1. The influence of separately and combined bentonite and kaolinite as binders for pelletization of NaA zeolite from coal fly ash
Abstract Pelletization of zeolitic materials is required to facilitate their practical industrial and commercial applications. Zeolite-NaA was synthesized from fly ash by the fusion method and shaped into spherical granules. Bentonite, kaolinite, and a combination of bentonite with kaolinite were tested as binders with different contents from 5 to 10 wt%. Th

2. Additive Manufacturing towards the Fabrication of Greener Electrochemical Sensors for Antioxidants
Additive manufacturing is an emerging tool that has contributed to the sustainable fabrication of devices in several areas based on the concept of “zero waste”. Considering extrusion-based manufacturing (or 3D printing), polylactic acid (PLA) has been highlighted due to its biodegradability, obtention from renewable sources, and compatibility for 3D prin

3. Spectrophotometric Determination of Allura Red AC and Tartrazine in Food Products Using Hydrophobic Deep Eutectic Solvents as an Environmentally Sustainable Micro-Extractor
This paper reports the application of hydrophobic deep eutectic solvents (HDES) as an environmentally friendly alternative for liquid-phase microextraction (LPME) of Allura Red AC and Tartrazine in food products and the spectrophotometric determination of these analytes. The HDES used in this work were prepared by mixing octanoic acid (OctAc) or decanoic aci

4. Forecasting mass and metallurgical balance at a gold processing plant using modern multivariate statistics
Abstract Knowing the quantity and the quality of products and tailings generated by a beneficiation plant, even before ore processing, can make the mining operations more sustainable, more profitable, and safer. To forecast these values, it is necessary to submit samples to batch tests which mimic the processing workflow used on an industrial scale. Then, th

5. Sustainable production of furfural and 5-hidroximetilfurfural from rice husks and soybean peel by using ionic liquid
Abstract In the current search for renewable energy sources, residual biomass has been highlighted as a potential source of chemical compounds that are currently obtained from petroleum. Among the derivatives obtained from this, 5-hydroxymethylfurfural and furfural are considered key parts in this process as they are key compounds in the fine chemical indust

6. APLICAÇÃO DE NANOPARTÍCULAS DE FERRO ZERO-VALENTE (nFeZ) NA REMEDIAÇÃO DE SOLOS E ÁGUAS SUBTERRÂNEAS CONTAMINADAS: UMA REVISÃO
The remediation of contaminated soil and water is a relevant topic, being the focus of intense research. The use of nanoparticles to degrade contaminants has been consolidated as a sustainable remediation technology, with promising results worldwide. In this scenario, the zero-valent iron nanoparticles (nZVI) which, due to their properties, prove to be an im

7. MULTILEVEL NONLINEAR MIXED-EFFECTS MODEL AND MACHINE LEARNING FOR PREDICTING THE VOLUME OF Eucalyptus SPP. TREES
ABSTRACT Volumetric equations is one of the main tools for quantifying forest stand production, and is the basis for sustainable management of forest plantations. This study aimed to assess the quality of the volumetric estimation of Eucalyptus spp. trees using a mixed-effects model, artificial neural network (ANN) and support-vector machine (SVM). The datab

8. Foreign direct investment in developing economies A study on the productivity spillover effects in Latin America
Abstract Purpose The aim of this study was to investigate how the productivity spillover effects of foreign direct investment (FDI) in the Latin American economies are manifested. Specifically, the paper sought to identify the role of foreign presence and government intervention through an industrial policy on total factor productivity in Latin American cou

12. Converting a Conventional Vehicle into an Electric Vehicle (EV)
Abstract The electric vehicle (EV) is not a recent invention. Between the end of the XIX century and the beginning of the XX century, most motor vehicles were electric, due to their superior reliability and cleanliness, compared to that of vehicles driven by internal combustion engines (ICE). However, with the development of ICEs and the reduction of their p
