Cracking the code of hydrogen embrittlement      (via sciencedaily.com)     Original source 

When deciding what material to use for infrastructure projects, metals are often selected for their durability. However, if placed in a hydrogen-rich environment, like water, metals can become brittle and fail. Since the mid-19th century, this phenomenon, known as hydrogen embrittlement, has puzzled researchers with its unpredictable nature. Now, a study brings us a step closer to predicting it with confidence.
