Tech and Inovation by DOC on Instagram: "The NamX HUV packs six hydrogen fuel cells and delivers up to 1,500 km of range — a glimpse at what the future looks like beyond batteries. Instead of long charging times, this SUV swaps hydrogen capsules in minutes, turning refueling into a system as fast as filling petrol. Zero emissions. Massive range. And a modular fuel design that could rewrite how we power long-distance travel. It’s not just a concept car it’s a challenge to EV limits and a roadmap

World of biology on Instagram: "When hydrogen peroxide (H2O2) and potassium permanganate (KMnO4) react, they undergo a redox reaction, resulting in the formation of oxygen gas (O2), water (H2O), and manganese dioxide (MnO2). The reaction is exothermic, meaning it releases heat. Potassium permanganate acts as a catalyst, speeding up the decomposition of hydrogen peroxide into oxygen and water."
