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
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.
On February 15th 1946, ENIAC (the Electronic Numerical Integrator and Computer), the world’s first programmable electronic computer made its debut. Thomas Haigh, author of the recently released ENIAC in Action, discusses the milestone and its significance.
