Single-crystal X-ray diffraction analyses reveal that three diverse vanadium polyoxoanions, [V6O（18）]6- ring, [V（10）O（28）]6- cluster, and [V（12）O（35）]^10- ring, were isolated from the same reactant NH4VO3 under different conditions. The [CuL]^2＋ bridges the [V10O28]6- clusters to form a two-dimensional sheet in 2, and link the [V6O（18）]^6- rings in 1 and [V（12）O（35）]^10- rings in 3 into three-dimensional frameworks, respectively.展开更多

Kinokuni X C.ichanglemon, which gives an eatable lemon with a chemical composition similar to the normal lemon fruit and without any damage it can resist frost at -16 ℃ temperature and b） spontaneous mutations of trifoliata： #1 and #2 which are distinguished among trifoliata species. Their fruits don＇t contain or contain a small amount of the substances that deteriorate the taste： naringin, porcine and so on. They are characterized by high index of frost resistance. In the experiment when obtaining sexual hybrids of the Washington naval orange the above mentioned components were used and hybrid seedlings were obtained, which are distinguished according to their phenotypic hereditary features. Selected seedlings represent the best initial material for a successful future work.展开更多

Our ability to adapt intelligently to the challenges has ramifications all the way from fundamentally changing research itself, over applications critical to future survival, to posing globally existential dangers. Touching on specific issues such as how complexity relates to the catalytic prowess of multi-metal compounds, we discuss the increasingly urgent issues in nanotechnology also very generally and guided by the motto ＇Bio Is Nature＇s Nanotech＇. Technology belongs to macro-evolution; for example integration with artificial intelligence （AI） is inevitable. Darwinian adaptation manifests as integration of complexity, and awareness of this helps in developing adaptable research methods that can find use across a wide range of research. The second half of this work reviews a diverse range of projects which all benefited from ＇playful＇ programming aimed at dealing with complexity.
