New Poly(imide)s Bearing Alkyl Side-Chains: A Study on the Impact of Size and Shape of Lateral Groups on Thermal, Mechanical, and Gas Transport Properties
Rodríguez-González, Fidel E.; Pérez, Germán; Niebla, Vladimir; Jessop, Ignacio; Martin-Trasanco, Rudy; Ortiz, Pablo A. [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Chile]; Coll, Deysma [Univ Mayor, Fac Estudios Interdisciplinarios, Nucleo Quim & Bioquim, Chile]; Aguilar-Vega, Manuel; Tagle, Luis H.; Terraza, Claudio A.; Tundidor-Camba, Alain (MDPI AG, 2020-07)A set of five new aromatic poly(imide)s (PIs) incorporating pendant acyclic alkyl moieties were synthesized. The difference among them was the length and bulkiness of the pendant group, which comprises of linear alkyl ... -
Optical, morphological and photocatalytic properties of biobased tractable films of chitosan/donor-acceptor polymer blends
Jessop, I.; Albornoz, J.; Ramírez, O.; Durán, B.; Molero, L.; Bonardd, S. [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Chile]; Kortaberria, G.; Díaz Díaz, D.; Leiva, A.; Saldias, C. (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, ... -
Physicochemical properties of L-alpha dipalmitoyl phosphatidylcholine large unilamellar vesicles: Effect of hydrophobic block (PLA/PCL) of amphipathic diblock copolymers
Flandez, Karina; Bonardd, Sebastian [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Chile]; Soto-Arriaza, Marco (Elsevier Ireland Ltd, 2020-08)In the present work, we show how amphipathic diblock copolymers affect the physicochemical properties of the lipid bilayer of DPPC liposome. Diblock copolymers proposed for this study are focused in the difference between ... -
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 of surface vs core magnetization in Fe nanoparticles
dos Santos, Gonzalo; Meyer, Robert; Aparicio, Romina; Tranchida, Julien; Bringa, Eduardo M. [Univ Mayor, Fac Ciencias, Ctr Nanotecnol Aplicada, Chile]; Urbassek, Herbert M. (AIP Publishing, 2021-07-05)Magnetization of clusters is often simulated using atomistic spin dynamics for a fixed lattice. Coupled spin-lattice dynamics simulations of the magnetization of nanoparticles have, to date, neglected the change in the ... -
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 ... -
