In this letter, the facial noncovalent adsorption of single-stranded DNA (ssDNA) provided single-walled carbon nanotubes (SWNTs) with biofunctionality while their superior properties were retained. In this case, we innovatively demonstrated the feasibility of employing the negative surface charge of ssDNA-SWNTs to realize layer-by-layer electrostatic self-assembly. On the basis of such a sandwichlike structure, an applicable glucose microbiosensor with direct electrochemistry and high performance was fabricated. The proposed protocol provided an ideal platform for various sensing applications, and might have profound influence on related nanotechnology. © 2014 American Chemical Society.

In this White Paper we present the potential of the Enhanced X-ray Timing and Polarimetry (eXTP) mission for determining the nature of dense matter;neutron star cores host an extreme density regime which cannot be replicated in a terrestrial laboratory. The tightest statistical constraints on the dense matter equation of state will come from pulse profile modelling of accretion-powered pulsars, burst oscillation sources, and rotation-powered pulsars. Additional constraints will derive from spin measurements, burst spectra, and properties of the accretion flows in the vicinity of the neutron star. Under development by an international Consortium led by the Institute of High Energy Physics of the Chinese Academy of Science, the eXTP mission is expected to be launched in the mid 2020s.

Using first-principles evolutionary simulations, we have systematically investigated phase stability in the Hf-O system at pressure up to 120 GPa. new compounds Hf5O2,Hf3O2, HfO, and HfO3 are discovered to be thermodynamically stable at certain pressure ranges. Two new high-pressure phases are found for Hf2O: one with space group Pnnm and anti-CaCl2-type structure, another with space group I41/amd. Pnnm-HfO3 shows interesting structure, simultaneously containing oxide O2− and peroxide [O-O]2− anions. Remarkably, it is P6¯2m-HfO rather than OII-HfO2 that exhibits the highest mechanical characteristics among Hf-O compounds. Pnnm-Hf2O, Imm2-Hf5O2,P3¯1m−Hf2O, and P4¯m2−Hf2O3 phases also show superior mechanical properties; theoretically these phases become metastable phases to ambient pressure and their properties can be exploited.

Effect of different forms of silica on sintering, microstructure and properties of borosilicate glass/Al₂O₃ composites

Journal Wuhan University of technology, materials Science Edition 2014年第1期29卷 58-64页

作者： Liu, Ming Zhou, Hongqing Zhu, Haikui Yue, Zhenxing Zhao, Jianxin College of Materials Science and Engineering Nanjing University of Technology Nanjing 210009 China Department of Materials Science and Engineering Luoyang Institute of Science and Technology Luoyang 471023 China State Key Laboratory of New Ceramic and Fine Processing Tsinghua University Beijing 100084 China

The effects of the introduction of silica glass and silica ceramic into Ca-Al-B-Si-O glass/ Al2O3 composites on decreasing the shrinkage and the dielectric constant of samples were investigated by FTIR, DSC, XRD and SEM. The results show that silica ceramic filler can better improve the formation of Si-O-Si network in the composites under high temperature, which leads to increased continuity of glass network at high temperature, and deduces the increase of viscosity of composites and further results in the decrease in the shrinkage of samples. Densification, three-point strength, and dielectric constant of samples decrease with the increase of silica glass or silica ceramic content. By contrast, Ca-Al-B-Si-O glass/Al2O3 composites with 4 wt% silica ceramic exhibit better properties of a bulk density of 2.81 g·cm^-3, a porosity of 0.3%, a 3dp value of 202 MPa, a É r value of 7.41, a tan δ value of 8.3×10^-4 at 10 MHz and a well matching with Ag electrodes. This material is suitable to be used as the LTCC material for the application in wireless communications. © 2014 Wuhan University of technology and Springer-Verlag Berlin Heidelberg.
