Formulação e estudo da citocompatibilidade de hidrogéis termossensíveis contendo partículas bioativas para aplicação em regeneração óssea
(Universidade Federal de São Carlos, 2022-07-29)
Although the osteogenic properties, there are still some limitations to employing bioactive glasses (BG) in the human body, such as potential cytotoxicity and a lack of controlling the morphology of BG particles.
Furthermore, ...
Estudo computacional de nanoestruturas de ouro funcionalizadas com moléculas orgânicas quirais
(Universidade Federal de São Carlos, 2023-12-14)
In this present work was carried out the computational study of the functionalization of gold nanoparticles in spherical shape with L-amino acids using molecular dynamics simulations and geometry optimizations at DFTB level ...
0D and 2D nanomaterials based on Graphene quantum dots and MXenes: synthesis, characterization and application in sensors and supercapacitors
(Universidade Federal de São Carlos, 2023-10-20)
Graphene Quantum Dots (GQDs) are small fragments of one or a few layers of graphene with lateral dimensions inferior to 100 nm. GQDs present some characteristics similar to those of graphene, such as a high surface area/volume ...
Investigating the potential of polysulfides obtained via inverse vulcanization as sustainable fertilizers
(Universidade Federal de São Carlos, 2022-11-07)
Global food security is one of the biggest challenges we face today, and to this end, establishing sustainable strategies towards the development of more efficient and safer agricultural products is indispensable. Sulfur ...
Estudo empírico-teórico de compósitos baseados em polímeros condutores para conversão e armazenamento de energia
(Universidade Federal de São Carlos, 2018-10-26)
The fast obsolescence of still functional devices causes an extensive e-waste generation and an exacerbated natural resources consumption for the manufacture of new products. In this sense, the development of abundant ...
Modificação de semicondutores de Sb2Se3 com co-catalisadores de MoSx e Pt para a produção de hidrogênio verde via water splitting solar
(Universidade Federal de São Carlos, 2022-11-23)
Sb2Se3 semiconductors have been shown to be excellent photocathodes with attractive optoelectronic properties when compared to other photoabsorbers commonly used. However, its photocorrosion in aqueous media prevents it ...
Reação de redução de compostos nitrogenados: de aspectos fundamentais em monocristais de Pt à utilização de nanopartículas bimetálicas
(Universidade Federal de São Carlos, 2022-02-23)
Because of the high consumption of nitrogen-based compounds by both industry and agriculture, there is an imbalance in nitrogen cycle and the nitrate and nitrite reduction reaction can be a solution. These processes are ...
Esfoliação e funcionalização de nanofolhas de MoS2: desenvolvimento de novos materiais elastoméricos
(Universidade Federal de São Carlos, 2021-09-30)
Two-dimensional materials, such as MoS2, have been extensively studied in recent decades due to their excellent properties in electronics, electrocatalysis, optics and mechanics. A major focus in recent research resides ...
Estudo teórico e experimental da interação de elétrons com moléculas de interesse astroquímico
(Universidade Federal de São Carlos, 2021-09-08)
We performed a theoretical and experimental investigation on electron (e⁻) scattering by molecules of astrochemical interest. Theoretically, we obtained elastic differential (DCSs), integral (ICSs) and momentum-transfer ...
