The present study aimed to obtain functionalized nanocellulose through the oxypropylation reaction. Thereunto, the cellulose was submitted to an initial activation step with a sodium hydroxide solution, and then the reaction ...

Interest in the use of starch for biodegradable films is growing due to being a natural, renewable, abundant and low cost source. However, starch films generally have low values of mechanical properties. Thus, this work ...

The population increase has caused several environmental problems such as contamination of aquatic bodies by organic compounds and the emission of CO2 in the atmosphere. An alternative to mitigate these impacts is Heterogeneous ...

Fission Track Thermochronology (TTF) has been used for decades as a technique that makes it possible to date and infer the thermal history of rocks in regions of geological interest, from different minerals. The methodology ...

In the last years, sustainable materials that provide less environmental impact are gaining special attention. In this context, cellulose, a natural and abundant polymer from several renewable vegetable and microbial ...

Titanium-based implants are being commonly used in the field of biomedicine due to their attractive biocompatibility and their mechanical properties that contribute to a better performance of the material. This dissertation ...

Cellulose, being a biodegradable material, flexible and with good mechanical resistance, has been attracting great interest in studies, as it is a biopolymer from a renewable source and widely available in nature. It can ...

In recent decades, studies and discoveries related to carbon nanostructures have been intensified, mentioning carbon nanotubes, graphene and their derivatives. These structures have unique physical and chemical properties, ...

Using the LbL self-assembly technique, an ITO electrode was modified with gold nanoparticles stabilized with PAH and copper phthalocyanines, for the detection of cadmium (Cd) and lead (Pb). Using the UV-Vis technique it ...

The pollution of drinking water due to industrial activity in recent decades can have consequences for the supply and health of the population. Advanced oxidative processes (AOPs) such as heterogeneous photocatalysis are ...
