MeV irradiation of tungsten nanowires: structural modifications
(IOP Publishing Ltd., 2020-05)
In this work we use the Two Temperature Model coupled to Molecular Dynamics (TTM-MD) to study swift heavy ion irradiation of W finite nanowires. Au projectiles are considered with energies ranging from 20 to 50 MeV, which ...
Nanoindentation of polycrystalline Pd hollow nanoparticles: Grain size role
(Elsevier, 2020-06)
Polycrystalline hollow nanoparticles present a unique combination of strength and flexibility. However, the exact role displayed by their grain structure in mechanical properties has not been yet fully understood. Here, ...
Modeling habitat suitability and spread dynamics of two invasive rose species in protected areas of Mendoza, Argentina
(Elsevier, 2020-12)
Biological invasions are a main threat to biodiversity and natural resources, which calls for studies that identify the regions that present the greatest invasion risks. We assessed the potential distribution of two ...
Molecular dynamics simulations of thermal conductivity between two nanoparticles in contact
(American Institute of Physics, 2020-06)
The nanoscale properties of materials can have a great influence on their macroscopic behavior; for instance, the generation and accumulation of defects at the nanoscale, such as point defects, porosity, and interfaces, ...
Collisions between amorphous carbon nanoparticles: phase transformations
(EDP Sciences, 2020-09)
Context. Collisions of nanoparticles (NPs) occur in dust clouds and protoplanetary disks.Aims. Sticking collisions lead to the growth of NPs, in contrast to bouncing or even fragmentation events and we aim to explore these ...
Optical, morphological and photocatalytic properties of biobased tractable films of chitosan/donor-acceptor polymer blends
(Elsevier Ltd., 2020-12)
Biobased tractable films consisting of blends of chitosan (CS) with polymer bearing carbazole derivatives as pendant groups and fluorene-thiophene as donor-acceptor units (referred to as DA) were prepared, and their optical, ...
Increasing the temperature range of dipolar glass polymers through copolymerization: A first approach to dipolar glass copolymers
(Elsevier BV, 2020-08)
This work introduces, for the first time, the dipolar glass copolymer concept as a new strategy to develop polymer dielectrics. Methacrylic monomers containing sulfone and nitrile groups were copolymerized with ...
Doped Poly(3-hexylthiophene) Coatings onto Chitosan: A Novel Approach for Developing a Bio-Based Flexible Electronic
(American Chemical Society, 2020-03)
Conductive and flexible bio-based materials consisting of chitosan films coated with conductive poly(3-hexylthiophene) (P3HT) were prepared. Thermal, optical, mechanical, morphological, wettability, and conductive properties ...
Effect of Tip Roundness on the Nanoindentation of Fe Crystals
(Springer New York, 2020-04)
Indentation tips are never atomically sharp, but rounded at their end. We use atomistic simulation to study the effect of tip roundness for the particular case of a cube-corner pyramidal indenter by comparing the results ...
Effect of subsurface voids on the nanoindentation of Fe crystals
(IOP Publishing Ltd., 2020-03)
Subsurface voids may strongly affect the response of materials to nanoindentation. We explore these effects for a bcc single-crystalline Fe sample using molecular dynamics simulation. Deformation occurs mainly by nucleation ...
