Hydrochar from sugarcane industry by-products: assessment of its potential use ...
Fregolente, Laís Gomes; Santos, João Vitor dos; Mazzati, Felipe S.; Miguel, Thaiz Batista Azevedo Rangel; Miguel, Emilio de CastroBackground: Hydrothermal carbonization (HTC) is a thermochemical process to convert biomass in carbon-rich materials (hydrochar). The use of sugarcane industry by-products in HTC has been evaluated, generating a hydrochar rich in nutrients, which could be used as a soil conditioner. We raised the hypothesis that the application of hydrochar in soil can improve its nutrient characteristics, bringing a better env...
Toxicity evaluation of process water from hydrothermal carbonization of sugarca...
Fregolente, Laís Gomes; Miguel, Thaiz Batista Azevedo Rangel; Miguel, Emilio de Castro; Melo, Camila de Almeida; Moreira, Altair BeneditoHydrothermal carbonization (HTC) is a thermochemical process carried out in an aqueous medium. It is capable of converting biomass into a solid, carbon-rich material (hydrochar), and producing a liquid phase (process water) which contains the unreactive feedstock and/or chemical intermediates from the carbonization reaction. The aim of this study was to evaluate the characteristics of process water generated by...
Hydrochar as protein support: preservation of biomolecule properties with non-c...
Castro, Manuela Oliveira; Santiago, Mayara Queiroz de; Nascimento, Kyria Santiago do; Cavada, Benildo Sousa; Miguel, Emilio de CastroIn this work, the ConBr lectin was non-covalently immobilized onto hydrochar (HC). This carbonaceous material was produced by the hydrothermal carbonization of glucose and then put to interact with the lectin, aiming to immobilize the biomolecule via electrostatic interactions. Samples obtained after the interaction were characterized by CHNS elemental analysis, scanning electron microscopy and Fourier transfor...
Photoelectrodes with titanate nanotubes sensitized by mesoporphyrin derivative ...
Souza, Antonio Paulo Santos; Almeida, Ana Fabíola Leite; Conegero, Leila de Souza; Viana, Bartolomeu Cruz; Ferreira, Odair PastorTitanate nanotubes (TiNTs) with the chemical composition Na2Ti3O7.nH2O (NaTiNT) were obtained through a hydrothermal method in highly alkaline medium. Protonated titanates nanotubes (H-TiNTs), with the composition H2Ti3O7.nH2O, were prepared by ion exchange reaction through a suspension of Na2Ti3O7nH2O nanotubes in HCl medium, promoting the exchange of Na+ ions by H+. Both Na2Ti3O7.nH2O and H2Ti3O7.nH2O produc...
