Calculations by the Rice lab of theoretical physicist Boris Yakobson found a graphene/boron anode should be able to hold a lot of lithium and perform at a proper voltage for use in lithium-ion batteries.
Scientists with the Lawrence Berkeley National Laboratory (Berkeley Lab) have reported the first fully integrated nanosystem for artificial photosynthesis. While 'artificial leaf' is the popular term for such a system, the key to this success was an 'artificial forest'.
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.
