Quantitative approaches of nanofibers organization for biomedical patterned nanofibrous scaffold by image analysis.

This study proposes a novel design of a laboratory built static collector using the 3D printing technology. This new collector produces aligned-to-random nanofibers in nanofibrous scaffold through electrospinning process. A design of experiment (DOE), based on response surface, analyzes the effect of the main process parameters; concentration, voltage, and distance; on the responses diameter and orientation. A quantifying approach has been used to investigate the orientation of nanofibers in the produced patterned scaffold through Fourier transforms method. The obtained results have proven a good potential to be used in tissue engineering application, especially for cells requiring specific guidance. © 2018 Wiley Periodicals, Inc.

The influence of the sterilisation process on certain thermal properties.

Surgical clothing and sheets have to meet all the requirements set in the health-care industry regarding body comfort, absorption capacity and general recognition of physiological safety and sterilisation capacity. The disposable surgical gown market is growing and the demand will increase in all product groups and market sectors, where the health care industry is the most dynamic growth area. The aim of this study was to analyse some of the thermal properties of disposable surgical gowns before and after different sterilisation methods, and therefore the influence of the sterilisation process on their thermal comfort. The apparatus used to measure heat transfer properties was the Thermo Labo device (KES FB7) which evaluates the cool/warm sensation, thermal conductivity and insulation properties of the test item. The results obtained highlight the influence of the sterilisation process on the thermal and comfort properties.
