Permlastic® is a polysulfide-based impression material widely used by dentists in Brazil. It is composed of a base paste and a catalyzer containing lead dioxide. The high toxicity of lead to humans is ground for much ...

The development of smart and eco-friendly fertilizers is pivotal to guarantee food security sustainably. Phosphate rock and struvite are promising alternatives for P fertilization; nevertheless, the solubility of these ...

Beyond Li-ion batteries, one of the most promising technology is the Lithium-Sulphur (Li-S) not only for its higher theoretical energy density (about 2600 Wh kg−1) but because sulfur is relatively inexpensive and non-toxic. ...

The interaction of polysulfides with graphene layers substitutionally modified with heteroatoms is analyzed using first-principles calculations, with the aim of using these structures to prevent polysulfide migration in ...

High-power high-density lithium rechargeable batteries are necessary to meet the energy demand of electric vehicles and high-power stationary grids. Here, we present a straightforward method for obtaining carbon nanofibers ...

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 ...

Lime sulphur is used worldwide in agriculture to control pests and diseases. Our objective was to determine the effect of lime sulphur applications in an orange orchard on soil chemical properties and foliar nutrients after ...

The commercial development of high-energy lithium-sulfur (Li-S) batteries is still hampered by the irreversible active material loss and fast capacity decay triggered by the dissolution of polysulfide species and the ...
