Inspired by sunflowers, a bionic sunflower based on photo-responsive smart hydrogel was used as photocatalytic reactor and always exhibited relatively stable high H2O2 generation rate at any random angle of irradiation.

The theory of mixed hypergraph coloring was first introduced by Voloshin in 1993 and has been growing ever since. The proper coloring of a mixed hypergraph H = (X, C,D) is the coloring of the vertex set X so that no D-hyperedge is monochromatic and no C-hyperedge is polychromatic. A mixed hypergraph with hyperedges of type D, C or B is commonly known as a D, C, or B-hypergraph respectively wher...

Sunflower is one of the oil-producing plants that potentially can be developed as a food raw material, industrial, medicine, and cosmetics. cultivation needs to conducted in various lands Indonesia; them coastal regions. However, on side, these were included marginal land because high level salinity constrains it. This research aims determine sunflower growth thrive stress land. applies random ...

Identifiable endophytic bacteria with plant growth-promoting traits promise to ensure sustainable agriculture. However, information on the versatility and exploration of sunflower-associated as bioinoculants is less studied. Here, we present whole-genome sequence annotation Stenotrophomonas maltophilia JVB5 isolated from sunflower root endosphere North West province, South Africa. The analysis ...

In a survey of over 300 nonevergreen dicots in 69 families, many species were found to have translucent patterns attributed to the presence of bundle-sheath extensions (BSE) on the small and ultimate veinlets. The BSE have been shown by others to inhibit transverse air movement within leaves, and it has been suggested that they are important passageways between vascular tissue and the palisade....

The old adage, "records are made to be broken," certainly applies to plants. Each year gardeners from throughout the world compete with their largest tomatoes and squash, largest potatoes and turnips, largest orchids, tallest sunflowers and dozens of other superlative categories. Authenticated records of their prized fruits, vegetables and blossoms appear in the latest editions of the Guinness ...

»A woodpecker’s movement around a tree trunk defines a perfect spiral. To connect the hoppity helix of the woodpecker to the macrocosmic spiral of our stellar system or to the microcosmic spiral of the DNA molecule or, for that matter , to the hundreds of natural spirals in between snail shells, crowns of daisies and sunflowers, fingerprints, cyclones, etc. may be assigning to geometry more mea...
