Transport of components in the separation of ethanol from aqueous dilute solutions by forward osmosis
(2018) [Journal article]Membrane-based technologies have been considered for separation of ethanol/water mixtures as an alternative to thermal based separations. In this work, we consider forward osmosis (FO) for ethanol separation from aqueous ... -
Incorporation of astrocaryum vulgare (tucuma) oil into PCL electrospun fibers
(2021) [Journal article]The aim of this study was to incorporate tucuma oil (Astrocaryum vulgare) into PolyCaprolactone (PCL) electrospun fibers and evaluate its physicochemical properties and cell viability. FTIR and DRX confirmed that tucuma ... -
A fair comparison between bismuth catalysts for application in photodegradation under visible and solar light
(2019) [Journal article]Three different bismuth catalysts (Bi2WO6, BiOI and BiVO4) were synthesized using solvo- and hydrothermal methods. Different reaction times, calcination and the addition of poly (vinyl pyrrolidone) during synthesis were ... -
Weldability test of AWS A5.9 ER385 filler metal deposited through MIG-VP on ASTM A36 substrate
(2025) [Journal article]Objective: The objective of this investigation is to validate the MIG-PV process using AWS A5.9 ER385 filler metal on ASTM A36 steel through solidification cracking and hydrogen-induced cracking tests, as well as to evaluate ... -
Simultaneous removal of chlorides and calcium from EAF dust wastewater
(2025) [Journal article]This research investigates the sorption efficiencies of various adsorbents—synthesized Hydrotalcite, natural zeolite Clinoptilolite, synthetic zeolite, and waste sludge from aluminum anodic oxidation—for simultaneous removal ... -
A fractal analysis of the size effect in quasi-brittle materials : experimental tests and peridynamic simulations
(2025) [Journal article]In the design of structures involving quasi-brittle materials such as concrete, it is essential to consider the scale dependence of the mechanical properties of the material. Among the theories used to describe the phenomenon ... -
Evaluation by means of electrochemical impedance spectroscopy of the transport of phosphate ions through a heterogeneous anion-exchange membrane at different pH and electrolyte concentration
(2023) [Journal article]Electrodialysis is an innovative technique to reclaim phosphates from municipal wastewater. However, chemical reactions accompany the transport of these ions through ion-exchange membranes. The present study investigates ... -
Zirconium oxide and tannic acid-based nanoceramic coatings for corrosion protection of cold-rolled steel
(2024) [Journal article]Current research has focused on investigating substances that are less toxic and harmful to human health and the environment. In the context of natural compounds for corrosion protection, this study examined the incorporation ... -
Autoclaved aerated concrete reinforced by polymeric pins
(2024) [Journal article]Autoclaved Aerated Concrete (AAC) is a lightweight and sustainable building material known for its thermal insulation and acoustic properties. However, its relatively low mechanical strength limits its use in load-bearing ... -
Estudo do processo MIG/MAG-PV com arame AWS A5.9 ER316LSI : influência da %EN na morfologia e diluição de revestimento em aço ASTM A36
(2025) [Journal article]A investigação dos parâmetros do processo de soldagem a arco elétrico é essencial para a viabilidade do revestimento, uma solução eficiente em comparação ao componente maciço, tanto do ponto de vista econômico quanto em ...
