| 1 | TiO_(2) Nanocrystals Grown on Graphene as Advanced Photocatalytic Hybrid Materials显示文摘A graphene/TiO_(2) nanocrystals hybrid has been successfully prepared by directly growing TiO_(2) nanocrystals on graphene oxide(GO)sheets.The direct growth of the nanocrystals on GO sheets was achieved by a two-step method,in which TiO_(2) was first coated on GO sheets by hydrolysis and crystallized into anatase nanocrystals by hydrothermal treatment in the second step.Slow hydrolysis induced by the use of EtOH/H2O mixed solvent and addition of H2SO4 facilitates the selective growth of TiO_(2) on GO and suppresses growth of free TiO_(2) in solution.The method offers easy access to the GO/TiO_(2) nanocrystals hybrid with a uniform coating and strong interactions between TiO_(2) and the underlying GO sheets.The strong coupling gives advanced hybrid materials with various applications including photocatalysis.The prepared graphene/TiO_(2) nanocrystals hybrid has superior photocatalytic activity to other TiO_(2) materials in the degradation of rhodamine B,showing an impressive three-fold photocatalytic enhancement over P25.It is expected that the hybrid material could also be promising for various other applications including lithium ion batteries,where strong electrical coupling to TiO_(2) nanoparticles is essential. | Yongye Liang Hailiang Wang Hernan Sanchez Casalongue Zhuo Chen Hongjie Dai | 2010 | Nano Research2010，3，10： | 57 |

| 3 | Revealing the hidden performance of metal phthalocyanines for CO2 reduction electrocatalysis by hybridization with carbon nanotubes显示文摘Metal phthalocyanines(MePcs)have been considered as promising catalysts for CO2 reduction electrocatalysis due to high turnover frequency and structural tunability.However,their performance is often limited by low current density and the performance of some systems is con troversial.Here,we report a carb on nano tube(CNT)hybridizati on approach to study the electrocatalytic performa nee of MePcs(Me=Co,Fe and Mn).MePc molecules are anchored on CNTs to form the hybrid materials without noticeable molecular aggregations.The MePc/CNT hybrids show higher activities and better stabilities than their molecular counterparts.FePc/CNT is slightly less active than CoPc/CNT,but it could deliver higher Faradaic efficiencies for CO production at low overpotentials.In contrast,the catalytic performance of MePc molecules directly loaded on substrate is hin dered by molecular aggregati on,especially for FePc and MnPc.Our results suggest that carbon nano tube hybridization is an efficient approach to construct advaneed MePc electrocatalysts and to understand their catalytic performance. | Zhan Jiang Yang Wang Xiao Zhang Hongzhi Zheng Xiaojun Wang Yongye Liang | 2019 | Nano Research2019，12，9： | 9 |
| 4 | A bio-inspired O2-tolerant catalytic CO2 reduction electrode显示文摘The electrochemical reduction of CO2 to give CO in the presence of O2 would allow the direct valorization of flue gases from fossil fuel combustion and of CO2 captured from air. However, it is a challenging task because O2 reduction is thermodynamically favored over that of CO2. 5% O2 in CO2 near catalyst surface is sufficient to completely inhibit the CO2 reduction reaction. Here we report an O2-tolerant catalytic CO2 reduction electrode inspired by part of the natural photosynthesis unit. The electrode comprises of heterogenized cobalt phthalocyanine molecules serving as the cathode catalyst with >95% Faradaic efficiency(FE) for CO2 reduction to CO coated with a polymer of intrinsic microporosity that works as a CO2-selective layer with a CO2/O2 selectivity of $20. Integrated into a flow electrolytic cell, the hybrid electrode operating with a CO2 feed gas containing 5% O2 exhibits a FECOof 75.9% with a total current density of 27.3 mA/cm^2 at a cell voltage of 3.1 V. A FECO of 49.7% can be retained when the O2 fraction increases to 20%. Stable operation for 18 h is demonstrated. The electrochemical performance and O2 tolerance can be further enhanced by introducing cyano and nitro substituents to the phthalocyanine ligand. | Xu Lu Zhan Jiang Xiaolei Yuan Yueshen Wu Richard Malpass-Evans Yiren Zhong Yongye Liang Neil BMcKeown Hailiang Wang | 2019 | Science Bulletin2019，64，24： | 5 |
| 5 | A theranostic agent for cancer therapy and imaging in the second nearinfrared window显示文摘Thera no stic nano particles are integrated systems useful for simulta neous diag nosis and imaging guided delivery of therapeutic drugs, with wide ranging pote ntial applicati ons in the clinic. Here we developed a thera no stic nan oparticle (~24 nm size by dynamic light scatteri ng) p-FE-PTX-FA based on polymeric micelle encapsulating an organic dye (FE) fluorescing in the 1,000-1,700 nm second near-infrared (NIR-Ⅱ) window and an an ti-ca ncer drug paclitaxel. Folic acid (FA) was conjugated to the nan oparticles to afford specific binding to molecular folate receptors on muri ne breast can cer 4T1 tumor cells. In vivo, the nan oparticles accumulated in 4T1 tumor through both passive and active targeting effect. Under an 808 nm laser excitation, fluorescence detection above 1,300 nm afforded a large Stokes shift, allowing targeted molecular imaging tumor with high signal to background ratios, reaching a high tumor to normal tissue signal ratio (T/NT) of (20.0±2.3). Further, 4T1 tumors on mice were completed eradicated by paclitaxel released from p-FE-PTA-FA within 20 days of the first injection. Pharmacokinetics and histology studies indicated p-FE-PTX-FA had no obvious toxic side effects to major organs. This represented the first NIR-Ⅱ theranostic age nt developed. | Zhuoran Ma Hao Wan Weizhi Wang Xiaodong Zhang Takaaki Uno Qianglai Yang Jingying Yue Hongpeng Gao Yeteng Zhong Ye Tian Qinchao Sun Yongye Liang Hongjie Dai | 2019 | Nano Research2019，12，2： | 4 |
| 6 | Rational Design of High Brightness NIR-II Organic Dyes with S‑D-AD‑S Structure显示文摘CONSPECTUS:Fluorescence bioimaging in the second nearinfrared window(NIR-II,1000−1700 nm)is a superior visualization tool with deeper penetration and higher spatial resolution than the traditional vis/NIR window(400−1000 nm).Developing desirable NIR-II agents with high brightness(high quantum yield(QY)and absorption coefficient),longer emission wavelengths,light stability,and good biocompatibility is a bottleneck that must be crossed in the process of clinical transformation.NIR-II organic agents attract more attention because of their good biocompatibility.Researchers are committed to develop small organic molecules with an adjustable narrow band gap to emit longer NIR-II wavelengths.However,the reduced band gap of molecular fluorophores generally triggered interactions between the conjugated skeleton and other molecules,leading to a decreased fluorescence QY,especially quenching in aqueous systems.Aiming to enhance NIR-II fluorophores’brightness in aqueous systems,the molecular engineering of a shielding and donor unit is introduced in NIR-II fluorophores,and these molecules are composed of a shielding unit,donor(s),acceptor,donor(s),shielding unit(S-D-A-D-S)structure.We found that the donor’s steric hindrance brings about a molecular twist that can be tuned with electrostatic potential surfaces and the donor’s hydrophobic effects,which can reduce water molecules approaching the excitation center.In addition to the protective effect of the electron shielding units,these changes can be weakened by the interactions between water and fluorophore molecules,which is beneficial to the stability of excited states for fluorophore brightness maintained in watersoluble environments.However,the molecular torsion will reduce intramolecular charge transfer(ICT),the weakened transition from the ground state to the excited state(S_(0)−S_(1)),leading to an undesired decrease in the absorption coefficient.Thus,it is necessary to develop molecular engineering to improve emission QY without sacrificing the absorption coefficient.Therefore,bright NIR-II fluorophores need to have a rational balanced donor unit,which can have decreased backbone distortion to strengthen ICT and better protect the conjugated backbone to reduce the water molecule effect,resulting in improvements to the QY and absorption coefficient simultaneously.In this Account,we will present a concise summary and analysis of the rational molecular design of S-D-A-D-S structural NIR-II fluorophores for tunable enhanced QY and absorption coefficients based on the shielding and donor engineering strategy.We expect that this Account will trigger more research interest to explore the inspiring performance of S-D-A-D-S structural NIR-II fluorophores and employ them in bioimaging to promote the process of clinical transformation. | Qinglai Yang Huilong Ma Yongye Liang Hongjie Dai | 2021 | Accounts of Materials Research2021，2，3： | 3 |

| 14 | Scriptaid affects histone acetylation and the expression of development-related genes at different stages of porcine somatic cell nuclear transfer embryo during early development显示文摘Although the somatic cell nuclear transfer(SCNT) technique has been used extensively for cloning and generating transgenic pigs,the cloning efficiency is still very low.It has been proposed that the low efficiency of this technique is the result of incomplete epigenetic reprogramming and abnormal gene expression during early embryonic development.In this study,we investigate the effect of Scriptaid,a low-toxicity histone deacetylase inhibitor,on the developmental competence of porcine SCNT embryos.We found that treating SCNT embryos with 500 nmol/L Scriptaid for 15 h after activation significantly enhanced the blastocyst formation rate(27.7%) compared with the untreated group(control)(12.2%,P<0.05).Using an immunofluorescence technique to measure the average fluorescence intensity,we also found that treating SCNT embryos with Scriptaid increased the level of histone acetylation on histone H3 at lysine 14(acH3K14).Furthermore,treating embryos with Scriptaid increased the expression level of three genes that play important roles during embryonic development(Oct4,Klf4 at the blastocyst stage and Nanog at the 4-cell stage).Moreover,the expression level of the apoptosis-related gene Caspase-3 was significantly lower in the Scriptaid-treated SCNT embryos compared with the control SCNT embryos at the 4-cell and blastocyst stages.In conclusion,these results indicate that Scriptaid treatment improves the development and nuclear reprogramming of porcine SCNT embryos. | ZHOU Yan HUANG YongYe XIE WanHua SONG Qi JI Yuan ZHANG YanPing OUYANG HongSheng LAI LiangXue PANG DaXin TANG XiaoChun | 2013 | Chinese Science Bulletin2013，58，18： | 1 |
