PhD thesis - 'Electronic Processes at the Interface of Organic Semiconductors' [PDF]

arXiv, 2017
The thesis focuses on study of optical and photovoltaic properties of iso-type and aniso-type heterostructures based on photosensitive layers of organic semiconductors. The primary attention has been paid on determination of optimal conditions for preparation of organic thin-film structures of methyl substituted perylene pigment, hexathiopentacene and ...

Using Light to Kill Cancer: Development of a Novel Photodynamic Therapy [PDF]

, 2018
Photodynamic therapy (PDT) is a treatment that uses special drugs called photosensitizing agents along with light to kill cancer cells. The specialized drugs only work after they have been activated or turned on by light.
