Hollow double-layer CuO microtubes are fabricated by electroless deposition using root hairs of Syngonium podophyllum as biotemplates. It is a new efficient biotemplate for fabricating tubular microstructures because of its reproducible and eco-friendly characteristics. The fabricated microtubes showed unique double-layer structures and the thickness of tubular wall can be adjusted by controlling the deposition time. It was indicated that the microtubes comprised of pure monoclinic CuO with good crystallinity based on XRD and TEM anal.

《Syntheses of diselenide-containing dynamic polymers and their application in polymer alloys》 was written by Liu, Jia; Ma, Xiaoning; Tong, Yanping; Lang, Meidong. Recommanded Product: 627-18-9This research focused ontrimethylenecarbonate polycarbonate diselenidediol initiated blend mech property; caprolactone polyester diselenidediol initiated blend mech property. The article conveys some information:

The diselenide-containing polycarbonate ((PTMCSe)2) and diselenide-containing poly(ε-caprolactone) ((PCLSe)2) were synthesized by the ring opening polymerization using a new compound of di-(1-hydroxypropyl) diselenide ((HOC3H6Se)2) as initiator. The dynamic properties of these diselenide-containing polymers were revealed by diselenide exchange reactions, which could be realized under visible irradiation at room temperature As the result of the diselenide exchange between (PTMCSe)2 and (PCLSe)2, a di-block polymer (PCLSeSePTMC) was formed in (PTMCSe)2/(PCLSe)2 alloy. Taking advantage of the diselenide exchange, the compatibility and miscibility of (PTMCSe)2/(PCLSe)2 alloy was significantly improved by the exchange product (PCLSeSePTMC) which acted as polymeric compatibilizer. This novel concept may be applied in other polymer alloys containing dynamic covalent polymers. In the part of experimental materials, we found many familiar compounds, such as 3-Bromopropan-1-ol(cas: 627-18-9Recommanded Product: 627-18-9)

3-Bromopropan-1-ol(cas: 627-18-9) is used in the synthesis of fluorescent halide-sensitive quinolinium dyes, chiral, quaternary prolines through cyclization of quaternary amino acids and molten salt-polymers.

Computed Properties of C12H20O6On March 14, 2022, Schoch, Silvia; Iacopini, Dalila; Dalla Pozza, Maria; Di Pietro, Sebastiano; Degano, Ilaria; Gasser, Gilles; Di Bussolo, Valeria; Marchetti, Fabio published an article in Organometallics. The article was 《Tethering Carbohydrates to the Vinyliminium Ligand of Antiproliferative Organometallic Diiron Complexes》. The article mentions the following:

Four propargyl O-glycosides derivatized with mannose, glucose, and fructose moieties were synthesized and then incorporated within a diiron structure as part of a vinyliminium ligand. Hence, six glycoconjugated diiron complexes, [2-5]CF3SO3 (see Scheme 1) and the nonglycosylated analogs [6a-b]CF3SO3, were obtained in high yields and unambiguously characterized by elemental anal., mass spectrometry, and IR and multinuclear NMR spectroscopies. All compounds exhibited a significant stability in DMSO-d6/D2O solution, with 63-89% of the complexes unaltered after 72 h at 37° and also in the cell culture medium. The cytotoxicity of [2-6]CF3SO3, as well as that of previously reported 7 and 8, was assessed on CT26 (mouse colon carcinoma), U87 (human glioblastoma), MCF-7 (human breast adenocarcinoma), and RPE-1 (human normal retina pigmented epithelium) cell lines. In general, the IC50 values correlate with the hydrophobicity of the compounds (measured as octanol-H2O partition coefficients) and do not show an appreciable level of selectivity against cancer cells with respect to the nontumor ones.

Formula: C24H34O2On October 25, 2021 ,《Density Functional Theory-Inspired Design of Ir/P,S-Catalysts for Asymmetric Hydrogenation of Olefins》 was published in Organometallics. The article was written by Faiges, Jorge; Borras, Carlota; Pastor, Isidro M.; Pamies, Oscar; Besora, Maria; Dieguez, Montserrat. The article contains the following contents:

In silico-based optimization of Ir/P,S-catalysts for the asym. hydrogenation of unfunctionalized olefins using (E)-1-(but-2-en-2-yl)-4-methoxybenzene as a benchmark olefin has been carried out. DFT calculations revealed that the thioether group has a major role in directing the olefin coordination. This, together with the configuration of the biphenyl phosphite group, has an impact in maximizing the energy gap between the most stable transition states leading to opposite enantiomers. As a result, the optimized catalyst proved to be efficient in the hydrogenation of a range of alkenes with the same substitution pattern and olefin geometry as the benchmark olefin, regardless of the presence of functional groups with different coordination abilities (ee values up to 97%). Appealingly, further modifications at the thioether groups and at the biaryl phosphite moiety allowed the highly enantioselective hydrogenation of olefins with different substitution patterns (e.g., α,β-unsaturated lactones and lactams, 1,1′-disubstituted enol phosphinates, and cyclic β-enamides; ee values up to >99%).(R)-3,3′-Di-tert-butyl-5,5′,6,6′-tetramethylbiphenyl-2,2′-diol(cas: 329735-68-4Formula: C24H34O2) was used in this study.

(R)-3,3′-Di-tert-butyl-5,5′,6,6′-tetramethylbiphenyl-2,2′-diol(cas: 329735-68-4) belongs to phenols. Phenols are more acidic than typical alcohols. The acidity of the hydroxyl group in phenols is commonly intermediate between that of aliphatic alcohols and carboxylic acids (their pKa is usually between 10 and 12).Formula: C24H34O2

Synthetic Route of C6H12O6On October 31, 2019 ,《Initial pyrolysis mechanism of cellulose revealed by in-situ DRIFT analysis and theoretical calculation》 appeared in Combustion and Flame. The author of the article were Dai, Gongxin; Wang, Kaige; Wang, Guanyu; Wang, Shurong. The article conveys some information:

Cellulose is one of the major components of biomass. The study on its pyrolysis process will be beneficial to the in-depth understanding of biomass pyrolysis mechanism. In this work, in-situ diffuse reflectance IR Fourier transform spectroscopy (in-situ DRIFT) combined with two-dimensional perturbation correlation IR spectroscopy (2D-PCIS) was first used to characterize the evolution process of the functional groups in cellulose during pyrolysis.

Formula: C6H12O6On September 15, 2021 ,《Chemical structure and anti-inflammatory activity of a branched polysaccharide isolated from Phellinus baumii》 was published in Carbohydrate Polymers. The article was written by Sun, Yuqing; Huo, Jinxi; Zhong, Shi; Zhu, Jianxun; Li, Yougui; Li, Xiaojun. The article contains the following contents:

Phellinus baumii is used to treat inflammatory bowel disease (IBD) and gastroenteritis. In this study, a 46 kDa heteropolysaccharide SHPS-1 was isolated from fruiting bodies of P. baumii. SHPS-1 consisted of arabinose, mannose, glucose, and galactose at a molar ratio of 2.2:15.7:49.3:32.8. SHPS-1 had a backbone containing 1,3-linked β-D-Glcp and 1,6-linked α-D-Galp residues, and Araf, Manp and Galp units were attached as oligosaccharidic side chains to the backbone at C-6 of some glucopyranoses. SHPS-1 decreased phosphorylation level of STAT-1 and expression levels of STAT-1 targeted genes such as iNOS and TNF-α in lipopolysaccharide-stimulated macrophage RAW 264.7 cells. Furthermore, SHPS-1 promoted the expression of IL-10 and macrophage mannose receptor CD 206, markers of tissue repairing macrophages. SHPS-1 alleviated ulcerative colitis in mice by decreasing pro-inflammatory genes and increasing anti-inflammatory and tissue repairing genes. Collectively, SHPS-1 polysaccharide from P. baumii had anti-inflammatory activity and can potentially treat IBD. In the experiment, the researchers used rel-(3R,4S,5S,6R)-6-(Hydroxymethyl)tetrahydro-2H-pyran-2,3,4,5-tetraol(cas: 54-17-1Formula: C6H12O6)
