Renewable energy is a basic ingredient for overall sustainable development. Renewable fuel sources have the potential to provide energy supplies for an indefinite period of time. First generation biofuels have good fuel properties and their production processes are commercially well developed and successfully implemen…
The real world of polymer translocation is far more complex than the rudimentary physical models developed in the preceding chapters. The complexity of the phenomenon arises due to particular combinations of entropic contributions from polymer conformations and energetic contributions from polymer-pore interactions th…

The quality of any analytical system depends primarily on the sample analyzed. A sample must be representative of the environmental system from which it is taken so that chemical analysis results, in turn, represent the system.
The essence of chemical science finds its full expression in the words of that epitome of the artist-scientist Leonardo da Vinci: “Where Nature finishes producing its own species, man begins, using natural things and with the help of this nature, to create an infinity of species.” Nobel laureate Jean-Marie Lehn has us…
While many llers approach being spherical in geometry, some are ber-like. When the length of these brous materials approaches 100 times their thickness, many combinations offer great increases in the strength-related properties of the materials that contain them. If these bers are contained within a continuous phase,…
Interest in this area of potential human hazard stems, in part, from the magnitude of harm or damage that an individual who is exposed can experience. It is widely known that the risks associated with exposures to ionizing radiation are significantly greater than comparable exposures to non-ionizing radiation. This fa…
In Figure 5 we give an example. By slightly shifting the objective away from the plane of the nanocrystal core towards the bottom SiO2 layer, strikingly different PL spectral shapes are observed. In Figure 5a when the objective is aligned with the waveguide core, a smooth Gaussian curve is detected, which is character…

The mechanism for water vapor permeation through hydrophilic films is extremely complex. The complexity is due to nonlinear water sorption isotherms and water content dependent diffusivities (Schwartzberg, 1986). Hydrophilic films are usually used in applications where water vapor migration is not detrimental or water…
In 1956, Elvis Presley released his own faster and more syncopated version of a slow blues song recorded 4 years earlier by Willie Mae “Big Mama” ornton. For both ornton and Presley, this song, titled Hound Dog, rose to the top of the charts. In Elvis Presley’s rendition, the rhythmic patterns produced by the snare dr…
In recent years, there has been a renewed interest in the use of nuclear power to meet the world’s energy needs; this stems from concerns over climate change, energy security, and a forecasted increase in the global demand for electricity [1].

In this chapter, we present a powerful method of solving the Bloch equations or the master equation of a driven system called the dressed-atom model. The method is valid in situations where the Rabi frequency of the applied driving field is much larger than the spontaneous emission rate of the atom, . Under such condit…

INTRODUCTION The theory of two-ports was invented many years ago as a method to analyze networks with practically zero computational resources: small networks are analyzed in a special way and their interconnections are handled by the two-port rules. Since the arrival of computers the two-port theory lost its importan…
Theoretically, separating the solids into two classes, diamagnetic and paramagnetic, is obvious. However, in practice, it is well known that the synthesis of materials, involving a number of various organic and inorganic reagents, generally leads to systems still containing paramagnetic impurities of a different natur…
In many disciplines surfaces are more important than bulk structures. Mechanical interac-tion between parts involves friction and wear between surfaces, many chemical interac-tions take place on surfaces (including catalysis), and most modern electronic devices consist of thin layers of materials laid down in intricat…
The size and the shape of polymers are intimately connected to their properties. The shape of polymers is also intimately connected to the size of the various units that comprise the macromolecule and the various primary and secondary bonding forces that are present within the chain and between chains. This chapter co…
As you studied Chapter 12, and did the exercises developing the basic properties of functions of several variables, you should have noticed that many of the proofs were identical to those in Chapters 5 and 6. The arguments generally involved clever use of the triangle inequality. For functions of one variable, the ine…
