Stable Dendrite-Free Sodium-Sulfur Batteries Enabled by a Localized High-Concentration Electrolyte was written by He, Jiarui;Bhargav, Amruth;Shin, Woochul;Manthiram, Arumugam. And the article was included in Journal of the American Chemical Society in 2021.Category: ethers-buliding-blocks This article mentions the following:

Ambient-temperature sodium-sulfur batteries are an appealing, sustainable, and low-cost alternative to lithium-ion batteries due to their high material abundance and specific energy of 1274 W h kg^-1. However, their viability is hampered by Na polysulfide (NaPS) shuttling, Na loss due to side reactions with the electrolyte, and dendrite formation. Here, we demonstrate that a solid-electrolyte interphase rich in inorganic components can be realized at both the sulfur cathode and the Na anode by tweaking the solvation structure of the electrolyte. This transforms the sulfur redox process from conventional dissolution-precipitation chem. into a quasi-solid-state reaction, which eliminates NaPS shuttling and facilitates dendrite-free Na-metal plating and stripping. With the solvated ionic liquid electrolyte structure, a high initial capacity of 922 mA h g^-1 with a capacity fade of as low as 0.10% per cycle over 300 cycles was achieved. The scalability of this approach to pouch cells with practically necessary parameters demonstrates its potential for practical viability. In the experiment, the researchers used many compounds, for example, 2,5,8,11-Tetraoxadodecane (cas: 112-49-2Category: ethers-buliding-blocks).

2,5,8,11-Tetraoxadodecane (cas: 112-49-2) belongs to ethers. Ether is less polar than esters, alcohols or amines because of the oxygen atom that is unable to participate in hydrogen bonding due to the presence of bulky alkyl groups on both sides of the oxygen atom. Ethers can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds. The ability to form hydrogen bonds with other compounds makes ethers particularly good solvents for a wide variety of organic compounds and a surprisingly large number of inorganic compounds.Category: ethers-buliding-blocks

And the article was included in Polymer in 2021.Application of 111-77-3 This article mentions the following:

Influence of polyethylene glycol unit on nickel catalyzed ethylene polymerization have attracted increasing interest. The Lewis basic oxygen atoms on polyethylene glycol group can form interactions with Lewis acidic metal additives. In this contribution, a series of iminopyridyl ligands (L-O1, L-O2 and L-O3) bearing polyethylene glycol units and corresponding nickel complexes (Ni-O1, Ni-O2 and Ni-O3) were designed, synthesized and characterized. By the activation of alkylaluminium cocatalysts, the nickel complexes and their corresponding MgCl₂-supported nickel precatalysts (Ni-O1-Mg, Ni-O2-Mg and Ni-O3-Mg) were investigated in catalytic homogeneous and heterogeneous ethylene polymerization, resp. The mol. weight of products increased with the number of oxygen atoms on polyethylene glycol unit increasing. The introduction of the MgCl₂ support resulted in much higher mol. weights and much lower branched densities of polyethylenes than those of products generated in the homogeneous polymerizations The polymers generated in heterogeneous polymerizations have excellent polymer powder morphol. to prevent reactor fouling, facilitating potential industrial applications. In the experiment, the researchers used many compounds, for example, 2-(2-Methoxyethoxy)ethanol (cas: 111-77-3Application of 111-77-3).

2-(2-Methoxyethoxy)ethanol (cas: 111-77-3) belongs to ethers. Of all the functional groups, ethers are the least reactive ones. Ether bonds are quite stable towards bases, oxidizing agents and reducing agents. Ethers can form hydrogen bonds with other molecules (alcohols, amines, etc.) that have O―H or N―H bonds.

Luminescent Vesicles Self-assembled Directly from an Amphiphilic Europium Complex in an Ionic Liquid was written by Li, Qingrun;Song, Shenghan;Feng, Zhenyu;Qiu, Juan;Sun, Meng;Chen, Xiao. And the article was included in Langmuir in 2020.Related Products of 111-77-3 This article mentions the following:

Novel luminescent vesicles with enhanced emission were achieved by an amphiphilic Eu complex through its spontaneously self-assembly in an ionic liquid, 1-butyl-3-methylimidazolium hexafluorophosphate ([Bmim]PF₆). The complex was prepared by Eu ions coordinated with terpyridine ligands, which were modified with the hydrophilic ethoxy chains. The enhanced absolute quantum yield and prolonged fluorescence lifetime of complex in vesicles were observed because of the effective shielding of the quench effects caused by both solvent and complex concentration Compared to the aggregates formed in other solvents, the vesicles obtained in [Bmim]PF₆ showed the best luminescence intensity with the quantum efficiency (37.74%) and luminescent emission lifetime (1.915 ms) both increased ∼10 times more. This Eu complex was designed to show unsaturated coordination, which made the vesicle luminescence easily quenched when contacting with H₂O. The fluorescence sensing of H₂O with this vesicle as probe was possible, where several unique properties like high sensitivity, low detection limit (0.05 volume%), visible color change, and fast response had been observed Such designed systems are expected to provide strategies to develop novel supramol. aggregates in ionic liquids and offer guidance for luminescence detection with facile and wide applications. In the experiment, the researchers used many compounds, for example, 2-(2-Methoxyethoxy)ethanol (cas: 111-77-3Related Products of 111-77-3).

“Quinone Millipedes” Reconsidered: Evidence for a Mosaic-Like Taxonomic Distribution of Phenol-Based Secretions across the Julidae was written by Bodner, Michaela;Vagalinski, Boyan;Makarov, Slobodan E.;Antic, Dragan Z.;Vujisic, Ljubodrag V.;Leis, Hans-Joerg;Raspotnig, Guenther. And the article was included in Journal of Chemical Ecology in 2016.Category: ethers-buliding-blocks This article mentions the following:

The defensive chem. of juliformian millipedes is characterized mainly by benzoquinones (“quinone millipedes”), whereas the secretions of the putative close outgroup Callipodida are considered to be exclusively phenolic. We conducted a chem. screening of julid secretions for phenolic content. Most species from tribes Cylindroiulini (15 species examined), Brachyiulini (5 species examined), Leptoiulini (15 species examined), Uncigerini (2 species examined), Pachyiulini (3 species examined), and Ommatoiulini (2 species examined) had non-phenolic, in most cases exclusively benzoquinonic secretions. In contrast, tribes Cylindroiulini, Brachyiulini, and Leptoiulini also contained representatives with predominantly phenol-based exudates. In detail, p-cresol was a major compound in the secretions of the cylindroiulines Styrioiulus pelidnus and S. styricus (p-cresol content 93 %) and an undetermined Cylindroiulus species (p-cresol content 51 %), in the brachyiulines Brachyiulus lusitanus (p-cresol content 21 %) and Megaphyllum fagorum (p-cresol content 92 %), as well as in an undescribed Typhloiulus species (p-cresol content 32 %, Leptoiulini). In all species, p-cresol was accompanied by small amounts of phenol. The secretion of M. fagorum was exclusively phenolic, whereas phenols were accompanied by benzoquinones in all other species. This is the first incidence of clearly phenol-dominated secretions in the Julidae. We hypothesize a shared biosynthetic route to phenols and benzoquinones, with benzoquinones being produced from phenolic precursors. The patchy taxonomic distribution of phenols documented herein supports multiple independent regression events in a common pathway of benzoquinone synthesis rather than multiple independent incidences of phenol biosynthesis. In the experiment, the researchers used many compounds, for example, 2,3-Dimethoxy-5-methylcyclohexa-2,5-diene-1,4-dione (cas: 605-94-7Category: ethers-buliding-blocks).

2,3-Dimethoxy-5-methylcyclohexa-2,5-diene-1,4-dione (cas: 605-94-7) belongs to ethers. Of all the functional groups, ethers are the least reactive ones. Ether bonds are quite stable towards bases, oxidizing agents and reducing agents. Electron-deficient reagents are also stabilized by ethers. For example, borane (BH3) is a useful reagent for making alcohols. Pure borane exists as its dimer, diborane (B2H6), a toxic gas that is inconvenient and hazardous to use. Borane forms stable complexes with ethers, however, and it is often supplied and used as its liquid complex with tetrahydrofuran (THF).Category: ethers-buliding-blocks

A process using only water as solvent is described for the synthesis of aryloxyacetic acids ArOCH₂CO₂H (Ar = Ph, 4-MeOC₆H₄, 4-ClC₆H₄, 1-naphthyl, 2-naphthyl, 3,5-Cl₂C₆H₃, 2,4-ClC₆H₃) under microwave irradiation In the experiment, the researchers used many compounds, for example, 2-(4-Methoxyphenoxy)acetic acid (cas: 1877-75-4Reference of 1877-75-4).

2-(4-Methoxyphenoxy)acetic acid (cas: 1877-75-4) belongs to ethers. Relative to alcohols, ethers are generally less dense, are less soluble in water, and have lower boiling points. They are relatively unreactive, and as a result they are useful as solvents for fats, oils, waxes, perfumes, resins, dyes, gums, and hydrocarbons. Vapours of certain ethers are used as insecticides, miticides, and fumigants for soil. Ethers are good solvents partly because they are not very reactive. Most ethers can be cleaved, however, by hydrobromic acid (HBr) to give alkyl bromides or by hydroiodic acid (HI) to give alkyl iodides.Reference of 1877-75-4

Dynamic nuclear polarization-magnetic resonance imaging at low ESR irradiation frequency for ascorbyl free radicals was written by Ito, Shinji;Hyodo, Fuminori. And the article was included in Scientific Reports in 2016.Product Details of 605-94-7 This article mentions the following:

Highly water-soluble ubiquinone-0 (CoQ₀) reacts with ascorbate monoanion (Asc) to mediate the production of ascorbyl free radicals (AFR). Using aqueous reaction mixture of CoQ₀and Asc, we obtained pos. enhanced dynamic nuclear polarization (DNP)-magnetic resonance (MR) images of the AFR at low frequency (ranging from 515 to 530 MHz) of ESR (ESR) irradiation The shape of the determined DNP spectrum was similar to ESR absorption spectra with doublet spectral peaks. The relative locational relationship of spectral peaks in the DNP spectra between the AFR (520 and 525 MHz), 14N-labeled carbamoyl-PROXYL (14N-CmP) (526.5 MHz), and Oxo63 (522 MHz) was different from that in the X-band ESR spectra, but were similar to that in the 300-MHz ESR spectra. The ratio of DNP enhancement to radical concentration for the AFR was higher than those for ¹⁴N-CmP, Oxo63, and flavin semiquinone radicals. The spectroscopic DNP properties observed for the AFR were essentially the same as those for AFR mediated by pyrroloquinoline quinone. Moreover, we made a success of in vivo DNP-MR imaging of the CoQ₀-mediated AFR which was administered by the s.c. and oral injections as an imaging probe. In the experiment, the researchers used many compounds, for example, 2,3-Dimethoxy-5-methylcyclohexa-2,5-diene-1,4-dione (cas: 605-94-7Product Details of 605-94-7).

2,3-Dimethoxy-5-methylcyclohexa-2,5-diene-1,4-dione (cas: 605-94-7) belongs to ethers. Ether is less polar than esters, alcohols or amines because of the oxygen atom that is unable to participate in hydrogen bonding due to the presence of bulky alkyl groups on both sides of the oxygen atom. But ether is more polar than alkenes. Autoxidation is the spontaneous oxidation of a compound in air. In the presence of oxygen, ethers slowly autoxidize to form hydroperoxides and dialkyl peroxides. If concentrated or heated, these peroxides may explode. To prevent such explosions, ethers should be obtained in small quantities, kept in tightly sealed containers, and used promptly.Product Details of 605-94-7

Switchable ROS Species Regulation Facilitates the Selective Oxidation of Benzyl Alcohols Enabled by an Organic Photocatalyst was written by Jia, Meng-Ze;Cui, Jing-Wang;Rao, Cai-Hui;Chen, Yun-Rui;Yao, Xin-Rong;Zhang, Jie. And the article was included in ACS Sustainable Chemistry & Engineering in 2022.Computed Properties of C8H10O2 This article mentions the following:

Benefiting from the regulation of ROS species through a simple and feasible strategy, an efficient and switchable photocatalytic protocol for the chemoselective synthesis of aldehydes and carboxylic acids via oxidation of primary alcs. under mild conditions was developed. Using the pyridinium derivative as a metal-free organic photocatalyst, a variety of benzyl alcs. can be converted into aldehydes or carboxylic acids under an air atm. at room temperature with high selectivity and yield via simple solvent regulation. A feasible tandem reaction combining the pyridinium-catalyzed alc.-to-aldehyde conversion and catalyst-free photoinduced oxidation of aromatic aldehydes provides a powerful and efficient approach for the one-pot oxidation of benzyl alcs. to carboxylic acids, while a small amount of water can effectively regulate the competition of electron transfer and energy transfer and inhibit the generation of carboxylic acids, facilitating highly efficient and selective oxidation of alcs. to aldehydes. In the experiment, the researchers used many compounds, for example, (4-Methoxyphenyl)methanol (cas: 105-13-5Computed Properties of C8H10O2).

(4-Methoxyphenyl)methanol (cas: 105-13-5) belongs to ethers. Ether is less polar than esters, alcohols or amines because of the oxygen atom that is unable to participate in hydrogen bonding due to the presence of bulky alkyl groups on both sides of the oxygen atom. But ether is more polar than alkenes. The unique properties of ethers (i.e., that they are strongly polar, with nonbonding electron pairs but no hydroxyl group) enhance the formation and use of many reagents. For example, Grignard reagents cannot form unless an ether is present to share its lone pair of electrons with the magnesium atom. Complexation of the magnesium atom stabilizes the Grignard reagent and helps to keep it in solution.Computed Properties of C8H10O2

And the article was included in Journal of Fish Diseases in 2021.Category: ethers-buliding-blocks This article mentions the following:

This study investigated the effects of Greek juniper extract on immune responses of rainbow trout. In this experiment, 4 doses [0 (Control), 1 (J1), 4 (J4) and 8 (J8) mg/kg] of the extract were administered orally using an oral gavage twice a day for 14 days. Immune responses were measured on 7th and 14th days. On 14th day, Yersinia ruckeri was injected i.p. to all fish of all groups. On 14th day, ORP in fish of J1 group increased significantly. Lysozyme activity (LA) was increased in J8 group on 7th day (p < .05). On 14th day, a significant decrease was determined in J1 and J4 treatments in LA. Myeloperoxidase activity was significantly decreased in all groups irresp. of sampling times (p < .05). Interleukin (IL)-1β was significantly elevated in fish of J8 group on 7th day. IL-8 increased in fish of J8 and J4 groups on 7th day of the study. IL-12 gene expression was significantly up-regulated in J8 fish group on 7th day, and in J4 fish group on 14th day. Survival rate was higher in J8 treatment compared to the control and other treatments (p < .05). The results suggest that Juniperus excelsa provides protection against Y. ruckeri in rainbow trout.

And the article was included in Bioorganic & Medicinal Chemistry Letters in 2019.Category: ethers-buliding-blocks This article mentions the following:

Quinuclidinyl N-phenylcarbamates and azabicyclic (arylethyl)phenylcarbamates such as I [R = 4-FC₆H₄, 4-MeOC₆H₄, 3,4-(MeO)₂C₆H₃] were prepared as ligands for the human M₅ muscarinic acetylcholine receptor (mAChR) for potential use in the treatment of drug abuse and chronic obstructive pulmonary disease; their binding to M₁-M₅ mAChR were determined I (R = 4-FC₆H₄) exhibited the highest affinities for M₁-M₅ mAChR (K_i = 2.0, 13, 2.6, 2.2, 1.8 nM for M₁, M₂, M₃, M₄, M₅ mAChR, resp.) of the tested ligands but was not selective for a single mAChR subtype. I (R = 4-FC₆H₄) acted as an agonist at mAChRs; the effect of I (R = 4-FC₆H₄) was inhibited by the nonselective mAChR antagonist scopolamine, and I (R = 4-FC₆H₄) augmented the release of dopamine evoked by oxotremorine. I (R = 4-MeOC₆H₄) was 17-fold selective for M₃ mAChR over M₂ mAChR.
