Development of bio oil and bio asphalt by hydrothermal liquefaction using lignocellulose

Bio asphalt is an organic polymer derived from biomass resources, which has the potential to partially or completely replace petroleum asphalt. This study used lignocellulose to prepare bio oil by hydrothermal liquefaction method. A mixed solvent of ethanol and ethylene glycol was introduced to increase the oil yield and decrease the reaction temperature. The oil yield reached the highest when solvent mixing ratio of 1:1, liquid-solid ratio of 6:1, catalyst dosage of 3%, and reaction temperature of 250 degrees C respectively. The bio oil and 50# asphalt were mixed in proportion sheared for 30 min (1000 rpm) under the condition of 135 degrees C to produce bio asphalt. The chemical structures and rheological properties of bio oil and bio asphalt were investigated and compared with petroleum asphalt. Fourier transform infrared spectroscopy (FTIR) and Nuclear Magnetic Resonance analysis indicate that the bio oil expressed a lower H/C ratio, higher O content and more light components including liquid compounds comparing to the petroleum asphalt. The content of the polar group including O-H and C=O of bio oil was higher than that of petroleum asphalt. Gas Chromatography-Mass Spectrometry (GC-MS) was used to prove the presence of olefins and alcohols in bio oil. Thermogravimetric analysis showed that the bio oil expressed better thermal stability than that of petroleum asphalt, which expressed a potential of using as a pavement material. The dynamic shear rheometer (DSR) results showed that the complex shear modulus, G* decreased as the content of bio oil. The Glass transition temperature Tg indicated that the bio asphalt with 10% bio oil content showed similar performance with that of 70# asphalt. (C) 2020 Published by Elsevier Ltd.

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.

Interactive Effects of Quality of Life and Related Factors on Alcohol Use Outcomes

This investigation derives its impetus from public health concerns around detecting, mitigating, and preventing the deleterious effects that alcohol use can cause particularly in advanced age. We aim to complement gerontological research by exploring the interactive effects of quality of life and related factors on alcohol use outcomes assessed by the Drinking Problem Index. The study is based on cross-sectional data collected from questionnaires mailed to a randomly drawn sample of 6,000 Norwegian adults aged 62 and older (participation rate: 32%). According to the Chi-square Automatic Interaction Detection (CHAID) analysis, constellations of interactive factors emerged differently for women and men, and, between non-problem and problem drinkers. For women, drinking outcomes were related to intra-psychic functioning, and for men, to physical health and social situation. An ongoing quality-of-life assessment may be very important in the comprehensive assistance provided to those older people who are vulnerable to undergoing alcohol-related harms.

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 1562-00-1 help many people in the next few years. Application In Synthesis of Sodium isethionate.

Influence of Higher Alcohol Additives in Methanol-Gasoline Blends on the Performance and Emissions of an Unmodified Automotive SI Engine: A Review

More stringent emission norms are implemented all over the world to protect the environment from vehicular pollution. Biofuels are one of the best alternative solutions to reduce cost and environmental pollution. Among many alternate fuels, alcohol is a leading fuel used in automotive spark-ignition engines in pure or blended form. The capability of methanol to substitute gasoline has been known for a long time. This paper aims to systematically review methanol-gasoline blend with higher alcohol additives (ternary blends) as a transportation fuel in unmodified automotive spark-ignition engines. This review summarizes the previous research in methanol-gasoline blends with and without additives on spark-ignition engines’ performance and emission characteristics. Many researchers found that methanol-gasoline blended fuels improve engine performance and emissions. Generally, alcohols burn very effectively and produce only fewer emissions compared to gasoline. Still, lower alcohol may cause some problems such as increased specific fuel consumption, phase separation and corrosion. These problems are further optimized using higher alcohol additives through improved energy content, kinematic viscosity, corrosion resistance, water tolerance and phase stability. Several research studies have been carried out in the past years, which focused mainly on single alcohol blended fuels for spark-ignition engines. Thus, a comprehensive survey of performance, combustion and emission characteristics of methanol-gasoline blended fuel with higher alcohol additives is necessary to show the potential of ternary blends in automotive engines.

Reward-related attentional capture predicts non-abstinence during a one-month abstinence challenge

Background: While it is generally recognised that cognitive attributes can predict behaviour change outcomes in the field of addiction this question is typically studied in treatment seeking samples (to predict treatment outcomes and relapse). However the concept of behaviour change applies to the entire spectrum of addiction-like behaviours and initiatives such as temporary abstinence challenges offer insight into an understudied but equally relevant point of the spectrum. Thus the current study examined whether reward-related attentional capture predicted non-abstinence during IkPas (the Dutch national dry January campaign translated: NoThanks!). Method: Participants included 1130 adults who had complete baseline data and performed above chance level on the cognitive task. Of these 683 participants completed the post-IkPas assessment and were included in the primary analysis. A binary logistic regression examined whether reward-related attentional capture predicted drinking during IkPas controlling for alcohol use at baseline (among other potential confounders). Results: Participants who showed greater reward-related attentional capture before IkPas were more likely to not remain abstinent from drinking during IkPas (p= .014). Findings were replicated using multiple imputation to replace missing data (p = .013). Conclusion: These findings provide important insights into the cognitive mechanisms that support successful behaviour change such as the ability to ignore task-irrelevant reward cues and may inform the development of tools that individuals could use to maximise their likelihood of achieving successful behaviour change.

Research on repeatability and stability of sensors based on alcohol-filled photonic crystal fiber

A novel fiber sensor based on photonic crystal fiber (PCF) for simultaneous measurement of temperature and humidity is proposed. The PCF is filled with alcohol, which is sensitive to temperature. And it is coated with graphene oxide (GO), which is sensitive to humidity. In the range of 10 degrees C-70 degrees C, the highest temperature sensitivity of the three interference valleys can reach up to 0.182 nm/degrees C. Similarly, in the range of 30%-70%, the highest humidity sensitivity is 0.109 nm/%RH. This configuration features the advantages of reliable repeatability, strong stability, and it is ideal for environmental detection.

Techniques for measuring carbon and oxygen isotope compositions of atmospheric CO2 via isotope ratio mass spectrometry

Measuring the stable isotope compositions of atmospheric CO2 is common in earth and atmospheric sciences, and various analytical methods have been developed utilizing continuous-flow (CF) or dual-inlet (DI) isotope ratio mass spectrometry (IRMS). Air is typically collected via passive, manual, or automated collection methods and the volume of the air sample ranges from 10 to 300 mL for CF-IRMS to >1 L for DI-IRMS to yield a measurable amount of atmospheric CO2 gas. It has been determined that the integrity of vials and flasks for air sample storage can be compromised after 3 days of air collection for delta C-13 values and within 10 hours for delta O-18 values. Air samples must be purified after collection to remove constituents of air, such as Ar, O-2, N-2, N2O, and water vapor, to avoid isobaric interferences during mass spectrometric measurement. Purification is generally undertaken by utilizing commercial or custom-made preconcentration devices, the blanking method for CF-IRMS, or an offline/online cryogenic separation using a vacuum line for DI-IRMS. Ambient N2O is a component of air that may affect analytical results and thus must either be corrected for or be removed using a gas chromatographic column. In some cases, water is removed during air collection by using a common chemical desiccant, magnesium perchlorate (Mg(ClO4)(2)), or by a dry ice/alcohol mixture (-78 degrees C). Lastly, a linearity issue for IRMS due to the low amount of purified CO2 from a typical ambient air sample must be considered. In general, analytical precisions of 0.02-0.21 parts per thousand and 0.04-0.34 parts per thousand for CF-IRMS and 0.01-0.02 parts per thousand and 0.01-0.02 parts per thousand for DI-IRMS are expected for delta C-13 and delta O-18 measurements, respectively.

Fast-Track Liver Transplantation: Six-year Prospective Cohort Study with an Enhanced Recovery After Surgery (ERAS) Protocol

Introduction Enhanced recovery after surgery (ERAS) has been shown to facilitate discharge, decrease length of stay, improve outcomes and reduce costs. We used this concept to design a comprehensive fast-track pathway (OR-to-discharge) before starting our liver transplant activity and then applied this protocol prospectively to every patient undergoing liver transplantation at our institution, monitoring the results periodically. We now report our first six years results. Patients and methods Prospective cohort study of all the liver transplants performed at our institution for the first six years. Balanced general anesthesia, fluid restriction, thromboelastometry, inferior vena cava preservation and temporary portocaval shunt were strategies common to all cases. Standard immunosuppression administered included steroids, tacrolimus (delayed in the setting of renal impairment, with basiliximab induction added) and mycophenolate mofetil. Tacrolimus dosing was adjusted using a Bayesian estimation methodology. Oral intake and ambulation were started early. Results A total of 240 transplants were performed in 236 patients (191 male/45 female) over 74 months, mean age 56.3 +/- 9.6 years, raw MELD score 15.5 +/- 7.7. Predominant etiologies were alcohol (n = 136) and HCV (n = 82), with hepatocellular carcinoma present in 129 (54.7%). Nine patients received combined liver and kidney transplants. The mean operating time was 315 +/- 64 min with cold ischemia times of 279 +/- 88 min. Thirty-one patients (13.1%) were transfused in the OR (2.4 +/- 1.2 units of PRBC). Extubation was immediate (< 30 min) in all but four patients. Median ICU length of stay was 12.7 hours, and median post-transplant hospital stay was 4 days (2-76) with 30 patients (13.8%) going home by day 2, 87 (39.9%) by day 3, and 133 (61%) by day 4, defining our fast-track group. Thirty-day-readmission rate (34.9%) was significantly lower (28.6% vs. 44.7% p=0.015) in the fast-track group. Patient survival was 86.8% at 1 year and 78.6% at five years. Conclusion Fast-Tracking of Liver Transplant patients is feasible and can be applied as the standard of care If you’re interested in learning more about 1606-85-5.

Magnetized ZIF-8 impregnated with sodium hydroxide as a heterogeneous catalyst for high-quality biodiesel production

A magnetized zeolitic imidazolate framework (ZIF-8) impregnated with sodium hydroxide catalyst has been synthesized and tested as a new catalyst for biodiesel production. The new catalyst was investigated for the ethanolysis of vegetable oil to produce biodiesel. The operating conditions of the biodiesel production were optimized using the 2n design method followed by a reduced number of experimental runs. A 70% conversion of oil in the ethanolysis reaction was achieved using the new catalyst. The optimized operating conditions were found to be alcohol to oil molar ratio of 21:1, catalyst loading of 1% wt., a reaction time of 90 min, and temperature of 75 degrees C. Ethanolysis reaction was found to obey the pseudosecond-order kinetic model. In addition, the Arrhenius pre-exponential constant and activation energy were calculated to be 1.12 x 10(10) L mol(-1).min(1) and 77.27 kJ/mol, respectively. The physical properties of the product biodiesel matched the American Society for Testing and Materials (ASTM) ranges. Additionally, the product biodiesel achieved a Cetane number of 75, which is 15% higher than the upper range of the ASTM. (C) 2020 Elsevier Ltd. All rights reserved.

The toxic side of one-carbon metabolism and epigenetics

One-carbon metabolism is a central metabolic hub that provides one-carbon units for essential biosynthetic reactions and for writing epigenetics marks. The leading role in this hub is performed by the one-carbon carrier tetrahydrofolate (THF), which accepts formaldehyde usually from serine generating one-carbon THF intermediates in a set of reactions known as the folate or one-carbon cycle. THF derivatives can feed one-carbon units into purine and thymidine synthesis, and into the methionine cycle that produces the universal methyl donor S-adenosylmethionine (AdoMet). AdoMet delivers methyl groups for epigenetic methylations and it is metabolized to homocysteine (Hcy), which can enter the transsulfuration pathway for the production of cysteine and lastly glutathione (GSH), the main cellular antioxidant. This vital role of THF comes to an expense. THF and other folate derivatives are susceptible to oxidative breakdown releasing formaldehyde, which can damage DNA-a consequence prevented by the Fanconi Anaemia DNA repair pathway. Epigenetic demethylations catalysed by lysine-specific demethylases (LSD) and Jumonji histone demethylases can also release formaldehyde, constituting a potential threat for genome integrity. In mammals, the toxicity of formaldehyde is limited by a metabolic route centred on the enzyme alcohol dehydrogenase 5 (ADH5/GSNOR), which oxidizes formaldehyde conjugated to GSH, lastly generating formate. Remarkably, this formate can be a significant source of one-carbon units, thus defining a formaldehyde cycle that likely restricts the toxicity of one-carbon metabolism and epigenetic demethylations. This work describes recent advances in one-carbon metabolism and epigenetics, focusing on the steps that involve formaldehyde flux and that might lead to cytotoxicity affecting human health.

Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law. In my other articles, you can also check out more blogs about 105-13-5. Application In Synthesis of (4-Methoxyphenyl)methanol.
