Enhancement of efficiency and stability in organic solar cells by employing MoS2 transport layer, graphene electrode, and graphene quantum dots-added active layer

For enhancing efficiency and flexibility of organic solar cells, new constituent materials are highly required. Here, we first report flexible organic solar cells (FOSCs) by employing MoS2 hole transport layer (HTL), bis (trifluoromethanesulfonyl)-amide-doped graphene (TFSA-GR) transparent conductive electrode (TCE), and GR quantum dots (GQDs)-added active layer. Power conversion efficiency (PCE) of the FOSCs without GQDs strongly depends on number of layers (Ln) of MoS2 as well as on doping concentration (nD) of TFSA-GR, thereby showing maximum PCE of 3.56% at L-n = 2 and n(D) = 20 mM, resulting from the lowest resistance at the TCE/MoS2/active layer interfaces. The long-term stability of the FOSCs is almost two times better than that of their counterparts with conventional organic HTL. By adding GQDs in the active layer, the PCE is further enhanced to 4.23% and is maintained at 89/82% of the original value after inner/outer repeated bending tests for 1000 cycles, respectively, indicating outstanding mechanical stability. These results suggest that GQDs are very useful for the active layer of FOSCs with better PCE and flexibility.

Impact of Circulating N-Acylethanolamine Levels with Clinical and Laboratory End Points in Hemodialysis Patients

Background: Patients with ESRD on maintenance hemodialysis (MHD) are particularly susceptible to dysregulation of energy metabolism, which may manifest as protein energy wasting and cachexia. In recent years, the endocannabinoid system has been shown to play an important role in energy metabolism with potential relevance in ESRD. N-acylethanolamines are a class of fatty acid amides which include the major endocannabinoid ligand, anandamide, and the endogenous peroxisome proliferator-activated receptor-alpha agonists, oleoylethanolamide (OEA) and palmitoylethanolamide (PEA). Methods: Serum concentrations of OEA and PEA were measured in MHD patients and their correlations with various clinical/laboratory indices were examined. Secondarily, we evaluated the association of circulating PEA and OEA levels with 12-month all-cause mortality. Results: Both serum OEA and PEA levels positively correlated with high-density lipoprotein-cholesterol levels and negatively correlated with body fat and body anthropometric measures. Serum OEA levels correlated positively with serum interleukin-6 (IL-6) (rho = 0.19; p = 0.004). Serum PEA and IL-6 showed a similar but nonsignificant trend (rho = 0.12; p = 0.07). Restricted cubic spline analyses showed that increasing serum OEA and PEA both trended toward higher mortality risk, and these associations were statistically significant for PEA (PEA >= 4.7 pmol/mL; reference: PEA <4.7 pmol/mL) after adjustments in a Cox model (hazard ratio 2.99; 95% confidence interval 1.04, 8.64). Conclusions: In MHD patients, OEA and PEA are significantly correlated with variables related to lipid metabolism and body mass. Additionally, higher serum levels of PEA are associated with mortality risk. Future studies are needed to examine the potential mechanisms responsible for these findings and their clinical implications. I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 3493-12-7 help many people in the next few years. Category: amides-buliding-blocks.

Chemoenzymatic Method for Enantioselective Synthesis of (R)-2-Phenylglycine and (R)-2-Phenylglycine Amide from Benzaldehyde and KCN Using Difference of Enzyme Affinity to the Enantiomers

In general, enzymatic and chemoenzymatic methods for asymmetric synthesis of alpha-amino acids are performed using highly enantioselective enzymes. The enzymatic reactions using alpha-aminonitrile as a starting material have been performed using reaction conditions apart from the chemical Strecker synthesis. We developed a new chemoenzymatic method for the asymmetric synthesis of alpha-amino acids from aldehydes and KCN by performing Strecker synthesis and nitrilase reaction in the same reaction mixture. Nitrilase AY487533 that showed rather low enantioselectivity in hydrolysis of 2-phenylglycinonitrile (2PGN) to 2-phenylglycine (2PG) was utilized in the hydrolysis of aminonitrile formed from benzaldehyde and KCN via 2PGN by Strecker synthesis, preferentially synthesizing (R)-2PG with more than 95 % yield and enantiomeric excess (ee). The method was also utilized for the synthesis of (R)-2-phenylglycine amide ((R)-2PGNH(2)) from benzaldehyde and KCN by the chemoenzymatic reaction in the presence of a mutated nitrilase AY487533W186A, which catalyzes the conversion of 2PGN to 2PGNH(2).

Effect of Spacer Length between Phenyl Pendant and Backbone in Comb Copolymers on Flow Ability of Waxy Oil with Asphaltenes

Waxy crude oil containing large amounts of paraffins often results in various difficulties in extraction and transportation, especially at low temperature. Comb-type copolymers with phenyl pendants were found to be able to improve the flow ability of waxy oils effectively. To investigate the influence of spacer length between phenyl pendant and polymer backbone in comb copolymers on the flow ability of waxy oil, poly(alpha-octadecene-co-maleic acid phenyl alkyl amide)s with various spacer lengths were synthesized by modification of poly(alpha-octadecene-co-maleic anhydride) with aniline, phenethylamine, phentermine, and phenyl-undecanoicamide. Their effects on the morphology and crystallization of model and crude oils were observed by polarized light microscopy and DSC. The flow ability of both oils in the presence of copolymers was studied by means of rheology, including measuring yield stress, viscosity, and thixotropic properties. It is found that the spacer length remarkably affects the rheology and wax crystallization behaviors for both oils. The copolymer with a longer spacer can provide better flexibility of phenyl pendants to disperse asphaltenes more effectively, and the long spacer can cocrystallize with long-chain paraffins.

Arbuscular mycorrhizal fungi mitigate drought stress in citrus by modulating root microenvironment

This study aimed to evaluate effects of Funneliformis mosseae on plant growth and root exudate compositions and contents, soil and root phosphatase activity, soil glomalin concentrations, and thus soil aggregate stability and distribution in trifoliate orange under well-watered (75% of maximum water holding capacity) and drought stress (55% of maximum water holding capacity) conditions. After eight weeks of drought treatment, mycorrhizal fungal inoculation improved plant growth and exhibited altered composition of root exudates than non-inoculated treatment. Mycorrhizal fungal inoculation dramatically increased the relative abundance of phenolics (e.g., 2 H,8 H-Benzo[1,2-b:3,4-b’] dipyran-2-one,8,8-dimethyl), terpenoids (e.g., geijerene), and acids (n-hexadecanoic acid), while notably reduced the relative abundance of alkanes (e.g., tridecane, 2-methyl-), esters (e.g., hexanedioic acid and dimethyl ester), and amides (e.g.,13-docosenamide) in root exudates. Mycorrhizal fungal colonization profoundly increased easily extractable and total glomalin-related soil protein levels under two soil water regimes, which cemented soil macroaggregate (2-4 mm size) formation, thereby, improving soil aggregate stability. Mycorrhizal fungal-inoculated plants represented higher soil acid, alkaline and total phosphatase activities, irrespective of well-watered and drought treatment. The results suggest that mycorrhizal plants had improved root microenvironment to mitigate drought damage through changes in root exudate components along with glomalin, phosphatase, and soil aggregate stability in the mycorrhizosphere.

pH-Driven Wetting Switchability of Electrodeposited Superhydrophobic Copolymers of Pyrene Bearing Acid Functions and Fluorinated Chains

A smart stimuli-responsive surface was fabricated by the electro-copolymerization of pyrene monomers followed by base and acid treatment. Copolymers of pyrenes bearing fluorinated chains (Py-nF(6)) and acid functions (Py-COOH) were produced with different molar concentrations of each monomer (0, 25, 50, 75, and 100% of Py-nF(6) vs. Py-COOH) by an electrochemical process. Two different perfluorinated pyrenes containing ester and amide groups were used to reach superhydrophobic properties. The relation of those bonds with the final properties of the surface was explored. The pH-sensitive group of Py-COOH allowed the surfaces to be reversibly switched from superhydrophobic (water contact angle>(w)>150 degrees and very low hysteresis) to hydrophilic ((w)<90 degrees). The amide and ester bonds influenced the recovery of the original wettability after both base and acid treatment. Although the fluorinated homopolymer with ester bonds was insensitive to base and acid treatment due to its superhydrophobic properties with ultralow water adhesion, the recovery of the original wettability for the copolymers was much more important with amide bonds due to the amide functional groups be more resistant to the hydrolysis reaction. This strategy offered the opportunity to access superhydrophobic films with switchable wettability by simple pH treatment. The films proved to be a good tool for use in biological applications, for example, as a bacterial-resistant film if superhydrophobic and as a bacterial-adherent film if hydrophilic.

Both modular and single-domain Type I polyketide synthases are expressed in the brevetoxin-producing dinoflagellate, Karenia brevis (Dinophyceae)

Dinoflagellates are prolific producers of polyketide compounds, many of which are potent toxins with adverse impacts on human and marine animal health. To identify polyketide synthase (PKS) genes in the brevetoxin-producing dinoflagellate, Karenia brevis, we assembled a transcriptome from 595 million Illumina reads, sampled under different growth conditions. The assembly included 125,687 transcripts greater than 300 nt in length, with over half having >100x coverage. We found 121 transcripts encoding Type I ketosynthase (KS) domains, of which 99 encoded single KS domains, while 22 contained multiple KS domains arranged in 1-3 protein modules. Phylogenetic analysis placed all single domain and a majority of multidomain KSs within a monophyletic clade of protist PKSs. In contrast with the highly amplified single-domain KSs, only eight single-domain ketoreductase transcripts were found in the assembly, suggesting that they are more evolutionarily conserved. The multidomain PKSs were dominated by trans-acyltransferase architectures, which were recently shown to be prevalent in other algal protists. Karenia brevis also expressed several hybrid nonribosomal peptide synthetase (NRPS)/PKS sequences, including a burA-like sequence previously reported in a wide variety of dinoflagellates. This contrasts with a similarly deep transcriptome of Gambierdiscus polynesiensis, which lacked NRPS/PKS other than the burA-like transcript, and may reflect the presence of amide-containing polyketides in K.brevis and their absence from G.polynesiensis. In concert with other recent transcriptome analyses, this study provides evidence for both single domain and multidomain PKSs in the synthesis of polyketide compounds in dinoflagellates.

Removal of toxic heavy metals, phenolic compounds and textile dyes from industrial waste water using phosphonium based ionic liquids

This article focused on a comprehensive result of the development of three phosphonium based room temperature ionic liquids (RTILs) of same cation, trihexyltetradecylphosphonium ([PC6C6C6C14]), with different organic or inorganic anions viz. [Cl-] chloride dicyanamide [-N(CN)(2)(-)] and bis (trifluoromethyl sulfonyl) amide [-NTf2-] in extraction processes of toxic textile dyes as rhodamine B, methylene blue, methyl orange, malachite green, alizarin red S and congo red dyes from their aqueous solution, harmful heavy metals include As, Cr, Cd, Cu, Zn, Pb and Hg from their standard solutions AS(NO3)(3), Cr(NO3)(3), Cd(NO3)(2), Hg(NO3)(2), Pb(NO3)(2), Zn(NO3)(2) & Cu (NO3)(2) respectively and phenolic compounds from rice and cashew industrial waste water. In technological front, ILs revealed a potential ability for the removal of dyes, heavy metals and phenolic compounds owing to their hydrophobic nature on investigating via liquid -liquid extraction method. The effect of contact time, solution pH and initial concentration of dyes were investigated and the result show that adsorption of dyes increases with increasing contact time and gets maximum decolourisation at acidic pH and pH 7. The extraction process of heavy metals with the ILs were investigated and were assessed using the techniques UV-Visible spectroscopy and ICP-MS (Inductive Coupled Plasma Mass Spectroscopy). The three ILs showed best extraction efficiency (approx. 100%) for all heavy metals and the dyes using proposed methodology. UV-Visible Spectroscopy quantification method was employed to analyse extracted phenolic compounds. Screening results of phenolic compounds have shown that [PC6C6C6C14][Cl] IL exhibited the capacity intake of 100% efficiency from rice and cashew industrial waste water. The Its were characterized with thermogravimetry (TGA) and from which, the samples showed a good thermal stability up to 573 K to project them as promising one for high temperature needs in various technological fronts. Toxicity risks of the three ILs and the textile dyes used were examined by in silico OSIRIS software calculations and the ILs were found to be non-toxic. (C) 2020 Elsevier B.V. All rights reserved.

Biosorption isotherm study of Cd2+ Pb2+ and Zn2+ biosorption onto marine bacterium Pseudoalteromonas sp SCSE709-6 in multiple systems

To overcome the low efficiency and prerequisites conditions of simultaneous metals removal and the unsuitability of single metal adsorption isotherm models in multiple metals, the multiple biosorption of Cd2+, Pb2+ and Zn2+ onto a new marine Pseudoalteromonas sp. SCSE709-6 from aqueous solution was studied and compared with single metal system. Results showed that Pseudoalteromonas sp. SCSE709-6 was a competitive biosorbent for metals from aqueous solutions in single system (maximum adsorption capacity: 138 mmol g(-1) for Cd2+, 1.05 mmol g(-1) for Pb2+ and 0.91 mmol g(-1) for Zn2+, respectively). The affinity between metals and biosorbent calculated by the separation factor in binary metals systems followed the order: Pb2+ > Cd2+ > Zn2+. In multiple metals systems, Cd2+ biosorption was the most sensitive, while Pb2+ biosorption was the least sensitive. In addition, Pb2+ biosorption had less pH dependence than the biosorption of Cd2+ and Zn-2. Among six isotherm models applied in this study, the extended Freundlich isotherm model best described the binary metal biosorption behaviors. Isotherm analysis revealed that binary biosorption was a complex process which occurred both mono- and multi-layer biosorption. FT-IR result spectrum revealed that carboxyl, amide, acyl and hydroxyl played a significant role in metals biosorption. This study showed superior performance of metal removal by Pseudoalteromonas sp. SCSE709-6 in multiple metals systems. (C) 2017 Elsevier B.V. All rights reserved.
