Matter in intergalactic space is not randomly scattered - it forms a vast network of filamentary structures that make up the ...

The photodegradation of dye pollutants under visible light irradiation in TiO2 dispersions continues to draw considerable attention because of the greater effective utilization of solar energy and its ...

We investigated the dispersion and modal properties of a photonic crystal fiber (PCF) with larger air holes (LAH). The theoretical and numerical results show that large anomalous group-velocity ...
