On February 3, 2021, Cao, Jian; Gao, Dejun; Li, Chun; Si, Xiaoqing; Jia, Jianshu; Qi, Junlei published an article.Product Details of 143-10-2 The title of the article was Bioinspired Metal-Intermetallic Laminated Composites for the Fabrication of Superhydrophobic Surfaces with Responsive Wettability. And the article contained the following:

Hundreds of copper and titanium foils were applied to prepare biomimetic metal-intermetallic laminated composites by diffusion bonding. The cross sections of the obtained diffusion bonded bulks were etched selectively with FeCl3 solution to get regular microarray structures. This kind of microstructure was controlled accurately and promptly by simple parameter adjustment. The etched surfaces were modified with 1-dodecanethiol, and the water contact angles (WCAs) were measured. The relationship between the microstructure and wettability of the achieved material was discussed, and the reason for the anisotropic wettability was also analyzed. Then etched surfaces were anodized in different electrolyte solutions to obtain different nanostructures. The morphol. and chem. compositions of the surfaces were analyzed. The surfaces with CuO nanostructures by modification show superhydrophobicity with self-cleaning, on which the WCA and water sliding angle are 160.9° and 0.8°, resp. The surfaces with TiO2 nanostructures without modification show UV light-responsive wettability. After modification with 11-mercaptoundecanoic acid and 1-decanethiol, the surfaces also exhibit pH-responsive wettability. The superhydrophobic surfaces with responsive wettability have potential applications in biotechnol. and microfluidics. The experimental process involved the reaction of 1-Decanethiol(cas: 143-10-2).Product Details of 143-10-2

On January 20, 2022, Lee, Hwanhui; To, Ngoc Bao; Kim, Myeongsun; Nguyen, Yen Thi-Kim; Cho, Somi Kim; Choi, Hyung-Kyoon published an article.Application In Synthesis of 2,3-Dihydroxypropanoic acid The title of the article was Metabolic and lipidomic characterization of radioresistant MDA-MB-231 human breast cancer cells to investigate potential therapeutic targets. And the article contained the following:

To provide preliminary insights into metabolic and lipidomic characteristics in radioresistant triple-neg. breast cancer (TNBC) cells and suggest potential therapeutic targets, we performed a comprehensive metabolic and lipidomic profiling of radioresistant MDA-MB-231 (MDA-MB-231/RR) TNBC cells and their parental cells using gas chromatog.-mass spectrometry and nano electrospray ionization-mass spectrometry, followed by multivariate statistical anal. Buthionine sulfoximine (BSO) and radiation were co-treated to radioresistant TNBC cells. The level of glutathione (GSH) was significantly increased, and the levels of GSH synthesis-related metabolites, such as cysteine, glycine, and glutamine were also increased in MDA-MB-231/RR cells. In contrast, the level of lactic acid was significantly reduced. In addition, reactive oxygen species (ROS) level was decreased in MDA-MB-231/RR cells. In the lipidomic profiles of MDA-MB-231/RR cells, the levels of phosphatidylcholine (PC) and phosphatidylethanolamine (PE) were significantly increased, whereas those of most of the phosphatidylinositol species were significantly decreased. BSO sensitized MDA-MB-231/RR cells to radiotherapy, which resulted in decreased GSH level and increased ROS level and apoptosis. Radioresistant TNBC cells showed distinct metabolic and lipidomic characteristics compared to their parental cells. We suggested activated GSH, PC, and PE biosynthesis pathways as potential targets for treating radioresistant TNBC cells. Particularly, enhanced radiosensitivity was achieved by inhibition of GSH biosynthesis in MDA-MB-231/RR cells. The experimental process involved the reaction of 2,3-Dihydroxypropanoic acid(cas: 473-81-4).Application In Synthesis of 2,3-Dihydroxypropanoic acid

Sillner, Nina; Walker, Alesia; Lucio, Marianna; Maier, Tanja V.; Bazanella, Monika; Rychlik, Michael; Haller, Dirk; Schmitt-Kopplin, Philippe published an article in 2021, the title of the article was Longitudinal profiles of dietary and microbial metabolites in formula- and breastfed infants.Quality Control of 3-Hydroxyphenylacetic acid And the article contains the following content:

The early-life metabolome of the intestinal tract is dynamically influenced by colonization of gut microbiota which in turn is affected by nutrition, i.e. breast milk or formula. A detailed examination of fecal metabolites was performed to investigate the effect of probiotics in formula compared to control formula and breast milk within the first months of life in healthy neonates. A broad metabolomics approach was conceptualized to describe fecal polar and semi-polar metabolites affected by feeding type within the first year of life. Fecal metabolomes were clearly distinct between formula- and breastfed infants, mainly originating from diet and microbial metabolism Unsaturated fatty acids and human milk oligosaccharides were increased in breastfed, whereas Maillard products were found in feces of formula-fed children. Altered microbial metabolism was represented by bile acids and aromatic amino acid metabolites. Elevated levels of sulfated bile acids were detected in stool samples of breastfed infants, whereas secondary bile acids were increased in formula-fed infants. Microbial co-metabolism was supported by significant correlation between chenodeoxycholic or lithocholic acid and members of Clostridia. Fecal metabolites showed strong inter- and intra-individual behavior with features uniquely present in certain infants and at specific time points. Nevertheless, metabolite profiles converged at the end of the first year, coinciding with solid food introduction. The experimental process involved the reaction of 3-Hydroxyphenylacetic acid(cas: 621-37-4).Quality Control of 3-Hydroxyphenylacetic acid

G.; Venema, K.; Tabernero, M.; Sarria, B.; Bravo, L.; Mateos, R. published an article.Recommanded Product: 3-Hydroxyphenylacetic acid The title of the article was Bioconversion of polyphenols and organic acids by gut microbiota of predigested Hibiscus sabdariffa L. calyces and Agave (A. tequilana Weber) fructans assessed in a dynamic in vitro model (TIM-2) of the human colon. And the article contained the following:

The present work aimed at understanding gut microbiota bioconversion of phenolic compounds (PC) and organic acids in predigested Hibiscus sabdariffa (Hb) calyces and the mixture of Hb and Agave (Agave tequilana Weber) fructans (AF). With this purpose, dried Hb and Hb/AF were predigested with enzymic treatment, and then fermented in a dynamic in vitro model of the human colon (TIM-2). After HPLC-ESI-QToF-MS anal. of samples taken at 0, 24, 48 and 72 h of fermentation, it was observed that hydroxycinnamic acids, flavanols, flavonols, and anthocyanins were mainly transformed into derivatives of hydroxyphenylpropionic, hydroxyphenylacetic and hydroxybenzoic acids. Moreover, organic acids, such as hydroxycitric and hibiscus acids, were formed along with unidentified lactones and reduced compounds Interestingly, no differences were observed between microbial-derived metabolites formed after the fermentation of Hb and Hb/AF. In conclusion, colonic fermentation of polyphenol-rich Hb yields a wide range of microbial phenolic metabolites with potential effects on health. The experimental process involved the reaction of 3-Hydroxyphenylacetic acid(cas: 621-37-4).Recommanded Product: 3-Hydroxyphenylacetic acid

On August 5, 2019, Brune, Veronika; Hegemann, Corinna; Mathur, Sanjay published an article.Safety of 2,2′-(tert-Butylazanediyl)diethanol The title of the article was Molecular Routes to Two-Dimensional Metal Dichalcogenides MX2 (M = Mo, W; X = S, Se). And the article contained the following:

New synthetic access to two-dimensional transition metal dichalcogenides (TMDCs) is highly desired to exploit their extraordinary semiconducting and optoelectronic properties for practical applications. We introduce here an entirely novel class of mol. precursors, [MIV(XEtN(Me)EtX)2] (MIV = MoIV, WIV, X = S, Se), enabling chem. vapor deposition of TMDC thin films. Molybdenum and tungsten complexes of dianionic tridentate pincer-type ligands (HXEt)2NR (R = Me, tert-Bu, phenyl) produced air-stable monomeric dichalcogenide complexes, [W(SEtN(Me)EtS)2] and [Mo(SEtN(Me)EtS)2], displaying W and Mo centers in an octahedral environment of 4 S and 2 N donor atoms. Owing to their remarkable volatility and clean thermal decomposition, both Mo and W complexes, when used in the chem. vapor deposition (CVD) process, produced crystalline MoS2 and WS2 thin films. X-ray diffraction anal. and at.-scale imaging confirmed the phase purity and 2D structural characteristics of MoS2 and WS2 films. The new set of ligands presented in this work open ups convenient access to a scalable and precursor-based synthesis of 2D transition metal dichalcogenides. The experimental process involved the reaction of 2,2′-(tert-Butylazanediyl)diethanol(cas: 2160-93-2).Safety of 2,2′-(tert-Butylazanediyl)diethanol

A. published an article.Formula: C9H21N3O3 The title of the article was Preparation of Complexes η4-4-(1,3-Diphenyl-2-propen-1-one)-η3-3-(1,3,5-triorganyl-1,3,5-triazacyclohexane)carbonyltungsten(0) and Their Reactions with Diethyl Phosphite. And the article contained the following:

New W complexes were prepared of a composition η3-[(1,3,5-triorganyl)-1,3,5-triazacyclohexane]tricarbonyltungsten(0) where a tridentate coordination of the triazinane fragment to the metal center was found. The reaction of tricarbonyl triazinane W complexes with 1,3-diphenyl-2-propen-1-one (chalcone) under thermochem. activation resulted in replacement of two CO mols. in the coordination sphere of W by a chalcone mol. linked to the transition metal atom through a system of π-bonds C:C and C:O. The phosphorylation of η4-(1,3-diphenyl-2-propen-1-one)-η3-[(1,3,5-triphenyl)-1,3,5-triazacyclohexane]monocarbonyltungsten(0) with di-Et phosphite occurred at the carbonyl group of the coordinated heterodiene; the phosphonate thus formed underwent intra-complex phosphonate-phosphate rearrangement affording an organometallic phosphate.
