Tuning FeO for sustainable cathodic heterogeneous electro-Fenton catalysis by acetylated chitosan.

Peroxidase-like catalysts are safe and low-cost candidates to tackle the dilemma in constructing sustainable cathodic heterogeneous electro-Fenton (CHEF) catalysts for water purification, but the elusive structure-property relationship of enzyme-like catalysts constitutes a pressing challenge for the advancement of CHEF processes in practically relevant water and wastewater treatment. Herein, we probe the origins of catalytic efficiency in the CHEF process by artificially tailoring the peroxidase-like activity of FeO through a series of acetylated chitosan-based hydrogels, which serve as ecofriendly alternatives to traditional carbon shells. The optimized acetylated chitosan wrapping FeO hydrogel on the cathode shows an impressive activity and stability in CHEF process, overcoming the complicated and environmentally unfavored procedures in the electro-Fenton-related processes.

[Preoperative traction of calcaneus in the treatment of Rüedi-Allgöwer II and III pilon fracture].

Objective: To explore the role of preoperative calcaneal traction in the treatment of Rüedi-Allgöwer II and III Pilon fracture.

Methods: From March 2005 to March 2010, 56 patients with Rüedi-Allgöwer II and III Pilon fracture were treated by calcaneal traction internal fixation on the second phase. There were 42 males and 14 females with an average age of 34.
