On August 31, 2022, Karakurt, Huseyin; Kartal, Ozlem Esen published an article.Formula: C3H6O4 The title of the article was Removal of Reactive Red 120 using immobilized TiO2 in the presence of UV light. And the article contained the following:

Removal of Reactive Red 120 (RR120) dye in aqueous solution was investigated using immobilized TiO2 in the presence of UV light. TiO2 was deposited onto microscope slides by heat attachment method. SEM analyses confirmed that all microscope slides were coated with TiO2 particles completely after single, two, three and four layers coating. The removal efficiency increased with repetitive coating up to three layers. The highest removal efficiency of 94% was obtained at pH 3 within 300 min of reaction time. Complete removal was observed with 5 and 10 mg dm-3 dye concentrations whereas removal efficiency decreased from 96 to 52% when initial RR120 concentration increased 15 mg dm-3 to 30 mg dm-3. The results of nonlinear optimization showed that the kinetics of removal of RR120 in the range of concentration studied described by L-H kinetic expression. The experiments conducted with radical scavengers indicated that hydroxyl radicals and photogenerated hole and electrons were main reactive species in photocatalytic removal of RR120. The photonic efficiency of immobilized system was lower than that of suspended system. Minor drop (6%) in the removal of RR120 with three layers coated slide after four consecutive cycles of 300 min indicated the reusability and stability of coated slides. A possible degradation mechanism for degradation of RR120 was proposed according to detected intermediate compounds Mineralization of RR120 was monitored by generation of NO3- and SO42- ions in solution during photocatalytic reaction. The experimental process involved the reaction of 2,3-Dihydroxypropanoic acid(cas: 473-81-4).Formula: C3H6O4

On January 31, 2022, Sharma, Preeti; Madan, Jaya; Pandey, Rahul; Sharma, Rajnish published an article.Related Products of 143-10-2 The title of the article was Reliability analysis of cost-efficient CH3NH3PbI3 based dopingless tunnel FET. And the article contained the following:

Electrostatically-doped TFETs (ED-TFETs) are amongst the most widely used cost-efficient steeper devices due to the use of charge-plasma technique and tunneling mechanism. However, the reliability anal. of ED-TFETs is considered an important concern for the research community. Most studies have only focused on improving the performance of ED-TFETs such as dopingless (DL)-TFET in terms of on-current (ION), subthreshold swing (SS) and threshold voltage (Vth), rather than investigating the reliability issues. In this context, the aim of our work is to investigate the reliability anal. of our previously reported methyl-ammonium lead tri-iodide materials based DL-TFET (MAPbI3-DL-TFET). The influence of interface trap charges, shallow and deep defects on the elec. and analog performance of MAPbI3-DL-TFET has been analyzed using the Silvaco ATLAS tool at room temperature Extensive results produced show that deep-level (Gaussian) defects impact the performance of the device prominently while the tail defects affect the device performance insignificantly. The present findings showed that the donor/acceptor trap charges impact the device in the subthreshold region considerably, while in the superthreshold region the impact of trap charges is marginal. In our view, these results emphasize the reliability anal. of MAPbI3-DL-TFET for the very first time. We hope that our research will be useful and valuable for DL-TFET manufacturers. The experimental process involved the reaction of 1-Decanethiol(cas: 143-10-2).Related Products of 143-10-2

On June 9, 2021, Jiang, Peng; Li, Xue-Wen; Wang, Jin-An; Zhou, Xiao-Long published an article.Name: 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol The title of the article was Kinetic and mechanism studies on the photodegradation of cold-rolling emulsion wastewater by the UV/H2O2 process. And the article contained the following:

The UV/H2O2 process was employed to purify cold-rolling emulsion wastewater (CREW). The degradation of CREW was mainly attributed to the combined UV/H2O2 process and exhibited pseudo-first-order reaction kinetics. The reaction parameters, including the H2O2 dosage, initial pollutant concentration, initial pH, UV intensity, and inorganic anions, were found to influence the removal efficiency of COD (COD) and reaction rates. In addition, the optimal exptl. conditions were determined: H2O2 dosage of 0.2 mol/L, initial pH of 9.13, and UV intensity of 4.0 mW/cm2. The final residual COD concentration decreased from 3573 mg O2/L to 67 mg O2/L, and the treated wastewater complies with the wastewater discharge standards in China (COD concentration of 80 mg O2/L) and can be discharged. Meanwhile, •OH was identified as the primary reactive radical in the process. Sodium dodecyl sulfonate (SDS) and hexahydro-1,3,5-tris(hydroxyethyl)-s-triazine (BK) were selected as representative pollutants in CREW to explore the degradation mechanism. The products generated were identified by liquid chromatog.-mass spectrometry (LC-MS) and gas chromatog.-mass spectrometry (GC-MS). Potential degradation pathways were proposed and discussed. The operational cost is 0.115 USD/L, which was calculated for the best conditions. The experimental process involved the reaction of 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol(cas: 4719-04-4).Name: 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol

On January 1, 2022, Montesantos, Nikolaos; Fini, Mahdi Nikbakht; Muff, Jens; Maschietti, Marco published an article.SDS of cas: 4719-04-4 The title of the article was Proof of concept of hydrothermal oxidation for treatment of triazine-based spent and unspent H2S scavengers from offshore oil and gas production. And the article contained the following:

The feasibility of the hydrothermal oxidation of a wastewater derived from H2S scavenging operations, carried out in a topside offshore oil and gas installation, was demonstrated. The feed characterization showed the presence of mainly unreacted triazine (unspent scavenger), monoethanolamine and dithiazine (spent scavengers). The spent and unspent scavengers (SUS) were subjected to hydrothermal oxidation in a batch reactor at approx. 200°C (low temperature, LT) and 350°C (high temperature, HT), using oxygen in excess. The experiments were performed for six reaction times at each temperature, in the range 3 to 360 min at LT and 1 to 120 min at HT. Diluted SUS (COD around 30 g/kg) was used as reactor feed. The three main compounds of the SUS were not found in any of the oxidation products, which means they are fast converted. COD reductions up to 84% and 98% were obtained at LT and HT, resp. A rate equation of second order with respect to the COD was found suitable to represent the rate of disappearance of COD, with the rate constant at HT approx. 70 times higher than at LT. The extensive anal. carried out on the reaction products showed the presence of C1-C4 carboxylic acids, pyridines and pyrazines as intermediate oxidation products. A clear trend towards complete mineralization of organic nitrogen to ammonium, except for small amounts of nitrate at LT, and of organic sulfur towards sulfate, was observed The experimental process involved the reaction of 2,2′,2”-(1,3,5-Triazinane-1,3,5-triyl)triethanol(cas: 4719-04-4).SDS of cas: 4719-04-4

On September 15, 2021, Chen, Zhanghao; Teng, Ying; Huang, Liuqing; Mi, Na; Li, Chen; Ling, Jingyi; Gu, Cheng; Jin, Xin published an article.COA of Formula: C8H8O3 The title of the article was Rapid photo-reductive destruction of hexafluoropropylene oxide trimer acid (HFPO-TA) by a stable self-assembled micelle system of producing hydrated electrons. And the article contained the following:

Herein, we developed a self-assembled micelle system to decompose/defluorinate HFPO-TA (an alternative perfluoroalkyl substances (PFASs)) under ambient conditions by using three hydroxyphenylacetic acids (2-HPA, 3-HPA, 4-HPA) as hydrated electron precursors under UV irradiation, and using cationic surfactant cetyl tri-Me ammonium bromide (CTAB) to construct the micelle structure. The formed HPAs/CTAB/HFPO-TA micelles were well characterized. All the three micelle systems could efficient destruct HFPO-TA, while 2-HPA/CTAB/HFPO-TA self-assembled micelle showed the best stability under a wide pH range from 4 to 10 attributing to its tighter micelle structure and lower surface charge d. Moreover, natural organic matter (<10 mg L-1) plays little inhibition for the 2-HPA/CTAB/HFPO-TA system. This novel ternary micelle system not only maintains the high efficiency under the conditions of oxygen enrichment, but also keeps well performance in varied pH conditions. The high decomposition/defluorination efficiency and anti-interference capability of the 2-HPAs/CTAB/HFPO-TA micelle system make it a promising technol. for treating the PFASs contaminating wastewater. The experimental process involved the reaction of 3-Hydroxyphenylacetic acid(cas: 621-37-4).COA of Formula: C8H8O3

Kumar, Naresh; Gorai, Biswajit; Gupta, Saurabh; Shiva; Goel, Nidhi published an article in 2021, the title of the article was Extrapolation of hydroxytyrosol and its analogues as potential anti-inflammatory agents.Recommanded Product: 621-37-4 And the article contains the following content:

Discovery of potential lead mol. is a challenging, and complex process which require lots of money, patience, and manpower. Human beings are using natural products, predominantly secondary metabolites, for this purpose since ancient time and they are still working on them as a potent source for drug discovery due to their wide structural diversity. Phenolic phytochems. such as hydroxytyrosol and tyrosol are natural antioxidant and involved in many biol. disease cure. Herein, we have carried out the quantum chem. calculations for conformational anal., geometry optimization and computation of electronic as well as optical properties of hydroxytyrosol and its analogs (1a-1k) in terms of d. functional theory by using Gaussian 09 program suite. The eventual charge transfer within the mols. has been confirmed by the anal. of frontier MOs. The mol. docking studies of 1a-1k with cyclooxygenase-2 showed the noticeable binding affinity as compared to other nonsteroidal anti-inflammatory drugs viz. aspirin, naproxen and celecoxib. Computation of pharmacokinetics and pharmacol. properties confirmed the lead/drug like potential of these screened mols. Furthermore, the mol. dynamics simulation of best three docked ligands (1f, 1h and 1k)-receptor complex and their binding free energy calculations reveals that these mols. bind in the catalytic cavity of cyclooxygenase-2 and found stable during the 100 ns of simulation. The experimental process involved the reaction of 3-Hydroxyphenylacetic acid(cas: 621-37-4).Recommanded Product: 621-37-4
