Structural Study of Langmuir-Blodgett Mono- and Multilayers of Poly(.beta.-hydroxybutyrate)

The mechanical stability of Langmuir]Blodgett multilayers

The properties and stability of confined Langmuir]Blodgett multilayers made of arachidic acid were investigated using the surface forces apparatus. Two different types of confined films were studied: one formed by bringing two separate LB films into molecular contact, the other formed by bringing one LB film into direct contact with mica. The measured thickness of confined ̊ Ž . material depends...

The Directional Dependence of Water Penetration into Langmuir-Blodgett Multilayers.

The relationship between the mass uptake and the swelling of arachidic acid Langmuir-Blodgett (LB) films exposed to water vapor was investigated. Combining sorption data from the quartz crystal microbalance with swelling data from the surface forces apparatus (SFA), it was found that films exposed to water vapor ( approximately 75% RH) absorb 0.22 moles water/mole LB film with an associated swe...

An x-ray absorption spectroscopy study of the zinc environment in Langmuir-Blodgett phospholipid multilayers.

For the first time x-ray absorption spectroscopy was used to investigate the Zn environment in Langmuir-Blodgett multilayers. The multilayers were taken as a model of the multilamellar structure of the myelin sheath, the membrane surrounding the nerve axon, which plays a crucial role for signal transduction along the axon. The layers were assembled from the phospholipid dilauroylphosphatidic ac...

Langmuir-Blodgett films of polyethylene

Langmuir-Blodgett nanorod assembly.

Techniques for directing the assembly of metal or semiconductor quantum dots into novel superstructures have been extensively pursued over the past decades.1-3 Recent interest has been drawn toward 1-dimensional nanoscale building blocks such as nanotubes, nanowires, and nanorods.4-14 If these one-dimensional nanoscale building blocks can be ordered and rationally assembled into appropriate 2-d...
