The effect of ionizing radiation on 1O2 production by Ce6 and TiO2

Photosensitizers play a key role in photodynamic therapy as a drug that is activated by light. In this thesis, the effect of ionizing radiation on the generation of singlet oxygen when using photosensitizers (Chlorin e6) and photocatalysts (titanium dioxide) was studied. By using radionuclides and photosensitizers (PS), cells can be killed with...

Analysis of the ability of titanium dioxide nanoparticles to produce singlet oxygen and hydrogen peroxide under ionising radiation

Radiotherapy is a vital component in the treatment of malignancies, with approximately 50 to 70% of cancer patients receiving it at some point. This therapy consists of irradiating the affected body part with an external beam of ionising radiation. A limitation of this technique is its damaging effect on healthy cells surrounding the tumour....

Testing reagents to improve the recovery of ilmenite flotation at Titania A/S

Mineral processing plays an important part in providing our society with much needed resources. These processes, however, could be made much more efficient. Advancements in this field would enable a population to make economical use of its resources. One widely-used ore processing method to separate target minerals from other minerals is froth...
