COA of Formula: C9H17NOOn September 1, 2021 ,《Comparative indexes, fuel characterization and thermogravimetric- Fourier transform infrared spectrometer-mass spectrogram (TG-FTIR-MS) analysis of microalga Nannochloropsis Oceanica under oxidative and inert torrefaction》 was published in Energy (Oxford, United Kingdom). The article was written by Zhang, Congyu; Ho, Shih-Hsin; Chen, Wei-Hsin; Wang, Rupeng. The article contains the following contents:

The torrefaction performances of microalga Nannochloropsis Oceanica under oxidative and inert atmospheres are characterized and compared with each other based on several operating parameters. By conducting several comparative indexes, the results suggest that oxidative torrefaction is more capable of upgrading microalgae due to its relatively lower solid yield and energy input, as well as relatively higher enhancement factor and upgrading energy index. Compared to inert torrefaction, the indexes indicate that oxidative torrefaction at 250°C for 30 min has higher energy yield (1.02 times) and energy efficiency (2.2 times) but whereas lower energy input (0.4 times). With increasing torrefaction severity, the pyrolysis curve gradually becomes smooth and shift to a high-temperature zone. The peak temperatures of torrefied microalgae present an increasing trend, especially in the oxidative atm. After oxidative torrefaction, microalgal solid biofuel is upgraded as peat and lignite, from the viewpoint of elemental composition Furthermore, oxidative torrefaction is more suitable than inert torrefaction for producing bio-oil which mainly contains dianhydromannitol, neophytadiene, and palmitoleic acid. The TG-FTIR-MS results uncover the pyrolysis characteristics and reactivity of torrefied microalgae, and elucidate that oxidative torrefied microalgae is more reactive.

《Converting coffee silverskin to value-added products by a slow pyrolysis-based biorefinery process》 was written by del Pozo, Cristina; Rego, Filipe; Yang, Yang; Puy, Neus; Bartroli, Jordi; Fabregas, Esteve; Bridgwater, Anthony V.. Synthetic Route of C9H17NO And the article was included in Fuel Processing Technology on April 30 ,2021. The article conveys some information:

This work aims to transform coffee silverskin (CSS), the only waste from the coffee roasting process, that worldwide amounts to about 76 million kg/yr, into value-added products within an integrated slow pyrolysis process. The study, performed at 280°C, 400°C and 500°C, determined the potential applications of the resulting fractions. Biochar has been studied as an adsorbent of organic pollutants in water, using methylene blue (MB) and methyl orange (MO), which are resp. cationic and anionic aromatic dyes, as model compounds, and with 400°C biochar giving the highest removal values, at 98% with MB and 40% with MO. Moreover, CSS biochar could be used to obtain renewable energy from its combustion, with 22.6-24.2 MJ/kg calorific values. The liquid fraction could be a potential source of caffeine, among phenolics, with 400°C aqueous phase presenting the highest concentration of caffeine (14.3 g/L). Concerning the gas fraction, it could be used to obtain heat for biomass drying before pyrolysis. Hence, use of the pyrolysis products as described would allow zero-waste to be achieved in the coffee roasting industry, thus promoting the green and circular economy and production of green chems. and materials in a biorefinery context.

The article was titled 《Mechanism Insight into Efficient Peroxydisulfate activation by Novel Nano Zero-valent Iron Anchored yCo3O4 (nZVI/yCo3O4) Composites》.SDS of cas: 826-36-8 The article contains the following contents:

Novel nano zero-valent iron anchored bio-matrix supported Co3O4 (nZVI/yCo3O4) composites were fabricated for tetracycline (TC) efficient degradation by activating peroxydisulfate (PS). The systematical characterizations verified that the nZVI/yCo3O4 composites with magnetism have higher surface area than yCo3O4 and pure Co3O4, contributing to more accessible active sites. Various catalytic parameters (nZVI mass ratio, leached ions, initial pH, catalyst dosage, PS concentration and coexisting anions) were thoroughly investigated. In nZVI/yCo3O4/PS system, 97.6%, 93.4% and 77.3% TC were degraded within 15 min at pH 3.0, 6.0 and 9.0, resp. Based on four successive degradation runs, the excellent mineralization rate and reusability of nZVI/yCo3O4 composites were mainly benefited from the suppressed metals leaching. The PS activated mechanisms were proposed as non-radicals (1O2) dominated pattern at acidic conditions and radicals (SO•-4) predominant pattern at alk. environment, which may be highly related to the electron donating capacity of nZVI at different pH and the M(n+1)+/Mn+ redox cycling between Fe or Co metal. The plausible degradation routes of TC were presented based on the detected intermediates. Overall, the synthesized heterogeneous nZVI/yCo3O4 composites can efficiently active PS at a wide pH range, and further broaden the application of Co-based catalysts in PS activation.

The article was titled 《Ultrasound-assisted synthesized BiFeO3 as FeOH+ promoted peroxymonosulfate activator for highly efficient degradation of tetracycline》, and you may find the article in Journal of Alloys and Compounds.SDS of cas: 826-36-8 The information in the text is summarized as follows:

A multiferroic BiFeO3 (BFO) catalyst was fabricated through a mild one-pot hydrothermal process with a bath-ultrasound assisted dissolution of Fe(NO3)3·9H2O for 30 min. X-ray photoemission spectroscopy revealed that the BFO (BFO-u) catalyst with US assisted dissolution of Fe(NO3)3·9H2O in the synthetic process exhibited high Fe2+ and OH- levels, which could be explained to be Fe3+ + H2O → Fe2+ + H+ + •OH. As a result, BFO-u catalyst activated potassium peroxymonosulfate (PMS) efficiently for degrading tetracycline hydrochloride. In particular, visible-light assisted activation of PMS over BFO-u catalyst exhibited the highest degradation rate constant, at 0.352 min-1. Species-trapping experiments revealed that the presence of PMS promoted the generation of •OH, •O-2 and 1O2 that all participated in degrading TCH, in which 1O2 was primarily contributed to the degradation Also, BFO-u catalyst was stable and recyclable and thus suitable for practical applications.

Kumar, Aditya; Prasad, Ankush; Sedlarova, Michaela; Pospisil, Pavel published an article on January 31 ,2019. The article was titled 《Organic radical imaging in plants: Focus on protein radicals》, and you may find the article in Free Radical Biology & Medicine.Formula: C9H17NO The information in the text is summarized as follows:

Biomol. (lipid and protein) oxidation products formed in plant cells exposed to photooxidative stress play a crucial role in the retrograde signaling and oxidative damage. The oxidation of biomols. initiated by reactive oxygen species is associated with formation of organic (alkyl, peroxyl and alkoxyl) radicals. Currently, there is no selective and sensitive technique available for the detection of organic radicals in plant cells. Here, based on the analogy with animal cells, immuno-spin trapping using spin trap, 5,5-dimethyl-1-pyrroline N-oxide (DMPO) was used to image organic radicals in Arabidopsis leaves exposed to high light. Using antibody raised against the DMPO nitrone adduct conjugated with the fluorescein isothiocyanate, organic radicals were imaged by confocal laser scanning microscopy. Organic radicals are formed predominantly in the chloroplasts located at the periphery of the cells and distributed uniformly throughout the grana stack. Characterization of protein radicals by standard immunol. techniques using anti-DMPO antibody shows protein bands with apparent mol. weights of 32 and 34 kDa assigned to D1 and D2 proteins and two protein bands below the D1/D2 band with apparent mol. weights of 23 and 18 kDa and four protein bands above the D1/D2 band with apparent mol. weights of 41, 43, 55 and 68 kDa. In summary, imaging of organic radicals by immuno-spin trapping represents selective and sensitive technique for the detection of organic radicals that might help to clarify mechanistic aspects on the role of organic radicals in the retrograde signaling and oxidative damage in plant cell.

SDS of cas: 826-36-8 And the article was included in Science of the Total Environment on April 10 ,2019. The article conveys some information:

Herein, the application of a novel acid mine drainage-based nanoscale zero valent iron (AMD-based nZVI) for the remediation of nitrate and norfloxacin (NOR) was studied. Exptl. results indicated that the catalytic reactivity of AMD-based nZVI toward nitrate reduction was superior to that of iron salt-based nanoscale zero valent iron (Iron salt-based nZVI). The presence of ultrasound irradiation could significantly enhance the reactivity toward both the nitrate reduction and NOR oxidation processes. The optimal efficiencies of nitrate and NOR by AMD-based nZVI/US process could be kept 96 and 94% within 120 min, resp. Ammonia was identified as a major product in nitrate reduction process, while three oxidation products were observed in NOR degradation process. Both reduction reaction of nitrate from AMD-based nZVI and oxidation reaction of NOR from US-assisted Fenton system might be involved in AMD-based nZVI/US process. The AMD-based nZVI/US process showed a better performance on the removal of NOR compared with that of nitrate. The findings of the present work could be as a guide and show that AMD-based nZVI/US process is feasible for the remediation of both nitrate and NOR in real wastewater.

Wang, Xiaolei; Ding, Yingzhi; Dionysiou, Dionysios D.; Liu, Cun; Tong, Yunping; Gao, Juan; Fang, Guodong; Zhou, Dongmei published their research in Science of the Total Environment on December 20 ,2020. The article was titled 《Efficient activation of peroxymonosulfate by copper sulfide for diethyl phthalate degradation: Performance, radical generation and mechanism》.SDS of cas: 826-36-8 The article contains the following contents:

Copper-containing minerals have been extensively used in Fenton-like processes for degradation of pollutants and have exhibited great potential for environmental remediation. This work reports the first use of copper sulfide (CuS), a typical Cu-mineral, for the activation of peroxymonosulfate (PMS) for pollutant degradation; the study also elucidates the underlying mechanism of these processes. Copper sulfide effectively activated PMS to degrade di-Et phthalate (DEP). ESR, free radical quenching, XPS, X-ray diffraction analyses and DFT calculations confirmed that Ξ Cu (I)/ ΞCu (II) cycling on the surface of CuS provided the main pathway to activate PMS to produce highly oxidative species. Unlike conventional sulfate radical-based PMS activation processes, hydroxyl radical (·OH) were found to be the dominant radical in the tested CuS/PMS system, which performed more efficiently than an alternative ·OH-based oxidation system (CuS/H2O2) for DEP degradation In addition, the presence of anions such Cl- and NO-3 has limited inhibition effects on DEP degradation Overall, this study provides an efficient pathway for PMS-based environmental remediation as well as a new insight into the mechanism of PMS activation by Cu-containing minerals.

(RuBpy3)2+-bisterpyridine-based metallacycle T photosensitizer was prepared by a facile single-step self-assembly process. Supramol. self-assembly strategy greatly improved metallacycle T’s photosensitized ability due to its enhanced light-harvesting capability, smaller energy gap (ΔEST) between lowest excited singlet state (S1) and lowest excited triplet state (T1) along with excellent solubility which exhibiting higher efficiency for singlet oxygen (1O2) production than the ligand L and its pendant [(RuBpy3)2+·2PF6-]. In the practical photo-driven degradation of sulfur mustard simulant (2-chloroethyl Et sulfide, CEES), full conversion of toxic CEES to nontoxic CEESO was achieved by metallacycle T with an extremely fast lifetime of 90 s (half lifetime t1/2 = 25 s) and 100% selectivity (without formation of highly toxic CEESO2), while ligand L and [(RuBpy3)2+·2PF6-] needed 130 s and 330 s, resp.

Product Details of 826-36-8On May 3, 2022 ,《Marine colloids promote the adaptation of diatoms to nitrate contamination by directional electron transfer》 appeared in Environmental Science & Technology. The author of the article were Kang, Weilu; Yu, Fubo; Wang, Shuting; Hu, Xiangang. The article conveys some information:

Nitrate contamination from human activities (e.g., domestic pollution, livestock breeding, and fertilizer application) threatens marine ecosystems and net primary productivity. As the main component of primary productivity, diatoms can adapt to high nitrate environments, but the mechanism is unclear. We found that electron transfer from marine colloids to diatoms enhances nitrogen uptake and assimilation under visible-light irradiation, providing a new pathway for nitrogen adaptation. Under irradiation, marine colloids exhibit semiconductor properties (e.g., the separation of electron-hole pairs) and can trigger the generation of free electrons and singlet oxygen. They also exhibit electron acceptor and donor properties, with the former being stronger than the latter, reacting with polysaccharides in extracellular polymeric substances (EPSs) under high nitrogen stress, enhancing the elasticity and permeability of cells, and promoting nitrogen assimilation and electron transfer to marine diatom EPSs. Electron transfer promotes extracellular-to-intracellular nitrate transport by upregulating membrane nitrate transporters and nitrate reductase. The upregulation of anion transport genes and unsaturated fatty acids contributes to nitrogen assimilation. We estimate that colloids may increase the nitrate uptake efficiency of marine diatoms by 10.5-82.2%. These findings reveal a mechanism by which diatoms adapt to nitrate contamination and indicate a low-cost strategy to control marine pollution.

《Molecular Orientation and Dynamics of a Derivative of 2,2,6,6-Tetramethyl-1-Piperidinyloxyl Radical with a Large Substituent Group Dispersed in 1D-Nanochannels of 2,4,6-Tris(4-Chlorophenoxy)-1,3,5-Triazine Crystal》 was written by Kobayashi, Hirokazu; Odanaka, Yuki. Related Products of 826-36-8 And the article was included in Applied Magnetic Resonance on August 31 ,2020. The article conveys some information:

The mol. orientation and dynamics were examined for 4-acetamido-2,2,6,6-tetramethyl-1-piperidinyloxyl (4-acetamido-TEMPO) radicals, which have a larger substituent group than many other TEMPO radicals, dispersed in the one-dimensional (1D) nanochannel of 2,4,6-tris(4-chlorophenoxy)-1,3,5-triazine (CLPOT) with 4-substituted-2,2,6,6-tetramethylpiperidine (R-TEMP; R=OH or H). When TEMPOH (R=OH) was used as a spacer for dispersion in the CLPOT nanochannels, the mol. orientation of 4-acetamido-TEMPO in the CLPOT nanochannels was similar to that of other previously reported 4-substituted-TEMPO (4-X-TEMPO; X=OH, =O or OCH3) radicals. However, the activation energy for the rotational diffusion of 4-acetamido-TEMPO in the CLPOT nanochannels, estimated to be 11 kJ mol-1, was larger than that of other 4-X-TEMPO mols. (6-8 kJ mol-1). These results indicate that the mol. dynamics of 4-X-TEMPO in the CLPOT nanochannels can be controlled by the selection of a larger substituent X at the 4-position in 4-X-TEMPO (in this study, X=NHCOCH3), and also suggest an important concept for the design of new organic magnets.
