Sonochemical Synthesis of Magnetite/Poly(lactic acid) Nanocomposites.

Nanocomposites based on poly(lactic acid) (PLA) and magnetite nanoparticles (MNP-FeO) show promise for applications in biomedical treatments. One key challenge is to improve the stabilization and dispersion of MNP-FeO. To address this, we synthesized MNP-FeO/PLA nanocomposites using ultrasound mediation and a single iron(II) precursor, eliminating the need for surfactants or organic solvents, and conducted the process under ambient conditions.

Polymers Based on PLA from Synthesis Using D,L-Lactic Acid (or Racemic Lactide) and Some Biomedical Applications: A Short Review.

Poly(lactic acid) (PLA) is an important polymer that is based on renewable biomass resources. Because of environmental issues, more renewable sources for polymers synthesis have been sought for industrial purposes. In this sense, cheaper monomers should be used to facilitate better utilization of less valuable chemicals and therefore granting more sustainable processes.

Cerium-zirconium mixed oxide nanostructures for diesel soot oxidation: synthesis and effect of structure.

Nanostructured materials have been used in several branches of science and technology. Particulate matter is one of the major air pollution concerns. In this work, nanorods and nanoparticles of CeZrO (CZ) mixed oxides were prepared by different routes, and the use of an organic template was evaluated in diesel soot oxidation.

Liquid phase calorimetry and adsorption analyses of zeolite beta acidity.

Zeolite beta acidity, activated at 550 degrees C, was characterized by calorimetric and adsorption studies of pyridine in cyclohexane (Cal-Ad). Two different acid sites were found: n(1) = 0.1612 mmol g(-1) with DeltaH(1) = -83.
