Concentration polarization of ion-exchange membranes in electrodialysis units limits operational current densities to the underlimiting regime, preventing process intensification by simply increasing ...

Free-standing symmetrical porous membranes consisting of uniform cylindrical micelles were prepared from a polystyrene-block-poly(4-vinylpyridine) (PS-b-P4VP) diblock copolymer following a process ...

ABSTRACT Total Ammoniacal Nitrogen - TAN (NH 3 + NH 4+) in wastewaters cause environmental degradation concerns due to their negative impacts on air, soil and water. Several technologies are available ...

This paper introduces a cross-spectral metric for subspace selection and rank reduction in partially adaptive minimum variance array processing. The counter-intuitive result that it is suboptimal to ...

Doko et al. (1994), using semi-permeable membrane, ammonium sulfate extraction, centrifugation and freeze-drying processes achieved low-moisture freeze-dried, and light-colored extracts, free of ...

Iran has reopened parts of its airspace for international overflights after a ceasefire with Israel, easing global flight routes, though restrictions on key airports and regions remain in place.
