An international research team, including Professor Rajeev Ahuja's research group at Uppsala University, has shown that small additions of potassium drastically improve the hydrogen-storage properties of certain types of hydrogen compounds. The findings are published in the Web edition of Angewandte Chemie International Edition."Our energy-consuming world has become more and more dependent on new methods of storing and converting energy for new, environmentally friendly means of...

U.S. scientists say they've created a hydrogen storage system that allows a car's fuel tank to be filled within five minutes for a 300-mile driving range. Purdue University researchers said their system uses metal hydride powder to absorb hydrogen gas. The researchers have created a heat exchanger that circulates coolant through tubes and uses fins to remove heat generated as the hydrogen is absorbed by the powder. Professor Issam Mudawar, who led the project that was funded by the General...

A team of scientists from Virginia Commonwealth University, the University of Uppsala in Sweden, and the Savannah River National Laboratory have identified that carbon nanostructures can be used as catalysts to store and release hydrogen, a finding that may point researchers toward developing the right material for hydrogen storage for use in cars. Scientific findings indicate that hydrogen has all the makings of an ideal alternative fuel because it is clean, renewable and abundant, but there...

By Nakajima, Hideo Ide, Takuya Lotus-type porous copper with aligned long cylindrical pores was fabricated by unidirectional solidification in an argon atmosphere. The hydrogen dissolved in molten copper through thermal decomposition of titanium hydride contained in the mold, which then formed hydrogen gas that evolved into the gas pores in the solidified copper. On the other hand, titanium may form oxides in the melt that serve as nucleation sites for insoluble hydrogen. The porosity and...

Environmentally friendly hydrogen gas fueled vehicles can dramatically reduce greenhouse gas emissions and lessen the country's dependence on sources of fossil fuel. Though several hydrogen vehicles exist on the market today, there is still much room for improvement in the way that hydrogen is stored on-board the vehicle. With current technologies, hydrogen gas storage tanks have to be as large as or larger than the trunk of a car to carry enough gas to travel only one to two hundred miles....

A new rubber-like material created with the ability to "heal" itself is paving the way for the development of a wide variety of new products.Polymer chemist Ludwik Leibler developed the "supramolecular rubber" with his colleagues at the Industrial Physics and Chemistry Higher Educational Institution (ESPCI) in Paris, France.When light pressure is applied to the fractured pieces of rubber at room temperature, they form a hydrogen bond and about 15 minutes later become one piece that is just as...

Researchers have synthesized a new class of aluminum-hydrogen compounds with a unique chemistry that could lead to the development of more powerful solid rocket fuel and may also, in time, be useful for hydrogen-powered vehicles or other energy applications. An article about this research, led by scientists at the Johns Hopkins and Virginia Commonwealth universities, is published in the Jan. 19 issue of the journal Science. The team also included scientists at University of Konstanz and...

A research team from the Public University of Navarra has started a study of the design and development of absorbent materials that enable the storage of hydrogen, a clean fuel that can be used as an alternative to those derived from fossil fuels, such as petrol and diesel. The storage of this element is, in fact, a key process in the change over from internal combustion engines "“ contaminating and not very efficient, to cars with hydrogen fuel cells. The project, entitled, Development...

Aluminum (or aluminium) is a soft, lightweight, silvery metal. It is an element in the boron group on the periodic table of elements, with the symbol Al and atomic number 13. On the earth's crust, aluminum is the most abundant metal, and the third most abundant of all elements on the earth's crust, after oxygen and silicon. It accounts for 8% of the weight of the Earth's solid surface. Because aluminum is a highly reactive metal, it doesn't occur in nature in a pure form. Aluminum forms a...

Lithium is the chemical element with symbol Li and atomic number 3. In the periodic table, it is located in group 1, among the alkali metals. Lithium in its pure form is a soft, silver white metal, that tarnishes and oxidizes very rapidly in air and water. It is the lightest solid element and is primarily used in heat transfer alloys, in batteries and serves as a component in some drugs known as mood stabilizers. Notable characteristics Lithium is the lightest metal and has a density...
