A novel Electro-Fenton process characterized by aeration from inside a graphite felt electrode with enhanced electrogeneration of HO and cycle of Fe/Fe.

A novel Electro-Fenton process characterized by aeration from inside a graphite felt electrode with enhanced generation of HO and cycle of Fe/Fe was proposed. The new type of Electro-Fenton process was used to degrade organic pollutants via graphite felt electrode aeration (GF-EA). The HO concentration by GF-EA could reach 152-169 mg/L in a wide pH range (3-10), which was much higher than that achieved by graphite felt using solution aeration (GF-SA, 37-113 mg/L).

The grafts modified by heparinization and catalytic nitric oxide generation used for vascular implantation in rats.

Small-diameter (<6 mm) vascular grafts are increasingly needed in peripheral vascular surgery but have few successes because of acute thrombosis, incomplete endothelialization and intimal hyperplasia after implantation. This study used electrospun poly(ε-caprolactone) as the matrix material. Heparin and selenium-containing catalyst-organoselenium modified polyethyleneimine were introduced through layer-by-layer assembly in order to build a vascular graft with nitric oxide (NO) generation.

Regulation of macrophage polarization and promotion of endothelialization by NO generating and PEG-YIGSR modified vascular graft.

As an effective clinic treatment for cardiovascular disease, vascular transplantation gains much acceptance recently. However, due to the acute thrombosis and intimal hyperplasia, long-term failure of synthetic grafts after implanted in small diameter blood vessel decelerates its commercial use. The continued acute inflammation and delayed endothelialization have been considered as fundamental reasons.
