In-Silico Design, Synthesis and Evaluation of a Nanostructured Hydrogel as a Dimethoate Removal Agent
(Chile. Universidad Mayor, 2018-01-04)This study describes the in-silico design, synthesis, and evaluation of a cross-linked PVA hydrogel (CLPH) for the absorption of organophosphorus pesticide dimethoate from aqueous solutions. The crosslinking effectiveness ... -
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 ... -
Indentation and scratching of iron by a rotating tool-a molecular dynamics study
(ELSEVIER, 2021-06-15)When abrasive particles interact with a surface, besides translational center-of-mass motion also rotational motion of the abrasive may be involved. We perform molecular dynamics simulations of the influence of the rotational ... -
Inducing Porosity on Hollow Nanoparticles by Hypervelocity Impacts
