Description
Nanoscience is the emerging science of objects that
are intermediate in size between the largest molecules and
the smallest structures that can be fabricated by current
photolithography; that is, the science of objects with smallest dimensions ranging from a few nanometers to less than
100 nanometers.[1–3] In chemistry, this range of sizes has historically been associated with colloids, micelles, polymer
molecules, phase-separated regions in block copolymers,
and similar structures—typically, very large molecules, or
aggregates of many molecules. More recently, structures
such as buckytubes, silicon nanorods, and compound semi conductor quantum dots have emerged as particularly interesting classes of nanostructures. In physics and electrical engineering, nanoscience is most often associated with quantum behavior, and the behavior of electrons and photons in
nanoscale structures. Biology and biochemistry also have a
deep interest in nanostructures as components of the cell;
many of the most interesting structures in biology—from
DNA and viruses to subcellular organelles and gap junctions—can be considered as nanostructures.

Design & Analysis of Algorithm
Trending!
We study data structures so that we can learn to write more efficient programs. But
why must programs be efficient when new computers are faster every year? The
reason is that our ambitions grow with our capabilities. Instead of rendering efficiency needs obsolete, the modern revolution in computing power and storage capability merely raises the efficiency stakes as we computerize more complex tasks.
The quest for program efficiency need not and should not conflict with sound
design and clear coding. Creating efficient programs has little to do with “programming tricks” but rather is based on good organization of information and good algorithms. A programmer who has not mastered the basic principles of clear design
is not likely to write efficient programs. Conversely, “software engineering” cannot
be used as an excuse to justify inefficient performance. Generality in design can
and should be achieved without sacrificing performance, but this can only be done
if the designer understands how to measure performance and does so as an integral
part of the design and implementation process. Most computer science curricula
recognize that good programming skills begin with a strong emphasis on fundamental software engineering principles. Then, once a programmer has learned the
principles of clear program design and implementation, the next step is to study the
effects of data organization and algorithms on program efficiency
