In this study, spinel ferrite nanoparticles CoFe2-xLaxO4 (x = 0, 0.025, and 0.05) were successfully synthesized via a simple co-precipitation method using a 5% NaOH solution as a precipitating agent. The physicochemical properties of the materials, annealed at 850 °C for one hour, were characterized using powder X-ray diffraction (PXRD), energy-dispersive X-ray spectroscopy (EDX), transmission electron microscopy (TEM), and vibrating-sample magnetometry (VSM) at room temperature.

In everyday life, nature has given us countless useful medicinal plants. Among the common plants in Vietnam, the custard apple (Annona squamosa L.) has not been mainly used as a fruit but also traditionally as a medicine. However,studies on morphological characteristics remain limited in Vietnam as well as around the world. Determine the morphological and microscopic characteristics, and physicochemical features of A. squamosa leaves.

In this study, a computational investigation of the physicochemical properties of hypericin and pseudohypericin revealed drug-like characteristics. Pharmacokinetic predictions indicated that hypericin and pseudohypericin are non-toxic to the central nervous system, hepatic system, and cardiac system. Molecular docking results indicated a strong binding affinity of hypericin/pseudohypericin with MPXV thymidylate kinase. As a result, these compounds are being considered as potential Mpox control candidates.

Lithium (Li) is the lightest metal, has unique physicochemical properties and is the main component of lithium-ion batteries. Rechargeable lithium-ion batteries play a very important role in maximizing the performance of electric devices and vehicles. It is predicted that the metal and mineral demand for lithium-ion batteries will increase 56 times by 2050. In order to meet the increasing demand, in addition to known methods, lithium recovery from geothermal waters has become a very popular research subject.
