized and discussed in the chapter. The chapter also discusses heterocycles containing other elements in the ring along with Te and N atom, tellurium- and nitrogen-containing macrocycles, and tellurium-containing heterocycles with N-bridged atoms.

Optimization studies of microwave-induced co-pyrolysis of empty fruit bunches/waste truck tire using response surface methodology

The central composite design of RSM was utilised for the optimization of experimental conditions of microwave-assisted co-pyrolysis of empty fruit bunch (EFB) and waste truck-tire (TT) to maximise the co-pyrolysis oil and energy yield. The predicted maximum co-pyrolysis oil of 40.0 wt% and energy yield of 59.0% were obtained at the optimum conditions of 505 C pyrolysis temperature, 65.0% of EFB ratio and 60.0 g of activated carbon loading. The reaction temperature and TT ratio in EFB feedstock were identified as the most significant variables that affect the oil and energy yield. A design of experiment was performed to determine the quality of liquid oil. The result indicates the co-pyrolysis oil (PO65) properties were significantly improved after adding TT to EFB biomass. Olefin-rich pyrolytic oil (39.0%) with high selectivity of D-limonene was produced (28.6%). While, the oxygenates and polyaromatics hydrocarbon were reduced to 9.9% and 7.4%, respectively. The energy recovery analysis shows that the optimised co-pyrolysis oil (PO65) was 20.0% higher as compared to the TT alone. In view of the improved yield and quality of co-pyrolysis oil (PO65), this work shows that co-pyrolysis of EFB/TT presents a viable method to produce diesel-like fuel using the microwave-assisted heating method.

Characterisation of free and glycosidically bound aroma compounds of la Mancha Verdejo white wines

The aroma of Verdejo La Mancha white wines was studied by instrumental and sensory analysis across five consecutive vintages to determine their typicity and quality. Free and glycosidically-bound aroma compounds were isolated by solid phase extraction (SPE) to later be analysed using gas chromatography-mass spectrometry (GC/MS). Seventy-four (74) free aroma compounds and thirty-six (36) bound aroma compounds were identified and quantified in La Mancha Verdejo wines oven this five year period. Based on the result, Verdejo white wines presents a complex chemical profile with a wealth of aromas in its aromatic composition. The sensory profile of Verdejo wines was evaluated by experienced wine-tasters and was characterised by fresh, citric, green apple, fruity and tropical fruit aroma descriptors. This study shows the first complete aromatic characterisation of La Mancha Verdejo white wines, also the data suggest that these wines present a great aromatic potential.

Design strategies of oxidosqualene cyclase inhibitors: Targeting the sterol biosynthetic pathway

Targeting the sterol biosynthesis pathway has been explored for the development of new bioactive compounds. Among the enzymes of this pathway, oxidosqualene cyclase (OSC) which catalyzes lanosterol cyclization from 2,3-oxidosqualene has emerged as an attractive target. In this work, we reviewed the most promising OSC inhibitors from different organisms and their potential for the development of new antiparasitic, antifungal, hypocholesterolemic and anticancer drugs. Different strategies have been adopted for the discovery of new OSC inhibitors, such as structural modifications of the natural substrate or the reaction intermediates, the use of the enzyme’s structural information to discover compounds with novel chemotypes, modifications of known inhibitors and the use of molecular modeling techniques such as docking and virtual screening to search for new inhibitors. This review brings new perspectives on structural insights of OSC from different organisms and reveals the broad structural diversity of OSC inhibitors which may help evidence lead compounds for further investigations with various therapeutic applications.

Improvement of Verdejo white wines by contact with oak chips at different winemaking stages

The effect that the addition of wood at different stages of the winemaking process has on the volatile composition and sensory characteristics of Verdejo wines has been studied. Verdejo control wine was made by the traditional winemaking process without oak chips. Oak chips (7 g/L) were added at different stages of the winemaking process: during alcoholic fermentation (OCAF) and in the young wine (OCW). Higher alcohols, ethyl acetate, hexyl acetate, isoamyl acetates and ethyl esters of straight-chain fatty acids were present at higher concentrations in wines that had contact with oak chips during alcoholic fermentation when compared to control wines. The highest concentrations of benzene compounds, oak lactones and furanic compounds were found in both wines in contact with oak chips, particularly in CW samples. Different sensorial profiles were obtained for the wines depending on the stage of the winemaking process at which the chips were added. All wines investigated in this study can provide a viable alternative to traditional Verdejo wines.
