MODELING THE INTERDEPENDENCE OF ELECTROCHEMICAL AND MECHANICAL PROPERTIES IN PER SULFONATE ACID PROTON EXCHANGE MEMBRANES
PEM fuel cell membrane Conductivity Measurement
2015/1/12
Proton exchange membrane fuel cells (PEMFC’s) offer an attractive alternative energy resource over traditional fossil fuels. The advantages such as high power density, relatively quick start-up, rapid...
Properties and Applications of the Eccentric-gear Drive
eccentric gear transmission property variable speed transmission
2011/8/4
The eccentric-gear can be used for variable speed transmission. But, due to the vibrations caused by variation of backlash in working process, the eccentric-gear is seldom applied in engineering proje...

The Effects of Wall Properties on Peristaltic Transport of a Dusty Fluid
Peristaltic transport Wall properties Dusty fluid
2009/9/30
The interaction between peristaltic transport of a dusty fluid (Saffman’s model) in a 2-dimensional uniform channel and the elasticity of the channel’s flexible walls was studied under long wavelength...
Anisotropy of physical properties injection moulded parts and its analysis
Engineering polymers Mechanical properties Injection moulding
2010/2/10
Purpose: Anisotropy of physical properties in injection mouldings is a phenomenon commonly performing and very difficult to avoid. However in some cases for its size occurring of diversity of the prop...
