In order to study the capability of pyrazinium salt derivatives to act as photo-initiators of epoxide monomers, benzyl pyrazinium hexafluoroantimonate (BPH), benzyl 3,5-dimethyl pyrazine hexafluoroantimonate (BDH) and benzyl quinoxalinium hexafluoroantimonate (BQH) were synthesized by the Menschutkin reaction of benzyl bromide with pyrazine, 2,6-dimethyl pyrazine, and quinoxaline, followed by e...

To improve the photo-catalytic degradation of salicylic acid, we reported the fabrication of ordered TiO2 nanotube arrays by a simple and effective two-step anodization method and then these TiO2 nanotubes treated in a methanol solution under UV light irradiation. The TiO2 nanotubes prepared in the two-step anodization process showed better photo-catalytic activity than TiO2 nanotubes prepared ...

Firstly nickel ferrite nanoparticles were synthesized via a simple precipitation method. Then mono-disperse platinum nanoparticles and NiFe2O4@TiO2/Pt nanocomposites were synthesized by a facile sol-gel procedure. The structure, phase and crystallite size of the magnetic and photo-catalyst products were characterized by X-ray diffraction pattern (XRD). The morphology and size of the nanostructu...

The study of current induced by photo-radiating a molecular based device under bias is of fundamental importance to the improvement of photoconductors and photovoltaics. In this technology, electron pumps generate an uphill current that opposes a potential drop and thereby recharges a fuel cell. While the modeled molecular electron pump is completely symmetric, the sign of the photo current is ...

We are describing collaborative authoring technology over the network. One of the components in our authoring technology is photo recommendation system, in which recommended photos will be used in collaborative video authoring and social album. The recommended photos are derived from Facebook, by referring properties of photos currently available on the authoring library. The photo properties i...

Photo-excitation and size-dependent Raman scattering studies on the silicon (Si) nanostructures (NSs) prepared by laser-induced etching are presented here. Asymmetric and red-shifted Raman line-shapes are observed due to photo-excited Fano interaction in the quantum confined nanoparticles. The Fano interaction is observed between photo-excited electronic transitions and discrete phonons in Si N...

Phorigami is a photo browser whose meta-interface visualizes photos by groups according to the analysis of photo contexts. At the core of Phorigami, we proposed a meta-categorization for photo regrouping. This categorization method encompasses the scope of current or expected recognition technologies. Two experiments are conducted by manual classification tasks to study the pertinence of propos...

Platinum-based chemotherapy, although it has been well proven to be effective in the battle against cancer, suffers from limited specificity, severe side effects and drug resistance. The development of new alternatives with potent anticancer effects and improved specificity is therefore urgently needed. Recently, there are some new chemotherapy reagents based on photoactive Re(i) complexes whic...

Background: Cancer is a complex disease with high rate of mortality. At present, Radiation therapy is one of the most common procedures to overcome this situation. The deficiency of conventional method is the lack of fatal dose transmission into the malignant tissue. Hence, uncertain dose may cause regeneration of cancer cells, and relapse of the disease and invasion of the cancer cells to ...

Eurographics 2016 Additional material accompanying paper This document contains a number of additional re-photography examples. Each example consists of a vintage and contemporary photo pair with corresponding line constraints, the quad-based AAAP re-photo of the contemporary photo and a blend of this result with the vintage photo to better appreciate the match.
