The “Software Package for Aerosol Size Distribution” is a novel graphical user interface application software used for the study of atmospheric aerosol size distribution from various aerosol models (Continental clean, Continental average, Continental polluted, Urban, Desert, Maritime clean, Maritime polluted, Maritime tropical, Arctic, Antarctic) and/or with different aerosol components (insolu...

Tropical plant species exhibit a high degree of variability in salt tolerance, probably as a result of evolution in diverse ecosystems, intensive year-round selection pressures, and high temperatures. Salinity may cause major problems for agricultural production in semiarid tropics and areas subjected to seawater intrusion, and is also a concern in any irrigated region subjected to high tempera...

We hypothesized that custom-designed microemulsions would effectively scavenge compounds from bulk media. Pluronic-based oil-in-water microemulsions were synthesized that efficiently reduced the free concentration of the local anesthetic bupivacaine in 0.9% NaCl. Both the molecular nature and concentration of the constituents in the microemulsions significantly affected extraction efficiencies....

The Algal-Bacterial Selenium Removal (ABSR) system has demonstrated an ability to efficiently remove nitrogen from agricultural drainage water in the San Joaquin Valley. However, it is not known whether the ABSR system can effectively reduce nitrate and nitrite concentrations in drainage water with high levels of salinity. In order to determine whether the ABSR system can be used to treat salty...

Studying the earliest stages of precipitation at the nanoscale is technically challenging but quite valuable as such phenomena reflect important processes such as crystallization and biomineralization. Using a quartz nanopipette as a nanoreactor, we induced precipitation of an insoluble salt to generate oscillating current blockades. The reversible process can be used to measure both kinetics o...

Capacitive Deionization [2] (CDI [3]) is a water [4] purification process that offers promise in the deionization of salt and brackish water [4]. The process can create potable water [4] out of salt laden water [4] by using electric currents to separate the ions in the solution and attract them to cathode and anode plates. These plates act as filters, drawing salt and other ionized metals out o...

To investigate the effect of calcium salts on the thermodynamic and transport properties of aqueous solutions of proteins, we report ternary diffusion coefficients for the lysozyme-CaCl2-water ternary system at 25 degrees C and pH 4.5. We have used our ternary diffusion coefficients to calculate preferential-interaction coefficients as a function of salt concentration. This has allowed us to ch...

We report in situ spectroscopic measurements monitoring the adsorption of a series of carboxylate surfactants onto the surface of the semisoluble, ionic solid fluorite (CaF2). We employ the surface-specific technique, vibrational sum-frequency spectroscopy (VSFS), to examine the effect that surfactant adsorption has on the bonding interactions and orientation of interfacial water molecules thro...
