This study involved two experiments. A pot experiment was carried out at the Northeast Agricultural University Horticulture Station in Harbin, Heilongjiang Province, Northeast China (45°43′ N, 126°43′ E). Sod of each species was collected from turfgrass plots at the Horticulture Research Center...
the Department of Energy’s SLAC National Accelerator at Stanford University, the device is about half the size of a postage stamp and uses solar energy to disinfect water with bacterial contamination. The researchersreported their experiments in a paper this weekin the journal Nature Nanotechnology....
