Improving Magnesium Borohydride For Solid-state Hydrogen Storage

The key mechanism by which magnesium diboride (MgB2) absorbs hydrogen has been discovered by scientists at Lawrence Livermore National Laboratory (LLNL). The work, through theory and experimentation, also provides important insights into the reaction pathway that converts MgB2 to its highest hydrogen capacity form, magnesium borohydride (Mg(BH4)2). Mg(BH4)2 is a particularly promising hydrogen storage material because of its high hydrogen content and attractive thermodynamics. said Keith Ray, LLNL physicist and the paper’s lead author.

3 Well Water Chemicals Linked To Birth Defects

A new study links three contaminants, nitrates, atrazine, and arsenic, to birth defects, and cautions people who get their drinking water from private wells to consider having them tested. Just goes to show that water doesn’t have to smell or look wrong to be dangerous, especially to embryos in the first few weeks of development. Jean D. Brender, professor emeritus at the Texas A&M Health Science Center School of Public Health, said: [Read More]
