We investigated the effect of temperature, oxidant and catalyst loading on the performance of direct formic acid fuel cell (DFAFC). When oxidant was changed from air to oxygen, the power density was increased to 17.3 mW/ cm2 at 25 ‡C. The power den

A series of CuO-Fe2O3 sorbents with 25 wt% SiO2 as a support were prepared based on a simple mixing method in order to evaluate the effects of Fe2O3 on their desulfurization reactivities. The initial reactivities of sorbents were tested by using a TG

Various CuO-based sorbents were prepared to investigate effects of sorbent ingredients such as SiO2, MnO2, and MoO3 on desulfurization reactivity. Several candidate sorbents chosen from a TGA screening test were further tested in a microreactor syste

We report on the control of coherent optical phonon oscillations in GaN using the femtosecond pulse shaping technique. The enhancement or the discrimination of the ${E}_{2}$ phonon mode is demonstrated depending on whether or not the spectral separat
