Small-angle X-ray scattering (SAXS) data of crosslinked polyelectrolyte membrane films formed under different equilibrium humidity conditions

LLNL researchers have developed a method to enhance the performance of polyelectrolyte membranes by using a humidity-controlled crosslinking process which can be applied to precisely adjust the water channels of the membrane.

Water being decontaminated via photocatalysis

LLNL researchers have developed a method for enhancing the photocatalytic degradation of organic contaminants in water through the incorporation of patterned plasmonic metal nanostructures with TiO2 photocatalysts. The multi-step process to incorporate UV plasmonic metal nanostructures with the photocatalyst can be briefly summarized below:
•    Nanosphere lithography step on…

Simulation of ion selectivity related to pore size in flow through electrode.

LLNL researchers have developed a novel technique of flow-through electrode capacitive deioinization (FTE-CDI) which can be tailored for selective ion removal from water. It uses porous carbon aerogel materials as capacitive deionization (CDI) electrodes to selectively remove scale forming divalent ions (e.g., magnesium, calcium) from "hard" waters.

geothermal steam exhaust

LLNL has a patented process to produce colloidal silica directly from geothermal fluids. Livermore’s process uses membranes to produce a mono-dispense slurry of colloidal silica particles for which there are several applications. LLNL has demonstrated that colloidal silica solutions that result from extraction of silica from geothermal fluids undergo a transition to a solid gel over a range of…

 San Joaquin River headwaters

LLNL has developed a noble gas mass spectrometry facility that houses a state-of-the-art water-gas separation manifold and mass spectrometry system designed specifically for high throughput of groundwater samples. The fully automated, computer-controlled manifold system allows analysis of the full suite of noble gases (3He/4He, He, Ne, Ar, Kr, and Xe concentrations), along with low level…

LLNL has developed an innovative technology known as flow-through electrode capacitive desalination (FTE-CD) that promises to unlock an almost inexhaustible water source for U.S. and global population markets. FTE-CDI represents a robust and low-maintenance path for efficiently and cost-effectively producing clean drinking water from seawater and brackish water.
