Relationship of Dye Adsorption Onto Biomass Activated Carbon Mixed Matrix Ultrafiltration: A Mass Transfer Model Study

Advanced Materials Interfaces, EarlyView.
This study explored dye molecule adsorption from water, focusing on activated carbon in polymer membranes for purifying low‐quality water. Polyvinylidene fluoride (PVDF) membranes showed enhanced removal efficiency of methylene blue (MB) from 89.29% to 98.33% with biomass‐activated carbon (BAC).

Experimental Study on the Effect of the Rack Structure on the Hydrodynamic Characteristics of Truss-type Leg

Shiyou jixie, 2019
The rack and pinion system is the most commonly used lifting system for jack-up offshore platforms. There are relatively few studies on the influence of rack structure on the hydrodynamic characteristics of truss-type legs.
