Anodic oxidation is a technique widely used to improve the bioactivity of Ti surface. In this study, micro-arc oxidation (MAO) was used to obtain an anodic film incorporating Ca and P ions to evaluate the effect of heat ...

Hydrogels are a fusion of solid and liquid phases which closely mimic biological tissue. As such they have enormous potential for drug delivery systems as they are biocompatible and may be tailored to specific applications. ...

Unidirectional freeze casting for polymers and ceramics has been performed extensively; however, the mechanisms involved in unidirectional freezing are not thoroughly understood and therefore, in this study, polyvinyl ...

Pyroligneous acid (PA) is a by-product of bio-oil, which is obtained by pyrolysis of the wood. This product has been tested for use in several areas, such as agriculture, as a promising green herbicide; however, there are ...

The seeds from Araucaria angustifolia—commonly named as pinhão—are important culturally, and viable regional food from Brazil. Although now considered an endangered species, methods to increase the awareness of this tree ...

There is a commercial and beneficial interest of producing yerba mate leaves into different grades of caffeine. This work uses a handheld and bench near infrared spectroscopy to compare and predict, using partial least ...

Stimuli Sensitive hydrogels have enormous potential in various applications. Various environmental variables are found in the body, such as low pH and elevated temperatures. For this reason, either pH-sensitive and/or ...

Hydrogels are three-dimensional crosslinked polymeric networks capable of imbibing substantial amounts of water or biological fluids and are widely used in biomedical applications, especially in pharmaceutical industry as ...

Porous TiO2 coatings were produced on commercially pure Ti substrates by micro-arc oxidation (MAO) in 1.0 M H2SO4 electrolyte for different anodizing times. Their mechanical properties were assessed by means of instrumented ...

The field of biomedical applications for hydrogels requires the development of nanostructures with specific controlled diameter and mechanical properties. Nanofibers are ideally candidates for these advanced requirements, ...
