And the article contained the following:

Nowadays, most manufacturing memory devices are based on materials with elec. bistability (i. e., “0” and “1”) in response to an applied elec. field. Memory devices with multilevel states are highly desired so as to produce high-d. and efficient memory devices. Herein, we report the first multichannel strategy to realize a ternary-state memristor. We make use of the intrinsic sub-nanometer channel of pillar[5]arene and nanometer channel of a two-dimensional imine polymer to construct an active layer with multilevel channels for ternary memory devices. Low threshold voltage, long retention time, clearly distinguishable resistance states, high ON/OFF ratio (OFF/ON1/ON2=1 : 10 : 103), and high ternary yield (75 %) were obtained. In addition, the flexible memory device based on 2DPTPAZ+TAPB can maintain its stable ternary memory performance after being bent 500 times. The device also exhibits excellent thermal stability and can tolerate a temperature as high as 300 掳C. It is envisioned that the results of this work will open up possibilities for multistate, flexible resistive memories with good thermal stability and low energy consumption, and broaden the application of pillar[n]arene. The experimental process involved the reaction of 1,4-Dimethoxybenzene(cas: 150-78-7).Category: ethers-buliding-blocks

M.; Kassab, Shaymaa E. published an article.Application In Synthesis of 1,4-Dimethoxybenzene The title of the article was Structure-based design and synthesis of conformationally constrained derivatives of methyl-piperidinopyrazole (MPP) with estrogen receptor (ER) antagonist activity. And the article contained the following:

Nuclear Estrogen receptors (ER) are cytoplasmic proteins; translocated to the nucleus to induce transcriptional signals after getting bound to the estrogen hormone. ER activation implicated in cancer cell proliferation of female reproductive organs. Thus, the discovery of ER antagonists is a reliable strategy to combat estrogen-dependent breast cancer. Endometrial carcinoma is one of the complications encountered upon long-term therapy by selective estrogen receptor modulators (SERMs) like Tamoxifen (TMX) and Me piperidinopyrazole (MPP). Thus, the ER-full antagonist is a solution to improve the safety of this class of therapeutics during the treatment of breast cancer. We selected MPP as a lead structure to design conformationally constrained analogs. Structural rigidification is a proven strategy to transform the SERMs into full antagonists. Accordingly, we synthesized 7-methoxy-3-(4-methoxyphenyl)-4,5-dihydro-2H-benzo[g]indazoles (4), (6a-c), (8-12) along with the biphenolic counterparts (13-19) that are the anticipated active metabolites. The 4-nitrophenyl derivative (4) is with the most balanced profile regarding the in vivo anti-uterotrophic potential (EC50 = 4.160 渭M); and the cytotoxicity assay of the corresponding active metabolite (13) against ER+ breast cancer cell lines (MCF-7 IC50 = 7.200 渭M, T-47D IC50 = 11.710 渭M). The inconsiderable uterotrophic activities of the elaborated ER-antagonists and weak antiproliferative activity of the compound (13) against ovarian cancer (SKOV-3 IC50 = 29.800 渭M) highlighted it as a good start point to elaborate potential ER-full antagonists devoid of endometrial carcinoma. Extending the pendant chain that protrudes from the 2-(4-(substituted)-phenyl) ring of the new benzo-indazoles is recommended for enhancing the potency based on the binding mode of compound (13) in the ligand-binding domain (LBD) of ER. The experimental process involved the reaction of 1,4-Dimethoxybenzene(cas: 150-78-7).Application In Synthesis of 1,4-Dimethoxybenzene

And the article contained the following:

The production of volatile organic compounds (VOCs) acting against plant-parasitic nematodes has been characterized in different fungi; however, the role of VOCs emitted by Pochonia chlamydosporia in its trophic interaction with Meloidogyne incognita is still unknown. The aim of this study was to determine the effects of VOCs emitted by P. chlamydosporia strain Pc-10 on different stages (eggs, juveniles and female) of the M. incognita life cycle. Exposure of M. incognita eggs to VOCs released by Pc-10 resulted in a reduction up to 88% in the nematode egg hatching, when compared to the control treatments. The VOCs emitted by Pc-10 also attracted M. incognita second-stage juveniles (J2). Through gas chromatog.-mass spectrometry (GC-MS), three mols. were identified from the volatiles of the strain Pc-10, with 1,4-dimethoxybenzene being the major compound In tests performed in vitro, 1,4-dimethoxybenzene at a concentration of 1050渭g mL-1 inhibited M. incognita egg hatching by up to 78.7% compared to the control (0渭g mL-1) and attracted M. incognita J2 in all concentrations evaluated (1, 10, 100, 1000, and 10000渭g mL-1). The 1,4-dimethoxybenzene also showed fumigant and non-fumigant nematicidal activity against M. incognita. This compound presented lethal concentration for 50% (LC50) of M. incognita J2 ranged from 132 to 136渭g mL-1. Fumigation with 1,4-dimethoxybenzene (100 mg) reduced egg hatching by up to 89% and killed up to 86% of M. incognita J2 compared to the control (0渭g mL-1). In vivo, the VOCs produced by Pc-10, 1,4-dimethoxybenzene, and the combination of both (Pc-10 + 1,4-dimethoxybenzene) attracted the M. incognita J2, compared to the resp. controls. To the best of our knowledge, this is the first report on the attraction of M. incognita J2 and the toxicity to eggs and J2 by VOCs from P. chlamydosporia in which 1,4-dimethoxybenzene is the main toxin and attractant. The experimental process involved the reaction of 1,4-Dimethoxybenzene(cas: 150-78-7).Related Products of 150-78-7

On October 15, 2020, Tan, Chaoqun; Wu, Haotian; He, Huan; Lu, Xu; Gao, Haiying; Deng, Jing; Chu, Wenhai published an article.SDS of cas: 150-78-7 The title of the article was Anti-inflammatory drugs degradation during LED-UV365 photolysis of free chlorine: roles of reactive oxidative species and formation of disinfection by-products. And the article contained the following:

Light-emitting diode (LED) is environmentally friendly with longer life compared with traditionally mercury lamps. This study investigated the non-steroidal anti-inflammatory drugs (NSAIDs)- phenacetin (PNT) and acetaminophen (ACT)- removal during LED-UV (365 nm) photolysis of free available chlorine (FAC). Degradation of PNT and ACT during LED-UV365/FAC treatment at pH 5.5-8.5 followed the pseudo-first order kinetics. The presence of hydroxyl radicals (路OH), reactive chlorine species (RCS), and ozone (O3, transformed from O (3P)) were screened by using scavengers of ethanol (EtOH), tert-Butanol (TBA), and 3-buten-2ol, and 4-hydroxy-2,2,6,6-tetramethylpiperidine (TEMP), and quantified by competition kinetics with probing compounds of nitrobenzene (NB), benzoate acid (BA), 1,4-dimethoxybenzene (DMOB). Higher pH would lead to decrease of 路OH contribution and an increase of FAC contribution to PNT and ACT degradation It has been determined that the contribution of O3 to degradation of PNT and ACT was less than 5% for all pHs, and O3(P) reacts toward EtOH with second-order constant of 1.52 x 109 M-1s-1. LED-UV365/FAC system reduced the formation of five typical CX3-R type disinfection byproducts (DBPs) as well as the cytotoxicity and genotoxicity of water samples at pH 5.5 and 8.5, compared with FAC alone. The decrease of DBPs formation resulted from fast FAC decomposition upon LED-UV365 irradiation A feasible reaction pathway of DBPs formation in the LED-UV365/FAC system was examined with d. functional theory (DFT). For FAC decay during LED-UV365/FAC with effluent from wastewater, the residual FAC in 15 min was 0.8 mg/L (lower than limit of 0.2 mg/L) once initial FAC was 2.0 mg/L. The results indicate that more tests on the balance of target pollutant removal efficiency, residual FAC and cost should be explored in LED-UV365/FAC system for application.

On August 25, 2020, Antonopoulou, Maria; Ioannidis, Nikolaos; Kaloudis, Triantafyllos; Triantis, Theodoros M.; Hiskia, Anastasia published an article.Formula: C8H10O2 The title of the article was Kinetic and mechanistic investigation of water taste and odor compound 2-isopropyl-3-methoxy pyrazine degradation using UV-A/Chlorine process. And the article contained the following:

The present study was launched as a continuation of global efforts to tackle problems associated with two important aesthetic characteristics, taste and odor (T&O), of drinking water. The UV-A/Chlorine process, a promising advanced oxidation process (AOP), was evaluated for the first time for the removal of 2-isopropyl-3-methoxy pyrazine (IPMP), a widely reported compound in the literature that causes unpleasant taste and odor when present in water at or below the ng L-1 level. It was found that the studied process was efficient for the removal of IPMP in both ultrapure and drinking water. The initial chlorine dosage influenced significantly the degradation efficiency under initial neutral pH values. Degradation efficiency of IPMP was slightly inhibited by using drinking water as matrix. Scavenging experiments highlighted the significant role of various reactive species (e.g. HO路, ClO路, Cl路, Cl2路-) generated during the process that have not been studied comprehensively until now. In addition, the significant role of HO路 was further verified by ESR spectroscopy (EPR) experiments Overall, the formation of diverse radicals during the UV-A/Chlorine treatment enhanced the degradation of IPMP, promoting mainly the formation of hydroxy, hydroperoxy and dealkylated derivatives In contrast, chlorinated byproducts were only identified in traces. The experimental process involved the reaction of 1,4-Dimethoxybenzene(cas: 150-78-7).Formula: C8H10O2

On June 30, 2022, Yuan, Donghai; Liu, Guangyu; Qi, Fei; Wang, Jinggang; Kou, Yingying; Cui, Yanqi; Bai, Minghui; Li, Xinyu published an article.SDS of cas: 150-78-7 The title of the article was Kinetic study on degradation of micro-organics by different UV-based advanced oxidation processes in EfOM matrix. And the article contained the following:

Effluent organic matter (EfOM) contains a large number of substances that are harmful to both the environment and human health. To avoid the neg. effects of organic matter in EfOM, advanced treatment of organic matter is an urgent task. Four typical oxidants (H2O2, PS, PMS, NaClO) and UV-combined treatments were used to treat micro-contaminants in the presence or absence of EfOM, because the active radical species produced in these UV-AOPs are highly reactive with organic contaminants. However, the removal efficiency of trace contaminants was greatly affected by the presence of EfOM. The degradation kinetics of two representative micro-contaminants (benzoic acid (BA) and para chlorobenzoic acid (pCBA)) was significantly reduced in the presence of EfOM, compared to the degradation kinetics in its absence. Using the method of competitive kinetics, with BA, pCBA, and 1,4-dimethoxybenzene (DMOB) as probes, the radicals (HO路, SO4-路, ClO路) proved to be the key to reaction species in advanced oxidation processes. UV irradiation on EfOM was not primarily responsible for the degradation of micro-contaminants. The second-order rate constants of the EfOM with radicals were determined to be (5.027 卤 0.643) x 102 (SO4-路), (3.192 卤 0.153) x 104 (HO路), and 1.35 x 106 (ClO路) (mg C/L)-1 s-1. In addition, this study evaluated the production of three radicals based on the concept of Rct, which can better analyze its reaction mechanism.
