| 1 | Designing the mechanical properties of peptide-based supramolecular hydrogels for biomedical applications显示文摘Hydrogels are a class of special materials that contain a large amount of water and behave like rubber.These materials have found broad applications in tissue engineering,cell culturing,regenerative medicine etc.Recently,the exploration of peptide-based supramolecular hydrogels has greatly expanded the repertoire of hydrogels suitable for biomedical applications.However,the mechanical properties of peptide-based hydrogels are intrinsically weak.Therefore,it is crucial to develop methods that can improve the mechanical stability of such peptide-based hydrogels.In this review,we explore the factors that determine or influence the mechanical stability of peptide-based hydrogels and summarize several key elements that may guide scientists to achieve mechanically improved hydrogels.In addition,we exemplified several methods that have been successfully developed to prepare hydrogels with enhanced mechanical stability.These mechanically strong peptide-based hydrogels may find broad applications as novel biomaterials.It is still challenging to engineer hydrogels in order to mimic the mechanical properties of biological tissues.More hydrogel materials with optimal mechanical properties suitable for various types of biological applications will be available in the near future. | LI Ying QIN Meng CAO Yi WANG Wei | 2014 | Science China(Physics,Mechanics & Astronomy)2014，57，5： | 2 |
| 2 | 磁性纳米粒子MFe_2O_4的制备及其磁性能显示文摘为探究Fe_3O_4类磁性纳米粒子磁性能的优劣,采用水热合成法,将相同摩尔比例的Co、Nd、Ce、La和Ni掺杂到Fe_3O_4中,形成具有通式MFe_2O_4的磁性纳米粒子。通过X射线衍射(XRD)、扫描电子显微镜(SEM)、能谱(EDS)、动态激光散射粒径(DSL)和振动样品磁强(VSM)测试,分析了纳米粒子的结构、形貌、元素组成、粒径以及磁性能。结果表明,水热合成法可成功地将Co、Nd、Ce、La和Ni掺杂到Fe_3O_4主晶当中,形成圆形结构纳米粒子,粒子分散性好。其中,CoFe_2O_4的粒径最大,结晶能力最强,使得其具有较高的饱和磁化强度和极高的矫顽力,因此硬磁性能好。3组稀土(Nd、Ce和La)掺杂的纳米粒子中,NdFe_2O_4的粒径最小,同时较高的饱和磁化强度和极低的矫顽力使其具备优异的软磁材料性能。 | 宋晓蕾 余媛 祁珍明 王春霞 葛明桥 | 2018 | 东华大学学报(自然科学版)2018，44，3： | 2 |
| 3 | Effects of Mo on phase structure and up-conversion emissions of Er:Al_2O_3 nanocrystals显示文摘A simple and efficient approach was presented to enhance up-conversion emissions significantly for the Er:Al2O3 nanocrystals by Mo support (Er-Mo:Al2O3) with a 976 nm laser diode excitation. Mo support had evident effects on the phase structure and up-conversion emissions for the Er:Al2O3 nanocrystals, which promoted the -(Al,Er)2O3 transformed to -(Al,Er,Mo)2O3 phase. Compared with the Er:Al2O3, the maximal green and red up-conversion emissions intensities increased about 3×103 and 1.4×102 times for the Er-Mo:Al2O3 nanocrystals, respectively. It suggests that the enhancement of up-conversion emissions is caused by the high excited state energy transfer process from |4I15/2, 3T2> state of the Er3+-MoO42 dimer to the 4F7/2 level of Er3+. | LIU Dan CONG Yan | 2012 | Science China(Physics,Mechanics & Astronomy)2012，55，8： | 1 |
