Michael Stanley Whittingham

The winner of Nobel Prize in Chemistry.

The winner of Nobel Prize in Chemistry, Michael Stanley Whittingham explained the importance of XRD in identification of phases during his talk at ICDD in 2021 regarding the importance of batteries for clean energy, and development of new technologies. He and his team discovered that holding lithium ions between plates of titanium sulfide created electricity. The lightweight lithium-ion batteries power laptops, tablets, cellphones and most electric cars. They have laid the foundation for a wireless, fossil fuel-free society.

Hydrogen storage is a critical aspect of developing hydrogen as a clean energy source and it plays a vital role in developing hydrogen as a versatile and sustainable energy carrier. In Solid-State Hydrogen Storage, Hydrogen is absorbed into or adsorbed onto solid materials like metal hydrides, carbon-based materials, or complex hydrides. This method can be safer and more compact than gas or liquid storage but may have issues with weight and the efficiency of hydrogen release and absorption. Several methods exist for storing hydrogen. These include mechanical approaches such as using high pressures and low temperatures, or employing chemical compounds that release H2 upon demand. While large amounts of hydrogen are produced by various industries, it is mostly consumed at the site of production, notably for the synthesis of ammonia. For many years hydrogen has been stored as compressed gas or cryogenic liquid, and transported as such in cylinders, tubes, and cryogenic tanks for use in industry or as propellant in space programs. Although molecular hydrogen has very high energy density on a mass basis, partly because of its low molecular weight, as a gas at ambient conditions it has very low energy density by volume. If it is to be used as fuel stored on board a vehicle, pure hydrogen gas must be stored in an energy-dense form to provide sufficient driving range. Because hydrogen is the smallest molecule, it easily escapes from containers. Materials like this one, capable of storing hydrogen through solid-gas interactions or electrochemical methods, present new opportunities for energy storage.

How To Make Pr2Mg2Co9 Alloy

To make Pr2Mg2Co9 alloy, the scientist used very pure ingots of Pr and Co, along with Mg powder.

This block was then ground into a fine powder and mixed with Mg powder.

Next

The mixture was pressed into pellets, wrapped in foil, placed in a sealed stainless-steel container, and heated gradually to 1073K.

Next

After heating, the alloys were slowly cooled down to 773 K, kept at this temperature for about 250 hours, and then quickly cooled in cold water.

Next

Finally, they used X-ray diffraction to analyze the structure of the alloys.

First, they melted Pr and Co together in an argon atmosphere to form a solid block.
