Mr Peng Zhang obtained his BSc in July 2015 and MSc in January 2019 both from Fudan University. His research focused on oxygen reaction electrocatalysis and preparation of CDs, supervised by Prof. Huan-Ming Xiong. He will join The University of Sydney, Australia, in late 2019 to commence his PhD training. J. Zhou, J. Qin, X. Zhang, C. Shi, E. Liu, J. Li, N. Zhao and C.

We recommend using the smartDOT on your mobile phone as that is the device you carry with you most often. BioDOT has an energising effect with an element of relaxation and smartDOT has a stress-reducing physiological effect. In a customer survey overall 67% found they had improved focus and concentration since using bioDOT & smartDOT (105 out of 156) Technical SpecificationsM. Zhao, X. Liu, Q. Zhang, G. Tian, J. Huang, W. Zhu and W. Fei, ACS Nano, 2012, 6, 10759–10769 CrossRef CAS PubMed . The bioDOT can be used by adults (including pregnant women), children, babies, pets and even plants. The energetic programming is not affected by water so you can wear your bioDOT in the shower, bath or pool. A bioDOT can be placed in the fridge or under a fruit bowl to help keep your food in optimal condition.

We’re looking at exciton-diffusion length,” Mork explains. “Once one quantum dot absorbs a photon, it can do energy transfer, which is a non-radiative process, so it doesn’t emit a photon. Then another quantum dot absorbs, it just transfers the energy directly to another quantum dot, so it does energy transfer to some other number of quantum dots, and then where that photon is emitted relative to where it absorbed, is the exciton-diffusion length.” Both bioDOT™ and smartDOT® do not need replacing and will retain their programming signature indefinitely.

For Mork’s study, Tisdale notes that Mork’s lab colleague Mark Weidman traveled to the National Synchrotron Light Source at Brookhaven National Laboratory on Long Island, New York, to perform grazing-incidence small-angle X-ray scattering (GISAXS) and wide-angle X-ray scattering (WAXS) studies of quantum-dot films.
