Lithium intercalation and deintercalation of thermally decomposed LiAl₂-layered double hydroxides was written by Lee, Yongju;Jung, Duk-Young. And the article was included in Applied Clay Science in 2022.Computed Properties of ClLi The following contents are mentioned in the article:

Lithium aluminum layered double hydroxide (LiAl₂-LDH) nanocrystals on aluminum metal substrates were synthesized to adsorb lithium in aqueous solutions and utilized to collect lithium in aqueous media. LiAl₂-LDH is transformed at 300°C into a mixture of LiCl and Li-Al-O-OH; dissolved lithium in deionized water at 25°C reached 85% compared to the intercalated lithium content. Amorphous Li-Al-O-OH residues on the aluminum metal substrate were capable of adsorbing lithium ions back to the lithium rich LiAl₂-LDH phase. Thermal treatment followed by addnl. lithium intercalation suggested a topotactic reaction of lithium ions between amorphous Li-Al-O-OH and LiAl₂-LDH. We also proposed a facile recycling method of lithium ions by peeling off the Li-Al-O-OH layer to save the aluminum metal substrate. This study involved multiple reactions and reactants, such as Lithium chloride (cas: 7447-41-8Computed Properties of ClLi).

And the article was included in Angewandte Chemie, International Edition in 2017.COA of Formula: C6H12BrCl The following contents are mentioned in the article:

A membrane-intercalating conjugated oligoelectrolyte (COE), PTTP, was designed and synthesized with the goal of providing red-shifted absorption spectra relative to previously synthesized COE analogs. Specifically, electron-rich and electron-poor subunits were introduced in the conjugated backbone to modulate the band gap. PTTP exhibits maxima of absorption at 507 nm and of emission at 725 nm. PTTP can also efficiently function to generate singlet oxygen in situ (Φ_Δ ≈20 %) and has appropriate topol. and dimensions to interact with lipid membranes. The resulting rapid membrane insertion and sensitizing ability provide PTTP with a highly efficient antibacterial capability under a low light dose (0.6 J cm^-2) toward Gram-neg. bacteria E. coli, making it a remarkably efficient optically mediated antimicrobial agent.

Porous ZnFe₂O₄ sphere decorated with highly dispersed Pd nanoparticles as an efficient catalyst for the selective hydrogenation of styrene was written by Shen, Congcong;Yang, Yinhui;Wu, Xiaolu;Liu, Yanan. And the article was included in Materials Letters in 2022.HPLC of Formula: 13820-53-6 The following contents are mentioned in the article:

The catalytic hydrogenation of olefins is common and important in the chem. industry. In this work, the uniform Pd nanoparticles (-2 nm) are anchored on the porous ZnFe₂O₄ particles to develop the Pd/ZnFe₂O₄ nanocomposites. We applied the Pd/ZnFe₂O₄ hybrids into a model reaction, namely the hydrogenation of styrene. The styrene can be completely restored into ethylbenzene over Pd/ZnFe₂O₄ within 80 min. Meanwhile, no byproducts or derivatives are formed during the whole photocatalytic process. Above photocatalytic performance is ascribed to the synergistic interaction of porous ZnFe₂O₄ and highly dispersive Pd NPs. In addition, the kinetics study with an R-square value of more than 0.99 showed that the hydrogenation of styrene matches the zero-order kinetics model well.

Aryne [3 + 2] cycloaddition with N-sulfonylpyridinium imides and in situ generated N-sulfonylisoquinolinium imides: a potential route to pyrido[1,2-b]indazoles and indazolo[3,2-a]isoquinolines was written by Zhao, Jingjing;Li, Pan;Wu, Chunrui;Chen, Hongli;Ai, Wenying;Sun, Renhong;Ren, Hailong;Larock, Richard C.;Shi, Feng. And the article was included in Organic & Biomolecular Chemistry in 2012.Reference of 1186603-47-3 The following contents are mentioned in the article:

The aryne [3 + 2] cycloaddition process with pyridinium imides breaks the aromaticity of the pyridine ring. By equipping the imide nitrogen with a sulfonyl group, the intermediate readily eliminates a sulfinate anion to restore the aromaticity, leading to the formation of pyrido[1,2-b]indazoles. E.g., [3 + 2] cycloaddition of the aryne formed from 3-methoxy-2-trimethylsilylphenyl triflate with N-tosylpyridinium imide gave 77% pyrido[1,2-b]indazole (I). The scope and limitation of this reaction are discussed. As an extension of this chem., N-tosylisoquinolinium imides, generated in situ from N’-(2-alkynylbenzylidene)tosylhydrazides via an AgOTf-catalyzed 6-endo-dig electrophilic cyclization, readily undergo aryne [3 + 2] cycloaddition to afford indazolo[3,2-a]isoquinolines in the same pot, offering a highly efficient route to these potential anticancer agents. This study involved multiple reactions and reactants, such as 5-Chloro-2-(phenylethynyl)benzaldehyde (cas: 1186603-47-3Reference of 1186603-47-3).
