Carbon membranes have high adsorption capacitiy with respect to its incredible properties such as unique structural, electronic, optoelectronic, semiconductor, mechanical, chemical and physical. Carbon nanotube (CNT) membranes because of its high permeance have been recently developed.Great attention has been currently paid to the field of fabrication methods capable of producing uniform, well-aligned and monodispersed CNT array. Current research concerns with fabrication of vertically aligned CNT membrane in order to remove heavy metal ion presents in waste water. For this purpose, CNTs are vertically grown up through the holes of anodic aluminium oxide (AAO); as a template, by chemical vapor deposition (CVD) of acetylene gas.In this work a few heavy metals such as Pb (II), Cu (II) and Cd (II) has been examined for checking the perfomance of membrane in aqueous solution. The morphological properties of the aligned CNT membrane were investigated with scanning electron microscopy (SEM). The method has simple technology, low cost, and easy reproduction.

Purpose Sleep disturbances are very common among cancer patients, and they need more support in this regard. More access to technology has provided opportunities to use virtual teaching methods to train and support cancer patients. This study aimed to investigate the effect of supportive-educational intervention (SEI) through virtual social networks (VSNs) on the sleep quality and the severity of insomnia of cancer patients. Methods The study was conducted on 66 patients with cancer, intervention (n = 33) and control (n = 33) groups(CONSORT). Intervention group received supportive-educational intervention on sleep for two months through virtual social networks(VSNs). All participants completed the Pittsburgh Sleep Quality Index and insomnia severity index(ISI) before, and after the intervention. Results The mean scores of sleep quality (p = .001) and insomnia severity (p = .001) in the intervention group had a statistical significant decrease. Moreover, quality, latency, duration, efficiency, disturbances of sleep, and daytime dysfunction showed significant improvement in the intervention group, every two times after the intervention (P < .05). However, the participants’ sleep quality deteriorated progressively in the control group (p = .001). Conclusions Supportive-Educational Intervention(SEI) through VSNs can be an effective method to improve the sleep quality and decrease insomnia severity of patients with cancer.
