Electricity from nuclear decay Can electricity be generated directly from nuclear decay? It occurred to me that in alpha decay two protons fly off rapidly, leaving their associated electrons behind. If the alpha particle was captured, perhaps by a conducting shell around a lump of the decaying element then a usable current migh... (more) |

Nuclear energy storage Could nuclear energy be a basis for energy storage with foreseeable technology? One approach would be to use excited nuclear states, but I suspect they would be too unstable to ever be useful. Alternatively, could nuclear fission be reversible? Put crudely, might it be possible to take the prod... (more) |

Do plants need ambient oxygen? Do {any, some, all} {unicellular, multicellular} plants require free oxygen? For example, would a cabbage asphyxiate over night, or even in daylight, in an oxygen-free atmosphere? (more) |

Producing hydrocarbons by electrolysis When water is electrolysed with graphite electrodes some of the oxygen reacts immediately with the anode to produce carbon dioxide. Does a similar reaction ever occur at the cathode, producing methane instead of hydrogen? If such a reaction takes place at all then Le Chatelier's principle suggests th... (more) |

A: How can we grow this community? Two ideas, prompted by a question I submitted recently. (About the chemistry of PVA glue.) Firstly, the topics are too narrow and exclude many, quite possibility the majority, of likely questions. In the case of my glue question there was no topic that seemed even remotely appropriate and I came v... (more) |

PVA glue curing process What happens when PVA glue sets? I am curious about the white PVA glue that is commonly used for bonding wood and paper. Although an Internet search find lots of articles they mostly seem to be near copies of one another and not even the Wikipedia article say much about the curing process. As far... (more) |
