The Use of Nomenclature in Dispersion Science and Technology (Classic Reprint)


Book Description

Excerpt from The Use of Nomenclature in Dispersion Science and Technology The use of nomenclature for describing dispersed particulate systems, along with their associated properties and components, is often inconsistent and sub ject to misinterpretation in the technical and scientific literature. For example, terms for describing the state of association of particles in suspension (e. G., aggregate or agglomerate) often carry specific connotations that vary among different authors. This guide has been prepared as a resource for researchers, engineers and students working in dispersion-based applications. In compiling this guide, we drew on a number of resources, including books, review articles and published terminologies. To the extent possible, every effort was made to maintain a degree of uniformity with existing standards and conventions, including published terminologies from the American Concrete Institute (aci), the British Standards Institute (b si), the International Union of Pure and Applied Chemistry (iupac) and the Society of Rheology, as well as current and draft astm and iso standards. We intend this guide to serve as a resource for practitioners working in various fields in which ceramic dispersions are used, where ceramic is broadly defined as a non-metallic inorganic material. Equations have been used sparingly, and only where necessary for clarity or where they are integral to the subject at hand. This is not, nor is it intended to be, an exhaustive compilation. Rather, this document focuses on commonly encountered terms, and endeavors to provide a consistent framework for improved technical communication. The technical nomenclature portion of this guide is divided into two sections. The first section is derived from Special Publication 945, and deals with general topics related to dispersion science and technology, such as particle agglomeration and colloidal stability. The second section is based on Special Publication 946, and provides definitions of terms and expressions relating to the measurement of rheological properties in liquid-based ceramic dispersions suspensions, pastes and gels).

Electrorheological Fluids


Book Description

An electrorheological (ER) suspension is made from an insulating liquid medium embodying either a semi-conductive particulate material or a semi-conductive liquid material (usually a liquid crystal material). Since its mechanical properties can be easily controlled over a wide range (almost from a pure liquid to a solid), the ER fluid can be used as an electric and mechanical interface in various industrial areas, for example, in the automotive industrial for clutch, brake and damping systems and in robotic arm joints and hands. In addition, the ER technique can be used to fabricate advanced functional materials such as photonic crystals, smart inks, and heterogeneous polymer composites. The major objective of Electrorheological Fluids is to present a comprehensive survey on the ER suspensions in term of screening high performance ER materials, physical mechanisms of the ER effect, and the applications of ER technology. * Applications of ER suspensions are of wide interest both in academia and industry * Surveys a large body of literature on the mechanism of the ER effect and the design of industrially applicable ER devices * Discusses technological problems affiliated with industrial applications




Characterization of Liquids, Dispersions, Emulsions, and Porous Materials Using Ultrasound


Book Description

Characterization of Liquids, Dispersions, Emulsions and Porous Materials Using Ultrasound, Third Edition, presents a scientific background for novel methods of characterizing homogeneous and heterogeneous liquids (dispersions, emulsions, and gels) as well as porous materials. Homogeneous liquids are characterized in rheological terms, whereas particle-size distribution and zeta potential are parameters of heterogeneous liquids. For porous materials, porosity, pore size, and zeta potential are output characteristics. These methods are based on ultrasound, which opens an opportunity for simplifying the sample preparation by eliminating dilution. This in turn, makes measurements faster, easier, precise, suitable for accurate quality control, PAT, and formulation of complex systems. This book provides theoretical background of acoustics, rheology, colloid science, electrochemistry, and other relevant scientific fields, describing principles of existing instrumentation and, in particular, commercially available instruments. Finally, the book features an extensive list of existing applications. Presents a theoretical multi-disciplinary background of several new ultrasound analytical techniques in one place Validates the theoretical basis of several new analytical techniques Compares the efficiency and applications of various ultrasound techniques Lists many ultrasound applications in colloid chemistry Contains an extensive bibliography on this multidisciplinary topic

An Assessment of the National Institute of Standards and Technology Measurement and Standards Laboratories


Book Description

This assessment of the technical quality and relevance of the programs of the Measurement and Standards Laboratories of the National Institute of Standards and Technology is the work of the 165 members of the National Research Council's (NRC's) Board on Assessment of NIST Programs and its panels. These individuals were chosen by the NRC for their technical expertise, their practical experience in running research programs, and their knowledge of industry's needs in basic measurements and standards. This assessment addresses the following: The technical merit of the laboratory programs relative to the state of the art worldwide; The effectiveness with which the laboratory programs are carried out and the results disseminated to their customers; The relevance of the laboratory programs to the needs of their customers; and The ability of the laboratories' facilities, equipment, and human resources to enable the laboratories to fulfill their mission and meet their customers' needs.




Nanoparticle Technologies


Book Description

Nanoparticles (NPs) are spherical particles with a diameter less than 100nm. They will likely become important building blocks in several industrial sectors in the future. NPs are produced under different compositions, shapes, and structures often dispersed in a medium. NPs are classified according to their composition, properties, fabrication process, or applications. A simple classification could be obtained by dividing NPs into inorganic metals, inorganic semiconductors, inorganic insulators, and, finally, organics including polymers. Other classifications are based on the nature of the manufacturing process (chemical, physical, or biological), synthesis media (gas, liquid, or solid), energy source (sputtering, laser, microwave, convection, and sonochemical), and properties (optical, mechanical, or thermal). Besides increased surface area and reactivity, smaller particles may give rise to numerous improved mechanical, optoelectronic, thermal, and magnetic properties. NPs are often used with a core–shell structure obtained following the synthesis step or a post-synthesis process. In most cases, the value chain of commercial products involving NPs consists of NP production, formulation, integration, and system assembling. Toxicity and environmental issues are considered important issues requiring more R&D and education. In particular, improved life cycle inventory and life cycle analysis for different commercial and pre-commercial NP-based products are needed.
