| 1 | Highly efficient luminescent Ⅰ-Ⅲ-Ⅵ semiconductor nanoprobes based on template-synthesized CuInS2 nanocrystals显示文摘CuInS2 semiconductor nanocrystals (NCs) exhibit large absorption coefficient, size-dependent photoluminescence and low toxicity, making them excellent candidates in a variety of bioapplications. However, precise control of both their composition and morphology to improve the luminescent efficiency remains a great challenge via conventional direct synthesis. Herein, we present a novel low-temperature template synthesis of highly efficient luminescent CuInS2 nanoprobes from In2S3 NCs via a facile cation exchange strategy. The proposed strategy enables synthesis of a series of CuInS2 NCs with broad size tunability from 2.2 to 29.6 nm. Through rationally manipulating the stoichiometry of Cu/In, highly efficient luminescence of CuInS2 with the maximum quantum yield of 28.6% has been achieved, which is about one order of magnitude improvement relative to that of directly synthesized NCs. By virtue of the intense emission of CuInS2 nanoprobes, we exemplify their application in sensitive homogeneous biodetection for an important biomolecule of adenosine triphosphate (ATP) with the limit of detection down to 49.3 nM. Moreover, the CuInS2 nanoprobes are explored for ATP-targeted cancer cell imaging, thus revealing their great potentials in the field of cancer diagnosis and prognosis. | Xian Li Datao Tu Shaohua Yu Xiaorong Song Wei Lian Jiaojiao Wei Xiaoying Shang Renfu Li Xueyuan Chen | 2019 | Nano Research2019，12，8： | 3 |
| 2 | Porosity Effects on Mechanical Properties of 3D Random Fibrous Materials at Elevated Temperatures显示文摘In this study,we prepare the specimens of three-dimensional random fibrous(3D RF)material along its through-the-thickness(TTT)and in-plane(IP)directions.The experimental tests of tensile and compressive properties as well as fracture toughness of 3D RF material are performed at elevated temperatures.Then,the porosity(83%,87%and 89%)and temperature dependence of the tensile and compressive strength,elastic modulus,fracture toughness and fracture surface energy of the 3D RF materials for both the TTT and IP directions are analyzed.From the results of the tensile strength and elastic modulus versus material porosities at various temperatures,we find that tensile strength and elastic modulus for the TTT direction are more sensitive to the porosity,but not for the IP direction.Fracture toughness increases firstly and then decreases at a certain critical temperature.Such critical temperature is found to be the lowest for the porosity of 83%.On the other hand,at below 1073 K,the temperature-dependent fracture surface energies with three porosities for the TTT direction show similar variation trends. | Datao Li Wenshan Yu Wei Xia Qinzhi Fang Shengping Shen | 2020 | Acta Mechanica Solida Sinica2020，33，1： | 2 |

| 9 | Exosomes from antler stem cells alleviate mesenchymal stem cell senescence and osteoarthritis显示文摘Dear Editor,Stem cell therapy holds enormous and revolutionary promise to treat various age-related diseases,such as diabetes,heart failure,and Parkinson’s disease.However,low retention and survival rate of delivered stem cells,partially due to immunological rejection,constitute major hurdles for the clinical implementation of stem cell therapy(Lei et al.,2021a).Since mounting evidence showed that several types of stem cells mainly exert their therapeutic effects through the secretion of paracrine effects,exosomes,which are released by stem cells and execute most paracrine functions,have begun to draw attention in the field(Tran and Damaser,2015).Exosomes are membrane-enclosed vesicles with an average diameter of∼100 nanometers secreted by the cells,containing cytokines. | Jinghui Lei Xiaoyu Jiang Wei Li Jie Ren Datao Wang Zhejun Ji Zeming Wu Fang Cheng Yusheng Cai Zheng-Rong Yu Juan Carlos Izpisua Belmonte Chunyi Li Guang-Hui Liu Weiqi Zhang Jing Qu Si Wang | 2022 | Protein & Cell2022，13，3： | 1 |

| 16 | Boosting the Energy Migration Upconversion through Inter-Shell Energy Transfer in Tb^(3+)-Doped Sandwich Structured Nanocrystals显示文摘It remained challenging to fabricate Tb^(3+)-doped lanthanide nanocrystals(NCs)to simultaneously acquire strong energy migration upconversion(EMU)emissions of Tb^(3+)while suppressing the Tm3+UV upconversion emissions that cause background biofluorescence issues in bioapplications based on Tb^(3+)-doped EMU NCs.Herein,we report a novel sandwich structured core@shell@shell scheme for the design of EMU NCs,for example,NaLuF4∶Yb/Gd@NaGdF4∶Tm@NaLuF4∶Tb NCs,wherein Yb^(3+),Tm^(3+),and Tb^(3+)are incorporated separately into the inner core,middle shell,and outer shell,respectively.We found that in the sandwich structured NCs,the effective inter-shell energy transfer from Gd^(3+)in the middle shell to Tb^(3+)in the outer shell accelerated the Yb^(3+)-Tm^(3+)five-photon upconversion and the subsequent Tm^(3+)to Gd^(3+)energy transfer processes,which could eventually lead to almost complete inhibition of Tm^(3+)UV upconversion emissions,concurrent with the strong EMU emissions of Tb^(3+).Our findings might stimulate new concepts for manipulating upconversion emissions of lanthanide NCs. | Dan Xu Jin Xu Xiaoying Shang Shaohua Yu Wei Zheng Datao Tu Renfu Li Xueyuan Chen | 2022 | CCS Chemistry2022，4，6： | 0 |
