Objective: To evaluate the efficacy of He-Ne laser in combination with topical clindamycin in the treatment of AV at 108 Military Central Hospital from Oct 2015 to Aug 2016. Subjects and Methods: 61 patients with AV were divided into 2 groups: Group 1: 31 patients were treated with He-Ne laser in combination with topical Clindamycin, Group 2: 30 patients were only treated with topical clindamycin. Laser HE-NE was applied 2 times/week for 6 weeks. Result: After 3 months of treatment Group 1: very good—51.6%, good—48.4%. Group 2: very good—30%, good—50% and moderate—20%. Conclusion: The combination of He-Ne laser with topical clindamycin shows more rapid clinical improvement compared to topical clindamycin alone in the treatment of mild and moderate AV.

Multiwalled carbon nanotubes (MWCNTs) mixed in poly(3-hexylthiophene) (P3HT) were used as a photoactive layer for organic solar cells (OSC). The flexible OSCs of a structure of PET/rGO-P3HT/P3CT/PCBM/LiF-Al were prepared by spincoating. The Uv-vis absorption spectra of the photoactive films and current-voltage characteristics of the OSCs showed the advantage of the composite devices above the pristine-polymeric ones. Under illumination of light with a 100 mW/cm2-powerdensity, the photoelectrical conversion efficiency (PCE) of the OSCs with 3.0 wt% MWNCTs embedded in the photoactive layer possess a value as large as 2.35%. The obtained results suggest further useful applications of the flexible large-area solar cells.

With the aim of producing simple and effective transparent conducting electrodes, the conducting polymer poly(3-hexylthiophene) (P3HT) incorporated with reduced graphene oxide film (rGO) (called rGO-P3HT) was prepared by spin-coating method. Structural, electrical and optical characterization showed that rGO-P3HT films 9.0 wt% P3HT exhibited good stability when exposed to the ambient atmosphere. These composite films of 200 nm thickness possess a sheet resistance and transparency of R□~ 17Ω and T ~ 72%, respectively. Owing to containing conducting polymer, rGO-P3HT-coated glass could be efficiently used in photovoltaic applications, in organic solar cells in particular, with the replacement of the indium tin oxide (ITO) and fluorine tin oxide (FTO) electrodes.

It is know that Multi-walled Carbon Nano Tubes (MWCNTs) are an excellent conduction nanomaterial while Poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT-PSS) is a conductive and transparent polymer. In this paper, we mix MWCNTs with PEDOT-PSS to create a new type of nanocomposite thin film which has both excellent conduction and transparency of each composition materials for applications in electronics and optoelectronics. The nanocomposite is synthesized by modifying MWCNTs in an acid solution then mix with PEDOT-PSS. The field emission scanning electron microscopy (FESEM) images of the fabricated thin film with 0.3 Wt% of MWCNTs show that the diameter and length of the MWCNTs are ca.10-30 nm and 300-500 nm, respectively. Electrical and optical properties of thin film are also investigated: the sheet resistance reaches the minimum value of 36.5 ?/sq with the transparency of ca.76% at the wave length of 600 nm. Furthermore, I-v characteristics of organic light emission diodes (OLEDs) made by the synthesized nanocomposite thin films are analyzed. The ITO/PEDOT-PSS: CNTs/PvK: MEH-PPv/Al multilayer OLED exhibits well improving performance with the work function of 0.8 v corresponding with the current of 0.4 mA while the ITO/PvK: MEH-PPv/Al simple OLED has the work function of 3 v and the current of only 0.01 mA.
