Template Removal and Surface Modification of an SSZ-13 Membrane with Heated Sodium Chloride for CO/CH Gas Separation.

Hydrothermal synthesis with an organic template of ,, trimethyl-1-adamantammonium hydroxide (TMAdaOH) is the most commonly used method to prepare an SSZ-13 zeolite membrane. In this paper, the synthesized membrane was treated in heated sodium chloride to remove TMAdaOH instead of calcination in air. The surface of the membrane was modified by the heated NaCl and resulted in an improved CO/CH gas separation selectivity.

Transcatheter arterial embolization for postoperative arterial complications after pelvic or hip surgery.

Purpose: We aimed to study the technical and clinical outcome of urgent transcatheter arterial embolization (TAE) for postoperative arterial complications after pelvic or hip surgery, and to accumulate additional experience about the role of embolization for these injuries.

Methods: Patients who received TAE procedure for arterial complications after pelvic or hip surgery between September 1st, 2002 and December 1st, 2014 were screened on medical records and included in the analysis. Angiographic findings included active contrast agent extravasation, pseudoaneurysm formation, arteriovenous fistula, and other suspicious signs such as sighting of coarse margin or distortion of vessels.
