Ferroelectricity in the xAg2Nb4O11–(1−x)Na2Nb4O11 solid solution

Compositions in the (AgxNa1-x)2Nb4O11 solid solution have been prepared by a conventional solid state method. Composites containing Ag2Nb4O11 have been shown to be ferroelectric and the Curie temperature shown to decrease from 149 °C at x = 1 to 62 °C at x = 0.7. Roomtemperature compositions with x ≤ 0.7 are monoclinic, while those with x ≥ 0.8 are rhombohedral with structures consistent with the relevant end-members. At x = 0.75, the structure was mainly rhombohedral but with coexistence of the monoclinic structure, indicating the proximity of a phase boundary

Editorial: Special issue: Colloquium on European Research in Retailing (CERR) 2014

This special issue presents the best papers from the second Colloquium on European Research in Retailing (CERR). CERR 2014 was held in September 2014 at the University of Bremen, Germany. The colloquium is the result of the collaboration of three European scientific research laboratories. Among those, the Department of Logistic Management of the University of Bremen was the main organising entity of CERR 2014. CERR’s aim is to offer researchers from all over Europe, on a bi-annual basis a meeting place to share in a congenial environment the result of their latest research dedicated to understanding consumers’ behavior and designing the operations, logistics, and channels to reach them. The other partners were the University of Surrey and ESSCA School of Management. The next research colloquium will be held in Toulouse in 2016
