Design method for bionic topology optimization of high-specific-stiffness mirrors based on additive manufacturing.

Aiming at the demand for high-specific stiffness of space optical mirrors, this study proposes a bionic topology optimization design method for mirrors based on additive manufacturing. First, the principle and process of the Voronoi structure bionic topology optimization method are presented. The optimal design and analysis of the mirrors were then conducted using this method.

Remarkable phosphate recovery from wastewater by a novel Ca/Fe composite: Synergistic effects of crystal structure and abundant oxygen-vacancies.

Calcium-based materials are considered to be promising adsorbents for phosphate removal in the water environment due to their environmental friendliness and low price. However, improving the efficiency and rate of P adsorption of calcium-based materials still needs further exploration. In this study, a high-efficiency and eco-friendly Ca/Fe composite was rationally designed and fabricated by a co-precipitated method.

Activation of dissolved molecular oxygen by Cu(0) for bisphenol a degradation: Role of Cu(0) and formation of reactive oxygen species.

In this study, Cu(0) was synthesized with NaBH as a reducing agent for Cu(II) and used to activate dissolved molecular oxygen (O) under acidic conditions. The Cu(0) synthesized had much higher activity than the purchased. The roles of Cu was clarified and the formation of reactive oxygen species was discussed through direct detection for the first time.
