King for all his support throughout my studies. His encouraging words and support all the time has helped me to realize my fullest my dreams. I want to thank him for developing my understanding of the challenging and at the same time rewarding relationship between medical textiles and clinical practice. I would also like to thank Dr. Shiara Ortiz Pujols and Dr. Bruce A. Cairns for introducing me to the world of burn wound care and providing me with a task that until now has been overlooked and is a real challenge. Their guidance has helped me in understanding donor wounds site and how to obtain reliable qualitative and quantitative data from a questionnaire instrument. I also would like to thank Dr. William F Gilly and his colleague Patrick of Stanford University for providing me with unique chitin materials derived from Humbodlt squid taken from California Bay, Dr. Joel Sohn of Harvard University for providing me with loligo squid pens from the seas off Thailand and Japan. I also appreciate them sharing their expert opinions. I also want to thank Simon McCarthy from Hemcon ® for his expert advice and samples, Lynne Rose, for providing me with samples of Silverclear ®, Dr. Debra Clare in the NC State University Food and Nutrition Sciences for helping me to perform my protein analysis assays, Judy Elson for providing me with chemicals and supplies and letting me use her laboratory.

Fiber-based nonwovens with 0.2, 0.5, 1, and 3 wt% of MWCNTs were characterized regarding conductivity, morphology, thermal, and mechanical properties. It was confirmed that an increase of the MWCNTs content does not influence the increase of the material conductivity, since the conductivity was 170 ohm sq À1 for all composites. Scanning electron microscopy and transmission electron microscopy analyses revealed that smooth and beadless fibers were obtained, but also average diameters of composite nanofibers decreased with the increase of the MWCNTs content. Differential scanning calorimetry analysis showed that the presence of MWCNTs in the PLA matrix had a significant influence on the crystallization behavior of PLA nanofibers, because the decrease in crystallization temperature (T c) was detected. Also, the incorporation of MWCNTs into PLA fibers affected the melting process, enabling the generation of a 0 form, while had no influence on ordered a crystal. The enthalpy of composite degradation decreased, because MWCNTs are well-known for good heat conductivity, and with that the second step of degradation slowed down, as it was confirmed by thermogravimetric analysis.

Requirements and Efficacy of Donor Site Wound Dressings and an Investigation on the Use of Chitin/Chitosan as Dressing Materials. (Under Direction of Martin W. King and Abdel-Fattah Mohamed Seyam.) Burn wounds are one of the leading accidental injuries around the world. One of the surgical procedures in the treatment of burn wounds is the use of donor site skin autografts harvested from the patients themselves. Such surgical procedures create another type of injury called a donor site wound. From a nursing or clinical management point of view there does not appear to be a standardized procedure for treating donor site wounds. Sometimes they are treated in the same way as burn wounds although the wound etiology is completely different. So the initial part of our research involved developing and administering a questionnaire that asked the personnel who work in burn units about their normal clinical practices and use of various dressings for the treatment of donor site...

This study compares fabric treated with a novel quaternary ammonium compound-based antimicrobial treatment with untreated fabric, using a new method for determining the antimicrobial efficacy of fabrics and textiles. The effects of contact temperature, contact time, and bacterial load were demonstrated. The lowest concentrations of bacterial cells were killed very quickly. Increasing contact time resulted in inactivation of larger numbers of cells, as did elevating temperature from 24 °C to 37 °C. Important physical properties of the fabrics were retained. The simplicity, and good reproducibility, of the test procedure supports its use for the rapid screening and assessment of fabric specimens for antimicrobial activity.
