And the article was published in Chemical Physics in 2019. Application In Synthesis of 1-Iodopyrrolidine-2,5-dione The author mentioned the following in the article:

Some halogen bonded complexes of N-iodosuccinimide (NIS) with the nitrogen atoms at the donor and acceptor positions have been investigated by 14N NQR (NQR) spectroscopy. The data are analyzed in view of the change of the principal values of the quadrupole coupling tensor produced by halogen bonding. The results show that the deformation of the nitrogen electron orbitals is in the presently studied halogen bonded systems comparable to the one observed in strong hydrogen bonded systems. The order in which the strength of the halogen bond acceptor increases is determined A possible iodine displacement to a position, which is closer to the acceptor nitrogen atom than to the donor nitrogen atom may occur in the complex NIS-(3-picoline). In all studied complexes the deformation of the nitrogen electron orbitals caused by the halogen bond decreases with increasing temperature at both the donor and acceptor nitrogen positions. In the experiment, the researchers used 1-Iodopyrrolidine-2,5-dione(cas: 516-12-1Application In Synthesis of 1-Iodopyrrolidine-2,5-dione)

Aftab, Umair’s team published research in RSC Advances in 2020 | CAS: 516-12-1

《Nickel-cobalt bimetallic sulfide NiCo2S4 nanostructures for a robust hydrogen evolution reaction in acidic media》 was written by Aftab, Umair; Tahira, Aneela; Mazzaro, Raffaello; Morandi, Vittorio; Ishaq Abro, Muhammad; Baloch, Muhammad Moazam; Yu, Cong; Ibupoto, Zafar Hussain. Application In Synthesis of 1-Iodopyrrolidine-2,5-dione And the article was included in RSC Advances in 2020. The article conveys some information:

In this study, we have designed a facile strategy by tailoring the concentration of precursors to successfully obtain nickel-cobalt bimetallic sulfide (NiCo2S4) using a simple hydrothermal method. The morphol. of the newly prepared NiCo2S4 comprised a mixture of microparticles and nanorods, which were few microns in dimension. The crystallinity of the composite sample was found to be excellent with a cubic phase. The sample that contained a higher amount of cobalt compared to nickel and produced single-phase NiCo2S4 exhibited considerably improved HER performance. The variation in the salt precursor concentration during the synthesis of a material is a simple methodol. to produce a scalable platinum-free catalyst for HER. The composite sample produced a c.d. of 10 mA cm-2 at an overpotential of 345 mV. Also, it exhibited a Tafel value of 60 mV dec-1, which predominantly ensured rapid charge transfer kinetics during HER. CN-21 was highly durable and stable for 30 h. The obtained results reveal that our developed NiCo2S4 catalyst has a high d. of active edges, and it is a non-noble metal catalyst for the hydrogen evolution reaction. The present findings provide an alternative strategy and an active nonprecious material for the development of energy-related applications. The experimental process involved the reaction of 1-Iodopyrrolidine-2,5-dione(cas: 516-12-1Application In Synthesis of 1-Iodopyrrolidine-2,5-dione)

Smolkin, Boris’s team published research in ACS Omega in 2022 | CAS: 516-12-1

In 2022,Smolkin, Boris; Levi, Noam; Chen, Ravit published an article in ACS Omega. The title of the article was 《Efficient Decontamination of HD by an Electrophilic Iodine/Carboxylate Composite as an Active Sorbent》.HPLC of Formula: 516-12-1 The author mentioned the following in the article:

The development of new and efficient decontamination methods has become more relevant in recent years, especially with regard to solid-based decontamination and detoxification systems. The majority of powders used today are dealing with the phys. adsorption of chem. warfare agents (CWAs) and their removal from sites without actively destroying them. In this work, we have designed and developed an active solid composite matrix combining organic carboxylate salts and N-iodosuccinimide (NIS) for HD decontamination via oxidation All the reactions and mechanistic studies for the sorption and degradation of CWAs were conducted using direct polarization and cross polarization solid-state magic-angle spinning NMR techniques. Performance toward the sorption and detoxification of HD was tested, exhibiting oxidation within minutes in a mild and selective manner to the nontoxic sulfoxide derivative followed by visible formation of iodine. The results indicate that carboxylate moieties in the matrix are important for stabilizing the pos. charged sulfonium ion intermediate and for supplying oxygen for hydrolysis in a water-deficient environment. The NaOBz/NIS composite was shown to be the most efficient in sorbing and converting the water-insoluble agent HD to its nontoxic, water-soluble sulfoxide, which could then be removed from the site with mere water, resulting in less environmental damage and quick remediation. In the experiment, the researchers used many compounds, for example, 1-Iodopyrrolidine-2,5-dione(cas: 516-12-1HPLC of Formula: 516-12-1)

Huang, Haifu’s team published research in Nanomaterials in 2019 | CAS: 516-12-1

The author of 《One-step synthesis of self-supported Ni3S2/NiS composite film on Ni foam by electrodeposition for high-performance supercapacitors》 were Huang, Haifu; Deng, Xiaoli; Yan, Liqing; Wei, Geng; Zhou, Wenzheng; Liang, Xianqing; Guo, Jin. And the article was published in Nanomaterials in 2019. SDS of cas: 516-12-1 The author mentioned the following in the article:

Herein, a facile one-step electrodeposition route was presented for preparing Ni3S2/NiS composite film on Ni foam substrate (denoted as NiSx/NF). The NiSx granular film is composed of mangy interconnected ultra-thin NiSx nanoflakes with porous structures. When applied as electrodes for supercapacitors, the ultra-thin nanoflakes can provide more active sites for redox reaction, and the interconnected porous structure has an advantage for electrolyte ions to penetrate into the inner space of active materials quickly. As expected, the obtained NiSx/NF sample exhibited high gravimetric capacitance of 1649.8 F·g-1 and areal capacitance of 2.63 F·cm-1. Furthermore, a gravimetric capacitance of 1120.1 F·g-1 can be maintained at a high c.d. of 20 mA·cm-1, suggesting a good rate capability. The influence of the different molar ratios of electrodeposition electrolyte (NiNO3 and thiourea) on the morphol. and electrochem. properties of NiSx/NF sample was investigated to provide an optimum route for one-step electrodeposition of Ni3S2/NiS composite film. The outstanding performance indicated the Ni3S2/NiS composite film on Ni foam has great potential as an electrode material for supercapacitors. In the experiment, the researchers used 1-Iodopyrrolidine-2,5-dione(cas: 516-12-1SDS of cas: 516-12-1)

Qu, Zheng-Wang’s team published research in ChemCatChem in 2020 | CAS: 516-12-1

《Mechanistic Insights for Aniline-Catalyzed Halogenation Reactions》 was published in ChemCatChem in 2020. These research results belong to Qu, Zheng-Wang; Zhu, Hui; Grimme, Stefan. Related Products of 516-12-1 The article mentions the following:

Lewis base catalyzed electrophilic aromatic halogenation using N-halosuccinimides (NsX; X=Cl, Br, I) under mild conditions has attracted much attention, but the detailed mechanism remains elusive. Using the aniline MesNH2 and anisole PhOMe as the typical base catalyst and aromatic substrate, resp., a novel mechanism is revealed by extensive DFT calculations The autogenic protonation of imine XMes=NH (via Mes=NH+ mediated dimerization of MesNH2) is crucial to initialize the electrophilic halonium X+ transfer to nucleophilic substrates. It is shown that the aniline MesNH2 and more basic imine XMes=NH may act as efficient halonium X+ and proton H+ shuttles, resp., connected by the arenium XMesNH2+. Non-coordinating MesNH3+ salts are suggested as efficient catalyst for electrophilic iodination. Without suitable stabilization of the highly basic anion Ns-, the generally accepted concept of Lewis base catalyst as simple X+ shuttle will never work efficiently due to a high thermodn. barrier. In general, autogenic or addnl. acid additives should be used for more efficient Lewis base catalyzed halogenation. In the experiment, the researchers used many compounds, for example, 1-Iodopyrrolidine-2,5-dione(cas: 516-12-1Related Products of 516-12-1)

《Postsynthetic crystalline transformation in two-dimensional perovskites via organothiol-based chemistry》 was written by Yuan, Zilong; Zhao, Liang; Pradhan, Ekadashi; Lai, Ming; Zeng, Tao; Yang, Zhenyu. Quality Control of 1-Iodopyrrolidine-2,5-dioneThis research focused ontwo dimensional perovskite crystalline transformation organothiol chem. The article conveys some information:

The first postsynthetic solution-based crystal transformation of two-dimensional metal halide perovskites (2D MHPs) through organothiol-based reactions is reported. It is well-established that the crystal formation from a solution containing predesigned metal ion and organic cation precursors produces well-defined 2D MHPs with various intercalating organic cations. However, few reports outlining the postsynthetic crystal transformation of 2D MHPs have appeared. Here, we report that, upon organothiol-based redox or condensation reactions, large organic cations in three types of 2D MHPs can interconvert under ambient conditions without damage to the layered inorganic framework. The swift and complete crystal interconversion has been confirmed using combined techniques including X-ray diffraction and 13C NMR (13C NMR) spectroscopy. Electronic structures of the MHPs were investigated using computational chem.1-Iodopyrrolidine-2,5-dione(cas: 516-12-1Quality Control of 1-Iodopyrrolidine-2,5-dione) was used in this study.

And the article was published in Nanotechnology in 2019. COA of Formula: C4H4INO2 The author mentioned the following in the article:

NiS nanoparticles modified black TiO2 hollow nanotubes (NBTNs) are successfully synthesized via surface hydrogenation and the facile solvothermal method. The unique structure with intensified surface and interface characteristics endow NBTNs with more catalytic sites, and increase charge carrier separation efficiency with an extended charge lifetime, overwhelmingly promoting its photocatalytic performance. The resultant NBTNs possess a relatively high surface area and pore size of 89 m2 g-1 and 9.8 nm, resp. The resultant NBTNs exhibit an excellent solar-driven photocatalytic hydrogen rate (3.17 mmol h-1 g-1), which is almost as high as that of Pt as cocatalyst, in which the apparent quantum yield of 5.4% (420 nm) is recorded for the NBTNs sample. Moreover, the turnover number can be up to 116 000 within 48 h and the turnover frequency is 2400 for NiS. This novel strategy could provide a better understanding of cocatalyst photocatalytic mechanisms, and a scheme simultaneously regulating the morphol. and structure of photocatalysts for promoting H2 generation.

《Hydrogen Evolution and Wastewater Treatment of Hydrangeal-like Catalyst Decorated by the NiS Nanosheet and Pd Nanoparticle》 was written by Shi, Qingdan; Zhou, Yan; Sun, Wen; Wang, Han; Li, Shenghong; Zhang, Xinyu; Wan, Junmin. COA of Formula: C4H4INO2 And the article was included in ChemistrySelect in 2020. The article conveys some information:

Multifunctional catalysts with photodegradation of organic contaminants and electrocatalytic hydrogen evolution are extremely urgent. In this work, a unique MoS2 hollow microsphere with a diameter of 1.5μm was fabricated without adding any spherical template by an improved hydrothermal process. Interestingly, the MoS2 hollow microspheres with introduction of the NiS and Pd nanoparticles greatly restrain recombination rates of electron-hole pairs, resulting in the outstanding photocatalytic activity. The RhB removal rates of the MoS2 hollow microsphere and the NPMS composites were 7 and 10 times higher than that of pure MoS2, resp., for the high concentration of macrocyclic contaminants under visible-light illumination. Furthermore, the optimal robust NPMS hybrids exhibite a lower overpotential of 100 mV (at 10 mV cm-2) and a smaller Tafel slope of 50 mV dec-1. The unique structure composite catalysts possess more exposed active sites and defects to enhance the catalytic activity for HER and removal of organic pollution.

Miao, Yongqiang’s team published research in Nano Research in 2020 | CAS: 516-12-1

《Flower-like NiCo2S4 nanosheets with high electrochemical performance for sodium-ion batteries》 was written by Miao, Yongqiang; Zhao, Xiaosen; Wang, Xin; Ma, Chenhui; Cheng, Lu; Chen, Gang; Yue, Huijuan; Wang, Lei; Zhang, Dong. Related Products of 516-12-1 And the article was included in Nano Research in 2020. The article conveys some information:

A three-dimensional flower-like NiCo2S4 formed by two-dimensional nanosheets is synthesized by a facile hydrothermal method and utilized as the anode for sodium-ion batteries. Studies have shown that materials can achieve the best performance under the ether-based electrolyte system with voltage ranging from 0.3 to 3 V, which could effectively avoid the dissolution of polysulfides and over-discharge of the material. Here, sodium storage mechanism and charge compensation behaviors of this ternary metal sulfide are comprehensively investigated by ex situ X-ray diffraction. Moreover, ex situ Raman spectra, ex situ XPS and transmission electron microscopy measurements are used to related tests for the first time. Addnl., quant. kinetic anal. unravels that sodium storage partially depends on the pseudocapacitance mechanism, resulting in good specific capacity and excellent rate performance. The initial discharge capacity is as high as 748 mAh·g-1 at a c.d. of 0.1 A·g-1 with the initial coulomb efficiency of 94%, and the capacity can still maintain at 580 mAh·g-1 with the Coulomb efficiency close to 100% after following 50 cycles. Moreover, by the long cycle test at a high c.d. of 2 A·g-1, the capacity can still reach at 376 mAh·g-1 after over 500 cycles. [graphic not available: see fulltext].
