To improve electron field emission properties of anodic aluminum oxide (AAO) templated Si nanotips, IrO2 nanoparticles were deposited on the nanotips using bipolar pulse electrodeposition method. The IrO2 nanoparticles had a uniform size distribution with an average value of approximately 4 nm, and well dispersed on the ordered Si nanotips. Due to the small(More)
Living organisms use fractal structures to optimize material and energy transport across regions of differing size scales. Here we test the effect of fractal silver electrodes on light distribution and charge collection in organic semiconducting polymer films made of P3HT and PCBM. The semiconducting polymers were deposited onto electrochemically grown(More)
The effect of varied anaerobic atmospheres on the metabolism of sweet potato (Ipomoea batatas [L.] Lam.) roots was studied. The internal gas atmospheres of storage roots changed rapidly when the roots were submerged under water. O(2) and N(2) gases disappeared quickly and were replaced by CO(2). There were no appreciable differences in gas composition among(More)
