platinum

People looking to maintain their health have long been advised to take their minerals. Will trucks be doing the same thing? Maybe. A mineral made from the oxide family has been found to cut diesel-engine pollution by as much as 45 percent and may be able to replace the use of platinum as a ...

With over 20,000 Leafs running around the planet, Nissan is looking to introduce yet another alt-powered vehicle to the world, and judging by its recent work with fuel cells, a hydrogen-powered vehicle could be here in four year's time. Today in Japan, Nissan showed off its next-generation fuel ...

The UK's first public-access hydrogen fueling station – the one opened by Honda just days ago – dispenses hydrogen at 350 bar (5,076 psi) and 700 bar (10,153 psi). The reason is that these are the two standard filling pressures adopted by the world's major automakers, and it requires ...

In a recent paper published in Science, a group of researchers has theorized that a non–precious metal catalyst, with performance that's claimed to be comparable to platinum-based systems, could some day end up in automotive fuel cells. Los Alamos National Laboratory researchers Gang Wu, ...

U.S. Department of Energy's Brookhaven National Laboratory has got a few interesting projects going on right now that may be of interest to our readers. First is a project headed by chemist James Muckerman where the "goal is to design a bio-inspired system that can produce fuels like methanol or ...

I don't know nearly enough about the mining of precious metals such as platinum to estimate how much it costs to get a reasonable amount from the earth. But, I do know that the metal is expensive to buy, so it must at least be reasonably difficult, right? So, perhaps we should be looking at ...

Gold, ah yes. The precious metal that adorns the majority of the population of the United States and other countries. We like it because of it's looks and the fact that it is rare. Which makes it expensive, unfortunately. But, not as expensive as platinum, another precious metal that is ...

When I first heard about this type of theft a couple months ago, I thought it was an isolated incident. But in the last month I've found reports from Florida, Louisana, Tennessee and Michigan of similar actions: thieves are cutting out the catalytic converters on late-model vehicles to get at the ...

One of the drivers of the high cost of fuel cells right now is the need for platinum as a catalyst material. At the current price of just shy of $1,100 per ounce, the 100g of platinum required by a 100kW fuel cell accounts for about $3,500 of the cost. Researchers at the Tokyo University of ...

Yesterday, PhysOrg reported on the recently published fuel cell research of two Los Alamos scientists, Rajesh Bashyam and Piotr Zelenay, in the scientific journal Nature. Searching for a low-cost alternative to platinum, the duo developed a composite consisting of cobalt, polymer and carbon. The ...
