The purpose of functional elements is to act as the elements of design in the functional domain, just as standardized components (bolts, bearings, resistors, ICs, etc.) act as the elements of design in the physical domain. And the criterion for making something into an element is the same in both cases — usefulness. T…
This chapter presents the investigation results of the influence of metal/carbon nanocomposites on heat-physical and viscous properties of silicate compositions. The introduction of nanocomposite facilitates the decrease in material temperature conductivity by nearly 50%. The article discusses the investigation result…

Modification of polycarbonate with copper/carbon nanocomposite was investigated. The changes in spectral, optical and thermal-physical characteristics of compositions based on polycarbonate modified with copper/carbon nanocomposites were observed.
The controlled synthesis of gold or silver nanostructures has attracted considerable attention because of their widespread use in catalysis, photonics, electronics, optoelectronics, biological labeling, imaging, sensing, and surface-enhanced Raman scattering (SERS) (Chen et al. 2005b; Maier et al. 2001; Taton et al. 2…
In understanding the effects of various lubricants and how they affect machine life, it makes good sense to first look at some simplified versions of how the basic bearing types work, then review how lubricants are formed, and then return for a more detailed look at various applications and how lubricants affect them.
Carbon materials possess excellent mechanical, tribological, and biological properties, and as a result, carbon-based materials nd applications in biomedical devices including cardiovascular, orthopedic, and dental applications [1-3].

In this book we have considered an interesting phenomenon, which has important fundamental and practical applications-the magnetocaloric effect (MCE), displaying itself in changing magnetic entropy and temperature of a magnetic material under application of a magnetic field. We have discussed theoretical approaches to t…
Single-sample methods illustrate basic ideas, but have limited applications. Practical problems usually involve two or more samples that may or may not be independent. We consider paired samples in this chapter, a dependentsample situation where many, but not all, problems reduce to a single-sample equivalent.
The understanding of transport properties in graphene has become a topic of great interest not only because of the underlying fascinating physics, but also because of the ¦ourishing graphene-based technologies in elds such as ¦exible displays, high-frequency devices, composite materials, or photovoltaic applications.…

We have briefly discussed the bottom-up approach (Fig. 7.1) for the preparation of quantum dots and quantumwires in Section 6.3. In this chapter, let us look at some basic details of this approach. This will require some fundamental concepts in thermodynamics — i.e. the study of energy exchanges between physical syste…
Manufacturers: There are over 200 major manufacturers of general purpose polymers and numerous other manufacturers of specialty polymers. Processors: Some companies manufacture their own polymeric materials for subsequent processing, but the majority purchases the necessary polymeric materials from other companies. Pr…
Metabolic syndrome (MetS) is the name given to a group of risk factors that increase an individual’s risk of CHD and other related problems including diabetes and stroke. Th ese include: abdominal adiposity (as defi ned by a large WHR); a higher than normal triglyceride level; a lower than normal level of high density…
From their discovery, ferroelectrics were more of academic interest, of little application and theoretical relevance. e recognition of the relationship between lattice dynamics and ferroelectricity as well as the modeling of ferroelectric phase transitions has intensi ed the investigations of ferroelectrics. e focus c…
The sequential passage of liposomes through filters of a defined pore size to generate large unilamellar vesicles (LUV) with a mean diameter reflecting the diameter of the filter pore was first described 25 years ago (1). In the 1970s, making LUV was an arduous process, often taking several days and severely limiting the r…
INTRODUCTION The development of regulatory framework for the regulation of nanomaterials is critical to the future of virtually every potential application of what is commonly referred to as nanotechnology. It is vital that the regulatory process be coherent and avoid mistakes made in developing regulatory frameworks…
Experiment 10 – absorption of gamma radiation The objectives of this experiment are to measure the attenuation of gamma radiations by aluminum and by lead, and to calculate the linear and mass absorption coefcients and the half value layers for each of them.
