Membrane-forming conditions including solution concentration, pre-evaporation time, evaporation temperature and bath temperature have different influences on the properties of cellulose membrane, e.g. the water flux and the ability to retain glucosan T40. Cellulose membrane has a high ability to rem

In the present study the electrical conductivity ( u ) of ball-milled and NaOH-treated cotton fibers were measured in vacuum. The induced electrical conductivity and the activation energy A E of y-irradiated samples were measured as a function of radiation doses and at various temperatures. I t was
Nonvolatile products have been identified that arise through y-irradiation in isotactic polypropylene by Fourier transform infrared (FTIR) analysis. The y-irradiation was performed in the air with doses varying between 20 and 1200 kGy, for a dose rate of 800 Gy/h. The contour lines of FTIR absorptio
