Membrane Gas Desorption (MGD), Low temperature separation (LT) and the High temperature membrane air separation (ITM. The main finding was that the LT technology was the most economic,
The predicted results include both the pyrolysis process of individual particles and the tar concentration in the gas as a response to the interaction between hot air and wood particles.
As reported in the journal Water Research Gao ground wood chips that were heated then in nitrogen gas but not burned.
Organophosphates are found in everything from industrial pesticides to the sarin gas used in chemical warfare. They permanently bond to neurotransmitters in the brain,
which could prevent nerve damage in the event of a gas attack or pesticide exposure and would likely be developed first for military use,
As reported in the journal Water Research Gao ground wood chips that were heated then in nitrogen gas but not burned.
A metal bellows about the size of a cantaloupe is filled with a temperature-sensitive gas.
When the gas heats and cools in response to the outside air temperature it expands and contracts causing the bellows to do the same.
The hydrogen gas could power fuel cells in zero emissions vehicles. The battery sends an electric current through two electrodes that split liquid water into hydrogen and oxygen gas.
Unlike other water splitters that use precious-metal catalysts the electrodes in the Stanford device are made of inexpensive and abundant nickel
or iridium to achieve that voltage. n addition to producing hydrogen the new water splitter could be used to make chlorine gas and sodium hydroxide an important industrial chemical according to Dai.
A fuel cell combines stored hydrogen gas with oxygen from the air to produce electricity which powers the car.
and enable the economic production of gas resources with higher carbon dioxide content that would be too costly to recover using current carbon capture technologies says James Tour professor of mechanical engineering and nanoengineering and of computer science at Rice university.

#A new way to detect leaks in pipes Explosions caused by leaking gas pipes under city streets have made frequently headlines in recent years,
In addition to their potential for dangerous explosions, leaking gas pipes can be a significant contributor to global warming:
and should be effective in gas, water, and oil pipes. MIT mechanical engineering professor Kamal Youcef-Toumi, a co-author of the research papers,
they also modified plants to detect the gas nitric oxide. Together these represent the first steps in launching a scientific field the researchers have dubbed lant nanobionics. lants are very attractive as a technology platform,
Lean green machines The researchers also showed that they could turn Arabidopsis thaliana plants into chemical sensors by delivering carbon nanotubes that detect the gas nitric oxide,
and exposed to sunlight produces hydrogen gas. The scientists say that the technique could allow their technology to be scaled up at low cost.
Scaling this research up in the future may mean that you could replace the gas in your cars and generators with hydrogen greener option,
we were able to demonstrate an energy-rich biologically-inspired alternative to gas.""This research,"Photoinduced Electron Transfer pathways in Hydrogen-Evolving Reduced graphene oxide-Boosted Hybrid Nano-Bio Catalyst,

The current prototype is quieter than a neighbor mowing the lawn with a gas-powered motor."
These findings could one day lead to super-dense low-power circuits as well as ultra-sensitive biosensors and gas sensors, the investigators added.

which reacts with the inner platinum surface of the micromotors to generate a stream of oxygen gas bubbles that propel the micromotors around.
The reaction also yields excess hydrogen gas, which can be stored and harnessed as energy in a fuel cell.
in which the liquid partially floats on a layer of air or gas, and Wenzel, in which the droplets are in full contact with the surface,
Bacteria decompose the mixture and produce among others the energy-rich gas of methane. It is used then for the gas stoves in the kitchen of the hospital.
Via a pipeline system the gas is passed directly on to the gas stoves of the neighboring houses.

"This was a milestone for trace-gas sensing, "Ren said.""Now we're trying to minimize the size of the whole system."
The scientists can use gas-based samples rather than high concentrations in solution and the technique is much more detailed by looking at energies involved scientists can see many other things about the molecule,
and solar power in recent years is launching more than 20 demonstration projects that involve storing energy by splitting water into hydrogen gas and oxygen.

Current carbon capture technology uses caustic amine-based solvents to separate CO2 from the flue gas escaping a facility's smokestacks.
This innovative gas separation platform provides large surface areas while eliminating a number of operational issues including corrosion evaporative losses
