Ti–C bonds reinforced TiO2@C nanocomposite Na-ion battery electrodes by fluidized-bed plasma-enhanced chemical vapor deposition
No full textCarbon coatings hold great promise for next-generation non-conductive energy storage nanomaterials. However, simplicity, stable, uniformity and high-performance remain unresolved issues. Here, unique synergy of the fluidized bed reactor with plasmas enables highly-effective, single-step fluidized-bed plasma-enhanced chemical vapor deposition (FB-PECVD) of uniform, low-temperature carbon coatings on TiO2 nano-powder (TiO2@C). Plasma-specific effects induce the formation of new phases that are beneficial for energy storage. The 6 nm carbon layer is grown within only 10 min, while the TiO2 maintains its anatase phase. The unique plasma conditions make it possible to form Ti–C bonds at the Ti/C interface at much lower temperatures than achievable otherwise. The electronic transport at the interface and structural stability are thus greatly improved. Consequently, TiO2@C shows excellent electrochemical performances as a negative electrode of sodium ion battery, such as specific discharge capacity of 290.2 mA h g−1 at 50 mA g−1 and very stable long-term cyclability (101.2% capacity retention over 300 cycles at 4000 mA g−1). Our results show that FB-PECVD is not only a versatile method for bond-reinforced interface nanoparticle coating with carbon, but also provide a new strategy for designing hybrid-phase electrochemically active nanocomposite materials.No Full Tex
Future Trends of Virtual, Augmented Reality, and Games for Health
No full textSerious game is now a multi-billion dollar industry and is still growing steadily in many sectors. As a major subset of serious games, designing and developing Virtual Reality (VR), Augmented Reality (AR), and serious games or adopting off-the-shelf games to support medical education, rehabilitation, or promote health has become a promising frontier in the healthcare sector since 2004, because games technology is inexpensive, widely available, fun and entertaining for people of all ages, with various health conditions and different sensory, motor, and cognitive capabilities. In this chapter, we provide the reader an overview of the book with a perspective of future trends of VR, AR simulation and serious games for healthcare
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
