And the article contained the following:

Organic materials typically present low rate performance and limited cycling durability due to the structural destruction and dissolution during electrochem. processes, which greatly hinders their application as promising cathodes for aqueous rechargeable zinc-ion batteries (ZIBs). Here, a strategy of in situ electrochem. oxidation with π-π interaction coupling between graphene and 2,3,6,7,10,11-Hexahydroxytriphenylene (HHTP) stabilizes the composite structure, rendering it a very promising organic composite cathode (named as GH) for ZIBs. More explicitly, the hydroxyl groups of HHTP are in-situ electrochem. transformed into carbonyl groups to form the redox-active sites, in which π-π interactions with graphene urges the highly reversible coordination/incoordination between zinc ions and the GH cathode. Further, such a GH cathode shows a specific capacity of 225 mAh g-1 at 0.05 A g-1 with a high capacity retention of 90% at 10 A g-1 after 7000 cycles, demonstrating high rate and cycle stability are achieved during the discharge/charge process. Thereby, this work provides a novel strategy for engineering an organic composite cathode which corrects the low rate and unstable cycling property for effective use in ZIBs. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).Electric Literature of 91-16-7

On January 10, 2022, Starace, Anne K.; Lee, David D.; Hietala, Kristen T.; Kim, Yeonjoon; Kim, Seonah; Harman-Ware, Anne E.; Carpenter, Daniel L. published an article.HPLC of Formula: 91-16-7 The title of the article was Predicting Catalytic Pyrolysis Aromatic Selectivity from Pyrolysis Vapor Composition Using Mass Spectra Coupled with Statistical Analysis. And the article contained the following:

The behavior of fast pyrolysis (FP) and catalytic FP (CFP) of 20 renewable feedstocks was studied in a microscale reactor with mol. beam mass spectral anal. of products generated. A partial least-squares (PLS) model was constructed based on the FP vapor spectra that predicts the aromatic selectivity when upgrading over a ZSM-5 catalyst. Addnl., principal component anal. of both FP and CFP spectra was performed for comprehensive spectral anal. This work highlighted the value of vapor-phase mass spectral screening to predict the subsequent feedstock performance and demonstrated that the quantity of coke deposited on the catalyst is not a reliable measure of catalyst deactivation when the feedstock type is varied. The experimental process involved the reaction of 1,2-Dimethoxybenzene(cas: 91-16-7).HPLC of Formula: 91-16-7

Hullar, Ted; Tran, Theo; Chen, Zekun; Bononi, Fernanda; Palmer, Oliver; Donadio, Davide; Anastasio, Cort published an article in 2022, the title of the article was Enhanced photodegradation of dimethoxybenzene isomers in/on ice compared to in aqueous solution.HPLC of Formula: 91-16-7 And the article contains the following content:

Photochem. reactions of contaminants in snow and ice can be important sinks for organic and inorganic compounds deposited onto snow from the atm. and sources for photoproducts released from snowpacks into the atm. Snow contaminants can be found in the bulk ice matrix, in internal liquid-like regions (LLRs), or in quasi-liquid layers (QLLs) at the air-ice interface, where they can readily exchange with the firn air. Some studies have reported that direct photochem. reactions occur faster in LLRs and QLLs than in aqueous solution, while others have found similar rates. Here, we measure the photodegradation rate constants for loss of the three dimethoxybenzene isomers under varying exptl. conditions, including in aqueous solution, in LLRs, and at the air-ice interface of nature-identical snow. Relative to aqueous solution, we find modest photodegradation enhancements (3- and 6-fold) in LLRs for two of the isomers and larger enhancements (15- to 30-fold) at the air-ice interface for all three isomers. We use computational modeling to assess the impact of light absorbance changes on photodegradation rate enhancements at the interface. We find small (2-5 nm) bathochromic (red) absorbance shifts at the interface relative to in solution, which increases light absorption, but this factor only accounts for less than 50% of the measured rate constant enhancements. The major factor responsible for photodegradation rate enhancements at the air-ice interface appears to be more efficient photodecay: estimated dimethoxybenzene quantum yields are 6- to 24-fold larger at the interface compared to in aqueous solution and account for the majority (51%-96%) of the observed enhancements. Using a hypothetical model compound with an assumed Gaussian-shaped absorbance peak, we find that a shift in the peak to higher or lower wavelengths can have a minor to substantial impact on photodecay rate constants, depending on the original location of the peak and the magnitude of the shift. Changes in other peak properties at the air-ice interface, such as peak width and height (i.e., molar absorption coefficient), can also impact rates of light absorption and direct photodecay. Our results suggest our current understanding of photodegradation processes underestimates the rate at which some compounds are broken down, as well as the release of photoproducts into the atm.

On September 18, 2020, Grimm, Christopher; Lazzarotto, Mattia; Pompei, Simona; Schichler, Johanna; Richter, Nina; Farnberger, Judith E.; Fuchs, Michael; Kroutil, Wolfgang published an article.Safety of 1,2-Dimethoxybenzene The title of the article was Oxygen-free regioselective biocatalytic demethylation of methyl-ph ethers via methyltransfer employing veratrol-O-demethylase. And the article contained the following:

The cleavage of aryl Me ethers is a common reaction in chem. requiring rather harsh conditions; consequently, it is prone to undesired reactions and lacks regioselectivity. Nevertheless, O-demethylation of aryl Me ethers is a tool to valorize natural and pharmaceutical compounds by deprotecting reactive hydroxyl moieties. Various oxidative enzymes are known to catalyze this reaction at the expense of mol. oxygen, which may lead in the case of phenols/catechols to undesired side reactions (e.g., oxidation, polymerization). Here an oxygen-independent demethylation via Me transfer is presented employing a cobalamin-dependent veratrol-O-demethylase (vdmB). The biocatalytic demethylation transforms a variety of aryl Me ethers with two functional methoxy moieties either in 1,2-position or in 1,3-position. Biocatalytic reactions enabled, for instance, the regioselective monodemethylation of substituted 3,4-dimethoxy phenol as well as the monodemethylation of 1,3,5-trimethoxybenzene. The methyltransferase vdmB was also successfully applied for the regioselective demethylation of natural compounds such as papaverine and rac-yatein. The approach presented here represents an alternative to chem. and enzymic demethylation concepts and allows performing regioselective demethylation in the absence of oxygen under mild conditions, representing a valuable extension of the synthetic repertoire to modify pharmaceuticals and diversify natural products.

Drogkaris, Vasileios; Northrop, Brian H. published an article in 2020, the title of the article was Discrete boronate ester ladders from the dynamic covalent self-assembly of oligo(phenylene ethynylene) derivatives and phenylenebis(boronic acid).Safety of 1,2-Dimethoxybenzene And the article contains the following content:

Three increasingly π-conjugated covalent organic polygons have been prepared by the dynamic covalent condensation of catechol-based oligo(phenylene ethynylene) derivatives with phenylenebis(boronic acid). The assemblies represent a series of boronate ester “ladders” wherein two electron rich oligo(phenylene ethynylene) “rungs” are bridged by electron deficient aryl boronate ester “rails”, resulting in quasi-two-dimensional oligomers of increasing size. Spectroscopic and computational investigations suggest that the ladders exhibit a greater effective conjugation length than comparable oligo(phenylene ethynylene) compounds not bridged by aryl boronate esters. Different conformations, substitutions, and constitutions of boronate ester ladders are also modeled to gain further insight into their influence on π-conjugation and HOMO-LUMO gaps of isolated one-dimensional vs. bridged, quasi-two-dimensional conjugated organic materials.

Two naphthalene-containing compounds, 4-hydroxy-6,7-dimethoxy-1-(4-(trifluoromethyl)phenyl)-2-naphthoic acid (A) and 4-hydroxy-6,7-dimethoxy-1-phenyl-2-naphthoic acid (B), were prepared by several steps. Their bindings to human serum albumin (HSA) were studied by UV-visible (UV-vis) absorption, fluorescence, synchronous fluorescence, three-dimensional fluorescence, CD (CD) spectroscopies and mol. docking. The crystal data of these compounds show the structure of the compounds The results show that the mechanism of the interaction between compound A and HSA is mixed-quenching (both dynamic and static quenching), while that of compound B and HSA is static quenching. The number of binding sites, binding constants and binding distance (r) were obtained. The interaction processes are spontaneous. A mainly interacts with HSA through typical hydrophobic interaction, and B binds to HSA mainly by the hydrogen bonds and van der Waals forces. The conformation of HSA changes slightly after the addition of the compounds Besides, mol. docking method was used to study the interaction details between the compounds and HSA. This is helpful to understand the absorption and metabolism of these two compounds in the body, and provides a basis for designing naphthalene-containing drugs. Communicated by Ramaswamy H.

And the article contained the following:

The interaction between food crops and insect pests is mediated by semiochems. emitted from host plants. These semiochems. are natural behavioral modifiers and act on the insect olfactory system to locate hosts and preys. In this study, eight rice neuroactive semiochems. were identified from rice varieties by GC-EAG and GC-MS. Their ability to modify rice pest behaviors was further studied as individual chems. and physiol. relevant blend. The total amount of each semiochem. and the expression of their biosynthesis genes were significantly higher in pest susceptible variety than in pest-resistant variety and upregulated by the infestation of the pest Nilaparvata lugens (BPH). The semiochems. emitted by uninfested plants (UIRVs) were more attractive to BPHs. Interestingly, the attractiveness of UIRVs was significantly reduced by the addition of the blend that mimics the natural composition of these semiochems. emitted by infested plants (IRVs). Our study suggests a mechanism for the spread of pest infestation from infested plants to uninfested plants nearby. UIRVs initially serve as attractive signals to rice insect pests. The pest infestation changes the rice semiochem. profile to be less attractive or even repellent, which pushes further colonization to uninfested plants nearby. The identified semiochems. can be used for crop protection based on a push-pull strategy.
