Perspectives of parents on health benefits associated with taekwondo for adolescents and young adults with intellectual and developmental disability

 Taekwondo may serve as an important therapeutic programme to promote physical, social, cognitive and emotional health among adolescents and young adults with intellectual and developmental disability (IDD). Little research has explored the value of Taekwondo for health benefits among adolescents and young adults with IDD living in the United States. The purpose of this study was to capture health benefits associated with Taekwondo among adolescents with IDD from the perspectives of parents and observations. Using semi-structured in-depth interviews with eight participants, four salient themes were identified as health benefits that Taekwondo participation provided for their child: (a) emotional benefits, (b) social benefits, (c) cognitive benefits, and (d) physical benefit. The findings of this study indicate that Taekwondo can improve the physical, social, emotional, and cognitive functioning of adolescents and young adults with IDD and may be considered an effective mind-body exercise programme for promoting their health and well-being in these domains.

Exploring the correlation between MoS2 nanosheets and 3D graphene-based nanostructures for reversible lithium storage

Graphene-based materials are an attractive lithium storage material for next-generation lithium-based batteries due to its high capacity, surface area and conductivity. However, one of the major problems for its broad application in batteries is a large irreversible capacity, and the poor cycle stability and low rate capability remain. Here, we report a MoS2-stabilized hierarchical three-dimensional graphene-based nanostructure, in which the MoS2 layer acts as a stabilizer as well as an active material. We show that the presence of MoS2 thin layer adjacent to the graphene surface can improve lithium storage capability by improving lithium ion diffusion property with fast Li-ion transport kinetic. On the basis of experimental and theoretical approaches, we ascribe the improved reversible lithium storage to the unusual reversible Li-MoS2 redox reaction and charge distribution on the graphene and MoS2 interlayers. These findings will provide a potential new direction in the design of electrode materials for advanced lithium storage technologies

Oxide Nanomembrane Hybrids with Enhanced Mechano- and Thermo-Sensitivity for Semitransparent Epidermal Electronics

Oxide nanomembrane hybrids with enhanced mechano- and thermo-sensitivity for semitransparent epidermal electronics are developed. The use of nanomaterials (single wall nanotubes and silver nanoparticles) embedded in the oxide nanomembranes significantly enhances mechanical and thermal sensitivities. These mechanical and thermal sensors are utilized in wheelchair control and hypothermia detection, which are useful for patients with strokes. © 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Stretchable Carbon Nanotube Charge-Trap Floating-Gate Memory and Logic Devices for Wearable Electronics

Electronics for wearable applications require soft, flexible, and stretchable materials and designs to overcome the mechanical mismatch between the human body and devices. A key requirement for such wearable electronics is reliable operation with high performance and robustness during various deformations induced by motions. Here, we present materials and device design strategies for the core elements of wearable electronics, such as transistors, charge-trap floating-gate memory units, and various logic gates, with stretchable form factors. The use of semiconducting carbon nanotube networks designed for integration with charge traps and ultrathin dielectric layers meets the performance requirements as well as reliability, proven by detailed material and electrical characterizations using statistics. Serpentine interconnections and neutral mechanical plane layouts further enhance the deformability required for skin-based systems. Repetitive stretching tests and studies in mechanics corroborate the validity of the current approaches

Multifunctional wearable devices for diagnosis and therapy of movement disorders

Wearable systems that monitor muscle activity, store data and deliver feedback therapy are the next frontier in personalized medicine and healthcare. However, technical challenges, such as the fabrication of high-performance, energy-efficient sensors and memory modules that are in intimate mechanical contact with soft tissues, in conjunction with controlled delivery of therapeutic agents, limit the wide-scale adoption of such systems. Here, we describe materials, mechanics and designs for multifunctional, wearable-on-the-skin systems that address these challenges via monolithic integration of nanomembranes fabricated with a top-down approach, nanoparticles assembled by bottom-up methods, and stretchable electronics on a tissue-like polymeric substrate. Representative examples of such systems include physiological sensors, non-volatile memory and drug-release actuators. Quantitative analyses of the electronics, mechanics, heat-transfer and drug-diffusion characteristics validate the operation of individual components, thereby enabling system-level multifunctionalities. © 2014 Macmillan Publishers Limited.
