Structural transition and amorphization in compressedα−Sb2O3

Pressure-induced structural evolution and amorphization in Eu3Ga5O12

Stabilization of scandium terephthalate MOFs against reversible amorphization and structural phase transition by guest uptake at extreme pressure.

Previous high-pressure experiments have shown that pressure-transmitting fluids composed of small molecules can be forced inside the pores of metal organic framework materials, where they can cause phase transitions and amorphization and can even induce porosity in conventionally nonporous materials. Here we report a combined high-pressure diffraction and computational study of the structural r...

Ion-beam-induced amorphization and order-disorder transition in the murataite structure

Murataite sA3B6C2O22−x/2 ,F4̄3md, a derivative of an anion-deficient fluorite structure, has been synthesized as different polytypes as a result of cation ordering. Ion-beam-induced amorphization has been investigated by 1-MeV Kr2+ ion irradiation with in situ transmission electron microscopy. The critical amorphization dose was determined as a function of temperature and the degree of structura...

Structural Transition in Random Mappings

In this paper we characterise the structural transition in random mappings with in-degree restrictions. Specifically, for integers 0 6 r 6 n, we consider a random mapping model T̂ r n from [n] = {1, 2, . . . , n} into [n] such that Ĝn, the directed graph on n labelled vertices which represents the mapping T̂ r n , has r vertices that are constrained to have in-degree at most 1 and the remaining v...

Benchmarking Structural Change in Transition *

The transition to market-based economic systems in the countries of Central and Eastern Europe and the former Soviet Union involves fundamental shifts in the allocation of resources and deep changes in the structure of production and employment. This paper uses a simple model of economic development and structural change with technology spillovers to benchmark structural change in the transitio...
