How Everything Is Made on Instagram: "Lithium-ion batteries start with two carefully engineered layers: a graphite anode and a lithium-metal-oxide cathode. Each material is mixed into a slurry, spread onto thin foil sheets, and dried until it forms a uniform coating. These sheets are then rolled, cut, and stacked with a porous separator that keeps them from touching while still allowing ions to move freely. Once the layers are assembled, the battery cell is tightly wound or stacked into its fina

Bio nano sensors part 20🥴The process of manufacturing graphene oxide nanofilms and their use as bio-nanosensors in an airborne setting involves several steps. Here's a detailed breakdown: ### Manufacturing Graphene Oxide Nanofilms 1. **Graphene Oxide Synthesis**: - **Hummers Method**: This is one of the most common methods for synthesizing graphene oxide. It involves the oxidation of graphite using strong oxidizing agents such as potassium permanganate (KMnO₄) and sulfuric acid (H₂SO₄). The pro
