A conventional recovery method has an adverse effect towards unconventional reservoir production. A nanoparticle leads as a primary candidate to develop the unconventional reservoir and it is considered as one of the latest technology in oil and gas industry. Therefore this research is intended to study the effects of Carbon Nanotubes (CNT) towards interfacial tension. Practically MWCNTs were successfully synthesized using CVD technique by pyrolizing toluene and ferrocene in inert gas environment and characterized using X-ray diffraction (XRD) and Transmission Electron Microscope (TEM) in order to understand its structure, shape, size and morphology. The characterization results show the CNTs are in cylindrical shape and well aligned. After characterization, a pendant drop experiment was carried out to further understand the effect of Carbon Nanotubes on Interfacial Tension (IFT). Since the Carbon Nanotubes are very "cloudy" the drop phase could not be identified and the Interfacial Tension was not calculated by the software. Due to this major setback, the Surface Tension was calculated with different concentration.

Background Polyp assessment is multimodal and is vital prior to endoscopic mucosal resection. The size, morphology, site and access (SMSA) score has been validated in specialist endoscopic institutions. this study investigated the ability of this score to predict incomplete endoscopic resection of large colorectal polyps in a district general hospital Methods Consecutive patients undergoing endoscopic mucosal resection of large (≥ 20 mm) colorectal polyps at Worthing Hospital. Clinical, endoscopic and histological data were taken from prospective databases. The primary outcome of the study was to investigate the correlation of the SMSA score with incomplete endoscopic resection. Results Between February 2015 and August 2018, 114 patients underwent colorectal endoscopic mucosal resection. Of these, 67 (59%) were male. The median (interquartile range) age of the study population was 72 years (65–78 years). Some 17 lesions (15%) were pedunculated, 76 (67%) were sessile and 21 were (18%) flat; 84 polyps (77%) were located in the left colon/rectum, with the remainder in the right colon; 51 lesions (45%) were 20–30 mm, 27 (24%) were 30–40 mm and 36 (31%) were greater than 40 mm in diameter. When reclassified into the SMSA score, 9 of the polyps (8%) were level 2, 64 (56%) were level 3 and 41 (36%) were level 4. Incomplete resection was clinically diagnosed in 9/114 (8%). The SMSA score was positively correlated with incomplete endoscopic resection, but not with additional procedure usage, complications or advanced histology. Conclusions Many patients with large polyps can be managed outside of specialist units. This study has validated that the SMSA score was associated with incomplete endoscopic mucosal resection for large polyps in a district general hospital setting.
