Silica Surface Charge Enhancement at Elevated Temperatures Revealed by Interfacial Water Signals

Journal of the American Chemical Society, 2020
The structure of water adjacent to silica is sensitive to the degree of deprotonation of surface silanol groups. As a result, close inspection of signals originating from these water molecules can be used to reveal the surface charge density. We have used nonlinear vibrational spectroscopy of the water O-H stretching band over a temperature range of 10-

Elevated Water Oxidation by Cation Leaching Enabled Tunable Surface Reconstruction

Angewandte Chemie
AbstractWater electrolysis is one promising and eco‐friendly technique for energy storage, yet its overall efficiency is hindered by the sluggish kinetics of oxygen evolution reaction (OER). Therefore, developing strategies to boost OER catalyst performance is crucial. With the advances in characterization techniques, an extensive phenomenon of surface

An algorithm for calculating water surface elevations from surface gradient image data

Experiments in Fluids, 1996
2-D water surface gradient data can be measured by a 2-D gradient detector (Zhang and Cox 1991; Zhang et al. 1993). An algorithm for the reconstruction of water surface elevation from measured surface gradient data is described in some detail. The boundary and noise effects are explored.

Use of upscaled elevation and surface roughness data in two-dimensional surface water models

Advances in Water Resources, 2011
In this paper, we present an approach that uses a combination of cell-block- and cell-face-averaging of high-resolution cell elevation and roughness data to upscale hydraulic parameters and accurately simulate surface water flow in relatively low-resolution numerical models.

Assimilation of SWOT water surface elevation data for enhanced modeling of surface water dynamics

This study advances the data assimilation (DA) capabilities of NASA’s Land Information System (LIS) by integrating flood models and hydrological DA using observations from the Surface Water and Ocean Topography (SWOT) mission. Traditionally limited to land surface models, LIS now incorporates SWOT’s high-resolution, wide-swath altimetry to produce ...

Validation of swot water surface elevations in estuaries and deltas

The Surface Water and Ocean Topography (SWOT) mission launched in December 2022 and collected data every 1-day during the calibration/validation orbit from May-July of 2023 before switching to the science orbit for global data collection. While SWOT is designed to capture ocean and inland water processes, data application and processing in the coastal ...

Elevated Levels of Tritium in Surface Water Collected in the Immediate Aftermath of the Fukushima Accident

Environmental Pollution
The Fukushima Daiichi Nuclear Power Plant (FDNPP) accident in 2011, triggered by the Tohoku earthquake and tsunami, released a substantial amount of radionuclides into the environment, including approximately 2.7 PBq of 137Cs and 200-210 TBq of tritium (3H).

Biological Effects of Elevated Major Ions in Surface Water Contaminated by a Produced Water from Oil Production

Archives of Environmental Contamination and Toxicology, 2019
Produced water (PW) from oil and gas extraction processes has been shown to contain elevated concentrations of major ions. The objective of this study was to determine the potential effects of elevated major ions in PW-contaminated surface water on a fish (fathead minnow, Pimephales promelas) and a unionid mussel (fatmucket, Lampsilis siliquoidea) in ...

Pulsed laser-induced water surface elevation and its relationship to the Abraham momentum

Optics Letters
We present a theoretical framework to address the challenge of modelling the liquid surface deformation under pulsed laser illumination for normal and oblique incidence, a key bottleneck in linking optical forces with fluid dynamics.

Investigation of the Cause of the Spontaneous Elevation of Small Particles of Water in the Air Above the Surface of the Water

2014
We elegantly confirmed above (by altering and deforming a spherical shape) the truth of the theory of Archimedes according to whom all elementary bodies either fluid or consistent have gravity and exert this gravity even in their proper places. From this it is deduced that water for instance cannot transgress the laws of equilibrium nor disturb the ...
