Composite Aerogel for Heat Insulation
Chemical Engineering Transactions, 2020 Silica aerogels are often brittle and MTMS is rather expensive. Therefore, it is necessary to strengthen MTMS silica aerogels and lower their cost. In this research, hydrophobic composite monolithic methyltrimethoxysilane (MTMS) based aerogels were investigated.

Testing Method for Composite Insulators Interface Based on Nonlinear Ultrasonic
IEEE Access, 2019 The interface is the weakness of composite insulators. As the interface bonding fails, the uniform distribution of electric field will be affected, which accelerates the aging of composite insulators and affects the safe operation of transmission lines ...

Spin-Orbital Entanglement and Violation of the Goodenough-Kanamori Rules
, 2006 We point out that large composite spin-orbital fluctuations in Mott insulators with $t_{2g}$ orbital degeneracy are a manifestation of quantum entanglement of spin and orbital variables.

Dual QED3 at "NF = 1/2" is an interacting CFT in the infrared [PDF]
, 2016 We study the fate of weakly coupled dual QED3 in the infrared, that is, a single two-component Dirac fermion coupled to an emergent U(1) gauge field, but without Chern-Simons term.
