Formation of mesostructured titania thin films using isopropoxide precursors
G.Q.M. Lu,I. Kartini,P. Meredith,Diniz da Costa,J. D. Riches 한국물리학회 2004 Current Applied Physics Vol.4 No.2-4
Mesostructured titania thin lms were prepared by an evaporation-induced self-assembly process. The highly acidic sol pre-cursors contained titanium(IV) tetraisopropoxide (TTIP) as a titanium source, a tri-block copolymer Pluronic P123 as a template,and acetylacetonate and HCl as hydrolysis inhibitors. Characteristics of the resultant titania thin lms were studied using X-raydiraction (XRD) analysis, N2-adsorption/desorption analysis, and transmission electron microscopy (TEM). XRD and TEMinvestigations on the as-synthesised lms revealed the appearance of cubic-like, pseudohexagonal, and lamellar mesophases;depending on the amount of water in the sols of lm precursors. Template removal by a calcination process yields high surface area(320360 m2/g) mesoporous materials with crystalline anatase frameworks. Water content also inuences the degree of anatasecrystallinity of the calcined lms. Higher water content resulted in improved anatase crystallinity. These nanostructured materialsare of interest for photocatalysts, photoelectrochemical solar cells and other photonic devices.

The value of PET/CT for cytoreductive surgery selection in recurrent ovarian carcinoma

Objective: To evaluate the value of positron emission tomography/computed tomography (PET/CT) in predicting no residual disease (NRD) after secondary cytoreductive surgery (SCS) compared with MSK criteria, the iMODEL, and the AGO score. Methods: We analyzed 112 patients with platinum-sensitive ovarian carcinoma who underwent SCS. We excluded patients for whom PET/CT was not performed, those without sufficient data, and who received chemotherapy before SCS. Ultimately, 69 patients were included. Results: Variables that correlated with NRD were peritoneal carcinomatosis index (odds ratio [OR]=0.91; 95% confidence interval [CI]=0.83–0.99; p=0.044), European Cooperative Oncology Group Performance Status (ECOG) 0 (OR=8.0; 95% CI=1.34–47.5; p=0.022), and ≤2 lesions by PET/CT (OR=4.36; 95% CI=1.07–17.7; p=0.039). Of the patients with ≤2 lesions by PET/CT, 48 (92.3%) underwent complete SCS. The sensitivity, positive predictive value, negative predictive value, and accuracy of PET/CT for NRD were 85.7%, 92.3%, 33.3%, and 81.2%, respectively. NRD was achieved after fulfilling the MSK criteria, iMODEL and AGO Score in 89.1%, 88.1% and 85.9%, respectively. The accuracy of the MSK criteria, iMODEL, and AGO score in predicting NRD was 87%, 83.3%, and 77.3%, respectively. The PET/CT findings agreed well with the AGO score and iMODEL. The addition of PET/CT to these models increased the NRD rates (92.2%, 91.8%, and 89.4% for MSK+PET/CT, iMODEL+PET/CT, and AGO+PET/CT, respectively), but lowered their accuracy. Conclusion: We observed NRD in 92.3% of patients with ≤2 lesions by PET/CT, with an accuracy of 81.2%. PET/CT did not increase the accuracy of the MSK criteria, iMODEL, or AGO score models.
