Radioactive sources are widely used in modern society but are not widely known by the lay public. Unfortunately, these materials can be stolen and can cause serious problems to society. Assessing this kind of event is only possible if nuclear chemistry and radiochemistry concepts are recognized.

The study investigates thermoplastic starch (TPS) biocomposites with ucuuba fibers, focusing on the effect of buriti pulp oil. This oil improved the matrix, decreasing hydrophilicity and slightly increasing strength, while rheological and scanning electron microscopy (SEM) analyses confirmed better plasticization and enhanced thermal stability.

In the research, a bio adsorbent was produced as an alternative to textile wastewater treatment and could act as a tool for recycling dyes and saving water. This process would reduce the costs of dyeing fabrics by obtaining a new "ecological dye" for subsequent tanning.

A composite photocatalyst, xTCN, was synthesized using a simple one-step hydrothermal method, with H2O2 as the oxidant. This approach effectively reduced the bandgap energy and minimized the recombination of photogenerated carriers. The bandgap structure of g-C3N4 was modified by the incorporation of an O atom, improving the separation efficiency of the photogenerated electrons and holes.
