Phase transitions in amorphous calcium phosphates with different Ca/P ratios

Autor: Alfons Baiker, Stefan Loher, Marek Maciejewski, Wendelin J. Stark, Tobias J. Brunner

Publikováno v: Thermochimica Acta. 468:75-80

The phase transitions occurring during calcination of flame-made calcium phosphates with Ca/P ratios between 1.00 and 1.54 were investigated by thermal analysis and powder X-ray diffraction from room temperature to 1350 °C. The as-prepared samples w

Publikováno v: Langmuir. 23:3473-3477

Porous metal films for optical humidity sensing were prepared from copper nanoparticles protected by a 2-3 nm carbon coating, a silicon tenside, and a polymeric wetting agent. Exposure to water or solvent vapor revealed an exceptional sensitivity wit
