Not exact matches

Resistance is also fueled by the massive and often inappropriate use of antibiotics in agriculture; for decades these precious drugs have been used to promote growth and fend off costly infections that can result from the cramped conditions of industrial - scale food animal production.

Cars running on hydrogen fuel cells produce zero emissions, but currently, factories must use fossil fuels, such as natural gas, or precious metals, such as platinum, to...

«Armed with this new understanding, practitioners will be able to design catalysts using just the necessary amount of the precious metals like gold and platinum, dramatically cutting down the catalyst cost in fuels and chemicals production processes,» she adds.

Precious metals have long been used as conducting materials in batteries and other types of fuel cells but are too expensive to use at a commercial scale in microbial fuel cells.

Many commercial catalysts for fuel cells contain the precious metal platinum, which aside from being expensive, is too rare to support ubiquitous use in vehicles.

The device could make hydrogen cars affordable for many more consumers because it produces hydrogen using nickel, iron and cobalt — elements that are much more abundant and less expensive than the platinum and other precious metals that are currently used to produce hydrogen fuel.

This square is a biofuel cell that sticks to the skin and contains sweat - fuelled enzymes that replace the precious metals normally used in batteries (Energy and Environmental Science, doi.org/b8xh).

Other flow batteries contain precious metal electrocatalysts such as the platinum used in fuel cells.

It turns out that there's such a double - win in most bathrooms around the world; if we had «NoMix» toilets that separate urine from solid waste, municipal wastewater plants would have a significantly easier task (and produce more methane to generate electricity), and we could much more easily extract precious nutrients like phosphorus and nitrogen for use as fertilizer (instead of using fossil fuels).

Researchers use materials free of precious metals to speed the troubling side of the fuel cell reaction

Led by Yuehe Lin, professor in the School of Mechanical and Materials Engineering, the researchers used inexpensive metal to make a super low density material, called an aerogel, to reduce the amount of precious metals required for fuel cell reactions.

Initially, Planetary Resources will focus not upon precious metals, but easier - to - find resources such as water, oxygen, hydrogen and materials that can be used as fuel.

While it is possible to explore Ceres completely using only these jets, mission managers want to conserve precious fuel.

precious metals (like gold, platinum and palladium), a variety of which can be recycled into component plating and low voltage electrical contacts; palladium plays a key role in the technology used for fuel cells.

Fossil fuels have many alternative uses that do not involve dumping carbon pollution into the atmosphere, such as petrochemicals, and should be used far more wisely if indeed we consider them to be precious — so that we save the climate, oceans and air pollution and don't scrape the barrel dry.

The device could make hydrogen cars affordable for many more consumers because it produces hydrogen using nickel, iron and cobalt — elements that are much more abundant and less expensive than the platinum and other precious metals that are currently used to produce hydrogen fuel.

Using precious water and soil resources to grow bio fuels makes little or no sense and is not a solution to anything.

Replacing fossil fuel technologies with fuel cells that use precious metals is unsustainable.

«This could allow us, for example, to replace the precious metal catalysts currently used in many solar - fuel generator prototypes with catalysts made from earth - abundant elements.»
