Nuvola Portuguese flag.svg These are the finalists for WSC2019 in Portugal.

This country-level selection had a specific national organizer and a national coordination page.


  • This country has a category for its files, other files from there might have been uploaded after the local deadline and moved to the 2019 international category if such deadline was still valid.
  • As of now, the files in the local category uploaded within the local deadline are 75, with 5 obviously unsuitable files.
  • Uploaders statistics are available here.

Specific classes of files[edit]


  • the selection was performed directly, with no tool.
  • coordinator: Gonçalo Themudo.

The spectacular human interaction with science. Plasma ball at Pavilion of knowledge, Lisbon.
This common blackbird (Turdus merula) was captured during a bird ringing session in Lagoa da Salgueirinha (Paredes de Coura, Portugal), in May 2019. After taking biometric measurements and ringing the bird, it was released.

Microscopy images[edit]

1st national finalist 2nd national finalist
Crystallisation of hydroxyapatite (HAp) nanoparticles on Si-Ca-Na-P bioglass after immersion in simulated body fluid. In this case, HAp has formed as a pear-shaped microcrystal (~5 microns high), which even appears to have a bite taken out of it. By comparison, a human hair is ~100 microns thick. The bioglass was made by our novel rapid (200 times faster) sol-gel process. HAp is the main component of human bone. This bioglass can be used in biomedicine to make scaffolds or bio-implants to replace/regenerate damaged bone. (False colour, as this is an SEM image)

This is a cork-based biomimetic ("copying nature") ecoceramic ("Environmentally Conscious Ceramic") made of ceria (CeO2). This is a pure ceramic, but with the hexagonal microstructure of the cork template, which is very porous and made of regular hexagonal cells ~20 microns in diameter (by comparison, a human hair is ~100 microns diameter). Cork is a sustainable material, as the bark is harvested without damaging the tree, which lives on as a carbon sink for over 200 years. The cork is then converted into the ceria ecoceramic. The image shows, from right to left, the ceria ecoceramic made of hexagonal cells, a single hexagonal cell, and the tiny ceria nanoparticles of which the ecoceramic is actually formed, with scale bars in each image. We are using this to split water to make renewable hydrogen fuel with concentrated solar energy via a solar thermochemical process.

Image sets[edit]

Photos taken with a Huawei Mate 10 lite cell phone camera through the eyepiece of a Leica MZ 12 stereoscopic microscope. It represents the geometric morphology of the crystalization of this cubic system mineral. The rigorous orientations of several overlayed layers and of the crystalization images determine the physical properties that provide the cutting surfaces that the cutter will have to choose.

The blue tit (Cyanistes caeruleus) was caught in a bird banding session and, after banding the bird and taking some biometric measurements it was released. The session occurred at Parque Biológico de Gaia.

General category[edit]

1st national finalist
Franz difusion cells in this photo: ertical Franz diffusion cells of static flow on glass, are a largely used system in "in vitro" evaluation studies of stress and permeation, to determine the cinetic profile of the analyzed substance, in this case caffeine. Photo taken during a class in Tecnologia Farmacêutica II at the Faculty of Pharmacy of the University of Lisbon.

Wildlife and Nature[edit]

This Perez's frog was photograped at Porto's Botanical Garden. Due to its ability to remain hidden in the surrounding environment, it may go unnoticed to less watchfull visitors.

An Old world swallowtail (Papilio machaon) on a rock. Its colours are similar to those of the lichen on the rock.
