Temporal bone 3D models – an innovative approach in otologic surgical training
Sousa Teles, Sofia; Claro, Ana; Ferraria, Lília; Neto, Mariana; Pires, Rafael; Oliveira, Leonor; Dias, Joana; Couto, Ana Miguel; Nelas, RicardoIntroduction: Temporal bone surgery requires high precision due to the complexity of its anatomy. Traditional surgical training with cadavers presents limitations such as scarcity of material, anatomical variability, and high costs. This study explores the use of personalized 3D models of the temporal bone from patients scheduled for otologic surgery as an innovative training tool.Materials and Methods: Persona...
From Ink to Mockup: An Integrated Study of Historical Gall Ink Formulations and...
Nunes, Margarida; Vieira, Joana C.; Costa, Ana Paula; Cabral, Maria Emilia A.; Vieira, Bruno J.C.; Waerenborgh, João Carlos; Nogueira, Isabel I.S.Iron gall inks (IGIs) played a central role as a writing medium in Western countries, leaving behind a vast legacy and significant conservation challenges. This study presents a twofold methodological approach to investigate the physicochemical behaviour of IGI-based formulations found in historical Portuguese sources. Fresh and 6-month naturally aged precipitates and supernatant solutions (dried inks) were cha...

Polyoxometalate-Ionic Liquids for Mitigating the Effects of Iron Gall Ink Corro...
Nunes, Margarida; García-Orduña, Pilar; Atrián-Blasco, Elena; Costa Vieira, Joana; Costa, Ana Paula; Cabral Amaral, Maria Emília; Claro, AnaIron gall ink (IGI), renowned for its indelibility, was the most important writing ink in the Western world from the 15th to the late 19th century. However, it is now known that IGIs induce acid-catalyzed hydrolysis and iron-catalyzed oxidation of the cellulose in historical paper documents. These mechanisms of deterioration cause significant damage to the writing support materials, including color alteration a...
’Areia de escrever’ or ‘arena scriptoria’ in the materiality of writing: the in...
Olival, Fernanda; Nunes, Margarida; Wanzeller Martins, Gláucia; Ferreira, Teresa; Claro, Ana; Moita, PatríciaThe research conducted by this interdisciplinary team corroborates the existence of a distinct type of sand used for drying texts in Portugal during the 16th to 19th centuries. Although it shares similarities with materials found in other parts of Europe, these sands exhibit specific characteristics. Referred to as “writing sand”, it was frequently acquired by many convents and religious houses of that period. ...
A holistic approach to understanding the iron-gall inks in the historical docum...
Nunes, Margarida; Olival, Fernanda; Mitchell, Scott G.; Claro, Ana; Ferreira, TeresaA substantial part of our written heritage is threatened by the fact that much of it has been written using iron-gall ink (IGI). One such example is the documents of the Portuguese Inquisition Tribunals, held by the Arquivo Nacional da Torre do Tombo. Here we present the first systematic analytical approach, using SEM/EDS, µ-FT-IR-ATR and µ-Raman techniques, to characterise fragments from historical records of ...
’Litteras arena conspergere’. Uncovering blotting sands on the Portuguese Inqui...
Nunes, Margarida; Wanzeller Martins, Gláucia; Sarraguça, Jorge; Olival, Fernanda; Moita, Patrícia; Mitchell, Scott G.; Claro, Ana; Ferreira, TeresaHistorical and archival research focused on the Portuguese Inquisition documents (1551–1800) uncovered the use of arena known as blotting sands, a writing accessory used to hasten ink drying. We present in this work the first systematic study combining image analysis, SEM/EDS and µ-Raman techniques, statistics and chemometrics to characterise the blotting sands used by the Portuguese Inquisition and hypothesise...
