Combining the sol-gel method for fiber material production with the granulated silica method for preform assembly results in a robust method that offers a high degree of freedom regarding both the composition and the geometry of the produced fiber. Using ... see more

Experimental evaluation of spectral and power-current (P-I) characteristics of fiber coupled single emitter multimode laser diodes used for development of efficient pumping assembly is reported. Fiber coupled laser diodes emitting around 976 nm are best s... see more

The Lu-Hf method has been used in the investigation of geological samples in order to understand processes and sources of magmatic rocks. This paper discusses the reference materials GJ-01, 91.500 and Mud Tank isotopic composition by LA-ICP-MS to investig... see more

Gadolinium-doped nanoparticles (NPs) are regarded as promising luminescent probes. In this report, we studied details of toxicity mechanism of low doses of NaGdF4-based fluorescent nanoparticles in activated RAW264.7, J774A.1 macrophages. These cell lines... see more

An early success in low temperature superconductor technology has led to the development of a number of high temperature superconductor (H TS) materials, which have critical temperature above 77 K. When the temperature of a solid is lowered below critical... see more

The synthesis of TiO2 co-doped by (Ce, Yb) rare earth couple has been realized. This couple of rare earth can convert a high-energy photon to two low energy photons to enhance the energy efficiency of silicon solar cells. The undoped, 2% Ce doped- and (2%... see more

Synthesis and characterization of Cu-doped zirconium titanateas a potential visible-light responsive photocatalyst had been conducted. Titanium tetraisopropoxide (TTIP) was used as a precursor of Ti source, reacted to ZrO2 powderand CuSO4·5H2O with variou... see more

First-principle calculations have been performed to investigate the electronic structure and optical properties of ZnO co-doped with Nb and Ta. The three doping structures are set to: Zn0.9375Nb0.0625O, Zn0.9375Ta0.0625O and Zn0.875Nb0.0625Ta0.0625O. The ... see more

The crystalline compounds CaMoO4 doped with Eu3+ ions were prepared from nitrate-tartrate precursor gels at 650, 700, 750 and 800°C temperatures. The obtained samples were characterized by thermal analysis (TG/DSC), Furier Transform infrared spectroscopy ... see more
