膨胀石墨对非离子表面活性剂的吸附研究

以膨胀石墨为吸附剂,研究它对非离子表面活性剂的吸附情况。主要探讨了非离子表面活性剂的浓度、吸附时间、吸附温度、膨胀石墨粒度及不同浓度的NaCl溶液对吸附行为的影响,结果表明,在适宜条件下,膨胀石墨对壬基酚聚氧乙烯醚非离子表面活性剂的吸附速率较快;最大吸附量约为259．50μg／g,在非离子表面活性剂处理方面显示出良好的吸附性能。     

Visualizing interface states in In2Se3–WSe2 monolayer lateral heterostructures

Recent findings of two-dimensional(2D) ferroelectric(FE) materials provide more possibilities for the development of 2D FE heterostructure electronic devices based on van der Waals materials and the application of FE devices under the limit of atomic layer thickness. In this paper, we report the in-situ fabrication and probing of electronic structures of In₂Se₃–WSe₂ lateral heterostructures, compared with most vertical FE heterostructures at present. Through mole...
