Synergistic effects of oxygen vacancies and mesoporous structures in amorphous C@TiO for photocatalytic CO reduction.

In this study, the theoretical calculations proves that the combination of oxygen vacancy and amorphous carbon films in TiO (V-CT) can effectively reduce the energy bandgap and work function. The minimum Gibbs free energies required for the CORR reaction of V-CT are 0.20 eV, which is lower than pure TiO.

Oxygen vacancy enhanced photocatalytic activity of CuO/TiO heterojunction.

In this study, a method was developed to create oxygen vacancies in CuO/TiO heterojunctions. By varying the amounts of ethylenediaminetetraacetic acid (EDTA), sodium citrate, and copper acetate, CuO/TiO with different Cu ratios were synthesized. Tests on CO photocatalytic reduction revealed that CuO/TiO's performance is influenced by Cu content.

Design and characteristic research of smart rod based on optical fiber grating for strain monitoring of power transmission tower.

The safety of the power transmission towers is the basis for the reliable operation of the power grid. Real-time monitoring of the strain of the key rods of the power transmission tower can reflect the safety status of the power transmission tower. In this paper, a smart rod equipped with fiber Bragg grating with strain sensitivity enhanced structure is proposed to detect the strain of key rods of large-span power transmission towers on the southeast coast of the Yangtze River.

One-step synthesis of cubic FeS2 and flower-like FeSe2 particles by a solvothermal reduction process.

In this paper, for the first time a simple batch process was utilized for the facile synthesis of cubic FeS(2) and flower-like FeSe(2). By adjusting the amount of solvents and surfactants added, pure pyrite FeS(2) with a defined crystalline structure was obtained. It was found that the reaction temperatures and iron sources had significant influence on the purities and morphologies of FeS(2) and FeSe(2) particles.
