Rare-earth doped β-NaYbF4 upconversion phosphors were synthesized using a simple hydrothermal procedure.It is found that under 980 nm excitation β-NaYbF4:0.1%Tm are more efficient than β-NaYF4:20%Yb,0
The 2μm thick DLC film was deposited by unbalanced magnetron sputtering technique on quenched W9 high-speed steel substrate,and the membrane-based system was treated with cryogenic treatment at-196℃ f
A new Diels-Alder Adduct of C60 with 1,1-biindene (CB) has been synthesized.The Langmuir trough study of this new fullerene derivative indicates that floating film could form monomolecular thick film
The capacity for removing particles of different cleaning agent was characterized by the fractal dimension of different wafer surface.At the same time the linear equations of fractal dimension and the
Li3V2 (PO4)3/C is prepared by sol-gel combined with ball milling method (SG-BM).The composites were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron
Based on the industrial production of nonoriented silicon steel, calcium treatment by calcium alloy adding during the RH refining process was studied.The changes of inclusion, crystal texture and micr
Superhydrophobicity is a common characteristic of many plant leaf surfaces.In the present study,a superhydrophobic biomorphic carbon surface was fabricated by sintering the rice and indicalamus leaves
Many plant leaves found in nature are known to exhibit a characteristic of superhydrophobicity (lotus leaf effect).The present study proposes a solution-immersion and sintering method to fabricate a h
