Experimental and Theoretical Studies on the Effects of Magnetic Fields on the Arrangement of Surface Spins and the Catalytic Activity of Pd Nanoparticles
Nanocatalysts
have very high catalytic activities due to surface atoms with their
unpaired spins. It is the purpose of this paper to investigate the
effect of magnetic fields (MFs) on the arrangement of surface spins
and their catalytic activities. Pd nanoparticles supported on MIL-100Â(Cr)
were selected as catalysts for the reduction of 4-nitrophenol under
MFs. The result demonstrates that MFs can reduce the reaction time
from 2.6 to 1.4 min under 0.5 T. This study first shows that the configuration
of surface spins has an effect on the catalytic activity, which can
be regulated by a foreign MF

Three evident and meaningful characteristics of disruptive technology are the zeroing effect that causes sustaining technology useless for its remarkable and unprecedented progress, reshaping the landscape of technology and economy, and leading the future mainstream of technology system, all of which have profound impacts and positive influences. The identification of disruptive technology is a universally difficult task. Therefore, this paper aims to enhance the technical relevance of potential disruptive technology identification results and improve the granularity and effectiveness of potential disruptive technology identification topics. According to the life cycle theory, dividing the time stage, then constructing and analyzing the dynamic of technology networks to identify potential disruptive technology. Thereby, using the Latent Dirichlet Allocation (LDA) topic model further to clarify the topic content of potential disruptive technologies. This paper takes the large civil unmanned aerial vehicles (UAVs) as an example to prove the feasibility and effectiveness of the model. The results show that the potential disruptive technology in this field is the data acquisition, main equipment, and ground platform intelligence.</div
