Hydrogen-free hydrogenation of furfural to furfuryl alcohol and 2-methyl-furan over Ni and Co-promoted Cu/gamma-Al2O3 catalysts

Catalytic transformation of furfural to furfuryl alcohol and 2-methylfuran without H-2 supply toward transfer hydrogenation process using 2-propanol as a H-2 source was systematically investigated over the bimetallic NiCuAl and CoCuAl catalysts in comparison with the monometallic CuAl, NiAl, and CoAl catalysts. The XRD analysis confirmed the generation of Ni-Cu and Co-Cu alloys after the reduction in presence of H-2. The interaction between Cu and Ni or Co resulted in a simplicity of the reduction behavior of Ni and Co species observed in H-2-TPR experiments. It was evident from pyridine adsorption FTIR analysis that the formation of bimetallic NiCu and Co-Cu alloys apparently improved the stronger Lewis acidic sites. The influences of reaction temperature and time were examined and optimized to maximize the yields of furfuryl alcohol and 2-methylfuran. The highest two major products yield and selectivity with lower by-products were obtained over the NiCuAl and CoCuAl catalysts compared with the CuAl and NiAl catalysts. The superior performance of the bimetallic catalysts was attributed to the stronger Lewis acidic centre on the catalyst surface. The CoCuAl catalyst was found to have lower catalyst deactivation and carbon deposition among the CuAl and NiCuAl catalysts under H-2-free atmosphere.

A novel Bi-based crystalline molecular material: fluorescence response of the high efficient detection and recognition of the organic amines and white luminescence tuning

A novel Bi-based crystalline molecular materials Bi(C2O4)(3)(NMP)(2) (Bi-NMP) have successfully synthesized by the reaction of Bi(NO3)(3)center dot 5H(2)O, N-Methylpyrrolidone (NMP) in the solution of methyl alcohol. Structural analysis indicates that the Bi-NMP shows a novel 2D planar structure. The luminescent behavior for the Bi-NMP has been investigated at room temperature. The results have shown that Bi-NMP can be used as a chemical sensor for multifunctional testing such as aliphatic amines and aromatic amines detection, because of its strong fluorescence properties. When detecting cyclohexylamine (CHA), the K was 2.5 x 10(5) M–(1),( )and the detection limit was 0.99 mu M. When detecting m-phenylenediamine(MPD), the K-sv was 5.5 x 10(3) M-1, and the detection limit was 45.7 mu M. When detecting o-phenylenediamine (OPD), the K was 5.4 x 10(3) M-1, and the detection limit of Bi-NMP was calculated to be 49.9 mu M. In particular, for o-phenylenediamine (OPD), Bi-NMP has a unique switching effect. Therefore, Bi-NMP has not only a detection function but also a recognition function for o-phenylenediamine (OPD), m-phenylenediamine (MPD) and p-phenylenediamine (PPD). In addition, white-light emission is achieved through a reasonable tuning proportion by mixing Sm-3(+) in Bi-NMP. (C) 2020 Elsevier B.V. All rights reserved.

Biocompatible, antibacterial, polymeric hydrogels active against multidrug-resistant Staphylococcus aureus strains for food packaging applications

Microbial infections caused by multidrug-resistant (MDR) bacteria have become a public health threat and cause substantial morbidity and mortality in hospitals as well as in the community and livestock. Pseudomonas aeruginosa YUSA1 isolated from freshwater was found to contain an antagonistic compound against MRSA and other MDR S. aureus strains. The crude ethyl acetate extract (CEE) of cell-free supernatant exhibited in vitro antibacterial and antibiofilm properties against MRSA. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) values of CEE (as determined by broth-dilution) against MRSA were 25 and 50 mu g/ml, respectively. The effect of CEE on MRSA biofilm formation was assessed by crystal violet staining and an MTT viability assay. Pretreatment of human skin fibroblasts (HSFs) with CEE dose-dependently inhibited MRSA adhesion and invasion, and in vitro cytotoxicity analysis showed CEE was compatible with HSFs at its MIC and MBC. In addition, an CEE containing poly(vinyl alcohol) (PVA/CEE) hydrogel fabricated by freeze-drying method exhibited significant anti-MRSA activity at concentrations >= 200 mu g/ml. Our results indicate CEE-incorporated PVA polymeric hydrogels have potential use as a food packaging material with antibacterial and antifouling effects on MRSA and other MDR S. aureus strains.

Integrated approaches to testing and assessment as a tool for the hazard assessment and risk characterization of cosmetic preservatives

The safety assessment of cosmetic products is based on the safety of the ingredients, which requires information on chemical structures, toxicological profiles, and exposure data. Approximately 6% of the population is sensitized to cosmetic ingredients, especially preservatives and fragrances. In this context, the aim of this study was to perform a hazard assessment and risk characterization of benzalkonium chloride (BAC), benzyl alcohol (BA), caprylyl glycol (CG), ethylhexylglycerin (EG), chlorphenesin (CP), dehydroacetic acid (DHA), sodium dehydroacetate (SDH), iodopropynyl butylcarbamate (IPBC), methylchloroisothiazolinone and methylisothiazolinone (MCI/MIT), methylisothiazolinone (MIT), phenoxyethanol (PE), potassium sorbate (PS), and sodium benzoate (SB). Considering the integrated approaches to testing and assessment (IATA) and weight of evidence (WoE) as a decision tree, based on published safety reports. The hazard assessment was composed of a toxicological matrix correlating the toxicity level, defined as low (L), moderate (M), or high (H) and local or systemic exposure, considering the endpoints of skin sensitization, skin irritation, eye irritation, phototoxicity, acute oral toxicity, carcinogenicity, mutagenicity/genotoxicity, and endocrine activity. In a risk assessment approach, most preservatives had a margin of safety (MoS) above 100, except for DHA, SDH, and EG, considering the worst-case scenario (100% dermal absorption). However, isolated data do not set up a safety assessment. It is necessary to carry out a rational risk characterization considering hazard and exposure assessment to estimate the level of risk of an adverse health outcome, based on the concentration in a product, frequency of use, type of product, route of exposure, body surface location, and target population.

Selective production of furfural and phenols from rice husk: the influence of synergetic pretreatments with different order

The subject of this study was to upgrade the pyrolysis bio-oil by torrefaction combined with different order of acid washing. The pyrolysis behavior of biochar obtained from different pretreatments were investigated by a thermogravimetric analyzer (TGA) and fixed furnace. Moreover, the composition of biooil was systematically analyzed by GC-MS. The results showed that torrefaction promoted the aggregation of phenols in bio-oil through removing the hemicellulose and part of cellulose. In addition, aldehydes had increased significantly after acid washing. The acid washing combined with torrefaction could reduce the formation of acids, alcohols and other organic substances except for phenols, aldehydes and ketones. Compared with the pyrolysis bio-oil obtained by directly torrefaction pretreatment, the absolute content of phenols in the pyrolysis bio-oil was slightly reduced from 74 mg/gRH to 63 mg/gRH after first inorganic acid washing and then torrefaction, while the absolute content of furfural increased from 2.8 mg/gRH to 16 mg/gRH. The mechanism showed that the furfural was selected by the catalysis of acid and the torrefaction promoted the cellulose to convert to 1-hydroxy-2-propanone by cracking reaction. This study provided a simple and practical method for the selective production of furfural and phenol from rice husk. (c) 2020 Elsevier Ltd. All rights reserved.

Self-healing and acidochromic polyvinyl alcohol hydrogel reinforced by regenerated cellulose

Recently, integration of self-healing, color-tunable, sol-gel converted properties into hydrogel has attracted interest for preparing a reinforced multifunctional hydrogel. Herein, acidochromic regenerated cellulose (ARC) was incorporated into the polyvinyl alcohol/borax (PB) matrix for constructing a tough, self-healing, multicolor and sol-gel converted smart hydrogel (PB/ARC). The mechanical properties of PB/ARC hydrogel were improved after introducing ARC, which could bear a weight of 200 g and had high maximum tensile strength (6.8 times) and compressive strength (2.3 times). PB/ARC hydrogel automatically fused within 15 s after being cut and quickly recovered to the original state after being subjected to high shear strain, showing excellent self-healing ability. The color of hydrogel could be tuned between yellow and purple by altering pH values (5-12). In addition, PB/ARC hydrogel exhibited reversible sol-gel conversion in response to the change of acidity and alkalinity. This study offers a new and facile strategy for developing multifunctional smart hydrogel.

Investigation of the intrinsic reaction kinetics and the mass transfer phenomena of nonanoic acid esterification with 2-ethylhexanol promoted by sulfuric acid or Amberlite IR120

Nonanoic acid is obtained as main coproduct in the synthesis of azelaic acid from oleic acid. The increase of azelaic acid production, being a monomer useful to synthesize biodegradable polyesters, lead to a high availability of nonanoic acid, that can be used as feedstock in esterification reactions to obtain lubricants and solvents. In this work, the esterification of nonanoic acid with 2-ethylhexanol to produce a solvent were conducted in a batch reactor in the presence of either a homogeneous (H2SO4) or an heterogenous catalyst (Amberlite IR120). The intrinsic reaction kinetics was investigated by considering all the physical and chemical phenomena occurring in the reaction network, leading to the determination of thermodynamic and kinetic parameters. The activation energy values of both catalysts are similar (approximate to 60 kJ/mol) and the enthalpy value of Delta H-r = 10.3 kJ/mol showed that the reaction is slightly endothermic. The reaction is shifted to the products as demonstrated by the reference equilibrium constant equal to 1.69 at 333 K. The obtained results will be useful to design industrial reactors.

The impact of emotional face stimuli on working memory performance among men and women with alcohol use disorder

Background: Individuals with alcohol use disorder (AUD) often display compromise in emotional processing and non-affective neurocognitive functions. However, relatively little empirical work explores their intersection. In this study, we examined working memory performance when attending to and ignoring facial stimuli among adults with and without AUD. We anticipated poorer performance in the AUD group, particularly when task demands involved ignoring facial stimuli. Whether this relationship was moderated by facial emotion or participant sex were explored as empirical questions. Methods: Fifty-six controls (30 women) and 56 treatment-seekers with AUD (14 women) completed task conditions in which performance was advantaged by either attending to or ignoring facial stimuli, including happy, neutral, or fearful faces. Group, sex, and their interaction were independent factors in all models. Efficiency (accuracy/response time) was the primary outcome of interest. Results: An interaction between group and condition (F-1,F-107 = 6.03, p < .02) was detected. Individual comparisons suggested this interaction was driven by AUD-associated performance deficits when ignoring faces, whereas performance was equivalent between groups when faces were attended. Secondary analyses suggested little influence of specific facial emotions on these effects. Conclusions: These data provide partial support for initial hypotheses, with the AUD group demonstrating poorer working memory performance conditioned on the inability to ignore irrelevant emotional face stimuli. The absence of group differences when scenes were to be ignored (faces remembered) suggests the AUD-associated inability to ignore irrelevance is influenced by specific stimulus qualities.

Enhanced photocatalytic degradation of gaseous toluene and liquidus tetracycline by anatase/rutile titanium dioxide with heterophase junction derived from materials of Institut Lavoisier-125(Ti): Degradation pathway and mechanism studies

Anatase/rutile titanium dioxide (TiO2) with heterophase junction and large Brunauer-Emmett-Teller (BET) specific surface area (50.1 m(2) g(1)) is successfully synthesized by calcinating Materials of Institut Lavoisier-125(Ti) (MIL-125(Ti)) with 30% O-2/Ar at the temperature of 600 degrees C (M-O-600). Several techniques are used to examine the physicochemical, photoelectrochemical and optical properties of samples, and their photocatalytic performances are evaluated by photodegradation of gaseous toluene and liquidus tetracycline (TC) under visible light illumination. It is found that the calcination temperature has significant influence on the crystal structure and physicochemical parameters of TiO2. The weight fractions of rutile and anatase TiO2 of M-600 are approximately 0.7 and 0.3, which displays outstanding photocatalytic activity. Through the construction of heterophase junction, M-O-600 has better oxygen adsorption and higher density of localized states, which effectively promotes the generation of superoxide radical (center dot O-2(-)) and hydroxyl radical (center dot OH) species. In-situ infrared spectra indicate that toluene is oxidized to benzyl alcohol, benzaldehyde and benzoic acid in turn and then oxidized to formic acid and acetic acid before eventually degraded into H2O and CO2. Gas chromatography-mass spectrometry (GC-MS) is also used to further investigate the degradation pathway of toluene. Degradation pathway and mechanism of TC are studied by liquid chromatography-tandem mass spectrometry (LC-MS). Moreover, three-dimensional excitation-emission matrix fluorescence spectroscopy (3D EEMs) and total organic carbon (TOC) show that TC can be effectively mineralized through a series of reactions by M-O-600 during photocatalysis.

Evaluation of polyvinyl alcohol and high calcium fly ash based geopolymer for the improvement of soft Bangkok clay

Soft Bangkok clay (SC) is recognized as a problematic soil in Thailand. This research investigates the possibility of using polyvinyl alcohol (PVA) and high calcium fly ash (FA) geopolymers to improve the strength of SC in deep soil mixing applications. The liquid alkaline activator (L) was composed of sodium silicate (Na2SiO3) and sodium hydroxide (NaOH). The studied influence factors included FA content, water content, L content, Na2SiO3/NaOH ratio, PVA concentration, PVA content, and curing time. Strength development and microstructure in the PVA-FA geopolymer stabilized SC were evaluated via the unconfined compressive strength (UCS) test and scanning electron microscope (SEM) test. The optimum ingredient considering workability and cost of FA geopolymer stabilized SC was found to be at a mix design of LOLL, Na2SiO3/NaOH = 1, FA = 40% and L/FA = 0.6, whereby a 28-day UCS of 1026 kPa was attained. The optimum PVA content and PVA concentrations were found at 15% and 4%. The 7-day and 28-day UCS values were improved by PVA up to 40% and 42% compared to those of the specimen without PVA, respectively. The outcome of this research will promote the usage of PVA-FA geopolymer as an alternative green soil stabilizer alternative to Portland cement for a DM improved soft Bangkok clay.
