Carbon foam composites based on expanded graphite for electrochemical application
(2020-03-01)
Polymer composites containing modified graphite structures as fillers have been successfully processed exhibiting attractive features for different applications. Carbon foams derived from polymer precursor is brittle and ...
Characterization of expanded polystyrene and its composites by supercritical carbon dioxide foaming approach
(2021-01-01)
Supercritical carbon dioxide (scCO2) has been used as a physical blowing agent to produce polymer expanded materials. Firstly, a statistic study was performed to determine the neat polystyrene (PS) expansion parameters, ...
Mineral composites: stay-in-place formwork for concrete using foam 3D printing
(2023)
Optimizing the shape of concrete construction elements is significant in reducing their material consumption and total weight while improving their functional performance. However, the resulting non-standard geometries are ...
Residues from agroindustry as reinforcement in foams based on PBAT/PLA blend
(American Chemical Society, 2020)
Fracionamento de lignina proveniente do processo kraft para obtenção de frações com diferentes massas molares e aplicação em materiais funcionais: espumas de carbono.
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Ciência dos Materiais - PPGCM-SoCâmpus Sorocaba, 2023-02-01)
This thesis has three main objectives: (i) To describe an efficient fractionation method for Kraft lignin (KL) to extract large amounts of low molecular weight lignin, which indicates the presence of a higher content of ...
Influence of carbon sources and C/N ratio on EPS production in anaerobic sequencing batch biofilm reactors for wastewater treatment
(ELSEVIER SCI LTD, 2010)
The objective of this work was to evaluate the influence of different carbon sources and the carbon/nitrogen ratio (C/N) on the production and main composition of insoluble extracellular polymers (EPS) produced in an ...
Análise do comportamento de materiais compósitos com relação a variação da espessura do núcleo sob ensaios de flexão
(Universidade Tecnológica Federal do ParanáLondrinaBrasilEngenharia MecânicaUTFPR, 2021-05-13)
Composites are materials formed by the union of other materials in order to increase the resistance to traction, compression, flexion and impact of the materials in question. Sandwich structure is a composite whose geometry ...
Low-density Three-dimensional Foam Using Self-reinforced Hybrid Two-dimensional Atomic Layers
