The C60 fullerenes are fascinating objects and even many years after their discovery the photo-physics of C60 is still full of surprises. With their well defined, highly symmetric structure the fullerenes are challenging model systems and examples of an interface between atoms or small molecules and the solid state. The 60 delocalized π electrons in the C60 fullerene give rise to interesting bu...

We present photosensitivity in large area physical vapour deposited mono and bi-layer MoS2 films. Photo-voltaic effect was observed in single layer MoS2 without any apparent rectifying junctions, making device fabrication straightforward. For bi-layers, no such effect was present, suggesting strong size effect in light-matter interaction. The photo-voltaic effect was observed to highly directio...

The photo-physical properties of Eu-SWCNTs indicate that intrinsic excitonic properties of SWCNTs sensitize the lanthanoid element europium (Eu) to emit time-resolved red luminescence.

There are many photo-protective measures adopted for protection from the solar radiation especially the UV radiation spectrum, sunscreens being the main agents. Besides the traditional approach of topical use of sunscreens, both chemical and physical, a new approach has emerged to use systemic agents in the form of vitamins and minerals. In this review, we are describing the major aspects relat...

We demonstrate that direct femtosecond laser writing in silver-containing zinc and gallium phosphate glass enables generation of three-dimensional (3D) optical second-order nonlinear microstructures having an χ(2) value about 2.5 times that of quartz. The proposed physical model involves photo-reduction, photo-dissociation, and migration of silver species within the glass matrix. 3D laser-writt...

Photo-degradation is an irreversible alteration in the chemical, mechanical and physical properties of polymers, these alterations are a result photon absorption from sunlight. UV-light considered to be main factor for initiating photo-degradation process polymers. To extend lifetime their durability, overall minimization rate photo degradation protection polymers against environmental factors,...

This paper is a definition of photo elicitation and a history of its development in anthropology and sociology. The view of photo elicitation in these disciplines, where the greatest number of photo elicitation studies have taken place, organizes photo elicitation studies by topic and by form. The paper also presents practical considerations from a frequent photo elicitation researcher and conc...

Recent theoretical progress in understanding the effect of silver nanoparticles on photo-induced orientation of liquid crystalline polymer was reviewed. The observed enhancement of photo-induced rate results from the surface plasmon resonance (SPR) of silver nanoparticles. And the observed reducing phenomena are attributed to the interaction between materials and silver nanoparticles. And then ...
