Sentences with phrase «gas at high densities»

«We have come up with a material that mechanically traps gas at high densities without having to use high pressures, which require special storage tanks and generate safety concerns,» said George Shimizu, the lead scientist on the study, which was published in Nature - Materials.

Finding materials able to store the gas at high densities and in small, lightweight tanks has been a tremendous challenge; Ozolins and his colleagues hope their work will facilitate this breakthrough in the next few years.

Not exact matches

At Battelle, Koper is studying the use of nanomaterials in membranes for water desalination and treatment; supercapacitors (energy - storage devices that provide higher power densities than batteries); and bio-based (rather than petroleum - based) additives used for hydraulic fracturing, or fracking, to retrieve natural gas.

But this was just what we wanted — something that looked just like a gas, but at higher density.»

The Baryon Oscillation Spectroscopic Survey (BOSS), the largest component of the third Sloan Digital Sky Survey (SDSS - III), pioneered the use of quasars to map density variations in intergalactic gas at high redshifts, tracing the structure of the young universe.

The density - wave theory, proposed by Frank Shu and C.C. Lin in 1964, says that a galaxy's spiral pattern is a wave of higher density, or compression, that revolves around the galaxy at a speed different from that of the galaxy's gas and stars.

An international research team led by Takuma Izumi, a second - year master's student of science at the University of Tokyo, and Kotaro Kohno, a professor at the University of Tokyo, successfully captured a detailed image of high - density molecular gas around an active supermassive black hole at the center of a galaxy called NGC 1097 at the highest sensitivity ever achieved.

Using 12CO lines to trace molecular gas at both low and high densities, a new map depicts a high signal - to - noise image of the inner part of IC342 that includes the first spiral arm.

The observations made possible by the band 9 receivers allow astronomers to study molecular clouds — the dense regions of gas and dust where new stars are being born — at higher temperatures and densities, and with higher angular resolution, thus complementing the longer wavelength bands.

A high - efficiency exhaust system and the dual - bed, high - density catalytic converter help the Accord engine meet stringent LEV3 - AT - PZEV (SULEV30) / Interim Tier3 Bin30 standards, which require reduced greenhouse gases compared to lower standards.

A high - efficiency exhaust system and the dual bed, high - density catalytic converter help the Accord engine meet stringent LEV3 - AT - PZEV (SULEV30) / Interim Tier3 Bin30 standards, which require reduced greenhouse gases compared to lower standards.

A huge laser delivers a large amount of energy in a short time to heat the walls of the larger chamber, and the radiation emitted from those walls in turn drives the small capsule to a very small size, increasing the density of the gases inside to much higher density than lead and heating it at the same time to very high temperatures required for fusion to occur.

Higher density sources of fuel such as coal and natural gas utilized in centrally - produced power stations actually improve the environmental footprint of the poorest nations while at the same time lifting people from the scourge of poverty... Developing countries in Asia already burn more than twice the coal that North America does, and that discrepancy will continue to expand... So, downward adjustments to North American coal use will have virtually no effect on global CO2 emissions (or the climate), no matter how sensitive one thinks the climate system might be to the extra CO2 we are putting back into the atmosphere.

So it's all gases at greatest density will be doing the same thing around the planet at the same time (*) and as these change with differences in density in the play between gravity and pressure and kinetic and potential from greatest near the surface to more rarified, less dense and absent any kinetic to write home about the higher one goes, then, energy conservation intact, the hotter will rise and cool because losing kinetic energy means losing temperature, thus cooling they which began with the closest in density and kinetic energy as a sort of band of brothers near the surface will rise and cool at the same time whereupon they'll all come down together colder but wiser that great heights don't make for more comfort and giving up their heat will sink displacing the hotter now in their place when they first went travelling.

When dipped into a beaker of water, instead of producing electricity, the leaf harnessed the electrons to break the chemical bonds of water and release hydrogen gas — a fuel that can store energy at a significantly higher density and lower cost than electricity.

We assumed only that due to the biological and physical effects the ratio fabsorbed (t) / (total CO2 content of then air) is more or less constant, hence a simple response pulse response exp -LRB-- t / lifetime) is applied to the anthropic time series of coal, gas, oil and cement which have different delta13C As the isotopic signature of (CO2 natural)(t) is slowly decreasing because plants living days or centuries ago are now rotting and degassing and as molecules entered in the ocean decades ago are now in the upwellings after a slow migration along the equal density surface from the high latitudes where those surface are surfacing at depth zero, there are common sense constraints or bounds on the possible evolution of the delta13C of the natural out - gassed CO2 molecules.

To their surprise, the titanium augmented sodium alanate's capabilities as a storage system - lowering the temperature at which hydrogen was released, making the process much more efficient, while allowing for easier refueling and storage of high - density hydrogen at more conventional pressures and temperatures.The result: a near - doubling of the stored gas» weight - percent when compared to other cheap materials.
