aligned and random nanocomposite nanofibrous scaffolds were electrospun from polycaprolactone (pcl), poly (vinyl alcohol) (pva) and hydroxyapatite nanoparticles (nha). the morphology and mechanical characteristics of the nanofibers were evaluated using scanning electron microscopy and tensile testing, respectively. scanning electron microscopy revealed fibers with an average diameter of 123 ± 3...

The ground plane has never been considered as a degree of freedom to be used for chipless radio frequency (RF) identification (RFID) tag design purposes. For the first time, we show that interaction with can exploited achieve challenging designs, such depolarizing insensitive orientation (i.e., nonzero cross polar any roll angle). principle relies on perturbation symmetry merely one microstrip ...

The microstructure of a (001) κ-Ga 2 O 3 thin film grown on (−201) β-Ga substrate by mist CVD was investigated using automated crystal orientation mapping scanning transmission electron microscopy.

A new tool for studying the process of carbon nanotube chemical vapor deposition (CVD) synthesis is described. By rotating the substrate in situ during the CVD process, the orientation of floating nanotubes with respect to the substrate is changed by interaction with the gas stream. Nanotubes lying on the surface of the substrate, however, will maintain their relative orientation. As a result d...

Nickel oxide (NiO) semiconductors thin films were prepared by e-beam evaporation technique at different substrate temperatures ranging from room temperature to 400 C on glass substrate. Glancing incident X-ray diffraction depict that with the increases in substrate temperature the preferred orientation changes from (111) to (200) direction. Atomic force microscopy was used to investigate the su...
