Nanoferroics

by A. V. Ragulya M. D. Glinchuk Vladimir A. Stephanovich

This book covers the physical properties of nanosized ferroics, also called nanoferroics. Nanoferroics are an important class of ceramic materials that substitute conventional ceramic ferroics in modern electronic devices. They include ferroelectric, ferroelastic, magnetic and multiferroic nanostructured materials. The phase transitions and properties of these nanostructured ferroics are strongly affected by the geometric confinement originating from surfaces and interfaces. As a consequence, these materials exhibit a behavior different from the corresponding bulk crystalline, ceramic and powder ferroics. This monograph offers comprehensive coverage of size- and shape-dependent effects at the nanoscale; the specific properties that these materials have been shown to exhibit; the theoretical approaches that have been successful in describing the size-dependent effects observed experimentally; and the technological aspects of many chemical and physico-chemical nanofabrication methods relevant to making nanoferroic materials and composites. The book will be of interest to an audience of condensed matter physicists, material scientists and engineers, working on ferroic nanostructured materials, their fundamentals, fabrication and device applications.

Nanofertilizers for Sustainable Agroecosystems: Recent Advances and Future Trends (Nanotechnology in the Life Sciences)

by Kamel A. Abd-Elsalam Mousa A. Alghuthaymi

Large-scale chemical fertilizer application causes irreparable damage to soil structure, mineral cycles, soil microbial flora, plants, and other food chains across ecosystems, culminating in heritable mutations in future generations of consumers. A better way forward is the use of nanofertilizers to focus on macro elements (N, P, K), as switching to nanofertilizers may result in large environmental benefits by replacing the majority of these nutrients. Furthermore, the biosynthesis of nanomaterials using bacteria, algae, yeast, fungus, actinomycetes, and plants has opened up a new avenue of research in the production of inorganic nanoparticles as ecologically friendly fertilizers. Nanofertilizers should also attain increased efficiency because of a several-fold increase in the surface-to-volume ratio of nano-forms of nutrients and their suitability for foliar application, where environmental losses are further reduced. Nanostructured fertilizers can also improve nutrient use efficiency through strategies such as targeted distribution and progressive or controlled-release as they can precisely release their active molecules in response to environmental cues and biological demands. Recent research shows nanofertilizers can increase agricultural productivity by speeding up seed germination, seedling growth, photosynthetic activity, nitrogen metabolism, and carbohydrate and protein synthesis. The potential agricultural benefits of nanofertilizers, their modes of action, and the fate of nanomaterials in soil are all discussed in this book. It also covers nanofertilizer formulation and delivery, applications, uptake, translocation, and their fate in plants, as well as their impact on plant physiology and metabolism. Nutrient nanoformulation is a valuable method that has the potential to alter the agricultural sector and provide solutions to current and future concerns for sustainable and climate-sensitive crops

This subject is growing very fast from the technology as well as a science point of view. Books on this subject are very limited, particularly those ones that deal with both the science as well as the technology aspects.

Nanofins

by Navdeep Singh Debjyoti Banerjee

Nanofins Science and Technology describes the heat transfer effectiveness of polymer coolants and their fundamental interactions with carbon nanotube coatings that act as nanofins. Heat transfer at micro/nano-scales has attracted significant attention in contemporary literature. This has been primarily driven by industrial requirements where significant decrease in the size of electronic devices/chips with concomitant enhancement in the heat flux have caused challenging needs for cooling of these platforms. With quantum effects kicking in, traditional cooling techniques need to be replaced with more effective technologies. A promising technique is to enhance heat transfer by surface texturing using nanoparticle coatings or engineered nanostructures. These nanostructures are termed as nanofins because they augment heat transfer by a combination of surface area enhancement as well as liquid-solid interactions at the molecular scale.
