Witkowski, Bartlomiej;Jain, Priyanka;Gierczak, Tomasz research published 《 Aqueous chemical bleaching of 4-nitrophenol brown carbon by hydroxyl radicals; products, mechanism, and light absorption》, the research content is summarized as follows. The reaction of hydroxyl radicals (OH) with 4-nitrophenol (4NP) in an aqueous solution was investigated at pH = 2 and 9. The molar yield of the phenolic products quantified was ca. 0.2 at pH = 2 and 0.4 at pH = 9. The yield of 4-nitrocatechol (4NC) was higher at pH = 9. At the same time, a lower number of phenolic products was observed at pH = 9 due to irreversible reactions of some phenols formed at pH > 7. Mineralization investigated with a total organic carbon (TOC) analyzer showed that after 4NP was completely consumed, approx. 85% of the organic carbon remained in the aqueous solution Moreover, as inferred from the TOC measurements and the molar yields of the phenols formed, 65% of the organic carbon that remained in the aqueous solution was attributed to the non-aromatic products. The light absorption of the reaction solution between 250 and 600 nm decreased as a result of the OH reaction with 4NP. However, the 4NP solution showed a noticeable resistance to the chem. bleaching reaction investigated due to the formation of light-absorbing byproducts. This phenomenon effectively prolongs the timescales of the chem. bleaching of 4NP by OH by a factor of 3-1.5 at pH 2 and 9, resp. The exptl. data acquired indicated that both photolysis and the reaction with OH can be important processes for the removal of light-absorbing organic compounds from cloud water particles containing 4NP.

Williams, Alex;Langridge, Holly;Straathof, Angela L.;Fox, Graeme;Muhammadali, Howbeer;Hollywood, Katherine A.;Xu, Yun;Goodacre, Royston;de Vries, Franciska T. research published 《 Comparing root exudate collection techniques: An improved hybrid method》, the research content is summarized as follows. 1. Plant-microbe interactions are critical for ecosystem functioning and drive rhizosphere processes. Root exudates are an important soil carbon (C) input, as well as a mechanism for communication between plants and rhizosphere microbes, but are notoriously difficult to extract and characterize. Common methods produce either substantial noise from the soil or do not mimic natural systems. Optimizing methods for root exudate collection in soil is crucial for advancing our understanding of root-microbe interactions under changing environmental conditions.2. Hybrid root exudate collection methods, where plants are grown in soil and transferred to hydroponics for exudate collection after root washing, might offer an ecol. relevant alternative to existing approaches. However, this method causes potential root damage as well as osmosis and subsequent leaking of cell contents. Here, we assessed different root recovery periods after root washing and before hybrid root exudate collection, by comparing root exudate quantity and quality with both damaged root extracts and with leachates collected from the intact root-soil system. This was done across three common grassland species representing three functional groups.3. We found that root exudate profiles of the shortest recovery period (0 days) were similar to damaged root extracts and were very high in C. With an increasing period of root recovery, profiles were more similar to leachates collected from the intact root-soil system, and C concentrations decreased. While both hybrid and leachate collection methods separated species by their root exudate profiles, the hybrid method was less variable in terms of the amount of C measured and provided a more diverse and abundant metabolome with better identification of metabolites.4. Our results show that a recovery period after root washing of at least 3 days is critical to prevent root damage bias in hybrid collection methods, and that our hybrid method yields exudates that discriminate between species. Our data also suggest that exudates collected with this hybrid method are ecol. valid, which is vital for gaining a mechanistic understanding of their role in ecosystem functioning.

With the aim to develop a specific radioligand for imaging the cyclic nucleotide phosphodiesterase 5 (PDE5) in brain by positron emission tomog. (PET), seven new fluorinated inhibitors (3-9) were synthesized on the basis of a quinoline core. The inhibitory activity for PDE5 together with a panel of other PDEs was determined in vitro and two derivatives were selected for IC₅₀ value determination The most promising compound 7 (IC₅₀ = 5.92 nM for PDE5A), containing a 3-fluoroazetidine moiety, was further radiolabeled by aliphatic nucleophilic substitution of two different leaving groups (nosylate and tosylate) using [¹⁸F]fluoride. The use of the nosylate precursor and tetra-Bu ammonium [¹⁸F]fluoride ([¹⁸F]TBAF) in 3-methyl-3-pentanol combined with the addition of a small amount of water proved to be the best radiolabeling conditions achieving a RCY of 4.9 ± 1.5% in an automated procedure. Preliminary biol. investigations in vitro and in vivo were performed to characterize this new PDE5 radioligand. Metabolism studies of [¹⁸F]7 in mice revealed a fast metabolic degradation with the formation of radiometabolites which have been detected in the brain.

Wen, Jiaxin;Fu, Wenyang;Ding, Shihu;Zhang, Ying;Wang, Wei research published 《 Pyrogallic acid modified nanoscale zero-valent iron efficiently removed Cr(VI) by improving adsorption and electron selectivity》, the research content is summarized as follows. Pyrogallic acid (pyGA) was firstly introduced into nanoscale zero-valent iron (nZVI) synthesis process by sodium borohydride to obtain a new catalyst pyGA-nZVI. The characterization of the material indicated successful coating of pyGA on nZVI surface. pyGA-nZVI could completely remove 50 mg·L-1 Cr(VI) within 4 min, while only 41.4% of Cr(VI) was removed by nZVI within 30 min. The material presented high Cr(VI) removal in a wide pH range of 3-12. Ortho-phenol hydroxyl groups played a crucial role in synthesizing highly effective nZVI. Fe(II) and Fe0 were mainly responsible for Cr(VI) removal in the pyGA-nZVI and nZVI systems, resp. pyGA modification reduced the charge transfer resistance and enhanced electron transfer of nZVI. D. functional theory calculation indicated enhanced Cr(VI) adsorption on pyGA-nZVI. The reactivity of pyGA-nZVI toward H2O was hindered, increasing the electron selectivity for Cr(VI) removal. This article provides a new strategy for synthesizing highly reactive nZVI using polyphenols to remove Cr(VI).

B.;Jeppesen, Lone;Sauerberg, Per research published 《 1,2,5-Thiadiazole Analogs of Aceclidine as Potent m₁ Muscarinic Agonists》, the research content is summarized as follows. The acetyl group of the muscarinic agonist aceclidine (I) was replaced by various 1,2,5-thiadiazoles to provide a new series of potent m₁ muscarinic agonists II. Optimal m₁ muscarinic agonist potency was achieved when the 1,2,5-thiadiazole substituent was either a butyloxy or a butylthio group (II; R = OBu, SBu). Although 1,2,5-oxadiazole III and pyrazine IV are iso-π-electronic with 1,2,5-thiadiazole I (R = OBu) both analogs were substantially less active than I (R = OBu). Compounds with high muscarinic affinity and/or m₁ muscarinic agonist efficacy were also obtained when the 3-oxyquinuclidine moiety of I (R = OBu, SPr) was replaced by ethanolamines, hydroxypyrrolidines, hydroxyazetidine, hydroxyisotropanes, or hydroxyazanorbornanes. The structure-activity data support the participation of the oxygen or sulfur atom in the substituent on the 1,2,5-thiadiazole in the activation of the m₁ receptor. Several of these new 1,2,5-thiadiazoles have m₁ agonist efficacy, potency, and selectivity comparable to those of xanomeline (V) in the muscarinic tests investigated.

Aluminum often requires protective coatings to prevent corrosion. The aluminum alloy substrate usually needs pretreatment to minimize, stabilize or convert the surface oxide in order to achieve adequate coating adhesion. The electrodeposited Ni-P coating is a promising candidate as a protective coating due to its easy fabrication and excellent performance. This study comprehensively investigates the pretreatment of zincating and anodizing on 6061 aluminum alloy, and systematically discusses their influence on the electrodeposited Ni-P coatings. The crystal structure and elemental composition were investigated for interlayers and Ni-P coatings subsequently, while morphologies of the coating surface and cross-section were also determined The results revealed similar phase composition for differently pretreated Ni-P coatings, while distinct nodule featured morphol. was observed for anodized Ni-P coating. It was found that anodized Ni-P coatings had the best performance due to its superior coating adhesion, wear-resistance, and corrosion resistance. In contrast, severe wear damage was occurred to zincated Ni-P coatings due to its inferior microstructure and weak zinc interlayer. Lastly, the influence of anodizing pretreatment on the coating microstructure is discussed, and a model is proposed for Ni-P electrodeposition employing anodizing pretreatment.

Allylboronic acid pinacol ester is an allylation reagent that is used to produce aldehydes from ketones. It reacts with water, yielding the desired product and formaldehyde as a byproduct. The reaction proceeds through a sequence of steps, in which the boronate ester first reacts with water to form an allylboronate ion and hydrogen gas. This intermediate then reacts with potassium t-butoxide to produce the desired allyl alcohol and potassium borohydride. Finally, the palladium complex catalyst reduces the carbonyl group of the starting material, converting it into an aldehyde. Allylboronic acid pinacol ester is commercially available as a white solid, but can also be synthesized from 2-chloro-5-pinacolylborane (pinacol) in high yield using catalytic cross coupling reactions., Quality Control of 72824-04-5
