Effects of Blade Discharge Angle, Blade Number and Splitter Blade Length

, 2017
Impellers with splitter blades are used for pumps and compressors in the design of turbomachines. Design parameters such as the number of blades, blade discharge angle and impeller discharge diameter impact affect pump performance and energy consumption. In this study, the effect of the number of blades (z=5, 6, and 7), blade discharge angles (beta(2b)=

Photo‐Patternable PEDOT:PSS for High Performance Organic Electrochemical Transistors

Advanced Materials, EarlyView.
Organic mixed ionic‐electronic conductors, such as PEDOT:PSS, are a special class of material capable of dual conductivity, making them a perfect choice to bridge biology and man‐made technology. PEDOT:PSS can be photo‐patterned by blending it with a photo‐sensitive interpenetrating network.
