Dynamic behavior of the glassy and supercooled liquid states of Aceclofenac ass...
Viciosa, M. Teresa; Ramos, Joaquim J. Moura; Garcia, Ana; Diogo, Hermínio P.Aceclofenac (ACF), a non-steroidal anti-inflammatory drug, was obtained in its amorphous state by cooling from melt. The glass transition was investigated using dielectric and calorimetric techniques, namely, dielectric relaxation spectroscopy (DRS), thermally stimulated depolarization currents (TSDC), and conventional and temperaturemodulated differential scanning calorimetry (DSC and TM-DSC). The dynamic beha...
Development of a dry powder insufflation device with application in in vitro ce...
Pontes, Jorge Filipe; Diogo, Hermínio P.; Conceição, Eusébio; Almeida, Maria P.; Borges dos Santos, Rui M.; Grenha, AnaResearch on pharmaceutical dry powders has been increasing worldwide, along with increased therapeutic strategies for an application through the pulmonary or the nasal routes. In vitro methodologies and tests that mimic the respiratory environment and the process of inhalation itself are, thus, essential. The literature frequently reports cell-based in vitro assays that involve testing the dry powders in suspen...
Thermophysical properties of n-alkane system for low temperature thermal energy...
Nogueira, Bernardo A.; Nikitin, Timur; Diogo, Hermínio P.; Fausto, Rui; Fareleira, João; Caetano, Fernando J. P.; Sequeira, Maria CarolinaOver the past few decades, the escalating need for energy has posed a significant and pressing challenge. For centuries, fossil fuels stood as the dominant energy source; however, due to their dwindling availability and environmental complications, renewable energies have emerged as the promising solution for the future [1]. The intermittent nature of renewable energy sources often results in a disconnect betwe...
Solid–liquid phase equilibrium: alkane systems for low-temperature energy storage
Diogo, Hermínio P.; Fausto , Rui; Sequeira, Maria Carolina; Fernando J. P. Caetano; Fareleira, João M. N. A.; Nogueira, Bernardo A.The thermal characterization of two binary systems of n-alkanes that can be used as Phase Change Materials (PCMs) for thermal energy storage at low temperatures is reported in this work. The construction of the solid–liquid binary phase diagrams was achieved using differential scanning calorimetry (DSC) and Raman spectroscopy. The solidus and liquidus equilibrium temperatures were determined using DSC for thirt...

Dynamic spin interchange in a tridentate Fe(iii) Schiff-base compound
Vicente, Ana I.; Joseph, Abhinav; Ferreira, Liliana P.; Carvalho, Maria de Deus; Rodrigues, Vítor H. N.; Duttine, Mathieu; Diogo, Hermínio P.The thermosalient effect is still a rare and poorly understood phenomenon, where crystals suddenly jump, bend, twist or explode upon undergoing a thermally activated phase transition. The synthesis and characterisation of the new spin transition Fe(iii) compound [Fe(5-Br-salEen)2][ClO4] (salEen = N-ethyl-N-(2-aminoethyl)salicylaldiminate) is described and its thermosalient behaviour reported. It is the first ex...
