A method to produce concentrated V4+ ion on V2O5/silica gel.

A Facile Microwave Method to Produce High Crystalline CoFe2O4 Nano-particles

CoFe2O4 have been synthesized via a surfactant assisted gel microwave route with a molar ratio of Fe/Co= 2 and oleic acid (OA) was used as a surfactant. Fourier Transform Infrared spectroscopy (FTIR), X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) were used to consider the structural and morphological properties of CoFe2O4 nano-particles. Results demonstrated that oleic acid is ...

Friction-induced nanofabrication method to produce protrusive nanostructures on quartz

In this paper, a new friction-induced nanofabrication method is presented to fabricate protrusive nanostructures on quartz surfaces through scratching a diamond tip under given normal loads. The nanostructures, such as nanodots, nanolines, surface mesas and nanowords, can be produced on the target surface by programming the tip traces according to the demanded patterns. The height of these nano...

iranian english learners’ perception and personality: a dual approach to investigating influential factors on willingness to communicate

abstract previous studies on willingness to communicate (wtc) have shown the influence of many individual or situational factors on students’ tendency to engage in classroom communication, in which wtc has been viewed either at the trait-level or situational level. however, due to the complexity of the notion of willingness to communicate, the present study suggests that these two strands are ...
