Researchers develop highly efficient hollow copper electrodes
Scientists at the University of Twente research institute MESA+ have developed an electrode in the form of a hollow porous copper fibre which is able to convert CO2 into CO extremely efficiently. In principle the invention enables a wide variety of industrial processes, for example in the steel industry, to be made more sustainable. The researchers have applied for a patent on their invention, and their research results have been published in the...
'Keiser rigs' stress materials to improve products
Understanding and predicting the performance of cutting-edge materials in extreme environments have long been signature strengths at the Department of Energy's Oak Ridge National Laboratory. For decades, environmental exposure chambers at ORNL, including some called Keiser rigs, have subjected materials to corrosive gases, crushing pressures and calamitous heat.
Miniaturised fuel cell makes drones fly for longer
Drones are used for various applications such as aero picturing, disaster recovery, and delivering. Despite attracting attention as a new growth area, the biggest problem of drones is its small battery capacity and limited flight time of less than an hour. A fuel cell developed by Prof. Gyeong Man Choi (Dept. of Materials Science and Engineering) and his research team at POSTECH can solve this problem.
Nanoscale rotor and gripper push DNA origami to its limits
Scientists at the Technical University of Munich (TUM) have built two new nanoscale machines with moving parts, using DNA as a programmable, self-assembling construction material. In the journal Science Advances, they describe a rotor mechanism formed from interlocking 3-D DNA components. Another recent paper, in Nature Nanotechnology, reported a hinged molecular manipulator, also made from DNA. These are just the latest steps in a campaign to tr...
Material increases the lifetime of solar-powered electrons
Storing sunlight as fuel that can be later used to drive fuel cells requires new materials. Scientists demonstrated such a material. They combined two oxides on the atomic scale. The interface between the oxide materials, one containing strontium and titanium (SrTiO3) and one containing lanthanum and chromium (LaCrO3), absorbs visible light, producing electrons and holes that might be useful for catalysing reactions, such as producing hydrogen fu...
Molecular architectures see the light
Organic photovoltaics bear great potential for large-scale, cost-effective solar power generation. One challenge to be surmounted is the poor ordering of the thin layers on top of the electrodes. Utilising self-assembly on atomically flat, transparent substrates, a team of scientists at the TUM has engineered ordered monolayers of molecular networks with photovoltaic responses. The findings open up intriguing possibilities for the bottom-up fabri...
Tanaka to exhibit at FC EXPO 2016
Tanaka Precious Metals will exhibit at "FC EXPO 2016 - 12th International Hydrogen and Fuel Cell Expo," one of the world's largest fuel cell exhibitions, which will be held at Tokyo Big Sight from Wednesday, March 2 until Friday, March 4, 2016.
Engineers use rust to build a solar-powered battery
A team led by William Chueh, an assistant professor of materials science and engineering, and Nicholas Melosh, an associate professor in the same department, has made a discovery that could make large-scale solar power storage a reality. The breakthrough is based on the fact that ordinary metal oxides, such as rust, can be fashioned into solar cells capable of splitting water into hydrogen and oxygen.
Hydrogen fuel cells to power drones
CES showstopper Intelligent Energy has signed a Letter of Intent (LOI) with a major drone manufacturer to develop hydrogen fuel cell powered drones. The deal will see the two companies work together in the first quarter of 2016 to develop technological solutions to increase drone flight time. The goal is for the deal to lead to a formal commercial arrangement for the solutions’ rollout.
Fuel cells powering inner-city vehicles
Inner-city deliveries in Austria may soon be powered by pollution-free fuel cell technology that is also being explored by ESA for satellites and robotic missions to Mars. Austrian transport specialist HET Engineering has designed a quiet, zero-emission vehicle for sensitive traffic areas. With technical assistance from the DLR German Aerospace Center, the company's Citylog EMF vehicles will be small enough to navigate narrow and congested street...
