The possible impact of nanomaterials on future products and services is enormous.
This has led to a tremendous expansion in research and development efforts related
to nanoscale materials and devices. It has also raised new questions as to how these
products will influence the environment, human health, business, education, and
other areas of society. As with any emerging field, a vast amount of disconnected
information is emerging, often spread across multiple disciplines.
Silicon technology continues to progress, but device scaling is rapidly
taking the metal oxide semiconductor field-effect transistor (MOSFET) to its
limit. When MOS technology was developed in the 1960's, channel lengths
were about 10 micrometers, but researchers are now building transistors with
channel lengths of less than 10 nanometers. New kinds of transistors and
other devices are also being explored. Nanoscale MOSFET engineering
continues, however, to be dominated by concepts and approaches originally
developed to treat microscale devices...
Porous metal organic framework nanoscale carriers as a potential platform for drug
delivery and imaging, In the domain of health, one important challenge is the efficient delivery of drugs in the body using non-toxic nanocarriers. Most of the existing carrier materials show poor drug loading and or rapid release of the proportion of the drug that is simply adsorbed at the external surface of the nanocarrier.
Tools shape how we think; when the only tool you have is an axe, everything resembles a
tree or a log. The rapid advances in instrumentation in the last decade, which allow us to
measure and manipulate individual molecules and structures on the nanoscale, have caused
a paradigm shift in the way we view molecular behavior and surfaces. The microscopic details
underlying interfacial phenomena have customarily been inferred from in situ measurements
of macroscopic quantities. Now we can see and “finger” physical and chemical
processes at interfaces.

Single nanowire-based UV photodetectors for fast switching
Kamran ul Hasan1*, N H Alvi1, Jun Lu2, O Nur1 and Magnus Willander1
Abstract Relatively long (30 µm) high quality ZnO nanowires (NWs) were grown by the vapor-liquid-solid (VLS) technique. Schottky diodes of single NW were fabricated by putting single ZnO NW across Au and Pt electrodes. A device with ohmic contacts at both the sides was also fabricated for comparison.

Nanoscale physics, nowadays one of the most topical research subjects, has
two major areas of focus. One is the important field of potential applications
bearing the promise of a great variety of materials having specific properties
that are desirable in daily life. Even more fascinating to the researcher in
physics are the fundamental aspects where quantum mechanics is seen at work;
most macroscopic phenomena of nanoscale physics can only be understood and
described using quantum mechanics. The emphasis of the present volume is
on this latter aspect....
