Microstructural Evolution Characterization of Fe-Nb-B Ternary Systems Processed by Ball Milling
(Taylor & Francis, 2009)
Fe-Nb-B alloys prepared by ball milling can undergo a complex microstructural evolution during milling. In order to overcome the limitations imposed by traditional X-ray bulk analysis, a comprehensive multi-technique ...

Active spheres induce Marangoni flows that drive collective dynamics
(Springer, 2021)
For monolayers of chemically active particles at a fluid interface, collective dynamics is predicted to arise owing to activity-induced Marangoni flow even if the particles are not self-propelled. Here, we test this ...

Preferential Co Partitioning to α-Fe in Nanocrystalline CoFeNbB Alloys by Mn Addition
(Elsevier, 2009)
Influence of Mn addition on the microstructure and hyperfine parameters of amorphous and nanocrystalline Co60(FeMn)18Nb6B16 alloys has been studied. Although Mn addition does not yield significant differences in crystallization ...

Nucleus-translocated mitochondrial cytochrome c liberates nucleophosmin-sequestered ARF tumor suppressor by changing nucleolar liquid-liquid phase separation.
(Nature Research, 2022-10-11)
The regular functioning of the nucleolus and nucleus-mitochondria crosstalk are considered unrelated processes, yet cytochrome c (Cc) migrates to the nucleus and even the nucleolus under stress conditions. Nucleolar ...

Thermal and Microstructural Stability of the Soft Magnetic Fe60Co18Nb6B15Cu1 alloy
(Elsevier, 2007)
Temperature evolution of the coercivity of nanocrystalline samples of Fe60Co18Nb6B15Cu1 alloy with different crystalline fractions was measured from room temperature up to 690 K. Although room temperature coercivity increases ...

High Temperature Coercivity of Nb-containing HITPERM Alloys: Effect of Cu Addition
(Elsevier, 2008)
Hysteresis loops of nanocrystalline samples of Fe39Co39Nb6B16 - yCuy (y = 0, 1) HITPERM-type alloys were measured from room temperature up to 773K. The alloy with Cu shows a nearly constant value of coercivity (∼ 135A/m) ...

Performance and limits of a shallow-water model for landslide-generated tsunamis: from laboratory experiments to simulations of flank collapses at Montagne Pelée (Martinique)
(Oxford University Press, 2023-05)
We investigate the dynamics and deposits of granular flows and the amplitude of landslide-generated water waves using the HySEA depth-averaged shallow-water numerical model, both at laboratory and field scales. We evaluate ...

Heteroatom framework distribution and layer charge of sodium Taeniolite
(Elsevier, 2018)
The most advanced applications of clays depend crucially on their hydration state and swelling is probably the most important feature of expandable 2:1 layered silicate. Sodium Taeniolite, Na-TAE, a swelling trioctahedr ...

Self-Motility of an Active Particle Induced by Correlations in the Surrounding Solution
(American Physical Society, 2020)
Current models of phoretic transport rely on molecular forces creating a “diffuse” particle-fluid interface. We investigate theoretically an alternative mechanism, in which a diffuse interface emerges solely due to a ...
