A design of high performance gas sensor array withdiscrete islands of Au catalyst for increasing of ZnO nanowire junctions
- 2013

Proceedings (redaktörskap) (refereegranskat)abstract
- In this study, an effective design for growth of ZnO nanowires directly on gas sensor chips is introduced. The design utilizes the dendrite islands of Au catalyst deposited between and on the Pt electrodes for the nanowires to grow on instead of a continuous seed layer or Au film. This lead to an increase of the nanowirenanowire junctions in the devices, as well as a reduction of the leak current that would occur through the mentioned alternative seed layer; resulting in a higher sensitivity. The results showed that the developed gas sensors could be used for monitoring of NO2 at low concentration.

A Study of Universal Design Principles Assessment
- 2012
-
Proceedings (redaktörskap) (refereegranskat)abstract
- Goal in this pilot study is to explore the effect of universal design principles on the user’s behavior as they use a system. It is found that the universal design principles are not really able to symbolize the system’s attitude towards user’s action on the system. This research result is a part of a larger and ongoing research effort to discover if a system is designed universally or not based on the design principles and thereby come up with new innovative universal design principles.
