Borophene and Its Composite‐Based Electrochemical Sensors

ChemElectroChem, EarlyView.
Borophene shows promising potential in electrochemical sensors and biosensors due to its unique properties. A composite of borophene and conducting polymers demonstrate remarkable sensing capabilities in detecting dopamine and glucose. By utilizing the advantages of electrochemical sensors, the boron‐based electrochemoresistance sensor improves its ...

First field application of temperature sensor modules for groundwater flow detection near borehole heat exchanger

Geothermal Energy, 2019
Here, we present the first application of a temperature sensor module (TSM) for deducing groundwater flow velocity and direction at borehole heat exchangers (BHEs). The TSM maps the horizontal temperature distribution around a BHE.

Weighing risks against GHG reduction benefits in emerging green technologies

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Green technologies represent promising strategies for mitigating carbon emissions and combating global warming. However, their implementation in civil and industrial applications is not without risks, as intrinsic uncertainties and latent safety concerns can threaten their effective deployment.

Review of recent advances in the design, synthesis, and modification of biochar for remediation of heavy metal pollution in water

The Canadian Journal of Chemical Engineering, EarlyView.
Research frontiers in using biochar for heavy metal remediation. Abstract Heavy metal contamination of water has long been a serious environmental issue. Biochar and biochar‐based composites are emerging as effective and sustainable solutions for heavy metal removal due to their strong adsorption abilities and environmentally friendly nature.

Experimental and Theoretical Studies on Reaction Kinetics, Mechanism, and Degradation of Quinoline‐Based Herbicide with Hydroxyl Radical, Sulphate Radical Anion, and Hydrated Electron

ChemPhysChem, EarlyView.
Advanced oxidative process is commonly used for the degradation/removal of herbicides from soil/water bodies. It mostly involves oxidizing •OH and SO4•−$\text{SO}_{4}^{\cdot -}$ species. The present study involves an experimental and theoretical approach to explore kinetics, mechanism, and degradation pathways for 8–quinoline carboxylic acid (8QCA ...

Are the results of the groundwater model robust? [PDF]

arXiv, 2019
De Graaf et al. (2019) suggest that groundwater pumping will bring 42--79\% of worldwide watersheds close to environmental exhaustion by 2050. We are skeptical of these figures due to several non-unique assumptions behind the calculation of irrigation water demands and the perfunctory exploration of the model's uncertainty space.

Sediment supply control on morphodynamic processes in gravel‐bed river widenings

Earth Surface Processes and Landforms, Volume 47, Issue 15, Page 3415-3434, December 2022., 2022
Mobile‐bed laboratory experiments combined with two‐dimensional hydrodynamic numerical simulations showed that sediment supply is a key driver of morphodynamic activity in reach‐scale dynamic river widenings. Sediment supply roughly balanced with the channel's transport capacity led to active channel widening and continued patchy sediment relocation ...

The Energy Balance of Groundwater Flow [PDF]

, 1996
An energy balance of groundwater flow is introduced. It is based on equating the change of hydraulic energy flux over a horizontal distance to the conversion rate of hydraulic energy into to friction of flow over that distance. The energy flux is calculated on the basis of a multiplication of the hydraulic potential with the flow velocity, and is ...
