Liquid Crystalline Colloids of Nanoparticles: Preparation, Properties, and Applications

Abstract: Nanoparticle/liquid crystal colloidal dispersions are a new, rapidly developing, and exciting frontier of soft matter science and technological progress. This is both because of the dramatic changes in liquid crystal characteristics caused by adding nanoparticles and because of the limited understanding of the structure and interactions of the components of such composite systems. In this review, we summarize the basic science and applications of various nanoparticles, 1–100 nm in diameter, dispersed in liquid crystals. The historical development of this area of science is divided into two main periods. The first period, from the early 1970s until the year 2000, covers the structural organization and the interaction of passive nanoparticles (mostly dielectric) dispersed in liquid crystals. This period initiated the development of novel electro-optic effects and devices based on the properties of such composites. The second period covers progress during the first decade of the millennium. It is a Renaissance era in the development of liquid crystalline nanocolloids when the power of nanoscale was demonstrated to the full extent. Active nanoparticles, mostly ferroelectric, ferromagnetic, and ferroic, added to liquid crystals, shared their intrinsic properties with the liquid crystal host, and allowed for the creation of unprecedented materials with astonishing applications. These active particles generate ultrahigh electric and/or magnetic fields within the liquid crystal host, which, combined with their small size, produces a uniquely exciting and largely unexplored system of composite materials which exhibit novel collective particle–host interactions and which promise a variety of exotic electro-magneto-optic and other applications. These internally generated fields, larger than any macroscopic field that can be applied, serve both to spatially organize the particles and to couple the particle system to the liquid crystal thus enabling the liquid crystal ordering to affect the collective particle order. Although we have made an effort to review liquid crystalline/nanocolloids research as broadly as possible, many great results are omitted from this chapter. We hope this review will be an invitation to further explore this unique and exiting collection of knowledge.

Evaluating a GPS-Based Transportation Device to Support Independent Bus Travel by People with Intellectual Disability.

Abstract: We examined the utility of a PDA-based software system with integrated GPS technology for providing location-aware visual and auditory prompts to enable people with intellectual disability to successfully navigate a downtown bus route. Participants using the system were significantly more successful at completing a bus route than were people in a control group, who used a map and verbal directions. Further, when using the GPS-based system, 73% of participants successfully rang the bell and exited the bus at the right stop compared with only 8% of the control group. This finding was observed for individuals attempting to follow a new bus route for the first time and get off the bus at a previously unknown location.

System Health Management: With Aerospace Applications

Abstract: System Health Management: with Aerospace Applications provides the first complete reference text for System Health Management (SHM), the set of technologies and processes used to improve system dependability. Edited by a team of engineers and consultants with SHM design, development, and research experience from NASA, industry, and academia, each heading up sections in their own areas of expertise and co-coordinating contributions from leading experts, the book collates together in one text the state-of-the-art in SHM research, technology, and applications. It has been written primarily as a reference text for practitioners, for those in related disciplines, and for graduate students in aerospace or systems engineering.
