    How fast you cool molten iron determines its properties

    Summer201408, CC BY-SA 4.0, via Wikimedia Commons Cast iron, an alloy of iron with carbon, is widely used for making machine and automobile parts. In its liquid form, it flows easily, hence can be poured into moulds, offering intricate detailing in the part shape. It may be less ductile and malleable than wrought iron or less stiff than steel, but it has a lower melting point than other...

    Producing low-cost hydrogen fuel with the help of magnets

    Image by andreas160578 via Pixabay Hydrogen gas is an environment-friendly fuel, as it produces water upon combustion in the presence of oxygen. For the same weight, hydrogen can provide nearly three times higher energy than gasoline. However, the quantity of hydrogen available from the Earth's atmosphere is tiny. The more widely available compound, water, might be a source of...
