High temperature behavior of nanostructured Al powders obtained by mechanical alloying under NH3 flow
(American Institute of Physics Inc., 2015-03)
Aluminium powder was mechanically alloyed under ammonia gas flow for different times (1-5 h) in order to produce a second-phase reinforcement, mainly by aluminium nitride (AlN). After milling, powders were consolidated ...

Influence of the Compaction Pressure and Sintering Temperature on the Mechanical Properties of Porous Titanium for Biomedical Applications
(MDPI, 2019)
In the present work, the use of porous titanium is proposed as a solution to the difference in stiffness between the implant and bone tissue, avoiding the bone resorption. Conventional powder metallurgical technique is an ...

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 ...

Inferring origin–destination trip matrices from aggregate volumes on groups of links: a case study using volumes inferred from mobile phone data
(John Wiley & Sons, Ltd., 2013)
The origin–destination matrix is an important source of information describing transport demand in a region. Most commonly used methods for matrix estimation use link volumes collected on a subset of links in order to ...

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 ...

Nature of the "Z"-phase in layered Na-ion battery cathodes
(Royal Society of Chemistry, 2019-05-17)
Layered sodium transition metal oxides with the P2 structure, e.g. Na2/3[Ni1/3Mn2/3]O2, are regarded as candidates for Na-ion battery cathodes. On charging, extraction of Na destabilizes the P2 phase (ABBA oxide ion stacking) ...
