Preparation of Natural Rubber Composites with High Silica Contents Using a Wet Mixing Process was written by Phumnok, Ekaroek;Khongprom, Parinya;Ratanawilai, Sukritthira. And the article was included in ACS Omega in 2022.Application of 111-46-6 This article mentions the following:

A wet mixing process is proposed for filled rubber composites with a high silica loading to overcome the drawbacks of high energy consumption and workplace contamination of the conventional dry mixing process. Ball milling was adopted for preparing the silica dispersion because it has a simple structure, is easy to operate, and is a low-cost process that can be easily scaled up for industrial production The response surface methodol. was used to optimize the making of the silica dispersion. The optimum conditions for a well-dispersed silica suspension with the smallest silica particle size of 4.9 mm were an about 22% silica content and 62 h of ball milling. The effects of dry and wet mixing methods on the properties of silica-filled rubber composites were investigated in a broad range of silica levels from low to high loadings. The mixing method choice had little impact on the properties of rubber composites with low silica loadings. The silica-filled rubber demonstrated in this study, however, shows superior characteristics over the rubber composite prepared with conventional dry mixing, particularly with high silica loadings. When compared to silica-filled natural rubbers prepared by dry mixing (dry silica rubber, DSR), the wet mixing (for WSR) produced smaller silica aggregates with better dispersion. Due to the shorter heat history, the WSR exhibits superior curing characteristics such as a longer scorch time (2.2-3.3 min for WSR and 1.0-2.1 min for DSR) and curing time (4.1-4.5 min for WSR and 2.2-3.1 min for DSR). Addnl., the WSR has superior mech. properties (hardness, modulus, tensile strength, and especially the elongation at break (420-680% for WSR and 360-620% DSR)) over the DSR. The rolling resistance of WSR is lower than that of DSR. However, the reversed trend on the wet skid resistance is observed In the experiment, the researchers used many compounds, for example, 2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6Application of 111-46-6).

2,2′-Oxybis(ethan-1-ol) (cas: 111-46-6) belongs to alcohols. Because alcohols are easily synthesized and easily transformed into other compounds, they serve as important intermediates in organic synthesis. Tertiary alcohols cannot be oxidized at all without breaking carbon-carbon bonds, whereas primary alcohols can be oxidized to aldehydes or further oxidized to carboxylic acids.Application of 111-46-6

The synthesis of soluble and volatile bioactive compounds by selected brewer鈥瞫 yeasts: Antagonistic effect against enteropathogenic bacteria and food spoiler – toxigenic Aspergillus sp. was written by Sampaolesi, Sofia;Briand, Laura E.;De Antoni, Graciela;Leon Pelaez, Angela. And the article was included in Food Chemistry: X in 2022.Synthetic Route of C4H10O4 This article mentions the following:

Contamination by Aspergillus sp. and the accumulation of its mycotoxins in food and beverages have a high impact on human health and food safety. This investigation inquires the ability of brewer鈥瞫 yeasts discarded after fermentation (brewing fermentation residue, BFR) to synthesize bioactive compounds and to biocontrol Aspergillus sp. BFRs of Saccharomyces cerevisiae MBELGA62 and Pichia kudriavzevii MBELGA61 proved to have bacteriostatic properties and to be efficient in fungal growth reduction, decreasing the growth rate of Aspergillus flavus and Aspergillus parasiticus up to 37.8% and 42.5%, resp. Fungal mycelium degradation along with absentia of conidia was detected near the yeast inoculum. Moreover, the yeasts synthesize volatile bioactive compounds that extend Aspergillus sp. lag phase above 100% and decrease fungal growth rates from 20% towards 44%, along with the complete inhibition of conidia synthesis. These results indicate the potential of this residue to be used in biocontrol applications in the food industry. In the experiment, the researchers used many compounds, for example, (2R,3S)-rel-Butane-1,2,3,4-tetraol (cas: 149-32-6Synthetic Route of C4H10O4).

Analyzing the Effect of Strigolactones on the Motility Behavior of Rhizobia was written by Bernabeu-Roda, Lydia M.;Lopez-Raez, Juan Antonio;Soto, Maria J.. And the article was included in Methods in Molecular Biology (New York, NY, United States) in 2021.Recommanded Product: Calcium (R)-3-(2,4-dihydroxy-3,3-dimethylbutanamido)propanoate This article mentions the following:

In the Rhizobium-legume symbiosis, strigolactones (SLs) promote root nodule formation; however, the exact mechanism underlying this pos. effect remains unknown. The recent finding that an SL receptor legume mutant shows a wild-type nodulation phenotype suggests that SLs influence the symbiosis by acting on the bacterial partner. In agreement with this, the application of the synthetic SL analog GR24 on the alfalfa symbiont Sinorhizobium (Ensifer) meliloti has been shown to stimulate swarming, a specialized bacterial surface motility, which could influence infection of legumes by Rhizobia. Surface motility assays for many bacteria, and particularly for Rhizobia, are challenging. The establishment of protocols to study bacterial surface motility is key to decipher the role of SLs as rhizosphere cues for rhizobacteria. In this chapter, we describe a set of protocols implemented to study the different types of motility exhibited by S. meliloti. In the experiment, the researchers used many compounds, for example, Calcium (R)-3-(2,4-dihydroxy-3,3-dimethylbutanamido)propanoate (cas: 137-08-6Recommanded Product: Calcium (R)-3-(2,4-dihydroxy-3,3-dimethylbutanamido)propanoate).

Calcium (R)-3-(2,4-dihydroxy-3,3-dimethylbutanamido)propanoate (cas: 137-08-6) belongs to alcohols. The oxygen atom of the strongly polarized O鈥旽 bond of an alcohol pulls electron density away from the hydrogen atom. This polarized hydrogen, which bears a partial positive charge, can form a hydrogen bond with a pair of nonbonding electrons on another oxygen atom. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.Recommanded Product: Calcium (R)-3-(2,4-dihydroxy-3,3-dimethylbutanamido)propanoate

The findings of theor. data indicated that the calculated results are in accordance with the exptl. findings. Moreover, the catalytic efficiencies of both complexes were investigated by oxidizing the benzylic alcs. in the presence of urea hydrogen peroxide (UHP) in acetonitrile.

Cutting root treatment combined with low-temperature storage regimes on non-volatile and volatile compounds of Oudemansiella raphanipes was written by Xia, Rongrong;Wang, Zicheng;Xu, Heran;Hou, Zhenshan;Li, Yunting;Wang, Yafei;Feng, Yao;Zhang, Xiang;Xin, Guang. And the article was included in LWT–Food Science and Technology in 2022.Reference of 3391-86-4 This article mentions the following:

Oudemansiella raphanipes (O. raphanipes) has recently been gaining popularity due to its active and flavor compounds In this study, the profiles of phenolics, flavonoids, non-volatile and volatile compounds of fresh O. raphanipes were subjected to cutting root (CR) and pulling root (PR) harvesting methods during different storage temperatures (5掳C and 20掳C) were investigated. The results showed that CR treatment effectively increased phenolic and flavonoid contents, maintained the sensory scores and the umami value based on e-tongue, increased more C8 volatile contents, and inhibited off-flavor acids production during 5掳C storage. The EUC values of the fresh O. raphanipes ranged from 4.72 to 23.66 g monosodium glutamate (MSG) 100 g-1, which TAVs were at a relatively high level in CR treatment than in PR treatment. A two-way anal. of variance (ANOVA) and principal component anal. (PCA) revealed statistically significant differences in different harvesting methods that affected the mushroom flavor. Eleven components were screened as taste characteristics contributors by partial least squares regression model (PLS-R) anal., including Glu, umami nucleotides, and 1-octene-3-ol and 3-octanone. Thus, the cutting root treatment is a promising method for obtaining the high flavor quality of fresh O. raphanipes during cooling storage. In the experiment, the researchers used many compounds, for example, Oct-1-en-3-ol (cas: 3391-86-4Reference of 3391-86-4).

Oct-1-en-3-ol (cas: 3391-86-4) belongs to alcohols. Alcohols are among the most common organic compounds.
