Successful Treatment of Vitiligo with Cold Atmospheric Plasma-Activated Hydrogel was written by Zhai, Siyue;Xu, Meifeng;Li, Qiaosong;Guo, Kun;Chen, Hailan;Kong, Michael G.;Xia, Yumin. And the article was included in Journal of Investigative Dermatology in 2021.COA of Formula: C13H12O2 The following contents are mentioned in the article:

Vitiligo shows insufficient response to current therapies largely owing to T-lymphocyte dysfunction, abnormal inflammatory activation, and excessive oxidative stress in lesions. Cold atm. plasma (CAP) possesses pleiotropic antioxidant and anti-inflammatory properties and may offer an improvement to current treatment options. In this study, the efficacy and safety of CAP were investigated in a mouse model of vitiligo and a randomized and controlled trial of patients with active focal vitiligo. Skin biopsies showed that topical treatment of vitiligo-like lesions on mouse dorsal skin by CAP restored the distribution of melanin. In addition, CAP treatment reduced the infiltration of CD11c⁺ dendritic cells, CD3⁺ T cells, and CD8⁺ T cells; inhibited the release of CXCL10 and cytokine IFN-γ; and enhanced cellular resistance to oxidative stress and excessive immune response by enhancing the expression of the transcription factor NRF2 and attenuating the activity of inducible nitric oxide synthase. In a randomized and controlled trial, CAP treatment achieved partial and complete repigmentation in 80% and 20% of vitiligo lesions, resp., without hyperpigmentation in surrounding areas or other adverse events during the treatment period and its follow-up period. In conclusion, CAP offers a promising option for the management of vitiligo. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2COA of Formula: C13H12O2).

4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.COA of Formula: C13H12O2

Remarkably Efficient Iridium Catalysts for Directed C(sp²)-H and C(sp³)-H Borylation of Diverse Classes of Substrates was written by Hoque, Emdadul Md;Hassan, Mirja Mahamudul Md;Chattopadhyay, Buddhadeb. And the article was included in Journal of the American Chemical Society in 2021.Recommanded Product: 1132669-90-9 The following contents are mentioned in the article:

Here we describe the discovery of a new class of C-H borylation catalysts and their use for regioselective C-H borylation of aromatic, heteroaromatic, and aliphatic systems. The new catalysts have Ir-C(thienyl) or Ir-C(furyl) anionic ligands instead of the diamine-type neutral chelating ligands used in the standard C-H borylation conditions. It is reported that the employment of these newly discovered catalysts show excellent reactivity and ortho-selectivity for diverse classes of aromatic substrates with high isolated yields. Moreover, the catalysts proved to be efficient for a wide number of aliphatic substrates for selective C(sp³)-H bond borylations. Heterocyclic mols. are selectively borylated using the inherently elevated reactivity of the C-H bonds. A number of late-stage C-H functionalization have been described using the same catalysts. Furthermore, we show that one of the catalysts could be used even in open air for the C(sp²)-H and C(sp³)-H borylations enabling the method more general. Preliminary mechanistic studies suggest that the active catalytic intermediate is the Ir(bis)boryl complex, and the attached ligand acts as bidentate ligand. Collectively, this study underlines the discovery of new class of C-H borylation catalysts that should find wide application in the context of C-H functionalization chem. This study involved multiple reactions and reactants, such as 5-Methoxy-2-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzaldehyde (cas: 1132669-90-9Recommanded Product: 1132669-90-9).

Selective organic phase hydrodeoxygenation of typical phenolic monomers and two lignin oils over highly active Pd/Hβ catalyst for high-grade bio-fuel production was written by Hu, Lin;Wei, Xian-Yong;Xu, Mei-Ling;Kang, Yu-Hong;Guo, Xian-Hou;Zhang, Feng-Bin;Zong, Zhi-Min;Bai, Hong-Cun. And the article was included in Journal of Environmental Chemical Engineering in 2021.Product Details of 103-16-2 The following contents are mentioned in the article:

The selective hydrodeoxygenation (HDO) of lignin-derived bio-oil still meets the great challenges due to its complex oxygenated organic component. In this research, first time, Pd-based zeolite catalysts were prepared by the modified deposition-precipitation (DP) method for the HDO conversion of guaiacol. Notably, for the same Si/Al ratio of zeolite, Pd_2%/Hβ catalyst showed the higher catalytic activity on the HDO of guaiacol than that Pd_2%/M and Pd_2%/HZSM-5 catalyst, which mainly originated from the synergetic effect between metal nanoparticles size and acid sites of catalyst. As one of typical phenolic monomers, guaiacol can be converted into high yield of hydrocarbons under the condition of 220°C, 3 MPa H₂, and 4 h in n-hexane over Pd_2%/Hβ (DP) catalyst. This highly active catalyst exhibited the good recyclability in the HDO conversion of guaiacol. In addition, other typical phenolic monomers can be converted into high yield of hydrocarbons over this highly active catalyst. Considering this, after HDO upgrading, real lignin oil (RLO) can be converted into high yield of hydrocarbons with the carbon number (CN) in range of C7-C15. This work highlighted that the depolymerization monomers from lignin can be further upgraded by this high active catalyst through HDO to obtain jet hydrocarbons fuel. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Product Details of 103-16-2).

4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Product Details of 103-16-2

4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Esters contain a carbonyl center, which gives rise to 120° C–C–O and O–C–O angles. Unlike amides, esters are structurally flexible functional groups because rotation about the C–O–C bonds has a low barrier. Their flexibility and low polarity is manifested in their physical properties; they tend to be less rigid (lower melting point) and more volatile (lower boiling point) than the corresponding amides.

The utilization of lignin to produce high value-added chems. is conducive to alleviating the fossil energy crisis. Herein, Ni nanoparticles supported on iron/nitrogen co-doped carbon was prepared by co-pyrolysis and solvothermal reduction method for catalytic hydrogenolysis (CH) of dealkaline lignin and its model compounds The catalysts were prepared under different calcination temperature, N/C ratio and Ni loading, and the optimal catalyst was Ni_10%@Fe/NC_0.33-800 (calcination temperature: 800°C, N/C ratio: 0.33, Ni loading: 10%) based the on the CH of benzyl Ph ether (BPE). Ni_10%@Fe/NC_0.33-800 showed good catalytic performance on the selective cleavage of C-O bond of lignin and its model compounds The BPE conversion reached up to 97.7% over Ni_10%@Fe/NC_0.33-800 under mild conditions (230°C, 1 MPa H₂, and 0.5 h) with toluene and cyclohexanol as major products. Catalyst characterizations suggest that N content affects the formation of NiFe alloy and the synergistic effect between Ni and Fe plays an important role in CH of BPE. Moreover, Ni_10%@Fe/NC_0.33-800 could promote the cleavage of C-O bonds in dealkaline lignin through CH and hence enhance producing aromatics such as phenols, aromatic ethers, and aromatic esters, among which phenols are the main aromatics with guaiacols predominant.

Efficient Ni-based catalysts for the hydrotreatment of lignin dimer model compounds to cycloalkanes/cycloalkanols was written by Chen, Changzhou;Wu, Dichao;Liu, Peng;Xia, Haihong;Zhou, Minghao;Hou, Xinglong;Jiang, Jianchun. And the article was included in Reaction Chemistry & Engineering in 2021.Name: 4-Benzyloxyphenol The following contents are mentioned in the article:

The noble-metal catalytic cleavage of ether bonds in lignin to obtain aromatic chems. has achieved great success, and the development of a low-cost efficient catalyst is crucial. Herein, Ni_xLa_y/CNT was designed for the hydrogenolysis of benzyl Ph ether (BPE), di-Ph ether (DPE) and 2-phenethyl Ph ether (PPE) under a relatively mild condition. Owing to the synergistic effect of Ni with La, the Ni-La catalyst was especially active. Moreover, not only could the Ni-La catalyst fracture the C-O bond, but it could also transform aromatic rings to produce cycloalkanes. Physicochem. characterizations were carried out by means of XRD, TEM, H₂-TPR, NH₃-TPD, pyridine-IR and XPS analyses. Based on the optimal reaction condition (240°C, 4 h, 2.0 MPa H₂), various model compounds could also be effectively hydrotreated to produce corresponding products. A mechanistic study revealed that cyclohexanol and methylcyclohexane were major products for the transfer cleavage of BPE. Furthermore, it has been illustrated that aryl groups played a significant role in the hydrogenation of phenol from the competitive catalytic hydrogenation reaction of phenol. This study opened up the possibility of the valorization of lignin using a rare earth metal as the co-catalyst for the selective cleavage of lignin model compounds to value-added chems.

Synthetic polymers constitute one of the main carbon-containing wastes generated nowadays. In this study, combined hydrothermal liquefaction (co-HTL) is evaluated for 1:1 mixtures of Miscanthus giganteus and different synthetic polymers-including poly-acrylonitrile-butadiene-styrene (ABS), bisphenol-A-based epoxy resin, high-d. polyethylene (HDPE), low-d. polyethylene (LDPE), polyamide 6 (PA6), polyamide 6/6 (PA66), poly(ethylene terephthalate) (PET), polycarbonate (PC), polypropylene (PP), polystyrene (PS), and polyurethane foam (PUR)-using batch HTL at 350°C. Based on oil yields and composition, a comprehensive discussion of observed interactions is presented. The results show that even though polyolefins do not depolymerize under these conditions, the oil products depict that these materials interact with miscanthus biocrude changing its composition Bisphenol-A-based polymers as PC and epoxy resins both contribute to the formation of monomer-like structures in the biocrude. PET increases the presence of carboxyl groups, while polyamides and PUR increase significantly the oil yield, modifying the biocrude composition toward nitrogen-containing mols. PUR co-HTL was found to increase oil, carbon, and energy yields, leading to process improvement when compared to pure miscanthus processing. HTL of synthetic polymers and biomass can be an opportunity for sustainable recycling of chems. in a synergistic, multipurpose process.

4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.SDS of cas: 103-16-2
