High mobility and c-axis orientated ZnO thin films were deposited on glass substrates using RF sputtering method at room temperature. Structural properties of ZnO thin films were investigated by X-ray diffraction (XRD). Surface morphology and roughness were studied with scanning electron microscopy (SEM) and atomic force microscopy (AFM). Electrical… (More)

Background and study aims The pocket-creation method (PCM) is a novel strategy for endoscopic submucosal dissection (ESD). The aim of this study is to determine the efficacy of the PCM for colorectal laterally spreading tumors, non-granular type (LST-NG). Patients and methods The records of 126 consecutive patients with colorectal LST-NG who underwent ESD… (More)
Barrett's adenocarcinoma may occur in multiple sites, and recurrence and metachronous lesions are the major problems with endoscopic resection. Therefore, early detection of such lesions is ideal to achieve complete resection and obtain improved survival rates with minimally invasive treatment. Laser imaging systems allow multiple modalities of endoscopic… (More)
ZnO thin films were successfully grown on flexible plastic substrates using radio-frequency magnetron sputtering method at room temperature. The effects of the sputtering power on the quality of the ZnO films have been investigated. The results show that thin films were polycrystalline, with wurtzite structure and a strong preferred c-axis orientation… (More)
