Structure evolution during uniaxial deformation of an unfilled 83% trans-polypentenamer sample is investigated as a function of temperature using in situ synchrotron wide-angle X-ray scattering (WA...

Isotactic and atactic poly(1-octadecene) (iPOD and aPOD) have been synthesized by organometallic coordinative insertion polymerization of 1-octadecene. Analyzing X-ray and neutron scattering data of POD melts identifies their bottlebrush structures a

Changes in the crystalline and mesoscale lamellar structure during plastic deformation of semicrystalline polymers have been extensively studied by X-ray diffraction techniques. However, direct measurements of single chain conformations during stretc

Control of permeability of phospholipid vesicle (liposome) membranes is critical to their applications in analytical sensing, in fundamental studies of chemistry in small volumes, and in encapsulation and release of payloads for site-directed drug de

Optical-trapping confocal Raman microscopy allows the 1, 4-addition reaction of diacetylenic functional groups in 1,2-bis(10,12-tricosadiynoyl)-sn-glycero-3-phosphocholine lipids to be monitored in individual phospholipid vesicles. Optical trapping a

Detection of single, fluorescently labeled biomolecules is providing a powerful approach to measuring molecular transport, biomolecular interactions, and localization in biological systems. Because the biological molecules of interest rarely exhibit

Few directed searches have been undertaken to identify the genes involved in vertebrate lens formation. In the frog Xenopus, the larval cornea can undergo a process of transdifferentiation to form a new lens once the original lens is removed. Based o

Small polymeric particles are increasingly employed as adsorbent materials, as molecular carriers, as delivery vehicles, and in preconcentration applications. The rational development of these materials requires in situ methods of analysis to charact

Few molecular comparisons have been made between the processes of embryogenesis and regeneration or transdifferentiation that lead to the formation of the same structures. In the amphibian, Xenopus laevis, the cornea can undergo transdifferentiation
