Morphological and histometric features of the caudal kidney in piranha Pygocentrus nattereri (Characiformes: Serrasalmidae)

Neotropical Ichthyology, 2023
Pygocentrus nattereri is a widely distributed species in the Neotropical region and a potential bio-indicator. Kidneys have functions in fish physiology, allowing them to live in different environments.

Relevant Aspects of Piranha Passivation in Ti6Al4V Alloy Dental Meshes

Coatings, 2022
Passivation of titanium alloy dental meshes cleans their surface and forms a thin layer of protective oxide (TiO2) on the surface of the material to improve resistance to corrosion and prevent release of ions to the physiological environment.

Use of Piranha Solution as An Alternative Route to Promote Bioactivation of PEEK Surface with Low Functionalization Times

Molecules, 2022
This study aimed to achieve bioactivity on the PEEK surface using piranha solution through a lower functionalization time. For this purpose, the functionalization occurred with piranha solution and 98% sulfuric acid in the proportions of 1:2, 1:1, and 2 ...

Biomass Waste Carbonization in Piranha Solution: A Route to Hypergolic Carbons?

Micro, 2022
In the present work we report for the first time the carbonization of biomass waste, such as stale bread and spent coffee, in piranha solution (H2SO4-H2O2) at ambient conditions.

Tango with the Piranhas [PDF]

Matter, 2020
Coexisting with fish known by their fiercely predaceous behaviors has driven the Arapaimas gigas to develop one of the toughest protective layers known in nature, their elasmoid scales. In this work, Yang et al. demonstrated what mechanisms lead to such remarkable toughness.
