Influence of calophyllum inophyllum and Jojoba oil methyl ester blended with n-pentanol additive upon overall performance, combustion and emission characteristics of a TDI engine operated in natural aspirated mode

The present manuscript briefly elaborates the performance, combustion and emission behaviour of a turbocharged direct injection diesel engine operated in dual mode where calophyllum inophyllum and Jojoba oil methyl ester are the injected fuel while in second case the above said test fuel blends were mixed homogeneously with n-pentanol that acts as an additive during the experimentation. The main objective of using n-pentanol is its five straight chain carbon atoms that has better possibility of homogeneous blending with biodiesel blends due to its high cetane number, stability and density in contrast to other alcohol based additives helping in improving engine performance and diminished exhaust emissions. During the experimentation, engine parameters like compression ratio (17.5:1), injection timing (21 degrees bTDC), injector opening pressure (220 bar), speed (1500 rpm) were kept constant. Results concluded CIME20-P20 blend to be reliable and potential alternative fuel to partially replace conventional diesel fuel. Considering performance and emission characteristics calophyllum inophyllum oil methyl ester and pentanol blend (CIME20-P20) depicts a higher brake specific fuel consumption of 3.41% while lower exhaust gas temperature and brake thermal efficiency of 13.46% and 1.18% in contrast to diesel fuel. Moving on to emission analysis, carbon dioxide, hydrocarbon, oxides of nitrogen and smoke opacity for CIME20-P20 were 57.02%, 59.37%, 17.39% and 41.53% lower than conventional diesel fuel. Hence, coming to the overall summary, CIME20-P20 depicts better performance and diminished exhaust emission thereby making it more potential to substitute the conventional fuel without any engine alteration for better environmental sustainability and energy security.

Elevated Lithium Ion Regulation by a Natural Silk Modified Separator for High-Performance Lithium Metal Anode

Metallic lithium anode has long stood as the holy grail in the field of secondary batteries for its high theoretical specific capacity and low electrochemical potential. But its edge is blunted by the inherent uncontrolled lithium dendrite growth that can curtail the cycle life and raise safety concerns. In this work, a functional modification layer from a derivant of natural silk is developed to protect lithium anode via a facile automatic transfer route. Via offering abundant functional group sites, the Li-ion flux on the anode surface is made uniform efficiently. The silk fibroin-based modification layer also contributes to the in situ formation of a Li3N-rich solid electrolyte interphase film on the lithium anode. Consequently, a high-performance lithium metal anode with dendrite-free morphology and significantly enhanced cycle stability is achieved: when paired with LiFePO4 cathodes, the full cell achieves a long-term cycling stability of 3000 cycles at 5 C; when paired with sulfur cathodes (5 mg(sulfur) cm(-2)), a long lifespan for over 400 cycles at 1 C is achieved. This work offers a facile and practical approach for the interface modification of the high-performance lithium anode and as well as provides a new perspective for the application of biomass-based materials in advanced batteries.

Alcohol consumption and risk of stomach cancer: A meta-analysis

Stomach cancer is one of the most common cancers in the world. The relationship between alcohol consumption and the risk of stomach cancer remains unclear. Epidemiology studies investigating this relationship have shown inconsistent findings. A meta-analysis was performed to explore the association between alcohol consumption and increased stomach cancer risk. Eighty-one epidemiology studies, including 68 case-control studies and 13 cohort studies, were included in this study. A significant association was found between alcohol consumption and increased risk of stomach cancer (OR = 1.20, 95% CI 1.12-1.27). To explore the source of the significant heterogeneity (p < 0.05, I-2 = 86%), analysis was stratified by study type (case-control study and cohort study), control type (hospital-based control and population-based control), gender (male, female, and mix), race (White and Asian), region (United States, Sweden, China, Japan), subsite of stomach cancer, and type of alcohol. The stratified analyses found that region and cancer subsite are major sources of the high heterogeneity. The inconsistent results in different regions and different subsites might be related to smoking rates, Helicobacter pylori infection, obesity, and potential genetic susceptibility. The positive association between drinking and increased risk of stomach cancer is consistent in stratified analyses. The dose-response analysis showed a clear trend that a higher daily intake of alcohol is associated with a higher risk of stomach cancer. The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

Total Synthesis of Mycinolide IV and Path-Scouting for Aldgamycin N

Proof-of-concept is provided that a large estate of 16-membered macrolide antibiotics can be reached by a unified approach. The key building block was formed on scale by an asymmetric vinylogous Mukaiyama aldol reaction; its alkene terminus was then converted either into the corresponding methyl ketone by Wacker oxidation or into a chain-extended aldehyde by catalyst-controlled branch-selective asymmetric hydroformylation. These transformations ultimately opened access to two structurally distinct series of macrolide targets. Notable late-stage maneuvers comprise a rare example of a ruthenium-catalyzed redox isomerization of an 1,3-enyne-5-ol into a 1,3-diene-5-one derivative, as well as the elaboration of a tertiary propargylic alcohol into an acyloin by trans-hydrostannation/Chan-Lam-type coupling. Moreover, this case study illustrates the underutilized possibility of forging complex macrolactone rings by transesterification under essentially neutral conditions.

Ecological Momentary Assessment of Alcohol Consumption and Its Concordance with Transdermal Alcohol Detection and Timeline Follow-Back Self-report Among Adults Experiencing Homelessness

Background Studies of alcohol use presume valid assessment measures. To evaluate this presumption, we examined the concordance of alcohol use as measured by ecological momentary assessment (EMA) self-reports, transdermal alcohol concentration readings via the Secure Continuous Remote Alcohol Monitor (SCRAM), and retrospective self-reports via the Timeline Follow-Back (TLFB) among adults experiencing homelessness. Methods Forty-nine adults who reported alcohol misuse (mean age = 47, SD = 9; 57% Black; 82% men) were recruited from a homeless shelter. For 4 weeks, alcohol use was assessed: (i) 5 times or more per day by EMA, (ii) every 30 minutes by a SCRAM device worn on the ankle, and (iii) by TLFB for the past month at the end of the study period. There were 1,389 days of observations of alcohol use and alcohol use intensity for 49 participants. Results EMA and SCRAM alcohol use data agreed on 73% of days, with an interrater agreement Kappa = 0.46. A multilevel analysis of concordance of 3 measures for alcohol use yielded statistically significant correlations of 0.40 (day level) and 0.63 (person level) between EMA and SCRAM. Alcohol use was detected on 49, 38, and 33% of days by EMA, SCRAM, and TLFB, respectively. For alcohol use intensity, EMA and SCRAM resulted in statistically significant correlations of 0.46 (day level) and 0.78 (person level). The concordance of TLFB with either EMA or SCRAM was weak, especially at the day level. Conclusions This is the first study to examine concordance of alcohol use estimates using EMA, SCRAM, and TLFB methods in adults experiencing homelessness. EMA is a valid approach to quantifying alcohol use, especially given its relatively low cost, low participant burden, and ease of use. Furthermore, any stigma associated with wearing the SCRAM or reporting alcohol use in person may be attenuated by using EMA, which may be appealing for use in studies of stigmatized and underserved populations.

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.

Theoretical study of heat transfer enhancement mechanism of high alcohol surfactant in spray cooling

High alcohol surfactant could enhance spray cooling heat transfer, however the enhancing mechanism had not been identified. The present work used numerical model of spray cooling for high alcohol surfactant to specify the mechanism. After adding high alcohol surfactant, the spray characteristics and fluid properties were changed. The influences of these factors on heat transfer were studied, and it was found that the enhancement of heat transfer was mainly attributed to the effect of high alcohol surfactant on surface tension and droplet diameter: the decrease of surface tension and increase of droplet diameter made liquid film thicker and faster, and the lager liquid film thickness and velocity were helpful to take away the heat with a better flow. Both parameters were included in Weber number of droplets, and it could be concluded that high alcohol surfactant improved spray cooling performance mainly because of the increased Weber number. The dominant heat transfer mechanism was also discussed in the analysis of the effect of spray flow.

We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 7541-49-3. The above is the message from the blog manager. Quality Control of 3,7,11,15-Tetramethylhexadec-2-en-1-ol.

Electrocatalytic methane oxidation on Co3O4- incorporated ZrO2 nanotube powder

The activation of methane (CH4) gas to produce more valuable liquid hydrocarbons has long been a challenging issue in catalytic research. Electrochemical oxidation is one of the main methods of methane activation and can usually proceed at in ambient temperature. However, the lack of efficient electrocatalysts limits the practical application of this strategy. In this study, ZrO2 nanotube powder with a high specific surface area was decorated with Co3O4 nanoparticles and used as the electrochemical anode for the partial oxidation of methane to generate C3 alcohol products. The Co3O4 nanoparticles formed on outer the surface of the ZrO2 nanotubes offer an accessible diffusion route for methane gas, resulting in a low onset potential for electrochemical methane activation. A high production rate of approximately 2416 mu mol g(cat)(-1) h(-1) was obtained at 1.6 V (vs RHE) after 12 h of reaction. This nanostructure engineering strategy contributes to the enhancement of catalytic activity for electrochemical methane oxidation with the production of higher alcohols, which could provide a new catalyst synthesis strategy for researchers.

Conservation of ‘Palmer’ mango with an edible coating of hydroxypropyl methylcellulose and beeswax

Mango is a tropical fruit presenting intense postharvest metabolism. In storage at room temperature, it presents a short shelf life due to the high respiratory rate, and consequent ripening, which limits the marketing period in distant regions. This study evaluated the effect of edible coatings of hydroxypropyl methylcellulose and beeswax in concentrations of 10, 20, and 40% in ‘Palmer’ mangoes stored for 15 days at 21 degrees C. The coatings controlled ripening, maintaining peel and pulp colors, firmness, soluble solids (SS), titratable acidity (TA), SS/TA ratio, sugars, ascorbic acid, phenolic compounds, flavonoids, beta-carotene, and antioxidant activity. Also, they reduced weight loss, oxidative stress, and the anthracnose (Colletotrichum gloeosporioides) incidence, without inducing alcohol dehydrogenase activity, which suggests that coated fruit did not ferment. Treatment with 20% beeswax was the most suitable for industrial applications, increasing in six days the mangoes shelf life.

Abnormal volatile and normal stable bipolar resistive switching characteristics of hybrid nanocomposites: Morphology-defects-property ‘Relationship

The characteristics of nano-fillers in a polymer matrix have a significant influence on the microstructural, thermo-mechanical, optical, and conductivity properties of organic-inorganic nanocomposites. In this study, we investigated the influence of inorganic component – ZnO nanoparticles (NPs) on the characteristics and properties of PVA-ZnO nanocomposites which have been applied as an insulation layer in a resistive switching (RS) device. Three nanocomposites originating from three different types of ZnO NPs exhibit different RS characteristics: Abnormal volatile RS is observed with the similar to 20-nm-sized spherical-like NPs (Z1) and 15-20-nm-sized mixed shaped NPs (Z2), whereas normal nonvolatile bipolar RS is observed with the 50-150-nm-sized hexagonal rod-like NPs (Z3). The concentration and size of the intrinsic defects of the ZnO NPs as well as the thickness of the PVA-ZnO interface are responsible for the different charge transport paths, operating voltage ranges, and ON/OFF switching ratios of the memory devices. Simultaneously, the distinct sizes and morphologies of the ZnO NPs can affect the nanoholes among the PVA chains and induce various fractional free volumes in the nanocomposites. It may modify the conductivity of the nanocomposite layer or the resistance ratio of the memory devices. Understanding the influence of ZnO NPs size, morphology, and defects on the characteristics of RS of PVA-ZnO nanocomposites can help in the selection and management of functional applications, especially in the data storage field.
