A new strategy for enhancing the efficiency of TiO2 dye-sensitized solar cells (DSSCs) by doping foreign ion into TiO2 lattice via sol-gel process is reported. DSSCs are based on a semiconductor (i.e., TiO2), formed between a photo-sensitized anode and an electrolyte. In order to reach high conversion efficiency, it is important to increase the electron injection and optical absorption. One pro...

OBJECTIVE Inflammation is one of the major components of asthma. Our aim was to evaluate the effects of C. sativus extract on total and differential white blood cells (WBC) count in lung lavage fluid (LLF) of ovalbumin-sensitized rats. MATERIALS AND METHODS Forty rats were divided into five groups (n = 8 for each group) as control (C), sensitized with injection and inhalation of ovalbumin (OA...

in order to fabricate transparent tio2 nanotube dye-sensitized solar cells, anodically growth nanotube membranes are detached from ti substrate by a re-anodization method. the membranes are transferred on fto glass by two different methods. at the first one, 100mm ti-isopropoxide is used to make tio2 nanoparticles for adhering tio2 nanotube membranes to fto and in the second one a commercial ti...

a simple, rapid, selective and highly sensitive fluorimetric method for determination of two catecholamines, i.e. norepinephrine (ne) and epinephrine (ep), in serum samples was developed. the method is based on the fluorescence sensitization of terbium (tb3+) by complexation with both catecholamines in the presence of lanthanum (la3+), as a co-cation, and in a na2so3 solution (chemical deoxygen...

We have previously demonstrated that adoptive transfer of alveolar macrophages from allergy-resistant rats to alveolar macrophage-depleted allergic rats prevents airway hyperresponsiveness development, suggesting an important role for alveolar macrophages in asthma pathogenesis. Given that ovalbumin sensitization can modulate alveolar macrophage cytokine production, we investigated the role of ...

BACKGROUND Cross-reactions and co-sensitizations are of great importance in understanding contact allergy and exposure sources. OBJECTIVES To investigate common cross-reactions and co-sensitizations in p-phenylenediamine (PPD)-sensitized and toluene-2,5-diamine (TDA)-sensitized individuals. METHODS From our patch test population, 8036 patients patch tested with the European baseline series ...

A novel phosphorus and oxygen co-doped graphitic carbon nitride (sheetP-O-CNSSA) photocatalyst was successfully synthesized applied for H2 evolution under visible light. In the synthesis process of sheetP-O-CNSSA, supramolecular complex developed by self-assembly copolymerization reaction among melamine, cyanuric acid (CA) trithiocyanuric (TCA) to act as g-C3N4 precursors, while (NH4)2HPO4 P O ...

New donor–π–acceptor pyrimidine-based dyes comprising an amide moiety as anchoring group have been designed. The were synthesized by sequential procedures based on the microwave-assisted Suzuki cross-coupling and bromination reactions. influence of dye structure length π-linker photophysical electrochemical properties photovoltaic effectiveness dye-sensitized solar cells was investigated. An in...
