Roselena Faez is a full professor at UFSCar- Araras and leader of the Research Group on Polymeric and Biosorbent Materials at CNPq (MPB). She is Chemist (1993, IQ-UNESP Araraquara) and PhD in Sciences (1999, IQ-UNICAMP) with a sandwich doctorate at the German Institute of Rubber (DIK) in Hannover and post-doctorate at the Materials Division of the Technological Center of Aeronautics ( 2001). She did a sabbatical at the University of California-Davis (UCDavis) (2016-2017). She has experience in the field of polymeric materials, working in the synthesis, processing and characterization of polymers for application in agriculture and the environment, working with an emphasis on sustainability, thinking about optimizing the process of obtaining materials and focusing on SDGs (2, 5, 9, 12, 13 ). She advises the permanent staff of the PPGs Agriculture and Environment at UFSCar-Araras and Materials Engineering and Science at USP-Pirassununga. She was director of the Materials Division of the Brazilian Chemical Society (2014-2016). She is a member of the Board of Directors of ABPol (2021-205). She is part of the SBQ Women's Nucleus (2022-2024). (Source: Lattes Curriculum)

The main objective of this project is the preparation, characterization, and application of polymeric structures as host matrices for programmable release nutrients in soil and plant. The project cover three main goals: 1) Preparation of nanocellulose/nutrient (NC/nutrient) and chitosan/nanocellulose/nutrient () microparticles by spray drying; 2) Thermal processing of PHB/starch and PHB/T…
The main goal of this project is the preparation, characterization and application of hybrid polymeric materials for nutrients release in soil and plant. The project comprises three main targets: 1) Preparation and characterization of hybrids polymeric materials as microspheres and with macronutrients (nitrogen and potassium), 2) Evaluation of the mechanism and kinetics of the release of …

Enhanced efficiency fertilizers (EEFs) appear as an alternative for the more efficient application of fertilizers, as they attenuate environmental impacts and keep the nutrients needed for the stages of plant growth available for longer. A current major challenge is the development of EEFs from materials that degrade in the environment after fulfilling their nutrient release function. Thu…
Given the population increase, there is a need to expand food production. In agriculture, fertilizer is used to supply nutrients to the plants and increase productivity, but at the same time, there is a problem: nutrient leaching. As a solution we have the programmed release of fertilizers, which supplies the need for nutrients at the initial and subsequent moments, and, as a consequence,…
Encouraging the development of sustainable agriculture is very important to reduce the negative impacts of overuse of the land. In this way, the use of intelligent materials that release nutrients in a prolonged way, associate with sustainable policies, can contribute to greener agriculture. It is interesting these materials are obtained through green processes and use biodegradable mater…
Controlled-Release Fertilizer (CRF) research has grown in recent decades due to the innumerable advantages to Agriculture, such as increasing the efficiency of fertilizer use, providing regular and continuous level for plant nutrition over time. However, the use of non-biodegradable polymers as matrix to cover and encapsulate CRF has been debated because of the residue generated. The use …

Enhanced efficiency fertilizers (EEFs) have the potential to improve the agricultural systems by specific formulation of materials which has mechanisms of slow or controlled release. Studies have shown that the use of EEFs promote an increase in nutrients use efficiency, reduces the doses of application and the frequency of the application along with the cost of the fertilizer. Because of…
Programmable fertilizer has been intensively studied in the last decades to deliver nutrients in a regular and continuous way to plants. Parallel to these efforts, cellulose-based materials have attracted attention. There is a wide number of recent works involving the development of materials containing cellulose nanoparticles (CNs). CNs have hydroxyl groups on its surface with great pote…
Controlled delivery system is a remarkable research area since with strategic materials the chemical substances such as agrochemical can target the soil and plant with improve efficacy. Designing polymeric composite materials with synergic properties of the components is a tool to get a peculiar behavior. This project aims to investigate the synthesis of controlled release biocomposites f…
