Study on the evolution characteristic of intermediate during the pyrolysis of oil shale

The pyrolysis of oil shale is a complex process including a myriad of chemical reactions. A widely approved understanding suggests a two-step decomposition process for oil shale pyrolysis, considering bitumen as the intermediate product. In this study, intermediates derived from various pyrolysis conditions are comprehensively studied by FTIR, GC, GC-MS and NMR methods to understand the pyrolysis mechanism of oil shale and composition feature of intermediate. The pyrolysis of oil shale is a dynamic process, and the results show that the intermediate is continuously generated before 400 A degrees C, accompanying with the formation of final products from both intermediate and kerogen. The maximum yield of intermediates is presented at the fastest oil-producing temperature range (375 A degrees C in this study). Carbon chains in intermediate become short with the increase in temperature. Most components in pyrolysis intermediate are long straight aliphatic chains; thus, intermediate is much heavier than shale oil. Further reactions make intermediate convert into shale oil product. Aliphatic hydrocarbons occupied the biggest proportion over 86% at 375 A degrees C, mainly in the form of straight-chain alkanes. A few parts of aromatic fragments with small ring numbers will also transfer into intermediate. The heteroatom-containing compounds are mainly alcohols, ketones, amides and halohydrocarbons. High aromaticity in shale oil at high temperatures can be attributed to the condensation reaction of abundant aliphatic hydrocarbons in intermediate. During the conversion process from intermediate to final products, the generating capacity of oil is evidently higher than that of gas.

Carbon input manipulations affecting microbial carbon metabolism in temperate forest soils – A comparative study between broadleaf and coniferous plantations

Large uncertainties exist about the relative importance of aboveground litter and root carbon input on soil organic carbon decomposition in different forest types. Here, we report on our detritus input and removal treatments conducted to investigate how changes in aboveground and belowground carbon inputs affect soil organic carbon content and various microbial carbon metabolic functions in different plantation types (oak vs. pine, broadleaf vs. coniferous). The results of our study showed that doubling aboveground litter significantly increased SOC content and labile carbon metabolism in the oak plantation but not the pine plantation. Root trenching and aboveground litter removal decreased SOC content and carbon metabolisms. The effect of root trenching on carbon metabolisms was weaker than litter removal in the oak plantation but not the pine plantation. Detritus input and removal treatments changed the diversity and function of labile carbon (starch, carbohydrates, and amines/amides) and the metabolic activity of soil microorganisms in oak plantation, but mainly influenced recalcitrant carbon (polymers) metabolism in the pine plantation. Detritus input and removal treatments influenced the composition of microbial carbon metabolic genes and functions mainly by modifying the soil environment and nutrient availability including moisture, pH, nitrate content, and available phosphorus content in the oak plantation, while it influenced carbon metabolism by altering soil moisture, and the ammonium, nitrate, and organic carbon content in the pine plantation. These findings indicate that different forest ecosystems could respond differently to different disturbances, and forest management should be adjusted accordingly.

Mixed-ligand complexes of tenoxicam drug with some transition metal ions in presence of 2,2 ‘-bipyridine: Synthesis, spectroscopic characterization, thermal analysis, density functional theory and in vitro cytotoxic activity

The Preparation and characterization of Cr(III), Fe(III), Co(II), Ni(II), Cu(II) and Y(III) mixed ligand metal complexes with the effective anti-inflammatory drug tenoxicam (Ten) and 2,2’-bipyridine (Bipy) have been informed in this study by using elemental analyses, FT-IR, UV-Vis., H-1 NMR, mass spectra, thermal analyses (TGA, DTG), molar conductance and magnetic moment. FT-IR and UV-Vis. spectra proved that Ten acts as a neutral bidentate ligand chelated to the metal ions via the pyridine-N and oxygen of carbonyl group of the amide moiety and Bipy chelated through the nitrogen atoms. The thermodynamic parameters (E*, Delta S*, Delta H* and Delta G*) were calculated by using Coats-Redfern and Horowitz- Metzger method from DTG curves. The antimicrobial activity for all compounds against various species of bacteria and fungi was investigated and the results ensured that Fe(III) complex is more active than all other complexes. The DFT calculations were carried out to understand the optimized molecular geometry for the compounds. All studied complexes considered as soft respect to the Ten, with G value varied from 11.236 to 16.949 eV and equal to 8.772eV for Ten. The anticancer activity was screened against cell culture of HCT-116 (human colorectal carcinoma), HepG2 (human hepatocellular carcinoma) and MCF-7 (human breast adenocarcinoma) for all compounds.

Effects of High Hydrostatic Pressure assisted degreasing on the technological properties of insect powders obtained from Acheta domesticus & Tenebrio molitor

In this study, two edible insect species; Acheta domesticus (house cricket) and Tenebrio molitor (yellow mealworm) were defatted using different extraction methods and characterized afterwards. The main goal of the study was to see the effect of High Hydrostatic Pressure (HHP) extraction at different temperatures on the functional properties of the insect powders. Protein content, solubility, water and oil binding capacity; total phenolic content and antioxidant activity were all effected from the extraction method. Results showed that, temperature increase from 30 to 40 degrees C caused a decrease in the protein solubility of both powders. NMR relaxometry was used to interpret the gelation behavior and FTIR spectroscopy showed absorbance peaks mainly in amide I, amide II and amide III regions for both species. Results confirmed that HHP can be used for defatting purposes and could improve the functional properties of the powders to be used as a food additive in formulations.

Lightweight, flexible and highly sensitive segregated microcellular nanocomposite piezoresistive sensors for human motion detection

Lightweight, flexible and highly sensitive piezoresistive sensors are promising for future generations of wearable electronics, artificial intelligence, human-computer interaction and soft robotics. Herein, segregated micro-cellular nanocomposites based on the microcellular poly(ether-block-amide) beads coated with silver (microcellular Pebax@Ag beads) are fabricated by the scalable and feasible supercritical CO2 foaming combined with dip-coating and curing approach. The segregated microcellular nanocomposites show low mass density (0.6 g/cm(3)), good flexibility (60% compressibility) and high electrical conductivity (0.64 S/m) with ultralow percolation threshold (0.28 vol%) benefiting from the simultaneous incorporation of segregated structures and microcellular structures. The resultant segregated microcellular nanocomposite piezoresistive sensors exhibit superior piezoresistive performances including improved relative resistance changes and higher sensitivity upon the externally applied compression strains owing to the synergistic effect of multiple mechanisms: higher local effective MWCNT contents due to the excluded-volume effect, construction of more effective 3D MWCNT/Ag conductive networks and rapid response due to the highly-resilient microcellular Pebax beads. Furthermore, the segregated microcellular nanocomposite piezoresistive sensors show outstanding long-term durability and working stability upon the repeated compression strains. Practical applications of the segregated microcellular nanocomposite piezoresistive sensors in functional sole materials have been verified for human motion detection during walking, implying their outstanding potential for burgeoning applications such as wearable electronics, artificial intelligence, human-computer interaction and soft robotics.

Bioactivity-guided isolation of alkamides from a cytotoxic fraction of the ethyl acetate extract of Anacyclus pyrethrum (L.) DC. roots.

Introduction. The alcohol extract of Pellitory (Anacyclus pyrethrum) roots has been previously shown to exert anticancer activities on the Human Colorectal Cancer Cell Line (HCT) by targeting apoptosis, metastasis and cell cycle arrest. However, the nature of the cytotoxic molecules associated with this activity remains unexplored. Aims. This study aims to reinvestigate Pellitory root extract as regard to its cytotoxic activity and to proceed to a bioguided fractionation to explore its active fraction and to give new insight in their phytochemical constituents. Methods. Powdered roots were subjected to repeated extraction with Petroleum ether (Pe), Chloroform (Ch), Ethyl acetate (Ea) and Methanol (Me). Pellitory extracts were then screened for cytotoxic activity using the Brine Shrimp Lethality (BSL) bioassay. Results. Ea extract exhibited a marked cytotoxic activity, with LC50 of 249.26 mu g/mL in the BSL bioassay. The remaining extracts (Pe, Ch, Me) treated groups exhibited no or low mortality in the range of tested concentrations (1-1000 mu g/mL). BSL assay-guided chromatographic fractionation of Ea active Extract revealed a highly cytotoxic fraction (F11) with LC50 of 42.5 mu g/mL. Multistep purifications of the active F11 fraction afforded four alkamides, namely N-isobutyldeca-2,4-dienamide or Pellitorine (I), N-propyldodeca-2,8-dienamide (II), N-isobutyltetradeca-2,4-dienamide (III) and N-propylnona-2,5-dienamide (IV). Conclusions. This study suggests that cytotoxic activity is localized mainly in the ethyl acetate extract (Ea) of pellitory roots. BSL assay fractionation of this active extract leads to the isolation of four alkamides, including pellitorine (I). While this isobutyl alkamide has previously shown strong cytotoxic activities against human cancer cell lines, the other compounds (II to IV) were not previously reported as cytotoxic. Subsequently, the isolated alkamides will be considered in future study as candidates for in depth in-vitro evaluation of their cytotoxicity against cancer and normal cell lines. Finally, through this study, BSL assay demonstrate again its usefulness as bench-top assay in exploring plant extracts for cytotoxic compounds.

Antiproliferative effect, alteration of cancer cell cycle progression and potential MET kinase inhibition induced by 3,4-dihydropyrimidin-2 (1H)-one C5 amide derivatives

Cancer continues to be the second leading cause of death worldwide. Discovery of novel therapeutic agents has crucial importance for improvement of our medical management capabilities. Dysregulation of the MET receptor tyrosine kinase pathway plays an important role in cancer progression, making this receptor an attractive molecular target for anticancer drug discovery. In this study, twenty-seven 3,4-dihydropyrimidin-2(1H)-one C5 amide derivatives were synthesized and their cancer cell growth inhibitory activity was examined against MCF-7, HT-29 and MOLT-4 cells and also NIH/3T3 non-cancer cells by MTT assay. The antipmliferative effect of the most potent derivatives were tested against MET-dependent EBC-1 and MKN-45, lung and gastric cancer cell lines, respectively. MET kinase inhibition was measured by a Homogenous Time Resolved Fluorescence (HTRF) Assay. The influence of the test compounds on cell cycle was examined by RNase/PI flow cytometric assay. A number of compounds exhibited considerable antiproliferative effects against breast and colon cancer and leukemia cell lines, relatively sparing non-cancer cells. Some derivatives bearing benzothiazolyl carboxamide moiety at C5 position (15, 21, 23, 31, and 37) showed the highest activities with IC50 values as low as 10.9 mu M. These compounds showed antiproliferative effects also against MET-amplified cells and dose-dependently inhibited MET kinase activity. They also induced G0/G1 cell cycle arrest at lower doses and apoptosis at higher doses. Molecular docking and dynamics simulation studies confirmed the interaction of compound 23 with the active site of the MET receptor. These findings demonstrate that 3,4-dihydropyrimidin-2(1H)-one analogues may represent promising targeted anticancer agents.
