Published in 2017 at "International Journal of Quantum Chemistry"

DOI: 10.1002/qua.25352

Abstract: Heteroaromatic hydrocarbons (including thiophene [TH], benzothiophene [BT], and dibenzothiophene [DBT]) do not have apparent functional groups capable of interacting with the silica-oxide tetrahedral surface of kaolinite. Thus, question remains concerning what would be the driving… read more here.

Published in 2017 at "Probability Theory and Related Fields"

DOI: 10.1007/s00440-016-0725-1

Abstract: The random-cluster model has been widely studied as a unifying framework for random graphs, spin systems and electrical networks, but its dynamics have so far largely resisted analysis. In this paper we analyze the Glauber… read more here.

Published in 2017 at "Journal of Physical Chemistry C"

DOI: 10.1021/acs.jpcc.7b04126

Abstract: An embedded cluster model with either a large number of point charges (PCs) or periodic electrostatic (PE) potential was proposed to incorporate the electrostatic effects by the bulk surface and applied to non-transition-metal oxide supports… read more here.

Published in 2021 at "Smart Materials and Structures"

DOI: 10.1088/1361-665x/ac40de

Abstract: The existing research on magnetorheological elastomer (MRE) mainly focused on the improvement of MRE formula and structural design of MRE devices. As to the microscopic mechanism, less research has been done. Based on the scanning… read more here.

Published in 2019 at "Progress of Theoretical and Experimental Physics"

DOI: 10.1093/ptep/ptz046

Abstract: We apply the tensor version of the antisymmetrized quasi-cluster model (AQCM-T) to $^4\textrm{He}$ and $^8\textrm{Be}$ while focusing on the $NN$ correlations in $\alpha$ clusters. We adopt the $NN$ interactions including realistic ones containing a repulsive… read more here.
