Effect of Addition of Polyurea as an Aggregate in Mortars: Analysis of Microstructure and Strength
(2022)
The addition of polymers in construction is a new tendency and an important step toward the production of structures with better functional properties. This work investigates the addition of polyurea (PU) as a polymeric ...
Effects of Different Concentrations of Arsine on the Synthesis and Final Properties of Polypropylene
(2022-07-31)
This article studies the effects of arsine on the synthesis and thermal degradation of 4 sam ples of virgin polypropylene (PP-virgin) and proposes reaction mechanisms that allow understanding
of its behaviour. Different ...
Impact of Traces of Hydrogen Sulfide on the Efficiency of Ziegler–Natta Catalyst on the Final Properties of Polypropylene
(2022-09-19)
Sulfur compounds are removed from propylene through purification processes. However,
these processes are not 100% effective, so low concentrations of compounds such as H2S may be
present in polymer-grade propylene. This ...
Identification and Quantification of Microplastics in Effluents of Wastewater Treatment Plant by Differential Scanning Calorimetry (DSC)
(2022-04-20)
In this research, the presence of microplastics was detected through a differential scanning
calorimetry (DSC) analysis of three wastewater treatment plants. One of these plants applied
only a preliminary treatment stage ...
