Starch/polyvinyl alcohol blended materials used as solid carbon source for tertiary denitrification of secondary effluent.

J. Environ. Sci. (China) 25(10) , 1972-9, (2013)

Starch/polyvinyl alcohol (PVA) blended materials for using as a solid carbon source (SCS) were prepared by blending PVA and gelatinized starch in an aqueous solution system, in which PVA served as framework material and starch as carbon source. The optimizati...

Alkali recovery using PVA/SiO2 cation exchange membranes with different -COOH contents.

J. Hazard. Mater. 244-245 , 348-56, (2013)

By changing -COOH content in poly(acrylic acid-co-methacryloxypropyl trimethoxy silane (poly(AA-co-γ-MPS)), a series of PVA/SiO(2) cation exchange membranes are prepared from sol-gel process of poly(AA-co-γ-MPS) in presence of poly(vinyl alcohol) (PVA). The m...

High-resolution direct 3D printed PLGA scaffolds: print and shrink.

Biofabrication 7(1) , 015002, (2014)

Direct three-dimensional printing (3DP) produces the final part composed of the powder and binder used in fabrication. An advantage of direct 3DP is control over both the microarchitecture and macroarchitecture. Prints which use porogen incorporated in the po...
