Sulfated chitosan (SCS)/polysulfone (PS) composite nanofiltration membrane surface cross-linked by Epichlorohydrin

Miao J., Xie Z.H., Chen G.H., Edith Cowan University, AU

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 [...]

Structural and Thermo-Mechanical Characterization of Calcium and Barium Alginate Films

Vidal-Urquiza T.K., University of Puerto Rico, PR

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 [...]

Sodium Clusters for a Superior Light Source

Gokturk H., Ecoken, US

Sodium lamp is one of the most efficient light sources providing an output of 150-200 lumens/watt; for comparison, light output of a fluorescent lamp is about 60-100 lumens/watt. Despite its efficient operation, sodium lamp is [...]
