Visible light-driven triazine-based S-scheme COF-TpTt@BiOBr heterojunction with oxygen vacancy for enhanced photocatalytic pollutants removal and hydrogen production.

S-scheme heterojunction is an effective tactic to improve photocatalytic property. But few studies on constructing heterojunction with BiOBr and covalent organic frameworks (COFs) are available. Herein, a novel series of COF-TpTt@BiOBr S-scheme heterojunctions with oxygen vacancies (OVs) were constructed via solvothermal method.

[Manipulative reduction and internal fixation by percutaneous locking compression plate for the treatment of mid-distal tibiofibula shaft fractures].

Objective: To investigate the clinical effects of manipulative reduction and percutaneous locking compression plate internal fixation for the treatment of mid-distal tibiofibula shaft fractures.

Methods: From January 2006 to October 2009,46 patients suffering from mid-distal tibiofibula shaft fractures were treated with closed manipulative reduction and LCP, involved 27 males and 19 females with an average age of 39 years old ranging from 17 to 56 years. According to AO classification, there were 12 cases of type A, 24 of type B, 10 of type C.
