The emerging area of nanoscience and thin-film technology of materials holds promise for a wide range of scientific and technological applications. Nevertheless, much new science awaits its discovery, and novel fabrication strategies remain to be explored in this class of materials, particularly at the nanoscale, by using strategies based on nanoscience and thin-film technology. The challenge facing the scientists is to address the fundamental scientific question “why is it so great to be so small? ” in order to successfully utilize the nanoscale phenomena in device technology.

The present talk will focus on some of the issues in this direction and discuss thin-film and nanostructured materials with diverse structures, properties, and phenomena. The emphasis is to show that at the reduced dimensions extensive opportunities arise for utilization of materials in extremely diverse fields of technology, where high ratings, enhanced performance, and long-shelf lives are required.

Controlling the structure of thin magnetic films and metal-metal interfaces will be discussed for application in magneto-electronics. Thin oxide films will be discussed to show their potential ability as smart materials and/or intercalation compounds for application in electrochemical energy conversion and storage, optics, and electrohromics.

Some of the general issues will also be discussed in the context of the revolution that we are currently witnessing in nanoscience and to convince that it holds the greatest potential in shaping the world of the future.
