After a freeze, California avocado growers should look for the following freeze indicators; firm, brittle, curled leaves, water - soaked or discolored wood or twigs, older branches and trunks splitting and losing bark, and discolored avocados, with hues ranging from barely visible bronze to black.
A research group led by Chengsi Pan, Postdoctoral Researcher, and Tsuyoshi Takata, NIMS Special Researcher, at the Global Research Center for Environment and Energy Based on Nanomaterials Science (GREEN; Director - General: Kohei Uosaki) of the National Institute for Materials Science (NIMS; President: Sukekatsu Ushioda), and Kazunari Domen, a professor of the Department of Chemical System Engineering, School of Engineering, The University of Tokyo (President: Junichi Hamada) newly developed a water - splitting photocatalyst that is operable over a wider range of the visible light spectrum than before.
«Novel water - splitting photocatalyst operable over wide range of the visible light spectrum.»
Most of the conventionally developed water - splitting photocatalysts, however, were only active under UV irradiation, and only a few have been demonstrated to operate under visible light, at up to 500 nm.
This made LaMg1 / 3Ta2 / 3O2N solid solutions usable for water - splitting reactions by visible light irradiation, but since the degradation of the photocatalyst and the reverse reaction simultaneously occurred, a steady water - splitting reaction could not be achieved.
Bao said photocatalytic water - splitting experiments have been tried since the 1970s, but this was the first to use cobalt oxide and the first to use neutral water under visible light at a high energy conversion efficiency without co-catalysts or sacrificial chemicals.
