材料科学技术（英文）

ZnS nano-particles with average sizes of 10 nm and 5 nm were fabricated by sol-gel method, and their pressure-induced phase transformations were in-situ examined in a diamond anvil cell by energy dispersive X-ray diffraction (EDXD) from ambient pressure to 35.0 GPa. From the obtained interplanar spa...
