Emergent coral reef terraces in northwest Luzon Island, Philippines are studied to understand relative sea level (RSL) changes and uplift along the Manila Trench forearc region during the Late Quaternary. Coral reef sequences in Currimao, Badoc, and Badoc Island were mapped and were described based on geomorphological characteristics, elevation patterns, and ages. The lower emergent coral reef terraces,...
Recent 230Th dating of fossil corals in west Luzon has provided new insights on the emergence of late Quaternary marine terraces that fringe west Luzon Island facing the Manila Trench. Apart from regional sea level changes, accumulated uplift from aseismic and seismic processes may have influenced the emergence of sea level indicators such as coral terraces and notches. Varied elevations of middle-to-late...
In this report, we use series of cobalt derivatives, conducting polymer and carbon materials as the counter electrodes to replace the conventional platinum in dye sensitized solar cells. The basic cobalt derivatives, Co12 and Co15, showed the capability as the counter electrode with proper short-circuit current (JSC) and open-circuit voltage (VOC), but the poor conductivity and redox ability result...
In this experiment, we use carbon black as counter electrodes to replace the conventional platinum electrodes in DSSCs. We discussed the properties and efficiency of carbon black counter electrodes by controlling the annealing temperature from 100 °C to 500 °C with various concentration of 0.5M, and 1.5M. After the proper annealing process, the conductivity and redoxing ability of the carbon black...
