Avaliação das propriedades de armazenagem de hidrogênio através de reação sólido-gás e eletroquímica da liga multicomponente (TiNb)(CrMnFe)₂ com estrutura de Fase Laves tipo C14
(Universidade Federal de São Carlos, 2023-02-24)
Hydrogen is critical for storage and transport of renewable energy. Because it is low-density gas, one of the biggest challenges of its widespread use as an energy vector is in its hardly storage. Metal hydrides are strategic ...
Síntese, caracterização e avaliação ecotoxicológica de nanocompósito de Ag3VO4/Ag
(Universidade Federal de São Carlos, 2023-03-20)
Historically, the development of new methods of synthesizing materials has been linked to the development of societies, mainly due to the ability to promote changes in materials and enable new types of technological ...
Efeito do inoculante Al-Nb-B na microestrutura e propriedades mecânicas da liga AA2017 fabricada por fusão em leito de pó a laser
(Universidade Federal de São Carlos, 2023-01-24)
The blending of finer powders of Ti, Zr, Ta, Sc, and Nb compounds as inoculants has been a promising strategy to modify precipitation-hardened aluminum alloys for laser-based powder bed fusion process (L-PBF), promoting a ...
Avaliação da fermentação alcoólica extrativa em diferentes temperaturas com remoção de etanol por arraste com CO2
(Universidade Federal de São Carlos, 2023-02-23)
By reducing the fermentation temperature, the inhibitory effect of ethanol is also reduced, resulting in wines with higher ethanol contents, but with a significant decrease in ethanol productivity, due to the negative ...
Bioprospecção de Streptomyces sp. do Cerrado para controle biológico da mancha-alvo da soja
(Universidade Federal de São Carlos, 2023-03-24)
The Brazilian tropical savannah (Cerrado) comprises the second largest Brazilian biome and is characterized by the high incidence of endemic species that makes it an interesting source of microorganisms of biotechnological ...
Síntese de ésteres graxos de açúcar catalisada por derivados imobilizados-estabilizados de candida antarctica lipase B
(Universidade Federal de São Carlos, 2023-03-21)
The biotechnology industry is increasingly seeking to deploy high productivity and stable biocatalysts for commercial-scale production of bioproducts. In addition, with global warming, enzyme-based production systems using ...
Design science research em gestão de operações: proposta e avaliação de um modelo de referência para projetar artefatos
(Universidade Federal de São Carlos, 2023-03-08)
Despite the high potential contribution of Design Science Research (DSR) in the Operations Management (OM) field, there are still few studies published using this approach. Furthermore, the reference models for conducting ...
Ultracold bosons in random lattice potentials
(Universidade Federal de São Carlos, 2023-04-06)
The Bose-Hubbard model describes short-range interacting spinless bosons on a random lattice. This model is realized in ultracold atomic systems where quantum phase transitions can be observed. When loaded into a deep ...
Polipropileno modificado com semicondutores a base de prata: compósitos com alta potencialidade contra SARS-CoV-2 e outros patógenos
(Universidade Federal de São Carlos, 2023-03-30)
The worldwide outbreak of the coronavirus (COVID-19) pandemic and other
emerging infections is difficult and sometimes impossible to treat, making them
one of the major public health issues of recent times. It is ...
Especiação de arsênio em água e tecido de peixe empregando extração em fase sólida (SPE) e espectrometria de emissão óptica com plasma acoplado indutivamente (ICP OES)
(Universidade Federal de São Carlos, 2023-02-28)
The adverse effects caused by potentially toxic elements on the environment and human health vary according to the elements’ species, which differ in terms of toxicity. Arsenic (As) exposure is a global public health ...
