In 2022,Shirase, Yuto; Matsumoto, Akinobu; Lim, Kean Long; Tryk, Donald A.; Miyatake, Kenji; Inukai, Junji published an article in ACS Omega. The title of the article was 《Properties and Morphologies of Anion-Exchange Membranes with Different Lengths of Fluorinated Hydrophobic Chains》.Recommanded Product: 1-Chloro-3-iodobenzene The author mentioned the following in the article:

An anion-exchange electrolyte membrane, QPAF(C6)-4, polymerized with hydrophobic 1,4′-bis(3-chlorophenyl)perfluorohexane and hydrophilic 6,6′-(2,7-dichloro-9H-fluorene-9.9-diyl)bis(N,N-dimethylhexan-1-amine) is phys. flexible and chem. stable. The drawbacks are relatively large water swelling and lower OH- conductivity at higher water uptakes, which are considered to be due to the entanglement of the flexible hydrophobic structure of the membrane. In this study, a QPAF(C4)-4 membrane was newly synthesized with shortened hydrophobic fluoroalkyl chains. Unexpectedly, QPAF(C4)-4 showed a higher water uptake and a lower bulk/surface conductivity than QPAF(C6)-4 possibly due to the decrease in hydrophobicity with a smaller number of fluorine atoms. The thermal stability of QPAF(C4)-4 was higher than that of QAPF(C6)-4, possibly due to the rigidity of the QAPF(C4)-4 structure. A higher mech. strength of QAPF(C6)-4 than that of QPAF(C4)-4 could be explained by the larger interactions between mols., as shown in the UV-visible spectrum. The interactions of mols. were understood in more detail with d. functional theory calculations Both the chem. structures of the polymers and the arrangements of the polymers in the membranes were found to influence the membrane properties. In the experiment, the researchers used many compounds, for example, 1-Chloro-3-iodobenzene(cas: 625-99-0Recommanded Product: 1-Chloro-3-iodobenzene)

In 2022,Nandi, Shantanu; Mondal, Shuvam; Jana, Ranjan published an article in iScience. The title of the article was 《Chemo- and regioselective benzylic C(sp3)-H oxidation bridging the gap between hetero- and homogeneous copper catalysis》.Electric Literature of C7H5IO2 The author mentioned the following in the article:

An expedient synthesis of privileged seven-membered lactones, dibenzo[c,e]oxepin-5(7H)-one through a highly chemoselective benzylic C(sp3)-H activation was disclosed. Remarkably, the formation of widely explored six-membered lactone via C(sp2)-H activation was suppressed under the present conditions. The reaction proceeded smoothly on use of inexpensive metallic copper catalyst and di-tert-Bu peroxide (DTBP). Owing to the hazards of stoichiometric DTBP, further, a sustainable metallic copper/rose bengal dual catalytic system coupled with mol. oxygen replacing DTBP was developed. A 1,5-aryl migration through Smiles rearrangement was realized from the corresponding diaryl ether substrates instead of expected eight-membered lactones. The present methodol. was scalable, applied to the total synthesis of cytotoxic and neuroprotective natural product alterlactone. The catalyst was recyclable and the reaction could be performed in a copper bottle without any added catalyst. The experimental process involved the reaction of 2-Iodobenzoic acid(cas: 88-67-5Electric Literature of C7H5IO2)

2-Iodobenzoic acid(cas: 88-67-5) belongs to organic iodides. Generally organic iodides can be divided into two classes of alkyl iodides and aryl iodides. Typical reactions of alkyl iodides include nucleophilic substitution, elimination, reduction, and the formation of organometallics.Electric Literature of C7H5IO2

Computed Properties of C6H5IOIn 2020 ,《Chi-MIC-share: a new feature selection algorithm for quantitative structure-activity relationship models》 was published in RSC Advances. The article was written by Li, Yuting; Dai, Zhijun; Cao, Dan; Luo, Feng; Chen, Yuan; Yuan, Zheming. The article contains the following contents:

Quant. structure-activity relationship models are used in toxicol. to predict the effects of organic compounds on aquatic organisms. Common filter feature selection methods use correlation statistics to rank features, but this approach considers only the correlation between a single feature and the response variable and does not take into account feature redundancy. Although the minimal redundancy maximal relevance approach considers the redundancy among features, direct removal of the redundant features may result in loss of prediction accuracy, and cross-validation of training sets to select an optimal subset of features is time-consuming. In this paper, we describe the development of a feature selection method, Chi-MIC-share, which can terminate feature selection automatically and is based on an improved maximal information coefficient and a redundant allocation strategy. We validated Chi-MIC-share using three environmental toxicol. datasets and a support vector regression model. The results show that Chi-MIC-share is more accurate than other feature selection methods. We also performed a significance test on the model and analyzed the single-factor effects of the reserved descriptors. In the experiment, the researchers used many compounds, for example, 3-Iodophenol(cas: 626-02-8Computed Properties of C6H5IO)

And the article was published in Polyhedron in 2019. Reference of 1-Iodo-4-methylbenzene The author mentioned the following in the article:

In this study, Pd nanoparticles supported on Metformin modified graphene oxide (GO-Met-Pd) is proposed as a green heterogeneous catalyst. The structural properties of the as-synthesized nanocatalyst were determined by X-ray diffraction (XRD), Fourier transformed IR (FT-IR) spectroscopy, transmission electron microscopy (TEM), field emission SEM (FESEM), energy dispersive X-ray spectroscopy (EDS), wavelength-dispersive X-ray spectroscopy (WDX) and inductively coupled plasma (ICP). Activity of the catalyst was investigated by focusing on the Suzuki-Miyaura coupling reaction and room-temperature reduction of 4-nitrophenol (4-NP), as model reactions. The catalyzed reactions provided high yields of biphenyl compounds through the Suzuki-Miyaura reaction and outlined highly efficient conversion of 4-NP to its reduced form. Moreover, no significant Pd leaching was detected in the reaction solutions and the catalyst could be recovered, at least, 6 times without any considerable loss of its catalytic activity.

《Photocatalytic CO2 reduction of C/ZnO nanofibers enhanced by an Ni-NiS cocatalyst》 was published in Nanoscale in 2020. These research results belong to Deng, Hongzhao; Xu, Feiyan; Cheng, Bei; Yu, Jiaguo; Ho, Wingkei. Safety of 1-Iodopyrrolidine-2,5-dione The article mentions the following:

The photocatalytic reduction of CO2 into valuable hydrocarbon fuels via solar energy is a promising strategy for carbon utilization. In the present paper, a hierarchical Ni-NiS/C/ZnO photocatalyst was prepared via the in situ photodeposition of compact Ni-NiS nanosheets onto C/ZnO electrospun nanofibers. The existence of metallic Ni and NiS was confirmed by XPS. Photoluminescence (PL) and time-resolved PL spectra revealed that the cocatalyst Ni-NiS enhanced the charge separation efficiency of the C/ZnO nanofibers. The as-prepared Ni-NiS/C/ZnO showed enhanced CO2 reduction activity, with CO and CH4 production rates 10 and 15 times greater than those of pristine C/ZnO under 350 W visible light illumination. The intermediates of CH3O-, HCHO, and HCOO- were detected by in situ Fourier transform IR spectroscopy, confirming that CO2 reduction is a complex reaction with multiple steps. The 13C isotopic tracer method proved that CH4 and CO were obtained from the reduction of CO2 rather than from other carbon species in the environment. The amorphous carbon in C/ZnO could promote optical absorption, improve conductivity and reduce the interfacial charge transport resistance. Ni-NiS improved the electron-hole-pair separation of the C/ZnO nanofibers. The observed enhancement in photocatalytic activity was largely attributed to higher light utilization and effective electron-hole separation This work proves that Ni-NiS is a promising cocatalyst to ZnO for photocatalytic CO2 reduction In the experiment, the researchers used many compounds, for example, 1-Iodopyrrolidine-2,5-dione(cas: 516-12-1Safety of 1-Iodopyrrolidine-2,5-dione)
