ABSTRACT National and supranational institutions are establishing emission trading systems and control schemes in an attempt to manage stakeholders' willingness to engage with regulatory systems and reduce greenhouse gas emissions (GHG). Nonetheless, despite the national and supranational focus on carbon neutrality, little research has been centered ...

Carbon emission assessment of tunnel infrastructures: From construction to operation
This study develops a lifecycle carbon accounting framework for tunnel infrastructures, covering design, construction, operation, maintenance, and dismantling. Applied to a subsea tunnel case, the framework reveals the carbon emission distribution among four typical tunnel types and highlights potential carbon offset methods for low‐carbon tunnel ...

Observation of mesospheric air inside the arctic stratospheric polar vortex in early 2003 [PDF]
During several balloon flights inside the Arctic polar vortex in early 2003, unusual trace gas distributions were observed, which indicate a strong influence of mesospheric air in the stratosphere.

Experimental investigation of double layers in expanding plasmas
Double layers (DLs) have been observed in a plasma reactor composed of a source chamber attached to a larger expanding chamber. Positive ion beams generated across the DL were characterized in the low plasma potential region using retarding field energy ...

PtTe2 interface engineering for enhanced near‐infrared photoresponse in black silicon photodetectors
Highly responsive near‐infrared (NIR) photodetectors are essential for advanced photoelectric systems. In this work, a high‐responsivity NIR photodetector is developed by integrating a PtTe2/black silicon (B‐Si) heterostructure into a Si p‐i‐n diode, where B‐Si introduces sub‐bandgap defect states to enhance NIR absorption and the PtTe2 layer induces ...

Diffusion principles of SF6 tracer gas: constraints on SF6 mixing distance in mine tunnels
Mine wind measurement work is an important task to ensure the normal operation of mine production and environmental safety. The traditional wind measurement method uses the average wind speed and average cross-sectional area of the tunnel to calculate ...

Abstract Background Livestock, especially ruminants, are a major source of global methane emissions, primarily produced by methanogenic archaea during enteric fermentation. We performed a systematic review and meta‐analysis to account for factors that could influence the relationship between ruminal methanogenic populations and methane emissions, such ...

Almost all of modern gas insulated switchgears (GIS) use sulphur hexafluoride (SF6) as insulation material. Therefore, GIS quality much or less depends on quality of its SF6. Failure however can arise within operation of SF6 GIS due to quality decline of

Multipole response of doped $^3$He drops [PDF]
The multipole response of $^3$He$_N$ drops doped with very attractive impurities, such as a Xe atom or an SF$_6$ molecule, has been investigated in the framework of the Finite Range Density Functional Theory and the Random Phase Approximation.
