Warming up the world of superconductors
A superconductor that works at room temperature was long thought impossible, but scientists may have discovered a family of materials that could make it reality.
Silicon micro-funnels increase the efficiency of solar cells
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.
In quest for better lithium-air batteries, nanoparticle coatings improve carbon's stability
Researchers unveiled a new method of stabilizing carbon - a central structural component of any battery - that could pave the way to new performance standards in the hunt for a lithium-ion components.
Magnetic nanoparticles enhance performance of solar cells
Magnetic nanoparticles can increase the performance of solar cells made from polymers - provided the mix is right.
Flexible nanosensors for wearable devices
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.
Graphene shows potential as novel anti-cancer therapeutic strategy
Scientists have used graphene to target and neutralise cancer stem cells while not harming other cells.
nANO meets water VI: Nanotechnik für die Wasser-Praxis
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.
New nanowire structure absorbs light efficiently
Dual-type nanowire arrays can be used in applications such as LEDs and solar cells.
