The objectives of this study were to evaluate the effects of power ultrasound (nominal intensity 600 W·cm−2 for 10 min) and the addition of potassium chloride (KCl) on the physicochemical properties and sensorial acceptance ...

Burst release of ions from copper-based intrauterine devices (IUD) occurs during the first day after the insertion in uterus and may induce side effects in the users. In the present work, we investigate the mechanism of ...

Partially biodegradable acrylic composites containing poly(methyl methacrylate)-poly(ε-caprolactone) (PMMA/PCL) systems were prepared by mixing the corresponding PMMA/PCL beads (89:11, 86:14, 83:17, and 77:23 weight ratio) ...

Corrosion of metals in implanted biomaterials lifetime is expected to occur. Nowadays, medical implants have good biocompatibility, present proper mechanical properties, and promote tissue regeneration; nevertheless, ...

Pre-salt layer oil commonly presents a paraffinic composition, resulting on its gellification for low temperatures. With production stops in mind, the development of a tool to evaluate pressure and volumetric flow during ...

The aim of this study was to combine high hydrostatic pressure (HHP) and SFE-CO2 to extract bioactive compounds with antioxidant capacity (phenolics and β-carotene) from Cape gooseberry (Physalis peruviana L.) pulp. Extracts ...

In this study, we proposed the use of the biopolymer alginate to produce membranes with diclofenac sodium incorporated as model-drug aiming at wound dressing application with drug delivery. The membranes were prepared by ...

The mechanisms which controls the fixation and/or release of P in sediment of an extremely acidic lake (pH = 2.0 to 3.0) and its response to the influence of eutrophic urban waste water were investigated. The results, in ...
