While efforts to involve the public in decision making on new technologies such as nanotechnology are impressive, they need to be substantially rethought, argues a new report from the EU-funded DEEPEN project.
Converting sunlight to electricity might no longer mean large panels of photovoltaic cells atop flat surfaces like roofs. Using zinc oxide nanostructures grown on optical fibers and coated with dye-sensitized solar cell materials, researchers have developed a new type of three-dimensional photovoltaic system. The approach could allow PV systems to be hidden from view and located away from traditional locations such as rooftops.
Next month in San Jose, CA, the AVS 56th International Symposium and Exhibition will showcase a spectrum of science and engineering research that is leading to breakthroughs in nanotechnology, alternative energy, materials research, and medicine - from fuel cells and batteries of the future to programmable materials and innovative approaches to drug design.
Duke University bioengineers have developed a simple and inexpensive method for loading cancer drug payloads into nano-scale delivery vehicles and demonstrated in animal models that this new nanoformulation can eliminate tumors after a single treatment.
A Spanish-US team of researchers has used a groundbreaking method to replicate the wings of butterflies and the colours of insects on a nanometric scale. The resulting technology has great potential to be used in a wide range of optical structures such as diffusers for solar panels or optical sensors.
The advances made in nanotechnology, particularly with respect to the biological and medical fields, are a testament to the herculean leaps made in nanotechnology in a short period of time, according to medical experts.
By analyzing data from the BNL Relativistic Heavy Ion Collider, the PHENIX collaboration at Brookhaven National Laboratory in Upton, USA, including scientists from the RIKEN BNL Research Center and the RIKEN Nishina Center for Accelerator-Based Science, has now ruled out gluons as the dominant contributor to proton spin.
Scientists at the University of Konstanz in Germany and the National Institute of Standards and Technology (NIST) in the United States have built the first optical frequency comb - a tool for precisely measuring different frequencies of visible light - that actually looks like a comb.
