　　 In recent years, the advances in microscale heat transfer and fluid flowwere remarkable and applications using microscale phenomena have become popular. Especially, innovations in electronic technology and biotechnology are striking.
　　 In 2008 ECI Conferences at Whistler, understanding these microscale phenomena has been improved. Nevertheless, it is needed to explore heat and fluid flow in further smaller scale, that is, nanoscale. A large number of experiments and numerical analyses are being carried out in many laboratories all over the world. However, there is a lack of synergy between the many researchesthat are currently in progress and this conference presents an auspicious opportunity for coordination of the many efforts at an international level.
