An improved deep learning network for image detection and its application in Dendrobii caulis decoction piece.

In recent years, with the increasing demand for high-quality Dendrobii caulis decoction piece, the identification of D. caulis decoction piece species has become an urgent issue. However, the current methods are primarily designed for professional quality control and supervision.

Ag-decorated GaN for high-efficiency photoreduction of carbon dioxide into tunable syngas under visible light.

Visible light-driven photoreduction of COand HO to tunable syngas is an appealing strategy for both artificial carbon neutral and Fischer-Tropsch processes. However, the development of photocatalysts with high activity and selectivity remains challenging. For this case, we here design a hybrid catalyst, synthesized bydeposition of Ag crystals on GaN nanobelts, that delivers a tunable H/CO ratio between 0.

Fe-doped MoSnanosheets array for high-current-density seawater electrolysis.

Designing highly active and cost-effective electrocatalysts for seawater-splitting with large current densities is compelling for developing hydrogen energy. Great advancements in hydrogen evolution reaction (HER) have been achieved, but the progress on driving HER in seawater is still limited. Herein, Fe-doped MoSnanoshseets array supported by 3D carbon fibers was explored to be an efficient HER electrocatalyst operating in seawater.
