Cylindrical dye-sensitized solar cells with high efficiency and stability over time and incident angle – Chemical Communications (RSC Publishing)

We present here the realization of cylindrical dye-sensitized solar cells composed of Ti wire supported TiO2 nanotube anodes and transparent metal selenide counter electrodes. The optimized device yields a high efficiency of 6.63%, good stability over time, and identical efficiency output at arbitrary incident angl

Scientists prove feasibility of ‘printing’ replacement tissue

Using a sophisticated, custom-designed 3-D printer, regenerative medicine scientists have proved that it is feasible to print living tissue structures to replace injured or diseased tissue in patients.
