In this work, chitosan and chitosan/montmorillonite (MMT) microspheres, containing the 5-Fluorouracil (5-FU) antitumor drug, were produced by phase inversion technique using a simple and low cost equipment developed during ...

Corrosion failures are the main cause of leakage in the industry, especially in oil. For this reason, the use of new materials with better resistance to this phenomenon has been studied. This study aimed to obtain Ni-W ...

Lanthanides accompany lighting systems since their beginnings, and there are no equivalent substitutes for the generation of light in current systems, so that such elements are already present in the future of photoluminescent ...

In this work self-assembly films were deposited on the surface of specimens of polyamide 6 (PA6). These films were obtained by the technique of layer-by-layer (LbL). It was used A positively charged hydrosoluble polyelectrolyte: ...

Clays are key components of mass for production of traditional ceramic materials because they ensure plasticity in the shaping step and mechanical strength after firing, due to the phase and microstructural transformations ...

Stents are tubular and expandable endoprostheses that can be coated with biodegradable polymeric matrices in order to create a coating that can act passively, serving as a barrier between the metal surface and the biological ...

The accumulation of residues over the years has resulted in the formation of a potential risk of environmental pollution and causes serious impacts; direct deposit in the soil of these residues can include harmful pollutants, ...

Recurrent Aphthous Stomatitis (RAS) is one of the most common pathological oral mucosal lesion, of variable size and duration, typically found in the non-keratinized oral mucosa. Topical agents are the first treatment ...

This work aims to study NiTi shape memory alloy (SMA) welded joints of thin sheets, in the austenitic and martensitic states, by the GTAW, PAW and LBW welding processes using the factorial design technique. It was verified ...

Biocomposites biopolymer / clay and biopolymer / clay / copolymer were prepared by extrusion followed injection, which assessed the levels of two kinds of clay (bentonite and vermiculite) organophilizated and two copolymers ...
