Morphology control for nano-phase separation structures
In recent years, morphology control has emerged as an important research topic in many fields such as chemistry, biology, and medicine for the development of highly efficient materials and functional structures of devices based on organic and inorganic materials and their hybrids. Once developed, these techniques will pave the way for a wide range of possibilities such as the creation of highly...
متن کاملFormation of regular structures in the process of phase separation.
Phase separation under directional quenching has been studied in a Cahn-Hilliard model. In distinct contrast to the disordered patterns which develop under a homogeneous quench, periodic stripe patterns are generated behind the quench front. Their wavelength is uniquely defined by the velocity of the quench interface in a wide range. Numerical simulations match perfectly analytical results obta...
متن کاملPhase Separation and Domain Interaction in Pheophytin Containing Monolayers
Surface pressure and fluorescence intensity of pheophytin containing lipid-monolayers are measured simultaneously at the air-water interface. A phase separation into two distinct phases is reported. Phase 1 exists of pheophytin domains whereas phase 2 is a lipid domain containing pheophytin in molar content between 2 % and 15 %, depending on the state of the lipid. The transition of the pheophy...
متن کاملDynamic domain formation in membranes: thickness-modulation-induced phase separation.
A simple model investigates the amplification of fluctuations on membranes constituted of two lipids having different lengths. Van der Waals and electrostatic interactions across the lipid bilayer result in a destabilization favoring thickness variations of the membrane. Close to spontaneous demixing of the two components, the additional gain in free energy due to thickness undulations shifts t...
متن کاملSource-filter separation of speech signal in the phase domain
Deconvolution of the speech excitation (source) and vocal tract (filter) components through log-magnitude spectral processing is well-established and has led to the well-known cepstral features used in a multitude of speech processing tasks. This paper presents a novel source-filter decomposition based on processing in the phase domain. We show that separation between source and filter in the l...
