  • Patent number: 11738330
    Abstract: A method of synthesizing a doped carbonaceous material includes mixing a carbon precursor material with at least one dopant to form a homogeneous/heterogeneous mixture; and subjecting the mixture to pyrolysis in an inert atmosphere to obtain the doped carbonaceous material. A method of purifying water includes providing an amount of the doped carbonaceous material in the water as a photocatalyst; and illuminating the water containing the doped carbonaceous material with visible light such that under visible light illumination, the doped carbonaceous material generates excitons (electron-hole pairs) and has high electron affinity, which react with oxygen and water adsorbed on its surface forming reactive oxygen species (ROS), such as hydroxyl radicals and superoxide radicals, singlet oxygen, hydrogen peroxide, that, in turn, decompose pollutants and micropollutants.

  • Patent number: PP35378
    Abstract: The new cultivar of grape originated from a hand-pollinated cross of ‘Dunstan-210’ (female parent, not patented) and ‘Black Monukka’ (male parent, not patented) made in 1970. The seedlings fruited in the summer of 1973 in a vineyard near Clarksville, Ark. and one was selected for its potential as a table grape for utilization in the southern United States. The original vine was tested as ‘Ark. 1400’. The new cultivar of grapevine is a white, seedless table grape which provides advancements in Pierce's Disease tolerance (Xylella fastidiosa Wells et al.) for the southern region of the United States. This cultivar produces large, attractive fruit clusters with berries that have a neutral flavor and palatable, thin skin.
