Alignate films require its precise characterization of mechanical and thermo-mechanial properties, which are useful for several potential applications in environmental protection, biotechnology, and others areas. Therefore, this work study the aforementioned film properties of sodium [...]
A series of composite nanofiltration membranes were prepared via a method of coating and cross-linking from sulfated chitosan (SCS) as the material of the active layer, Polysulfone (PS) UF membrane as the base membrane, and [...]
RO membrane technologies have made great progress in last 50 years. In seawater and brackish water desalination field, both energy saving and water quality improvement have been two major subjects. Advanced membranes are still demanded [...]
We have developed asymmetric carbon nanotube/polyamide membranes for desalination applications. The carbon nanotubes are functionalized with zwitterionic groups that control the rejection of anionic species, while permitting the transport of water. Water flux measurements demonstrate [...]

We have developed polyamide bi-layer thin film composite membranes to enhance RO-desalination performance. The polyamide bi-lyer membrane consists of conventional non-substituted aromatic polyamide under-layer and HFA-substituted aromatic polyamide top-layer, which can be esaily prepared by [...]
As part of a combined computational and experimental effort to develop new reverse osmosis desalination membrane materials, we have carried out detailed equilibrium and nonequilibrium molecular dynamics simulations of the aromatic polyamide active layers of [...]
Polyaniline (PAN) nanofibers have received much attention owing to their superior properties compared to the conventional bulk PAN[1-3]. PAN nanofibers show enhanced water processability and improved sensitivity and time response when they are exposed to [...]
Spiralcat of Maryland has two pilot demonstration: A Dairy CAFO located within the Chesapeake Bay Watershed brings together precision agriculture and targeted air quality strategies while conserving water, and removing unwanted salts and excess nutrients [...]
Chemicals that are transported in our water can be used to our advantage. Both natural and anthropogenic chemicals can be targeted to understand the way our water behaves. The use of boron isotope compositions has [...]
