Model of dissolution in the framework of tissue engineering and drug delivery
(Springer, 2018-10)
Dissolution phenomena are ubiquitously present in biomaterials in many different fields. Despite the advantages of simulation-based design of biomaterials in medical applications, additional efforts are needed to derive ...

PEGylated Terbium-Based Nanorods as Multimodal Bioimaging Contrast Agents
(American Chemical Society, 2021)
Diagnostic imaging strongly relies on the use of contrast agents (CAs). In general terms, current CAs present undesirable side effects that encourage researchers and pharmaceutical companies to continually search for safer ...

A simple and economical device to process Ti cylinders with elongated porosity by freeze-casting techniques: design and manufacturing [Póster]
(Trans Tech Publications Ltd., 2017)
Design, manufacture and validation of a simple and economic device that allows producing Ti cylinders with directed porosity applying the freeze-casting technique, and the study of the influence on the internal structure ...

Physical proximity of chromatin to nuclear pores prevents harmful R loop accumulation contributing to maintain genome stability
(National Academy of Sciences, 2017)
During transcription, the mRNA may hybridize with DNA, forming an R loop, which can be physiological or pathological, constituting in this case a source of genomic instability. To understand the mechanism by which eukaryotic ...

Crystallization Process and Microstructural Evolution of Melt Spun Al-RE-Ni-(Cu) Ribbons
(MDPI, 2020-03)
The crystallization process, both at the initial and subsequent stages, of amorphous Al88-RE4-Ni8 alloys (RE = Y, Sm and Ce) has been studied. Additionally, the consequences of adding 1 at.% Cu replacing Ni or Al were ...

Consolidation by MF-ERS of mechanically alloyed Al powder
(Elsevier, 2019-07)
The aim of this work is to study the viability of producing, by medium-frequency electrical resistance sintering (MF-ERS), compacts from mechanically alloyed aluminium powders. The MF-ERS process was carried out using ...

Synthesis, characterization and performance of robust poison-resistant ultrathin film yttria stabilized zirconia – nickel anodes for application in solid electrolyte fuel cells
(Elsevier, 2016)
We report on the synthesis of undoped ∼5 μm YSZ-Ni porous thin films prepared by reactive pulsed DC magnetron sputtering at an oblique angle of incidence. Pre-calcination of the amorphous unmodified precursor layers followed ...

Crystallisation of amorphous Al-Y-Ni-(Cu)alloys
(Elsevier, 2019)
The nanocrystallisation behaviour and subsequent intermetallics formation of an amorphous Al88-Y4-Ni8 alloy has been studied. A 1 at% of Al or Ni was also substituted by Cu and its effect studied. Differential scanning ...

In Situ Synthesis of Al-Based MMCs Reinforced with AlN by Mechanical Alloying under NH3 Gas
(MDPI, 2018)
Aluminum matrix composites (AMCs) reinforced by aluminum nitride were prepared by mechanical alloying followed by a simple press and sintering method. Milling began under vacuum and after a period of between 1 and 4 h, ...

Medium-frequency electrical resistance sintering of oxidized C.P. iron powder
(MDPI, 2018)
Commercially pure (C.P.) iron powders with a deliberate high degree of oxidation were consolidated by medium-frequency electrical resistance sintering (MF-ERS). This is a consolidation technique where pressure, and heat ...
