Modelling Digital Avatars: a tuple space approach
(2021-01-07)The development of the Internet of Things (IoT) came with the manufacturing of a huge amount of smart things equipped with sensors for making them aware of their environment, and with network connection for allowing remote ... -
NH3/H2O-mediated proton conductivity and photocatalytic behaviour of Fe(II)-hydroxyphosphonoacetate and M(II)-substituted derivatives
(The Royal Society of Chemistry, 2019-12-27)Synthesis redesign and derivatisation of Fe(II)-hydroxyphosphonoacetate, incorporating different ammonia loads and M(II) isomorphic substitutions (M = Mn, Co and Zn), have been implemented. The NH3 adsorption led to materials ... -
Phase Transformation Dynamics in Sulfate-Loaded Lanthanide Triphosphonates. Proton Conductivity and Application as Fillers in PEMFCs
(ACS Publications. American Chemical Society, 2021)Phase transformation dynamics and proton conduction properties are reported for cationic layer-featured coordination polymers derived from the combination of lanthanide ions (Ln3+) with nitrilo-tris(methylenephosphonic ... -
Phase-selective degree of hydration at setting: An in situ synchrotron diffraction study
(Elsevier, 2022-03)Setting of Portland cements is still not well understood. Previous studies used techniques that analyse the pastes as a whole to correlate setting times with degree of hydration. Here, in-situ synchrotron X-ray diffraction ... -
Preservice Elementary Science Teachers' Argumentation Competence: Impact of a Training Programme
(Springer, 2018)The recent literature has shown the importance of Preservice Elementary Science Teachers (PESTs) having a deep understanding of argumentation, as this factor may affect the nature of the class activities that are taught ... -
Relationships and tensions between the curricular program and the lived curriculum. A narrative research
(Teaching and Teacher Education, 2021)This research focused on the relationships that teachers and students establish with curricular programs, the tensions they experience, and the effects this has on shaping the classroom experience. The study employed a ... -
Resilient Bioinspired Algorithms: A Computer System Design Perspective
(SpringerLink, 2022)Resilience can be defined as a system's capability for returning to normal operation after having suffered a disruption. This notion is of the foremost interest in many areas, in particular engineering. We argue in this ... -
Sequential extraction procedure: a versatile tool for environmental research
(CISA publisher, 2020-12-28)The sequential extraction procedure as a tool to assess the environmental risk of metals in solid matrices has been widely studied. In this work, other promising application of these methods is proposed: the evaluation of ... -
Synthesis, characterization and biological evaluation of octyltrimethylammonium tetrathiotungstate
(Springer Nature, 2021)Octyltrimethylammonium tetrathiotungstate salt (ATT-C8) was synthesized and its ability to chelate copper was evaluated. The biological and toxic aspects were evaluated by in vitro and in vivo assays, using bovine aorta ... -
The influence of sock composition on the appearance of foot blisters in hikers
(Elsevier, 2022-02-04)Introduction: Socks are of fundamental importance in reducing friction and in controlling the temperature and humidity of the foot, thus preventing the appearance of blisters. However, the influence of sock fibres ... -
The role of sodium and sulfate sources on the rheology and hydration of C3A polymorphs
(Elsevier, 2022)The higher reactivity of orthorhombic C3A (ort-C3A) in sulfate-containing solutions, compared with cubic C3A (cb-C3A), was previously related to the differences in crystal structure or the sodium in the ort-C3A pore solution. ... -
Zinc(II), cobalt(II) and manganese(II) networks with phosphoserine ligand: Synthesis, crystal structures magnetic and conduction properties
(The Royal Society of Chemistry, 2017)A series of zinc(II), cobalt(II) and manganese(II) coordination networks with the phosphoserine ligand (Pser) is synthesized and characterized. Whereas in compounds 1 and 2 with the general formula [M(Pser)]n [M = Zn (1) ...
