Abstract: AACS Applied Nano Materials, Dec., 2023The pursuit of effective and safe vaccines against severe acute respiratory syndrome caused by SARS-CoV-2 has posed a significant challenge for science in recent years, allowing the emergence of new vaccine strategies and platforms. Here, we present a coronavirus disease candidate vaccine based on Leia mais…
Resumo: O presente estudo avaliou a influência da temperatura na corrosão influenciada por microrganismos (CIM) sob condição estática e anaeróbica (~10 ppb) por um período de 45 dias. Os ensaios foram realizados em biorreatores e como meio foi utilizado água do mar natural esterilizada e enriquecida com solução nutritiva, em Leia mais…
Abstract: Wireless communications with greater transmission capacities are possible in the millimeter wave (mmWave) region. However, to overcome the significant propagation losses in this frequency band, it is necessary to employ more efficient and intelligent antennas based on MIMO and beam-steering phased array technologies. This paper demonstrates the fabrication of Leia mais…
Abstract: Fructooligosaccharides (FOS) are fructose oligomers beneficial to human health and nutrition for prebiotic sugars. Their production occurs by a transfructosylation reaction in sucrose molecules catalyzed by fructosyltransferase enzymes (FTase, E.C.2.4.1.9) adhered to microbial cells. The purpose of this work was to study the preparation, enzymatic activity, and stability of Leia mais…
Abstract: White-rot fungi (WRF) synthesize ligninolytic extracellular oxidative enzymes such as laccase (Lcc), which has been described as one of the most interesting types of redox enzymes that can improve microbial fuel cell (MFC) performance. Therefore, and in order to test that performance, WRF Trametes versicolor MUM 04.100 was immobilized Leia mais…
Abstract: Electrospun nanofiber scaffolds mimic the structure of the natural extracellular matrix, making them promising for application in tissue engineering. Based on this, the biopolymers poly(ε-caprolactone) (PCL) and gelatin, with good mechanical and biological properties, respectively, were electrospun with acetic acid as the only solvent, without the crosslinking process in Leia mais…
Abstract: Probiotic microorganisms are a promising alternative to antibiotics in preventing and treating bacterial infections. Within the probiotic group, the lactic acid bacteria (LAB)stand out for their health benefits and for being recognized as safe by regulatory agencies. However, these microorganisms are sensitive to various environmental conditions, including the acidic Leia mais…

Resumo: A energia do ultrassom como método físico de prevenção/redução de incrustação por CaCO3 tem sido avaliada nos últimos anos, sendo que quando transferida para o sistema provoca o fenômeno de cavitação, influenciando diretamente a precipitação do CaCO3, alterando o tamanho e as fases formadas, a quantidade de material precipitado, Leia mais…
Resumo: Em ensaios tipo “Tube Blocking Test–TBT” obtém-se como resposta o tempo demandado para que a precipitação do carbonato de cálcio ocorra e provoque, através da avaliação da perda de carga entre a entrada e a saída do reator, o bloqueio gradativo da área da seção transversal do reator. Este Leia mais…
