Yttrium chloride can be used to prepare composite coatings on resin surfaces. A method for recovering rare earth element yttrium from waste fluorescent powder and preparing resin surface composite coating.
2. Effect on human epidermal cells: Yttrium is a rare element and has no effect on the in vitro proliferation of epidermal cells at low concentrations. Yttrium chloride has a certain effect on UV induced apoptosis of epidermal cells. Research results show that adding low concentration yttrium chloride 0.1mmol/L to cultured human epidermal cells has a certain protective effect on UV induced apoptosis; Compared with the control group, the high concentrations of 2.0 and 3.0 mmol/L yttrium chloride showed no significant difference statistically, but the apoptosis rate of epidermal cells was higher. This indicates that yttrium chloride may have a bidirectional effect on epidermal cell apoptosis. Low concentrations may protect against UV induced epidermal cell apoptosis, while high concentrations may promote epidermal cell apoptosis. The mechanism of action needs further research.
【Introduction】
1. Preparation of Yttrium Chloride for Composite Coating on Resin Surface and Method for Recovering Rare Earth Element Yttrium from Waste Fluorescent Powder
-Preparation of Composite Coatings: Yttrium chloride can be used to prepare composite coatings on resin surfaces. This coating can improve the performance of the resin, such as enhancing its corrosion resistance, wear resistance, and optical properties.
-* * Recycling Yttrium from Waste Fluorescent Powder * *: Waste fluorescent powder contains rare earth element yttrium, which can be recovered through chemical methods. The usual steps include dissolving, separating, and purifying the waste fluorescent powder to obtain high-purity yttrium chloride.
2. The effect of Yttrium Chloride on human epidermal cells
-* * Protective effect at low concentrations * *: In vitro experiments, low concentrations of yttrium chloride (such as 0.1 mmol/L) have no significant effect on the proliferation of human epidermal cells, but have a certain protective effect on UV induced apoptosis of epidermal cells.
-The pro apoptotic effect at high concentrations: High concentrations of yttrium chloride (such as 2.0 mmol/L and 3.0 mmol/L) significantly increase the apoptosis rate of epidermal cells, with no statistical difference compared to the control group, but the apoptosis rate is higher.
-* * Dual effect mechanism * *: Yttrium chloride may have a dual effect on epidermal cell apoptosis, protecting cells from UV induced apoptosis at low concentrations and promoting apoptosis at high concentrations.
-* * Mechanism of action * *: Yttrium chloride may affect cell apoptosis by inducing excessive production of reactive oxygen species (ROS), disrupting mitochondrial membrane potential (Δ PSI m), and causing DNA damage. However, its specific mechanism still needs further research.
In summary, yttrium chloride has potential application value in the preparation of composite coatings and the recovery of rare earth elements from waste fluorescent powders. At the same time, its effect on human epidermal cells is concentration dependent, with protective effects at low concentrations and potential promotion of cell apoptosis at high concentrations.
