Biobased Lubricants from Chemical Modification of Epoxidized Soybean oil

The growing environmental concerns associated with conventional petroleum-based lubricants have driven the search for sustainable alternatives derived from renewable resources. In this context, vegetable oil-based biolubricants have emerged as promising candidates, particularly for applications with a high risk of environmental exposure. However, their widespread industrial implementation is still limited by ch...

A novel paradigm for mutual promotion of mechanical and self lubricant properti...

Green self-lubricating films are considered a promising and environmentally sustainable approach for reducing friction and wear in tribological systems. This dissertation addresses the design of nitride-based coatings in which mechanical strength and tribological performance are improved through controlled microstructural and architectural design. The underlying concept involves the incorporation of a soft lubr...

Land Management, Microbiomes, and Soil Functioning: Integrating Evidence Synthe...

Soil functioning underpins sustainable agriculture and soil-derived ecosystem services, yet understanding how land management reshapes soil biological communities and translates into functional outcomes remains challenging. This limitation is particularly evident across soil biological communities, from soil fauna to microbiomes, whose responses to management are increasingly documented but remain fragmented ac...

A Escuta como Leitura Aural: a medialidade literária do audiolivro

This study employs the narcofeminism framework to explore opportunities for develo...
