(INVITED)Laser-driven white light with tunable low-colour temperature based on novel ZrO2-doped (Gd,Lu)2O3:Eu red-emitting transparent ceramics

open access: yesOptical Materials: X, 2022
Novel red-emitting ZrO2-doped (Gd,Lu)2O3:Eu transparent fluorescent ceramics were fabricated via a vacuum sintering method. The f–f transitions of Eu3+ in the ZrO2-doped (Gd,Lu)2O3:Eu transparent fluorescent ceramics have much higher intensity than the ...

Is an Apple an Orange? A Large Language Model Benchmark for Candidate Term Extraction and Subclass Decisions Against Upper Ontologies in Engineering and Materials Science

open access: yesAdvanced Engineering Materials, EarlyView.
Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Symbolic Regression and Multi‐Objective Optimization of the Flory–Huggins Interaction Parameter for Hydrogels

open access: yesAdvanced Engineering Materials, EarlyView.
We develop a data‐driven method to derive the mathematical expressions of the Flory–Huggins interaction parameter χ for the swelling behavior of temperature–responsive hydrogels. Starting from initial assumptions of χ, our workflow combines Bayesian optimization, Flory–Rehner theory, and symbolic regression to generate candidate χ expressions.

Workflow for Design of Experiments‐Based Modeling of Species Transport and Growth Kinetics in GaN Hydride Vapor Phase Epitaxy

open access: yesAdvanced Engineering Materials, EarlyView.
A novel workflow for investigating hydride vapor phase epitaxy for GaN bulk crystal growth is proposed. It combines Design of experiments (DoE) with physical simulations of mass transport and crystal growth kinetics, serving as an intermediate step between DoE and experiments.

Influência da adição de resíduo (lodo) de estação de tratamento de águas nas propriedades e microestrutura de cerâmica vermelha Influence of the addition of water treatment sludge on the properties and microstructure of red ceramic

open access: yesCerâmica, 2008
As estações de tratamento de águas (ETA) geram grandes quantidades de resíduo (lama). Este resíduo quando descartado nos sistemas hídricos provoca impacto ambiental negativo.
