On February 1, 2016, Hopp, Jens; Trieloff, Mario; Ott, Ulrich published an article.Computed Properties of 97-09-6 The title of the article was I-Xe ages of enstatite chondrites. And the article contained the following:

In order to elucidate the early thermal history of enstatite chondrite parent bodies we determined 129I-129Xe whole rock ages of enstatite chondrites (5 EH, 2 EL, one EH impact melt) relative to the Shallowater reference meteorite (4562.3 ± 0.4 Ma, all errors are 1σ). I-Xe ages of both EL6 chondrites (LON 94100: -4.38 ± 0.60 Ma and Neuschwanstein: -3.87 ± 0.73 Ma – neg. sign indicates ages younger than Shallowater) agree well with data of other EL6 chondrites. LON 94100 displayed a second isochron at lower temperatures equivalent to a younger age of -5.25 ± 1.17 Ma, perhaps reflecting different retention temperatures of resp. carrier phases during sequential cooling. The enstatite chondrites Abee (EH4), Indarch (EH4), EET 96135 (EH4/5) and St. Marks (EH5) encompass a I-Xe age range of +0.57 ± 1.05 Ma (EET 96135 #1) to -0.45 ± 0.72 Ma (Abee), again in agreement with previously reported ages of EH chondrites. Only the age of St. Marks differs strongly from previously reported younger ages, now being more in accordance with other members of the EH clan. The EH3 chondrite Sahara 97096 showed the youngest I-Xe age of -7.87 ± 0.46 Ma distinctly younger than other I-Xe ages of EH chondrites, including other EH3s. Due to the apparent high retention temperature of the I-Xe system in enstatite (estimated >800 °C) this young age implies a later resetting of the I-Xe system by a severe thermal, likely impact-induced, event. The EH impact melt LAP 02225 records a similarly young thermal event. Though no isochron relationship could be established, the data fall within an apparent I-Xe age range of +5 to +15 Ma, similar to Sahara 97096. Overall, EH chondrite parent body experienced a thermal history determined by a complex interplay between impact disturbances and parent body metamorphism. The experimental process involved the reaction of 3-Nitro-4-chlorobenzenesulfonamide(cas: 97-09-6).Computed Properties of 97-09-6

On August 15, 2021, Zhang, Lili; Zhang, Cheng; Lian, Keting; Liu, Chongxuan published an article.SDS of cas: 144-80-9 The title of the article was Effects of chronic exposure of antibiotics on microbial community structure and functions in hyporheic zone sediments. And the article contained the following:

Microbial communities in hyporheic zones (HZ) provide vital biogeochem. functions such as contaminant degradation for river ecosystems. Antibiotics are contaminants that have been increasingly detected in HZ sediments. In this study, sediments from different HZ locations in a contaminated river, Maozhou river, China were sampled and analyzed using qPCR and high-throughput sequencing to investigate the effect of antibiotic contamination on microbial community structures and functions in HZ sediments. Results indicated that types and concentrations of antibiotics in HZ sediments were heterogeneously distributed that were largely consistent with the distribution of antibiotic sources. Sediments near animal farm and hospital contained higher antibiotic concentrations compared with those from mainstream. The distribution of ARGs was well correlated with antibiotics. Bacterial indicator genera indicating differences between mainstream area and other sampling areas were pos. correlated with antibiotics, suggesting the influences of antibiotics on reshaping microbial community structures. PICRUSt revealed pos. relationships between antibiotics and predicted functional genes involved in defense, signal transduction, and recombination and repair. This imply the defensive response of microbial communities on antibiotic attack. These results indicated that antibiotic contamination in the watershed posed a potential risk on HZ microbial community structures and functions, which may further threaten river ecosystem functions. The experimental process involved the reaction of N-((4-Aminophenyl)sulfonyl)acetamide(cas: 144-80-9).SDS of cas: 144-80-9

On January 31, 2020, Liang, Bin; Yun, Hui; Kong, Deyong; Ding, Yangcheng; Li, Xiangkai; Vangnai, Alisa S.; Wang, Aijie published an article.Quality Control of 1,3-Diphenylurea The title of the article was Bioaugmentation of triclocarban and its dechlorinated congeners contaminated soil with functional degraders and the bacterial community response. And the article contained the following:

Partial removal of haloarom. antimicrobial triclocarban (TCC) during wastewater treatment caused the final introduction of residual TCC into soils. Bioaugmentation has been proposed for the biodegradation of TCC and its dechlorinated congeners 4,4′-dichlorocarbanilide (DCC) and carbanilide (NCC) in soil. The isolated TCC-degrading strain Ochrobactrum sp. TCC-2 and chloroanilines-degrading strain Diaphorobacter sp. LD72 were used to study the removal efficiency of TCC, DCC and NCC mixture and their chloroanilines intermediates, resp. The potential degradation competition between TCC and its dechlorinated congeners, and the response of bacterial community during the bioremediation were also investigated. The biodegradation of DCC and TCC was significantly enhanced for soil with inoculums compared with sterilized and natural soils. Chloroanilines products could also be effectively removed. For the degradation of combined substrates in the aqueous medium, NCC had neg. effect on the degradation of TCC and DCC, while TCC and DCC neg. influenced each other. The bioaugmentation with two degraders obviously changed the phylogenetic composition and function of indigenous soil microbiome. Importantly, the inoculated degraders could be maintained, suggesting their adaptability and potential application in bioaugmentation for such recalcitrant contaminants. This study offers new insights into the enhanced bioremediation of TCC and its dechlorinated congeners contaminated soils by the bioaugmentation of functional degraders and the structure and function response of the indigenous soil microbiome to the bioremediation process. The experimental process involved the reaction of 1,3-Diphenylurea(cas: 102-07-8).Quality Control of 1,3-Diphenylurea

On January 15, 2021, Sakurai, Karen Sayuri Ito; Pompei, Caroline Moco Erba; Tomita, Ines N.; Santos-Neto, Alvaro J.; Silva, Gustavo Henrique Ribeiro published an article.Application In Synthesis of N-((4-Aminophenyl)sulfonyl)acetamide The title of the article was Hybrid constructed wetlands as post-treatment of blackwater: An assessment of the removal of antibiotics. And the article contained the following:

New sanitation systems have been developed to treat, recover energy and nutrients, and permit reuse processes at the source of generation, minimizing water use and flow segregation. Thus, this study was carried out with the objective of evaluating the potential of hybrid constructed wetlands in the removal of organic matter, nutrients, pathogenic microorganisms, and 12 antibiotics from blackwater previously treated by an upflow anaerobic sludge blanket reactor. A hybrid system of constructed wetlands was used, comprised of a horizontal subsurface flow constructed wetland with a total volume of 0.60 m3 followed by a vertical subsurface flow constructed wetland with a total volume of 0.20 m3. Three different hydraulic retention times were comparatively tested (1.0, 2.0, and 3.0 days for the horizontal subsurface flow constructed wetland, and 1.1, 0.9, and 0.4 days for the vertical subsurface flow constructed wetland) in four distinct stages. The plant species used was Canna generalis. The results from this study demonstrate the potential of constructed wetlands as a suitable technol. for post-treatment of segregated domestic wastewater (anaerobically-digested blackwater). Efficient reduction of COD, BOD5, total nitrogen, and total phosphorus (74, 93, 50, and 61%, resp.) was achieved, with a hydraulic retention time of 3.0 and 1.1 days for horizontal and vertical subsurface flow constructed wetland, resp. (stage IV). The presence of ciprofloxacin was confirmed by chromatog. and mass spectrometric anal. in an average concentration of 442.6 ng. L-1 at the inflow of the horizontal subsurface flow constructed wetland, but was not observed at the outflow. The experimental process involved the reaction of N-((4-Aminophenyl)sulfonyl)acetamide(cas: 144-80-9).Application In Synthesis of N-((4-Aminophenyl)sulfonyl)acetamide

On August 31, 2021, Wang, Juan; Zhang, Peng-Li; Ansari, Mohammad Fawad; Li, Shuo; Zhou, Cheng-He published an article.COA of Formula: C8H10N2O3S The title of the article was Molecular design and preparation of 2-aminothiazole sulfanilamide oximes as membrane active antibacterial agents for drug resistant Acinetobacter baumannii. And the article contained the following:

A series of 2-aminothiazole sulfanilamide oximes were developed as new membrane active antibacterial agents to conquer the microbial infection. Benzoyl derivative 10c was preponderant for the treatment of drug-resistant A. baumannii infection in contrast to norfloxacin and exerted excellent biocompatibility against mammalian cells including erythrocyte and LO2 cell line. Meanwhile, it had ability to eradicate established biofilm to alleviate the resistance burden. Mechanism investigation elucidated that compound 10c was able to disturb the membrane effectively and inhibit lactic dehydrogenase, which led to cytoplasmic content leakage. The cellular redox homeostasis was interfered via the production of reactive oxygen and nitrogen species (RONS), which further contributed to respiratory pathway inactivation and reduction of GSH activity. This work indicated that 2-aminothiazole sulfanilamide oximes could be a promising start for the exploitation of novel antibacterial agents against pathogens. The experimental process involved the reaction of N-((4-Aminophenyl)sulfonyl)acetamide(cas: 144-80-9).COA of Formula: C8H10N2O3S

On June 30, 2022, Pu, Miao; Ailijiang, Nuerla; Mamat, Anwar; Chang, Jiali; Zhang, Qiongfang; Liu, Yifan; Li, Nanxin published an article.Name: N-((4-Aminophenyl)sulfonyl)acetamide The title of the article was Occurrence of antibiotics in the different biological treatment processes, reclaimed wastewater treatment plants and effluent-irrigated soils. And the article contained the following:

Reclaimed wastewater is increasingly being used for agricultural irrigation to address water scarcity, particularly in arid and semiarid areas. In this study, the occurrence and removal of 24 antibiotics were investigated in two wastewater treatment systems (WWTSs) and their irrigation areas located in the arid northwestern region of China. The different WWTSs included absorption-biodegradation (AB) + anaerobic-anoxic-oxic (AAO) and AAO + AAO + membrane bioreactor (MBR). Nineteen antibiotics were detected, with concentrations ranging from low to 60.8μg/L. The dominant antibiotic classes were quinolones (QNs) and macrolides (MLs) in winter, and MLs and sulfonamides (SAs) in summer. The AAO + AAO + MBR system exhibited better removal efficiencies for most antibiotics, improving their adsorption and biodegradation Except for ofloxacin (OFC) and norfloxacin (NFC), the concentrations of the detected antibiotics were higher in summer than in winter. However, the antibiotic removal efficiency increased by 2-141% in summer compared to winter due to the increase in microbial activity with temperature Even though reclaimed treatment water plants contributed to the removal of antibiotics, residual antibiotics still affected the soil environment after green irrigation. In irrigated soil, QNs were predominantly detected, with a maximum concentration of 150.9 ng/kg for NFC. An ecol. risk assessment showed that OFC, NFC, enrofloxacin, and lomefloxacin presented low or medium ecol. risks in at least two irrigated sites. Thus, more attention should be given to the reuse of reclaimed wastewater, as it may pose toxicity risks to organisms in the soil environment. The experimental process involved the reaction of N-((4-Aminophenyl)sulfonyl)acetamide(cas: 144-80-9).Name: N-((4-Aminophenyl)sulfonyl)acetamide
