《Porous honeycomb-like NiSe2/red phosphorus heteroarchitectures for photocatalytic hydrogen production》 was written by Jia, Jia; Bai, Xue; Zhang, Qiqi; Hu, Xiaoyun; Liu, Enzhou; Fan, Jun. Reference of 1-Iodopyrrolidine-2,5-dione And the article was included in Nanoscale in 2020. The article conveys some information:

Heterojunction construction of semiconductors with a matched bandgap can not only help promote visible light absorption but also restrain photoexcited charge carrier recombination and optimize the separation efficiency. Herein, a novel porous honeycomb-like NiSe2/RP heterostructure is reported for the first time by in situ deposition of NiSe2 nanoparticles on the surface of red phosphorus (RP). The optimized binary NiSe2/RP composite showed superior photocatalytic H2 evolution activity (1968.8μmol g-1 h-1) from Na2S/Na2SO3 solution under solar light illumination, which was 2.32, 1.90, 1.59 and 1.21 times that of pristine RP, NiSe2, 5.3% FeS/RP and 8.1% NiS/RP, resp. Such a prominently improved photocatalytic performance could be ascribed to extended light absorption ability, massive reactive centers and lower interfacial transfer resistance, together with expedited charge separation, which arose from a successive two-electron/two-step reduction route. This study provides illuminating insights for the rational exploration and fabrication of potential photocatalytic systems with 0D/3D integrated nanoarchitecture and a multi-step electron transfer process for efficiently realizing solar energy capture and conversion.

The title of the article was 《Flexible and Conductive Polymer Threads for Efficient Fiber-Shaped Supercapacitors via Vapor Copolymerization》.Formula: C4H4INO2 The author mentioned the following in the article:

Flexible fiber electrodes are critical for high-performance fiber and wearable electronics. In this work, we presented a highly conductive all-polymer fiber electrode by vapor copolymerization of 2,5-dibromo-3,4-vinyldioxythiophene (DBEDOT) and 2,5-diiodo-3,4-vinyldioxythiophene (DIEDOT) monomers on commonly used polyester threads (PETs) at a temperature as low as 80°C. The poly(3,4-ethylenedioxythiophene) (PEDOT)-coated PET threads maintain excellent flexibility and show conductivity of 7.93 S cm-1, nearly four times higher than that reported previously via homopolymerization of DBEDOT monomer. A MnO2 active layer was embedded into the PEDOT double layers, and the flexible fiber composite electrode showed a high linear specific capacitance of 157 mF cm-1 and improved stability, retaining 86.5% capacitance after 5000 cycles. Fiber-shaped solid-state supercapacitors (FSSCs) based on the composite electrodes were assembled, and they displayed superior electrochem. performance.

Sun, Jifu; Li, Weixu; Hou, Yuqi; Zhang, Xue; Gao, Zhongzheng; Wang, Bo; Zhao, Jianzhang published an article in 2021. The article was titled 《a-PET and Weakened Triplet-Triplet Annihilation Self-Quenching Effects in Benzo-21-Crown-7-Functionalized Diiodo-BODIPY》, and you may find the article in ACS Omega.Safety of 1-Iodopyrrolidine-2,5-dione The information in the text is summarized as follows:

Weakening the triplet-triplet annihilation (TTA) self-quenching effect induced by sensitizers remains a tremendous challenge due to the very few investigations carried out on them. Herein, benzo-21-crown-7 (B21C7)-functionalized 2,6-diiodo-1,3,5,7-tetramethyl-8-phenyl-4,4-difluoroboradiazaindacene (DIBDP) was synthesized to investigate the influences of huge bulks and electron-rich cavities of B21C7 moieties on the fluorescence emission and triplet-state lifetimes of DIBDP moieties. D. functional theory (DFT)/time-dependent DFT (TDDFT) computable results preliminarily predicted that B21C7 moieties had influences on the fluorescence emissions of DIBDP moieties but not on their localization of triplet states of B21C7-functionalized DIBDP (B21C7-DIBDP). The UV-vis absorption spectra, fluorescence emission spectra, and cyclic voltammograms verified that there was an electron-transfer process from the B21C7 moiety to the DIBDP moiety in B21C7-DIBDP. However, the calculated results of ΔGCS and ECS values and nanosecond time-resolved transient absorption spectra demonstrated that the electron-transfer process from the B21C7 moiety to the DIBDP moiety in B21C7-DIBDP had direct influences on the fluorescence emission of DIBDP moieties but not on the triplet states of DIBDP moieties. The exptl. values of triplet-state lifetimes of B21C7-DIBDP were obviously longer than those of DIBDP at a high concentration (1.0 x 10-5 M); however, the fitted values of intrinsic triplet-state lifetimes of B21C7-DIBDP were slightly greater than those of DIBDP in the same solvent. These results demonstrated that the steric hindrance of B21C7 moieties could weaken the TTA self-quenching effect of DIBDP moieties at a high concentration and the a-PET effect induced a proportion of the produced singlet states of DIBDP moieties and could not emit fluorescence in the form of radiation transition but they could be transformed into triplet states through intersystem crossing (ISC) processes due to the iodine atoms in the DIBDP moiety. The stronger a-PET effects in polar solvents induced smaller fluorescence quantum yields so that more singlet states of DIBDP moieties were transformed into triplet states to weaken the TTA self-quenching effects.

The title of the article was 《Tailoring MSx Quantum Dots (M = Co, Ni, Cu, Zn) for Advanced Energy Storage Materials with Strong Interfacial Engineering》.Related Products of 516-12-1 The author mentioned the following in the article:

Metal sulfides, as vital members of electrodes materials, still suffer from serious volume expansion and polysulfides shuttling. Herein, through inexpensive and high efficiency chem.-bonding/hydrophobic-association methods, a series of metal-sulfides quantum dots (QDs) with large-scale synthesis (≈100 g) is successfully prepared, further forming low-dimensional composites with high redox activity. For the derived electrodes samples, with the increasing of outer electron numbers (Co2+/Ni2+/Cu2+/Zn2+), interfacial coupling is significantly modified. Among them, nanoscale ZnS@double carbon with rich interfacial Zn-O/S-C bonds displays remarkable electrochem. activity, with the capacity of ≈1000 mAh g-1 after 100 loops. Through tailoring double carbons and interfacial merits, in situ sulfur formation is stabilized, and the cycling stability of Zn-based samples can increase up to 4000 cycles. Even at 5.0 A g-1 after 1500 cycles, the full-cells capacity can reach up to ≈380 mAh g-1. Supported by detailed kinetic anal. and ex situ technologies, the enhanced interfacial capacitances and ions moving are confirmed for the improved electrochem. properties. Given this, the work is expected to boost future developments of mineral processing, and QDs preparation, while providing effective strategies for advanced electrode materials.1-Iodopyrrolidine-2,5-dione(cas: 516-12-1Related Products of 516-12-1) was used in this study.

Developing robust water splitting photocatalyst remains a pivot challenge for solar-to-fuel conversion. Herein, two-dimensional (2D) Janus bilayer heterostructures are reported by sulfur-vacancy-confined-in ZnIn2S4 (Vs-ZnIn2S4) and WO3 nanosheets as an all-solid-state Z-scheme prototype. First-principle calculations and exptl. observations clearly confirm the spontaneous formation of this redox-mediator-free Z-scheme van der Waals heterostructure at at. level, not only facilitating the space separation of photoexcited carriers with high charge d., enhancing charge dynamics and optimizing charge lifetime, but also accumulating electrons in conduction band of Vs-ZnIn2S4 and holes in valence band of WO3 by internal elec. field through W-S bonds. After integrated by NiS quantum dots, novel 2D/2D NiS/Vs-ZnIn2S4/WO3 heterostructures with high stability exhibited an outstanding visible-light hydrogen evolution rate of 11.09 mmol g-1 h-1 and an apparent quantum efficiency about 72% at 420 nm, the highest value so far reported among the family of ZnIn2S4 photocatalysts. This work not only presents novel Janus heterostructures but also paves the at.-level structural and interfacial design and the construction of 2D Janus bilayer Z-scheme heterojunctions for solar energy conversion applications.

SDS of cas: 516-12-1 And the article was included in Nanoscale in 2020. The article conveys some information:

Hierarchical nanostructures with outstanding electrochem. properties and mech. stability are ideal for constructing flexible hybrid supercapacitors. Herein, hierarchically hollow NiCo2S4@NiS nanostructures were designed and synthesized by sulfurizing the hierarchical NiCo double hydroxides (DHs) coated with nickel hydroxide nanostructures on carbon fabrics (NiCo-DHs@Ni(OH)2/CF), which trigger excellent electrochem. performances. The NiCo2S4@NiS/CF exhibits a high specific capacity of 1314.0 C g-1 at a c.d. of 1 A g-1, and maintains the rate performance at about 79.2% of the initial capacity at 30 A g-1. The hybrid supercapacitors of NiCo2S4@NiS//AC display a high energy d. of 62.4 W h kg-1 at a power d. of 800 W kg-1 with a remarkable cycling stability (96.2% of initial capacitance after 5000 cycles) and robust mech. flexibility (no obvious decay of specific capacitance during various deformations).

Rana, Rahul; Chang, Qing; Bassan, Jay; Chow, Sue; Hedley, David; Nitz, Mark published their research in ChemBioChem in 2021. The article was titled 《An Iodinated DAPI-Based Reagent for Mass Cytometry》.Recommanded Product: 516-12-1 The article contains the following contents:

Multiparametric single-cell anal. has seen dramatic improvements with the introduction of mass cytometry (MC) and imaging mass cytometry (IMC). These technologies expanded the number of biomarkers that can be identified simultaneously by using heavy-isotope-tagged antibody reagents. Small-mol. probes bearing heavy isotopes are emerging as addnl. useful functional reporters of cellular features. Realizing this, we explored the iodination of DAPI to produce a heavy-atom-substituted derivative of the commonly used fluorescent DNA stain. Although exhibiting a drastically reduced fluorescence emission profile, I-DAPI retains strong binding affinity for DNA. I-DAPI was used to detect cellular DNA in MC and IMC assays with comparable efficiency to known Ir-containing DNA intercalators. This work suggests repurposing well-known colorimetric stains through simple reactions could be an effective strategy to develop new, functional MC and IMC reagents.

Synthesis of a pentasaccharide repeating unit corresponding to the cell of wall O-antigen Shigella boydii type 18 has been achieved by sequential as well as iterative glycosylation in one-pot. Use of p-methoxybenzyl group (PMB) as an in situ removable protecting group allowed obtaining the desired pentasaccharide derivative in a generalized glycosylation condition and in one-pot condition. Synthesis of a beta-L-rhamnosidic linkage present in the mol. has been successfully achieved using L-rhamnosyl thioglycoside donor having a picoloyl group at remote C-3 position influencing beta selectivity in the glycosylation. A combination of N-iodosuccinimide (NIS) and perchloric acid supported over silica (HClO4-SiO2) has been used as thiophilic glycosylation promoter in all glycosylation reactions.

《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)
