Analytical and numerical calculations of threshold behavior and electro-optical characteristics in twisted chiral nematic layers are presented, when weak anchoring in the tilt and twist angle of the director is assumed. An analytical expression for t

The small-angle neutron scattering (SANS) data of 12 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine (POPC) dispersions at low lipid concentration (1 mg per 100-mg heavy water) prepared by 5, 9 and 29 extrusions through filters of pores with 50, 100

Isothermal titration calorimetry (ITC) measurements of the mixture of the cationic surfactant cetyl trimethyl ammonium bromide (CTAB) with negatively charged, 'hairy' copolymer latices (poly-(2,3-epoxypropylmethacrylate-co-methacrylic acid) in differ

A novel method of evaluating SANS curves is presented which for the first time allows the simultaneous determination of the internal geometry and hydration of single bilayers in unilamellar vesicles at high water excess. A multistrip model unambiguou

We present the basic formulae for the analysis of IR dichroism data in terms of molecular order parameters of lamellar systems considering the special case of the Attenuated Total Reflection experiment on thick films. The infrared order parameter is

A complete theory of surface nematic anchoring was developed earlier, including steric, dielectric, flexoelectric, and notably, surface polarization coupling mechanisms. In the last three cases surface electric field due to the adsorption of surface

The Langmuir-Blodgett technique was used for deposition of monolayer lipid films of dipalmitoyl phosphatidylcholine (DPPC) on glass with a variable surface density of lipid molecules. In a certain range of surface density these surfaces oriented home

Isothermal titration calorimetry (ITC) allows the measurement of composition-dependent mixing heats of amphiphiles. A number of experimental protocols are now established to measure molecular transfer heats between, for example, micellar and lamellar

We have studied the nionolayer phase behavior of various mixtures of dipalmitoylphosphatidylcholine (DPPC) with 4-cyano-4′-n-pentylbiphenyl (5CB) at the air/water interface by means of Langmuir technique and Brew-ster angle microscopy. The phase be

The molecular arrangement of 5CB confined within the cylindrical pores of Anopore membranes was characterized by means of the IR-order parameter obtained from linear dichroism measurements of selected IR absorption bands. The treatment of the experim
