A fast threshold segmentation method for froth image base on the pixel distribution characteristic.

open access: yesPLoS ONE, 2019
With the increase of the camera resolution, the number of pixels contained in froth image is increased, which brings many challenges to image segmentation. Froth size and distribution are the important index in froth flotation.

3D Knitted Interfacial Solar Steam Generator for High‐Efficiency and Long‐Term Seawater Desalination

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The hydrophobic bottom provides buoyancy to keep the evaporator floating, and directional vertical spacer yarn supplies sufficient water. The knitted photothermal layer efficiently converts solar energy via multiple light reflections. The Marangoni effect induced by edge yarn accelerates the backflow of salt ions, preventing salt accumulation in the ...

Photothermal–Magnetocaloric Coupled Evaporators for Actively Adjustable Water Evaporation and Oil–Water Purification in Complex Environments

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A photothermal–magnetocaloric coupled aerogel evaporator is developed for actively adjustable water evaporation in complex environments. Magnetocaloric heating provides active energy compensation under low‐light conditions and disrupts interfacial hydrogen‐bond networks to promote evaporation.

Structure‐Driven Thermal Insulation Through Single‐ and Double‐Shell Hollow Silica Nanospheres Via a Single‐Step Sacrificial‐Interlayer Strategy

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A single‐step sacrificial‐interlayer strategy enables precise modulation of inter‐shell spacing in hollow silica nanospheres, allowing direct comparison of thermal insulation characteristics between single‐ and double‐shell architectures. The hierarchical design amplifies phonon scattering and disrupts solid heat pathways, achieving an ultralow thermal
