Estudo teórico da influência da adição de adesivante nas propriedades físico-quimicas do polipropileno reforçado com fibras de vidro
(Universidade Federal de São Carlos, 2023-07-20)
Fiber-reinforced polymeric composites are widely used today, being applied in several areas such as aeronautics, automotive, military, medical, among others. However, some polymers present low adhesion in the interfacial ...
Desenvolvimento de nanocompósito de poliamida 6 e óxido de grafeno e união com alumínio 6061 por sobremoldagem por injeção
(Universidade Federal de São Carlos, 2023-04-28)
Polymer-metal hybrid structures are presented as an alternative to the transportation industry, since they are able to combine high mechanical strength and lightness. The present study focuses on obtaining hybrid joints ...
In situ chemical oxidation of ciprofloxacin by activated peroxymonosulfate using nanometric MnOOH: investigation of operational parameters and changes on the catalyst surface
(Universidade Federal de São Carlos, 2023-05-24)
Nanometric MnOOH compound was synthesized by a green approach, characterized, and used to remove ciprofloxacin (CIP) antibiotic by in situ chemical oxidation using peroxymonosulfate (PMS). The effects of varying concentrations ...
People s awareness of circular economy: scale development and relationship with social influence, psychological barriers, and favourable evaluation of sustainable development
(Universidade Federal de São Carlos, 2023-04-13)
Circular Economy (CE) encompasses strategies that aim to decouple economic activity from finite resource consumption and eliminate waste from the system as a matter of principle. Supported by a transition to renewable ...
Teorema da esfera suave via fluxo de Ricci
(Universidade Federal de São Carlos, 2023-08-04)
The goal of this dissertation is the theoretical development of the Ricci flow, a differential equation over a family of Riemannian metrics on an arbitrary differentiable manifold, and its use in the proof of the so-called ...
Síntese de catalisadores básicos na presença de surfactantes hexadeciltrimetilamônio
(Universidade Federal de São Carlos, 2023-06-12)
The synthesis of two basic catalysts — CTA-MCM-41 and ZIF-8 — were studied in the presence of the surfactant hexadecyltrimethylammonium bromide (CTAB), which forms micelles in aqueous dispersions. The catalysts were ...
Desenvolvimento de compósitos de polímero ionomérico e metal baseados em poli(éter-éter-cetona) sulfonados
(Universidade Federal de São Carlos, 2023-07-26)
Ionic polymer-metal composites (IPMCs) are smart and bio-inspired materials that have a metal/polymer/metal sandwich structure. These are capable of deforming in response to electrical stimuli and vice versa, being promising ...
