Author is Das, Debasish; Hashmi, Sabiha; Sengupta, Arijit; Kannan, S.; Kaushik, C. P..

The manuscript deals with efficient separation of hexavalent UO2+2 and tetravalent Th4+ from aqueous acidic waste solution in green way using ionic liquid with novel picolinamide (L I) and N-oxo picolinamide (L II) based ligands. A comparative evaluation was carried out to understand the extraction mechanism, kinetics, thermodn., speciation, radiolytic stability and stripping behavior of UO2+2 and Th4+ in ionic liquid vis-a-vis mol. diluent. The investigation demonstrates the predominance of cation exchange mechanism in ionic liquid and solvation mechanism in n-dodecane based systems. The slower extraction kinetics in ionic liquid was attributed to the viscosity effect. The extractive mass transfer processes were found to be spontaneous, endothermic and entropically driven in nature. The picolinamide and N-oxo picolinamide ligands were found to form inner-sphere complexes in ionic liquid as well as n-dodecane. The CO2-3 was more effective aqueous phase complexing agent to back extract UO2+2, while C2O2-4 exhibited the same for Th4+.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called α-Hydroxy-Tetrazoles as Latent Ethynyl Moieties: A Mechanistic Investigation, published in 2019, which mentions a compound: 57399-11-8, Name is 4-Chloro-4′-ethynyl-1,1′-biphenyl, Molecular C14H9Cl, Application of 57399-11-8.

This article focuses on the dehydration of α-hydroxy-tetrazoles, leading to tetraazafulvenes and then to vinylic carbenes that rearrange into ethynyl moieties through the Fritsch-Buttenberg-Wiechell rearrangement. Each step of this sequence was scrutinized, either by examination of the substrate and/or dehydrating agent scope, or through AM1 calculations, to understand the limiting step of this process. This underrated transformation appears to be a viable alternative to existing methods used for transforming aldehydes into alkynes.

The article 《Alkyl Chain Tuning of Small Molecule Acceptors for Efficient Organic Solar Cells》 in relation to this compound, is published in Joule. Let’s take a look at the latest research on this compound (cas:693-67-4).

The field of organic solar cells has seen rapid developments after the report of a high-efficiency (15.7%) small mol. acceptor (SMA) named Y6. In this paper, we design and synthesize a family of SMAs with an aromatic backbone identical to that of Y6 but with different alkyl chains to investigate the influence of alkyl chains on the properties and performance of the SMAs. First, we show that it is beneficial to use branched alkyl chains on the nitrogen atoms of the pyrrole motif of the Y6. In addition, the branching position of the alkyl chains also has a major influence on material and device properties. The SMA with 3rd-position branched alkyl chains (named N3) exhibits optimal solubility and electronic and morphol. properties, thus yielding the best performance. Further device optimization using a ternary strategy allows us to achieve a high efficiency of 16.74% (and a certified efficiency of 16.42%).

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Multistate luminescence, absorption and MCD studies of the relative energies of d → d, d → π*, and n,π → π* transitions for the cis and trans isomers of dichlorobis(pyridine)platinum(II), published in 1983-02-16, which mentions a compound: 15227-42-6, mainly applied to UV luminescence platinum chloride pyridine; magnetic CD platinum chloride pyridine, Computed Properties of C10H10Cl2N2Pt.

Luminescence, absorption, and magnetic CD (MCD) experiments are reported for cis- and trans-dichlorobis(pyridine)platinum(II). For the trans isomer, an anal. of the temperature dependence of the lifetimes and luminescence intensities indicates that emission at 605 nm is from 2 excited π* states separated by 240 cm-1. For the cis isomer, time-resolved spectroscopy allowed observation of 2 emission bands at 600 and 700 nm, which were assigned from their lifetimes to π* → d and d → d transitions, resp. Further, temperature dependent lifetime studies show that the 600-nm band (π* → d) is from 2 electronic states separated by 200 cm-1. The absorption spectra of both isomers were measured at room and low temperatures in solution, in glasses, and in KCl pellets. From a comparison with the pyridine and Pt(NH3)2Cl2 absorption and MCD spectra and MO calculations, the observed absorption bands for Pt(py)2Cl2 are assigned as d → d, d → π*, and n, π → π* transitions. For the cis isomer the lowest unoccupied mol. orbital is a d metal orbital.

A series of novel N-(cinnamoyl)-N’-(substituted)acryloyl hydrazide derivatives containing pyridinium moieties I•X- [n = 4-11; R = Ph, 4-FC6H4, 2-thienyl, etc.; X = Br, I] were designed, and the anti-Xoo activity was determined The bioassay results showed that compound I•Br- [n = 10; R = Ph; X = Br] had excellent anti-Xoo activity (EC50 = 0.99 mg L-1) in vitro and distinct curative activity (63.2% at 200 mg L-1) in vivo. Further studies revealed that these designed compounds were XooFtsZ inhibitors, validating by the reduced GTPase activity of recombinant XooFtsZ, the non-filamentous XooFtsZ assembly observed in the TEM images, and the prolonged Xoo cells from the fluorescence patterns. Computational docking studies showed that compound I•Br- [n = 10; R = Ph; X = Br] had strong interactions with ASN34, GLN193, and GLN197 residues located in the α helix regions of XooFtsZ. The present study demonstrated the developed FtsZ inhibitors could serve as agents to control Xoo-induced infections.
