Improving the wear resistance of high chromium cast iron through high entropy alloys concepts and microstructure refinement
(2023) [Artigo de periódico]High Chromium Cast Iron (HCCI) has demonstrated its effectiveness as a potential material for applications in severe environments due to its remarkable wear resistance attributed to the volumetric fraction of carbides in ... -
Thermodynamic modelling of cements clinkering process as a tool for optimising the proportioning of raw meals containing alternative materials
(2023) [Artigo de periódico]The valorisation of waste or by-products in Portland clinker production is a promising alternative for developing sustainable cements. The complexity of the chemical reactions during clinkering demands an adequate dosing ... -
Damage evolution in quasi-brittle materials : experimental analysis by AE and numerical simulation
(2023) [Artigo de periódico]This work investigates the extension of a total-collapse prediction method to include local failures in quasi-brittle materials as they undergo damage processes. The analysis is experimentally conducted with acoustic ... -
Evaluation of anthocyanins and other phenolic compounds extraction from blueberry processing waste with acidified water
(2017) [Artigo de periódico]Anthocyanins are natural pigments andthey are responsible for the blue-to-red coloration of flowers, fruits and leaves. These phenolic compounds are also known to be beneficial to human health. Due to their instability ... -
Development by extrusion of composite films based on Poly(Lactic Acid)/Babassu Mesocarp Flour
(2024) [Artigo de periódico]The objective of this manuscript was to investigate the influence of different Babassu Mesocarp Flour (BMF) contents (3, 5, 8, and 10% by weight) on the physical and surface properties of the Poly(Lactic Acid) (PLA) matrix. ... -
