New scanning technology which will give a much clearer picture of lung disease has taken a major step forward thanks to scientists at The University of Nottingham. The experts at the Sir Peter Mansfield Imaging Centre have developed a process using specially treated krypton gas as an inhalable contrast agent to make the spaces inside the lungs show up on an MRI scan. It's hoped the new process will eventually allow doctors to virtually see inside...

Research teams separated by 14 hours and 9,000 miles have collaborated to advance prospective treatment for the world's second-leading cause of death.University of Nebraska-Lincoln chemists partnered with medical researchers from the National University of Singapore to develop a molecule that can inhibit an enzyme linked with the onset of stroke.

Stanford scientists have discovered a novel way to make plastic from CO2 and inedible plant material, such as agricultural waste and grasses. Researchers say the new technology could provide a low-carbon alternative to plastic bottles and other items currently made from petroleum. "Our goal is to replace petroleum-derived products with plastic made from CO2," said Matthew Kanan, an assistant professor of chemistry at Stanford.

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...

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.

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.

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...

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...

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 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.
