Gas-phase mechanism for dioxin formation

Chemosphere, 2003
We consider the formation of dioxin in the gas phase through the combination of phenoxy radicals in the context of a recently published scenario regarding the possibility of forming highly chlorinated benzenes in poorly mixed systems. It is demonstrated that the production of free chlorine in fuel lean combustion systems and subsequent mixing and ...

Phase formation of associating polymers: gelation, phase separation and microphase formation

Advances in Colloid and Interface Science, 1996
Abstract Polymers exhibit a variety of condensed phases when some of their segments are capable of forming weak bonds which can be created and destroyed by thermal motion. Transition from one phase to another caused by such ‘ segment association ’ is reversible by the change of the temperature and the concentration, so that it is called ‘ reversible ...

Kinetics of interface alloy phase formation at nanometer length scale in ultra-thin films: X-ray and polarized neutron reflectometry

Progress in Materials Science, 2018
Multilayer thin films of various metal pairs present model systems for studying intermetallic alloy phase formation at interfaces of these heterostructures on annealing and help to understand the kinetics of phase formation.

Non-equilibrium phase formation

Proceedings, annual meeting, Electron Microscopy Society of America, 1990
The most important advantage of EM’s is in situ experiments on detailed processes of the same phenomena that occur in bulk materials. In recent years, in situ experiments with HVEM’s, in particular with a 3MV ultra-HVEM , has made it possible to create non-equilibrium phases, which do not exist in nature, or to control and design materials on an atomic

Adaptive phase formation in martensitic transformation

Physical Review B, 1991
It is shown that an appearance of an intermediate martensite phase called adaptive martensite may be expected if the surface energy of a boundary between two orientational variants of the normal martensite phase is very low and the typical lattice-mismatch-related elastic energy is high.

Phase Formation Reactions

2014
In the introduction to the topic of reaction kinetics, two important classes of reactions were identified, homogeneous and heterogeneous reactions. Heterogeneous reactions include reactions that result in solute transfer across stable planar interfaces, solute transfer across unstable nonplanar interfaces and phase formation reactions.

Formation of Tetrahedral Phases

1969
The properties of semiconducting compounds are governed primarily by the short-range order, i. e., by the chemical nature of atoms, the geometry of their distribution, and the absolute distances between them. The crystal structure of semiconducting compounds is a very important characteristic of the short-range order and, in the majority of such ...

Formation of interfaces in bicontinuous phases

Physical Review E, 1994
With the charge-frustrated model, this paper examines the structure of interfaces in bicontinuous oil-water-surfactant phases. We analyze the nonlinear model by variational perturbation theory with a reference system that explicitly allows for interfaces.

Phase Formation and Stability

2009
Locally similar icosahedral structural ordering between parent phase and nucleating phase is believed to be responsible for the frequently occurring formation of icosahedral quasicrystals from undercooled liquid alloys or during devitrification of metallic glasses.
