This book was released on 2006 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magnetorheological fluids belong to the class of field-responsive fluids that undergo large, reversible and fast changes in their rheological properties when acted upon by an external magnetic field. 'Smart' or controllable composite materials have been obtained by doping polymers, foams, fabrics etc. with these field-responsive fluids. The resulting composite materials have potential applications in numerous fields ranging from adaptive energy absorption, automotive crash protection to microfluidic valves, mixers and separation devices. A series of stable magnetorheological (MR) fluids have been systematically characterized under steady shearing, creep and large amplitude oscillatory shear (LAOS) flow conditions. A rheometer fixture for applying nearly uniform magnetic fields up to 0.4 T has been fabricated to measure both steady-state and transient changes in the fluid properties under applied fields. Stable MR fluids with a markedly improved dynamic response (yield stress as a function of magnetic field) compared to commercial fluids have been formulated by increasing the constituent particle size and by stabilizing the system against sedimentation. A new "soft-glassy rheology" model has been used to model the fluid response time and visco-elasto-plastic response under creep conditions and oscillatory loadings.

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magneto-rheological fluids (MRFs) and magneto-rheological elastomers (MREs), as smart materials, have been widely studied in various engineering fields to address vibration issues because the mechanical properties are controllable under the strength of a magnetic field. Their tribological characteristics are also important to be evaluated, as applications using MRFs and MREs contain various contact interfaces under reciprocating and rotating working conditions. The performance and durability of these materials are related to their tribological characteristics. Therefore, various working conditions and environmental conditions are taken into consideration, and their tribological characteristics are experimentally examined. In addition, applications using MRFs and MREs are introduced, and the tribological performances of these materials are evaluated.
Download or read book Multi physical Characterization of Micro and Nanomaterials written by Juntian Qu and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Functional micro- and nanomaterials possess exceptional mechanical, electrical and optical properties compared with their bulk counterparts, and these multi-physical properties have significantly benefited their diverse applications to a variety of scientific and engineering problems. The multi-physical properties of these micro- and nanomaterials need to be characterized accurately and efficiently to facilitate both material synthesis and device application.Among various experimental tools for micro- and nanomaterial characterization, micro-electro-mechanical systems (MEMS) were often employed for mechanical characterization. However, most of them are limited to one-axis actuation or sensing and thus can only be applied to perform single-axis compression or tensile testing. Besides, for nanomaterial characterization, the emerging technique of nanomanipulation under scanning electron microscopy (SEM) has enabled various multi-physical characterization experiments of nanomaterials such as electrical and mechanical measurements. However, the existence of contact resistance during SEM in-situ electrical nanoprobing could affect the measurement accuracy; therefore, it is highly desired to minimize the contact resistance during electrical characterization of nanomaterials.Moreover, multi-physical properties of nanomaterials not only exist in their independent states, but also often coupled with each other and closed correlated. However, SEM was not often utilized for optical or optoelectronic characterization of nanomaterials, which is attributed to the challenge of integrating optical components inside a limited-space SEM chamber, as well as the limited light collection efficiency. Therefore, it is a clear demand for the development of a SEM-based in-situ nanomanipulation system capable of characterizing the mechanical, electrical, optical, and multi-field-coupled properties of nanomaterials.In this thesis, in order to solve abovementioned challenge for mechanical characterization of micromaterials, a MEMS microgripper was developed to achieve, for the first time, microscale elastic and viscoelastic characterization of soft materials in both compressive and shear directions. A systematic investigation of the contact resistance in SEM in-situ electrical characterization of nanomaterials was carried out employing the two-point in-situ nanoprobing technique, and experimental strategies have been identified to minimize the sample-probe contact resistance. The optimized SEM in-situ electrical nanoprobing system was subsequently applied to electrical characterization of single n-i-n-n+ GaN nanowires (NWs), which revealed superior electrical breakdown properties of the GaN NWs. Finally, by integrating techniques for mechanical, electrical and optical characterization of nanomaterials, the first SEM-based nanomanipulation system for in-situ multi-physical characterization of nanomateirals was developed, which allows in-situ comprehensive opto-electro-mechanical characterization of individual nanostructures with high accuracy and efficiency. Using this system, the effect of mechanical stress/strain on the optoelectronic properties of single InGaN/GaN NWs was systematically investigated for the first time, providing valuable experimental data for better understanding the material's complex coupling-field properties with significant implication in group III nitride NW-based nanoelectronics and optoelectronics. The developed characterization system will greatly facilitate the experimental investigation of multi-field-coupled properties of semiconductor nanomaterials and nanostructures"--
