The erosion of East Antarctica is mainly due to the glacial phase at the end of the Primary Era

Published on January 23, 2019

A team involving researchers from six French laboratories, including the Institute of Earth Sciences, has been reconstructing the history of East Antarctica’s erosion for 350 million years (Ma). This study shows that Antarctic erosion is essentially very old, dating back to the Late Paleozoic Ice Age (LPIA), a major glaciation period dated 340-300 Ma. The relief is essentially inherited from this period, while the Antarctic ice cap has had little impact on erosion over the last 30 Ma. (…)

Tracing titanium dioxide nanoparticles in the environment

Published on January 21, 2019

The abundance of titanium dioxide nanoparticles in the environment originating from human activities could be a potential environmental problem. To identify and distinguish between titanium dioxide nanoparticles from natural and anthropogenic sources, synchrotron techniques were used to study the nanoparticles in sewage sludge and soil.
Titanium dioxide nanoparticles are one of the most commonly produced nanomaterials worldwide. They are present in many consumer products, such as (…)
