Cyclic Calcium Phosphate Electrodeposition on Porous Silicon
International Journal of Electrochemical Science, 2012 Calcium phosphate (CaP) on porous silicon (PSi) has been proposed to generate composite bioceramics for osseous tissue regeneration. Usually, CaPs prepared by biomimetic and electrochemical methods stem from a single aqueous solution. We propose herein a

Coupling Patterns of External Arguments in the Multiple-Spiral Medallions of the Mandelbrot Set
Discrete Dynamics in Nature and Society, 2009 The multiple-spiral medallions are beautiful decorations situated in the proximity of the small copies of the Mandelbrot set. They are composed by an infinity of babies Mandelbrot sets that have external arguments with known structure.

Experimental estimation of the longitudinal component of a highly focused electromagnetic field
Scientific Reports, 2021 The detection of the longitudinal component of a highly focused electromagnetic beam is not a simple task. Although in recent years several methods have been reported in the literature, this measure is still not routinely performed.

Effect of Zinc Oxide Nanoparticles From Infant Formula Milk Powder on Colon Cells In Vitro
Journal of Applied Toxicology, EarlyView.ABSTRACT Zinc is an essential trace element that participates in numerous metabolic processes; however, excessive exposure may interfere with the absorption of other metals, such as copper. In recent years, nanotechnology has experienced rapid growth, and zinc oxide nanoparticles (ZnO NPs) have garnered significant attention due to their versatile ...

frontiermetrics: An R Package for Characterizing Deforestation Frontiers
Remote Sensing in Ecology and Conservation, EarlyView.Deforestation frontiers are major drivers of biodiversity loss, carbon emissions, and ecosystem degradation, yet our understanding of how deforestation progresses in these frontiers is limited. We present frontiermetrics, an R package to quantify a range of metrics describing the speed, severity, and spatio‐temporal patterns of forest loss. The package

Adaptation of an empirical model for erythemal ultraviolet irradiance [PDF]
Annales Geophysicae, 2007 In this work we adapt an empirical model to estimate ultraviolet erythemal irradiance (UVER) using experimental measurements carried out at seven stations in Spain during four years (2000–2003).
