Dynamics of methane ebullition from a peat monolith revealed from a dynamic flux chamber system [PDF]

, 2014
Methane (CH4) ebullition in northern peatlands is poorly quantified in part due to its high spatiotemporal variability. In this study, a dynamic flux chamber (DFC) system was used to continuously measure CH4 fluxes from a monolith of near‐surface ...

Widespread dominance of methane ebullition over diffusion in freshwater aquaculture ponds

Frontiers in Water, 2023
An ever-increasing demand for protein-rich food sources combined with dwindling wild fish stocks has caused the aquaculture sector to boom in the last two decades.

Warming Effect from Soil Greenhouse Gas Emission of Each Mangrove Zone during the Dry Season in Ngurah Rai Forest Park, Bali, Indonesia

Environment and Natural Resources Journal
In addition to functioning as a carbon sink, mangrove soil also releases greenhouse gases (GHGs) through microbial metabolism. GHG flux fluctuates according to the ecological parameters of mangroves and climate variability.

Suppression of methane uptake by precipitation pulses and long-term nitrogen addition in a semi-arid meadow steppe in northeast China

Frontiers in Plant Science, 2023
In the context of global change, the frequency of precipitation pulses is expected to decrease while nitrogen (N) addition is expected to increase, which will have a crucial effect on soil C cycling processes as well as methane (CH4) fluxes.

On the escape of CH4 from Pluto's atmosphere

, 2015
We adapted a multi-species escape model, developed for close-in extrasolar planets, to calculate the escape rates of CH4 and N2 from Pluto. In the absence of escape, CH4 should overtake N2 as the dominant species below the exobase.

Energy input is primary controller of methane bubbling in subarctic lakes [PDF]

, 2014
Emission of methane (CH4) from surface waters is often dominated by ebullition (bubbling), a transport mode with high‐spatiotemporal variability. Based on new and extensive CH4 ebullition data, we demonstrate striking correlations (r2 between 0.92 and 0 ...

Impact of Sustainable Binders Based on Lignin and Collagen on the Volume Stability and Mechanical Properties of MgO‐C Refractories with MgO‐C Recyclates

Advanced Engineering Materials, EarlyView.
Collagen hydrolysate is evaluated as a sustainable binder for MgO‐C refractories. Its thermally induced cross‐linking and gas release lead to expansion and cracking in large bricks, but tailored batches with lignin, recyclates, or fine graphite improve the gas release while thermal treatment and stability.

Carbon dioxide and methane emission rates from taxi vehicles in Thailand

Carbon Management, 2018
Due to the expansion of urban areas have been increasing levels of greenhouse gas emissions from taxi and passenger cars that use natural gas for vehicles (NGV) and liquid petroleum gas (LPG) as alternative fuels .

Ideal Molecular Sieving with a Dense MOF for Helium Upgrading with Highly Diffusion Selective Mixed Matrix Membranes

Advanced Functional Materials, EarlyView.
The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.
