Highly Thermal-Resistant and Biodegradable Textile Sizes from Glycols Modified Soy Proteins for Remediation of Textile Effluents

Poly(vinyl alcohol) (PVA) sizes are widely used in textile industry due to their excellent sizing properties on synthetic fibers and their blends. However, PVA contains non-biodegradable chemicals and is a major contributor to environmental pollution related to the textile industry. To overcome this problem, an environmental-benign and highly thermal-resistant yarn coating is fabricated from soy proteins, an agricultural byproduct. The soy proteins are chemically modified by glycols having varying chain lengths and number of hydroxyl groups. Compared with the physically modified soy proteins and their sized yarns, coating made from the soy proteins esterified by 1,4-butanediol show 91.38% increment in work of rupture at 120 degrees C and cotton/polyester (65/35) yarns sized by 1,4-butanediol esterified soy protein sizes have 39.91% decrease in coefficient of friction. In addition, 1,4-butanediol esterified soy sizes have a five-day biochemical oxygen demand/chemical oxygen demand of 0.476, indicating that the chemically modified soy sizes have high biodegradability in activated sludge. Successful utilization of modified soy sizes can promote large-quantity applications of soy byproducts, impelling high value addition to agricultural byproducts and sustainability of textile industry.

Optical and conductivity studies of polyvinyl alcohol-MXene (PVA-MXene) nanocomposite thin films for electronic applications

A new family of 2D materials known as MXenes (Ti3C2Tx) is combined with polyvinyl alcohol (PVA) to form nanocomposites thin film with a thickness in micrometre range (7.20-7.88 mu m) by using a relatively simple way, a drop-casting technique. The multi-layered structure of the MXenes bound together with PVA results in a high degree of structural disorder due to increasing defects in the nanocomposites. Detailed optical studies include UV-Vis absorption, optical absorption coefficient, extinction coefficient, and band gap energy determinations are conducted to investigate electromagnetic wave absorption capability of the nanocomposites. Resistivity measurement is studied as well. Electrical conductivity of the PVA is significantly increased with at least an improvement of 3000 times as compared to pure PVA (1 x 10(-13) Sm-1). The highest a value of 7.25 x 10(-3) Sm-1 is found in the nanocomposites with a mass ratio of PVA to MXenes, 80:20 with its calculated optical absorption coefficient value in range 4000-5000 cm(-1). The optical findings, as well as the electrical conductivity enhancement exhibited by these nanocomposites, explore the route to apply MXenes in polymer-based multifunctional nanocomposites for various applications such as optoelectronics, conductive filler, and electromagnetic absorbers.

Fire hazard prevention and protection in neurosurgical operating rooms revisited: A literature review challenged by a recent incident report

We present the case of an 11 month old boy with history of sagittal synostosis who underwent a cranial vault reconstruction for repair. During the case, surgical irrigation spilled onto the plug in the operating room table, resulting in sparks and a small fire. The fire was contained and extinguished. The patient suffered no injury. We discuss previous cases of fires in neurosurgical operating rooms and identify a new source of ignition for fires. We also explore recommended best practices for fire prevention and safety to identify ways to prevent instances like this from occurring in the future.

Photochemistry of biochar during ageing process: Reactive oxygen species generation and benzoic acid degradation

In this study, the photogeneration of center dot OH and O-1(2) and the degradation mechanism of organic pollutants in biochar suspension under the simulated solar light irradiations were investigated. Biochar derived from rice husk with 550 degrees C of charring temperature (R550) was selected to degrade benzoic acid. It was found that 10 g/L of R550 could degrade 78.7% of benzoic acid within 360 min at pH 3, and the degradation efficiency was promoted to 95.2% as ultraviolet (UV) presented. By checking the production of p-hydroxybenzoic acid, UV accelerated the production of center dot OH, which was confirmed by the enhanced degradation efficiency of 59.2% caused by the evaluated center dot OH as UV appeared. The furfuryl alcohol loss in the R550 suspension under light irradiations testified to the production of O-1(2), which contributed to 9.3% of benzoic acid degradation. Oxidization treatment using gradient concentrations of H2O2 was employed to enhance the ageing process of biochar. As the ageing processed, the biochar possessed a declined performance towards center dot OH production from O-2 activation and the radical degradation of organic pollutants. As a contrast, the evaluated content of O-1(2) and enhanced non-radical degradation of organic pollutants was reached as UV presented. The further study indicated that phenolic hydroxyl groups on biochar facilitated the production of center dot OH via the electron transfer, and quinone like structures (C=O) on biochar boosted the generation of O-1(2) via the energy transfer. Moreover, upon eliminating the BA degradation, persistent free radicals were formed on biochar, which was enhanced owing to the presence of UV. (C) 2020 Published by Elsevier B.V.

Enhanced anticorrosion properties of nitrogen ions modified polyvinyl alcohol/Mg-Ag ions co-incorporated calcium phosphate coatings

Nitrogen ions (70 keV) were implanted on composite coatings containing polymer/Mg (magnesium)-Ag (silver) ions co-incorporated hydroxyapatite which was developed using microwave irradiation. Average crystallite size of modified coatings is reduced by 80% compared to the pristine. The variation of atomic bond strength of modified coatings is realized. The electrical resistance (77%), microhardness (4.3%), roughness (4.5 times) and pore size are enhanced on the nitrogen implanted coatings. Superhydrophilic surface is turned to hydrophobic on implantation. At higher fluence (1 x 10(17) ions/cm(2)) depicted an enhanced corrosion potential compared to the other coatings. Thus, the new insight on modified coatings is elucidated by correlating phase-structure, surface and corrosion resistance.

Measurements of the laminar burning velocities and NO concentrations in neat and blended ethanol and n-heptane flames

Adiabatic laminar burning velocities and post-flame NO mole fractions for neat and blended ethanol and n-heptane premixed flames were experimentally determined using a heat flux burner and laser-induced fluorescence. The flames were stabilized at atmospheric pressure and at an initial temperature of 338 K, over equivalence ratios ranging from 0.6 to 1.5. These experiments are essential for the development, validation and optimization of chemical kinetic models, e.g. for the combustion of gasoline-ethanol fuel mixtures. It was observed that the addition of ethanol to n-heptane leads to an increase in laminar burning velocity that is not proportional to the ethanol content and to a decrease of NO formation. Such a NO reduction is due to the slightly lower flame temperatures of ethanol, which decrease the production of thermal-NO at 0.6 < Phi < 1.2, while under fuel-rich conditions this behavior is due to the lower concentrations of CH radicals, which decrease the production of prompt-NO. At Phi > 1.3, the lower NO formation through the prompt mechanism in the ethanol flames is partially offset by a lower rate of NO consumption through the reburning mechanism. New experimental results were compared with predictions of the POLIMI detailed chemical kinetic mechanism. An excellent agreement between measurements and simulated results was observed for the laminar burning velocities over the equivalence ratio range investigated; however, discrepancies were found for the NO mole fractions, especially under rich conditions. Further numerical analyses were performed to identify the main causes of the observed differences. Differences found at close-to stoichiometric conditions were attributed to an uncertainty in the thermal-NO mechanism. In addition, disagreement under rich conditions could be explained by the relative importance of reactions in hydrogen cyanide consumption pathways.

Effect of Incentives for Alcohol Abstinence in Partnership With 3 American Indian and Alaska Native Communities A Randomized Clinical Trial

IMPORTANCE Many American Indian and Alaska Native communities are disproportionately affected by problems with alcohol use and seek culturally appropriate and effective interventions for individuals with alcohol use disorders. OBJECTIVE To determine whether a culturally tailored contingency management intervention, in which incentives were offered for biologically verified alcohol abstinence, resulted in increased abstinence among American Indian and Alaska Native adults. This study hypothesized that adults assigned to receive a contingency management intervention would have higher levels of alcohol abstinence than those assigned to the control condition. DESIGN, SETTING, AND PARTICIPANTS This multisite randomized clinical trial, the Helping Our Native Ongoing Recovery (HONOR) study, included a 1-month observation period before randomization and a 3-month intervention period. The study was conducted at 3 American Indian and Alaska Native health care organizations located in Alaska, the Pacific Northwest, and the Northern Plains from October 10, 2014, to September 2, 2019. Recruitment occurred between October 10, 2014, and February 20, 2019. Eligible participants were American Indian or Alaska Native adults who had 1 or more days of high alcohol-use episodes within the last 30 days and a current diagnosis of alcohol dependence. Data were analyzed from February 1 to April 29, 2020. INTERVENTIONS Participants received treatment as usual and were randomized to either the contingency management group, in which individuals received 12 weeks of incentives for submitting a urine sample indicating alcohol abstinence, or the control group, in which individuals received 12 weeks of incentives for submitting a urine sample without the requirement of alcohol abstinence. Regression models fit with generalized estimating equations were used to assess differences in abstinence during the intervention period. MAIN OUTCOMES AND MEASURES Alcohol-negative ethyl glucuronide (EtG) urine test result (defined as EtG<150 ng/mL). RESULTS Among 1003 adults screened for eligibility, 400 individuals met the initial criteria. Of those, 158 individuals (39.5%; mean [SD] age, 42.1 [11.4] years; 83 men [52.5%]) met the criteria for randomization, which required submission of 4 or more urine samples and 1 alcohol-positive urine test result during the observation period before randomization. A total of 75 participants (47.5%) were randomized to the contingency management group, and 83 participants (52.5%) were randomized to the control group. At 16 weeks, the number who submitted an alcohol-negative urine sample was 19 (59.4%) in the intervention group vs 18 (38.3%) in the control group. Participants randomized to the contingency management group had a higher likelihood of submitting an alcohol-negative urine sample (averaged over time) compared with those randomized to the control group (odds ratio, 1.70; 95% CI, 1.05-2.76; P = .03). CONCLUSIONS AND RELEVANCE The study's findings indicate that contingency management may be an effective strategy for increasing alcohol abstinence and a tool that can be used by American Indian and Alaska Native communities for the treatment of individuals with alcohol use disorders.

Sirtuin 6 ameliorates alcohol-induced liver injury by reducing endoplasmic reticulum stress in mice

Alcoholic liver disease (ALD) occurs as a result of chronic and excessive alcohol consumption. It encompasses a wide spectrum of chronic liver abnormalities that range from steatosis to alcoholic hepatitis, progressive fibrosis and cirrhosis. Endoplasmic reticulum (ER) stress induced by ethanol metabolism in hepatocytes has been established as an important contributor to the pathogenesis of ALD. However, whether SIRT6 exerts regulatory effects on ethanol-induced ER stress and contributes to the pathogenesis of ALD is unclear. In this study, we developed and characterized Sirt6 hepatocyte-specific knockout and transgenic mouse models that were treated with chronic-plus-binge ethanol feeding. We observed that hepatic Sirt6 deficiency led to exacerbated ethanol-induced liver injury and aggravated hepatic ER stress. Tauroursodeoxycholic acid (TUDCA) treatment remarkably attenuated ethanol-induced ER stress and ameliorated ALD pathologies caused by Sirt6 ablation. Reciprocally, SIRT6 hepatocyte-specific transgenic mice exhibited reduced ER stress and ameliorated liver injury caused by ethanol exposure. Consistently, knockdown of Sirt6 elevated the expression of ER stress related genes in primary hepatocytes treated with ethanol, whereas overexpression of SIRT6 reduced their expression, indicating SIRT6 regulates ethanol-induced hepatic ER stress in a cell autonomous manner. Collectively, our results suggest that SIRT6 is a positive regulator of ethanol-induced ER stress in the liver and protects against ALD by relieving ER stress. (C) 2021 Elsevier Inc.

Enhanced biodiesel production from oleic acid using TiO2-decorated magnetic ZIF-8 nanocomposite catalyst and its utilization for used frying oil conversion to valuable product

In this study, a new recyclable TiO2-decorated magnetic ZIF-8 (Fe3O4@ZIF-8/TiO2) nanocomposite catalyst was first synthesized and its structural and morphological properties were characterized through different techniques such as XRD, FT-IR, TEM, EDX, TPD, and VSM. Then, biodiesel was produced using the Fe3O4@ZIF-8/TiO2 catalyst through the esterification of oleic acid in the presence of ethanol. Response surface methodology (RSM) was also employed to achieve the optimum experimental operating variables affecting the yield of biodiesel production. Significant variables like the amount of catalyst, the molar ratio of alcohol to fatty acid, reaction time, and temperature were optimized through RSM to achieve the highest yield of biodeisel production. The results indicated that the highest biodiesel yield is obtained at the reaction temperature of 50 degrees C, the reaction time of 62.5 min, the alcohol to oleic acid molar ratio 30:1, and 0.2 g (6 %wt) amount of catalyst. In this condition, the highest yield of biodiesel production was found 80% and 93% using ethanol and methanol, respectively; around 40% higher than pristine TiO2 and magnetic ZIF-8. Subsequently, the biodiesel production in optimum conditions was evaluated from frying oil by using the as-prepared catalyst. The result from H-1 NMR and GC-MS analyses confirmed the efficient conversion of frying oil wastes to valuable biofuel product.

Synthetic Route of 124-76-5, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 124-76-5 is helpful to your research.

Cannabis and crash risk among older drivers

The purpose of this research was to reanalyze data collected from the National Highway Traffic Safety Administration’s Drug and Alcohol Crash Risk Study to investigate whether driving under the influence of cannabis (THC-positive) was associated with elevated crash risk for younger and older drivers. The data came from a case-control relative risk study collected from Virginia Beach, VA, over a 20-month period. Data collectors gathered driver information from the scene of vehicle crashes and, in some cases, from hospitals. Non-crash controls were sampled from the same locations, days, and times as crashes. Key data items included driver demographics and oral fluid and blood samples, which were assayed for licit and illicit drugs. We found no overall association between cannabis use and risk of crash involvement. However, when age and age(2) were allowed to interact with THC, significant interaction effects emerged. THC was associated with increased risk of crash involvement for older drivers. Difference between THC-positive and sober drivers emerged as significant at age 64. The research underscores the value of examining drugged driving in the context of driver age. Age-related declines in neurocognitive and psychomotor functioning were not measured but might be important in explaining the results.
