| 1 | Topotactically constructed nickel-iron(oxy)hydroxide with abundant in-situ produced high-valent iron species for efficient water oxidation显示文摘The low efficiency of oxygen evolution reaction(OER) is regarded as one of the major roadblocks for metal-air batteries and water electrolysis.Herein,a high-performance OER catalyst of NiFe_(0.2)(oxy)hydroxide(NiFe_(0.2)-O_(x)H_(y)) was developed through topotactic transformation of a Prussian blue analogue in an alkaline solution,which exhibits a low overpotential of only 263 mV to reach a current density of 10 mA cm^(-2) and a small Tafel slope of 35 mV dec-1.Ex-situ/operando Raman spectroscopy results indicated that the phase structure of NiFe_(0.2)-O_(x)H_(y) was irreversibly transformed from the type of α-Ni(OH)_(2) to γ-NiOOH with applying an anodic potential,while ex-situ/operando 57Fe Mossbauer spectroscopic studies evidenced the in-situ production of abundant high-valent iron species under OER conditions,which effectively promoted the OER catalysis.Our work elucidates that the amount of high-valent iron species in-situ produced in the NiFe(oxy)hydroxide has a positive correlation with its water oxidation reaction performance,which further deepens the understanding of the mechanism of NiFe-based electrocatalysts. | Zhichong Kuang Song Liu Xuning Li Meng Wang Xinyi Ren Jie Ding Rile Ge Wenhui Zhou Alexandre IRykov Moulay TSougrati Pierre-Emmanuel Lippens Yanqiang Huang Junhu Wang | 2021 | Journal of Energy Chemistry2021，30，6： | 2 |

| 14 | Systemic delivery of microRNA for treatment of brain ischemia显示文摘Brain ischemia is the second leading cause of death and the third leading cause of disability in the world.Systemic delivery of microRNA,a class of molecules that regulate the expression of cellular proteins associated with angiogenesis,cell growth,proliferation and differentiation,holds great promise for the treatment of brain ischemia.However,their therapeutic efficacy has been hampered by poor delivery efficiency of microRNA.We report herein a platform technology based on microRNA nanocapsules,which enables their effective delivery to the disease sites in the brain.Exemplified by microRNA-21,intravenous injection of the nanocapsules into a rat model of cerebral ischemia could effectively ameliorate the infarct volume,neurological deficit and histopathological severity. | Chaoyong Liu Jing Wen Dai Li Hongzhao Qi Lina Nih Jialin Zhu Duo Xu Yu Ren Shanshan Zhang Donglin Han Huanhuan Jia Junhu Zhou Meng Qin Jialing Wu Xubo Yuan Ji Liu Jin Zhao Chunsheng Kang Yunfeng Lu | 2021 | Nano Research2021，14，9： | 0 |
