| 1 | Defect-density control of platinum-based nanoframes with high-index facets for enhanced electrochemical properties显示文摘Structure-engineered platinum-based nanoframes(NFs)at the atomic level can effectively improve the catalytic performance for fuel cells and other heterogeneous catalytic fields.We report herein,a microwave-assisted wet-chemical method for the preparation of platinum-copper-cobalt NFs with tunable defect density and architecture,which exhibit enhanced activity and durability towards the electro-oxidation reactions of methanol(MOR)and formic acid(FAOR).By altering the reduction/capping agents and thus the nucleation/growth kinetics,trimetallic platinum-copper-cobalt hexapod NFs with different density high-index facets are achieved.Especially,the rough hexapod nanoframes(rh-NFs)exhibit excellent specific activities towards MOR and FAOR,7.25 and 5.20 times higher than those of benchmark Pt/C,respectively,along with prolonged durability.The excellent activities of the rh-NFs are assigned to a synergistic effect,including high density of defects and high-index facets,suitable d-band center,and open-framework structure.This synergistic working mechanism opens up a new way for enhancing their electrocatalytic performances by increasing defect density and high-index facets in open-framework platinum-based NFs. | Shaohan Yang Shuna Li Lianghao Song Yipin Lv Zhongyao Duan Chunsheng Li Raphael Francesco Praeg Daowei Gao Guozhu Chen | 2019 | Nano Research2019，12，11： | 3 |

| 7 | Apoptosis induced by NaYF_4:Eu^(3+) nanoparticles in liver cells via mitochondria damage dependent pathway显示文摘As lanthanide-doped sodium yttrium flouride(NaYF_4)nanoparticles have great potential inbiomedical applications,their biosafety is important and has attracted significant attention.In the present work,three different sized NaYF_4:Eu^(3+)nanoparticles have been prepared.Liver BRL 3 A cell was used as a cell model to evaluate their biological effects.Cell viability and apoptosis assays were used to confirm the cytotoxicity induced by NaYF_4:Eu^(3+)NPs.Apart from the elevated malondialdehyde(MDA),the decrease of superoxide dismutase(SOD),glutathione peroxidase(GSH-PX)and catalase(CAT)activity indicated reactive oxygen species(ROS)generation,which were associated with oxidative damage.The decrease of mitochondrial membrane potential(MMP)value demonstrated the occurrence of mitochondria damage.Then,release of cytochrome c from mitochondria and activation of caspase-3 confirmed that NaYF_4:Eu^(3+)NPs induced apoptosis was mitochondria damage-dependent. | Shaohan Zhang Shizhu Chen Chunyue Gao Yi Jin Guang Jia Zhenhua Li Dandan Liu Xingjie Liang Xinjian Yang Jinchao Zhang | 2017 | Science China Chemistry2017，60，1： | 0 |
