(Phys.org) —A team of researchers from Tohoku University and Kyoto University in Japan has found a way to cause abnormal grain growth in metal crystals using cyclic heat treatment. In their paper published in the journal ...
New research predicts the criteria needed for Earth-like planets to form around a star that have one-tenth the metallicity of our Sun. If researchers find small, rocky planets orbiting stars with lower metallicity, it may ...
