Compósito magnético de matriz vítrea bioativa para hipertermia
(Universidade Federal de São Carlos, 2020-03-19)
Bone cancer is a rare type of neoplasm, but with high rates of new cases annually. With several therapies available for this pathology, a controlled hyperthermia technique is promising. This technique uses the response of ...
Estudo das propriedades mecânicas, térmicas e de transporte do compósito com carbonato de cálcio nano e microparticulado em polipropileno
(Universidade Federal de São Carlos, 2011-03-04)
In this work were determined and compared to mechanical, thermal and barrier of the polypropylene composites containing micropartilate and microparticulate calcium carbonate. To prepare the composites, the filler was ...
Simulação numérica do processo de secagem de concretos refratários em aplicações tecnológicas
(Universidade Federal de São Carlos, 2022-03-21)
Refractory ceramics are used in high temperatures due to their unique properties that enable a high thermal and chemical stability, mechanical strength, thermal properties and others. These materials are split into two ...
Avaliação dos agregados de resíduos da construção civil em matriz geopolimérica visando aplicação em pisos intertravados
(Universidade Federal de São Carlos, 2022-04-14)
The production of Portland cement (PC) is seen as aggravating the environment,
so scientists and engineers look for alternatives to replace this type of binder.
Geopolymers have the potential to replace CP, as it aims ...
Cristalização e relaxação em vidros óxidos uma tentativa de solução do Paradoxo de Kauzmann
(Universidade Federal de São Carlos, 2021-09-03)
The quest for a solution to Kauzmann’s Paradox has been a lifelong
journey for many glass scientists over the last seventy years. The idea that this
paradox may violate the Third Law of Thermodynamics is ...
Síntese de nanopartículas de CuO e aplicações catalíticas
(Universidade Federal de São Carlos, 2024-03-28)
Global population growth, reaching 8 billion people in November 2022, will continue to impose significant pressures on industrial production, agriculture, urban mobility, and energy demand. Coupled with the depletion of ...
Caracterização reo-óptica da interação entre desenovelamento e desenrosco de cadeias poliméricas em fluxo cisalhante
(Universidade Federal de São Carlos, 2024-07-04)
Rheo-optical studies involve monitoring the flow of polymers by measuring their optical properties. In the case of pure polymeric fluids, flow birefringence can be used to quantify the molecular chain orientation. This ...
Vitrocerâmicas de silicato de lítio com gradientes microestruturais - simulações e experimentos
(Universidade Federal de São Carlos, 2022-08-08)
The microstructure of glass-ceramics (GCs) depends on their chemical
composition and thermal history, from the cooling of the precursor glass to the
heat treatments. In glass production, the cooling rate on the surface ...
