| 3 | Hollow Zn/Co zeolitic imidazolate framework-implanted composite hydrogel for highly efficient uranium extraction from seawater显示文摘Efficient capture of uranium(VI)(U(VI))from seawater is of great significance to the sustainable development of nuclear energy and environmental protection,which is also a serious challenge at present.In this study,hollow Zn/Co zeolitic imidazolate framework(H-ZIF)was decorated on polyacrylamide/sodium alginate(PAM/SA)hydrogel by chelating and covalently crosslinking,and a new type of PAM/SA/H-ZIF hydrogel was synthesized.The combination of PAM/SA and H-ZIF gives PAM/SA/H-ZIF hydrogel excellent mechanical properties,good stability,and abundant surface functional groups,which is beneficial to improving the adsorption properties.The extraction amount of U(VI)by PAM/SA/H-ZIF is 171.14 mg·g^(-1)at C_(0)=99.52 mg·L^(-1)and pH=5.0.The adsorption equilibrium is reached in 120 min and the adsorption process fits well with Langmuir isotherm model and pseudo-second-order rate equation.The PAM/SA/H-ZIF also showed good recyclability and stability after 10 cycles of adsorption-desorption.More importantly,the rate of uranium adsorption is 0.196 mg·g^(-1)·day^(-1)after 30 days,which implies that the PAM/SA/H-ZIF could serve as a potential adsorbent for the development of uranium capture from seawater. | Yucheng Song Xin Ma Huanhuan Tan Zhong Liu Chuntai Liu Changyu Shen Peipei Yang Songwei Li | 2023 | Nano Research2023，16，7： | 0 |
| 4 | Study on Stability of Ion-exchange Resin Catalysts:Ⅱ. Desulfonation during Isobutylene Dimerization显示文摘The performance of ion-exchange resin catalysts during isobutene (IB) dimerization was investigated under different IB contents,temperatures and liquid-volume hourly space velocity (LHSV) using a plug flow reactor in the absence of any selectivity enhancing component.High IB content and temperature resulted in a high conversion and C12 selectivity bu low C8 selectivity.The influence of LHSV was related with the IB content:LHSV had great effect at high IB content,while the performance of ion-exchange resin changed little with LHSV if IB content was low.The effect of water on the stability of resins was also studied.Desulfonation was observed during the C4 dimerization reaction when water was added to the feed.Chlorinated resin was more stable than conventional polystyrene-based resins during the test. | Tan Songwei Wang Hongjun Jiang Hongliang Wang Liqun Wilbert Tsao Lin Xiangzhou | 2011 | China Petroleum Processing & Petrochemical Technology2011，13，1： | 0 |
| 5 | Enhanced photodynamic therapy/photothermo therapy for nasopharyngeal carcinoma via a tumour microenvironment-responsive self-oxygenated drug delivery system显示文摘The hypoxic nature of tumours limits the efficiency of oxygen-dependent photodynamic therapy(PDT).Hence,in this study,indocyanine green(ICG)-loaded lipid-coated zinc peroxide(ZnO_(2))nanoparticles(ZnO_(2)@Lip-ICG)was constructed to realize tumour microenvironment(TME)-responsive self-oxygen supply.Near infrared light irradiation(808 nm),the lipid outer layer of ICG acquires sufficient energy to produce heat,thereby elevating the localised temperature,which results in accelerated ZnO_(2)release and apoptosis of tumour cells.The ZnO_(2)rapidly generates O_(2)in the TME(pH 6.5),which alleviates tumour hypoxia and then enhances the PDT effect of ICG.These results demonstrate that ZnO_(2)@Lip-ICG NPs display good oxygen self-supported properties and outstanding PDT/PTT characteristics,and thus,achieve good tumour proliferation suppression. | Nan Wu Yaqin Tu Guorun Fan Jiahui Ding Jun Luo Wei Wang Chong Zhang Caiyan Yuan Handan Zhang Pei Chen Songwei Tan Hongjun Xiao | 2022 | Asian Journal of Pharmaceutical Sciences2022，17，2： | 0 |
| 6 | Co-delivery of luteolin and TGF-β1 plasmids with ROS-responsive virus-inspired nanoparticles for microenvironment regulation and chemo-gene therapy of intervertebral disc degeneration显示文摘Intervertebral disc degeneration(IDD)is closely related to inflammation and imbalance of synthesis/catabolism of extracellular matrix(ECM)in intervertebral disc(IVD).Considering this,luteolin(LUT),a kind of natural flavonoid with good anti-inflammatory effect and TGF-β1(a gene that promotes the regeneration of ECM)plasmid was co-loaded and co-delivered to nucleus pulposus cells(NPCs).Reactive oxygen species(ROS)responsive cationic copolymer,poly(β-amino ester)-poly(ε-caprolactone)(PBC),with high plasmid DNA(pDNA)compression affinity was synthesized.It can self-assemble into nano-sized polyplexes(pDNA@PBC)with virus-inspired structure and function through which it can transfect pDNA into NPCs with very high efficiency and negligible cytotoxicity.LUT was encapsulated in the hydrophobic core of pDNA@PBC.The co-delivery system,LUT-pTGFβ1@PBC,could enhance the cellular uptake of NPCs and manifest excellent sustained drug release in IVD.Real time quantitative polymerase chain reaction(RT-qPCR)and Western blot experiments reveal that the co-delivery system could inhibit inflammation in NPCs and restore the balance of anabolism and catabolism in vitro by activating TGF/SMAD3 and inhibiting NFkB/p65.Moreover,LUT-pTGF-β1@PBC retards IDD in vivo as detected by radiological and histological methods with good biosafety in rats.LUT-pTGF-β1@PBC may be a promising option for the treatment of IDD. | Yifan Ding Huan Wang Yunyun Wang Long Li Jiahui Ding Caiyan Yuan Tao Xu Haoran Xu Hui Xie Ning Zhu Xin Hu Huang Fang Songwei Tan | 2022 | Nano Research2022，15，9： | 0 |
| 7 | Assembly of a core–shell MOF with stability into polyacrylamide hydrogel for boosting extraction of uranium from seawater显示文摘Efficient and selective extraction of uranium(U(VI))from seawater is essential for sustainable nuclear power production.This study reports a novel adsorbent zeolitic imidazolate framework(ZIF)-67@SiO_(2)-A/polyacrylamide(PAM)which was synthesized by grafting the core–shell metal–organic frameworks(MOFs)-based nanostructures coated with the 3-aminopropyl triethoxysilane(APTES)functionalized SiO_(2)(SiO_(2)-A)onto PAM hydrogel.The SiO_(2) shell was grown on the surface of MOF,which improved the acid-base resistance of MOF.The introduction of ZIF-67@SiO_(2)-A enhances the specific surface area and adsorption efficiency of the PAM.The ZIF-67@SiO_(2)-A/PAM shows remarkable adsorption capacity,fast adsorption kinetics,and good reusability for uranium.It has excellent adsorption property(6.33 mg·g^(-1),30 d)in natural seawater.The X-ray photoelectron spectroscopy(XPS),Fourier transform infrared(FTIR),energy dispersive spectroscopy(EDS)mappings,and density functional theory reveal that the coordination by N and O in ZIF-67@SiO_(2)-A/PAM with uranium is the main mechanism of uranium adsorption.Thus,ZIF-67@SiO_(2)-A/PAM has great potential to capture uranium from natural seawater. | Yucheng Song Huanhuan Tan Shiliang Qin Zhong Liu Chuntai Liu Changyu Shen Peipei Yang Songwei Li | 2024 | Nano Research2024，17，4： | 0 |
