Síntese, caracterização e adesão celular de uma nova classe de hidrogéis injetáveis, termo sensíveis e biodegradáveis
(Universidade Federal de São Carlos, 2014-03-10)
Hydrogels have been widely studied, especially as injectable materials for applications as biomaterials. These hydrogels may possess thermosensitive features near body temperature (LCST Lower Critical Solution Temperature ...
Análise da eficiência energética das biomassas utilizadas em fornos cerâmicos na região de Tatuí-SP
(Universidade Federal de São Carlos, 2015-02-26)
Energy production in the form of heat from the burning of lignocellulosic materials is an interesting form of waste recovery. However, one needs to know the physical and chemical characteristics ...
Microplásticos: impacto ambiental de polímeros fotodegradados
(Universidade Federal de São Carlos, 2020-02-03)
Plastics have been studied for their environmental impact, since when discarded in the environment they do not disappear. Over time they degrade and fragment into smaller pieces, reaching the microscale. When exposed to ...
Filmes nanoestruturados para detecção do antígeno prostático específico utilizando nanopartículas de ouro
(Universidade Federal de São Carlos, 2019-02-15)
In the present work, nanostructured films were prepared through the self-assembly techniques for the detection of prostatic specific antigen (PSA), a glycoprotein produced in abnormal levels in case of prostate cancer. Two ...
Filmes automontados de nanopartículas de magnetita e polipirrol na determinação analítica de metilparabeno
(Universidade Federal de São Carlos, 2020-02-20)
Parabens are esters derived from para-hydroxybenzoic acid used as antimicrobials and bactericides in cosmetics, personal hygiene and cleaning products, food and medicines. Side effects have been observed due to the ...

The Sugarcane (Saccharum officinarum L.) is currently one of the main agricultural products. Considering the high production of sugarcane bagasse in Brazil and in the world, the objective was to obtain pre-treated sugarcane ...
Modificação de quitosana com ácido hialurônico e sua blenda com colágeno para aplicação biomédica
(Universidade Federal de São Carlos, 2019-03-08)
As in other areas of application, researchers in the field of biomaterials have been looking for materials from natural sources for the installation of implantable or curative devices, in this sense, a chitosan has been ...
Obtenção de nanocelulose a partir da funcionalização da celulose por oxipropilação
(Universidade Federal de São Carlos, 2020-03-27)
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 ...
Desenvolvimento e caracterização de filmes poliméricos de amido de milho com incorporação de fibras de bagaço de cevada
(Universidade Federal de São Carlos, 2020-03-25)
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 ...
