We study the phase diagram of a one-dimensional, two-component (i.e., pseudo-"spin"-(1/2)) ultracold atomic Fermi gas. The two atom species can have different hopping or mass. A very rich phase diagram for equal densities of the species is found, containing Mott insulators and superfluids. We also discuss coupling such 1D systems and the experimental signatures of the phases. In particular, we ...

A novel in-die evaluation method of tablet capping tendency was proposed based on a force-displacement curve and stress relaxation parameter in a tableting process. In our previous study (Chem. Pharm. Bull., 59, 2011, Nakamura et al.), the phase diagram consisting of elastic recovery energy (E(e)) and plastic deformation energy (E(p)) of compressed powder, named as the E(e)-E(p) diagram, was pr...

Intercalation cotnpounds with one type of guest atom are pseudobinary systems as long as the host retains its structure, and the behavior of such compounds can often be understood with two-component models. '2 One component is then the guest and the other is the interstitial site where the guest resides. Similarly, intercalation compounds with two types of guests are pseudoternary systems. Addi...

The CMOS PLL based Frequency Synthesizer is a vital role in Receiver front end Sub component. The main objective of this paper is to design a high frequency of oscillation, less phase noise and power efficient PLL. In general, the PLL contains PFD, Loop Filter, VCO and Frequency Divider. The VCO is a critical component in Phase Locked Loop for low power CMOS designs. Here the Source Coupled VCO...

For a multi-component system, general formulas are derived for the dimension of a coex-isting region in the phase diagram in various state spaces.

a topical preparation containing aceclofenac was developed using an o/w microemulsion system. isopropyl myristate was chosen as the oil phase as it showed a good solubilising capacity. pseudo-ternary phase diagrams were used to obtain the concentration ranges of the oil, surfactant (labrasol) and co-surfactant (plurol oleique) for microemulsion formation. five different formulations were formul...

the aim of this investigation was to design and develop nanoemulsions (nes) as novel ophthalmic delivery systems for brinzolamide (bzd). phase behavior of quaternary systems composed of triacetin and capryoltm 90 (selected oils, screened through the solubility studies), various surfactants (namely, cremophor rh 40, brij 35, labrasol and tyloxapol), transcutol p (as co-surfactant) and water a...

objective(s): the objective of this study was to design a topical microemulsion of vit b12 and to study the correlation between internal structure and physicochemical properties of the microemulsions. microemulsions are thermodynamically stable mixtures of water, oil, surfactants and usually cosurfactants with several advantages for topical and transdermal drug delivery. the formulation of micr...
