A low‐cost, automated, and adaptable system for field‐based measurement of pCO2, pCH4, and associated variables in groundwater

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract The Groundwater Automated Chemical Examiner (GrACE) is an automated analytical system of integrated sensors for the field‐based measurement of chemical and physical properties of groundwater. The GrACE system was designed to explore parameters influencing the dissolved concentrations of carbon dioxide (pCO2) and methane (pCH4) in groundwater ...

Evaluation of initial geostress field of underground powerhouse in the complex alteration area of western Sichuan based on back-propagation neural network method

open access: yesGeomechanics and Geophysics for Geo-Energy and Geo-Resources
Rock alteration leads to the degradation of the physical and mechanical properties of original rock. The spatial variance in the degree of rock alteration significantly influences regional ground stress distribution characteristics.

Using physics‐informed neural networks to quantify submarine groundwater discharge under high‐frequency tidal dynamics using heat as a tracer

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Estimating exchange rates of submarine groundwater discharge (SGD) at high temporal resolution over extended periods remains challenging, particularly when using heat as a tracer in highly dynamic environments such as tidal systems. Currently available heat transport models struggle to accurately quantify SGD exchange rates in these settings ...

Recent Developments in Sustainable Composites for Printed Circuit Boards (PCBs): A Review

open access: yesMacromolecular Materials and Engineering, EarlyView.
This review presents the potential of using natural plant fibers and biodegradable polymers as sustainable printed circuit boards (PCBs). This review provides future directions in innovation and sustainable PCBs development. Bio‐composites PCBs are both environmentally friendly and sustainable due to the natural fibres they contain.

Regenerative Polyphenolic Free‐Standing Conductive Film

open access: yesMacromolecular Materials and Engineering, EarlyView.
A rare combination of self‐assembly, spontaneous regeneration, and free‐standing form is achieved from initially non‐conductive polyphenol–amine complexes. The resulting films, assembled at the air/water interface and carbonized in one step, demonstrate flexibility, conductivity, and scalability.

Subsurface Investigations of Cryo‐Hydrogeological Features in a High Arctic Catchment Under Transition

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT In this study, the internal structure and seasonal variations of cryo‐hydrogeological features were investigated in the Fuglebekken catchment, located near the Polish Polar Station Hornsund in Svalbard. Over a few years, rising air temperatures and intensified water circulation have significantly altered the distribution, extent, and state of ...

Marine Anoxia and Ocean Acidification During the End‐Permian Extinction

open access: yesGeophysical Monograph Series, Page 325-340., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
