| 1 | A versatile ligand-assisted cooperative template method to synthesize multi-shelled mesoporous hollow metal hydroxide and oxide nanospheres as catalytic reactors显示文摘Nowadays,multi-shelled mesoporous hollow metal oxide nanospheres have drawn a lot of attention due to their large internal space,nanometer scaled shell thickness,high specific surface area and well-defined mesopores,of which unique nanostructure endows metallic oxides with enhanced properties.In this thesis,we have studied and proposed a versatile ligand-assisted cooperative template method to synthesize multi-shelled mesoporous hollow metal hydroxides and oxides nanospheres,in which silica nanospheres act as sacrificial templates and the coordination interaction between metal ions and surfactant can be cooperatively amplified by using chelating ligand(ascorbic acid)as a co-template.The synthesized metal hydroxides and oxides nanospheres possess stable hollow structure,uniform spherical morphology and tunable diameter from 270 to 690 nm.All the multi-shelled mesoporous hollow metal hydroxide and metal oxide nanospheres exhibit high surface areas(up to 640 m^(2)/g).The obtained Au nanoparticles loaded composited nanospheres exhibit excellent reactivity for solvent-free aerobic oxidation of ethylbenzene with high activity(28.2%)and selectivity(87%). | Jingwei Liu Yali Ma Liangliang Zhang Yuenan Zheng Rui Zhang Ling Zhang Feng Wei Zhen-An Qiao | 2021 | Nano Research2021，14，9： | 2 |
| 2 | Centimeter-Deep NIR-II Fluorescence Imaging with Nontoxic AIE Probes in Nonhuman Primates显示文摘Fluorescence probes with aggregation-induced emission(AIE)characteristics are of great importance in biomedical imaging with superior spatial and temporal resolution.However,the lack of toxicity studies and deep tissue imaging in nonhuman primates hinders their clinical translation.Here,we report the blood chemistry and histological analysis in nonhuman primates treated with AIE probes over tenfold of an intravenous dose of clinically used indocyanine green(ICG)during a study period of 36 days to demonstrate AIE probes are nontoxic.Furthermore,through bright and nontoxic AIE probes and fluorescence imaging in the second window(NIR-II,1,000-1,700 nm),we achieve an unprecedented 1.5-centimeter-deep vascular imaging in nonhuman primates,breaking the current limitation of millimeter-deep NIR-II fluorescence imaging.Our important findings,i.e.,nontoxic features of AIE probes and centimeter-deep NIR-II vascular imaging in nonhuman primates,may facilitate successful translation of AIE probes in clinical trials. | Zonghai Sheng Yaxi Li Dehong Hu Tianliang Min Duyang Gao Jen-Shyang Ni Pengfei Zhang Yuenan Wang Xin Liu Kai Li Hairong Zheng Ben Zhong Tang | 2020 | Research2020，，1： | 1 |
