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.
Newly developed tiny antennas, likened to spotlights on the nanoscale, offer the potential to measure food safety, identify pollutants in the air and even quickly diagnose and treat cancer, according to the scientists who created them.
Designing or exploring new materials is all about controlling their properties. In a new study, scientists offer insight on how different 'knobs' can change material properties in ways that were previously unexplored or misunderstood.
The goal of the European NanoMend project is to develop new technologies for the detection, cleaning and repair of micro and nanoscale defects in thin films that are vital in products such as printed electronics and solar panels.
In an open-access paper, more than 60 academics and industrialists lay out a science and technology roadmap for graphene, related two-dimensional crystals, other 2D materials, and hybrid systems based on a combination of different 2D crystals and other nanomaterials.
Researchers have created a variety of nanostructures that can modify the electronic properties of graphene, either by periodic modulation of the electrostatic potential, or by periodic mechanical stress that can generate an effective magnetic structure.
