Researchers used a hydrogel to mimic the heart cells. They added carbon nanotubes to the hydrogel, making it conductive, and then injected the material into the heart, where it solidifies at body temperature.
Engineers combine layers of flexible materials into pressure sensors to create a wearable heart monitor thinner than a dollar bill. The skin-like device could one day provide doctors with a safer way to check the condition of a patient's heart.
Inspired by the structure of moth eyes, researchers at North Carolina State University have developed nanostructures that limit reflection at the interfaces where two thin films meet, suppressing the "thin-film interference" phenomenon commonly observed in nature. This can potentially improve the efficiency of thin-film solar cells and other optoelectronic devices.
Physikern an der Universität Wien ist es gelungen, eine einzigartige Nano-Struktur aus Kohlenstoff zu züchten, die einem winzigen gezwirbelten Schnurrbart ähnelt. Ihre Methode könnte wegweisend für die Bildung komplexerer Nano-Netzwerke sein.
Physicists have found out how tiny islands of magnetic material align themselves when sorted on a regular lattice. Contrary to expectations, the north and south poles of the magnetic islands did not arrange themselves in a zigzag pattern, but in chains.
A team of researchers have directly observed a rare quantum effect that produces a repeating butterfly-shaped energy spectrum, confirming the longstanding prediction of this quantum fractal energy structure called Hofstadter's butterfly.
Materials nanoarchitectonics has led to important innovations in the design and construction of systems in nanoelectronics, nanomachinery, and energy conversion. Recent publications point to the fact that the same approach may be applied successfully to other fields.
In search of low-friction components for ever smaller components, a team of physicists led by the professors Thorsten Hugel and Alexander Holleitner now discovered a previously unknown type of friction that they call 'desorption stick'.
By adding semiconducting nanoparticles to polymers, the Materials + Technologies Research Group (GMT) of the Polytechnical College of San Sebastian of the UPV/EHU-University of the Basque Country has created nanostructured composite materials with specific optical and electrical properties that vary according to size.
