With the rapid development of next-generation sequencing technologies and bioinformatics, over 50 ray-finned fish genomes by far have been sequenced with high quality. The genomic work provides abundant genetic resources for deep understanding of divergence, evolution and adaptation in the fish genomes. They are also instructive for identification of candidate genes for functional verification, molecular breeding, and development of novel marine drugs. As an example of other omics data, the Fish-T1 K project generated a big database of fish transcriptomes to integrate with these published fish genomes for potential applications. In this review, we highlight the above-mentioned recent investigations and core topics on the ray-finned fish genome research, with a main goal to obtain a deeper understanding of fish biology for theoretical and practical applications.

Perovskite solar cells(PSCs) have demonstrated excellent photovoltaic performance which currently rival the long-standing silicon solar cells’ efficiency. However, the relatively poor device operational stability of PSCs still limits their future commercialization. Binary sulfide is a category of materials with promising optoelectrical properties, which shows the potential to improve both the efficiency and stability of *** we demonstrate that the inorganic tin monosulfide(Sn S) can be an efficient dopant in 2,2’,7,7’-tet rakis(N,N-di-p-methoxy-phenylamine)-9,9’-spirobifluorene(spiro-OMe TAD) to form a composite hole transport layer(HTL) for PSCs. Sn S nanoparticles(NPs) synthesized through a simple chemical precipitation method exhibit good crystallization and suitable band matching with the perovskites. The introduction of Sn S NPs in Spiro-OMTAD HTLs enhanced charge extraction, reduced trap state density, and shallowed trap state energy level of the devices based on the composite HTLs. Therefore, the resulting solar cells employing Sn S-doped spiro-OMe TAD HTLs delivered an improved stabilized power output efficiency of 21.75% as well as enhanced long-term stability and operational stability. Our results provide a simple method to modify the conventional spiro-OMe TAD and obtain PSCs with both high efficiency and good stability.

Multifunctional MgF_2/Polydopamine Coating on Mg Alloy for Vascular Stent Application

引用

Journal of Materials Science & Technology 2015年第7期31卷 733-743页

Mg alloy is of great potential in the application of vascular stent due to its degradation in physical environment and proper mechanical property. However its mechanical integrity does not meet the clinical requirement clue to relatively fast degradation. Besides, in order to accelerate the re- endothelialization of Mg-based stents, it needs surface modification to improve the attachment, growth and adhesion of endothelial cells （ECs）. To solve the main obstacles, an anti-corrosion and quick endothelialization coating was prepared on novel Mg-Zn-Y-Ncl alloy via a simple two-step immersion method in the present study, first in hydrofluoric acid （HF） then in dopamine tris-Hydrochloric acid （tris -HCI） solution. The coating was uniform and thin, which consisted of two layers--the upper was pol- yclopamine （PDA） layer and the lower was MgF2 layer. The alloy with the coating demonstrated dramatic corrosion resistance enhancement in vitro by immersion test and electrochemical test. Moreover the HF- PDA-treated Mg alloy exhibited great performance of cell adhesion and proliferation. The coating created a favorable environment for ECs to have a competitive advantage over vascular smooth muscle ceils （VSMCs）, which was preferable for re-enclothelialization. The results suggest that HF-PDA-treatecl Mg -Zn-Y-Nd alloy has great potential in the application of vascular stent and the surface coating method is of great aPPlication value in biodegraclable Mg alloy stent clue to its simplicity and effectiveness.

A kind of sandwich-like NiCo_2O_4/rGO/NiO heterostructure composite has been successfully anchored on nickel foam substrate via a three-step hydrothermal method with successive annealing treatment. The smart combination of NiCo_2O_4, reduced graphene oxide(rGO), and NiO nanostructure in the sandwich-like nano architecture shows a promising synergistic effect for supercapacitors with greatly enhanced electrochemical performance. For serving as supercapacitor electrode, the NiCo_2O_4/rGO/NiO heterostructure materials exhibit remarkable specific capacitance of 2644 mF cm^(-2)at current density of 1 mA cm^(-2),and excellent capacitance retentions of 97.5% after 3000 cycles. It is expected that the present heterostructure will be a promising electrode material for high-performance supercapacitors.

Influence of the extraction parameters on the cytotoxicity test results of Mg materials

引用

Progress in Natural Science:Materials International 2014年第5期24卷 507-515页

作者： Xiaoli Liu Tingfei Xi Yudong Zheng School of Materials Science and Technology University of Science and Technology Beijing Center for Biomedical Materials and Tissue Engineering Academy for Advanced Interdisciplinary Studies Peking University shenzhen Key Laboratory of Human Tissue Regeneration and Repair Shenzhen Institute Peking University

Recently more and more researchers query the predictability of cytotoxicity results of biomedical Mg alloys obtained according to ISO 10993 due to significant difference between in vitro and in vivo corrosion. This study aimed to observe the influence of different extraction parameters(time, volume/surface ratio and medium composition) on cytotoxicity results and illustrate whether more predictable results could be obtained by adjusting the extraction parameters. The results showed that longer extraction time and smaller extraction volume/surface ratio improve the sensitivity of screening Mg materials by making inferior Mg materials release relatively more ions to the extract; and more predictable results could not be obtained by the way of simply adding bovine serum albumin(BSA) into the extraction medium to the same level in vivo or simply using fetal bovine serum(FBS) directly as extraction medium, since BSA and FBS accelerated the corrosion of Mg materials during extraction and they affected the cells’ health states during the test. In order to get more predictable results, in our opinions, it is necessary to establish a database of primary cells’ hazards(metal ions, p H and H2gas) tolerance and a set of in vitro corrosion test with high similarity in vivo, which is very difficult to realize now however.

Shear Deformation Behaviors of Sn3.5Ag Lead-free Solder Samples

引用

Journal of Materials Science & Technology 2013年第5期29卷 471-479页

作者： Jing Han Hongtao Chen Mingyu Li Chunqing Wang Department of Materials Science and Engineering Shenzhen Graduate SchoolHarbin Institute of Technology State Key Laboratory of Advanced Welding Production Technology Harbin Institute of Technology

In this study, shear tests have been performed on the as-reflowed Sn3.5Ag solder bumps and joints to investigate the deformation behavior of Sn3.5Ag lead-free solder samples. Scanning electron microscopy （SEM） was employed to characterize the microstructures of the samples and orientation imaging microscopy （OIM） with electron backscattered diffraction （EBSD） in SEM was used to obtain crystallographic orientation of grains to provide a detailed characterization of the deformation behavior in Sn3.5Ag solder samples after shear tests. The deformation behavior in solder samples under shear stress was discussed. The experimental results suggest that the dynamic recrystallization could occur under shear stress at room temperature and recrystallized grains should evolve from subgrains by rotation. Compared with that of non-recrystallized and as-reflowed microstructures, the microhardness of the recrystallized microstructure decreased after shear tests.

作者：许宗祥 Roy V.A.L Department of Chemistry South University of Science and Technology of China Center Of Superdiamond and Advanced Films (COSDAF) Department of Physics and Materials ScienceCity University of Hong Kong

It is found that ultrathin poly（3-hexylthiophene）（P3HT） film with a 2.5 nm-thick layer exhibits a higher mobility of 5.0× 10-2 cm2/V-s than its bulk counterpart. The crystalline structure of the as-fabricated ultrathin P3HT layer is verified by atomic force microscopy as well as grazing incidence X-ray diffraction. Transient measurements of the as-fabricated transistors reveal the influence of the interface traps on charge transport. These results are explained by the trap energy level distribution at the interface manipulated by layers of polymer film.
