This article introduces a bimodal model based on the epsilon-skew-normal distribution. This extension generates bimodal distributions similar to those produced by the mixture of normal distributions. We study the basic properties of this new family. We apply maximum likelihood estimators, calculate the information matrix and present a simulation study to assess parameter recovery. Finally, we illustrate the results to three real data sets, suggesting this new distribution as a plausible alternative for modelling bimodal data.

This work is about the fabrication of composite thin films of nanoporous silicon/green synthesized silver nanoparticles and their potential use as antibacterial surfaces. To obtain the composite layers, silver nanoparticles were synthesized using leaf extracts of P. boldus, and subsequently integrated on nanoporous silicon matrix. The achieved samples were characterized microscopically (TEM and AFM), and physiochemically (UV–vis spectroscopy, LIBS, and XRD). Moreover, the antibacterial activity of the composite layers was studied using different strains of Gram-positive (S. aureus and S. epidermidis) and Gram-negative (K. pneumoniaeE. coli, and P. aeruginosa) bacteria. The experimental results showed the potential of these composite thin films as antibacterial surfaces for biomedical applications.
