ISONICOTINIC ACID-LIGATED COBALT (II) PHTHALOCYANINE-MODIFIED TITANIA AS PHOTOCATALYST FOR BENZENE DEGRADATION VIA FLUORESCENT LAMP

The utilization of bis(isonicotinic acid)phthalocyaninatocobalt (II) [CoPc(isa)2] incorporated on TiO2 has been studied as a photocatalyst to degrade benzene vapor under fluorescent lamp (indoor light) conditions.

Figure 4a shows linear sweep voltammetry of the TiO 1.988 N 0.012 photoanode before and after cobalt treatment. After the cobalt treatment, the photocurrent density at 1.23 V RHE increases from 0.23 mA/cm 2 (without cobalt) to 0.61 mA/cm 2 (60% higher than the unmodified TiO 2 s[r]

Ewing sarcoma is an aggressive, highly metastatic primary bone and soft tissue tumor most frequently occurring in the bone of young adolescents. Patients, especially those diagnosed with a metastatic disease, have a poor overall survival.

Cytotoxicity assay
Caco-2 cells were seeded as before and treated with QDs in the same conditions. After 4 h incubation, the QD containing solution was aspirated out of the dishes and the cells were washed three times with PBS. 50 μ g of Calcein AM were dissolved in 50 μ L of dimethyl sulf-[r]

Highest PCB degradation was obtained with pH 7 as shown in Fig. 5. This observation coincides with the report of Alnaizy and Akgerman (2000) on the degradation of phenolic compounds. After 60 minutes of irradiation, 76% PCB degradation was obtained with pH 3, 78% wit[r]

Discussion
The most extensively used diagnostic methods for KHV are cell culture and PCR. These techniques, however, require a relatively long time to produce results or are not practical for commercial producers, retailers, and regula- tors because of the equipment and expertise nee[r]
