Creative destruction—the process by which innovation replaces outdated businesses and production methods—propels the economy toward the technological frontier. Impediments to this process can hinder productivity growth and economic development. Specifically, barriers to firms exiting the market, such as the costs of bankruptcy, laying off workers, and selling or repurposing assets, can stifle firm creation and weaken an economy.

Study on mechanisms of two-step hydrogen sorption in MgH2-TiCrMnFeZr high-entropy alloy composite High-entropy alloys (HEAs) featuring with multi-element active sites show exclusive catalytic ability, as well as great potential to store hydrogen (H2) at room temperature by adjusting the electronic and geometrical factors. Herein, a TiCrMnFeZr HEA was adopted to improve the hydrogen storage properties of magnesium hydride (MgH2).
