Fabrication and electrochemical property of La0.8Sr0.2MnO3 and (ZrO2)(0.92)(Y2O3)(0.08) interface for trace alcohols sensor

A mixed potential type alcohols gas sensor based on an yttrium stabilized zirconia (YSZ) electrolyte and an La0.8Sr0.2MnO3 (LSM) sensing electrode was fabricated. The influences of YSZ-LSM interface on sensing performance were studied by multiple methods including X-ray diffraction (XRD), scanning electron microscope (SEM), energy dispersive spectroscopy (EDS), thermogravimetric analysis and differential scanning calorimetry (TG-DSC) and electrochemical impendence spectroscopy (EIS). The sensor with 1150 degrees C-sintered interface showed an ultralow detection limit of 50 ppb alcohols (methanol and ethanol) at 500 degrees C in air. The response voltage was independent of water, CO, CO2 and NOx. The sensor exhibited a reasonable selectivity towards alcohols under the existence of several kinds of volatile organic compounds. Meanwhile, the sensor showed a good repeatability and a suitable long-term stability. Based on the polarization curves and EIS results, a mixed potential mechanism was proposed. These results demonstrate the promising potential of using the LSM-based sensor for human exhale test.

Oxone activation by UVA-irradiated Fe-III-NTA complex: Efficacy, radicals formation and mechanism on crotamiton degradation

This study demonstrated an efficient activation of Oxone by ultraviolet light A-irradiated Fe-III-nitrilotriacetate complex to induce the generation of sulfate and hydroxyl radicals (i.e., SO4 center dot- and HO center dot) under initial neutral pH. The important parameters such as the solution pH, the molar ratio of nitrilotriacetate:Fe-III, the dosages of Oxone and Fe-III-nitrilotriacetate complex were evaluated in terms of the degradation kinetics of an emerging contaminant Crotamiton. The results indicated that fast degradation rates of crotamiton were achieved under initial circumneutral conditions (e.g., pH 5.0-7.0), with apparent rate constants at 0.0936-0.1287 min(-1) (the ultraviolet light fluence-based rate constants at 0.48-0.66 J(-1) cm(2)). In addition, the optimal molar ratio of nitrilotriacetate:Fe-III was determined as 1:1, larger ratios decreased the degradation rate of crotamiton due to the competition effect of nitrilotriacetate on SO4 center dot-. The suitable dosages of Oxone and Fe-III-nitrilotriacetate complex were determined as 0.5 mM and 0.1 mM, respectively. Under the given optimal conditions, more than 99% degradation efficiency of crotamiton was achieved at an ultraviolet light fluence of 3.90 J cm(-2), better than those results obtained by the activation of S2O82- and H2O2. The results of quenching tests (tert-butyl alcohol and 2-propanol as scavengers) suggested that SO4 center dot- and HO center dot contributed similar to 65% and 35% to the degradation of crotamiton, respectively. Furthermore, the identified intermediates includes hydroxy-crotamiton, dihydroxy-crotamiton, aldehyde-crotamiton, aldehyde-dihydroxy-crotamiton, N-ethyl-2,3-dihydroxy-N-(o-tolyl)butanamide, (E)-N-ethyl-N-phenylbut-2-enamide, 2-(ethylamino)benzaldehyde and/or 2-(o-tolylamino)acetaldehyde, and (E)-N-ethylbut-2-enamide. The results indicated that the SO4 center dot- preferentially attacked on the amide and methyl groups of crotamiton. This work provided insight into the efficacy, radicals formation and mechanism on the activation of Oxone by ultraviolet light A-irradiated FeIII-nitrilotriacetate complex, offering an alternative approach for advanced water treatment.

Enhanced flux and fouling resistance forward osmosis membrane based on a hydrogel/MOF hybrid selective layer

Although forward osmosis (FO) technology has been widely adopted for water treatment, it still faces great challenges, including low permeability and fouling problem. Herein, a novel forward osmosis membrane was developed with a stable, uniform and defect-free polyvinyl alcohol/polydopamine coated zeolitic imidazolate framework (PVA/PDA@ZIF-8) hybrid selective layer to simultaneously enhance its transport property and fouling resistance. The prepared FO membrane exhibits improved water flux without losing the selectivity, since the PDA@ZIF-8 provide additional preferential passageway for water transporting while hinder the diffusion of salt. The optimized membrane shows a higher water flux than pristine PVA membrane (14.2 vs. 8.7 L m(-2) h(-1) in FO mode, 24.3 vs. 14.8 L m(-2) h(-1) in PRO mode) with a reasonable selectivity considering as J(s)/J(w) value (0.44 vs. 0.4 g L-1 in FO mode, 0.38 vs. 0.33 g L-1). Moreover, the dynamic fouling experiments with organic foulants (protein and polysaccharide) indicate that the prepared membrane exhibits strong antifouling property and excellent permeation recovery ability (>95.0%) due to the optimized surface property. This study opens a new avenue for treatment wastewater by developing a forward osmosis membrane based on a hydrogel/MOF hybrid selective layer. (C) 2020 Elsevier Inc. All rights reserved.

Polyoxometalate-Ionic Liquids (ILs) and Polyvinyl Alcohol/Chitosan/ILs Hydrogels for Inhibiting Bacteria Colonising Wall Paintings

Historical monuments are increasingly being threatened by unexpected microbial colonizers, leading to their subsequent deterioration. Here, two tetraalkylphosphonium polyoxometalate ionic liquids (Q14-IL and Q16-IL) were successfully synthesized, which showed excellent antibacterial activity against four bacteria colonising wall paintings. Notably, Q14-IL exhibited superior antibacterial efficacy compared to longer alkyl Q16-IL. Additionally, polyvinyl alcohol/chitosan (PVA-CS) hydrogels containing two ILs were prepared, and the morphology, thermal stability, swelling ratio and antibacterial activity were systematically evaluated. The results suggest that higher CS content resulted in more uniform micropores and increased the swelling ratio. However, fewer antibacterial ILs were released and diffused over time from the matrix. Hydrogels with 5% CS content exhibited the highest antibacterial activity, which was mainly attributed to the synergetic antibacterial activity of positively charged ammonium (-NH3+) groups of CS and quaternary phosphonium cation of ILs. This study may provide an alternative strategy for fighting against bacterial communities colonising ancient artworks.

A new approach for producing mid-ethanol fuels E30 based on low-octane hydrocarbon surrogate blends

Development of mid-ethanol fuel with an ethyl alcohol content of 20-40% (E30 fuel), which is devoid of phase instability problems and can potentially be applied to automotive technology without modifications, and it is a promising area. One of the promising ways is to develop high-octane E30 fuel based on cheap low-octane fractions, which will significantly improve the economic parameters of fuel production. This research paper investigates the influence of bioethanol at a concentration of 5-85 wt% on the change in an antiknock performance of low-octane hydrocarbon fractions, involving heavy hydrocracked naphtha and straight run hydrotreated naphtha, as well as low-octane surrogate blends of individual hydrocarbons of various groups, containing n-heptane, isooctane, toluene, p-xylene, cyclohexane, n-pentane, n-hexane, and isooctene. The results indicated that the antiknock performance of bioethanol in low-octane hydrocarbon fractions was increased in the series: olefins Computed Properties of C4H11NO.

Electrochemical impedance spectroscopy studies of gasoline oxidative stability – Attempt to devise new gasolines chemical stability index

Fuels stored in storage tanks undergo aging processes. In particular, this applies to fuels containing biocomponents. The ability to quickly assess changes taking place in fuel is more and more critical due to the growing resources of fuels stored for a long time. Moreover, it is essential for maintaining the fuel quality. The purpose of this work was to develop a method enabling determination of the stability of gasolines containing biocomponents and allowing for early warning of quality deterioration. For that, the electrochemical impedance spectroscopy (EIS) was tested as it allows for fast, easy, and continuous determination of the gasoline quality. For that, the gasoline electrical parameters were determined by the EIS before and during aging. Then those results were compared with such physico-chemical parameters that change the most quickly during aging. It has been found that selected electrical parameters derived from the impedance spectra, namely, resistance, capacitance, relaxation time, and impedance values at a given frequency decrease with the aging time linearly or exponentially. The changes of those parameters indicate the formation of polar and/or ionic products and decrease of the fuel viscosity, increasing its conductivity. Furthermore, spectral studies of the samples indicate the formation of unsaturated and aromatic hydrocarbons, as well as -OH and C=O group-containing species. These observations are corroborating well with conclusions derived from the EIS studies. Notably, the obtained results indicate the correlation between electrical parameters and critical physicochemical properties of the fuel, thus suggesting possibility of applying the electrical parameters for gasoline quality assessment.

Fermentation profiling of rice wine produced by Aspergillus oryzae KSS2 and Rhizopus oryzae KJJ39 newly isolated from Korean fermentation starter

The objective of this study was to determine the fermentation characteristics of rice wine produced by koji inoculated with Aspergillus oryzae KSS2 and Rhizopus oryzae KJJ39 on moisturized wheat-bran and rice grain. We also compared rice wine samples produced in this study and three commercial Makgeolli. The alcohol content was about 12% higher in the rice wine samples fermented by wheat-bran koji than in the other samples. In all of the samples, the range of pH value was 3.8-4.6 and the total acid was below 0.5. The soluble solid content was highest in the rice wine sample prepared by the wheat-bran R. oryzae KJJ39 koji (15.5 degrees Brix) and overall relatively higher in the samples with wheat-bran koji than rice koji. The content of reducing sugar was twofold higher in rice wine prepared by koji inoculated with R. oryzae KJJ39 than A. oryzae KSS2. The volatile acid content was higher in rice wine produced by the wheat-bran A. oryzae KSS2 koji than the others. In the analyses of five organic acids, A. oryzae KSS2 was found to produce more malic acid and fumaric acid while R. oryzae KJJ39 to do more citric acid, lactic acid and acetic acid. The rice wine sample prepared with the wheat-bran A. oryzae KSS2 koji contained much higher concentration of sucrose, maltose and amino acids. Comprehensively, the results of fermentation profiling suggest that both A. oryzae KSS2 and R. oryzae KJJ39 can be applied to the production of rice wine as a valuable fungal isolate for fermentation start.

Joint effect of blood pressure and C-reactive protein and the risk of sudden cardiac death: A prospective cohort study

Background: Both blood pressure and C-reactive protein (CRP) are each independently related to mortality risk. However, the combined effect of systolic blood pressure (SBP) and CRP on sudden cardiac death (SCD) risk has not been studied. Patients and methods: We studied the joint impact of SBP and CRP and the risk of SCD in the Kuopio ischemic Heart Disease prospective cohort study of 1953 men aged 42-61 years with no history of ischemic heart disease. Baseline investigations were conducted between March 1984 and December 1989. SBP and CRP were measured. SBP was divided based on median values to low and high (median cutoffs 132 mmHg) and CRP as low and high (median cut-off 1.30 mg/L). Hazard ratios (HRs) with confidence intervals (CIs) were calculated after multivariate adjustment. Results: Subjects were followed-up for 23.2 years, and 137 SCDs occurred. In this study, elevated OP (>132 mmHg) combined with elevated (CRP >1.30 mg/L) were associated with SCD risk. Adjustment for age, examination year, alcohol consumption, BMI, energy expenditure during exercise, total cholesterol, HDL-cholesterol, type 2 diabetes, smoking, antihypertension medication and aspirin use, the risk of SCD remained statistically significant (HR, 2,73, 95% CI, 1.62-4.60, p < .001). Further adjustment for socio-economic status, years of education and history of cardiovascular disease in a family the results were only slightly changed (HR, 2.65,95% CI, 1.57-4.49, p < .001). Conclusions: In our male cohort study, the joint effect of high SBP together with increased CRP levels is a risk predictor of SCD compared with low SBP and CRP. (C) 2020 Published by Elsevier B.V.

Trait impulsivity and health risk behaviors: A latent profile analysis

Substance use and risky sexual behavior are negative health outcomes associated with the heterogeneous construct of impulsivity and emerging adulthood. The present study appears to be the first to examine how different facets of impulsive personality may be used to depict various profiles that differentially predict engagement in substance use and risky sexual behavior. Specifically, this study extends previous research by providing a comprehensive examination of impulsivity profiles in relation to various health risk outcomes via negative urgency, lack of premeditation, lack of perseverance, sensation seeking, and positive urgency. Participants (N = 599) completed the Short Urgency, Premeditation, Perseverance, Sensation Seeking, and Positive Urgency Scale (SUPPS-P), the Youth Risk Behavior Survey (YRBS), and the Student Sexual Risks Scale (SSRS). Impulsivity profiles were examined using latent profile analysis in which varying degrees of the SUPPS-P facets were grouped together based on participant response patterns. Results of latent profile analyses indicated an optimal 5-profile solution (low total impulsivity, moderate total impulsivity, high lack of premeditation/lack of perseverance facets, moderate positive urgency/negative urgency/sensation seeking facets, high positive urgency/negative urgency/sensation seeking facets).

Examining the effects of problematic alcohol use on cigarette abstinence in recently diagnosed cancer patients enrolled in a cessation trial: A secondary analysis

Aims: Among people with cancer, dual alcohol and tobacco use increases risk for morbidity and mortality. Most smoking cessation clinical trials with this patient population have excluded individuals with problematic alcohol use. This investigation examined whether problematic alcohol use affects smoking cessation in cancer patients. Methods: Mixed-methods secondary analysis of data from the Smokefree Support Study, a randomized-controlled trial examining the efficacy of Intensive (IT; n = 153) vs. Standard Treatment (ST; n = 150) for smoking cessation in newly diagnosed cancer patients. Problematic alcohol use was assessed at enrollment using the Cut-Down Annoyed-Guilty-Eye-Opener (CAGE), weekly frequency of alcohol use and binge drinking measures. Alcohol use was categorized as: no current alcohol use, moderate and problematic use. The primary outcome was biochemically-confirmed cigarette abstinence at 6-months. A subset of patients (n = 72) completed qualitative exit-interviews. Results: Among all participants, biochemically-confirmed cigarette abstinence rates were 25% (n = 32), 28% (n = 27), and 36% (n = 20) for participants reporting no current alcohol use, moderate use, and problematic use, respectively (p = 0.33). In logistic regression analysis, neither problematic alcohol use (AOR = 0.96, 95% CI = 0.35-2.67, p = .94) nor the problematic use by study arm interaction (AOR = 2.22, 95% CI = 0.59-8.39, p = .24) were associated with biochemically-confirmed 6-month abstinence. Qualitatively, participants reported that drinking alcohol triggers urges to smoke. Conclusion: Newly diagnosed cancer patients reporting problematic alcohol use were not less likely to quit smoking than those without. Additional research is needed to investigate whether problematic alcohol users may benefit from smoking and alcohol behavior change interventions at the time of cancer diagnosis.
