Enhanced Electrochemical Performance of Aprotic Li-CO Batteries with a Ruthenium-Complex-Based Mobile Catalyst.

Li-CO batteries are regarded as next-generation high-energy-density electrochemical devices. However, the greatest challenge arises from the formation of the discharge product, Li CO , which would accumulate and deactivate heterogenous catalysts to cause huge polarization. Herein, Ru(bpy) Cl was employed as a solution-phase catalyst for Li-CO batteries and proved to be the most effective one screened so far.

[Effects of deficit irrigation on water-radiation use and yield of Coffea arabica under different shade cultivation modes in dry-hot region].

The yield and quality of Coffea arabica cannot be guaranteed due to irrational irrigation and light management in dry-hot region. To investigate the best coupling mode of irrigation and shade cultivation of C. arabica in dry-hot region, a field experiment was carried out with different irrigation levels and shade cultivation modes.

[Coupling mode of irrigation and shading for good quality and proper yield of Coffea arabica in dry-hot region].

In a field experiment with three levels of irrigation, i.e., CI, DI and DI(100%, 75% and 50% full irrigation) and four levels of shade, i.
