Developing the QSPR model for predicting the storage lipid/water distribution coefficient of organic compounds

The distribution of organic compounds in stored lipids affects their migration, transformation, bioaccumulation, and toxicity in organisms. The storage lipid/water distribution coefficient (log K-lip/w) of organic chemicals, which quantitatively determines such distribution, has become a key parameter to assist their ecological security and health risk. Due to the impossibility to measure K-lip/w values for a huge amount of chemicals, it is necessary to develop predictive approaches. In this work, a quantitative structure-property relationship (QSPR) model for estimating log K-lip/w values of small organic compounds was constructed based on 305 experimental log K-lip/w values. Quantum chemical descriptors and n-octanol/water partitioning coefficient were employed to characterize the intermolecular interactions that dominate log K-lip/w values. The hydrophobic and electrostatic interactions and molecular size have been found to play important roles in governing the distribution of chemicals between lipids and aqueous phases. The regression (R-2 = 0.959) and validation (Q(2) = 0.960) results indicate good fitting performance and robustness of the developed model. A comparison with the predictive performance of other commercial software further proves the higher accuracy and stronger predictive ability of the developed K-lip/w predictive model. Thus, it can be used to predict the K-lip/w values of cycloalkanes, long-chain alkanes, halides (with fluorine, chlorine, and bromine as substituents), esters (without phosphate groups), alcohols (without methoxy groups), and aromatic compounds.

Fabrication of carboxymethyl chitosan/poly(epsilon-caprolactone)/doxorubicin/nickel ferrite core-shell fibers for controlled release of doxorubicin against breast cancer

The coaxial electrospinning for producing core-shell nanofibers due to control the release profile of drug by the shell layer has been developed. N-carboxymethyl chitosan (CMC)-polyvinyl alcohol (core)/poly(epsilon-caprolactone) (PCL) (shell) nanofibers were produced via coaxial electrospinning. Doxorubicin (DOX) and nickel ferrite nanoparticles were incorporated into the nanofibers for controlled release of DOX against MCF-7 breast cancer. The minimum CMC/PCL fiber diameter was found to be 300 nm by optimizing of three variables including voltage to distance ratio (1.5-2.5 kV/cm), CMC concentration (4-6 wt.%) and PCL concentration (8-12 wt.%). The synthesized core-shell fibers were characterized using FTIR, XRD, SEM, and TEM analysis. The extended release and controlled release of DOX from core-shell nanofibers were achieved under physiological pH without external magnetic field (EMF) and acidic pH with EMF during 25 and 7 days, respectively. The maximum cytotoxicity of MCF-7 breast cancer cells was about 83 % using CMC/PCL/nickel ferrite 10 % nanofibers and EMF.

A high ZIF-8 loading PVA mixed matrix membrane on alumina hollow fiber with enhanced ethanol dehydration

In this work, a zeolitic imidazolate framework-8 (ZIF-8)/polyvinyl alcohol (PVA) mixed matrix membrane (MMM) was coated onto a-aluminum oxide (alpha-Al2O3 ) hollow fibers for ethanol dehydration by utilizing the pervaporation technique. ZIF-8/PVA solution was prepared via a drying-free, water-based method to obtain a uniform distribution MMM. Before coating the MMM onto the hollow fiber, a pristine PVA solution was first dipcoated onto hollow fiber as a gutter layer to prevent phase separation. Different weight ratios of ZIF-8-loaded MMMs were prepared. The results showed that at high ZIF-8 loading (39 wt %), a high permeate flux (685 g/ m(2) h) and high separation factor (4821) can be observed. Furthermore, compared with free-standing ZIF-8/PVA MMMs, hollow fiber supported ZIF-8/PVA MMMs exhibit a thinner coating thickness but higher pervaporation separation index (approximately 1.5-2 times). The main contribution of this study is not only fabricated the high loading ZIF-8/PVA composite membrane with enhanced performance, but also coated onto the hollow fiber membrane which opens a gate for scale-up production.

New tetradentate Schiff base Cu(II) complexes: synthesis, physicochemical, chromotropism, fluorescence, thermal, and selective catalytic oxidation

Three neutral Cu(II)/n(4)-NNNO Schiff base complexes (1-3) were prepared from the (E)-4-nitro-2-(((2-(piperazin-1-yl)ethyl)imino)methyl)phenol, tetradentate Schiff base (SB) ligand, and the corresponding copper(II) salts. The new SB and its complexes were fully characterized by CHN-EA, standard spectroscopic, thermal, and fluorescence analyses. The formation of the complexes was monitored by EDX, FT-IR, and UV-Vis. The chromotropism studies of the complexes reflected remarkable findings, in which bathochromic solvato- and thermochromism shifts were detected. The turn-off-on halochromism phenomena were observed in the acidic and basic medium. On the other hand, the fluorescence of the free SB ligand was turned off via complexation to the Cu(II) center. In the presence of H2O2 as green oxidant and under mild oxidation catalytic condition, the three complexes successfully catalyzed the formation benzaldehyde from benzyl alcohol.

An experimental assessment on low temperature combustion using diesel/ biodiesel/C2, C5 alcohol blends in a diesel engine

Alcohol additives in Diesel-Biodiesel (DB) blends were investigated on a modified single cylinder diesel engine with exhaust gas recirculation (EGR). The effects of lower and higher alcohol contents (10% ethanol, 20% ethanol and 10% pentanol by volume) with various EGR rates on combustion characteristics and emissions were evaluated. The results indicated that with the increase of EGR rates and increasing fraction of ethanol in DB blends, the ratio of premixed combustion will increase and the ignition delay (ID) will prolong, which lead to the increase of maximum pressure rise rate and peak value of heat release rate. Indicated thermal efficiency (ITE) increased firstly with EGR increasing and then decreased rapidly, but the EGR rates corresponding to the rapid decrease of ITE for the blends will be low compared to pure diesel. The Diesel-Biodiesel-Ethanol (DBE, the lower alcohol) blends showed the best performance on soot emissions among all the tested fuels even though there is no EGR. What’s more, the DBE blends showed better nitrogen oxide (NOx) and carbon monoxide (CO) emissions at high EGR. However, the Diesel-Biodiesel-Pentanol (DBP, the higher alcohol) blends performed better THC emissions. Overall consideration, using diesel/biodiesel/ethanol ternary fuels under medium EGR rates may be a better choice for diesel engines.

Effect of Hericium erinaceus on bacterial diversity and volatile flavor changes of soy sauce

At present, the consumer demand for high-quality soy sauce is growing. Hericium erinaceus, an edible mushroom with many health benefits, was used for soy sauce fermentation. Firmicutes and Proteobacteria were identified as the main phyla, while, Bacillus and Stenotrophomonas as the predominant genera during soy sauce fermentation. H. erinaceus decreased the richness and diversity of bacteria during soy sauce fermentation due to its antimicrobial effect. Especially, Stenotrophomonas, a common opportunistic pathogen, was replaced by Bacillus during soy sauce fermentation by adding H. erinaceus. Moreover, H. erinaceus significantly promoted the esters and alcohols accumulation, and had positively influenced on a sensory constituent. However, pyrazines, ketones, and alkanes were rich in the control samples. Bacillus, Staphylococcus, and Psychrobacter showed a positive correlation to flavor formation with the addition of H. erinaceus. This study provided new insight into regulating the quality and microbial community of soy sauce by changing the raw material ingredients.

Smoke in the air – Associations between experimentation with cannabis and the use of tobacco and nicotine products among 15-16-year-old school students

Background: Cannabis is the most popular illicit drug among adolescents in developed countries, including Finland. The aim of this study was to estimate 1) how cannabis experimentation among Finnish adolescents changed between 2003 and 2019, and 2) whether the associations between cannabis experiments and factors related to it, especially the use of tobacco and nicotine products, changed during the same time period. Methods: The analyses are based on the European School Survey Project on Alcohol and Other Drugs data, collected from Finnish adolescents aged 15 to 16 in 2003, 2007, 2011, 2015, and 2019 (N = 20,630). Results: Experimentation with cannabis among Finnish adolescents has increased since the beginning of our follow-up. At the same time, alcohol use and smoking have decreased markedly, and attitudes toward cannabis use have become more relaxed. The association between smoking and cannabis experimentation has become weaker over time. However, the use of tobacco and nicotine products, especially polytobacco, is still a strong risk factor for experimentation with cannabis. The higher the number of tobacco or nicotine products used, the higher the probability for cannabis experimentation. Conclusions: Experimentation with cannabis has previously been concentrated predominantly on adolescents who smoke, but recently non-smokers are increasingly trying cannabis. It is possible that alternative ways of using cannabis may have increased its use. Despite the strict cannabis policy in Finland, its use has increased, which may be an indication that youth cultures and images of different substances play a significant role in adolescents experimenting with cannabis.

Liquefaction of biomass by plasma electrolysis in alkaline condition

We investigated the discharge characteristics, parameters, water content, and mechanism of liquefying biomass by plasma electrolysis under alkaline conditions. Compared with the liquefaction of sawdust under acidic conditions, the discharge changed from corona to spark discharge, the liquefaction time was a little longer (8 min), and the pondus Hydrogenii (pH) of the bio-oil was 7.54 under sodium hydroxide catalyst. We identified the optimal parameters for sawdust liquefaction by sodium hydroxide, sodium carbonate, and sodium bicarbonate using a single factor method and found that the optimal parameters for sodium hydroxide and carbonate were quite different, apparently because they have different liquefaction mechanisms. When the water content increased, the liquefaction rate remained constant, so the water content prolonged the treatment time but did not affect the liquefaction rate or product quality. To analyze the universality of liquefied cellulose biomass under alkaline conditions, corn cob, rice straw, and cotton were liquefied separately. We found that the liquefaction time increased significantly with an increase in cellulose content. Notably, plasma electrolytic liquefaction efficiently heated the solution and effectively catalyzed the liquefaction of biomass with high energy efficiency, making this a promising biomass conversion technology.

Technical feasibility of biodiesel production from virgin oil and waste cooking oil: Comparison between traditional and innovative process based on hydrodynamic cavitation

Biodiesel production calls for innovative solutions to turn into a competitive process with a reduced environmental impact. One of the process bottlenecks stands in the immiscibility of oil and alcohol as raw materials, so mixing process largely impacts the overall process cost. This process step, if carried out by using hydrodynamic cavitation, has the possibility to become a benchmark for large scale applications. In this paper a process analysis of biodiesel production scheme is developed starting from two different feedstocks, virgin oil and waste cooking oil. At the first the traditional process scheme has been simulated, in a second simulation, the reactor for the biodiesel production is interchanged with a hydrodynamic cavitation reactor. In the paper, the comparison between the traditional and innovative process by using life cycle costing approach has been presented, thus providing indications for industrial technological implementation coming from a professional tool for process analysis. It is worth noting that the introduction of hydrodynamic cavitation reduces of about 40% the energy consumption with respect to the traditional process. As regards the total treatment costs, when using virgin oil as feedstock, they were in the range 820-830 6/t (innovative and traditional process, respectively); while starting from waste cooking oil the costs decreased of about 60%, down to 290-300 6/t (innovative and traditional process, respectively).
