Lithium-ion batteries (LIBs) are widely used everywhere today, and their recycling is very important. This paper addresses the recovery of metals from NMC111 (LiNi1/3Mn1/3Co1/3O2) cathodic materials by leaching followed antisolvent precipitation. Ultrasound-assisted material was performed in 1.5 mol L−1 citric acid at 50 °C a solid-to-liquid ratio 20 g/L. Nickel(II), manganese(II) cobalt(II) we...

Development of more effective and less toxic antifungal agents is required for the treatment of dermatophytosis. Plants and their extraction preparations have been used as medicines against infectious diseases. In this research, the lemon grass [Cymbopogon citrates DC.) Stapf.], lantana (Lantana camara L.), nerium (Nerium oleander L.), basil (Ocimum basilicum L.) and olive leaves (Olea europaea...

A simple and rapid in vitro chemical solubility test applicable to industrial uranium trioxide (UO3) was developed together with two in vitro cellular tests using rat alveolar macrophages maintained either in gas phase or in alginate beads at 37 degrees C. Industrial UO3 was characterized by particle size, X-ray, and IR spectra, and chemical transformation (e.g., aging and hydration of the dust...

Background: A very strict control of urinary pH is recommended to maintain it between 5.5 and 6.2, preventing formation or recurrence crystals. Kidney stones are a common problem, with high rate recurrence, not altered by the success surgery. Medical treatment prevents recurrence. Potassium Citrate inhibits crystallization calcium salts. It influences calculogenesis increasing citrates alkalini...

Highly water-soluble lanthanum and cerium citrates or malates with ethylenediaminetetraacetate (NH(4))(8)[Ln(2)(Hcit)(2)(EDTA)(2)]·9H(2)O [Ln = La, 1; Ce, 2], K(8)[La(2)(Hcit)(2)(EDTA)(2)]·16H(2)O (3) and K(6)[Ln(2)(Hmal)(2)(EDTA)(2)]·14H(2)O [Ln = La, 4; Ce, 5] (H(4)cit = citric acid, H(3)mal = malic acid, and H(4)EDTA = ethylenediaminetetracetic acid) were prepared from the reactions of lanth...
