Monolayers based on the novel multifunctional compound K29 (the amphiphilic and photosensitive derivative of dithiacrown-ethers) were obtained and investigated. The studied ion-selective and photosensitive properties of K29 in monolayers demonstrated its ability to form complexes with mercury cations which were detected by significant changes in the K29 monolayer isotherms and absorption spectr...

We demonstrated self-patterned solution-processed amorphous oxide semiconductor thin-film transistors (TFTs) using photosensitive sol-gels. The photosensitive sol-gels were synthesized by adding β-diketone compounds, i.e., benzoylacetone and acetylacetone, to sol-gels. The chemically modified photosensitive sol-gels showed a high optical absorption at specific wavelengths due to the formation o...

A photosensitive insulin derivative was synthesized by reacting radioactive iodinated bovine insulin with N-hydroxysuccinimide ester of 4-azidobenzolic acid. The photo-sensitivity and specificity of this insulin derivative were established by its covalent nonspecific cross-link to albumin and its covalent specific cross-link to the heavy and light chains of anti-insulin immunoglobulin. Plasma m...

3D television (TV) and cinema have experienced a recent surge in popularity aided in part by the success of films such as "Toy Story 3" and "Avatar". In parallel with this trend there have been increasing concerns about the safety of 3D TV and cinema for patients with photosensitive epilepsy. General practitioners, paediatricians and neurologists are being consulted about their opinions on the ...

Television viewing is the most frequent cause of photogenic attacks in daily life. In the present study, we examined 48 photosensitive children and adolescents to find out: 1) whether hypersynchronous activity is induced less often by viewing a PC monitor than a television screen and 2) whether certain images are more likely to cause hypersynchronous activity than others. All subjects were test...

The photosensitive nature of a thermally evaporated Cu/p-SnSe thin film Schottky junction.

Life on earth is subject to alternating cycles of day and night imposed by the rotation of the earth. Consequently, living things have evolved photodetective systems to synchronize their physiology and behavior with the external light-dark cycle. This form of photodetection is unlike the familiar "image vision," in that the basic information is light or darkness over time, independent of spatia...

We present results of electrical and photoelectrical measurements on two types of Al/porous silicon (PS)/monocrystalline silicon (c-Si)/Al sandwich structures with thin and thick PS layers obtained by stain etching. Current-voltage characteristics and photosensitivity spectra indicate that for structures with a thin PS layer the photosensitivity is determined by PS/c-Si heterojunctions (HJ), wh...
