In this short review, we report the facile fabrication of various interesting multi-component nanostructures including arrays of core-shell nanowires, multiwall nanotubes, segmented nanowires and multilayer stacked nanodisks, using anodized alumina membrane (AAM). We demonstrate that metallic (Cu, Ni and Au) and polymeric (PPV and PPy) one-dimensional (1D) arrays can be readily prepared by electrochemical deposition into the AAM. By optimizing the experimental design and conditions, we developed techniques to produce various multi-component nanostructures such as polymer/metal or metal/metal core-shell nanowires as well as nanotubes, with reasonably good control over both the length and the shell thickness of the nanostructures. Furthermore, we extend this method to make segmented nanowires as well as multilayer stacked nanodisks. Selective functionalization of the segmented nanowires resulted in end-on or side-on adhesion of nanowires during assembly. We illustrate the possibility of utilizing these 1D arrays to present patterns with luminescent and/or magnetic properties at this length scale.

Ultrasonography is widely used to examine reproductive systems in chelonians. Previous studies have described how follicular size is associated with the reproductive stages of yellow-margined box turtles (YMBTs), but our understanding of follicular morphology remains limited. This study describes the different ultrasonographic appearances of preovulatory follicles of these turtles in Taiwan. Randomly selected 28 adult captive female turtles were examined under ultrasonography, weekly from November 2012 to November 2013. The females were divided into ovulatory and non-ovulatory groups with equal number coincidentally based on the whole-year ovulation records. The ovulatory group had significantly larger follicles than the non-ovulatory group (average size of largest follicle, $21.9\pm 2.15$mm versus $14.59\pm 6.74$mm; $p<0.001$). Across both groups, preovulatory follicles exhibited five different morphologies: previtellogenic, homogeneous, heterogeneous, atretic, and multilayered. The multilayered follicles were only observed in the ovulatory group during the late preovulatory (February) and early ovulatory periods (March), resulting in a significant correlation with ovulatory stage ($p=0.016$). During the preovulatory period (from December to February), homogeneous follicles were the predominant follicles in both groups. During the ovulation period, heterogeneous follicles were the main follicles, but only in the ovulatory group. Finally, atretic follicles were predominant in the non-ovulatory group during the early latent period (August). This study provides detailed ultrasonographic data clarifying the correlation between turtle follicular morphology and reproductive cycle. A better understanding of how such morphology is associated with reproductive stages should improve breeding programs in zoos and thus facilitate conservation efforts.

The problem of the propagation of Love waves in multilayers of generalized magneto-thermoelastic materials has been investigated using Haskell matrix method. The dispersion relations for the Love waves are derived for the topmost layer with the help of appropriate conditions. We have observed that there are two wavefronts of Love-type surface waves: the first wavefront is due to the electro-magnetic parameters and the second wavefront appears due to the thermal parameters. The dispersion curves of both these fronts are computed for two and three layers and results are represented graphically. The phase velocity corresponding to first wavefront is non-attenuating, while that of second wavefront is attenuating. The 3D pictures of displacement, conductive temperature and heat flux have shown that transverse displacement, conductive temperature and heat flux are sinusoidal natures.
