On November 1, 2021, Sun, Haoran; Luo, Zhongyang; Wang, Wenbo; Li, Simin; Xue, Shuang published an article.Product Details of 91-16-7 The title of the article was Porosity roles of micro-mesostructured ZSM-5 in catalytic fast pyrolysis of cellulolytic enzyme lignin for aromatics. And the article contained the following:

Cellulolytic enzyme lignin could be utilized to produce aromatic-rich bio-oil in the catalytic fast pyrolysis (CFP) process, in which strong-acidic ZSM-5 is often used as the catalyst. The introduction of mesopores into conventional ZSM-5 catalysts can improve the diffusion of heavy components and thus enable the modulation of pyrolysis products. To investigate the effect of mesoporous structure parameters on the diffusion of heavy phenols and the regulation of pyrolysis products by different types of pore structures, three different mesoporous ZSM-5 were prepared (core-shell, hierarchical, composites), with textural properties being compared in detail. The structural parameters were adopted to analyze the relationship between mesopores distribution and catalytic performance, revealing the significant effect of equivalent mesopore size. Among the prepared catalysts, a micro-mesostructured composite zeolite (ZMA) with internal hierarchical pores and ununiform mesolayer shell had a suitable mesostructure, of which the interconnected meso-channels improved the accessibility of inner acidic sites. Also, it was optimum to balance aromatic yield (above 7.5 wt%) and the product distribution (MAHs/PAHs approaching 6), revealing that its moderate equivalent pore size maintained a certain shape-selectivity to suppress PAHs formation. It was further shown that the applicable catalyst to lignin ratio (C/L) ranges differed with various mesostructures, as ZMA and hierarchical samples were suitable for higher and lower ratios, resp. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Product Details of 91-16-7

On December 25, 2020, Tran, Quoc Khanh; Han, Sangjin; Ly, Hoang Vu; Kim, Seung-Soo; Kim, Jinsoo published an article.Recommanded Product: 91-16-7 The title of the article was Hydrodeoxygenation of a bio-oil model compound derived from woody biomass using spray-pyrolysis-derived spherical γ-Al2O3-SiO2 catalysts. And the article contained the following:

In this study, spherical γ-Al2O3-SiO2 catalysts with various Al/Si ratios were prepared by combining the sol-gel and spray pyrolysis (SP) methods. The effectiveness of the product catalysts was then tested via the hydrodeoxygenation (HDO) of guaiacol, a model compound of bio-oil obtained from the pyrolysis of lignocellulosic biomass. Our results showed that the γ-Al2O3-SiO2 catalyst with a 50:50 Al/Si ratio after calcination at 450°C exhibited the highest guaiacol conversion (81.79%) at a reaction temperature of 300°C, atm. pressure, and a weight hourly space velocity (WHSV) of 6.5 h-1. During guaiacol HDO, the carbon-oxygen cleavage and Me group transfer reactions occurred on the γ-Al2O3-SiO2 catalyst, which converted the guaiacol into the resp. deoxygenated products, including 2,6-xylenol, 2,3,5,6-tetra-Me phenol, pentamethyl benzene, and hexamethyl benzene. The reaction pathways for the conversion of guaiacol HDO were also proposed in this study. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Recommanded Product: 91-16-7

And the article contained the following:

Aromatic organosilanes bearing C(sp2)-Si bonds found increasing applications across the chem. science, yet are mostly produced by atom-uneconomical stoichiometric procedures. Catalytic alternatives using hydrosilanes as Si sources also were described, but they display unfavorable thermodn. and are mostly based on expensive catalytic systems, often derived from noble metals, or lack generality. Herein, the authors describe the use of an alternative Si source, the tert-butyl-substituted silyldiazenes (tBu-N:N-SiR3), that are readily accessible from com. available precursors and whose structure enables the C(sp2)-H bond silylation of unactivated heteroaryl and aryl compounds under ambient, transition-metal-free catalytic conditions. The experimental process involved the reaction of 1-Fluoro-2-methoxybenzene(cas: 321-28-8).Product Details of 321-28-8

And the article contained the following:

Targeting redox vulnerability of cancer cells by pro-oxidants capable of generating reactive oxygen species (ROS) has surfaced as an important anticancer strategy. Due to the intrinsic narrow therapeutic window and other dangerous side effects of ROS generation, it is highly needed and challenging to develop pro-oxidative anticancer agents (PAAs) with high selectivity for generating ROS in cancer cells. Herein we report a hydrogen peroxide (H2O2)-activated Cu(II) pro-ionophore strategy to develop naphthazarin (Nap) as such type of PAAs based on the H2O2-mediated conversion of boronate to free phenol. The boronate-protected Nap (PNap) can exploit increased levels of H2O2 in HepG2 cells to in situ release Nap followed by its efflux via conjugation with reduced glutathione (GSH), allowing that the Nap-GSH adduct works as a Cu(II) ionophore to induce continuously GSH depletion via a reduction-dependent releasing of Cu(I) by GSH. This strategy endows PNap with the unprecedented ability to hit multi-redox characteristics (increased levels of H2O2, GSH and copper) of HepG2 cells, leading to ROS generation preferentially in HepG2 cells along with their selective death.

And the article contained the following:

The formation of several silyl ethers (alkoxysilanes, R3Si-OR’) and unsym. siloxanes (R3Si-O-SiR’3) can be catalyzed by the com. available potassium bis(trimethylsilyl)amide (KHMDS). The reaction proceeds via direct dealkynative coupling between various alcs. or silanols and alkynylsilanes, with a simultaneous formation of gaseous acetylene as the sole byproduct. The dehydrogenative and dealkenative coupling of alcs. or silanols are well-investigated, while the utilization of alkynylsilanes as silylating agents has never been comprehensively studied in this context. Overall, the presented system allows the synthesis of various attractive organosilicon compounds under mild conditions, making this approach an atom-efficient, environmentally benign, and sustainable alternative to existing synthetic solutions The experimental process involved the reaction of 2-(2-(Vinyloxy)ethoxy)ethanol(cas: 929-37-3).Reference of 2-(2-(Vinyloxy)ethoxy)ethanol

And the article contained the following:

Novel analogs of C-2-substituted thienopyrimidine-based bisphosphonates (C2-ThP-BPs) are described that are potent inhibitors of the human geranylgeranyl pyrophosphate synthase (hGGPPS). Members of this class of compounds induce target-selective apoptosis of multiple myeloma (MM) cells and exhibit antimyeloma activity in vivo. A key structural element of these inhibitors is a linker moiety that connects their (((2-phenylthieno[2,3-d]pyrimidin-4-yl)amino)methylene)bisphosphonic acid core to various side chains. The structural diversity of this linker moiety, as well as the side chains attached to it, was investigated and found to significantly impact the toxicity of these compounds in MM cells. The most potent inhibitor CML-07-119(13c)(I) was evaluated in mouse and rat for liver toxicity and systemic exposure, resp., providing further optimism for the potential value of such compounds as human therapeutics.

On July 29, 2020, Kang, Chengjun; Zhang, Zhaoqiang; Wee, Vanessa; Usadi, Adam K.; Calabro, David C.; Baugh, Lisa Saunders; Wang, Shun; Wang, Yuxiang; Zhao, Dan published an article.Electric Literature of 150-78-7 The title of the article was Interlayer Shifting in Two-Dimensional Covalent Organic Frameworks. And the article contained the following:

Layer-stacking structures are very common in two-dimensional covalent organic frameworks (2D COFs). While their structures are normally determined under solvent-free conditions, the structures of solvated 2D COFs are largely unexplored. We report herein the in situ determination of solvated 2D COF structures, which exhibit an obvious difference as compared to that of the same COF under dried state. Powder X-ray diffraction (PXRD) data analyses, computational modeling, and Pawley refinement indicate that the solvated 2D COFs experience considerable interlayer shifting, resulting in new structures similar to the staggered AB stacking, namely, quasi-AB-stacking structures, instead of the AA-stacking structures that are usually observed in the dried COFs. We attribute this interlayer shifting to the interactions between COFs and solvent mols., which may weaken the attraction strength between adjacent COF layers. D. functional theory (DFT) calculations confirm that the quasi-AB stacking is energetically preferred over the AA stacking in solvated COFs. All four highly crystalline 2D COFs examined in the present study exhibit considerable interlayer shifting upon solvation, implying the universality of the solvent-induced interlayer stacking rearrangement in 2D COFs. These findings prompt re-examination of the 2D COF structures in solvated state and suggest new opportunities for the applications of COF materials under wet conditions. The experimental process involved the reaction of 1,4-Dimethoxybenzene(cas: 150-78-7).Electric Literature of 150-78-7

BACKGROUNDTo extract natural volatile compounds from tea (Camellia sinensis) flowers without thermal degradation and residue of organic solvents, supercritical fluid extraction (SFE) using carbon dioxide was employed to prepare essential oil of tea flowers in the present study. Four important parameters-pressure, temperature, static extraction time, and dynamic extraction time-were selected as independent variables in the SFE. RESULTSThe optimum extraction conditions were the pressure of 30 MPa, temperature of 50°C, static time of 10 min, and dynamic time of 90 min. Based on gas chromatog.-mass spectrometry anal., 59 compounds, including alkanes (45.4%), esters (10.5%), ketones (7.1%), aldehydes (3.7%), terpenes (3.7%), acids (2.1%), alcs. (1.6%), ethers (1.3%) and others (10.3%) were identified in the essential oil of tea flowers. Moreover, the essential oil of tea flowers showed relatively stronger DPPH radical scavenging activity than essential oils of geranium and peppermint, although its antioxidative activity was weaker than those of essential oil of clove, ascorbic acid, tert-butylhydroquinone, and butylated hydroxyanisole. CONCLUSIONEssential oil of tea flowers using SFE contained many types of volatile compounds and showed considerable DPPH scavenging activity. The information will contribute to the future application of tea flowers as raw materials in health-care food and food flavor industries. © 2013 Society of Chem. Industry.

On December 31, 2003, Wang, Y.; Somers, E. B.; Manolache, S.; Denes, F. S.; Wong, A. C. L. published an article.Related Products of 929-37-3 The title of the article was Cold plasma synthesis of poly(ethylene glycol)-like layers on stainless-steel surfaces to reduce attachment and biofilm formation by Listeria monocytogenes. And the article contained the following:

Poly(ethylene glycol) (PEG)-like structures were generated on stainless steel under di(ethylene glycol) vinyl ether (DiEGVE) radio frequency-plasma environments. Electron spectroscopy for chem. anal. and attenuated total reflectance Fourier transform IR spectroscopy indicated a PEG-like deposition, which was stable to cleaning, sanitizing, and storage for up to 2 mo. At. force microscopy and water contact angle anal. indicated that the modified stainless-steel surfaces were less rough and more hydrophilic than the unmodified surfaces. Listeria monocytogenes attachment and biofilm formation on modified surfaces decreased more than 90% compared with the unmodified stainless steel (P < 0.01). DiEGVE cold plasma was demonstrated to be a promising technique to reduce bacterial contamination on surfaces encountered in food-processing environments.
