Considerable interest has been focused on miniature biofuel cells (BFCs) because of their portability and possibility to be implantable. Origami devices with hollow channels will provide novel insight into the assembly methods of miniature BFCs. Herein a miniature origami BFC has been fabricated from a MnO2-graphite flake consumed solid-state cathode. For further practical applications, miniatu...

the effects of postharvest application of cobalt chloride were investigated on vase life of rose stood individually in vials and the other ones placing daffodil flowers in a vase with a rose flower.  therefore, roses were treated with: cocl 2 (100, 200, 300 mg l -1 , respectively) or distilled water (control). the results showed that the decreased vase life of rose flowers, after daffodil was p...

Stingless bees may produce both large queens and "miniature" queens, but the adaptive significance of this is uncertain. Using biometry and statistical analysis we determined the proportion of miniature queens in Plebeia remota that were either mated (14%) or virgin (45%). Mated queens were mostly normalsized which indicated that they were more successful. Nevertheless, the presence of miniatur...

The structure of the miniature three–dimensional (3-D) inductor is presented in this paper. The proposed miniature 3-D inductors have been fabricated in a standard digital 0.35m one-poly-four-metal (1P4M) CMOS process. According to the measurement results, the self-resonance frequency SR of the proposed miniature 3-D inductor is 34% higher than the conventional stacked inductor. Moreover, the p...
