The control of nanoparticle shape is still a challenge for different hydroxyapatite(HA) preparation *** the present study,silk fibroin with regular nanostructures was firstly prepared and then employed to regulate the mineralization of HA *** morphology and crystal structure of the deposition were investigated by SEM,X-ray diffraction(XRD)and Fourier transform infrared spectroscopy(FTIR).Compared to previous studies in which silk fibroin with different nanostructures was used as template,the present study revealed that the HA nanoparticle shape could be controlled through regulating the nanostructure of silk *** silk nanospheres as template,the shape of HA gradually changed from pin-like structure to rice-like structure following the increase of silk fibroin *** some HA nanofibers were prepared with short silk nanofibers as *** results indicated that it is feasible to achieve the shape control of HA nanoparticles through further regulating the nanostructure of silk fibroin template,which would greatly facilitate the application of HA in different fields.

A new cluster line approach for the composition rule of Laves phase-related BCC solid solution hydrogen-storage alloys was presented. The cluster line in a ternary phase diagram refers to a straight composition line linking a specific binary cluster to the third element. In the Laves phase-related BCC solid solution alloy system such as Ti-Cr-V, Ti-Cr tends to form binary Cr2Ti Laves phase while Ti-V and Cr-V to form solid solutions. This Laves phase is characterized by a close-packing icosahedral cluster Cr7Ti6. A cluster line Cr7Ti6-V is then constructed in this system. Alloy rods with a diameter of 3 mm of compositions along this line were prepared by copper-mould suction method. The alloy structure is found to vary with the V contents. Furthermore, the P-C-T measurements indicate that the cluster-line (Cr7Ti6)1-xVx alloys have large hydrogen storage capacities.

There is evidence that the major safety problem caused by darkness is the pedestrian collisions. Thermal Imaging systems can further reduce this risk. The image binarization is a preprocessing task, it play a very important role in pedestrian detection system. This paper applied the dual thresholds algorithm to process the thermal images for pedestrian segmentation. By a large number of experiments, we get the optimal combinations of the parameters of the algorithm, and get the good image binarization results of the thermal imaging.

The properties of materials have a close connection to their crystal structures. Rare earth (R)-transition metal (T) rich compound are the focus of investigation in the search for new hard magnetic materials. As the basis for the study of stabilized effect of the third component on the formation of RT5 derivative and its influence of the occupied sites on magnetic properties, in this paper, the possible derivative compounds based on the RT5 primitive unit cell of the CaCu5 structure type formed through the ordered or disordered substitution of dumbbell pair 2T atoms for the R atoms at some sites, and the structural relationship between the derivatives and the prototype are summarized.
