Beschreibungen/Notizen

• Robert Cahnin News and Views discusses work by Sleight's group demonstrating that the phase ZrW2O8 has a negative thermal expansion. But the conclusion is not novel: this phase is one of many known for decades to exhibit the phenomenon. (Three relevant reviews were not cited in the News and Views article.) Further, Sleight's group and Cahn both fail to note the discovery of the very significant, incredibly large NZP-CTP (NaZr2P3O12or Ca0.5Ti2P3O12) structural family first found by us, subsequently studied by many groups and now commercialized. (Individual references to other relevant publications can be found in refs 4-6. A bibliography containing 100 articles on the NZP family, including references to the examples mentioned below, is available on request from the authors.)
