A research team has shown that methanogens, micro-organisms ubiquitous in low-oxygen environments like aquifers, soil and even permafrost, can propel their growth by dissolving calcium carbonate, one ...

We discuss the limiting regimes of completely coherent tunneling and completely incoherent transmission, and discuss the continuous transition between the two. Over a wide range of inelastic ...

Experiments on battery electrodes and fuel cell catalysts while they're being used - operando spectroscopy - can ...
