Implications of heterogeneous embankment conditions for geoelectrical investigations on dams: A case study at Mactaquac Dam, Canada

Near Surface Geophysics, EarlyView.
Abstract Electrical resistivity tomography (ERT) has been shown to be effective for surveying and monitoring dams, due to the method's sensitivity to moisture content and relevant physical properties (e.g., porosity). Automated ERT systems, capable of time‐lapse monitoring, can be used to detect variations in ground conditions.

Evaluating the sustainability of mineral water consumption using multi‐scale hydrogeophysics in Caxambu, Brazil

Near Surface Geophysics, EarlyView.
Abstract A better understanding of the near‐surface aquifer system of the Caxambu Water Park, located in the Minas Gerais State, Brazil, has been achieved. The study aimed to identify groundwater reservoirs and flow patterns and contribute to the hydrogeological conceptual model using a multi‐scale geophysical approach.

Impact and Post‐Impact Properties of Carbon Fiber Fabric Laminates Reinforced With Carbon Nanofibres

Polymer Composites, EarlyView.
Carbon nanofiber addition on the low‐velocity impact response of carbon fiber laminates. ABSTRACT The use of carbon fiber reinforced polymers (CFRPs) is limited by their susceptibility to low‐velocity impact (LVI) damage. This study investigates the effect of incorporating 0.75 wt.% carbon nanofibres (CNFs) into the epoxy matrix of carbon fiber fabric ...

Using Lignin and Spent Coffee Grounds as Bio‐Additives in 3D‐Printable Poly Lactic Acid/Multi‐Walled Carbon Nanotube Composites for Advanced Electronic Applications

Polymer Composites, EarlyView.
Bio‐based additives derived from lignin and spent coffee grounds (SCG) are used to enhance MWCNT dispersion in PLA composites, enabling improved electrical conductivity and reliable in material extruded strain‐gauge sensors. ABSTRACT In this work, three bio‐based additives, lignin, spent coffee grounds (SCG), and oil extracted from SCG (Ox‐SCG) were ...

Failure Mechanisms of Short Fiber Reinforced Composite Materials Subjected to Dynamic Loading

Polymer Composites, EarlyView.
Failure Mechanisms of Short Fiber Reinforced Composite Materials Subjected to Dynamic Loading. ABSTRACT The mechanical behavior of short carbon fiber reinforced polylactic acid (SCF/PLA) composites fabricated by fused deposition modeling (FDM) is crucial for engineering applications, yet their strain‐rate dependence is not fully understood.
