Water reorientation dynamics in colloidal water–oil emulsions
Physical Chemistry Chemical Physics, 2021Polarization resolved pump–probe infrared spectroscopy of colloidal oil-in-water emulsions demonstrates that the total surface area of oil droplets is independent of the average droplet size, indicating that the oil droplets are strongly corrugated.

Placenta, 2007
Water arrives in the mammalian gestation from the maternal circulation across the placenta. It then circulates between the fetal water compartments, including the fetal body compartments, the placenta and the amniotic fluid. Amniotic fluid is created by the flow of fluid from the fetal lung and bladder.

Physical Review E, 1999
Water beneath a layer of oil in a producing reservoir may rise and form a bell-shaped cone in the vicinity of the well. We discuss how the dynamics of cone formation in two dimensions depends on the gravitational contrast, the interfacial tension, and the flow rate of oil. For a constant flow rate below a critical rate Q(c), stable cones are formed. At

Water Dynamics in Water/DMSO Binary Mixtures
The Journal of Physical Chemistry B, 2012The dynamics of dimethyl sulfoxide (DMSO)/water solutions with a wide range of water concentrations are studied using polarization selective infrared pump-probe experiments, two-dimensional infrared (2D IR) vibrational echo spectroscopy, optical heterodyne detected optical Kerr effect (OHD-OKE) experiments, and IR absorption spectroscopy.

Water insecurity poses threats to both human welfare and ecological systems. Global water abstractions (extractions) have increased threefold over the period 1960–2010, and an increasing trend in abstractions is expected to continue. Rising water use is placing significant pressure on water resources, leading to depletion of surface and underground ...

Quantum Dynamics in Water Clusters
2021The ring-polymer instanton method is used to calculate tunneling pathways and hence tunneling splitting patterns of the water dimer, trimer, pentamer, and hexamer prism. We discuss recent developments to improve the efficiency of thismethod and present results utilizing the MB-pol potential-energy surface.

Nucleation Dynamics of Water Nanodroplets
Microscopy and Microanalysis, 2014AbstractThe origin of the condensation of water begins at the nanoscale, a length-scale that is challenging to probe for liquids. In this work we directly image heterogeneous nucleation of water nanodroplets by in situ transmission electron microscopy.

Probing water dynamics with OH−
Chemical Physics, 2007Abstract Isotropic Raman spectra of aqueous solutions of LiOH, NaOH and KOH at concentrations ranging from high dilution to saturation have been measured and the frequency and width of the OH − stretching band have been analyzed. The dependence of the bandwidth on solute concentration suggests that the OH − vibration undergoes a transition from ...

Dynamic Heterogeneities in Supercooled Water
The Journal of Physical Chemistry B, 2004We investigate dynamic heterogeneities in liquid water by performing molecular dynamics simulations of the SPC/E model. We find clusters of mobile molecules. We study the temperature and time dependence of the cluster size and find that clusters grow as temperature decreases and have a maximum size at the time scale corresponding to the escape of the ...

An analysis of the results of hydrographic surveys and satellite measurements performed during in roughly the last two decades is presented in order to demonstrate the diversity of manifestations of the mesoscale water dynamics in the coastal zone and in the deep-water part of the Black Sea and the role of mesoscale structures (eddies and jets) in the ...
