The effect of electric and magnetic fields on the melt organization of a nematic cyclic siloxane liquid crystal
Autor: S. G. McNamee, Christopher K. Ober, W. Wade Adams, Timothy J. Bunning, C. M. McHugh, S. S. Patnaik
Publikováno v: Liquid Crystals. 18:787-794
The presence of periodic diffuse meridional reflections in the X-ray diffraction pattern of the nematic phase of a pentamethylcyclosiloxane compound with pendant mesogenic groups is examined as a function of temperature and frequency of an applied el

Nematic-smectic biphase of a main-chain liquid crystalline polyether
Autor: Y. S. Freidzon, Christopher K. Ober, S. G. McNamee, E. Hall, A. A. Robinson
Publikováno v: Journal of Materials Science. 30:2023-2028
Shear alignment studies of a semirigid, main-chain liquid crystalline polymer found very different behaviour within a low temperature, birefringent phase than within the higher temperature, nematic phase. Using X-ray scattering techniques and thermal

Probing the electric field alignment of a thermotropic liquid crystalline polymer by synchrotron radiation
Autor: C. M. McHugh, W. Wade Adams, Christopher K. Ober, S. G. McNamee, Timothy J. Bunning
Publikováno v: Liquid Crystals. 17:179-190
The orientation of a cyclic side-chain thermotropic liquid crystalline material in an AC field was monitored in real-time using synchrotron radiation. Monitoring the realignment processes in the millisecond-to-minute time-scale was made possible by t

The mechanical and magnetic alignment of liquid crystalline epoxy thermosets
Autor: David W. Wang, Christopher K. Ober, George G. Barclay, Konstantinos I. Papathomas, S. G. McNamee
Publikováno v: Journal of Polymer Science Part A: Polymer Chemistry. 30:1845-1853
The processing of a new series of liquid crystalline (LC) epoxy networks was evaluated. Above the glass transition temperature, the low crosslink density networks could be mechanically aligned. The mechanically oriented networks readily lost orientat

The effect of repeated ethylene oxide sterilization on the mechanical strength of synthetic absorbable sutures
Autor: T O, Woods, S A, Brown, K, Merritt, S G, McNamee, V M, Hitchins
Publikováno v: Biomedical instrumentationtechnology. 35(6)
The purpose of this study was to determine the effect of repeated ethylene oxide sterilization using a standard clinical protocol on sutures, a type of medical device labeled for single use and reported to be reprocessed for use after being opened bu

An investigation of the smectic-isotropic transition in a side-chain liquid crystal polymer by synchrotron radiation X-ray diffraction
Autor: Giancarlo Galli, Christopher K. Ober, S. G. McNamee
In this work we have used synchrotron x-radiation diffraction to follow in real-time the isotropic-smoetic phase transition of a side-chain liquid crystalline polymer. The analysis of the x-ray data indicated that the transition occurs within a very
