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.

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.

Processes of structure formation and paste matrix hydration with multilayer carbon nanotubes additives

The creation of high-strength materials with targeted structure formation and hydration to obtain building composites with a given set of properties represents a relevant area of the modern construction sector. This paper investigates promising nanomodifying additives i.e. multilayer carbon nanotubes along with an effective method to obtain a comprehensive nanomodifying additive through pre-ultrasonic dispersion of MWCNT globules of varying dispersive capacity in an isopropyl alcohol medium. The comprehensive nanomodifying additive obtained is characterized by high stability as well as a uniform distribution of carbon nanotubes in the additive. The Structure software package developed by the authors was used to study the structure of paste matrix at the mesastructural level. The modification of paste matrix by means of the developed comprehensive nanostructure additive reduces the crack length index to 113% with the crack length ratio and the crack shape ratio going down to 61% and 34%, respectively. The increase in the strength and durability of the compositions modified by the developed comprehensive nanomodifying additive is due to a more complete filling of the intergranular void with newly formed structures in the form of C-S-H (I), tobermorite and gel phases which enhance the degree of packing and density of the composite under examination. However, the share of nano – and micropores goes up by 1.21 and 1.31 times, respectively, while the share of meso – and macropores decreases by 1.51 and 5.25 times.

Transcriptional regulation of alcohol induced liver fibrosis in a translational porcine hepatocellular carcinoma model

Hepatocellular carcinoma (HCC) is the 5th most common and 2nd deadliest cancer worldwide. HCC risk factors include alcohol induced liver cirrhosis, which prompts hepatic inflammation, cell necrosis, and fibrosis deposition. As 25% of HCC cases are associated with alcohol induced liver disease, understanding the effects of the cirrhotic liver microenvironment on HCC tumor biology and therapeutic responses are critical. This study utilized the Oncopig Cancer Model-a transgenic pig model that recapitulates human HCC through induced expression of KRAS(G12D) and TP53(R167H )driver mutations-to investigate the molecular mechanisms underlying alcohol induced liver disease. Oncopigs (n = 5) underwent fibrosis induction via infusion of ethanol and ethiodized oil (1:3 v/v dosed at 0.75 mL/kg) into the hepatic arterial circulation. Eight-weeks post induction, liver tissue samples from fibrotic and age-matched control (n = 5) Oncopigs were collected for histological evaluation and transcriptional profiling. Increased hepatic inflammation and fibrosis was observed in fibrotic Oncopigs via pathological assessment. Transcriptional profiling (RNA-seq) resulted in the identification of 4387 differentially expressed genes between Oncopig fibrotic and control livers. GO term enrichment analysis identified pathway alterations associated with cirrhosis progression in humans, including cell proliferation, angiogenesis, extracellular matrix deposition, and oxidation-reduction. Key alterations include activation of hepatic stellate cells, increased matrix metalloproteinase production, and altered expression of ABC and SLC transporter genes involved in transport of anticancer drugs.These results demonstrate Oncopig liver fibrosis recapitulates transcriptional hallmarks of human cirrhosis, making the Oncopig an ideal model for studying the effects of the cirrhotic liver microenvironment on HCC tumor biology and therapeutic response.

Biotransformation of spent coffee grounds by fermentation with monocultures of Saccharomyces cerevisiae and Lachancea thermotolerans aided by yeast extracts

Spent coffee grounds (SCG) is a low-value solid food waste generated from the rising consumption of coffee. There is a need to transform the huge amount of SCG to value-added products such as alcoholic beverages. In this study, monocultures of Saccharomyces cerevisiae Merit and Lachancea thermotolerans Concerto were used to ferment SCG hydrolysates supplemented with yeast extracts. The addition of yeast extracts slightly enhanced the growth of both S. cerevisiae Merit and L. thermotolerans Concerto. In addition, the yeast extracts also increased the production of organic acids (e.g. succinic acid and acetic acid) and volatiles such as 2-phenylethyl alcohol and ethyl esters (e.g. ethyl octanoate and ethyl 2,4-hexadienoate). Furthermore, the supplementation of yeast extracts showed a more significant effect on the performance (e.g. yeast growth) of S. cerevisiae Merit than that on L. thermotolerans Concerto. Our results indicated that the addition of yeast extracts may provide a new strategy to enhance the transformation of SCG into a potential alcoholic beverage with flavor compound complexity.

Numerical and experimental evaluation on the pooled effect of waste cooking oil biodiesel/diesel blends and exhaust gas recirculation in a twin-cylinder diesel engine

Nowadays, worldwide, many countries are engaged in reducing the vehicular exhaust emissions from diesel engines as diesel engines are the main source of power in various transport applications. Biofuels obtained from various feedstocks serve as a better alternative fuel in CI engines because of its emission reducing capabilities. The major drawback in the usage of biofuels in CI engine is the rise in the formation of nitrogen oxides which would be harmful to human health. WCO biofuel was processed using trans-esterification technique and the contents available were analyzed using gas chromatography mass .spectroscopy (GCMS). Four different blends, namly B100, B60, B40, and B20 were made. The physio-chemical properties of the prepared test fuels were identified using ASTM standards. The investigation on the characterisation of performance, combustion, sound and emission of the test engine was done. Fuel combustion modeling was done using ANSYS Fluent for diesel, WCO biofuel and best suited blend obtained from experimental results. From both the simulated and the experimental results, it was found that B20 blend fuel would be best suited to the test engine with a maximum reduction of 17% in unburned hydrocarbon (HC), 30% in carbonmonooxide (CO), 14.08% in smoke, 7.35% in carbondioxide (CO2) and 16.46% increase in NOx emission respectively. With an intention to reduce NOx emission in the selected B20 blend fuel, EGR at three rates, namely (5%, 10%, and 15%) were utilized. Again, the experiments were conducted with varying EGR rates for B20 blend fuel. A good percentage of reduction in NOx was obtained with increase in EGR rates. But other emissions like CO, HC, smoke, and CO2 emissions were found to increase with rise in EGR rates. Thus, a comparison was made with three rates of EGR emission values with all types of test fuels to optimize the EGR rate leading into the inlet charge. 10% EGR rate gave a maximum reduction of 16.34% in NOx emission without affecting much in the emissions like HC, CO, Smoke, and CO2 along with a small drop in performance.

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.

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.

Synthesis and electrochemical properties of V(2)O(5)(center dot)nH(2)O compound with reduced graphene oxide/polyvinyl alcohol film as the free-standing cathode for coin-typed aqueous Zn-ion batteries

Recently aqueous zinc-ion batteries (AZIBs) have been widely studied on the aspects of electrode materials and electrolytes, but it is still far from practical application. The limitation of AZIBs is that it is difficult to have both high specific capacity and good cycle stability. Herein, a free-standing cathode V(2)O(5)(center dot)nH(2)O/reduced graphene oxide-polyvinyl alcohol (denoted as V(2)O(5)(center dot)nH(2)O/rGO-PVA) film was synthesized by one-step hydrothermal method and vacuum filtration. As the cathode for the coin-typed AZIBs, the V(2)O(5)(center dot)nH(2)O/rGO-PVA film cathode delivers the ultrahigh capacity of 553 mA h g(-1) at the current density of 0.1 A g(-1). And the capacity is 194 mA h g(-1) at 0.5 A g(-1), after 300 cycles, it still remains 152 mA h g(-1). At the power density of 183 W.kg(-1), the high energy density is calculated as 354 Wh.kg(-1) based on the mass of the cathode. The energy storage mechanism was studied by some ex-situ characterizations as well. This work not only proposes a strategy for the synthesis of V(2)O(5)(center dot)nH(2)O/rGO-PVA film, but also demonstrates that the as-obtained free-standing cathode is beneficial to the assembly of coin-typed AZIBs and exhibits excellent electrochemical performance.

Using power ultrasound to release glycosidically bound volatiles from orange juice: A new method

Acid hydrolysis and enzymatic hydrolysis are the main methods for releasing glycosidically bound volatiles (GBV). However, acid hydrolysis yields a strong pungent odor, and enzymatic hydrolysis is time consuming. In the present study, a new method, ultrasound hydrolysis, is reported to release GBV. This method is simple, environmentally friendly, fast and effective. Large differences were observed in the released aglycones and glycosyls between ultrasound and enzymatic hydrolysis of GBV. More types of aglycones were released under ultrasound than enzymatic hydrolysis. Alcohols and esters were the main aglycones under enzymatic hydrolysis, and terpenoids, esters and aldehydes were the main aglycones under ultrasound hydrolysis. The glycosyls released under ultrasound hydrolysis were mannose, glucose and sucrose, and those released under enzymatic hydrolysis were galactose and sucrose. The present study gives a new insight into a hydrolytic method for GBV by using ultrasound hydrolysis and can provide a reference method for fruit juice aromatization.
