The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature. 3068-00-6, Name is 1,2,4-Butanetriol, SMILES is OCC(O)CCO, in an article , author is Hosseini, Seyed Fakhreddin, once mentioned of 3068-00-6, Name: 1,2,4-Butanetriol.

Biofunctional quadripartite films were developed by adding trans-Cinnamaldehyde (CIN) (0.4, 0.8, and 1.6% w/v) into chitosan (CH)/poly(vinyl alcohol) (PVA)/fish gelatin (FG) matrices. Rheological data revealed that all solutions exhibited shear-thinning and typical entangle polymers solutions behavior. Mechanical results showed that the incorporation of CIN caused a significant increase (p < 0.05) in tensile strength, while a significant decrease was observed in elongation-at-break. With increasing CIN content, the WVP of the films, which were in the range of 0.785-0.995 g mm/kPa h m(2), increased to some extent, whereas the water solubility and water absorption were reduced up to 47 and 87%, respectively. Moreover, water contact angle analysis showed that the inclusion of CIN made the quadripartite film more hydrophobic, in which the highest value achieved was 86.6 +/- 0.75 degrees at theta(t=10). ATR/FT-IR spectroscopy demonstrated the formation of Schiff-base and intermolecular hydrogen bonds between components' functional groups, which enhanced the quadripartite films' thermal stability and mechanical properties. X-ray diffraction analysis suggested compatibility among the components, and changes of the surface of the films were confirmed by SEM and AFM analyses. Likewise, the antimicrobial activity of the CIN-loaded films were proved against Staphylococcus aureus, Listeria monocytogenes, Salmonella enteritidis, and Escherichia coli. The quadripartite films exhibited in vitro DPPH radical scavenging activity (similar to 35.8%) and ferric reducing power at the maximum CIN testing concentration. The findings of this study proved that CIN-doped films could be used as promising inner functional packaging for food products. Interested yet?

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.

Free fatty acids responsible for characteristic aroma in various sauced-ducks

To investigate the effects of various duck sources on the lipid oxidation and aroma flavor of sauced-ducks, Mallard (ML), Sheldrake (SD), Muscovy (MC), and Cherry-Valley (CV) ducks were used in sauced-duck processing. The results showed significantly different thiobarbituric acid reactive substances (TBARS) values of the four samples (SD 0.05), while the contents of unsaturated fatty acids (UFAs) were ML SD/CV > MC (p < 0.05). Altogether, 105 volatile flavor compounds were detected in sauced-ducks, including acids, alcohols, aldehydes, ketones, esters, hydrocarbons, furans, nitrogen compounds, and others. The volatile compounds were observed differentially composed in the four products, and nineteen potential characteristic biomarkers were explored. The correlation analysis indicated that the characteristic aroma flavor of sauced ducks were significantly associated with specific free fatty acids. These information are useful for learning aroma formation and meat selection and identification in duck products. 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 3068-00-6 help many people in the next few years. Recommanded Product: 1,2,4-Butanetriol.

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.

3-Hydroxytyrosol regulates biofilm growth in Cunninghamella elegans

In contrast to yeast biofilms, those of filamentous fungi are relatively poorly understood, in particular with respect to their regulation. Cunninghamella elegans is a filamentous fungus that is of biotechnological interest as it catabolises drugs and other xenobiotics in an analogous manner to animals; furthermore, it can grow as a biofilm enabling repeated batch biotransformations. Precisely how the fungus switches from planktonic to biofilm growth is unknown and the aim of this study was to shed light on the possible mechanism of biofilm regulation. In dimorphic yeasts, alcohols such as tyrosol and 2-phenylethanol are known to control the yeast-to-hypha switch, and a similar molecule might be involved in regulating biofilm in C. elegans. Gas chromatography-mass spectrometry analysis of crude ethyl acetate extracts from supernatants of 72 h planktonic and biofilm cultures revealed 3hydroxytyrosol as a prominent metabolite. Further quantification revealed that the amounts of the compound in planktonic cultures were substantially higher (>10-fold) than in biofilm cultures. In the presence of exogenous 3-hydroxytyrosol the growth of aerial mycelium was inhibited, and there was selective inhibition of biofilm when it was added to culture medium. There was no biotransformation of the compound when it was added to 72 h-old cultures, in contrast to the related compounds tyrosol and 2-phenylethanol, which were oxidised to a number of products. Therefore, we propose that 3hydroxytyrosol is a new signalling molecule in fungi, which regulates biofilm growth. (C) 2020 The Author(s).

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.
