Ultrafast particle and cell concentration is essential to the success of subsequent analytical procedures and the development of miniaturized biological and chemical sensors. Here, surface acoustic wave (SAW) devices were used to excite a MHz-order acoustic wave that propagates into a microlitre droplet to drive spatial concentration and separation of two different sized suspended microparticle...

This study shows that revising the reaction rate of NO2+HO q →HNO3 improves simulated nitrogen partitioning and changes the simulated radiative effects of several short-lived climate forcers (SLCF). Both laboratory and field study analyses have found that the reaction rate should be reduced by 13–30 % from current recommendations. We evaluate the GEOS-Chem model over North America with and with...

The corrosion resistance of solution annealing heat-treated type 2205 duplex stainless steel microstructures was assessed with a bipolar electrochemistry technique. Chemical element partitioning in both crystallographic phases correlated to simulations critical pitting temperatures. as-received microstructure had the highest pit nucleation resistance, high-temperature treatment revealing reduce...

The partitioning of organic soil pollutants into soil organisms is driven by their chemical activity, which normally does not exceed that of the pure pollutant. Passive dosing with the silicone poly(dimethylsiloxane) (PDMS) was used to initiate and maintain the maximum chemical activity of 10 polycyclic aromatic hydrocarbons (PAHs) in toxicity tests with the springtail Folsomia candida. The tes...

The partitioning of semivolatile organic compounds between the gas phase and aerosol particles is an important source of secondary organic aerosol (SOA). Gasparticle partitioning of organic and inorganic species is influenced by the physical state and water content of aerosols, and therefore ambient relative humidity (RH), as well as temperature and organic loading levels. We introduce a novel ...

Despite a multitude of small catchment studies, we lack deep understanding how variations in critical zone architecture lead to hydrologic states and fluxes. This study characterizes dynamics 15 catchments the U.S. Critical Zone Observatory (CZO) network where hypothesized that our subsurface structure would illuminate patterns partitioning. The CZOs collect data sets characterize physical, che...

Atmospheric rainfall is one of the major sources water and nutrient inputs in forest stands. Understanding atmospheric partitioning hydrochemical fluxes stands critical for management monitoring regional pollution, especially high N deposition regions. In this study, annual collections were implemented to investigate partitioning, element concentrations, an evergreen coniferous (ECF) stand, a d...

Abstract Poly-parameter Linear Free Energy Relationships (PPLFERs) based on the Abraham solvation model are a useful tool for predicting and interpreting equilibrium partitioning of solutes in solvent systems. The focus this work is neutral organic liquid solvent-air This follow-up to previous (Brown, 2021) which developed predictive empirical correlations between solute descriptors system para...
