In this work, morphologically different TiO2 nanocrystals were synthesized through the OPM method with the objective of performing a comparative study related to photoactivity. Morphological characterization was performed ...

In this work classical molecular dynamics was used to study the pure ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate, [BMIM]+[BF4]-, and some solutions based in it. The OPLS-AA force field and CHelpG derived ...

Nanocomposites were developed based on polyacrylamide hydrogels (PAAm) and methylcellulose (MC) reinforced with montmorillonite (MMT), undergoing the materials to subsequent hydrolysis process and evaluating their loading ...

Manganese dioxide was synthesized by a microwave-hydrothermal method using alternative, unprecedented and completely soluble reagents. For such, potassium permanganate and acetone were dissolved in different proportions ...

In this work the anodic film growth on metals has been studied, under voltammetric conditions by simulation. It was supposed that: a) the films are ultrathin, i.e., the concentration gradient contributions for the ionic ...

The current market demands make with what Brazilian agribusiness search improvements in processes and new materials to reduce waste, pollution and biological contamination. Mainly materials that more are easily degraded ...

This work presents a study of the 1020 and 1040 carbon steel corrosion in aqueous solution containing dissolved H2S in order to investigate the effect of H2Saq and HSaq species. Some different electrolytes were used: acetic ...

The microwave-assisted hydrothermal method was implemented in the synthesis of alkaline earth titanates under ABO3 stoichiometric known as perovskites, being efficient and innovative. For that, OH- groups played an important ...

Natural rubber (NR) is a basic raw material used in the manufacture of a wide range of rubber goods. Usually both quality and productivity levels of Brazilian NR are lower than the imported NR. This is due to a lack of ...
