Wearable photovoltaic textiles: From device technologies to long‐term reliability

InfoScience, EarlyView.
Wearable photovoltaic textiles are highlighted as reliable energy sources that combine solar cell efficiency with hierarchical textile‐specific mechanical and environmental durability. Structural and encapsulation strategies, including planarization, neutral‐axis engineering, and advanced barrier designs, enable waterproofing, washability, UV shielding,

Electrical resistivity tomography (ERT) of a coastal carbonate aquifer (Port-Miou, SE France) [PDF]

Environmental Earth Sciences, 2013
As part of a larger regional research program “KarstEAU”, the authors have applied electrical resistivity tomography (ERT) techniques to characterize heterogeneities in the Port-Miou coastal karst aquifer (Cassis, SE France). Field surveys were carried out on intensely fractured and karstified Urgonian carbonates.

Dissolution-enlarged fractures imaging using electrical resistivity tomography (ERT) [PDF]

, 2017
In recent years the electrical imaging techniques have been largely applied to geotechnical and environmental investigations. These techniques have proven to be the best geophysical methods for site investigations in karst terrain, particularly when the ...

Recovery from electrode position uncertainties in geophysical electrical resistance tomography – Application to moisture transport imaging

Near Surface Geophysics, EarlyView.
Abstract In studies of subsurface hydrology, monitoring and imaging techniques are used to estimate the moisture content, or to track moisture or injected tracer movement. One applied imaging technique is electrical resistance tomography (ERT), in which measurements collected using electrodes placed on the ground surface or in boreholes are used to ...

Within‐tree spatial heterogeneity of sap flow velocities and wood properties and its effect on the uncertainty of tree level sap flux estimates

PLANTS, PEOPLE, PLANET, EarlyView.
As forests are important for biodiversity and recreation and provide vital resources globally, it is essential that their health can be accurately monitored, for example, by using sap flow probes to measure tree water uptake. We investigated whether sap flow measurements might differ at various locations within the same tree due to variation in wood ...

Using Electrical Resistivity Tomography (ERT) as a tool in geotechnical investigation of the substrate of a highway

Studia Quaternaria, 2014
Abstract Geological and geotechnical engineering field tests, like structure drillings and dynamic (DPL, DPSH) or static probing (CPT), are considered for a fundamental source of information about soil and water environments. Since Eurocode 7 has been introduced, it has become more common to use also dilatometers (DMT) or pressure meters (PMT ...

Identification of leachate infiltration and its flow pathway in landfill by means of electrical resistivity tomography (ERT)

Environmental Monitoring and Assessment, 2020
Sanitary landfills are a well-planned engineering work for final disposal of municipal solid waste in order to minimize the environmental impacts in soil and groundwater. Therefore, several control systems are installed such as liners and leachate and biogas collectors.
