In this study, structural features of NaMZnPO (M = Cu, Ni and Co; x = 0 and 5 mol %) glass compounds were investigated. X-ray diffraction (XRD) and X-ray Absorption Fine Structure (XAFS) analysis techniques were used to investigate the phase identification and the local atomic environment around Zn element. Non-doped and Cu co-doped compounds show an amorphous glassy character while a tetragonal NaZnPO

Peelable Fe-based alloy film specimen for HRTEM observation Mater. Lett. (IF 3.0) Pub Date : 2024-02-29 Yao Zhai, Xiaozhen Fan, Zheng Fang, Huiqun Ye, Jianqiang Zhang, Yanjun Qin, Jinju Zheng, Yunzhang Fang
High-resolution transmission electron microscopy plays a significant role in modern material characterization techniques, while specimen preparation is the key to achieve high-quality observation. A method for preparing TEM specimen of nanometer-thickness amorphous alloy film by non-destructive stripping is proposed in this work. Using magnetron sputtering method to prepare Fe-based amorphous alloy

Carbon spheres decorated with SnS2 nanosheets as a low-cost counter-electrode material for dye-sensitized solar cell Mater. Lett. (IF 3.0) Pub Date : 2024-02-29 Jing Li, Lingyun Li, Yanan Du, Xu Liu, Ligang Wang
In order to utilize the synergistic effect of SnS and CS and further improve the electrochemical performance of SnS, We prepared monodisperse SnS@CS composite using common reagents and a simple solvothermal method, and studied its electrochemical performance as counter electrode (CE) of dye-sensitized solar cell (DSSC). During the preparation process, glucose was used as the carbon source, thioacetamide
