The fluid mosaic model of Singer and Nicolson in 1972 shows how proteins are embedded in membranes. To elucidate the interactions between proteins and the surrounding lipids, stearic acid (SA) and bovine serum albumin (BSA) were used as lipid-protein components to mimic the normal membrane bilayer environment using the Langmuir-Blodgett technique. Surface pressure (π)-molecular area (A) isother...

Giant hysteretic effects in the YHx hydrogen switchable mirror system are observed between x51.9 and x53 in pressure composition isotherms, optical and electrical properties, and mechanical stress. Polycrystalline Y films are studied by simultaneous in situ measurements of electrical resistivity, optical transmittance and x-ray diffractometry. These experiments are linked to optical microscopy ...

We investigate isothermal diffusion and growth of micron-scale liquid domains within membranes of free-floating giant unilamellar vesicles with diameters between 80 and 250 μm. Domains appear after a rapid temperature quench, when the membrane is cooled through a miscibility phase transition such that coexisting liquid phases form. In membranes quenched far from a miscibility critical point, ci...

A New-PVE lubricant was developed for use with R32 refrigerant. R32 has been proposed as an alternative refrigerant for R410A refrigerant, to reduce global warming. In this report, we evaluated the relationship between the New-PVE lubricant and R32 and R410A refrigerants. The evaluation items were physical properties (miscibility, solubility, mixture viscosity and volumetric resistivity) and th...

Proper handling of produced sour gas is a big challenge for operating companies due to the serious environmental and technical problems caused by H2S. Among various processing methods, reinjection into reservoirs cost-effective environmentally-friendly technique that not only enhances oil recovery but also allows underground storage The high safety requirements working with toxic H2 S have supp...

We use 2H NMR to study the effects of probes on the miscibility transition in multilamellar vesicles of di(18:1) phosphatidylcholine (PC; DOPC), chain perdeuterated di(16:0)PC (DPPCd62), and cholesterol both with and without 0.5 mol % of the fluorescent probes DiIC12 and DiOC18. Both probes raise the miscibility transition temperature in dispersions of 1:1 DOPC/DPPCd62 + 30% cholesterol but to ...

I consider the effect of a small concentration of a molecule, such as a short-chain alcohol, on the miscibility transition temperature of a giant plasma membrane vesicle. For concentrations sufficiently small such that the system can be treated as a weak solution, the change in transition temperature is known to depend upon the extent of the molecule’s partition into the coexisting liquid-disor...

Vinylether monomers offer unique properties for UV/EB curing due to their efficiency as reactive diluents and their ability to undergo both cationic homopolymerization and free-radical copolymerization. The benefits derived from the inclusion of vinylethers into commercial UVcurable epoxysilicone formulations include viscosity reduction, improved cationic photoinitiator miscibility, and lower c...
