but would behave much like certain elements at ordinary temperatures. The periodic law would enable physicists to predict almost with certainty which elements would exhibit the desired effect best ...

IT has been shown by one of us 1 that, at ordinary temperatures, the structure of nickel oxide is slightly deformed from face-centred cubic symmetry. Later work 2 proved that at − 180° C.

In a two-step process, a new catalyst can convert methane into polymers at ordinary temperature and pressure. Although it is less abundant than carbon dioxide, methane gas contributes ...

Note: Temperature anomalies compared to the average between 1951-1980. An “anomaly” is the difference between the estimated average ocean and atmospheric temperature in any given month and the ...
