Microdevices are developed to resemble the in-vivo micro-environment of ovule fertilization by pollen tubes in model research plant Arabidopsis thaliana. The PDMS-based microdevices are filled with pollen germination medium (PGM) providing pollen tubes with a proper growth environment. Pollen tubes are found to grow within the microgrooves with an average rate of 130 mum/hr, reaching a final tube...
To produce thick-walled, tubular components economically, the forming configuration in which a pressurising medium is used in injection forging has been simplified. FE and experimental analysis has been conducted to study the performance of the polymers that were used as the pressurising medium and to examine process design and component-quality issues. A testing method which uses a compound cylinder...
