Sustainable polypropylene chair: A life cycle assessment and cost analysis of industrial production

open access: yesEnvironmental Progress &Sustainable Energy, EarlyView.
Abstract Due to their multiple properties, including flexibility, lightness, and strength, thermoplastics are an essential material in the development of processes at both industrial and domestic levels. However, thermoplastics are often derived from polymers synthesized using non‐renewable petroleum resources. This has environmental consequences.

Chest ultrasonography to assess the kinetics and efficacy of talc pleurodesis in a model of pneumothorax: an experimental animal study

open access: yesERJ Open Research, 2018
Talc pleurodesis is used to avoid recurrences in malignant pleural effusions or pneumothorax. The lack of lung sliding detected by chest ultrasonography (CUS) after talc application is indicative of the effectiveness of pleurodesis.

Evidence From Microscopy and U–Pb Geochronology as a Clue to the Influence of the Cretaceous Magmatism in the Diagenesis of Pre‐Salt Carbonate Reservoirs in the Santos Basin (Brazil)

open access: yesGeological Journal, EarlyView.
Carbonates from Santos Basin revealed U–Pb ages correlated with basalt ages (A), suggesting that they were formed during magmatic events. These events placed hot CO2 in the reservoir, which, when mixed with carbonate‐rich cold water (B), led to thermal convection, enabling the formation of the U contained in the carbonates.
