Using their expertise in silicon optics, Cornell engineers have miniaturized a light source in the elusive mid-infrared (mid-IR) spectrum, effectively squeezing the capabilities of a large, tabletop laser onto a 1-millimeter silicon chip.
New findings represent the first evidence of an organism using mineralized structural components to produce optical displays. While birds, butterflies, and beetles can display brilliant blues, among other colors, they do so with organic structures, such as feathers, scales, and plates. The limpet, by contrast, produces its blue stripes through an interplay of inorganic, mineral structures, arranged in such a way as to reflect only blue light.
A European research project has made an important step towards the further miniaturisation of nanoelectronics, using a highly-promising new material called silicene. Its goal: to make devices of the future vastly more powerful and energy efficient.
By making what might be the world's smallest three-dimensional unofficial Block 'M', University of Michigan researchers have demonstrated a nanoparticle manufacturing process capable of producing multilayered, precise shapes.
A biological structure in mammalian eyes has inspired scientists to design an inorganic counterpart for use in solar cells: micron-sized vertical funnels were etched shoulder-to-shoulder in a silicon substrate. Using mathematical models and experiments, they tested how these kind of funnel arrays collect incident light and conduct it to the active layer of a silicon solar cell. Their result: this arrangement of funnels increases photo absorption by about 65 percent in a thin-film solar cell.
A new method will enable the fabrication of optical nanosensors capable of sticking on uneven surfaces and biological surfaces like human skin. This result can boost the use of wearable devices to monitor parameters such as temperature, breath and heart pressure.
Am 19. Februar 2015 hiess es wieder 'nANO meets water' bei Fraunhofer UMSICHT. Gut 100 Fachleute aus Industrie und Wirtschaft kamen nach Oberhausen, um sich beim Thema Innovationen und Risiken von Nanomaterialien für die Wassertechnik auf den neuesten Stand zu bringen.
