A Monte Carlo code for the collisional evolution of porous aggregates (CPA)
Millan, Emmanuel N.; Planes, María Belén; Urbassek, Herbert M.; Bringa, Eduardo M. [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Chile] (EDP SCIENCES S A, 2023-03-29)Context. The collisional evolution of submillimeter-sized porous dust aggregates is important in many astrophysical fields.Aims. We have developed a Monte Carlo code to study the processes of collision between mass-asymmetric, ... -
Effect of the monomers ratio in the electrosynthesis of poly(aniline-co-o-methoxyaniline) on steel corrosion protection
Del Valle, M. A.; Mieres, E. [Univ Mayor, Fac Ciencias, Ingn Construcc, Chile]; Motheo, A.; Ramírez, A. M. R. [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Chile] (Sociedad Chilena de Química, 2020-12)In this work, the synthesis of poly(aniline-co-o-methoxyaniline) was carried out on AISI 304 steel, by voltammetric or potentiostatic method. Electropolymerization was achieved from different ratios of 0.4 mol.L-1 ... -
Erythroid Differentiation and Heme Biosynthesis Are Dependent on a Shift in the Balance of Mitochondrial Fusion and Fission Dynamics
Gonzalez-Ibanez, Alvaro M.; Ruíz, Lina M.; Jensen, Erik; Echeverria, Cesar A.; Romero, Valentina [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Chile]; Stiles, Linsey; Shirihai, Orian S.; Elorza, Alvaro A. (Frontiers Media S.A., 2020-11)Erythropoiesis is the most robust cellular differentiation and proliferation system, with a production of similar to 2 x 10(11) cells per day. In this fine-tuned process, the hematopoietic stem cells (HSCs) generate erythroid ... -
Magnon valley Hall effect in CrI3-based van der Waals heterostructures
Hidalgo-Sacoto, R.; Gonzalez, R., I [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Chile]; Vogel, E. E.; Allende, S.; Mella, José D.; Cárdenas, C.; Troncoso, Roberto E.; Muñoz, F. (American Physical Society, 2020-05)Magnonic excitations in the two-dimensional (2D) van der Waals (vdW) ferromagnet chromium triiodide (CrI3) are studied. We find that bulk magnons exhibit a nontrivial topological band structure without the need for ... -
Nanoindentation of polycrystalline Pd hollow nanoparticles: Grain size role
Pinto, Benjamin [Univ Mayor, Escuela Construcc, Chile]; Valencia, Felipe J. [Univ Mayor, Fac Estudios Interdisciplinarios, Ctr Invest DAiTA Lab, Chile]; Kiwi, Miguel; Ruestes, Carlos J.; Bringa, Eduardo M. [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Chile]; Rogan, José (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, ... -
Simulated mechanical properties of finite-size graphene nanoribbons
Aparicio, E.; Tangarife, E. [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Chile]; Muñoz, F.; Gonzalez, R., I [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Chile]; Valencia, F. J.; Careglio, C.; Bringa, E. M. [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Chile] (IOP Publishing Ltd., 2021-01)There are many simulation studies of mechanical properties of graphene nanoribbons (GNR), but there is a lack of agreement regarding elastic and plastic behavior. In this paper we aim to analyze mechanical properties of ... -
Spin-lattice-dynamics analysis of magnetic properties of iron under compression
dos Santos, Gonzalo; Meyer, Robert; Tramontina, Diego; Bringa, Eduardo M. [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Chile]; Urbassek, Herbert M. (NATURE PORTFOLIO, 2023-08-31)Compression of a magnetic material leads to a change in its magnetic properties. We examine this effect using spin-lattice dynamics for the special case of bcc-Fe, using both single- and poly-crystalline Fe and a bicontinuous ... -
Structural Relaxation and Crystalline Phase Effects on the Exchange Bias Phenomenon in FeF2/Fe Core/Shell Nanoparticles
Velásquez, Ever A.; Mazo-Zuluaga, Johan; Tangarife, Edwin [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Chile]; Mejia-López, José (John Wiley and Sons Ltd, 2020-09)In this study, the power of first-principles methods along with molecular dynamics and atomistic Monte Carlo simulations is employed to elucidate the effects of the structural relaxation on the exchange bias (EB) behavior ...
