The Kinetics of Ampicillin Release from Hydroxyapatite for Bones Regeneration
International Journal of Chemical Engineering, Volume 2009, Issue 1, 2009., 2009 Semisynthetic beta‐lactam antibiotics are among the most used pharmaceuticals. Their use in veterinary and human medicine is in continuous expansion. There is a growing need for developing bioactive implants. Advantages of implantable drug delivery tools can include high release efficiency, precise dose control, low toxicity, and allow to overcome ...

Co‐combustion of coal and biomass waste in pilot‐scale for energy use
Environmental Progress &Sustainable Energy, Volume 44, Issue 3, May/June 2025.Abstract The use of biomass in co‐combustion systems using fluidized bed technology is considered a viable alternative to reduce the emission of pollutants. The herein study presents an experimental analysis to determine the technical feasibility of using run‐of‐mine (ROM) coal and its waste combined with biomass in a combustor of bubbling fluidized ...

Low Temperature Synthesis of Li2SiO3: Effect on Its Morphological and Textural Properties
Advances in Materials Science and Engineering, Volume 2008, Issue 1, 2008., 2008 Synthesis, at low temperature, of Li2SiO3 was investigated using different Li : Si molar ratios and urea, which was used as template. This new synthesis was performed in order to look for different textural and morphological properties than those obtained usually by conventional methods in this kind of ceramics. XRD and SEM analyses showed that Li2SiO3
