N-N(+) Bond-Forming Intramolecular Cyclization of O-Tosyloxy β-Aminopropioamidoximes and Ion Exchange Reaction for the Synthesis of 2-Aminospiropyrazolilammonium Chlorides and Hexafluorophosphates.
Publication Type: Academic Journal
Source(s): International Journal of Molecular Sciences. Jul2023, Vol. 24 Issue 14, p11315. 16p.
Abstract: Our research area is related to the spiropyrazolinium-containingcompounds, which are insufficiently studied compared with pyrazoline-containing compounds. Nitrogen-containing azoniaspiromolecules have also been well studied. In drug design and other ar...
Inhibition Roles of Calcium in Cadmium Uptake and Translocation in Rice: A Review.
Publication Type: Academic Journal
Source(s): International Journal of Molecular Sciences. Jul2023, Vol. 24 Issue 14, p11587. 17p.
Abstract: Cadmium (Cd) contamination in rice grains is posing a significant threat to global food security. To restrict the transport of Cd in the soil-rice system, an efficient way is to use the ionomics strategy. Since calcium (Ca) and Cd have similar ionic ra...
Electrospun Sandwich-like Structure of PVDF-HFP/Cellulose/PVDF-HFP Membrane for Lithium-Ion Batteries.
Publication Type: Academic Journal
Source(s): Molecules. Jul2023, Vol. 28 Issue 13, p4998. 15p.
Abstract: Cellulose membranes have eco-friendly, renewable, and cost-effective features, but they lack satisfactory cycle stability as a sustainable separator for batteries. In this study, a two-step method was employed to prepare a sandwich-like composite membr...
Phosphate-Induced Reaction to Prepare Coal-Based P-Doped Hard Carbon with a Hierarchical Porous Structure for Improved Sodium-Ion Storage.
Publication Type: Academic Journal
Source(s): Molecules. Jul2023, Vol. 28 Issue 13, p4921. 13p.
Abstract: The use of coal as a precursor for producing hard carbon is favored due to its abundance, low cost, and high carbon yield. To further optimize the sodium storage performance of hard carbon, the introduction of heteroatoms has been shown to be an effect...
Influence of Ion Exchange Process Parameters on Broadband Differential Interference.
Publication Type: Academic Journal
Source(s): Sensors (14248220). Jul2023, Vol. 23 Issue 13, p6092. 12p.
Abstract: The paper presents theoretical analyses and experimental investigations of broadband differential interference in planar gradient waveguides made via K+-Na+ ion exchange in BK-7 glass. This technology, due to its large polarimetric dispersion, is espec...
Ion Exchange MIEX ® GOLD Resin as a Promising Sorbent for the Removal of PFAS Compounds.
Publication Type: Academic Journal
Source(s): Applied Sciences (2076-3417). May2023, Vol. 13 Issue 10, p6263. 13p.
Abstract: Per- and polyfluoroalkyl substances (PFASs) are synthetic compounds, which have been widely produced, used, and recently identified as extremely toxic chemicals, and are responsible for serious environmental and human health risks. In this study, the r...
Substantial Copper (Cu 2+) Uptake by Metakaolin-Based Geopolymer and Its Resistance to Acid Leaching and Ion Exchange.
Publication Type: Academic Journal
Source(s): Polymers (20734360). Apr2023, Vol. 15 Issue 8, p1971. 15p.
Abstract: Geopolymers are inorganic, chemically resistant aluminosilicate-based binding agents, which remove hazardous metal ions from exposed aqueous media. However, the removal efficiency of a given metal ion and the potential ion remobilization have to be ass...
