FGSD: A Dataset for Fine-Grained Ship Detection in High Resolution Satellite Images [PDF]

open access: yesarXiv, 2020
Ship detection using high-resolution remote sensing images is an important task, which contribute to sea surface regulation. The complex background and special visual angle make ship detection relies in high quality datasets to a certain extent. However, there is few works on giving both precise classification and accurate location of ships in existing

Improved Chloride Tolerance of Pt Surface by Ionomer Layer Structure Engineering

open access: yesChemSusChem, EarlyView.
A hybrid ionomer interface combining cation and anion exchange ionomers effectively suppresses Cl− poisoning of Pt electrocatalysts. In situ inductively coupled plasma‐mass spectrometry measurements reveal a 40% reduction in local Cl− concentration on Pt, attributed to the surface charge distribution of the hybrid ionomer layers. This approach provides
