IN THE CATION OF THE TITLE COMPOUND [SYSTEMATIC NAME: 3-(9H-carbazol-4-yl-oxy)-2-hydr-oxy-N-[2-(2-methoxy-phen-oxy)eth-yl]propan-1-aminium dihydrogen phosphate hemihydrate], C(24)H(27)N(2)O(4) (+)·H(2)PO(4) (-)·0.5H(2)O, the mean planes of the tricyclic ring system and the benzene ring form a dihedral angle of 87.2 (2)°. In the crystal structure, the solvent water mol-ecule is situated on a twofold rotation axis linking two cations via O-H⋯O and N-H⋯O hydrogen bonds. The anions contribute to the formation O-H⋯O and N-H⋯O hydrogen bonds between the anions and cations, which consolidate the crystal packing.

Reverse flotation separation of muscovite from apatite using a dodecylpyridinium chloride (DPDC) ionic liquid as the collector was studied in this work. The microflotation results depicted that DPDC had a strong collecting for muscovite but had a slight collecting for apatite when using phosphoric acid as a depressant for apatite in a weakly acidic pH value pulp, artificial mixture mineral flotation showed that reverse flotation separation of muscovite from apatite can be effectively achieved in the reagent scheme of phosphoric acid/DPDC, and DPDC had a better separation performance in the muscovite/apatite system than DDA. The adsorption measurements indicated that the adsorption amount of DPDC on the apatite surface was less than that of DPDC on the muscovite surface, and the zeta potential results confirmed that a strong interaction occurred between DPDC and the muscovite surface, while an extremely weak interaction occurred between DPDC and the apatite surface in the presence of phosphoric acid at pH ∼ 5.

Sodium reabsorption is tightly coupled to calcium reabsorption in the proximal tubule via the action of the Na/H exchanger isoform 3 (NHE3). Poulsen et al. provide evidence of reduced proximal calcium reabsorption in kidney tubule-specific NHE3-deficient mice that is compensated distally, unaltered phosphate homeostasis, and NHE3 involvement in the hypocalciuric effect of thiazides.

Phosphorus (P)-doping H-ZSM-5 zeolites, which is crucial for industrial applications, aim to adjust both acidity and framework stability while optimizing product distribution in heterogeneous catalysis. Nonetheless, current phosphating methods often suffer from inadequate phosphorus dispersion and unclear interfacial interactions with framework aluminum (Al). In this work, P-doping ZSM-5 zeolites were successfully one-step prepared by using tributylphosphine served as an organophosphorus precursor, assisting by density functional theory calculations.

Electrolyte engineering has emerged as an effective strategy for stabilizing Zn-metal anodes. However, a single solute or solvent additive is far from sufficient to meet the requirements for electrolyte cycling stability. Here, we report a new-type high-entropy electrolyte composed of equal molar amounts of Zn(OTf)2 and LiOTf, along with equal volumes of H2O, triethyl phosphate, and dimethyl sulfoxide, which enhances electrolyte stability by increasing solvation entropy.

Materials And Methods: A total of 25 HAP disks was randomly divided into five groups (n = 5): baseline, AWSLs, deionized water (DW), SDF-KI or F-varnish. After AWSLs were developed, the specimen was treated with either deionized water, SDF-KI or F-varnish.
