The full utilization of renewable raw materials is necessary for a sustainable economy. Lignin an abundant biopolymer, but currently mainly used energy production. Ethanol organosolv pre-treatment produces high-quality lignin, still faces substantial economic challenges. solubility increases with temperature, and previous studies have shown that it reprecipitates during cooling after the pre-tr...

To achieve the utilization of fine ilmenite (especially ?0.075 mm) produced in titanium-magnetite processing plant Panzhihua, a radial turbulent outer-cylinder magnetic separator (RTOCMS), was developed this study. After optimizing conditions rotation speed and water flow, an RTOCMS concentrate with TiO2 grade 22.84% recovery 66.93% obtained through one-stage roughing pre-concentration flowshee...

This study examined physiological effects of separation and reunion in a sample 3- to 6-year-old children. Using continuous ambulatory recording, changes in heart rate (HR), respiratory sinus arrhythmia (RSA), and pre-ejection period (PEP) were compared across the episodes of a separation-reunion procedure based on the strange situation. RSA decreased significantly over the course of the proced...
