Recent Advances in Laser‐Induced Graphene‐Based Gas Sensors: From Sensing Mechanisms to Biomedical Applications

Advanced Science, EarlyView.
Laser‐induced graphene (LIG) provides a scalable, laser‐direct‐written route to porous graphene architecture with tunable chemistry and defect density. Through heterojunction engineering, catalytic functionalization, and intrinsic self‐heating, LIG achieves highly sensitive and selective detection of NOX, NH3, H2, and humidity, supporting next ...

Integration of on-farm biodiesel production with anaerobic digestion to maximise energy yield and greenhouse gas savings from process and farm residues

, 2011
Anaerobic co-digestion of residues from the cold pressing and trans-esterification of oilseed rape (OSR) with other farm wastes was considered as a means of enhancing the sustainability of on-farm biodiesel production.

Characterization of carbon monoxide, methane and nonmethane hydrocarbons in emerging cities of Saudi Arabia and Pakistan and in Singapore [PDF]

, 2016
We investigate the composition of 63 C2-C10 nonmethane hydrocarbons (NMHCs), methane (CH4) and carbon monoxide (CO), in Jeddah, Mecca, and Madina (Saudi Arabia), in Lahore, (Pakistan), and in Singapore. We established a database with which to compare and

Liquid Bismuth Catalyst Enables High‐CO‐Selectivity in CO2 Hydrogenation

Advanced Science, EarlyView.
This work introduces a dynamic liquid bismuth catalyst for efficient CO2‐to‐syngas conversion. Stabilized molten Bi nanodroplets on a defective VOx support enable a reversible Bi3+/Bi0 redox cycle at moderate temperatures. Mechanistic insights reveal that Ni‐Bi dual sites synergistically activate H2 and cleave CO2, leading to high CO selectivity ...

Basal Plane Activation of SnS2 Thin‐Film by Fluorine Doping for Selective Solar‐Driven CO2 Reduction With Enhanced Quantum Efficiency

Advanced Science, EarlyView.
The synergistic effect of fluorine doping and sulfur vacancies boosts the activity of the active sites without active‐site modulation, leading to enhanced CO2 photoreduction efficiency and a selectivity switch from CH4 to CO on tin disulfide continuous thin films. ABSTRACT Photocatalytic conversion of CO2 into value‐added fuels offers a viable approach

Mutual Dependence between Sustainable Energy- and Sustainable Agriculture Policies-from the Global and European Perspective [PDF]

, 2012
Agriculture is one of the economic sectors to which the EU commitment to reduce emissions of greenhouse gases applies. Like any other economic sector, agriculture produces greenhouse gases and is a major source of the non- CO2 greenhouse gases methane ...

Efficient and Robust Heterostructure CeZrOx/NiO‐Ni Inverse Catalyst for Sustainable Photothermal CO2 Methanation

Advanced Science, EarlyView.
A heterostructured CeZrOx/NiO‐Ni inverse catalyst is designed for highly efficient photothermal CO2 methanation under low‐intensity light without auxiliary heating. It achieves 464 mmol·gcat−1·h−1 methane space‐time yield under natural concentrated sunlight, maintains stability over light‐dark cycles and extended air storage, and is scalable to 100 g ...

Oxidation is a potentially significant methane sink in land-terminating glacial runoff

Scientific Reports
Globally, aquatic ecosystems are one of the largest but most uncertain sources of methane, a potent greenhouse gas. It is unclear how climate change will affect methane emissions, but recent work suggests that glacial systems, which are melting faster ...
