The delivery of nucleic acids to cells is considered a crucial step for the success of genetic modifications aimed at therapeutic purposes or production of genetically modified animals. In this context, nanotechnology is one of the most promising fields of science, with the potential to solve several existing problems. Nanostructures have desirable...
Abstract: In the last decades, devices were developed, to monitor changes in the concentration of volatile componds of the atmosphere. These devices, denominated sensors, have several applications in the industry, i.e., controlling the release of nocive substances to the environment, or even in the medicine, providing early detection of diseases an...
Abstract: This work presents a study or organic memory devices like WORM (Write Once Read Many times) having as active layer thin films of epoxy resin nanocomposites and single-layer or multi-layer carbon nanostructures. Epoxy resin was used as polymer matrix for its many advantages allowing the possibility of using the same component in the fabric...
Organic-inorganic hybrid coatings for corrosion protection of aluminum alloys are promising alternatives to the current methods based on chromate passivation. From the optimization of polymerization efficiency (Ep) of the organic phase and using the sol-gel process, hybrids with different polymer/silica ratios and cerium concentrations were prepare...

Abstract: Due to the increasing production and applications of AgNP in consumer products, AgNP are expected to be, directly or indirectly, released into natural environments, representing a potential threat to the biota and humans. An increasing number of studies have described the toxic potential of AgNP in cells and organisms. However, co-exposur...
The fiber of caroa plants has a high quantity of cellulose (≈ 65%) that can be used as a renewable energy source to produce nanocellulose and second-generation ethanol (2G). The aim of this research was to obtain nanocellulose and ethanol from caroa fiber using methods with minimal detrimental effects on the environment. Hydrothermal pretreatment t...
As fibras de caroá contêm elevado teor de celulose (≈ 65%), podendo ser utilizada como fonte renovável de energia para a produção de nanocelulose e etanol de segunda geração (2G). Desse modo, objetivou-se com esta pesquisa obter nanocelulose e etanol a partir da fibra de caroá, por meio de uma metodologia capaz de gerar menor impacto negativo ao am...
