Optimal stem cell therapy delivery to damaged areas of the heart after myocardial infarction has been hampered by inefficient homing of cells to the damaged site. However, using rat models, researchers in France have used a magnet to guide cells loaded with iron oxide nanoparticles to key sites, enhancing the myocardial retention of intravascularly delivered endothelial progenitor cells.
The future of electronics will be flexible. Not only will you be able to roll up your iPads and smart phones like a piece of paper, electronic devices will be invisibly embedded in the textiles you wear from baby diapers to doctors’ surgical gloves. To realize such devices, equally flexible power sources need to be integrated with the electronic devices. Textile yarns are an obvious choice. Researchers are already pushing ahead with electronic textiles (e-textiles), for instance by coating regular cotton yarns with single-walled and multi-walled carbon nanotubes and polyelectrolytes, thus making cotton fibers conductive. Addressing the power source issue, researchers have now found a simple way to provide cotton with a new function – storing energy.
Abakan announces that MesoCoat and Powdermet’s revolutionary, high performance PComP(TM) nanocomposite coatings, which are used to extend the life of mechanical components such as valves, pumps, hydraulic cylinders, bearings, actuators, motors and drive shafts, have been recognized as the most significant materials science innovation of 2012 by R&D magazine.
Researchers from North Carolina State University have found a way to create much slimmer thin-film solar cells without sacrificing the cells’ ability to absorb solar energy. Making the cells thinner should significantly decrease manufacturing costs for the technology.
