Hyaluronic acid is a biopolymer found in many organisms, which has several biomedical applications, like viscosupplementation and aesthetic procedures. Such applications are associated with its rheological properties, that ...

The steel industry is responsible for generating pollutants that need to be treated before being released into the atmosphere, various gases such as ammonia, benzene, carbon monoxide, sulfur dioxide and particulate matter. ...

Life cycle assessment is an environmental, economic, and social evaluation technique focused on understanding and quantifying the impacts related to a particular product, good, or service. This assessment considers all ...

Catalytic hydrogenolysis of glycerol is one of the possible routes for converting glycerol into high commercial value products. The production of propylene glycol by catalytic hydrogenolysis of glycerol can be carried out ...

Aiming at expanding the scale of solid-state fermentation processes (SSF), it is necessary to develop and improve appropriate bioreactors. Of note are the packed-bed bioreactors (PBBs), which have already been studied ...

Strategies to reduce CO2 emissions and control the increase in atmospheric levels of this gas are urgent. A promising approach to help minimize the accumulation of CO2 in the atmosphere and the corresponding negative ...

In the environmental and energy context, fuel cells are promising devices for the conversion of clean energy, with hydrogen being the most used fuel. However, its storage and distribution impose some difficulties, in ...

This thesis evaluated the application of Ni-, Fe- and Ni-Fe/MgAl2O4 catalysts in Ethanol Steam Reforming (ESR), Ethanol Steam Reforming with hydrogen gas (ESRH), Methane Dry Reforming (RSM), Methane Steam Reforming (RVM) ...

In this work, the functionalization with aminopropyl-trimethoxysilane (APTMS) of aluminosilicates precursors of the Na-LTA zeolite was explored in the synthesis of basic catalysts for the Knoevenagel condensation. The ...
