As blood flows through these tiny capillaries oxygen diffuses from the blood into the surrounding tissue supplying them with the essential gas.
Oxygen diffuses from the gas compartment to the microfluidic channel allowing researchers to control how much oxygen cells are exposed to.
With Vindskiptm, he has designed a cargo ship that is powered by wind and gas. Software developed by Fraunhofer researchers will ensure an optimum use of the available wind energy at any time.
It has now been published in ature Communicationshollow Fibre Filled with Gasan infrared laser pulse is sent into a hollow fibre filled with gas.
The nonlinear interaction between the light and the gas atoms in the special fibre makes different wavelengths travel at different velocities.
they focused the pulse onto a target of xenon gas ionizing the xenon atoms. Depending on the exact shape of the laser pulse the electrons ripped away from the xenon atoms can be sent into different directions. t is an ultrafast electron switchsays Tadas Balciunas.
fill it with a useful gas, which is hydrogen. Unlike any of the other currently-available drones that can stay in the air for no more than 20 to 30 minutes at a time
In a clever design feature, the Hycopter stores 120 g of hydrogen gas at 350 bar (5, 075 psi) in its existing structural tubing no separate canister is required.
The lightweight lithium-polymer hybrid fuel cell that converts the hydrogen gas into electricity to power the rotors was developed by a sister company,

and drove a precise sampling pattern for more than eight hours just above a natural methane seep.
Natural methane seeps play an important but poorly understood role in the ocean ecosystem. The organisms that depend on methane from the seeps play a substantial role
not only in the marine food web but also in altering the quantity of methane released to the ocean surface and, potentially, in the overall chemistry of the ocean.
Scientists lack a clear understanding of how sedentary or slow-moving animals move between the widely separated seeps,
However, hydrogen is stored typically as a compressed gas in bulky high pressure tanks and these costly storage problems are a barrier to its use as a transport fuel of the future.
reater understanding of how the nanoscale structure of the storage material can influence gas storage capacities is expected to lead to more accurate evaluation methods for existing porous hydrogen storage materials.
Shift in focus These findings open the door to a shift in focus towards pore design with future research looking to exploit storing high density hydrogen in solid materials, rather than as a liquid or a gas q
virtually no methane emissions In addition to a near elimination of greenhouse gases associated with its growth, SUSIBA2 rice produces substantially more grains for a richer food source.
but it also the one of the largest manmade sources of atmospheric methane, a potent greenhouse gas.
Now, with the addition of a single gene, rice can be cultivated to emit virtually no methane from its paddies during growth.
With their warm, waterlogged soils, rice paddies contribute up to 17 percent of global methane emissions, the equivalent of about 100 million tons each year.
methane is about 20 times more effective at trapping heat. SUSIBA2 rice, as the new strain is dubbed,
low-methane rice that could offer a significant and sustainable solution. Researchers created SUSIBA2 rice by introducing a single gene from barley into common rice
resulting in a plant that can better feed its grains, stems and leaves while starving off methane-producing microbes in the soil.

resulting in even more methane emissions. It an issue that must be addressed. uring photosynthesis, carbon dioxide is absorbed
and convert it to methane. Researchers introduced SUSIBA2 into a common variety of rice and tested its performance against a non-modified version of the same strain.
Over three years of field studies in China, researchers consistently demonstrated that SUSIBA2 delivered increased crop yields and a near elimination of methane emissions f
such as a gas sensor, an optical switch, and even to reinforce composite materials to make them stronger.
In addition, late last year, it debuted a 6tb hard disk drive that apparently squeezed six 1tb platters without the need of helium gas like HGST-or any other exotic technologies.
The shift comes amid a downturn in the oil and gas industry as a whole: Oil prices are down to about half of their peak of $100-plus a barrel a year ago.
