Ultra-thin films of hexyltriphenylphosphonium-TCNQ(1:1) complex were formed on various substrates by Langmuir-Blodgett technique, where hexyliriphenylphosphonium- TCNQ(1:1) complex was synthesized by attaching hexyltriphenylphosphonium group to TCNQ. The reaction product was identified with FT-IR, and UV-Vis absorption spectroscopies. The formation of ultra-thin films of hexyltirphenylphosphonium- TCNQ(1:1) complex was confirmed also by FT-IR, and UV/Vis absorption spectroscopies.

Purpose: This study was designed to evaluate outcomes of transperitoneal and retroperitoneal approaches in laparoscopic adrenalectomy for resectable adrenal mass. Methods: Laparoscopic adrenalectomy was performed on 134 patients with resectable adrenal mass between February 2004 and February 2009. We retrospectively reviewed the results of transperitoneal approach (TPA) and that of retroperitoneal approach (RPA) in terms of clinicopathologics and surgical outcomes. Results: 80 patients (39 men and 41 women) underwent TPA, of them, 68 were located in left and 12 were located in right. 54 patients (25 men and 29 women) underwent RPA. In RPA group, 9 were located in left and 45 were located in right. There were no difference in clinicopathologics (including age, gender and BMI), in postoperative complication and in mortality. Operative time was shorter, blood loss was smaller and less pain killers was administered in RPA group (p<0.05). Conclusion: Our study shows that both approach (TPA and RPA) have a good peri-operative outcomes, but RPA is less painful and has a shorter operative time than TPA. It is needed to choose operative approach based on certain patient selection criteria for high patient and surgeon satisfaction.

Ultra thin films of Tetra-3-hexadecylsulphamoylcopperphthalocyanine(HDSM-CuPc) were formed on various substrates by Langmuir-Blodgett method, where HDSM-CuPc was synthesized by attaching long-chain alkylamine(hexa-decylamine) to CuPc. The reaction product was identified with FT-IR, UV-visible absorption spectroscopies, elemental analysis and thin layer chromatography. The formation of Ultrathin Langmuir-Blodgett(LB) films of HDSM-CuPc was confirmed by FT-IR and UV-visible spectroscopies. A quartz piezoelectric crystal coated with LB films of HDSM-CuPc was examined as a gas sensor for NO_2 gas. HDSM-CuPc LB films were transferred to a quartz crystal microbalance(QCM) in the form of Z-type multilayers. Response characteristics of film-coated QCM to NO_2 gas concentrations over a range of 100~600ppm have been tested with a thickness of 5~20 layers of HDSM-CuPc. Changes in frequency by the response time was slow.

Response characteristics of film-coated QCM to NO₂ gas concentrations over a range of l00~600ppm have been tested with a thickness of 5~20 layers of HDSM-CuPc. Changes in frequency by adsorption of NO₂ were increased with the number of LB layers and NO₂ concentration, but the response time was slow.
