Marine lubricating oil (LO) is deteriorated by contaminants—especially marine gas oil (MGO), which is invariably mixed during its usage—that can damage engine performance. This study investigates a method for determining the content of MGO in lub

In this work, cobalt/cobalt oxide (Co-CoOx) core-shell nanoflakes were directly grown on flexible graphite felt (GF) using a facile one-step intense pulsed white light (IPWL) irradiation method. They were then used as a battery-type positive electrod
